Background: Thumb pain frequently arises from multiple conditions—de Quervain’s tenosynovitis, carpometacarpal (CMC) osteoarthritis, carpal tunnel syndrome, intersection syndrome, and myofascial pain syndrome—that often coexist yet are traditionally managed as separate entities. Fascial abnormalities, including hyaluronic acid-related densification and impaired interlayer gliding, have been proposed to constitute a shared pathological substrate underlying these conditions. Ultrasound-guided fascia hydrorelease (US-FHR) targeting fascial pathology has been used clinically for thumb–wrist pain; however, the anatomical targets and treatment regions have not been systematically described. Aim: This article presents a fifteen-point US-FHR clinical protocol for five converging thumb pain conditions, based on shared fascial abnormalities—densification and impaired interlayer gliding—that these conditions may have in common. It further provides a shared practical framework for pain physicians, orthopedic specialists, hand therapists, and acupuncturists. Methods: The protocol was organized based on a focused literature review on fascial biology, thumb–wrist anatomy, and the five converging conditions, combined with long-term clinical experience at Kimura Pain Clinic. For each POINT, the anatomical rationale, associated pain pattern, procedural concept, and major safety considerations were summarized. A four-direction screening test (thumb flexion, extension, abduction, and adduction) assessed in three modes (active contraction, resistance loading, and passive stretch), combined with nine established clinical tests, was integrated to identify the affected fascial structures. A diagnostic ultrasound finding characterized by multi-layered hyperechoic bands with reduced interlayer gliding—the sonographic appearance termed “stacking fascia” (a hyperechoic, stripe-shaped lesion), a previously described morphological sign that may reflect fascial densification—is described. Results: The protocol comprises 15 POINTs distributed across two approaches: nine POINTs via a dorsal approach and six POINTs via a palmar approach. The dorsal approach (9 POINTs) covers the first and third extensor compartments, their intersections (1st–2nd and 2nd–3rd), the two radial-artery crossing points (Points 5 and 6, where the radial artery passes deep to the first-compartment and EPL/ECRB–ECRL tendons, respectively), Gokoku (Hegu), the adductor pollicis, and the deep palmar arch. The palmar approach (6 POINTs) covers the thenar muscles, transverse carpal ligament, paraneural sheath and interfascicular epineurium of the median nerve, the median-nerve/FPL/FCR interface, the median nerve within the carpal tunnel, and the deeper palmar ligamentous structures adjacent to the median nerve. Periarterial release around the radial artery is proposed as a hypothesis-generating approach to CMC osteoarthritis, in which fascial constriction of periarterial tissue may contribute to subchondral vascular compromise. For each POINT, the anatomical rationale, associated pain patterns, procedural concept, and safety considerations are integrated and described. Conclusions: The proposed fifteen-point protocol represents an expanded, structured, and clinical-experience-based framework for US-FHR in five converging thumb pain conditions sharing common fascial abnormalities. It may serve as a practical basis for the standardization, education, and broader dissemination of US-FHR in this population. Prospective observational studies, randomized controlled trials, and imaging validation studies are needed to evaluate its clinical effectiveness and to test the underlying mechanistic hypotheses, including potential periarterial vascular contributions to CMC osteoarthritis.

The cerebellum plays a key role in regulating movement, coordination, and certain cognitive functions. Purkinje cells are the principal neurons of the cerebellum, essential for integrating information and modulating output to other parts of the central nervous system. Physical exercise is crucial for maintaining psychophysical well-being and improving quality of life. Moreover, its beneficial effects on brain health are well established. After a brief overview of cerebellar anatomy, this narrative review aims to summarize current experimental evidence on the effects of physical activity on Purkinje cells, particularly in the context of neuronal plasticity and neuroprotection. Special attention is given to structural and functional adaptations under both physiological and pathological conditions, including neurodegenerative diseases, neurodevelopmental disorders, traumatic brain injury, and aging. Overall, the available findings suggest that Purkinje cells represent a key cellular target of exercise-induced cerebellar plasticity. Physical activity may therefore contribute to preserving cerebellar function and promoting neuroprotection through mechanisms involving structural remodeling and synaptic adaptation of Purkinje cells.

