Background/Objectives: There is limited empirical evidence on the feasibility of inclusive, community-based exercise programs for older adults with long-term mobility disabilities. This pilot study investigated the feasibility and preliminary effectiveness of a community-based high-intensity functional training (HIFT) intervention. Methods: This single-group pre–post feasibility trial was delivered across four community-based HIFT facilities. Thirteen participants enrolled, and 10 (mean age 69.8 ± 6.7 years; 60% female) completed baseline assessments, two onboarding sessions, and thrice-weekly group-based workouts across 16 weeks. Physical function was assessed using the Canadian Occupational Performance Measure (COPM), Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function, Modified Falls Efficacy Scale (MFES), and standardized tests of mobility, balance, and strength. Exploratory outcomes included body mass index (BMI), waist circumference, work capacity, and quality of life (QOL). Results: Recruitment, retention, and attendance rates were 38%, 77%, and 58% (80% including make-up sessions), respectively. The intervention was safe and well-tolerated, with one fall-related adverse event. Self-reported functional outcomes demonstrated small to large effects, with large improvements in participant-identified functional activities (d = 1.03–1.54) and fall efficacy (d = 0.97), and a small effect for standardized physical function (d = 0.36) Endurance improved substantially (d = 1.01), while mobility, balance, and strength outcomes reflected maintenance or small to moderate gains (d = 0.08–0.55). BMI remained stable (d = 0.05), work capacity increased with moderate to large effects (d = 0.61–1.43), and QOL improved modestly (d = 0.20). Exit interviews reinforced high acceptability, highlighting individualized adaptations, supportive trainers, and the group-based context as motivating contextual factors. Conclusions: A community-based HIFT program is feasible and acceptable for older adults with mobility disabilities. Full article

Objectives: Public safety personnel, such as police and firefighters, face high physical demands during emergencies, including compressions-only cardiopulmonary resuscitation (CPR) under fatigue. This study aimed to evaluate a High-Intensity Functional Training (HIFT) program, the Public Safety Heroes Workout (PUSH), designed to enhance emergency readiness. Methods: Fifteen active-duty public safety officers participated in a pilot study. The PUSH workout included tasks like sandbag carries and burpee box jumps, interspersed with chest compressions (CC). Physiological responses, including lactate levels, heart rate, and Compressions-only CPR quality, were measured. Results: The PUSH workout induced significant metabolic stress, with lactate levels rising from 2.2 to 14.8 mmol·L⁻¹. Heart rates peaked at 170 bpm, indicating high cardiovascular demand. Compressions-only CPR quality remained high, with firefighters outperforming police in compression rate. Conclusions: The PUSH workout effectively simulates the physical demands of emergency situations, enhancing readiness and compressions-only CPR performance under fatigue. This training model could be applied to other first responders and CrossFit^® athletes. Full article

Background/Objectives: This pilot study aimed to evaluate the feasibility of applying the Beers criteria in the community pharmacy setting and aid pharmacists in identifying and emphasizing adverse effects from potentially inappropriate medications (PIMs) for older adults. Methods: We applied a single-center retrospective study to collect demographic and outcome data in order to analyze dispensed PIMs for older adults. We used an evaluation tool to compare warnings between pharmacy dispensing software and the Beers criteria. Descriptive statistics were computed via standard statistical software. Results: Culled from a random selection of 215 patients, the medical records from 50 subjects ≥65 years old were reviewed, including 440 of their medications. Our data demonstrated that 96% of subjects were dispensed at least one PIM, with a total of 34 different PIMs distributed at varying frequencies. A comparative analysis indicated that 74% of dispensed medications had similar, but not identical, warning profiles presented in the dispensing software and Beers criteria. Anticholinergic burden of dispensed PIMs indicated that older adults were at risk of falls and delirium. By supplementing the dispensing software with Beers criteria, we were able to create clinical communication notes for providers, patients, and pharmacy students to emphasize the role pharmacists can play to minimize PIM’s adverse effects on older adults. Conclusions: Our data indicates the feasibility of implementing the Beers criteria in the community pharmacy setting. Integrating the dispensing software warnings with Beers criteria created a structured intervention strategy to prevent potential adverse effects and develop clinical communication notes to emphasize a more engaging role that the community pharmacy setting can play to optimize therapeutic outcomes for older adults.

