Background: Osteoarthritis (OA) is a common degenerative joint disease that often leads to impaired postural control, pain, and reduced physical function. Exercise is considered a first-line treatment, with sensorimotor training being an effective approach for managing OA. However, the optimal method of sensorimotor training for individuals with OA has not yet been established. Thus, the aim of this study was to compare the effects of a 24-week Gyrokinesis method (GK) versus Pilates (PL) intervention on balance control, function, pain and kinesiophobia in women with knee OA. Methods: Twenty women (aged 60 ± 7 years) with grade 2 or 3 knee OA were assigned to either GK (n = 12) or PL (n = 8). Both groups trained twice weekly for 24 weeks. Pre- and post-intervention assessments included postural sway parameters (RMS, velocity, frequency), physical function tests (e.g., TUG, Sit-to-Stand), flexibility, pain (Brief Pain Inventory), kinesiophobia (Tampa Scale), and quality of life (SF-36). Results: GK resulted in significantly greater improvements than PL in postural sway mean velocity AP right (GK −53.85% vs. PL −20.17%), AP left (GK −43.48% vs. PL +13.45%), and ML left (GK −40.18% vs. PL +37.95), pain reduction (GK −82.5% vs. PL −33.3%), and physical function (Sit-to-Stand: GK +75.9% vs. PL +3.7%; TUG: GK −16.4% vs. PL −13.8%; Step Test right: GK +34.2% vs. PL +19.9%; Step Test left: GK +41.4% vs. PL +18.1%) (all, p < 0.05). No significant between-group differences were observed for kinesiophobia or SF-36 scores (both, p > 0.05). Conclusions: Gyrokinesis method may be more effective than Pilates in enhancing balance, reducing pain, and improving physical function in women with knee OA. These findings support the use of the Gyrokinesis method in rehabilitation programs for individuals with OA. Full article

Background and Objectives: The aim of this study is to objectively evaluate the effects of a six-week intermittent hypoxic–hyperoxic exposure program on blood pressure, respiratory function, cardiac autonomic nervous activity and C Reactive Protein levels in older adults. Materials and Methods: A double-blinded randomized controlled clinical trial was conducted on twenty-two older adults. Heart rate variability, respiratory function, blood pressure, C Reactive Protein levels and oxygen saturation were measured at two time points: baseline and after 6 weeks of treatment. Results: The maximal inspiratory pressure variable increased significantly in the EG (+7.50 ± 1.72 cmH2O, p < 0.01, ES = 1.17), while no changes were observed in the CG. The LF/HF variable decreased significantly in the EG (−1.23 ± 0.34 n.u, p < 0.01, ES = 1.11), with no significant changes in the CG. The C Reactive Protein variable decreased significantly in the EG (−7.00 ± 3.07 mg/L, p < 0.01, ES = 1.4), with no significant changes in the CG. Conclusions: Six weeks of intermittent hypoxic–hyperoxic exposure was associated with trends toward improvements in blood pressure, respiratory function, cardiac autonomic nervous activity, and C Reactive Protein levels, compared with a placebo application of the same therapy.

The global rise in nursing home (NH) populations presents substantial challenges, as residents frequently experience physical and cognitive decline, low physical activity, and high fall risk. This study evaluates the effectiveness of the BeSt Age App, a tablet-based, staff-supported mHealth intervention designed to promote physical activity and prevent falls among NH residents. Primary outcomes were fall incidence and fall risk (assessed using Berg Balance Scale [BBS] and Timed Up and Go [TUG]); fear of falling was a secondary outcome. In a cluster-randomized controlled trial across 19 German NHs, 229 residents (mean age = 85.4 ± 7.4 years; 74.7% female) were assigned to an intervention group (IG) or control group (CG). The 12-week intervention comprised twice-weekly, tablet-guided exercise sessions implemented by NH staff. Mixed models and generalized estimating equations were used under an intention-to-treat framework. The IG showed significantly greater improvement in BBS scores than the CG (group × time: F(1, 190.81) = 8.25, p = 0.005, d = 0.22), while group × time changes in TUG performance, fear of falling, and fall incidence were nonsignificant. These findings demonstrate the feasibility of a staff-mediated mHealth approach to fall prevention in NH residents, showing significant improvements in BBS scores as one functional indicator of fall risk, while TUG, fall incidence and fear of falling showed no change.

Understanding the long-term effectiveness of warm-up strategies is essential for enhancing neuromuscular performance in youth soccer players. This study examined the long-term effects of integrating squat exercises into the final phase of the warm-up over nine weeks on sprint, jump, change-of-direction (COD), and aerobic performance in youth soccer players. Twenty-four male U17 players were randomly assigned to either a squat-based warm-up (experimental group [EG]) or a rondo-based warm-up (control group [CG]). The EG trained twice weekly using 3–4 sets of 4–12 repetitions at progressively increasing intensities (50–85% of 1-RM). Performance was assessed pre- and post-intervention using 10 and 30 m sprint, squat jump (SJ), countermovement (CMJ), standing long jump (SLJ), 5-jump (5JT), T-half (COD), and VAMEVAL tests. The EG showed small to large significant gains in sprint (10 m: −2.21%, Cohen’s d [d] = 1; 30 m: −1.6%, d = 0.58), jumping (SJ: +9.29%, d = 1.23; CMJ: +12.08%, d = 1.83; SLJ: +7.14%, d = 0.8; 5JT: +2.33%, d = 0.32), and COD (−1.41%, d = 0.32), while aerobic endurance showed no significant change (p > 0.05). The CG showed no significant improvements (p > 0.05). Overall, integrating brief, progressive squat exercises at the end of warm-ups twice weekly led to chronic improvements in explosive neuromuscular performance, with minimal impact on aerobic endurance.