Objectives: Sided games are commonly used to condition players for the demands of official games (OGs). Therefore, this study aimed to evaluate if different sided games match position-specific locomotor and mechanical OG demands of professional football players. Methods: Twenty-one male professional football players from a second team of a professional football club were monitored during the second half of the 2024/25 season. External load was assessed during OGs and sided games. The latter were categorized by area per player (ApP) as small- (SSG, ApP < 100 m²), medium- (MSG, ApP 100–200 m²) and large-sided games (LSG, ApP > 200 m²). External load was analyzed for total distance (TD), high-speed running (HSR), sprint distance (SPD), and the number of accelerations (ACC) and decelerations (DEC). Players were grouped by position: center backs (CBs), full backs (FBs), central midfielders (CMs), wide midfielders (WMs), and strikers (STs). Results: Across all playing positions (CB, FB, CM, WM, ST), SSGs, MSGs and LSGs elicited significantly higher TD than the OG, except for CM, where no significant differences were observed during SSGs and LSGs. All positions displayed similar HSR during LSGs than OG demands, and some positions also during MSGs (CB, CM, FB) and SSGs (CB). SPD was similar across all positions only during LSGs. ACC and DEC were significantly higher for all positions in SSGs and MSGs than OGs and similar in LSGs. Conclusions: Position-specific OG demands were not statistically from different sided-game formats. ACC, DEC and TD in LSGs met OG demands; however, smaller formats (SSGs, MSGs) overload those variables. In contrast, HSR and SPR load in SSGs and MSGs did not meet OG demands for most positions. For that, coaches should use LSGs, knowing that TD may be overloaded, or supplement SSGs/MSGs with running-based drills for more accurate programming. Full article

Background: SARS-CoV-2 infection may impair functional capacity in athletes, while prior vaccination status may be associated with post-infection functional status. However, evidence comparing objective post-infection exercise responses according to vaccination status in elite athletes remains limited. Methods: This study included a total of 220 male athletes with PCR-confirmed SARS-CoV-2 infections: 101 unvaccinated and 119 vaccinated with two doses prior to infection. Cardiopulmonary exercise testing (CPET) was performed 14 ± 1 days after confirmation of SARS-CoV-2 infection and before the athletes returned to full training. A two-way ANOVA was conducted for each CPET variable, using vaccination status and sport as fixed factors. Results: After accounting for the type of sport, vaccinated athletes showed significantly higher VO₂max, VO₂ at VT1, oxygen pulse, heart rate at VT1, and heart rate at VT2, as well as lower VE/VCO₂ values. No significant differences were found for VEmax, HRmax, or heart rate during recovery. The interaction between vaccination status and sport was not significant for the main CPET outcomes, indicating a similar pattern in both sports. Conclusions: These findings suggest that prior vaccination is associated with a more favorable early post-infection physiological profile in professional team-sport players. Full article

Heart rate variability (HRV) monitoring is commonly used in sport and exercise science to assess recovery, training adaptation, and performance readiness. However, the routine reporting of numerous HRV metrics with substantial conceptual and physiological overlap has created inconsistency regarding which indices should be prioritized for applied monitoring. This narrative review synthesizes the contemporary literature to provide practical recommendations regarding HRV metric selection in applied monitoring, with particular emphasis on whether the root mean square of successive differences between adjacent normal-to-normal intervals (RMSSD) may serve as the primary metric for routine HRV monitoring in many healthy sport and exercise populations. RMSSD demonstrates several characteristics favorable for applied monitoring, including strong physiological relevance, favorable reliability, compatibility with ultra-short recording durations, relative robustness during spontaneous breathing, computational simplicity, and suitability for longitudinal monitoring frameworks. Although additional HRV metrics remain valuable for addressing specific physiological, mechanistic, or research questions, the current evidence supports RMSSD as the primary metric for routine HRV monitoring in many sport and exercise settings.