Background: Wavelight technology (WT) has recently been introduced in international track meetings as a pacing aid designed to enhance consistency and performance. This study aimed to analyze the influence of WT on mean race speed and pacing profiles in 800 m Diamond League (DL) races and to compare its effects between men and women. Methods: Official results from 800 m DL races held between 2018 and 2025 (excluding 2020) were examined. A total of 689 performances (364 men, 325 women) were included, of which 403 used WT. Split times, each 200 mm, were extracted and expressed relative to mean race speed (%RS). WT implementation was confirmed through official race broadcasts. Results: Mean race speed differed significantly across years in both sexes (p < 0.001), with faster performances in 2024–2025 for men and in 2025 for women. In years where WT and non-WT races coexisted, WT was associated with higher mean speed in both men (7.60 ± 0.11 vs. 7.54 ± 0.14 m·s⁻¹; p = 0.007; small d = 0.47) and women (6.71 ± 0.09 vs. 6.67 ± 0.08 m·s⁻¹; p = 0.023; small d = 0.40). Regarding the pacing profiles, WT increased %RS in the first split (106.0 ± 1.7 vs. 104.9 ± 2.8; p = 0.014) and decreased it in the last split (96.5 ± 2.5 vs. 98.4 ± 4.4; p = 0.006) in men, whereas women showed no differences between conditions. Conclusions: WT was associated with faster mean race speeds in DL 800 m races and with more homogeneous pacing in men. However, WT modified pacing strategy only in men—inducing a faster start and slower finish—while women maintained similar pacing profiles regardless of WT use. WT thus enhances absolute performance but does not influence effort distribution equally across sexes. Full article

Background: Due to its high polyphenol content and purported capability to mitigate post-exercise muscle soreness and promote recovery, tart cherry (TC) supplementation has been proposed to enhance recovery and athletic performance. This study examined the effects of powdered TC supplementation on various recovery and performance metrics following a repeated sprint exercise protocol in physically active young adults. Methods: 40 (18 M, 22 F) healthy, active participants (24.6 ± 5.5 yrs, 171.5 ± 11 cm, 71.7 ± 14.5 kg, 24.2 ± 3.1 kg·m⁻²) participated in this randomized, double-blind, placebo-controlled, parallel study design. Placebo (PLA) or powdered TC supplementation (500 mg/day) occurred for ten days: seven days prior to, day of, and two days following repeated sprints (15 × 30 m with 1 min rest between sprints). Performance was assessed via the countermovement jump, isometric mid-thigh pull, isokinetic knee extension, and the Wingate anaerobic test. Recovery was evaluated using visual analog scales for soreness, recovery, and readiness to train. Muscle damage was evaluated using creatine kinase. These measures were evaluated at baseline, and at 1 h, 24 h, and 48 h post-exercise. Results: Significant main effects of time were observed with recovery VAS (p < 0.001), readiness to train VAS (p < 0.001), and jump height (p = 0.014) experiencing similar reductions, while soreness VAS (p < 0.001) and creatine kinase (p = 0.05) experienced similar increases in response to the repeated sprint protocol and supplementation. Across all measurements, no significant group × time differences were observed for jump height (PLA:−6.7 ± 10.4% vs. TC: −11.0 ± 17.9%, p = 0.608), peak propulsive force (PLA: 0.3 ± 4.6% vs. TC: 2.2 ± 7.4%, p = 0.194), knee extension peak torque at 180°/s (PLA: 10.5 ± 73.5% vs. TC: −1.04 ± 49.6%, p = 0.335), readiness to train VAS (PLA: −23.0 ± 19.2% vs. TC: −14.7 ± 20.2%, p = 0.401), soreness VAS (PLA: 250 ± 323% vs. TC: 261 ± 432%, p = 0.838), recovery VAS (PLA: −24.6 ± 17.9% vs. TC: −8.2 ± 40.5%, p = 0.251), and creatine kinase (PLA: 22.8 ± 35.5% vs. TC: 90.4 ± 225.6%, p = 0.31). Conclusions: A single bout of repeated sprints was responsible for significant reductions in jump height, peak propulsive force, peak torque, and perceived readiness, while perceived soreness, myoglobin, and creatine kinase were significantly increased. Ten days of TC supplementation did not impact any change beyond what was observed in PLA for markers of recovery, readiness, soreness, exercise performance, and markers of muscle damage.