This study examined the longitudinal patterns of concurrent aerobic and resistance training in young elite rowers to address the limited understanding of how training volume, modality, and periodisation interact across a season, and to introduce a novel rowing-specific resistance training classification. A retrospective design was used to analyse group training data over 36 weeks (n = 9; 20.6 ± 0.5 years), and individual case studies over 55 weeks (n = 4; 21.6 ± 0.4 years). Aerobic loads, resistance training tonnage, and ergometer performance (power output) were tracked, with resistance exercises categorised as rowing-specific, upper accessory, lower accessory, or core. Weekly aerobic volume averaged 14.0 ± 5.0 h, and rowing-specific resistance accounted for 48–57% of total tonnage (14.13 × 10³ ± 7.41 × 10³ kg). Exploratory analyses suggested an inverse relationship between aerobic, and resistance loads across training phases and trends toward improved ergometer power in three of four case athletes. High concurrent loads also appeared to coincide with occasional missed or modified sessions in several cases. These findings highlight the importance of managing concurrent loads to support consistent training while offering a practical resistance training classification that may enhance monitoring and decision-making for developing rowers.

Background: Several studies have investigated the importance of physical exercise (PE) in overweight and obese populations; however, to date, no bibliometric study has analyzed research trends in high-intensity interval training (HIIT) in overweight and obese populations across the entire life course. Objective: To analyze the scientific output of HIIT trends in overweight and obese populations. Method: Theoretical study using bibliometrics as a research technique. A total of 282 studies were identified in the Web of Science and PubMed databases for analysis with VOSViewer software 1.6.20. The equation used was (“High-intensity interval training” OR HIIT) AND (overweight OR obesity OR “risk factors” OR “obesity risk”). Results: The year 2022 was the most productive year (n = 46). Most of the documents are research articles (81%), followed by review articles (15%). Most studies do not specify the characteristics of the sample, only mentioning the application of a HIIT program in overweight or obese individuals in (65.6%) of the total articles found. There is low scientific output in research focused on women (23.4%). The most frequently occurring words were “exercise” (n = 145), “obesity” (n = 131), “high-intensity interval training” (n = 81), “overweight” (n = 78), “physical activity” (n = 73), “body composition” (n = 46), “weight loss” (n = 45), “health” (n = 42), and “cardiorespiratory fitness” (n = 40). Conclusions: Scientific research has advanced the understanding of the impact of HIIT in relation to excess weight, with total fat reduction being one of the most frequently reported variables and no differences observed between sexes. HIIT has shown benefits in populations with overweight and obesity when compared with low-intensity training programs. Full article

Kabaddi is a contact sport that demands high physical fitness and specific technical skills. Although multiple training programs have been designed to improve performance, no systematic review had previously synthesized their effects on physical, physiological, and performance-related outcomes. This systematic review of randomized controlled trials aimed to evaluate the impact of different training interventions on physical fitness, physiological parameters, and sport performance in kabaddi players. A systematic review was performed in the Web of Science, PubMed, and Scopus databases up to May 2025. Randomized controlled trials analyzing training interventions in kabaddi players were included. Ten studies with a total of 458 participants were included. Interventions lasted between 6 and 12 weeks and comprised modalities such as strength training, plyometrics, combined training, circuit training, SAQ (speed, agility, and quickness), and Tabata. Nine studies reported significant within-group improvements in variables such as strength, speed, agility, and flexibility. In studies with between-group comparisons, training interventions could be more effective than control conditions. One study also reported improvements in physiological and hematological parameters. Overall, training interventions in kabaddi players may improve physical fitness, sport-specific performance, and certain physiological and hematological parameters. However, the evidence should be interpreted with caution given the predominantly fair methodological quality of the included trials. PROSPERO (CRD420251272758). Full article

