Background:Social media plays an important role in shaping body image and self-perception,particularly among appearance-sensitive groups such as athletes.Although problematic social media use has been linked to body image outcomes through processes such as social comparison,self-presentation,and evaluation sensitivity,these mechanisms remain underexplored among athletes with physical disabilities.This study aimed to examine the associations between social media use,addictive use patterns,and body image perception in this population,with a focus on these underlying psychological mechanisms.Methods:A total of 165 athletes with physical disability participated in this quantitative cross-sectional study.Data were collected through online surveys,including demographic questions,the Athlete Social Media Use Scale(content creation,usage frequency,and social media addiction subdimensions),and the Body Image Scale(negative perception,evaluation sensitivity,positive perception,and body modification).Parametric tests,correlation analyses,and group comparisons were performed to assess relationships between social media behaviors and body image dimensions.Results:Problematic social media use was moderately associated with higher negative body image and lower positive body image among athletes with physical disabilities(r=0.32–0.41,all p<0.001).Regression analysis indicated that overall social media use was a significant predictor of body image perception after controlling for demographic variables(β≈0.45,p<0.001),explaining approximately 19.5%of the variance.Mediation analyses using bootstrapping revealed that these psychological mechanisms partially mediated the relationship between problematic social media use and body image perceptions,with small-to-moderate indirect effects,indicating both statistical and practical significance.Conclusion:The findings indicate that not only general social media use but also addictive and problematic usage patterns are linked to vulnerable aspects of body image among athletes with physical disabilities.Increased exposure to idealized digital representations and upward social comparison processes may heighten sensitivity to external evaluation and undermine positive body perception.These results highlight the need for digital literacy initiatives,psychoeducational interventions,and supportive online environments that promote healthier social media engagement and body image among disabled athletes. 展开更多

BACKGROUND Acute Achilles tendon rupture(AATR)is a debilitating injury that significantly impacts elite athletes,particularly those in the national football league(NFL).While return to play(RTP)and performance outcomes are critical to career longevity,these outcomes may be influenced by factors such as injury timing,player position,and unreported rehabilitation variation.Prior literature lacks a comprehensive synthesis of these outcomes in NFL athletes.AIM To systematically evaluate return-to-play rates,performance outcomes,and career longevity following AATR among NFL athletes,while considering the methodological quality of available evidence.METHODS A systematic review was conducted in May 2024 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed,EMBASE,and Cochrane Library databases.Studies reporting outcomes following AATR in NFL players were included.Data were extracted on demographics,timing of injury,RTP,games played,and performance metrics.Pooled rates and weighted means were calculated based on sample size.Risk of bias was assessed using the Risk of Bias in Non-Randomised Studies of Interventions tool.No meta-analysis or statistical heterogeneity testing(e.g.,I²)was performed due to the descriptive nature of the analysis.RESULTS Twelve studies including 676 NFL athletes met inclusion criteria.The weighted mean age at injury was 27.3±1.4 years,with a mean of 5.2±1.2 years in the NFL prior to injury.Linebackers(19.0%),wide receivers(11.9%),and running backs(9.0%)were most affected.AATRs occurred most often during the preseason(50.4%).The overall RTP rate was 66.2%,with a weighted mean time of 10.9±1.3 months.Post-injury,players averaged 12.9 games/season and played for 2.2±0.8 additional seasons.Performance significantly declined regardless of position.Most studies lacked data on rehabilitation protocols and exhibited moderate to critical risk of bias.CONCLUSION NFL athletes experience a relatively low return-to-play rate and substantial decline in performance following AATR.These outcomes are further influenced by high heterogeneity in study quality and the unreported variability in post-operative rehabilitation.These findings underscore the need for prospective,standardized research and may inform team physicians and athletic trainers in developing evidence-based RTP strategies. 展开更多

