Mild cognitive impairment (MCI) is the transitional stage between normal cognition and dementia and is associated with arterial stiffness, which may lead to cardiovascular disease. A water-based exercise (W) presents a low-impact activity for the joints and increases resistance compared to exercises performed in the air, which benefits older adults. However, little evidence has been found regarding the effect of W on promoting cognitive and physical performance in older individuals with MCI. Therefore, this study aimed to investigate and compare the post-training effects of W alone and in combination with cognitive training on cognitive function, cardiovascular fitness, and arterial stiffness in older adults with MCI. Forty-six adults with MCI, aged 65 years or older, were enrolled. Participants were divided into two groups: a W group and a water-based exercise combined with cognitive training (W-COG) group. Both groups performed an aerobic exercise program in water for 60 min per/day, 3 day/week, for 12 weeks. Participants in the W-COG group simultaneously performed aerobic exercise and cognitive training in water. Cognitive performance, cardiovascular fitness, and arterial stiffness were examined before and after the intervention. The results revealed improvements in cognitive performance and cardiovascular fitness in both the W and W-COG groups after 12 weeks of intervention. However, there were no significant differences in cognitive and cardiovascular fitness changes between the two groups. Neither the W nor the W-COG groups showed a decrease in brachial pulse wave velocity. Therefore, W interventions have the potential to enhance cognitive function, restore cognition, and improve cardiovascular fitness in older adults with MCI. Full article

Background: Well-designed endurance training leads to improved cardiovascular fitness and sports performance in prolonged exercise tasks, with the adaptations depending on multiple factors, including the training modality and the population in question. It is still disputable how the type of training affects myocardial remodeling, and the information on myocardial remodeling by high-intensity interval training (HIIT) is particularly scarce. Methods: The current study investigated changes in cardiac structure after volume-progressive HIIT in running mode. As part of their conditioning program, amateur athletes (mean ± SD age of 18.2 ± 1.0 years) exclusively conducted HIIT in a volume-progressive fashion over 7 weeks (a total of 21 sessions). Peak oxygen uptake as well as 200 m and 2000 m running performance were measured, and transthoracic two-dimensional echocardiography was conducted before and after the intervention. Results: Training improved running performance, increased the peak oxygen uptake and left atrium diameter (from 32.0 ± 2.5 to 33.5 ± 2.3 mm; p = 0.01), and induced ~11% thickening of the left-ventricular posterior wall (7.5 ± 0.7 to 8.2 ± 0.4 mm; p = 0.01) and interventricular septum (7.6 ± 0.7 to 8.6 ± 0.9 mm; p = 0.02), but not the dilation of left-ventricular, right-ventricular, or right atrium chambers. Conclusions: HIIT of just 127 km of running per 8.5 h during 7 weeks was sufficient to improve aerobic capacity and running performance, and induce left-ventricular wall hypertrophy and left atrium dilation, in young healthy athletes.

There have been some studies investigating the effects of air pollutants on male football players, but few have examined the gender-specific impact of air pollution on the athletic performance of female football players. This research gap limits the development of tailored training and competition strategies. Here, generalized mixed modeling was employed to assess the effects of main ambient air pollutants, i.e., particulate matter less than 2.5 μm (PM_2.5), ozone (O₃), sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and carbon monoxide (CO), on athletic performance indicators (total movement distance (TMD), jogging distance (JD), and walking distance (WD)) among 14 female football players during 16 matches in the 2020 season of the Chinese Football Association Women’s Super League. Our findings indicate a significant negative association between the O₃ concentration and athletic performance, with fixed effect coefficients of −22.426 ± 8.889 for TMD, −10.817 ± 3.697 for JD, and −6.943 ± 3.265 for WD. The NO₂ concentration was significantly correlated with both TMD and JD, while PM_2.5, SO₂, and CO concentrations had minimal or negligible effects. Additionally, aerobic fitness was reduced as the O₃ concentration increased. These results provide valuable insights for optimizing gender-specific training and competition strategies under varying air quality conditions, offering a basis for more targeted health and performance interventions in professional female football players.