In modern sports, straight-line sprinting alone is insufficient for assessing overall sprint performance, as athletes must also decelerate and change direction efficiently. Existing methods lack a single metric that integrates all abilities, enabling holistic assessment. This study aimed to develop a comprehensive and novel measurement of multidirectional sprinting ability. Fifty-four university athletes (21.0 ± 1.5 years; 69.6 ± 9.1 kg; 172.6 ± 7.8 cm) performed linear sprints, decelerations, and 45°, 90°, and 135° change of direction (COD) tests in both directions over 30 m. Sprint accelerations and decelerations were recorded using a Stalker ATS II radar gun, while COD times were measured with stationary time gates. Sprint velocities were used to generate a multidirectional sprint area (MDSA), which was divided into forward, backward, left, and right sections. The MDSA method is calculated as the area of the octagonal polygon created by plotting eight velocity vectors from different angles of sprints. Paired t-tests compared area differences across directions, and ANOVA tests were used to compare sporting codes and sex. The resulting model reported differences across sporting codes (p < 0.001), sex (p < 0.001), the total area value (p < 0.001), and total area percentage (p < 0.001). The results showed a significant difference between forward and backward accelerations (p < 0.001), but no significant difference between left and right movements (p = 0.244). The MDSA method offers a reliable, quantitative intra-session approach for assessing athletes’ multidirectional sprint abilities by calculating the octagonal area on the basis of velocity data. This holistic analysis identifies asymmetries and performance weaknesses, providing valuable insights for coaches. Full article

Studies have rarely examined the effects of changes in legal anti-doping knowledge (LADK) on doping tendencies in athletes. This study aimed to evaluate the effectiveness of a structured educational intervention focused on LADK and to analyze how LADK changes affect elite athletes’ doping tendency. The participants were athletes (n = 310; 156 females; 24.1 ± 4.2 years of age), all actively competing at the senior national or international level in either individual (N = 119) or team sports (N = 191), tested on sociodemographic-, sport-, doping-factors (including doping tendency—DT), and LADK. Participants were randomly divided into an experimental group (E: N = 140) and a control group (C: N = 170). The E group participated in a structured educational program on LADK. A pre- and posttest design was used to evaluate changes in LADK (dependent variable). Logistic regression was calculated to evaluate the association between LADK and binarized DT (negative vs. neutral/positive DT). Factorial ANOVA for repeated measurements revealed significant improvement in LADK in the E group, with significant ANOVA effects for time (F test = 35.8, p < 0.05) and time × group interaction (F test = 12.27, p < 0.05). The logistic regression did not reveal significant correlations between LADK and DT. Further studies exploring younger athletes, as well as long-term, multidimensional interventions, are warranted.

Volleyball physical performance relies on the interaction between mechanical power, metabolic efficiency, and ventilatory regulation during repeated high-intensity actions. This study examined mechanical and cardiopulmonary responses during three consecutive 15 s countermovement jump bouts in female volleyball players, using simultaneous cardiopulmonary exercise testing. Eighteen female athletes (18–28 years) completed the protocol with 60 s active recovery between efforts. Mechanical performance showed a progressive decline (p < 0.01), with jump height decreasing from 20.59 ± 3.04 cm to 19.30 ± 3.23 cm and power output from 15.80 ± 2.61 to 14.83 ± 2.25 W/kg (p = 0.001). Oxygen uptake (VO₂) increased from 16.40 ± 6.73 to 20.87 ± 6.08 mL/min/kg (p = 0.002), while respiratory exchange ratio (RER) rose above 1.0, suggesting a growing anaerobic contribution. VE/VO₂ and PetO₂ also increased significantly (p < 0.001), indicating ventilatory adjustment to metabolic stress. Despite these adaptations, recovery between efforts appeared incomplete, reflected by persistent ventilatory and metabolic activation. These findings suggest moderate oxidative efficiency and partial fatigue compensation under short recovery conditions. The testing model may serve as a practical approach to evaluate the interplay between mechanical and metabolic performance and to refine individualized conditioning strategies in volleyball players.

Youth soccer requires an integrated approach combining technical–tactical, physical, and psychological components to enhance performance and long-term engagement. Although Repeated Linear Sprint Training (LRST) and Repeated Change of Direction Speed (RCOD) training are widely used to improve fitness, direct comparisons of their effects on physical performance and perceptual responses in adolescent players remain limited. This study compared the effects of an 8-week LRST versus RCOD training program on physical performance, perceived exertion, and enjoyment in youth soccer players. Twenty-six male players were randomly assigned to an LRST group (n = 13) or an RCOD group (n = 13). Both groups completed two weekly sessions of their assigned training in addition to regular soccer practice. Pre- and post-intervention assessments included acceleration and sprint speed, change-of-direction (COD) performance (T-Half Test [THT], Illinois Agility Test [IAT]), lower-limb power (Five-Jump Test [5JT], Squat Jump [SJ], Countermovement Jump [CMJ]), and endurance-intensive fitness. Enjoyment and session-RPE were recorded after each training session. Both groups improved across all physical measures (main effect of time, p < 0.0001). Significant time × group interactions favored RCOD for THT (~1.6%), IAT (~1.1%), 5JT (~2.3%), CMJ (~5.2%), and SJ (~6.3%), with no overall main effect of group. Enjoyment was consistently higher in the RCOD group (p < 0.0001), while session-RPE did not differ between groups. In youth soccer, both LRST and RCOD effectively enhance physical performance. However, RCOD appears more effective for improving pre-planned COD and explosive performance while eliciting greater enjoyment without increasing perceived exertion. Incorporating structured RCOD training alongside linear sprint work may represent a practical strategy to optimize physical development and sustain player engagement. Full article