Background Exercise-induced bronchoconstriction(EIB)is a prevalent respiratory condition among summer sport elite athletes,yet epidemiological data from Asian populations remain scarce.The objective of this study was to investigate the prevalence,sport-specific patterns,and physiological characteristics of EIB in Chinese summer sport elite athletes.Methods A cross-sectional study of 500 summer sport elite athletes across 17 sports was conducted.Participants underwent standardized exercise challenge testing,spirometry,and serum biomarker assessments(eosinophils,interleukin-5(IL-5),interleukin-8(IL-8),Clara Cell protein 16(CC16),immunoglobulin E(IgE),and uric acid(UA)).Results EIB prevalence was 27.6%(138/500),with significant variation across sports:highest in swimming(51.52%)and lowest in wrestling(6.45%).Female athletes were more prevalent than males(31.1%vs.23.7%,p=0.030).Outdoor sports demonstrated higher rates than indoor disciplines(37.4%vs.19.4%,p=0.002).EIB-positive athletes showed pronounced post-exercise declines in forced expiratory volume in 1 s(FEV1)at 5 min(p<0.001)and elevated inflammatory biomarkers:eosinophils(p<0.001),neutrophils(p=0.019),IL-5(p<0.001),IL-8(p<0.001),CC16(p<0.001),IgE(p<0.001),and UA(p<0.001)vs.EIB-negative counterparts.Conclusion This is the first large-scale study of Chinese athletes to reveal EIB prevalence exceeding global averages.Distinct risk profiles emerge,associated with gender,athletic level,sport type,and environmental factors.The findings outline the need for targeted screening programs and biomarker-guided management to mitigate respiratory health risks in athletic populations. 展开更多

Background:A greater prevalence of arrhythmias has been described in endurance athletes,but it remains unclear whether this risk persists after detraining.We aimed to evaluate the prevalence of arrhythmias and their relationship with cardiac remodeling in lifelong and retired master endurance athletes compared to non-athletic controls.Methods:We performed a cross-sectional analysis of observational studies that used echocardiography and cardiac magnetic resonance to detail cardiac structure and function,and Holter monitors to identify atrial and ventricular arrhythmias in 185 endurance athletes and 81 non-athletic controls aged≥40 years.Athletes were categorized as active lifelong(n=144)or retired(n=41)based on hours per week of high-intensity endurance exercise within 5 years of enrollment and validated by percentage of predicted maximal oxygen consumption(VO2max).Athletes with overt cardiomyopathies,channelopathies,pre-excitation,and/or myocardial infarction were excluded.Results:Lifelong athletes(median age=55 years(interquartile range(IQR):46-62),79%male)were significantly fitter than retired athletes(median age=66 years(IQR:58-71),95%male)and controls(median age=53 years(IQR:48-60),96%male),respectively(predicted VO2max:131%±18%vs.99%±14%vs.98%±15%,p<0.001).Compared to controls,athletes in our cohort had a higher prevalence of atrial fibrillation((AF):32%vs.0%,p<0.001)and non-sustained ventricular tachycardia((NSVT):9%vs.1%,p=0.007).There was no difference in prevalence of any arrhythmia between lifelong and retired athletes.Lifelong athletes had larger ventricular volumes than retired athletes,who had ventricular volumes similar to controls(left ventricular end-diastolic volume indexed to body surface area(LVEDVi):101±20 m L/m2vs.86±16 mL/m2vs.94±18 mL/m2,p<0.001;right ventricular end-diastolic volume indexed to body surface area(RVEDVi):117±23 mL/m2vs.101±19 mL/m2vs.100±19 mL/m2,p<0.001).Athletes had more scar(40%vs.18%,p=0.002)and larger left atria(median volume=45m L/m2(IQR:38-52)vs.31 mL/m2(IQR:25-38),p<0.001)than controls,with no difference in atrial volumes and non-ischaemic scar between the athlete groups.Conclusion:Master endurance athletes have a higher prevalence of AF and NSVT than non-athletic controls.Whereas ventricular remodeling tends to reverse with detraining,the propensity to arrhythmias persists regardless of whether they are actively exercising or retired. 展开更多