Background: Motor competence is an important basis for early childhood motor development and for the acquisition of new motor skills. Previous work from this research perspective showed that structured kindergarten kinesiology programs and overall BOT-2 motor proficiency are associated with phase-based motor learning outcomes. However, it remains unclear whether individual motor competence components are related differently to distinct phases of early motor learning. The aim of this study was to examine associations between selected BOT-2 motor competence components and phase-based motor learning outcomes in preschool children. Methods: A total of 161 preschool children participated in the study. Selected BOT-2 components were used to describe baseline motor competence. Motor learning was assessed using a standardized 7-week protocol involving previously unfamiliar kinesiology tasks and was operationalized through time to initial acquisition (F1), time to early refinement (F2), and final performance quality (K). Correlation analyses and hierarchical regression models were used, controlling for age, sex, and previous participation experience. Results: Motor competence components were positively interrelated and were significantly associated with learning outcomes. Higher baseline motor competence was generally associated with shorter F1 and F2 times and higher K scores. Participation experience showed the largest and most consistent associations across outcomes. Fine motor precision was independently associated with F1 and F2, while running speed and agility was retained as a predictor of F2. Conclusions: The findings indicate that previous structured movement experience and selected motor competence components are associated with phase-based motor learning outcomes in preschool children. These results should be interpreted as associative rather than causal and support the use of assessment-informed approaches in early childhood kinesiology programs. Full article

Objectives: External load demands (ELD) for junior basketball players have primarily been investigated in senior championships, although the competition level influences the players’ performance. The purpose of this study was to determine the between-quarter and between-position differences for U19 basketball players in their age-related championship throughout a whole competitive season. Methods: Data were collected from fifteen Hungarian U19 basketball players across eight home games via the WIMU PRO^TM local positioning system (Hudl, Nebraska, United States of America). Linear mixed models were used to evaluate omnibus main effects and position × quarter interactions for high-intensity accelerations (HIA), decelerations (HID), Player Load (PL), and vertical jumps (JUM), using Bonferroni adjustments and exploratory simple comparisons (p < 0.05). Moreover, model-based mean differences (MBMM) were also calculated with 95% confidence intervals (CI). Results: Significant game quarter omnibus main effect (F = 2.836, p = 0.043) and a borderline position × quarter interaction (F = 2.184, p = 0.050) were found in the JUM metric, with exploratory analyses revealing significant differences for centers between the second and third quarters and between the third and fourth quarters (p = 0.004, Mean Difference = −0.196, 95% CI = −0.345 to −0.046; p = 0.003, Mean Difference = 0.194, 95% CI = 0.049 to 0.338, respectively). A significant positional omnibus main effect (F = 4.917, p = 0.025) and a non-significant position × quarter interaction (F = 0.570, p = 0.753) was found for HID, with a significant difference between guards and forwards in the second quarter (p = 0.036, Mean Difference = 0.389, 95% CI = 0.019 to 0.742). PL and HIA did not show any significant differences. Conclusions: It is concluded that for the investigated sample, certain positional external load demands fluctuate between-quarter and between-position indicating that specific drills should be designed to maximize players’ performance and minimize their risk of injury. However, our results cannot be generalized due to the specificity of our dataset. Full article