Aim: To investigate the effect of a 6-week sport-specific BET intervention on cognitive and physical performance in elite orienteering athletes. Methods: A single-arm cross-over study with an initial 6-week control period (CON) followed by a 6-week brain endurance training (BET). Thirteen Danish national team orienteering athletes participated in the study. CON athletes adhered to planned physical, cognitive, and technical training. BET athletes added 20 min of route choice assessment (RCA) training after each weekly aerobic training session. The 30 min Stroop color-word task and a sport-specific RCA task evaluated general and sport-specific cognitive performance. A submaximal (1000 m) and a maximal (5000 m) running test were also conducted. Endpoints were assessed pre and post CON and post BET. Results: Average time used per RCA task was 1.4 ± 0.4 s lower following BET (27%) (p = 0.009) compared with no change after CON. Similarly, the total number of correct Stroop answers increased by 13.8 ± 5.21 points (2%) after BET with no change after CON. RCA time use declined steeply from session 1–7, whereafter average time use plateaued. Running performance did not differ significantly between periods. Conclusion: BET improved sport-specific performance and aspects of general cognitive performance, and may effectively improve cognitive parts important for elite orienteering performance.

Background: Physical inactivity during adolescence remains a major public health concern, yet its multifactorial determinants are not fully understood in low- and middle-income settings. Objective: To identify and quantify the determinants of physical activity (PA) among Brazilian adolescents using a hierarchical logistic regression model that reflects the theoretical ordering of distal to proximal factors. Methods: A cross-sectional study was conducted with 856 adolescents (13–19 years). Data were obtained from the validated Brazilian Youth Risk Behavior Survey and the Brazilian Economic Classification Criteria (ABEP) socioeconomic questionnaire. PA was dichotomized according to World Health Organization recommendations. Hierarchical logistic regression examined five theoretical blocks: sociodemographic, anthropometric, substance use, weight/diet, and sedentary behavior. Results: Overall, 5 out of 17 predictors were significant in the full model. extended Body mass index (eBMI) was negatively associated with physical activity (OR = 0.331, 95% CI: 0.169–0.647, p = 0.001), while body mass was positively associated (OR = 2.078, 95% CI: 1.045–4.135, p = 0.037). Working status (OR = 1.235, 95% CI: 1.035–1.475, p = 0.019) and weight loss attempts (OR = 1.327, 95% CI: 1.042–1.690, p = 0.022) increased the odds of being active, whereas current smoking reduced it (OR = 0.715, 95% CI: 0.517–0.990, p = 0.043). Model discrimination improved progressively (AUC = 0.577 to 0.692). Conclusions: Physical activity among Brazilian adolescents was primarily influenced by behavioral and perceptual rather than demographic factors. These findings highlight the need for integrated interventions promoting muscle development, body positivity, and smoking prevention. Full article

Aerobic exercise with eicosapentaenoic acid (EPA) may enhance cognition via cerebrovascular pathways. We tested whether mild hyperbaric oxygen (HBO; 1.41 atmospheres absolute [ATA], approximately 30% O₂) adds to gains in cognitive processing capacity (throughput) versus normobaric normoxia (1.0 ATA, approximately 21% [20.9%] O₂). Healthy young adults (n = 16) performed cycling exercise at 60–70% VO_2peak for 60 min, twice weekly, for 4 weeks per environment with a 1-week washout; EPA (2170 mg·day⁻¹) was taken during each 4-week training phase (total 8 weeks) and was paused during the washout. An EPA-only control (n = 8) was included for supplementary analysis. The primary outcome was throughput (correct·min⁻¹; T1–T4); secondary outcomes were interference indices (I1: stroop interference, I2: reverse-stroop interference). Effects were estimated using linear mixed models [environment, time, environment × time; AR(1), REML] and Hedges’ g_av; accuracy used generalized estimating equations. Throughput improved mainly with time (T1–T2 p < 0.001; T4 p = 0.017; T3 p = 0.055), with no environment or interaction effects. I1/I2 showed no significant change, and one task exhibited an accuracy ceiling. Under safe, feasible conditions (≤1.41 ATA), aerobic exercise improved processing capacity (throughput) independently of environmental oxygenation level. The absence of detectable additive effects should be interpreted cautiously under conservative settings. Full article

Background: This study aimed to provide reference values for estimating training intensities in long-distance runners based on progressive incremental tests, considering differences related to sex and performance level. Methods: A total of 1411 endurance-trained runners (819 men and 592 women) completed a standardized treadmill protocol with gas exchange analysis to determine ventilatory thresholds and peak oxygen consumption (VO_2peak). Heart rate (HR) and running speed at each threshold were expressed relative to their peak values. Results: HR at second ventilatory threshold (VT2) occurred at 93.5 ± 2.5% of HR peak, and HR at first ventilatory threshold at 85.1 ± 4.6%. The relative running speeds at VT2 and VT1 corresponded to 87.6 ± 3.9% and 73.9 ± 5.5% of the speed at VO_2peak, respectively. In men, beginners exhibited higher relative HR and VO₂ values at the ventilatory thresholds than elite runners. In contrast, women displayed higher and more stable relative values across performance levels. Conclusions: These findings establish precise, evidence-based reference ranges derived from a large cohort of runners and highlight the need to consider sex and performance level when estimating exercise intensities. Individualized physiological assessment remains essential for accurate training prescription and performance optimization. Full article

