(1) Background: Limited research has examined elastic resistance preconditioning effects on post-activation performance enhancement (PAPE) using the rate of perceived exertion (RPE) as an intensity indicator. This pilot study aimed to evaluate the application of RPE to the elastic resistance push-press (ERPP) exercise performed at maximum velocity for its effects on PAPE. (2) Methods: Twenty-four trained, healthy young adults participated in this study and performed both a conventional warm-up and a warm-up combined with six repetitions of an elastic resistance push-press (ERPP) at 85% 1RM/RPE of the first repetition (RPE-1) of 6 out of 10. The pre-post variables assessed were push-ups, a countermovement jump (CMJ), and 10 and 20 m sprints. A repeated-measures ANOVA was conducted. Additionally, between-subject variability was adjusted for individual performance. (3) Results: In the push-up, a significant improvement (p ≤ 0.05) of 20.41% in mean propulsive velocity was observed among the less strong participants. A medium effect size improvement (d = 0.47; p = 0.13) was observed in CMJ performance (7.93%) among the less strong participants. Significant improvements were noted in sprint performance over 10 m (8.07%) and 20 m (6.23%) in the ERPP group compared with the standard warm-up, particularly in the less strong participants. The stronger participants exhibited no significant changes in either variable. (4) Conclusions: We concluded that ERPP effectively induced PAPE in the less strong participants. Additionally, RPE-1 is proposed as a tool to monitor intensity in elastic band resistance to induce PAPE. Full article

Objective: Most recreational gym-goers independently consume nutritional supplements (NSs) without physician advice and a personalized diet. The present study examines the preference for nutritional supplements (NSs) based on protein and amino acids of 218 recreational gym-goers (males and females aged 18–60). It also investigates the NS’s impact on resistance training (RT) performance. Methods: All participants (n = 218) were regular members of two gym centers in Oradea. Baseline data and information about daily diet and supplement preferences were obtained through face-to-face interviews. At the same time, RT performance was assessed by measuring 1RM in six exercises three times (W0, W4, and W8). Results: Our findings reveal that 24.3% of participants did not consume NSs, while the majority (75.6%, p < 0.05) used them to improve their physical condition; men were more likely to consume NSs than women (83.3% vs. 63.9%, p < 0.05). Gym-goers were grouped based on their NS consumption: L-carnitine, creatine, whey protein (WP), and triple combination; the non-supplemented group was the control. The combination substantially correlated with a balanced diet, 3001–3500 and >3500 calories/day; creatine was appreciably associated with 2001–2500 calories/day; L-carnitine was associated with 151–200 g protein/day, while control was considerably linked with a vegetarian diet and <1000 calorie/day (r > 0.900, p < 0.05). The results showed that almost all participants exhibited progressive muscle strength improvements. As an overview, 1RM substantially varied with NS consumed, body weight status, and gender (p < 0.0001), except for the pull-up count, which varied with NS and gender (p < 0.0001). Additionally, 1RM significantly varied with age (deadlift and pull-ups), daily protein consumption (back squats, biceps, and triceps), daily calories (back squats), and diet type (biceps, triceps, and pull-up exercises), p < 0.05. On the other hand, most NSs associated with RT exercises led to a general increase in body weight. Only L-carnitine decreased it. Conclusions: Resistance training records of recreational athletes are significantly influenced by age, gender, body weight status, NS type, and daily diet features (p < 0.05). Our findings highlight the essential role of professional guidance in nutritional supplementation associated with a suitable diet for optimal RT performance of recreational athletes. Full article

Physiological characteristics such as VO_2max, running economy (RE), maximal aerobic speed (MAS), maximal sprinting speed (MSS), anaerobic speed reserve (ASR), and player profiling (based on MSS and MAS) have been proven to be important for training prescriptions in football. However, previous studies on player profiling have neglected the absolute values of MSS and MAS. The objectives of this study were to compare the aforementioned physiological variables among player roles, create benchmarks, and provide normative data to help coaches categorize players, ultimately proposing a new player profiling method. We analyzed 195 male professional football players (50 forwards, 59 midfielders, 44 full-backs, and 42 center-backs). Multivariate analysis of variance with Tukey’s post hoc tests revealed positional differences. Center-backs exhibited lower VO_2max than midfielders and full-backs. Both center-backs and forwards showed poorer RE and MAS compared to midfielders and full-backs. Full-backs achieved higher MSS than midfielders and center-backs, and forwards outperformed center-backs. Finally, midfielders demonstrated lower ASR than all other positions. Benchmarks based on T-scores for all variables were provided. Finally, in the new profiling method proposed—also based on T-scores—players were classified as “speed”, “endurance”, or “hybrid” if their MAS and/or MSS T-score exceeded 60, “in development” if both were below 45, and “average” if both scores were between 45 and 60 without any value above 60. The normative data provided can assist coaches in identifying specific areas for improvement in players’ physical conditioning—particularly valuable for youth athletes or those returning from injury. Additionally, the new profiling method offers insights into individual player characteristics, enabling more tailored and effective training interventions. Full article