Objective: To investigate the effects of short-term ginger supplementation on physical performance, perceived exertion, and neuromuscular fatigue in CrossFit^® practitioners. Methods: Thirty-two CrossFit^® practitioners were randomly assigned to a Ginger group (n = 17) or a Placebo group (n = 15) in a randomized, double-blind, placebo-controlled trial. Participants consumed 2 g·day⁻¹ of ginger or placebo for 9 days. Performance was assessed using a 10 min As Many Repetitions As Possible (AMRAP) test. Ratings of perceived exertion (RPE) and countermovement jump (CMJ) variables were evaluated before and after exercise. Results: Ginger supplementation significantly improved AMRAP performance compared with placebo (241.6 ± 18.2 vs. 225.9 ± 17.5 repetitions; F_1,29 = 5.95, p = 0.021, ηp² = 0.17). Participants in the Ginger group also reported lower RPE values (F_1,29 = 24.11, p ≤ 0.001, ηp² = 0.45). Regarding neuromuscular fatigue, ginger attenuated the decline in CMJ peak force following exercise (F_1,29 = 6.62, p = 0.015, ηp² = 0.18). No significant between-group differences were found for peak power and center of mass displacement. Conclusions: Short-term ginger supplementation improved AMRAP performance, reduced perceived exertion, and attenuated the decline in peak force following exercise in CrossFit^® practitioners. These findings suggest that ginger supplementation may have potential as a natural ergogenic strategy for high-intensity functional exercise; however, further studies with larger samples are needed to confirm these effects.

Background: Pre-season physical monitoring may help coaches understand short-term changes in youth soccer players and examine whether physical indicators are associated with early squad inclusion. This study aimed to analyze changes in physical performance during the pre-season period and to examine whether pre- and post-assessment physical performance differed between squad-included and non-included under-15 male soccer players in the first five official matches of the main competition. Methods: Thirty-seven male outfield players were assessed using the Squat Jump (SJ), Countermovement Jump (CMJ), 20 m linear sprint (Sprint-20 m), 20 m change-in-direction test (COD-20m), and Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IRL1). Squad-included players were those listed in at least one of the first five official match reports, whereas non-included players were not listed in these reports but remained part of the broader under-15 program. Results: Significant increases were observed in SJ (+1.44 cm, p = 0.007), CMJ (+1.36 cm, p = 0.006), and COD-20m (+0.38 km·h⁻¹, p = 0.002), whereas Sprint-20 m and Yo-Yo IRL1 did not change significantly. Fourteen players were squad-included and 23 were non-included. Squad-included players presented higher pre-assessment values for SJ, CMJ, COD-20m, and the exploratory composite physical score, and higher post-assessment values for SJ, CMJ, Sprint-20 m, COD-20m, and the exploratory composite physical score. The largest between-group difference was observed for post-assessment COD-20m (14.19 ± 0.49 vs. 13.40 ± 0.74 km·h⁻¹, p < 0.001, d = 1.25). Conclusions: Early squad inclusion was associated with higher absolute physical performance, particularly post-assessment COD-20m, whereas the magnitude of pre-to-post changes was not clearly associated with squad inclusion.

Background: Sports training induces functional and structural adaptations that may influence body composition, particularly during adolescence when growth and maturation are still occurring. Although anthropometric characteristics have been extensively studied within individual sports, comparative analyses among different sport categories remain limited. The aim of this study was to compare body composition characteristics among athletes participating in individual, team, and combat sports within a Spanish Sports Technification Program. Methods: A total of 118 young athletes (62 males and 56 females) from the Valencian Sports Technification Centre participated in this cross-sectional study. Participants were classified into three sport categories: individual sports (athletics, swimming, and triathlon), team sports (handball and volleyball), and combat sports (karate and taekwondo). Anthropometric assessment was performed according to the International Society for the Advancement of Kinanthropometry (ISAK) protocol. Body composition variables, including fat mass, muscle mass, and bone mass, were estimated using established anthropometric equations. Statistical analyses were performed using non-parametric tests, with significance set at p < 0.05. Results: After adjustment for multiple comparisons, significant differences remained between sport categories for several body composition indicators. Athletes from the individual sport group showed a higher muscle mass percentage and lower body fat percentages estimated using the Withers, Faulkner, and Carter equations than those from the team sport group. Similarly, estimated body fat percentages were lower in the individual sport group than in the combat sport group across all three equations. Team sport athletes presented higher absolute fat and muscle mass than combat sport athletes. However, some differences identified in the initial analyses, including fat mass and bone mass percentage between the individual and team sport groups and muscle mass percentage between the team and combat sport groups, did not remain statistically significant after adjustment for multiple comparisons. Conclusions: Body composition characteristics differed among the groups of young athletes participating in the specific individual, team, and combat sports included in this study. Within this cohort, athletes from the individual sport group generally exhibited lower body fat levels than those from the team and combat sport groups, whereas differences were also observed in other anthropometric characteristics. These findings should be interpreted within the context of the specific sports included and should not be generalized to individual, team, or combat sports as a whole. The findings may assist coaches, sports scientists, and health professionals in the monitoring and development of young athletes participating in similar sports and development programs.