The purpose was to characterize and compare biomechanical and coordinative parameters at maximum velocity between swimmers with Down syndrome and intellectual disabilities and examine these in relation to their anthropometrics. Nine swimmers (four with Down syndrome and five with intellectual disabilities) performed three bouts of 25 m crawl stroke, each at maximum velocity, which were recorded with the Qualysis motion analysis system. Anthropometric variables, BMI, and percentage of body fat were also assessed. Swimmers with Down syndrome presented a smaller height, acromion height, sitting height, arm span, hand length, hand width, foot length, foot width, and velocity than swimmers with intellectual disabilities. Swimmers with Down syndrome have disadvantageous anthropometrics and slower swimming velocities compared to swimmers with intellectual disabilities. Those swimmers also appear to present distinctive coordination (catch-up for Down syndrome and superposition for intellectual disabilities) and intracyclic velocity variation (Down syndrome presented higher values) compared to swimmers with intellectual disabilities, suggesting a lower swimming efficiency.

Background: Evidence on how physical and technical factors distinguish U-18 basketball levels is limited, yet these determinants may aid talent identification and development. This study examined differences in anthropometric, physical performance, and technical characteristics between high-level (HL; n = 38) and low-level (LL; n = 35) U-18 male basketball players and explored relationships between technical skills and key physical attributes across all participants. Methods: Participants were evaluated across anthropometry, physical performance, and basketball-specific technical skills. Statistical analyses assessed between-group differences and correlations, with significance set at p ≤ 0.05. Results: Compared to LL players, HL players exhibited significantly superior physical attributes, including greater height (Cohen’s d = 0.67) and arm-span (d = 0.65), reduced body fat (d = −0.58), and advanced performance metrics (10 m-speed running (d = −0.78), 20 m-speed running (d = −0.93), flexibility (d = 1.26), counter-movement jump height (d = 1.27), intermittent endurance (d = 1.18)). Technical proficiency in tasks such as 10 m- and 20 m-speed dribbling, maneuver dribbling and defensive sliding was also significantly faster in the HL group (d = −0.96, d = −1.05, d = −1.87, and d = −1.14, respectively). Several anthropometric and performance variables were strongly correlated with technical skills, indicating their relevance for distinguishing competitive levels. Conclusions: These findings underscore the interplay of physical, technical, and performance factors in high-level youth basketball. Coaches may use this information to guide targeted training strategies that support talent identification, player development, and competitive success. Full article

This study examined the effects of contrast water therapy (CWT) on physiological, perceptual, and performance-related recovery in collegiate male swimmers following high-intensity interval training. Fifteen freestyle swimmers (19.3 ± 1.1 years) completed two sessions of five 100 m maximal-effort intervals under two recovery conditions, CWT and passive rest (PAS), in a crossover design. The CWT protocol consisted of 10 alternating immersions in hot (40–41 °C, 60 s) and cold (20–21 °C, 30 s) water. Blood lactate (LA), blood pressure (BP), and subjective fatigue (VAS-FAS) were assessed at multiple time points. Compared with PAS, CWT resulted in significantly lower post-recovery blood LA (7.75 ± 2.08 vs. 10.86 ± 2.86 mmol/L, p = 0.002) and reduced subjective fatigue (6.60 ± 1.30 vs. 7.60 ± 0.91 cm, p = 0.021), whereas no significant differences were observed in BP or 100-m swimming performance. Individual-level analyses revealed heterogeneous responses, with most swimmers demonstrating improved lactate clearance and reduced fatigue following CWT, although performance responses varied among participants. These findings indicate that CWT facilitates physiological and perceptual recovery without producing immediate performance enhancement. CWT may be considered a practical short-term recovery option for competitive swimmers, although its effectiveness likely depends on individual response characteristics. Further research involving larger and more diverse samples is warranted to clarify optimal application parameters and individual recovery profiles. Full article

Background: People with multiple sclerosis (PwMS) face a wide range of social barriers, including stigma, limited support, and inaccessible environments, that restrict participation in physical activity (PA). Although PA is known to improve physical and psychological outcomes, its role in reducing social barriers has not been clearly synthesized. Methods: Following PRISMA 2020 guidelines, we conducted a systematic search of PubMed, Scopus, and Web of Science (January 1997–October 2025). Qualitative, quantitative, and mixed-methods studies examining how PA relates to social barriers, facilitators, or social outcomes for PwMS were included. Data were synthesized using a thematic analysis approach due to heterogeneity in study designs and outcomes. Risk of bias was assessed using JBI, NIH, RoB 2.0, and MMAT tools. Results: Twenty-nine studies met the inclusion criteria. The thematic synthesis identified three overarching mechanisms through which PA contributes to reducing social barriers: (1) peer support and shared experience, whereby group-based PA reduced isolation and normalized fluctuating symptoms; (2) guidance from knowledgeable professionals, which fostered trust, confidence, and perceived safety; and (3) changes in social identity, with participants shifting from a “sick role” toward identities such as “exerciser” or “athlete.” These mechanisms were supported by high-quality qualitative studies and by quantitative evidence showing small-to-moderate effect sizes for improvements in self-efficacy, social participation, and perceived social support. Conclusions: PA functions as a socially transformative practice for PwMS when delivered in group-based, supervised, and accessible formats. Programs designed to intentionally cultivate peer connection, professional support, and identity-building processes may be especially effective in overcoming social barriers and promoting social inclusion.