This study aimed to investigate the energy supply of athletes,who had a mild form of coronavirus infection(COVID-19)under cycling ergometric load(CEL)to substantiate the timing of recovery,as well as to determine the volume and intensity of physical activity.Eighty-seven athletes aged from 18 to 28 years old,involved in cyclic sports,were examined.Group I consisted of 52 athletes with COVID-19,and group Ⅱ consisted of 37 healthy self-isolating athletes.In addition to the comprehensive examination,the tested athletes underwent special examinations:the study of diagnostic material using methods of nucleic acid amplification,spirography and spiroergometry,electrocardiography(ECG),and CEL.The results of athletes from both groups did not differ significantly(p>0.5)in the 1st,2nd,and 3rd examinations.The second examination revealed a discrepancy between functional reserves and the load performed,as evidenced by the difference in the recovery rate of most indicators,the results of the third examination in the long-term period(6 months)showed that the athletes of the first group did not have any violations of the parameters of the respiratory function(RF)and cardiovascular system at rest,after performing CEL,as well as in the recovery period.The results suggest that the full resumption of training loads and participation in competitions are possible only with the complete normalization of the functional state of the cardiorespiratory system.The most informative indicators are:minute ventilation(V E),heart rate(HR),oxygen pulse(OP),and coefficient of oxygen utilization(COU). 展开更多

Background: Biological maturation refers to the progressive process through which individuals transition toward an adult state during growth and development. To address the challenges posed by differences in biological maturity and the limitations of existing testing methods, particularly in adolescent sports contexts, there is a pressing need for a non-invasive method that is convenient, accurate, and broadly applicable to monitor the biological maturity of adolescent athletes comprehensively. In response to this need, a maturity assessment method based on the smartphone application Maturo has been developed. This study evaluates the accuracy and validity of the Maturo software, an automated tool for estimating biological age and related maturation metrics.Methods: A sample of 103 actively training teenage athletes aged 9-17 years. The sample included 76 males(age = 11.74 ± 1.55 years, mean ±SD) and 27 females(age = 13.95 ± 1.40 years), all without medical conditions that might impact growth or development.Results: Compared to traditional expert evaluations, the intraclass correlation coefficients(ICCs) and Pearson correlation coefficients demonstrated reliable positive correlations and significant agreement between the Maturo software and expert methods across multiple metrics, such as biological age(ICC = 0.965, R = 0.97), corrected biological age(ICC = 0.973, R = 0.99), predicted adult height(ICC = 0.991, R = 0.99), and percentage of adult height achieved(ICC = 0.955, R = 0.97). The Bland-Altman plots provided additional evidence of the validity of the Maturo software estimations, showing low systematic error in most measures. The linear regression analysis produced excellent adjusted R2values: 0.95for biological age and 0.99 for anticipated adult height. The Maturo approach demonstrated a high level of dependability in classifying teenagers into groups based on their maturity status and timing. The κ coefficients of 0.93 for maturity status and 0.82 for maturity timing indicate a nearly perfect agreement with the expert technique.Conclusion: While the Maturo software's non-invasive nature, cost-effectiveness, and ease of use could make it a potential tool for regular monitoring of growth and maturation in young athletes, its promising results in assessing maturation should be interpreted with caution due to limitations such as sample size and demographic constraints. Further longitude research with larger and more diverse populations is needed to validate these preliminary findings and strengthen the evidence for its broader applicability. 展开更多

Background:Psychological stress from academic and athletic demands adversely affects college athletes’mental health,the underlying mechanisms of this relationship remain insufficiently understood.Therefore,this study focuses on the Chinese college athletes and explores the relationship among mindfulness,stress coping,burnout,and mental health.Methods:The study used a sample of 500 student athletes from five higher sports colleges in China,collected data on various variables using standardized psychometric instruments,and analyzed the path relationships and mediating effects among the variables using structural equation modeling(SEM)and bootstrap methods.Results:Mindfulness significantly improved stress coping ability(β=0.721,p<0.001),and stress coping significantly improved mental health(β=0.606,p=0.027)and reduced burnout levels(β=−0.225,p<0.001).Burnout had a significant negative impact on mental health(β=−0.113,p=0.015).Mediation effect analysis revealed that stress coping played a mediating role between mindfulness and mental health(β=0.797,p<0.001),while the mediating effect of burnout was not statistically significant.When stress coping and burnout were considered simultaneously,they mediated the relationship between mindfulness and mental health(β=0.033,95%CI:[0.004,0.104],p=0.026).Conclusions:Mindfulness indirectly affects the mental health of college athletes by enhancing stress coping ability.The findings highlight the importance of integrating mindfulness training and stress coping strategies in sports training.Future studies should consider differences among sports to clarify the relationships between mindfulness,stress coping,burnout,and mental health. 展开更多