Background: Trail running (TR) is an endurance discipline characterized by prolonged exercise, irregular terrain, and marked elevation changes, which increase eccentric muscular load and may induce muscular, neuromuscular, and cardiac damage. Objective: This study aimed to systematically review the evidence on muscular, neuromuscular, and cardiac damage associated with TR participation. Methods: This systematic review followed PRISMA 2020 guidelines and was registered in PROSPERO (CRD420251135043). Five databases (PubMed, Web of Science, Scopus, SportDiscus, and ScienceDirect) were searched up to 31 August 2025. Observational, longitudinal, prospective, and case studies involving healthy adolescent or adult trail runners were included. Outcomes comprised muscle damage biomarkers (e.g., creatine kinase, alanine aminotransferase), neuromuscular function (e.g., squat jump performance, maximal voluntary isometric contraction), and cardiac biomarkers (e.g., CK-MB, cardiac troponins, NT-proBNP). Methodological quality was assessed using the National Heart, Lung, and Blood Institute Study Quality Assessment Tool. Results were synthesized qualitatively. Results: Fifteen studies met the inclusion criteria, including a total of 247 participants. Post-race analyses consistently showed marked increases in muscle damage biomarkers and significant reductions in neuromuscular performance. Transient elevations in cardiac biomarkers were also observed, suggesting acute but reversible cardiac stress following TR events. Limitations: Evidence was limited by methodological heterogeneity, small sample sizes, and underrepresentation of female athletes. Conclusions: It was found that trail running induces substantial acute muscular, neuromuscular, and cardiac stress, particularly in events with high eccentric loading. Monitoring biochemical and neuromuscular markers may support training load optimization, recovery strategies, and injury prevention. Full article

Resilience to stress integrates cognitive, physiological, and behavioral adaptations to sustain performance under adversity. Genetic variation in catechol-O-methyltransferase (COMT, rs4680) and angiotensin-converting enzyme (ACE, rs1799752) modulates dopaminergic and renin–angiotensin signaling, influencing tissue oxygenation and fatigue resistance. We examined COMT- and ACE-promoter methylation and genotypes in relation to resilience traits in Swiss tactical athletes (24.6 years) with a maximal power output of 534 W and 21,656 W, respectively, during cardiopulmonary exercise and elbow strike testing. At a 5% false-discovery rate, COMT genotype/methylation explained ~12% of the variance in cognitive performance and metabolic resilience, while ACE explained ~6–7% in strength-endurance and muscle resistance. Antidromic linear associations between COMT genotype and methylation with visual reaction time under reactive stress indicate opposing regulatory influences, best captured by regression models incorporating (epi)genetic covariates. The strongest methylation effects involved COMT promoter associations with muscle hemoglobin content across cardiopulmonary exercise zones (r = 0.43–0.58) and sport-specific strain (r = −0.46). COMT- and ACE-promoter methylation, correlated with time spent in the first aerobic training zone (r = 0.55 and 0.32), indicating environmentally responsive epigenetic modulation. These findings highlight neurovascular–metabolic coupling via dopaminergic and renin–angiotensin pathways as a key mechanism in stress adaptation. System-level adaptations in these pathways align with COMT and ACE (epi)genetic blood profiles, positioning them as candidate resilience biomarkers. Larger, preregistered studies with site-specific CpG analyses and mechanistic assays are needed to establish causal relevance and translational utility for resilience-informed performance optimization in high-stakes professionals.

Background/Objectives: The dopaminergic system regulates motivation, executive functions, motor learning, and emotional responses—processes that are key in both sport and esports. Although many studies analyse dopaminergic gene polymorphisms, their impact on psychophysical predispositions remains unclear. This narrative review aims to summarise current knowledge about the mechanisms of dopamine action and genetic determinants that may influence athletic and cognitive performance. Methods: The PubMed, Scopus, and Web of Science databases (publications from January 2010 to December 2025) were searched using keywords related to the DRD1–DRD5, COMT, SLC6A3/DAT1, and TH genes, as well as the terms ‘sport’ and ‘esport.’ Studies of athletes were included in which the relationship between dopaminergic polymorphisms and motivational and personality traits was assessed, and the results of neuroimaging and epigenetic studies were also considered. Results: Dopaminergic polymorphisms are associated with differences in reward processing, cognitive flexibility, motivation, and stress resilience. The most essential critical effects concern the DRD2 and DRD4 variants, which are associated with novelty seeking, reward dependence, and coping with stress. The COMT Val158Met polymorphism affects dopamine levels in the prefrontal cortex, modulating executive functions. The effects of individual polymorphisms are moderate, and conclusions regarding esports remain speculative due to limited research in this area. Conclusions: Dopaminergic predispositions involve interactions among genetics, neural activity, and the environment. However, current evidence is limited by small sample sizes, a predominance of European populations, scarce data on esports players, and difficulties in separating genetic effects from training-related adaptations.