Background: Obesity alters metabolic, inflammatory, and immune responses, and acute exercise may affect these parameters differently according to body composition. This study investigated the acute effects of Spartacus exercise on metabolic, inflammatory, and immune markers in adolescent girls with overweight/obesity and normal weight. Methods: In this non-randomized clinical study, sixteen girls with overweight/obesity (BMI: 31.17 ± 3.85 kg/m²) and fourteen normal-weight girls (BMI: 21.93 ± 0.99 kg/m²) performed an intermittent running test (15 s effort, 15 s passive recovery), starting at 7 km·h⁻¹ with 1 km·h⁻¹ increments every 3 min until exhaustion. Blood samples were collected at rest (T0), immediately post-exercise (T1), and 30 min post-exercise (T2). CRP and ESR were assessed at baseline to characterize participants’ inflammatory status, while glucose and leukocyte subpopulations were evaluated to investigate acute exercise responses. Results: Fasting glucose, lipid profile (TC, TG, HDL-C, LDL-C), inflammatory markers (CRP, ESR), and leukocyte subpopulations were assessed. Significant group effects were observed for all metabolic and inflammatory markers, reflecting higher baseline values in participants with overweight/obesity compared with normal-weight participants (p < 0.05). Significant effects of time were found for glucose and leukocytes (p < 0.001), indicating acute exercise-induced changes, along with significant time × group interactions. Participants with overweight/obesity showed greater and more prolonged increases in glucose, total leukocytes, and neutrophils, whereas normal-weight girls returned to baseline within 30 min. Conclusions: Acute high-intensity intermittent exercise induces transient metabolic and immune responses in adolescents, with amplified and prolonged effects in those with obesity. These findings highlight the importance of considering body composition when prescribing exercise programs. Full article

Purpose: This single-athlete, longitudinal observational study describes training intensity distribution (TID) across two Olympic preparation cycles (Rio 2016 vs. Tokyo 2021) and explores whether differences in high-intensity exposure coincided with performance outcomes. Methods: An elite male 50 m freestyle specialist (personal best 21.27 s; height: 187 cm, weight: 80 kg, body mass index: 22.9 kg·m⁻², fat-free mass: 75.2 kg, and fat mass: 4.8 kg) was monitored across four mesocycle periods. TID is expressed as % of total swim volume in three zones: Z1 (low intensity), Z2 (threshold), Z3 [high intensity/race-pace, including High Intensity Interval Training (HIIT) and Sprint Interval Training (SIT)]. Both the coach and swimmer signed a written informed consent for the use of their data. Results: For Rio 2016, TID (Z1/Z2/Z3) was as follows: General 80/0/20, Specific 60/0/40, Pre-competition 40/30/30, and Taper 50/20/30, indicating a polarized approach. For Tokyo 2021, TID shifted to: General 85/0/15, Specific 60/0/40, Pre-competition 30/30/40, and Taper 40/20/40. Discussion: In this single athlete, a greater proportion of work in Z3 during the Tokyo cycle, particularly in the Pre-competition and Taper phases, probably coincided with improved performance (21.57 vs. 21.79 s). Conclusions: Although clear causal inference is not possible, these observations depict the probability that sprint-swim preparation for 50 m events needs a training volume oriented to Z3 and relatively less in Z1. However, the study’s design, the methods by which the TID was recorded, etc., limit any generalization about the interpretation of the findings. Therefore, future studies should address these limitations, providing more insights into improving the training on that kind of events. Full article

Background/Objectives: This cross-sectional study examined how training age, chronological age, and biological maturity influence motor and perceptual–cognitive performance in youth soccer players, with relevance for health and well-being through sport participation. Methods: Forty-one male athletes (age = 14.86 ± 0.81 years) completed a two-day field-based assessment following a holistic framework integrating motor (sprinting, jumping, and agility) and perceptual–cognitive components (psychomotor speed, visuospatial working memory, and spatial visualization). Biological maturity was estimated using the maturity offset method. Results: Regression analyses showed that biological maturity and training age significantly predicted motor performance, particularly sprinting, jumping, and pre-planned agility, whereas chronological age was not a predictor. In contrast, neither maturity nor training experience influenced perceptual–cognitive skills. Among cognitive measures, only psychomotor speed significantly predicted reactive agility, emphasizing the role of rapid information processing in dynamic, game-specific contexts. Conclusions: Youth soccer training should address both physical and cognitive development through complementary strategies. Physical preparation should be tailored to maturity status to ensure safe and progressive loading, while systematic training of psychomotor speed and decision-making should enhance reactive agility and game intelligence. Integrating maturity and perceptual–cognitive assessments may support individualized development, improved performance, and long-term well-being. Full article