The effects of physical activity on skeletal muscle mass and cardiac function are well-documented, but there is limited information on the relationship between the two. Furthermore, differentiating between the ‘athlete’s heart’ and pathological cardiac conditions often presents challenges. We aimed to analyze resting echocardiographic parameters in elite water polo athletes, considering sex, anthropometrics, and body composition. We examined 161 youth and adult athletes (age: 19.7 ± 5.6 years, male: 50.9%). Data analysis was performed with R software (version 4.2), using multivariate linear regression models. Confounders besides the main predictor were sex, age, and height. Male players had higher weight (87.55 ± 12.83 vs. 69.77 ± 9.8 kg), height (188.59 ± 6.82 vs. 173.47 ± 6.76 cm), skeletal muscle mass (SMM, 43.87 ± 5.50 vs. 30.38 ± 3.95 kg), and fat-free mass (FFM, 76.60 ± 9.23 vs. 54.52 ± 6.68 kg) and lower percentage of body fat values (12.14 ± 4.00.vs 21.51 ± 4.76%) compared to the female players. Youth players had lower height (178.51 ± 9.53 vs. 186.74 ± 9.27 kg) and weight (74.34 ± 12.12. vs. 88.23 ± 14.66 kg) compared to adults. Left ventricular end-diastolic and end-systolic diameters correlated positively with SMM (Est: 0.38, StE: 0.08, p < 0.001 and Est: 0.42, StE: 0.11, p < 0.001) and FFM (Est: 0.25, StE: 0.05, p < 0.001 and Est: 0.25, StE: 0.06, p < 0.001). Right ventricular end-diastolic diameter correlated positively with SMM (Est: 0.18, StE: 0.08, p < 0.05) and FFM (Est: 0.12, StE: 0.05, p < 0.05). Interventricular septal wall thickness showed positive correlation with SMM (Est: 0.16, StE: 0.04, p < 0.001) and FFM (Est: 0.10, StE: 0.02, p < 0.001). Left ventricular posterior wall thickness correlated with SMM, with a stronger correlation in females (Est: 0.17, StE: 0.05, p < 0.001) than in males (Est:0.7, StE: 0.04, p < 0.05). The close relationship between body composition and cardiac dimensions provides an opportunity for professionals to distinguish between athlete’s heart and pathological conditions. Full article

Background: Understanding the physical demands of basketball at different competitive levels is essential for optimizing training and performance. While elite players are often assumed to experience the highest physical loads, evidence comparing peak external demands (PDs) between elite and non-elite athletes using time-window analysis is limited. Therefore, the aim of this study was to examine how player level (Elite vs. Non-Elite) influences the external PDs experienced by male basketball players. Methods: This study examined PlayerLoad™ (PL) PDs in elite (n = 10) and non-elite (n = 11) male basketball players during the 2023–2024 season. Players were monitored using inertial measurement units (IMUs) during official and friendly matches (elite = 8 games; non-elite = 29 games). Peak PL values were computed using rolling averages across 30-s, 1-min, and 3-min time windows. Linear mixed-effects models were employed to examine differences between groups, adjusting for age and match nature. A secondary analysis was carried out including only friendly matches. Results: Non-elite players exhibited significantly higher PL PDs across all the time windows (p < 0.001), with effect sizes ranging from small to very large in the main analysis (ES = −0.41 to −2.11) and from very large to extremely large in the secondary analysis (ES = −2.68 to −5.06). Differences were more pronounced in longer durations. These results suggest that non-elite athletes sustain higher physical loads, possibly due to less efficient movement patterns and lower tactical regulation. Conclusions: Elite players display lower peak external loads than their non-elite counterparts, likely due to superior cognitive, tactical, and perceptual abilities that enhance movement economy. Training programs should incorporate tasks that combine physical intensity with decision-making demands to foster efficiency and potentially reduce injury risk. Full article

Organized sports are assumed to boost overall physical activity, but evidence suggests structured training does not always increase general activity outside formal sessions. This study explores the link between physical activity levels and weekly training hours in adolescent athletes across sports and competition levels. A total of 10,196 participants aged 11 to 19 were included in the analyses. Participants were classified into seven groups: inactive, somewhat active, non-competitive athletes, and athletes competing at the local, regional, national, or international level. They completed the Spanish version of the Physical Activity Questionnaire and answered questions regarding their performance level, training volume, and socioeconomic status. Girls exhibited lower physical activity levels than boys, even at higher competition levels where both sexes had comparable training hours. Competitive athletes reported the highest physical activity levels. In competitive athletes, physical activity levels decreased with age despite a substantial increase in weekly training hours. They were similar across athletes competing in different sports and at different levels, despite significant differences in training hours. Many athletes, including those at the national and international levels, displayed low physical activity levels, and no clear relationship was found between physical activity level and weekly training hours. The current study provides valuable insights into adolescent physical activity patterns by sex, age, sport, and competition level. Girls showed lower physical activity than boys, even with similar training hours. Physical activity levels declined with age despite increasing training volumes, and no strong association was observed between physical activity and weekly training hours. These results reveal a discrepancy between structured training and overall activity levels, challenging assumptions about the impact of sports participation on daily physical activity. Full article