Background: Low-load resistance exercise with blood flow restriction (BFR) may increase neuromuscular stimulation while reducing external load. This pilot study examined the acute effects of unilateral knee extension at 20% one-repetition maximum (1RM) with BFR at 80% estimated arterial occlusion pressure (AOP), compared with the same protocol without BFR, on vastus lateralis surface electromyographic (sEMG) activity in healthy young adults. Methods: Twenty participants were randomized to receive BFR on either the dominant (n = 10) or non-dominant limb (n = 10); the contralateral limb completed the non-BFR condition. Both conditions were performed in randomized order during one session, separated by 10 min. Each limb completed 75 repetitions (30-15-15-15) at 20% of its limb-specific 1RM. The prespecified primary outcome was normalized RMS amplitude across 12 protocol windows, analyzed using a linear mixed model. Results: Normalized RMS amplitude was higher under BFR (between-condition difference, 21.12%MVIC; 95% CI, 14.54 to 27.71; p < 0.001). Exploratory analyses showed higher global mean and peak RMS under BFR, whereas within-protocol RMS change and temporal slope did not differ. The post-exercise percentage reduction in MVIC-derived RMS amplitude was smaller under BFR (−0.6 ± 14.1% vs. −15.4 ± 12.3%; p = 0.002). Significant secondary findings remained significant after Holm adjustment. No adverse events were spontaneously reported or observed immediately. Conclusions: Under this acute laboratory protocol, individualized BFR was associated with higher vastus lateralis sEMG amplitude than unrestricted exercise. MVIC-derived findings were exploratory and should not be interpreted as evidence of preserved strength or reduced neuromuscular fatigue. Larger studies, including clinical populations, are required.

Objectives: This study aimed to examine the effects of three different warm-up protocols on performance, physiological, and perceptual responses in high-level water polo players. Methods: Ten international-level athletes (Tier 4; mean ± SD: age 22.4 ± 3.53 years; height 1.78 ± 0.06 m; body mass 75.83 ± 6.44 kg) completed three experimental conditions in a randomized, counterbalanced design: dryland, in-water, and combined warm-up. Following each warm-up condition, participants performed the Water Polo Intermittent Shuttle Test (WIST), while performance (distance covered and average speed), blood lactate concentration ([La⁻]), heart rate (HR), tympanic temperature, and rating of perceived exertion (RPE) were assessed. Statistical significance was set at p ≤ 0.05. Results: Players covered greater distances following the in-water (331.5 ± 151.24 m) and combined (358.5 ± 134.06 m) warm-ups compared to dryland (226.5 ± 129.51 m; p < 0.01; ES = 2.00 and 1.53, respectively), with no significant differences between in-water and combined conditions (p = 0.381; ES = 0.29). Physiological responses following the WIST were largely similar between conditions, although [La⁻] was higher in the dryland condition (12.46 ± 4.46 mmol·L⁻¹) compared to the combined condition at 10 min post-exercise (8.66 ± 2.47 mmol·L⁻¹; p = 0.03; ES = 0.80). No differences were found for HR, tympanic temperature, or RPE. Conclusions: These findings suggest that warm-up protocols including an in-water component are more effective than dryland-only routines for optimizing intermittent performance in water polo players. However, combining dryland and in-water exercises does not appear to provide additional benefits compared to in-water warm-up alone. Full article