Premenstrual syndrome (PMS) negatively affects women’s physical performance, emotional balance, and quality of life. Although pharmacological therapies exist, their side effects and limited effectiveness highlight the need for alternatives. This partially controlled, non-blinded, non-randomized prospective pilot study included 34 women aged 18–40 years and examined the effects of an eight-week structured yoga program. Participants met the same eligibility criteria and were comparable at baseline in age, sociodemographic characteristics, and PMS severity. The study group attended two weekly 90-min hatha yoga sessions and completed a 15-min daily home practice, while controls maintained their usual physical activity. Outcome measures included body composition, hip range of motion, spinal mobility (flexion and lateral flexion), and Premenstrual Symptoms Screening Tool (PSST) scores. After eight weeks, the yoga group showed significant reductions in body weight and fat mass and an increase in muscle mass. Hip external rotation improved significantly among yoga participants, while changes in spinal mobility did not reach statistical significance. The intervention group showed a significant reduction in PMS symptom severity, while the control group showed no significant change. The findings suggest that regular yoga practice can enhance physical functioning and alleviate PMS-related symptoms, supporting its role as a movement-based approach for improving women’s health.

Natural bodybuilders optimize their body composition by combining training and nutrition strategies. This study compared the resistance training practices of amateur and professional natural bodybuilders, during the pre-contest phase and in general. Fifty-six drug-tested Spanish bodybuilders (27 amateurs, 29 professionals) completed a 34-item survey assessing training and competing experience, training frequency, exercise selection, weekly sets per muscle group, repetition ranges, and contest-preparation characteristics. Participants trained ≈5 days·week⁻¹ (Amateur: 4.74 ± 0.45; Professional: 4.83 ± 0.47) and most muscle groups were trained >1 and <3 times·week⁻¹. Weekly direct sets per muscle group averaged ~8–17, with the highest volumes for back (Amateur: mean 15.3; Professional: mean 17.0 sets·week⁻¹) and chest (Amateur: 11.8; Professional: 12.7) and the lowest for hamstrings (Amateur: 8.56; Professional: 8.10). The dominant repetition range was 6–10 reps (Amateur: 74.1%; Professional: 89.7%), with 11–15 reps commonly selected as the secondary range. No statistically significant differences were detected between amateurs and professionals for the main training variables, although professionals showed a trend toward more years competing (p = 0.078, d = 0.49). In conclusion, high-level natural bodybuilders adhere to practices that are generally in line with current scientific recommendations. However, interindividual variability highlights the need for individualized programming. Full article

The gut microbiota represents a complex microbial ecosystem with the potential to influence athletic performance, energy metabolism, inflammatory responses, and recovery capacity in athletes. However, the specific relationship between microbiota and performance in combat sport athletes remains poorly characterized. This scoping review systematically maps current evidence on gut microbiota-combat sports performance relationships, identifies microbial response patterns to training and competition, evaluates nutritional prebiotic and probiotic interventions, and highlights methodological gaps to guide future research. Following the PRISMA-ScR framework, 8 studies were identified, which included 247 elite and high-level athletes, comprising 169 males and 78 females, with sample sizes ranging from 12 to 53 across wrestling, mixed martial arts, martial arts, judo, and taekwondo. Associations were observed between gut microbiota characteristics and training intensity, competition level, weight management, and pre-competition psychological states. Limited taxonomic consistency was observed across studies, with most bacterial genera appearing in a single investigation, precluding the identification of robust sport-specific microbial signatures. Preliminary trials demonstrated improvements in gastrointestinal symptoms, aerobic performance, and psychological fatigue with prebiotic and probiotic interventions. However, small sample sizes and methodological heterogeneity across studies limit generalizability and preclude definitive conclusions regarding the role of gut microbiome in combat sports performance.

Background: Periodontal disease is prevalent among elite athletes globally, yet its status in Japanese athletes remains unclear. This study assessed periodontal risk in Japanese university athletes and its association with oral health-related quality of life (QOL), sports performance, and immune status. Methods: A cross-sectional study was conducted with 313 university athletes (basketball, volleyball, athletics). Periodontal risk was evaluated using a Trypsin-Like Peptidase activity assay (TLP-AA) kit; a score ≥ 1.5 indicated the presence of Red Complex bacteria (positive risk). Participants completed the Oral Impacts on Daily Performance (OIDP), Oslo Sports Trauma Research Centre (OSTRC) overuse injury, and Immune Status Questionnaires (ISQ). Results: Positive periodontal risk was identified in 25.9% (81/313) of athletes. While overall prevalence was not statistically different from the general population (17.8%), specific associations emerged. Positive risk was significantly associated with “pain related to sports” (OSTRC) overall (p = 0.016) and specifically in males (p = 0.004). Among track and field athletes, positive risk was associated with difficulty “smiling/laughing” (OIDP, p = 0.033) and lower self-rated general health (p = 0.032) and immune functioning (p = 0.047). Conclusions: Periodontal risk is notable in Japanese university athletes and is significantly associated with sports-related pain and specific QOL domains. Regular oral health monitoring may be crucial for maintaining athletic performance and well-being. Full article