Background/Objectives: Various studies have investigated the importance of perceptual–cognitive skills in decision-making and the expert performance of athletes. However, bibliometric study has yet to identify research trends on this topic. The objective of this study was to perform a bibliometric review to identify the research trends in the study of soccer decision-making. Method. A total of 172 studies were included in the databases. Results. The year 2021 was the year with the highest number of published studies (n = 23), and 2016 was the year with the highest number of citations (n = 692). The average number of citations per document was 19.79. The concepts that have the greatest occurrence in the investigations are performance (n = 68), decision-making (n = 54), expertise (n = 32), skill (n = 23), and anticipation (n = 22). The journals with the highest number of published documents are the Journal of Sport Sciences (10 documents and 437 citations) and PLoS One (11 documents and 349 citations). The countries with the highest number of published documents and citations are England (n = 46 documents and 996 citations), Germany (n = 32 documents and 749 citations), and Spain (n = 38 documents and 597 citations). German Sport University Cologne is the organization that has the most publications and citations (n = 19 and 531). Conclusions. Existing knowledge production on decision-making in soccer has a preference for the study of two major categories: one related to the analysis of the factors associated with perceptual–cognitive skills, mental fatigue, anticipation, creativity, and memory, whereas the second is more related to the study that has decision-making in the manifestations of specific game performance, between experts and novices, in the precision of technical actions, such as the pass, as well as in a methodology for the selection of athletes.

Objectives: The purpose of the present study was to investigate the relationship between acute and chronic loads, and the fatigue response within male elite professional football players. Design: 40-week longitudinal study across the 2021–2022 season in the English Championship. Methods: Twenty-three outfield football players had workload measured using global positioning system (Distance, High-Intensity Distance and Sprint Distance) and perceived exertion. Load-response was measured via a perceived wellbeing questionnaire, counter-movement jump (CMJ) and salivary immunoglobulin A. Results: General estimating equation models identified 18 significant interactions between workload and load-response markers. Thirteen significant interactions were found between acute and chronic workloads and CMJ variables, jump height, eccentric duration and flight contraction time. A poor CMJ was observed when acute sprint workload was >+1 standard deviation and chronic distance increased. However, when chronic perceived exertion increased, and acute sprint workload was >+1 standard deviation an advantageous response was detected on counter movement jump variables. The S-IgA response to acute and chronic workload was more variable; when chronic loads were >+1 standard deviation above mean values and acute workload increased, salivary immunoglobulin A was both suppressed and elevated depending on the interacting acute variable. Higher chronic workload was associated with better perceived wellbeing, even when acute workload was >+1 standard deviation above the mean. Conclusion: In general, low chronic workloads and acute spikes in workload were associated with poorer neuromuscular and immune function. Furthermore, CMJ performance and perceived wellbeing improved when chronic workloads were higher, despite the occurrence of acute spikes in workload. Full article

This study examined the use of linear regression models for predicting the outcomes of a six-week velocity-based training (VBT) intervention in female floorball players. The intervention was integrated into regular training and consisted of brief 30-min sessions focused on back squats and trap bar deadlifts. Key performance metrics included neuromuscular adaptation, sprint speed, jump performance, stop-and-go (SAG) performance, and load-velocity profiles. Seventeen participants completed 12 training sessions, a strength block set (Sessions 1–6) and a power block set (Sessions 7–12). The predictive models explained 54% to 79% (

R^{2}

= 0.54–0.79) of the performance improvement in the strength-related tests. Significant gains were observed in neuromuscular metrics, including estimated one-repetition maximum (1

{RM}_{e s t}

) and average mean concentric velocity for both exercises. These findings underscore the predictive potential of VBT in enhancing strength and power while highlighting the need to integrate task-specific exercises to optimize sport-specific performance. This study provides valuable insights for tailoring VBT strategies for female athletes in high-demand team sports such as floorball. Full article

This study aimed to explore the relationship between perceived stress, burnout, and mental toughness, and investigate how mental toughness mediates the relationship between perceived stress and burnout among Hungarian coaches. Three hundred and thirty-three active coaches completed anonymous self-report questionnaires assessing burnout (CBQ), mental toughness (SMTQ), and perceived stress (PSS). In the international comparison, Hungarian coaches indicated significantly higher burnout levels than those investigated in previous international research. PLS-SEM results showed that coaches with higher stress levels are less likely to experience burnout. Furthermore, mental toughness serves as a buffer between stress and burnout; however, the buffering effects of its various subfactors on different dimensions of coaching burnout vary. Consequently, further research is necessary to fully understand the mitigating effects of mental toughness, particularly by analyzing coping strategies, motivation, and success. Our research unequivocally indicates that the integration of targeted stress management training into coaching education is crucial for effectively addressing the emotional challenges inherent in the profession. By incorporating workshops that focus on self-awareness and emotion regulation strategies, coaching programs can substantially reduce the risk of burnout and promote the well-being of coaches. These findings underscore the vital importance of embedding practical stress management interventions within coach development initiatives to cultivate more resilient and effective coaching professionals.