BACKGROUND In pediatric and adolescent athletes,there is a lack of understanding about the impact of factors such as race on the structural or cardiovascular adaptations in response to exercise which may unnecessarily disqualify athletes from the competitive sport.We hypothesized that race has an impact on cardiac adaptions in non-adult athletes.AIM To explore the racial disparity in electrocardiographic(ECG)and echocardiographic(ECHO)parameters in healthy adolescent athletes.METHODS A comprehensive electronic systematic literature search using MEDLINE database was performed from inception to September 20,2024.Inclusion criteria included randomized or observational cohort studies that recruited adolescent competitive athletes in any sport discipline and compared between the Black and White races with an age range of 12-18 years.RESULTS Of 723 records that were identified by the literature search,seven studies(n=5036)were included.The mean age was 13.0-18.0 years old with male predominance.Black athletes had significantly longer PR interval[mean difference(MD)=17.49 millisecond,95% CI:11.70-23.29]and shorter QRS complex duration(MD=-7.35 millisecond,95% CI:-9.17 to-5.53)and corrected QT interval(MD=-4.95 millisecond,95% CI:-7.69 to-2.22)than the White athletes.Black athletes were approximately four times more likely to have first-degree atrioventricular(AV)block,inverted T wave,ST-segment elevation,and left atrium(LA)enlargement than their White counterparts.In terms of ECHO parameters,Black athletes had significantly greater septal wall thickness(MD=0.85 mm,95% CI:0.62-1.07),posterior wall thickness(MD=1.07 mm,95% CI:0.36-1.78),relative wall thickness(MD=0.03,95%CI:0.001-0.06),maximal wall thickness(MD=1.05 mm,95%CI:0.28-1.83),and LA diameter(MD=1.64 mm,95%CI:0.16-3.12).CONCLUSION Race has an impact on the ECG and ECHO parameters that reflect cardiac adaptations in adolescent athletes.Black athletes tend to have an increased prevalence of distinct ECG changes such as first-degree AV block and T-wave inversions compared with their White counterparts.Despite having thicker septal and posterior walls,the overall prevalence of left ventricular hypertrophy did not differ between the races. 展开更多

In order to help athletes optimize their performances in competitions while prevent overtraining and the risk of overuse injuries,it is important to develop science-based strategies for optimally designing training programs.The purpose of the present study is to develop a novel method by the combined use of optimal control theory and a training-performance model for designing optimal training programs,with the hope of helping athletes achieve the best performance exactly on the competition day while properly manage training load during the training course for preventing overtraining.The training-performance model used in the proposed optimal control framework is a conceptual extension of the Banister impulse-response model that describes the dynamics of performance,training load(served as the control variable),fitness(the overall positive effects on performance),and fatigue(the overall negative effects on performance).The objective functional of the proposed optimal control framework is to maximize the fitness and minimize the fatigue on the competition day with the goal of maximizing the performance on the competition day while minimizing the cumulative training load during the training course.The Forward-Backward Sweep Method is used to solve the proposed optimal control framework to obtain the optimal solutions of performance,training load,fitness,and fatigue.The simulation results show that the performance on the competition day is higher while the cumulative training load during the training course is lower with using optimal control theory than those without,successfully showing the feasibility and benefits of using the proposed optimal control framework to design optimal training programs for helping athletes achieve the best performance exactly on the competition day while properly manage training load during the training course for preventing overtraining.The present feasibility study lays the foundation of the combined use of optimal control theory and training-performance models to design personalized optimal training programs in real applications in athletic training and sports science for helping athletes achieve the best performances in competitions while prevent overtraining and the risk of overuse injuries. 展开更多