One of the most prominent topics in contemporary research is how individuals can adopt behaviors and attitudes that support successful aging (SA) throughout their life course. Participation in sport is widely regarded as an important behavioral strategy that contributes to physical, psychological, and social resources relevant to SA. This study examined the association between Tennis Involvement (TI) and orientations toward successful aging in a sample of 224 masters tennis players with a mean age of approximately 51 years. Data was collected using the Tennis Involvement Scale and the Successful Aging Scale, which was applied to assess strategies and predispositions related to successful aging rather than aging outcomes. A structural model was tested using descriptive statistics, reliability analysis, correlation analysis, Confirmatory Factor Analysis (CFA), and Structural Equation Modeling (SEM). The hypotheses assumed that all factors of tennis involvement would be positively correlated with SA, “tackling problems-TP”, and “healthy lifestyle-HL”. However, the SEM analysis results provided partial support for hypotheses H1a and H1c. Only the “social bonding” factor showed a significant and positive correlation. Remarkably, however, the “centrality” factor showed a negative trend, contrary to expectations, and statistically significant correlations were found. No significant correlations were identified between age, TI, and SA. However, there were positive and significant correlations between players’ weekly tennis playing time (both in days and hours) and SA, TP, and HL. In conclusion, the results indicate that, among middle-aged masters tennis players, tennis involvement is associated with both positive and negative aspects of successful aging, and longer tennis playing duration is associated with more favorable successful aging strategies.

This study aimed to examine the effects of eight weeks of repeated backward sprint training (RBST) versus repeated forward sprint training (RFST) on physical fitness measures. Twenty-three postpubertal male basketball players (mean age = 15 years) were randomly assigned to either an RBST group (n = 12) or an RFST group (n = 11). Pre- and post-intervention assessments measured 5-, 10-, and 20 m sprint performance, Y-agility, 505 change of direction (CoD) speed, countermovement jump (CMJ), standing long jump (SLJ), and RSA (RSA best time [RSA_best] and RSA mean time [RSA_mean]). The RBST group significantly improved in all measures (p < 0.05; 6.11 to 19.25%; Effect size [ES] = 0.32 to 1.05) except RSA_best. The RFST group significantly improved 10 m sprint, SLJ, RSA_best, and RSA_mean (p < 0.05; 6.25 to 17.84%; ES = 0.05 to 0.80). Between-group analysis revealed that RBST outperformed RFST in Y-agility and SLJ (p < 0.05; ES = −1.03 and 0.16, respectively). RBST was more effective for improving agility and lower-body power, while RFST provided a slight advantage in peak RSA. These findings suggest that incorporating task-specific sprint training may optimize physical performance in male youth basketball players. Full article

This study examined the trial-to-trial reliability and usefulness of the Output Sports inertial measurement unit (IMU) in measuring reactive strength index (RSI) derived from the Drop Jump (DJ) and 10-5 rebound jump test (10-5 RJT). Twenty-three male elite intercounty hurlers (mean ± SD; age: 24.3 ± 3.7 years, mass: 88.0 ± 6.3 kg, height: 183.8 ± 5.8 cm, experience at elite level: 5.8 ± 3.8 years) performed three trials each of the DJ and 10-5 RJT, on familiarisation and testing days. There was one week between familiarisation and testing. Reliability was determined by intraclass correlation (ICC) and coefficient of variation (CV) analyses. Usefulness was assessed by comparing typical error (TE) with the smallest worthwhile change (SWC). Both the DJ and 10-5 RJT were reliable in determining RSI, with CV ≤ 10% and ICC ≥ 0.8. The TE was 0.09 and 0.08 for the DJ and 10-5 RJT, respectively. Both tests were unable to detect the SWC, rating them as ‘marginal’; however, they were rated as ‘good’ in detecting moderate change in RSI. The Output Sports IMU is reliable in determining RSI for the DJ and 10-5 RJT; however, it is unable to detect the SWC. Future research must determine validity of the Output Sports IMU in measuring RSI. Full article

Tai Chi has evolved into a widely used mind–body practice increasingly incorporated into complementary therapy, rehabilitation, and public health. This study provides an updated global bibliometric overview, with VOSviewer mapping publication performance, co-authorship networks, and keyword-based thematic clusters. Articles and reviews with Tai Chi–related terms in the title were retrieved from Scopus, with no restrictions on language or publication year. A total of 2253 publications from 1978 to 2025 were analyzed, revealing steady growth, concentrated largely in the past decade. China led the publication output, while the United States had the highest number of citations, forming a dual-core pattern. The field is largely driven by a small group of authors and regional clusters, and its visibility in mainstream medical journals remains limited. Nine software-generated keyword clusters were manually synthesized into five themes: motor function (balance and fall prevention), musculoskeletal conditions (osteoarthritis, rheumatoid arthritis, fibromyalgia), chronic disease management (cardiovascular disease, stroke, COPD), psychological health (quality of life, depression, anxiety, mindfulness), and cognitive aging (dementia, mild cognitive impairment). Future progress requires greater methodological rigor, including mechanistic inquiry, long-term study designs, and community- or population-level applications, along with stronger international collaboration and deeper integration into clinical and public health practice.