This study examines six decades (1964–2023) of changes in motor skills and body dimensions among Japanese 13-year-old students, analyzing grip strength, handball throwing, 50 m dash, endurance running, and composite scores. National Physical Fitness and Motor Skills Survey data were analyzed alongside School Health Examination Survey measurements to identify trends and correlations between performance metrics and anthropometric variables. The results revealed distinct developmental patterns, with motor skills peaking in the 1980s for both genders, followed by decline until 2000, after which boys experienced stagnation while girls showed improvement until 2019. Both genders demonstrated marked decreases following 2020, coinciding with the COVID-19 pandemic. Notably, while height increased significantly over the study period, only boys’ 50 m dash performance showed strong positive correlations with height (r = 0.779) and BMI (r = 0.854). This longitudinal analysis demonstrates how interdisciplinary factors—including educational policy shifts, reduced physical education curriculum hours, changes in urban park design, diminished outdoor play opportunities, and increased sedentary behaviors—collectively impact children’s motor development. These findings hold significant implications for public health initiatives and sports education strategies aimed at reversing concerning trends in youth physical capabilities and addressing the substantial post-pandemic decline in motor performance.

Dementia-friendly walking football offers a way of helping people who are less likely to engage with traditional services to participate in physical activity and support their physical, mental and social wellbeing. This addresses a gap in the current provision of post-diagnostic dementia support in the UK. However, there is a lack of evidence around such models of service provision. Through the evaluation of a newly established dementia-friendly walking football initiative provided by a Premier League charitable foundation, we explored the social, physical and mental benefits of dementia-friendly walking football for older males from underserved communities. Using a qualitative, exploratory approach, we held focus groups with service providers and service users to understand their views and experiences of delivering and attending dementia-friendly walking football sessions. A thematic analysis of the focus groups revealed three main themes relating to the importance of football to cultural and individual identity, namely, ‘for the love of the game’, ‘team players’ and ‘a game changer’. We also highlight how a multi-disciplinary, research-based approach to the evaluation of a service and identification of service improvements can both involve and benefit people living with dementia and their families.

The purpose of this study was to assess whether a simple and reproducible battery of jump tests can distinguish between patients affected by chronic ankle instability (CAI) and control subjects. The hypothesis was that patients with CAI would demonstrate lower performance compared to healthy subjects during jumping tasks. Twenty-one young, active adults aged 18 to 45 years affected by CAI were matched for sex, age, and body mass index (BMI) to a control group of 21 healthy subjects without history of lower limb pathology. Jumping ability was instrumentally assessed by an infrared optical acquisition system using a test battery, including mono- and bipodalic vertical squat jumps, countermovement jumps (CMJs), a drop jump (DJ), and a side-hop test. Patients with CAI had significantly worse monopodalic CMJ, DJ, and side-hop test scores in their involved limb compared to the non-dominant limb of healthy individuals. Pathological limbs of CAI patients reported inferior results compared to non-dominant limbs of healthy individuals while performing monopodalic CMJs, DJs, and side-hop tests (p < 0.05). No statistically significant differences were found between the two groups in the limb symmetry index (LSI) while performing monopodalic CMJs and DJs (p = 0.072 and p = 0.071, respectively), while a difference was found between the two groups, in favor of healthy subjects, while performing monopodalic side-hop tests (p < 0.01). A reproducible battery of jump tests performed with a simple and low-cost instrument can be applied in the clinical setting allowing for reliable measurements of functional ability of subjects with CAI. Our findings support the idea that side-hop tests could be more accurate than vertical jump tests for detecting functional deficits in patients suffering from CAI. Full article