Background: Futsal is a high-intensity, intermittent team sport, yet laboratory protocols that reproduce its substitution-based running demands remain scarce. This study examined the physiological, neuromuscular, and perceptual responses to the Futsal Intermittent Treadmill Protocol (FITP), a laboratory-based protocol designed to replicate the intermittent high-intensity running demands of futsal. Methods: Ten male, national-level (Tier 3) futsal players completed four bouts of intermittent running (6–20 km·h⁻¹) reflecting typical substitution patterns. Measurements included oxygen consumption (VO₂), heart rate (HR), blood lactate concentration ([BLa⁻]), rating of perceived exertion (RPE), total quality recovery (TQR), and countermovement jump (CMJ) performance. Responses were analyzed using one-way repeated-measures ANOVA. Results: HR and %HRmax increased significantly across bouts (p < 0.001; η²p = 0.84 for both), reaching values typical of competitive matches. Relative VO₂ and %VO₂max remained stable, while RPE increased and TQR decreased progressively (p < 0.001; η²p = 0.59–0.62). Blood lactate levels and the CMJ mechanical variables showed no significant changes, indicating no systematic neuromuscular fatigue pattern. Conclusions: The FITP induces substantial cardiovascular and perceptual strain that is physiologically comparable to high-intensity futsal, while metabolic and neuromuscular responses remain stable. The protocol may provide a controlled, repeatable method for assessing intermittent running tolerance; however, optimizing its role in physical evaluation, top-up conditioning, and return-to-play monitoring will benefit from future research confirming its ongoing consistency and field application.

Background: This study aimed to compare changes in motor coordination associated with two different motor practice models—multisport and single-sport soccer training—in children, without implying causal effects of one training context over the other. Methods: A quasi-experimental pre–post study (T0–T1) was conducted over 10 weeks in non-randomized, pre-existing groups. A total of 143 children (mean age: 6.21 ± 0.55 years; 107 males) were allocated to a Multisport Group (MG; n = 79) and a Single-sport Group (SG; n = 64). Motor coordination was assessed using the Körperkoordinationstest für Kinder (KTK), and raw scores (RAW SCORE) were used for analysis. Statistical analyses included t-tests, change-score (Δ) and effect-size analyses, and two-way repeated-measures ANOVA. Results: Both groups showed significant improvements over time (p < 0.001; d = 0.75 for MG, d = 0.77 for SG). However, the MG showed significantly greater improvements than the SG (Δ = 16.68 ± 6.14 vs. 12.28 ± 4.08; p < 0.001; d = 0.83). At T1, the SG still showed slightly higher absolute RAW SCORE values than the MG (p = 0.049; d = −0.33), although this between-group difference was markedly reduced compared to baseline (d = −0.59). The ANOVA revealed a very large effect of Time (F(1,141) = 1092.31, p < 0.001, η²p = 0.886), a small-to-medium effect of Group (F(1,141) = 7.51, p = 0.007, η²p = 0.051), and a large Time × Group interaction (F(1,141) = 24.18, p < 0.001, η²p = 0.146). A sensitivity analysis (ANCOVA) confirmed that, after adjusting for baseline scores, sex, and anthropometric variables, the Multisport group showed significantly higher adjusted T1 scores than the Single-sport group (adjusted mean difference = 3.96 points, 95% CI: 1.93–5.99), reversing the direction observed in the unadjusted T1 comparison. Given the non-randomized design and baseline group differences, findings reflect observed associations rather than causal effects. Conclusions: Both practice models were associated with improved motor coordination, with multisport participation associated with greater observed change over 10 weeks. These findings are consistent with a possible role of diversified motor experiences in coordination development, though this study cannot establish causality. Full article