Background:Team-sport players have a particularly high injury risk.Although female sex is considered a risk factor,it is still unknown whether female and male team-sport players,in fact,differ in their injury rates.We aimed to compare injury rates between female and male players by systematically reviewing and meta-analyzing injury surveillance studies of both sexes in order to evaluate sex-specific differences in team-sport injuries.Methods:Studies that prospectively collected injury data for high-level female and male players(age≥16 years)in basketball,field hockey,football(soccer),handball,rugby(union and sevens),and volleyball were included.Two reviewers(AZ and ALR)independently assessed study quality and extracted data for overall,match,training,and severe injuries(>28 days’time loss)as well as data regarding injury locations and types.Incidence rate ratios(IRRs)were pooled in a meta-analysis,and meta-regression analysis was performed when 10 or more studies were available.Results:Of 20 studies,9 studies reported injury data from football,3 studies from rugby,3 studies from handball,1 study from basketball,1 study from field hockey,2 studies from volleyball,and 1 study from basketball and field hockey.For overall injuries,the pooled IRR=0.86(95%confidence interval(95%CI):0.76-0.98)indicated significantly more injuries in male than in female players.For injury location,the pooled IRR showed higher injury rates in male athletes than in female athletes for upper extremity,hip/groin,thigh,ande foot injuries.Female players had a significantly higher rate of anterior cruciate ligament injuries(IRR=2.15,95%CI:1.27-3.62)than male players.No significant sex-specific differences in IRR were found for match,training,severe injuries,concussions,or ankle sprains.Conclusion:Our meta-analysis provides evidence for sex-specific differences in the injury rates in team sports.Further epidemiological studies including both sexes in sports other than football are needed in order to strengthen the evidence. 展开更多

BACKGROUND Fixed esotropia in high myopia,characterized by irreversible inward ocular deviation and abduction limitation,presents unique therapeutic challenges for athletes requiring precise binocular coordination.The combination of Yokoyama surgery and medial rectus muscle recession has been proposed as an advanced technique addresses both myopia-induced globe displacement and muscular imbalance offering potential advantages over conventional strabismus surgery in this population.AIM To investigate the effects of the modified Yokoyama surgery coupled with medial rectus muscle recession in restoring ocular motility and correcting esotropia among athletes with high myopia and fixed esotropia.METHODS A retrospective study analyzed 30 highly myopia athletes(57 eyes)with fixed esotropia treated at our hospital from January 2022 to April 2024.The participants were allocated into two groups based on the surgical method:The traditional group(n=15,29 eyes)received conventional strabismus surgery,and the combined group(n=15,28 eyes)underwent modified Yokoyama surgery in combination with medial rectus muscle recession.Eye movement improvement,esotropia alleviation,and complications were compared preoperatively and at 1,3,and 6 months post-treatment.RESULTS Both surgical groups exhibited similar baseline scores(traditional:-4.04±0.38 vs combined:-4.12±0.45,P>0.05),showing severe preoperative limitations in ocular motility.Following the intervention,the combined group achieved significantly better outcomes at both 1 month(combined:-2.25±0.28 vs traditional:-2.67±0.32)and 3 months(combined:-1.48±0.28 vs traditional:-1.76±0.43),with statistically significant improvements(P0.05).Prior to treatment,all patients in both groups exhibited a compensatory head posture(CHP).Following treatment,the incidence of CHP decreased to 6.67%in the combined group and 20.00%in the traditional group,both reductions being significant compared to pretreatment levels(P0.05).The rates of improvement in esotropia showed an increasing trend in both groups at 1 month(46.43%vs 34.48%),3 months(78.57%vs 51.728%),and 6 months(100.00%vs 89.66%)post-treatment.Notably,the combined group had a significantly higher improvement rate than the traditional group at the 3-month follow-up(P0.05).The combined group experienced slightly lower but not significant(combined group:0.00%vs traditional:3.45%)as opposed to the traditional group(3.45%;P>0.05).CONCLUSION The combination of modified Yokoyama surgery and medial rectus muscle recession provides effective and safe approach to improving in eye movement and esotropia in athletes with high myopia and fixed esotropia,offering reliable clinical benefits. 展开更多