Air pollution is an escalating global concern with significant implications for human health and athletic performance. This narrative review synthesizes and critically compares the current literature on the impact of air pollution on health and football performance, elucidates the physiological mechanisms involved, and evaluates available mitigation strategies. Comparative studies consistently demonstrate that football players—who frequently engage in high-intensity outdoor exercise—are particularly susceptible to the harmful effects of airborne pollutants such as particulate matter (PM), volatile organic compounds (VOCs), nitrogen dioxide (NO₂), ozone (O₃), and carbon monoxide (CO). These pollutants bypass natural respiratory defenses due to increased pulmonary ventilation during exercise, reaching deeper lung regions and triggering oxidative stress, inflammation, and impaired lung function. Evidence across studies indicates that poor air quality is associated with decreased football performance, including reduced distance covered, fewer high-intensity efforts, elevated physiological strain, and diminished training adaptation. Long-term exposure exacerbates respiratory conditions, suppresses immune function, and heightens the risk of illness and injury. Furthermore, comparative genetic research highlights inter-individual variability in pollution sensitivity, with specific gene variants conferring either increased vulnerability or resilience to adverse effects. This review also explores practical and emerging mitigation strategies—such as timing training to avoid peak pollution, utilizing air quality monitoring and antioxidant-rich diets, and promoting sustainable infrastructure—to safeguard athlete health and optimize performance. Novel approaches including respiratory training, anti-smog masks, indoor sessions, and personalized recovery protocols offer additional protection and recovery support. Full article

Athletes engaged in dynamic sports experience a shortened red blood cell (RBC) lifespan and accelerated turnover due to RBC destruction. This accelerated RBC turnover might have a positive impact on exercise performance by increasing the number of young red blood cells with a high oxygen-carrying capacity. However, accelerated turnover might also be a result of intravascular haemolysis caused by RBC destruction during exercise, impairing RBC function and oxygen transport. Therefore, we aimed to evaluate the relationship between reticulocyte count as an indicator of short-term RBC profile changes and exercise capacity. We retrospectively evaluated elite Italian athletes engaged in endurance or mixed sports disciplines selected for the 2023 European Games or 2024 Olympic Games. Athletes underwent blood tests, echocardiography, and cardiopulmonary exercise tests. We assessed the relationship between reticulocytes and the peak value of VO₂ (peak VO₂) and anaerobic threshold (AT). In addition, the effects of age, sex, haemoglobin concentration, stroke volume, peak heart rate, and reticulocytes on peak VO₂ and AT were assessed using multiple linear regression. Of the 105 athletes, reticulocyte count (0.059 ± 0.024 × 10¹²/L) negatively correlated with peak VO₂ (45.5 ± 9.1 mL/min/kg) (p = 0.022) and AT (27.6 ± 7.9 mL/min/kg) (p = 0.040). Using multivariate linear regression analysis, reticulocytes were independent predictors of peak VO₂ and AT (95% confidence interval: −192.3 to −45.9; p = 0.001; 95% confidence interval: −143.4 to −13.8: p = 0.018, respectively). Our findings indicated a negative relationship between reticulocyte count and peak VO₂ or AT. The life span of reticulocytes was close to the period of transient decline in RBC function that occurred after high-intensity exercise; therefore, the changes in reticulocytes might be related to the decline in exercise performance owing to this decline in RBC function.

This systematic review and meta-analysis aimed to investigate the effectiveness of exercise interventions in regulating inflammatory biomarkers among individuals with musculoskeletal pain. A comprehensive search of MEDLINE, CINAHL, Web of Science, Cochrane Library, and Google Scholar was conducted from inception to November 2024. Only randomized controlled trials (RCTs) published in English that examined the effects of exercise on inflammatory markers—such as C-reactive protein (CRP), interleukins (ILs), and tumor necrosis factor-alpha (TNF-α)—were included. Twenty-three RCTs involving 1128 participants met the inclusion criteria. Meta-analysis of four studies indicated that isokinetic exercise significantly reduced CRP (MD = −0.40, 95% CI: −0.44 to −0.36, p < 0.01, I² = 0%), IL-6 (MD = −1.59, 95% CI: −2.61 to −0.56, p < 0.01, I² = 97%), and TNF-α (MD = −4.24, 95% CI: −5.13 to −3.36, p < 0.01, I² = 90%) levels compared to general exercise. These findings suggest that exercise, particularly isokinetic exercise, may reduce systemic inflammation in patients with musculoskeletal pain and provide therapeutic effects beyond mechanical improvement. The review followed PRISMA guidelines and was registered on PROSPERO (CRD42024500081). Full article