Background: Rotator cuff tendinopathy is a common musculoskeletal disorder associated with shoulder pain, functional limitations, and reduced quality of life. A wide range of non-surgical interventions have been investigated, and uncertainty remains regarding their comparative effectiveness. Objective: This study aimed to summarize recent evidence on non-surgical treatments for rotator cuff tendinopathy and evaluate their reported clinical outcomes. Methods: A structured narrative review was conducted using Google Scholar to identify studies published between 2020 and 2025 involving adult patients with rotator cuff tendinopathy. Studies investigating exercise therapy, platelet-rich plasma (PRP), extracorporeal shockwave therapy (ESWT), laser therapy, kinesiotaping, and percutaneous electrolysis were considered. Following screening and eligibility assessment, 21 studies met the inclusion criteria. Results: Exercise therapy was the most extensively investigated intervention and consistently improved pain, function, and shoulder mobility. PRP injections were associated with favorable effects on pain and functional outcomes, although treatment protocols varied substantially. Several studies reported improvements following ESWT in pain reduction and functional recovery. Evidence from a limited number of studies suggests that high-power laser therapy may improve clinical outcomes, whereas evidence supporting low-level laser therapy remained inconclusive. Kinesiotaping and percutaneous electrolysis demonstrated potential benefits, although the available evidence remains limited. Conclusions: Exercise therapy remains the cornerstone of conservative management for rotator cuff tendinopathy. Adjunctive interventions, including PRP, extracorporeal shockwave therapy, and high-power laser therapy, may provide additional benefits in appropriately selected patients. However, methodological heterogeneity and differences in treatment mechanisms limit direct comparisons between modalities. Full article

Background: This study investigates the psychophysiological stress profiles of professional basketball players by simultaneously analyzing two distinct neuroendocrine pathways: the sympathetic–adrenal–medullary (SAM) system, via salivary alpha-amylase (AA), and the hypothalamic–pituitary–adrenal (HPA) axis, via salivary cortisol (C). While competitive environments are known to elicit significant stress, the interaction between game-specific variables—such as playing time (PT) and tactical position—and those biomarkers remains insufficiently explored in real-time, official match settings. Methods: Twelve professional male basketball players were monitored across four official matches. Salivary samples were collected, and stress biomarkers (AA and C) were analyzed at three timepoints: pre-match, half-time, and post-match. Results: Results indicate that stress responses are non-uniform and highly context-dependent. A significant spike in AA was observed during the first match (p < 0.001; ES = 0.82; 95% CI −0.01–1.66), where concentrations rose from a pre-match mean of 247.9 ± 232.59 U/mL to a post-match peak of 674.39 ± 693.33 U/mL. Cortisol responses did not vary significantly across matches but exhibited a strong positive correlation with PT (p = 0.01; R = 0.76), identifying that C may serve as a primary marker of individual physical workload. Positional analysis revealed significant divergence in HPA activation; guards (0.55 ± 0.31 µg/dL) and centers (0.51 ± 0.22 µg/dL) exhibited higher cortisol levels compared to forwards (0.24 ± 0.18 µg/dL), reflecting the high cognitive/decision-making load of guards and the mechanical/physical contact load of centers. Conclusions: The observed differences in AA and C liberation suggest that stress responses during matches are influenced by a complex interaction of physiological and psychological stimuli characteristic of competitive basketball. Consequently, these findings indicate the importance and value of a dual-biomarker approach which might provide a framework for optimized training load management and recovery protocols in elite basketball.