Background: Innovative training strategies aimed at improving physiological efficiency are of growing interest in kinesiology and sports performance. Elevation training masks (ETMs) offer a practical means of inducing hypoxia-like stress. However, evidence of their effectiveness in recreationally active populations remains limited. This pilot study examined the efficiency of a five-week progressive ETM protocol combined with high-intensity interval training (HIIT) in eliciting physiological, hematological, and body-composition adaptations relevant to endurance performance. Methods: Nine recreationally active men completed a five-week intervention consisting of three treadmill-based sessions per week: one weekly incremental Conconi test and two structured aerobic–anaerobic HIIT sessions performed with an ETM. Mask resistance was progressively increased to simulate altitudes of approximately 900–3600 m. Hematological variables (erythrocytes, hemoglobin, hematocrit, erythrocyte indices, leukocytes, and platelets), body composition, maximal heart rate (HRmax), and peripheral oxygen saturation (SpO₂) were assessed pre- and post intervention. Data were analyzed using paired-sample t-tests and repeated-measures ANOVA, with effect sizes reported (Cohen’s d, ω²). Results: A significant main effect of time on SpO₂ was observed (F(1, 8) = 130.61, p < 0.001, ω² = 0.69), along with a significant effect of training week (F(4, 32) = 17.41, p < 0.001, ω² = 0.43), and a significant Time × Week interaction (F(4, 32) = 15.20, p < 0.001, ω² = 0.42), indicating progressively greater post-exercise oxygen desaturation with increasing simulated altitude. Significant post-intervention increases were found in erythrocyte count, hemoglobin concentration, and hematocrit (p ≤ 0.009, d = 1.15–1.55), alongside increases in mean corpuscular volume and mean corpuscular hemoglobin. Platelet count increased significantly (p = 0.001, d = 1.68), while leukocyte values remained unchanged (p > 0.05). Body mass index (p = 0.049, d = 0.77) and body fat percentage (p = 0.012, d = 1.08) decreased following the intervention. HRmax tended to be lower at higher simulated altitudes. Conclusions: A five-week progressive ETM-HIIT protocol efficiently induced hematological and body-composition adaptations associated with improved oxygen transport and metabolic efficiency in recreationally active men. These findings support ETM-based training as an accessible strategy for enhancing physiological efficiency in endurance-oriented kinesiology practice, warranting confirmation in larger randomized controlled studies.

This study aimed to establish the concurrent validity and agreement of the K-power (KINVENT Biomecanique, Montpellier, France) hybrid sensor system that combines Ultra-Wideband and Inertial Measurement Unit measures against criterion timing gates for recording 20-m sprint performance in adolescent athletes. Fifteen trained adolescent track and field sprinters (age: 15.2 ± 2.4 years) performed two maximal 20-m sprints. Sprint times were simultaneously recorded using timing gates and the K-power sensor. Validity and agreement were assessed using paired-samples t-tests, Intraclass Correlation Coefficients (ICCs), Coefficient of Variation (CV), and Bland–Altman analysis. Sensitivity was determined by comparing the Typical Error (TE) to the Smallest Worthwhile Change (SWC). No significant systematic bias was observed between the devices (p > 0.05). The K-power sensor demonstrated excellent absolute agreement (ICC = 0.96, [95% CI = 0.94–0.98) and a low relative error (CV = 1.07%). The device displayed high sensitivity, with a TE (0.034 s) smaller than SWC (0.040 s). In conclusion, the K-power sensor is a valid and reliable instrument for measuring 20-m sprint times, being a practical alternative to timing gates. While the system is sensitive (TE < SWC), the Minimal Detectable Change of 0.094 s likely reflects the inherent biological variability of adolescent mechanics; thus, coaches should view changes exceeding 0.09 s as meaningful for individual athletes.