Critical speed (CS), the respiratory compensation point (RCP), and the midpoint between gas exchange threshold and maxial oxygen uptake (VO_2max) (i.e., 50%Δ) have been considered indexes able to demarcate the boundary between the heavy and severe exercise domains. However, the agreement between these indexes—and therefore the validity of using them reciprocally—remains to be reported in running. The current study analyzed the agreement between RCP, 50%Δ, and CS. Twelve young runners performed an incremental test to assess VO_2max, RCP, and 50%Δ, with CS estimated by the linear model of time-limited trials at 90, 95, and 110% of the speed corresponding to VO₂max. One-way ANOVA showed no differences when comparing VO₂ and running speed at CS vs. 50%Δ vs. RCP (47.5 ± 4.4 vs. 46.6 ± 4.4 vs. 47.8 ± 4.5 mLO₂∙kg⁻¹∙min⁻¹; and 13.9 ± 1.3 vs. 13.7 ± 1.3 vs. 14.0 ± 1.4 km∙h⁻¹; p > 0.05 for all comparisons). The bias for 50%Δ vs. CS was −0.82 ± 1.55 mLO₂∙kg⁻¹∙min⁻¹ and −0.23 ± 0.55 km∙h⁻¹, and for RCP vs. CS, it was 0.36 ± 1.21 mLO₂∙kg⁻¹∙min⁻¹ and 0.05 ± 0.46 km∙h⁻¹. Therefore, the agreement between RCP, 50%Δ, and CS in estimating VO₂ responses and running speed did not preclude their reciprocal similarity in exercise intensity, although the observed individual variability in physiological variables is a constraint on considering these indexes interchangeable.

Background: Little is known about the perspectives of elite female rugby union players and practitioners towards rehabilitation and return to play (RTP) following shoulder injuries and how to manage these complex injuries. Methods: An interpretive hermeneutic phenomenology study was undertaken within a subtle realist paradigmatic view. Twenty semi-structured interviews were conducted with elite female rugby union players and practitioners working in elite female rugby union. Data were analysed using reflective thematic analysis. Results: Four themes emerged from the data: (1) growth of the women’s game, which involved several influences on the support and resources players received; (2) different viewpoints between players and practitioners concerning injury reporting and objective testing; (3) threats to identity, a player-only generated theme centred around the risk to their career following a significant injury and the isolation they faced; and (4) RTP, exploring strategies and influences to players’ and practitioners’ confidence in the RTP process following a shoulder injury. Conclusions: Practitioners should consider the non-physical factors during the rehabilitation process and the theory of care concept in supporting and collaborating with female rugby union players following a shoulder injury.

Sports participation according to socioeconomic status (SES) was related to children in high-income Western countries. This study aimed to examine whether family or neighborhood-level SES is associated with current and continued organized sports participation, including the types of sports, among Japanese primary school children from preschool onward. The participants consisted of 269 girls, 255 boys, and their parents. Data on the type of sports participation at the current school or preschool, parental employment, and education were collected by questionnaire. Neighborhood-level SES was evaluated by the average annual income within 4 km of each school. The odds of sports participation was higher among children with mothers identifying as housewives or those with mothers employed part-time. Among girls, the odds of continued sports participation were lower if their mothers were junior high school or high school graduates or junior college/vocational school graduates. The odds of sports type like swimming were higher for children whose mothers had part-time jobs. Lower average community income was associated with lower participation in football and higher participation in baseball. These findings suggest that mothers’ employment and academic background are important correlates of sports participation for children, with variations observed by sport type and gender. Full article

We examined the effects of resistance training over 1.5 years (two seasons). Body mass, strength, power, and aerobic capacity were assessed during the first 1.5 years of a standardised, progressive, blocked linear periodisation training program in adolescent males with no prior history of resistance training (N = 11, 16.4 ± 0.5 years). Testing occurred during the start of pre-season (SPS), end of pre-season (EPS), and end of season (EOS) during the first and second year of resistance training. Changes over time were assessed with within-group ANOVAs and follow-up independent t-tests. Differences in relative change that occurred during the first and second year of training for each variable were assessed with dependent t-tests. Body mass changed over time (p < 0.001, n²p = 0.794). Body mass increased from SPS to EPS (p = 0.008, Large) and EPS to EOS (p = 0.019, Large) in year 1, and from EOS in year 1 to SPS in year 2 (p < 0.001, Large). Bench press (p < 0.001, n²p = 0.806), squat (p < 0.001, n²p = 0.670), and medicine ball throw (p < 0.001, n²p = 0.350) changed over time. Bench press (Year 1: p < 0.001, Large; Year 2: p < 0.001, Large), squat (Year 1: p < 0.001, Large; Year 2: p < 0.001, Large), and medicine ball throw (Year 1: p = 0.007, Large; Year 2: p = 0.026, Large) increased from SPS to EPS in year 1 and year 2. Bench press (p = 0.010, Large) and squat (p = 0.004, Large) increased more from SPS to EPS during year 1 than year 2. By quantifying diminished returns, our study offers practitioners novel information, helping practitioners manage expectations, avoid excessive training and support long-term adolescent development.