Cardiac rehabilitation should be suggested after mitral valve intervention. Physical exercise is associated with improved cardiorespiratory fitness and clinical outcome and reduced rehospitalization and mortality in patients after heart valve surgery. Tailored assessment is the first step before starting a cardiac rehabilitation program. Physical examination, electrocardiogram, echocardiography, and peak exercise capacity stratify the risk of these patients when prescribing appropriate supervised aerobic and resistance exercise training. Cardiac rehabilitation participation impacts physical capacity, psychosocial function, and prognosis in patients after mitral valve surgery and transcatheter edge-to-edge repair. However, further evidence is needed on the efficacy and safety of cardiac rehabilitation programs, as well as standardization. In this review, we provide a contemporary and comprehensive update on the role of cardiac rehabilitation in patients after mitral valve intervention, after both mitral valve surgery and transcatheter mitral valve implantation. Specifically, we focus our review on the tailored assessment and management of these patients from post-operative to cardiac rehabilitation. Full article

Background/Objectives: High-intensity interval training (HIIT) can optimize recovery by complementing the low cardiovascular fitness intensities typically achieved in stroke rehabilitation programs. Skating exercise is an HIIT workout developed based on ice skating movements, and we investigated the effects of this exercise on the cardiorespiratory fitness of elderly patients with minor stroke. Methods: Participants aged 65 or older with a National Institutes of Health Stroke Scale score of 3 or lower were recruited. This study was designed as a randomized controlled trial, in which the intervention group engaged in skating exercises following HIIT, while the control group underwent moderate-intensity continuous training (MICT). Both groups of participants performed either HIIT or MICT for 20 min per day, four times a week, over three months. Results: A total of 34 elderly patients with minor stroke were recruited, with an average age of 70.7 years. For three months, no fall-down injuries or adverse cardiovascular or cerebrovascular events were reported among patients undergoing HIIT or MICT. Both the intervention and control groups showed significant increases in the measures of aerobic capacity after the intervention. However, the patients in the intervention group exhibited significantly greater improvements in peak oxygen uptake, ventilatory threshold, and peak MET (p = 0.005, p = 0.002, and p = 0.024, respectively). Additionally, the Berg Balance Scale (BBS) scores and the skeletal muscle mass index showed significantly greater enhancements in the intervention group compared to the control group (p = 0.032 and p = 0.032). Conclusions: In conclusion, skating exercise could be a safe and effective HIIT protocol for elderly people who have experienced a minor stroke. Full article

Background/Objectives: Long-distance runners with exercise-induced hypertension (EIH) are at increased risk for cardiovascular complications. Although blood flow restriction (BFR) training has shown promise in improving vascular function, hemodynamic response, and cardiorespiratory fitness, its effects in EIH runners remain understudied. This study aimed to evaluate the effects of BFR training on cardiovascular responses and exercise performance in this population as a potential non-pharmacological therapy. Methods: Middle-aged male long-distance runners aged 40–65 with peak systolic blood pressure (SBP) ≥ 210 mmHg during graded exercise testing were randomly assigned to either a BFR group (n = 18) or a non-BFR control group (n = 15) using a computer-generated random sequence. There were no significant differences in baseline characteristics between the groups. Both groups performed aerobic training at 40–60% HRR for 20 min twice weekly for 8 weeks. SBP, diastolic blood pressure (DBP), rate pressure product (RPP), ventilatory threshold (VT), VO_₂max, and perceived exertion were assessed before and after the intervention at rest, during exercise, and during recovery. Results: Compared to the non-BFR group, the BFR group showed statistically significant reductions in resting and maximal SBP and DBP (p < 0.05), along with significant increases in VO_₂max and VT (p < 0.05). During submaximal exercise and post-exercise recovery, SBP and RPP were significantly lower in the BFR group (p < 0.05). The reductions in maximal SBP and DBP were significantly greater in the BFR group than in the control group. Conclusions: BFR training led to reduced myocardial workload and enhanced cardiovascular efficiency in male runners with EIH. These findings suggest that BFR training may be a viable non-pharmacological therapy for mitigating cardiovascular risks associated with EIH. Future studies should explore the long-term effects of BFR in broader populations and assess its applicability in clinical settings. Full article

Background: Cystic fibrosis (CF) is a chronic genetic disease marked by progressive lung function decline and increased respiratory infections. Emerging evidence supports the role of physical exercise in improving lung function, aerobic capacity, and quality of life in pediatric CF patients. Methods: We reviewed randomized clinical trials and observational studies from the last ten years, sourced from PubMed and Google Scholar. Included studies involved children and adolescents (0–18 years) with CF and assessed physical exercise as a primary intervention to improve lung function, aerobic fitness, quality of life, or hospitalization rates. Results: Aerobic training, particularly when combined with strength training, improves cardiorespiratory fitness and muscle strength without compromising nutritional status. High-Intensity Interval Training and Inspiratory Muscle Training show potential but need further validation. Supervised, personalized exercise programs are key to promoting adherence and optimizing outcomes. Conclusions: Exercise-based interventions in pediatric CF should evolve toward personalized, technology-enhanced, and sustainable models. Integrating wearable devices, adapting programs to individual needs, and leveraging early parental involvement may enhance engagement and outcomes, especially in the era of CFTR modulator therapies.