Background: East African runners, particularly from Kenya, have long dominated long-distance running, whereas highly trained European runners represent an appropriate comparison population to investigate structural and potentially modifiable anthropometric characteristics. Objective: To compare structural and modifiable anthropometric traits between professional Kenyan and European long-distance runners and to investigate the relationship between local muscularity and skeletal robustness. Methods: A total of 52 male marathon runners (32 Kenyan and 20 European) were assessed according to the International Society for the Advancement of Kinanthropometry (ISAK) protocol. Participants were 27.2 ± 5.2 years with a BMI of 18.4 ± 1.1 kg·m⁻² and a marathon time of 02:09:26 in the Kenyan group, and 30.9 ± 4.9 years, BMI 21.1 ± 2.1 kg·m⁻², and marathon time of 02:18:31 in the European group. Corrected girths were calculated to explore correlations between skeletal breadths and muscularity. Results: European runners exhibited significantly greater body mass, sitting height, girths, skeletal breadths, and muscle mass compared to Kenyan runners (p < 0.05), with large to very large effect sizes. In contrast, Kenyan runners showed lower adiposity and more linear body proportions, including a lower Cormic index and higher intermembral index. Differences in segment lengths were generally limited. Principal component analysis showed clearer group separation for modifiable than structural traits. Significant positive correlations were observed between humeral breadth and corrected arm girth (r = 0.41, p = 0.002), femur breadth and corrected thigh girth (r = 0.66, p < 0.001), and bimalleolar breadth and corrected calf girth (r = 0.72, p < 0.001). Conclusions: These findings suggest that Kenyan long-distance runners exhibit a lighter and more linear anthropometric profile than their European counterparts, whereas European runners display greater skeletal robustness and musculoskeletal development. Furthermore, local muscularity may be partly associated with underlying skeletal robustness. Full article

Background/Objectives: Hitting the wall (HTW) is a common and performance-limiting phenomenon in marathon running, traditionally attributed to glycogen depletion and reduced carbohydrate availability. However, the persistence of late-race performance collapse despite advances in fueling strategies suggests that HTW may not be explained by a single metabolic mechanism. Instead, HTW may represent a psychophysiological performance-collapse phenomenon arising from the interaction between physiological strain, perceived exertion, pacing regulation, and the athlete’s capacity to preserve function under prolonged stress. Methods: This narrative review aimed to synthesize the physiological and psychophysiological mechanisms contributing to HTW and to propose an integrative durability-based framework for understanding late-race performance deterioration during marathon running. Results: Current evidence indicates that HTW may emerge from the cumulative interaction of metabolic stress, thermoregulatory strain, dehydration, gastrointestinal dysfunction, neuromuscular fatigue, biomechanical deterioration, perceptual responses, and pacing errors. These stressors may progressively increase perceived effort, impair pace regulation, and reduce the athlete’s capacity to preserve physiological function and sustain the intended race pace. Within this framework, durability represents the ability to resist deterioration in physiological characteristics and performance capacity during prolonged exercise and may help explain why runners with similar fitness levels experience different late-race outcomes. Conclusions: HTW should therefore not be viewed simply as running out of fuel. Rather, it may represent the manifestation of reduced durability and psychophysiological dysregulation arising from multiple interacting stressors during marathon running. Strategies aimed at improving durability through marathon-specific training, optimized fueling, gastrointestinal tolerance, thermoregulatory preparation, neuromuscular resilience, pacing regulation, perceptual awareness, and individualized monitoring may reduce susceptibility to HTW.

The aim of this article is to provide a literature review of current approaches and recommendations for medical rehabilitation in stroke patients, with the goal of achieving the best possible outcomes for their condition and improving their quality of life. Materials and Methods: A narrative review was conducted of articles published in the databases available to us (PubMed, ScienceDirect, Google Scholar, PEDro, ResearchGate) that contain information regarding therapeutic management of stroke and, in particular, interventions aimed at motor recovery and improving quality of life. Included in this literature review were: scientific articles, guidelines on stroke and motor rehabilitation, clinical studies, longitudinal clinical studies, controlled clinical studies, systematic reviews, and meta-analyses published before April 2026, covering a ten-year period. Results: Data showing a trend toward higher patient survival rates following acute stroke were identified. For this reason, existing non-pharmacological approaches to motor recovery should be optimized. The rehabilitation process must begin as early as possible. Motor recovery depends on the establishment of motor control and the neuroplastic processes occurring in brain tissue. Rehabilitation is conducted by a rehabilitation team with the patient’s active participation, while monitoring motor rehabilitation potential. Conclusions: Rehabilitation is an essential component of post-stroke treatment. When timely and adequate medical rehabilitation is provided to stroke patients, there is a significant improvement in their overall condition and motor functions, as well as in their independence, self-care, and quality of life.