With the increasing competition in elite sports, pre-competition anxiety has become increasingly prevalent among high-level competitive athletes, and high levels of such anxiety may impair sports performance and threaten athletes’ psychological health. Traditional psychological interventions (e.g., cognitive-behavioral therapy) are often poorly accepted and costly; however, pre-competition anxiety in these athletes may be alleviated through multiple pathways of traditional mind–body exercises like Tai Chi. Yet, the psychological mechanism by which mind–body exercises such as Tai Chi training influence pre-competition anxiety remains insufficiently explored, particularly the chain-mediating effect of the “flow experience → mental toughness” pathway. This study thus aimed to investigate the impact of Tai Chi training on pre-competition anxiety in high-level competitive athletes and verify the chain-mediating role of the “flow experience → mental toughness” pathway, thereby providing a theoretical basis and practical reference for sports psychology interventions. Using a randomized controlled experimental design, 86 high-level competitive athletes were randomly divided into an experimental group (n = 43) and a control group (n = 43). The experimental group received standardized Tai Chi training for 8 weeks, while the control group maintained their regular training regimen. Data were collected at baseline, week 4, and week 8 of the intervention using the Competition State Anxiety Inventory-2 (CSAI-2), Flow State Scale-2 (FSS-2), and Sport Mental Toughness Questionnaire (SMTQ), and chain-mediating effects were tested via hierarchical regression analysis and the bootstrap method with 5000 resamples. The results indicated that Tai Chi training could reduce pre-competition anxiety levels (β = −0.30, p < 0.5), and both flow experience (β = 0.38, p < 0.5) and mental toughness (β = 0.21, p < 0.5) exerted significant mediating effects. The chain mediation model further revealed that Tai Chi training alleviated pre-competition anxiety by enhancing flow experience and improving mental toughness sequentially (β = 0.01, 95% CI [0.00, 0.03]), accounting for 78.9% of the total mediated effect. In conclusion, Tai Chi training is associated with reduced pre-competition anxiety in high-level competitive athletes, and this relationship is statistically mediated by the sequential pathway of flow experience and mental toughness. These findings offer a new theoretical basis and practical direction for mind–body interventions in sports psychology. It should be noted that future research could further optimize and refine the intervention protocol, and explore the underlying mechanism of mind–body interventions at the neurobiological level.

This study investigated the effects of 6 weeks of plyometric training (PT) performed on soft (unstable) and hard (stable) surfaces compared with conventional training on the balance, explosive power, and muscle strength of adolescent female basketball players. The participants were randomly assigned to three groups: soft-surface PT (n = 14), hard-surface PT (n = 14), and conventional training (n = 14). Performance outcomes included 30 m sprint time, vertical jump height, plantar flexion and dorsiflexion maximal voluntary isometric contraction (MVIC) torque, Y-balance dynamic balance, and center of pressure-based static balance. Ground reaction forces, MVIC torques, and balance parameters were measured using high-precision force sensors to ensure accurate quantification of biomechanical performance. Statistical analyses were performed using two-way repeated-measures ANOVA with post hoc comparisons to evaluate group × time interaction effects across all outcome variables. Results demonstrated that soft- and hard-surface PT significantly improved sprint performance, vertical jump height, and plantar flexion MVIC torque compared with conventional training, while dorsiflexion MVIC increased similarly across all the groups. Notably, soft-surface training elicited greater enhancements in vertical jump height, dynamic balance (posteromedial and posterolateral directions), and static balance under single- and double-leg eyes-closed conditions. The findings suggest that PT on an unstable surface provides unique advantages in optimizing neuromuscular control and postural stability beyond those achieved with stable-surface or conventional training. Thus, soft-surface PT may serve as an effective adjunct to traditional conditioning programs, enhancing sport-specific explosive power and balance. These results provide practical guidance for designing evidence-based and individualized training interventions to improve performance and reduce injury risk among adolescent female basketball athletes.