Background: Prehabilitation is increasingly being used in patients undergoing multimodality treatment for oesophagogastric cancer (OGC). Most studies to date have been small, single-centre trials. This collaborative study sought to assess the overall impact of prehabilitation on patient outcomes following OGC surgery. Methods: Data came from four prospective prehabilitation trials conducted in the UK or Ireland in patients undergoing multimodality treatment for OGC. The studies included three randomised and one non-randomised clinical trial, each comparing a prehabilitation intervention group to controls. The prehabilitation interventions included aerobic training delivered by exercise physiologists alongside dietetic input throughout the treatment pathway. The primary outcome was survival (all-cause and disease-specific mortality). Secondary outcomes were differences in complications, cardio-respiratory fitness (changes in VO_{2 peak} and anaerobic threshold (AT)), chemotherapy completion rates, hospital length of stay, changes in body mass index, tumour regression and complication rates of anastomotic leak and pneumonia. Cox and logistic regression analysis provided hazard ratios (HR) and odds ratios (OR), respectively, with 95% confidence intervals (CI), adjusted for confounders. Results: Among 165 patients included, 88 patients were in the prehabilitation group and 77 patients were in the control group. All-cause and disease-specific mortality were not improved by prehabilitation (HR 0.67 95% CI 0.21–2.12 and HR 0.82 95% CI 0.42–1.57, respectively). The prehabilitation group experienced fewer major complications (20% vs. 36%, p = 0.034; adjusted OR of 0.54; 95%CI 0.26–1.13). There was a mitigated decline in VO_2 peak following neo-adjuvant therapy (delta prehabilitation −1.07 mL/kg/min vs. control −2.74 mL/kg/min; p = 0.035) and chemotherapy completion rates were significantly higher following prehabilitation (90% vs. 73%; p = 0.016). Hospital length of stay (10 vs. 12 days, p = 0.402) and neoadjuvant chemotherapy response (Mandard 1–3 41% vs. 35%; p = 0.494) favoured prehabilitation, albeit not statistically significantly. Conclusion: Despite some limitations in terms of heterogeneity of study methodology, this study suggests a number of meaningful clinical benefits from prehabilitation before surgery for OGC patients. Current initiatives to agree on national standards for delivering prehabilitation and the results of ongoing trials will help to further refine this important intervention and expand the evidence base to support the widespread adoption and implementation of prehabilitation programs.

Objectives: This explorative study aimed to evaluate athletes’ perceptions of how CrossFit^® affects physical, psychological, and social well-being, exploring gender differences. CrossFit^® is a high-intensity functional training modality aimed at enhancing overall fitness and health. Limited research has explored its perceived impact on broader aspects of well-being, particularly considering gender differences. Methods: A total of 202 participants (age 34.3 ± 10.0 years) with at least 6 months of CrossFit^® experience completed an online self-reported questionnaire not previously published but created following published guidelines. The questions explore athletes’ perceptions of their improvements in physical fitness, injury occurrence, and the effects on mental well-being. Statistical analysis included descriptive statistics and parametric and non-parametric tests to investigate gender differences. Results: In total, 81.2% of participants perceived improvements in strength, while 83.2% reported enhanced aerobic capacity. Significant body composition improvements were noted by 68.3% of the sample, and 87.6% reported changes in eating habits. Injury incidence was lower among women (30.2%) than men (45.3%) (p = 0.02). Regarding psychological outcomes, 95% of respondents indicated a reduction in stress levels, 73.3% reported better sleep quality, and over 90% perceived improvements in self-esteem and daily energy. Furthermore, 98.5% of participants formed new social connections through CrossFit^®, with 79.2% acknowledging a positive impact on social relationships. No significant gender differences were found across most psychological and social outcomes. Conclusions: CrossFit^® is perceived positively by participants, with similar views across genders, except for injury rates. It enhances physical fitness, mental health, and social well-being, with high training adherence and relatively low injury risk. 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.