This study aimed to evaluate the magnesium status of athletes via a systematic review of cross-sectional studies. A comprehensive systematic search was conducted in PubMed, Web of Science, SPORTDiscus, Cochrane Library electronic databases, and other sources before April 5, 2021. Fourteen studies were included in the systematic review, involving 855 athletes and 521 control subjects. Serum magnesium concentration was significantly lower in athletes(mean difference(MD):-0.04 mmol/L;95% confidence interval(CI):-0.06 to-0.01;P = 0.02)in spite of significantly higher dietary magnesium intake(MD: 51.72 mg/day;95% CI: 14.62 to 88.83;P = 0.006). Meta-analysis showed that 24-h urinary magnesium excretion in athletes was significantly higher than that in the untrained population(MD: 0.76 mmol/day;95% CI: 0.11 to 1.41;P = 0.02). Despite higher total dietary magnesium intake, athletes generally have lower serum magnesium concentration and higher 24-h urinary magnesium excretion, demonstrating that the magnesium requirement of athletes is higher than the untrained population. It is necessary to carry out a dietary assessment and nutrition counseling to help athletes adopt proper diets to meet their nutritional needs in exercise. 展开更多

Purpose： The present study aimed to examine the effect of static stretching （SS） and a sport-specific dynamic stretching （DS） session at two specific post-stretch time intervals in highly trained female athletes （age 19.90 ± 1.60 years; height 1.80 ±0.06 m; mass 76.87 ± 9.95 kg） on kinetic parameters of peak force, time-to-takeoff, and rate of force development. Methods： The data were collected over 3 days （randomized within subject design with control session）. Following each stretch session （SS vs. DS vs. control） of equal duration （7 min total： 30 s per targeted muscle group） participants performed countermovement jumping on a force platform at 1 and 15 rain after stretching. Results： The DS session significantly improved upon kinetic variables of rate of force development, peak force, and time-to-takeoffrelative to SS at 1 min after stretching. No significant effect was found at 15 min. Conclusion： Together these findings suggest that when training and competing to jump quickly and maximally the female athlete should incorporate DS instead of SS as part of their pre-competition warm-up, but conduct performance within 15 min of their warm-up to elicit maximal gains 展开更多

Triangular fibrocartilage complex injuries are common in amateur and professional sports.These injuries are mainly caused by acute or chronic repetitive axial loads on the wrist,particularly on the ulnar side and in association with rotations or radial/ulnar deviations.In order to treat professional athletes,a detailed specific knowledge of the pathology is needed.Moreover,the clinician should fully understand the specific and unique environment and needs of the athletes,their priorities and goals,the type of sport,the time of the season,and the position played.An early diagnosis and appropriate management with the quickest possible recovery time are the uppermost goals for both the athlete and the surgeon.A compromise between conservative vs surgical indications,athletes’needs and expectations,and financial implications should be achieved.Arthroscopic procedures should be timely planned when indicated as they could allow early diagnosis and treatment at the same time.Conservative measures are often used as first line treatment when possible.Peripheral lesions are treated by arthroscopic repair,whilst central lesions are treated by arthroscopic debridement.Further procedures(such as the Wafer procedure,ulnar osteotomies,etc.)have specific indications and great implications with regard to rehabilitation. 展开更多

AIM：To compare visual efficiency,specifically accommodation,vergence,and oculomotor functions among athletes and non-athletes.METHODS：A cross-sectional study on sports vision screening was used to evaluate the visual skills of 214elementary students（107 athletes,107 non-athletes）,aged between 13 and 16y.The visual screening assessed visual parameters such as ocular motor alignment,accommodation,and vergence functions.RESULTS：Mean visual parameters were compared between age-group matched athletes（mean age14.82±0.98y）and non-athletes（mean age 15.00±1.04y）.The refractive errors of all participants were corrected to maximal attainable best corrected visual acuity of log MAR0.0.Accommodation function assessment evaluated amplitude of accommodation and accommodation facility.Vergence functions measured the near point of convergence,vergence facility,and distance fusional vergence at break and recovery point.Ocular motor alignment was not statistically significant between both groups.Athletes had a statistically significant amplitude of accommodation for both the right eye（t=2.30,P=0.02）and the left eye（t=1.99,P=0.05）.Conversely,non-athletes had better accommodation facility（t=-2.54,P=0.01）and nearpoint of convergence（t=4.39,P〈0.001）when compared to athletes.Vergence facility was found to be better among athletes（t=2.47,P=0.01）.Nevertheless,non-athletes were significantly better for both distance negative and positive fusional vergence.CONCLUSION：Although the findings are still inconclusive as to whether athletes had superior visual skills as compared to non-athletes,it remains important to identify and elucidate the key visual skills needed by athletes in order for them to achieve higher performance in their sports. 展开更多