This longitudinal study investigated the incidence and characteristics of injuries among U9, U11, and U13 male football players in an academy setting over a six-season period, from 2016/17 to 2021/22. A total of 374 injuries were analyzed, with a particular focus on muscle injuries, including Delayed Onset Muscle Soreness (DOMS), muscle ruptures, and contusions. The study revealed that the highest injury incidence occurred in the U13 group, with quadriceps injuries being most prevalent in both the U13 and U11 groups. The study found that muscle injuries accounted for a significant proportion of all injuries, particularly in the U13 group, where muscle injuries increased over time. Intrinsic factors such as physical development during puberty and extrinsic factors like training intensity and psychological pressures may contribute to the higher injury rates in older age groups. Additionally, seasonal fluctuations in injury rates were observed, with a notable decline during the COVID-19 lockdowns in 2019/20 and 2020/21, followed by an increase post-lockdown due to deconditioning. The study highlights the vulnerability of young athletes to muscle injuries, particularly during growth spurts, and calls for further research into training methods and injury prevention strategies to mitigate these risks.

This study explores how age influences the relationship between physical performance (PP) and technical–tactical parameters (TPs) in youth soccer, analyzing 80 matches across four age groups: U15, U17, U19, and NB1 (adults). Team-level data were examined to assess how maturation affects the integration of physical and technical demands. Physical metrics included total distance (TD) and total high-intensity distance (THID), while TP metrics involved actions such as pressing, tackling, and ball possession. Pearson’s correlations and general linear models (GLMs) were used to identify associations between PP and TPs across age categories. The results showed age-related trends in performance integration. U19 and NB1 players demonstrated moderate-to-strong correlations between PP and TP variables, with TD and THID positively associated with pressing and tackling, indicating increasing synergy with age. U17 players showed emerging integration, while U15 players exhibited no significant correlations, suggesting developmental variability. Limitations include reliance on team-level correlational data and the absence of individual physiological or cognitive assessments. These findings suggest that training approaches should be tailored to players’ developmental stages, with increasing emphasis on combining physical conditioning and tactical understanding as players mature.

Background: Optimal health requires self-direction for exercise regime consistency. Boredom may cause abandoning regular exercise. Experiencing psychological flow—a concept psychologist Csikszentmihalyi originated—may avert boredom. Method: A search of post-2020 peer-reviewed publications following the PRISMA-ScR guidelines for scoping reviews investigates the range of research on this topic. The databases searched are OVID, ProQuest, PubMed, Scopus, Web of Science, and Google Scholar. The keywords are “Csikszentmihalyi AND flow AND exercise AND boredom”. Included returns contain all the keywords. Those excluded are reviews, books, reports missing any keywords, non-English reports, reports not based on research studies, and research published before 2020. Results: Two databases returned the included results: OVID (n = 3) and Google Scholar (n = 8). Conclusions: (1) Boredom is not evident when experiencing exercise-programme psychological flow. (2) Psychological flow evolves with self-directed changes in an exercise programme. (3) Successful exercise programme modifications during COVID-19 considered the imposed limitations. (4) Exercise regimes that are neither excessive nor extreme promote optimal health. And (5) optimal health accounts for exercise skill level and gender. Additionally, cognitive bias is avertable with a research team. Studies should include the research date and location and how flow reduces boredom, permitting accurate comparisons. Full article

Background: Knee injury risk screening protocols predominantly employ high-impact tasks (HIT), but there is a need for low-impact movement screening alternatives. This study aimed to investigate kinematic carryover between low-impact tasks (LIT) and HIT. Methods: This study employed a cross-sectional design. Eighteen healthy, active females with no history of injury within the last six months, aged between 18–35 years completed three trials of LIT (stand-to-sit, single-leg stand-to-sit) and HIT (drop vertical jump, single-leg drop vertical jump). Hip and knee three-dimensional kinematics were evaluated during LIT and HIT. Pearson correlation analyses were used to assess kinematic relationships between LIT and HIT. A post-hoc exploratory analysis examined the consistency of kinematic directionality across tasks. Results: In the frontal plane, the dominant hip, dominant knee, and non-dominant knee during LIT demonstrated a strong positive correlation and directional consistency with the corresponding values during HITs (p < 0.001). In the transverse plane, non-dominant hip, dominant knee, and non-dominant knee kinematics during LITs demonstrated directional consistency and a strong positive correlation with respective kinematics during HITs (p < 0.001). Conclusion: The similarities in hip and knee kinematic patterns suggest that motor responses may generalize across varying task intensities. Thus, LITs may be a useful tool in early knee injury risk identification. Full article

Aging is associated with physiological changes that increase the risk of falls, impacting functional independence and quality of life. Multicomponent exercise training has emerged as an effective strategy for mitigating these risks by enhancing strength, balance, flexibility, and aerobic capacity. This study aimed to evaluate the effects of a 30-week multicomponent training program on functional fitness and fall prevention in older women. A parallel, single-blind randomized controlled trial was conducted with 40 participants (aged ≥ 65 years), divided into an exercise group and a control group. The intervention combined strength, balance, coordination, and aerobic training, following international exercise guidelines for older adults. Functional fitness was assessed using validated tests, including the Timed Up and Go (TUG) test, lower limb strength, flexibility, and aerobic endurance measures. Results demonstrated significant improvements in the intervention group, particularly in TUG performance (p < 0.001), lower limb strength (p < 0.001), and flexibility (p < 0.05), indicating enhanced mobility and reduced fall risk. These findings reinforce the importance of structured, multicomponent training programs for aging populations, particularly women, who experience greater musculoskeletal decline due to menopause-related hormonal changes. Future research should explore long-term retention of benefits and optimize intervention strategies. This study highlights the critical role of tailored exercise programs in promoting active aging, improving functional capacity, and reducing healthcare burdens associated with fall-related injuries.