This study aims to evaluate the effects of a Walking Football (WF) programme on physical fitness, body composition, health-related quality of life (QoL), and happiness in men and women over 60 years. WF is proposed as a safe and accessible activity to counteract physical inactivity and chronic conditions in ageing populations. A randomized controlled trial will be conducted with 120 participants (both sexes), assigned to either an experimental group (WF intervention) or a wait-list control group. The six-month intervention includes bi-weekly sessions with skills training, match simulations, and fitness exercises. Assessments will be performed at baseline, 3 months, and 6 months. Primary outcome measures will be: body composition (weight, BMI, fat and lean mass), muscular strength, aerobic endurance, agility, range of motion, and subjective well-being (QoL and happiness scales). Linear mixed-effects models and ANCOVA will be used to analyse the data. It is expected that WF will lead to improvements in physical and mental health, contributing to active ageing. This study may also support WF as a tool for social inclusion and well-being in older adults. Full article

Background/Objectives: The majority of stroke survivors undergo physical therapy rehabilitation to regain functionality and improve their overall quality of life. Given the wide range of physical therapy modalities and approaches in post stroke cardiovascular fitness rehabilitation, this systematic review and meta-analysis (SR-MA) aims to assess their efficacy as measured by peak oxygen consumption (VO2peak). Methods: Adhering to PRISMA guidelines; a detailed search of the MEDLINE PubMed; Cochrane Library; and Scopus databases was conducted. Results: Thirty-seven studies with a total of 1310 post-stroke patients were included. The aggregated mean VO2 pre-intervention was 15.30 mL/kg/min ([14.09, 16.51], I² = 99.7%), increasing to 17.10 mL/kg/min post-intervention ([15.73, 18.46], I² = 99.8%). The standardized mean difference in VO2 was 1.76 ([1.20, 2.31], I² = 96.9%). Sensitivity analyses in a subset of RCTs revealed that cardiorespiratory rehabilitation demonstrates a statistically significant improvement in VO2peak levels compared to conventional physical therapy. There was a high degree of heterogeneity among included studies (potentially due to the lack of standardized protocols) while Egger’s test (β = 0.32, p = 0.72) and funnel plot inspection were indicative of moderate publication bias with small study effects. Conclusions: Based on the results of this meta-analysis, the increase in VO2peak levels post-interventions ranged from 0.28 to 3.36 mL/kg/min, depending on intervention type. The ideal time to commence aerobic training rehabilitation was found to be six months post-stroke. According to previous studies on cardiovascular diseases, VO2peak can potentially act as a predictor of (a) the efficacy of intervention and (b) the patient’s risk of stroke-recurrence and disability progression.

Objective: Strength training has gained recognition as an effective method to enhance physical fitness in children and adolescents. Its benefits include improvements in muscular strength, aerobic capacity (VO₂max), and motor performance. However, the diversity in training protocols and participant characteristics across studies necessitates a comprehensive synthesis of the evidence. The aim of this paper was to analyse the influence of a strength training programme in young people aged 6 to 16 years on different aspects of physical fitness. Methods: A search was carried out in the EBSCO, Web of Sciences, and Scopus databases. A total of 634 articles were reviewed, and 22 were finally included in the meta-analysis of articles published between 2013 and 2023 in English or Spanish. Twenty-two studies met the inclusion criteria and were assessed using the AXIS and PEDro tools. Standardised mean differences (SMD) and 95% confidence intervals (CI) were calculated. The variables that were most frequently repeated as criteria for evaluating the effectiveness of strength training were the following: (1) strength of the lower/upper body muscles; (2) VO₂max; (3) sprint performance. Results: Strength training interventions produced statistically significant improvements in all analysed variables. Most effective programmes lasted between 6 and 12 weeks, with 2–3 sessions per week. VO₂max showed the greatest improvement, followed by upper and lower limb strength, and sprint performance. Heterogeneity ranged from low to moderate. Conclusions: Supervised strength training programmes can significantly enhance physical fitness in school-aged children and adolescents. While the included studies varied in design and duration, measurable improvements were commonly observed in interventions lasting at least 6–8 weeks. Future research should explore age- and maturity-related responses through subgroup analyses. Limitations include the exclusion of studies published after 2023 and the wide age range of participants without biological stratification. Full article