Background/Objectives: Swimming requires precise motor control, sustained attention, and optimal cognitive–motor integration, making it an ideal model for investigating neural efficiency—the phenomenon whereby expert performers achieve optimal outcomes with reduced neural resource expenditure, operationalized as lower activation, sparser connectivity, and enhanced functional integration. This systematic review examined cognitive performance and neural adaptations in swimming athletes, investigating neuroimaging and behavioral outcomes distinguishing swimmers from non-athletes across performance levels. Methods: Following PRISMA 2020 guidelines, seven databases were searched (1999–2024) for studies examining cognitive/neural outcomes in swimmers using neuroimaging or validated assessments. A total of 24 studies (neuroimaging: n = 9; behavioral: n = 15) met the inclusion criteria. Risk of bias assessment used adapted Cochrane RoB2 and Newcastle–Ottawa Scale criteria. Results: Neuroimaging modalities included EEG (n = 4), fMRI (n = 2), TMS (n = 1), and ERP (n = 2). Key associations identified included the following: (1) Neural Efficiency: elite swimmers showed sparser upper beta connectivity (35% fewer connections, d = 0.76, p = 0.040) and enhanced alpha rhythm intensity (p ≤ 0.01); (2) Cognitive Performance: superior attention, working memory, and executive control correlated with expertise (d = 0.69–1.31), with thalamo-sensorimotor functional connectivity explaining 41% of world ranking variance (r² = 0.41, p < 0.001); (3) Attention: external focus strategies improved performance in intermediate swimmers but showed inconsistent effects in experts; (4) Mental Fatigue: impaired performance in young adult swimmers (1.2% decrement, d = 0.13) but not master swimmers (p = 0.49); (5) Genetics: COMT Val158Met polymorphism associated with performance differences (p = 0.026). Effect sizes ranged from small to large, with Cohen’s d = 0.13–1.31. Conclusions: Swimming expertise is associated with specific neural and cognitive characteristics, including efficient brain connectivity and enhanced cognitive control. However, cross-sectional designs (88% of studies) and small samples (median n = 36; all studies underpowered) preclude causal inference. The lack of spatially quantitative synthesis and visualization of neuroimaging findings represents a methodological limitation of this review and the field. The findings suggest potential applications for talent identification, training optimization, and mental health promotion through swimming but require longitudinal validation and development of standardized swimmer brain atlases before definitive recommendations.

Background: Neoprene knee sleeves are commonly used to enhance joint stability and mechanical performance during resistance training. However, the specific influence of sleeve density on the force–velocity–power (F–V–P) profile during multi-joint lower-body exercises such as the back squat remains unclear. This study aimed to compare the theoretical F–V–P parameters derived from back squat performance while wearing low-density (LD) versus high-density (HD) knee sleeves. Methods: Fifteen resistance-trained males completed an incremental back squat test under both LD and HD conditions. A linear position transducer recorded barbell displacement and velocity. Individual force–velocity relationships were modelled to determine maximal theoretical force (F₀), velocity (V₀), power (Pmax), and the F–V slope. Paired-sample t-tests, linear mixed models, and Cohen’s d effect sizes were calculated. Clinical relevance was assessed using a threshold defined as 0.2 × the standard deviation of the HD condition. Bayesian analyses were conducted to estimate the probability and magnitude of the observed effects. Results: No statistically significant differences were observed between sleeve conditions for F₀, V₀, Pmax, or F–V slope (p > 0.05, d ≤ 0.37). Nonetheless, HD sleeves yielded slightly higher mean values for F₀, V₀, and Pmax, exceeding the predefined threshold for practical relevance. Bayesian models showed moderate probabilities (~0.80) that HD sleeves outperformed LD, though with limited chances of crossing the clinical significance threshold. Conclusions: Although HD sleeves do not produce systematic changes in F–V–P parameters, their increased material stiffness may provide small yet practically meaningful mechanical advantages in high-force resistance training contexts.

Background: CrossFit^® is a high-intensity functional training modality with increasing popularity, yet limited evidence describes the general profile of its practitioners. Objective: To characterize CrossFit^® athletes based on their training habits, injury prevalence, and nutritional supplement use, with specific consideration given to sex and age. Methods: An online questionnaire was completed by 358 practitioners (182 women; mean age 35.6 ± 9.1 years) from various Spanish regions. Descriptive and comparative analyses (χ² and ANOVA; p < 0.05) were conducted for training patterns, injury history, and supplement consumption. Results: Over half of the sample had practiced CrossFit^® for more than three years, typically training 3–4 days per week in one-hour sessions. Participants primarily reported social and health-related motivations and identified as non-competitive. Overall, 42.2% experienced at least one CrossFit^®-related injury, most frequently affecting the shoulder (15.6%) and lumbar spine (10.1%), largely attributed to repetitive overload. Supplement use was widespread (81.8%), with creatine (60.3%) and protein (49.4%) being the most commonly consumed. Conclusions: CrossFit^® practitioners train consistently, value the social environment, and show an injury pattern similar to that of other strength-based disciplines. Supplement consumption is highly prevalent across groups. Coaches and health professionals should prioritize injury-prevention strategies, promote safe load progression, and guide responsible supplement use. Full article