Introduction: Para-cycling is a competitive sport governed by the World Body for Cycling, Union Cycliste Internationale (UCI), encompassing various cycling disciplines tailored to athletes with physical or visual impairments. This study aimed to prospectively monitor the incidence of injury and illness in Para cyclists during the 2024 Paralympic season. Methods: This prospective, observational study included ten professional Para cyclists (five male, five female) with impairments ranging from spinal cord-related, neuromuscular, and musculoskeletal conditions to vision impairment. The definitions of an ‘athlete health problem’, ‘injury’, and ‘illnesses’ followed the Para sport translation of the IOC consensus. Injury and illness data were collected weekly using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems V2 (OSTRC-H2), with the addition of subjective markers of well-being and training load, between February 2024 and October 2024. All medical contacts for any injury or illness were logged in line with consensus statement recommendations. Results: The OSTRC-H2 questionnaire had a response rate of 76.5% (±12.2%, range 55–88%) across the 35 weeks. Athletes reported 7.36 (95% CI: 5.41–9.46) health problems per 365 days, with a medical attention rate of 5.56 (95% CI: 3.91–7.36) per 365 days. The overall injury rate was 1.94 per 365 athlete days (95% CI: 1.23–2.93), with a higher incidence in males (2.44, 95% CI: 1.53–3.67) than in females (1.51, 95% CI: 0.68–2.95). Conversely, illness rates were higher in females (5.40, 95% CI: 3.00–8.11) than in males (1.80, 95% CI: 0.60–3.30), with an overall illness rate of 3.60 per 365 days (95% CI: 2.29–5.10). Conclusions: This is the first study to present prospective injury and illness epidemiology rates in Para cyclists in combination with subjective well-being markers. The findings underscore the importance and feasibility of longitudinal health monitoring in Para cyclists, ensuring that both physical and mental health concerns are systematically tracked and addressed. This enables a proactive, multidisciplinary support system to respond effectively to fluctuations in well-being, particularly during periods of injury or illness. Full article

Squash, which originated in the early 19th century, was officially incorporated into the 2028 Los Angeles Olympic Games by the International Olympic Committee in 2023. This inclusion marks a significant milestone, highlighting its growing international recognition and potential for global development. However, squash has historically been underrepresented in academic research compared to other popular sports, with studies being scattered and relatively underdeveloped. To systematically evaluate the current state of squash research and foster academic development in the field, this study employs a combination of bibliometric and qualitative analyses, aiming to provide a comprehensive overview of squash research in terms of research progress, collaboration networks, key findings, and thematic evolution. Drawing on Web of Science, Scopus, and PubMed data, the analysis covers 206 publications from 36 countries spanning from 1973 to 2024. Network analysis based on co-authorship frequency and geographic clustering identifies the UK and Australia as leading contributors, with extensive collaboration among institutions and authors. Performance analysis (tactical and technical modeling), physiological profiling (energy demands), and medical studies (injury epidemiology) emerged as the three core research areas. The study reveals a shift in research focus from safety and physiological characteristics to performance enhancement, which is driven by technological innovation. Future research should prioritize underdeveloped areas such as youth development, psychology, and nutrition while integrating diverse participant groups (e.g., female athletes, recreational players) and advanced technologies.

Relevant skills and physiological traits vary between high-intensity functional training (HIFT) workouts, but it is unknown how altering each programming detail affects their importance. To examine the effect of workout duration on relationships to HIFT performance, twelve men and ten women with ≥2 years of HIFT experience (29.3 ± 7.1 years, 171 ± 7 cm, 80.5 ± 15.6 kg) completed a baseline visit to assess body composition and performance in vertical jump, barbell thruster, and 2000 m rowing tests. Participants returned twice to randomly complete the same circuit of rowing, barbell thrusters, and box jumps for “as many repetitions as possible” in 5 or 15 min. Performance was described by expressed kinetics on each exercise, overall and individual exercises, repetition completion rates and volume load completed, and transition times. Spearman correlation analysis revealed several expected relationships (p < 0.05) but also differences between workout durations. Performance measures, especially rowing (time: ρ = −0.89 to −0.94; power: ρ = 0.88 to 0.93), were more applicable to the 5 min workout. Experience and body composition measures (ρ = −0.47 to −0.50) were more often related to the 15 min transition strategy. These data suggest that increasing workout duration alters the importance of relevant predictive traits. Full article