(1) Background: Dynamic knee valgus (DKV) is a common biomechanical risk factor for knee injuries, particularly in sports involving high-intensity movements, such as basketball. While neuromuscular control and structural alignment contribute to DKV, recent evidence indicates that lower limb muscle power (LLMP) and cardiorespiratory fitness (CRF) may significantly influence DKV. This study aims to examine the relationship among LLMP, CRF, and DKV in adolescent basketball athletes. (2) Methods: A total of 104 adolescent basketball athletes (63.5% boys), 12 to 17 years old (13.87 ± 1.46 years) participated in this study. Anthropometric and demographic characteristics such as sex, age, height, weight, and body mass index (BMI) were recorded. The Counter Movement Jump (CMJ) was used for the evaluation and prediction of the LLMP, the 20 m shuttle run test (20mSRT) was used for the evaluation and prediction of CRF, and the single-leg drop jump (SLDJ) was used for the evaluation of DKV via a two-dimensional (2D) kinematic analysis. Statistical analysis included Pearson and Spearman correlations, as well as multiple linear regression, to determine the relationship among LLMP, CRF, and DKV. (3) Results: A statistical analysis revealed strong correlations among LLMP, CRF, and DKV. Pearson’s correlation coefficients demonstrated significant associations between the VO₂max and frontal plane projection angle (FPPA) (r = 0.78, p < 0.001), as well as between LLMP and FPPA (r = 0.82, p < 0.001). Multiple linear regression analysis showed that VO₂max and LLMP together accounted for 85% of the variance in FPPA (R² = 0.85, p < 0.001). (4) Conclusions: The findings highlight that both aerobic capacity and lower limb muscle power significantly contribute to knee valgus control among adolescent basketball players. Implementing training programs focused on improving lower limb muscle power and cardiorespiratory fitness may enhance knee stability and reduce the risk of lower limb injuries. Given the strong predictive value of VO₂max and LLMP for knee control, targeted training programs focusing on neuromuscular conditioning and aerobic capacity may be effective for injury prevention.

(1) Background: Individuals with obesity tend to stop exercising after the completion of a structured training program. Thus, the aim of the present study was to assess adherence and body composition, cardiorespiratory fitness, physical activity levels, and physical and mental health after a 12-month exercise program and an 18-month follow-up period in a group of male adults with obesity. (2) Methods: Thirty-four adults with obesity were evaluated before (T0) and after (T3) a 3-month combined training (COMB). After that, they followed a maintenance program with low-intensity aerobic activity for three months. Then, they were recalled for a 6-month training program including thresholds (THR) training until the end of the study (T12). Finally, they participated in a 18-months follow-up period that included suggestions for healthy lifestyles, which ended with assessments (T30). Thus, the assessments were carried out at the beginning and end of the first training protocol (T0 and T3), at the beginning and end of the second training protocol (T6 and T12) and 18 months after the end of the training program (T30). At all time points, body composition (i.e., BMI, fat mass [FM] and fat-free mass [FFM]), physical capacities (i.e., V̇O₂max), and physical habits (i.e., International Physical Activity Questionnaire (IPAQ) and Short-Form 12 (SF-12, for physical, P, and mental, M, indices) were measured. (3) Results: Fifteen out of thirty-four participants (42.8%) (age 42.8 ± 8.1 y) completed this study. At T30, participants increased their V̇O₂max (3.07 ± 0.46 vs. 3.67 ± 0.60 L·min⁻¹, p < 0.001), IPAQ TOT score (396 (2888) vs. 1356 (9144), p = 0.006), and SF12_MI score (41.1 ± 8.9 pt vs. 48.6 ± 11.0 pt) compared to T0. Furthermore, multivariate analysis showed that decrease in BMI was largely associated with the increase in the SF 12_PI questionnaire (0.032). Similarly, the decrease in %FM and the increase in V̇O₂max were related with the increase in IPAQ tot (p < 0.001) and SF 12_MI (p < 0.001) scores. (4) Conclusions: 42.8% (15 out of 34) of the initial participants completed the follow-up test at T30 and maintained higher V̇O₂max values than at T0. Conversely, their physical characteristics returned to baseline. The improvement in V̇O₂max, compared to T0, correlated with maintaining high activity levels and with improved physical and mental well-being. In summary, it is recommended that people with obesity follow a structured physical activity program, as this leads to an improvement in physical capacities and physical and mental well-being. A personalized and monitored approach can lead to greater adherence to treatment and more effective long-term outcomes. Full article
