Countermovement jump and vertical hop demonstrate braking/deceleration and performance alterations after ACL reconstruction with BMA, DBM, and suture tape augmentation.

Objectives: This study evaluated countermovement jump and Single Leg Jump measures to identify landing measures that best distinguish a novel Anterior Cruciate Ligament reconstruction technique using bone marrow aspirate, demineralized bone matrix, and suture tape augmentation patients from controls. The secondary objective assessed performance differences between operated and non-operated limbs post-reconstruction. The hypothesis was that novel Anterior Cruciate Ligament reconstruction patients at return to sport would not differ from controls during landing and that the operated limb's performance would not differ from the unoperated limb. Methods: The study included 31 patients with the novel reconstruction technique matched with controls in a 1:10 ratio based on age, sex, weight, and height. Both groups underwent screening and were compared during a Countermovement Jump. Using a Sparta Science Force Platform, each patient's unoperated and operated limbs were also compared for Single Leg Jump post-op (6.5 months). Results: Test patients showed no difference in center of pressure during landing of both jumps compared to controls (P=0.27) and the uninvolved limb (P=0.26). Test patients exhibited increased braking impulse relative to the uninvolved limb during Single Leg Jump (P<0.001). Deceleration upon landing of Countermovement Jump was also increased compared to controls (P<0.001). Test patients demonstrated slower concentric time during a Countermovement Jump compared to controls (P=0.03) and significantly slower compared to the uninjured leg (P<0.001). Countermovement Jump height was decreased compared to controls (P<0.001). Single-leg jump height was decreased in the injured limb compared to the uninjured limb (P<0.001). Conclusions: Test patients did not show significant differences in landing motion compared to controls or the uninvolved leg. However, power and performance alterations were evident at Return to Sport after reconstruction. Although these results are quite promising, they may be too preliminary to draw definitive conclusions. Double and single-legged assessments should be considered in return-to-sport decision-making.

Relevance and quality of the Gipuzkoan extracurricular youth sports program: an evaluation from a positive youth development perspective.

Physical activity and sport (PAS) programmes are an important part of organized extracurricular activities for children and young people. They appear as potentially inclusive environments where students could be provided with holistic development based on active and healthy lifestyles. The aim of this study was to evaluate and describe the Gipuzkoa School Sport Programme (GSSP) from the positive youth development (PYD). The research was carried out based on CPAR (Critical Participatory Action-Research) methodology: a "CPAR group" was created -including researchers and policymakers- to carry out the evaluation of the GSSP in which we analyzed (a) the social environment or PYD climate and (b) life skills. The evaluation and description of the GSSP confirmed that it meets most requirements for providing positive development contexts and opportunities for PYD. The choice of prioritizing multisport and deliberate play and putting early specialization aside seem key conditions to ensure PYD-promoting environments. This work could serve as a referent for decision-makers in organizations dedicated to designing, developing, implementing, and evaluating PYD-focused extracurricular youth sport programmes.

Geriatric medicine and Olympic elite sports-parallels and philosophies.

The 30th Olympiad took place in July 2024. At first glance, sports science and training of elite athletes may appear to be of little relevance to geriatric medicine. However, there are important parallels between the practice of geriatric medicine and elite sports and lessons that we can learn from our sports science colleagues. Elite athletes and older people are operating at the margins of physiological capacity. Both benefit from tailored, scientifically informed training programmes delivered and monitored by a multidisciplinary team. There are parallels between the comprehensive geriatric assessment and the philosophy of marginal gains pioneered by British Cycling. Insights into the biology of skeletal muscle function are beginning to translate into the development of clinical interventions and substances that offer an unfair advantage in sport by improving muscle strength and physical performance may be of therapeutic benefit in sarcopenia. The 2024 Olympics provide an opportunity for us to learn lessons for excellence in our research and provide an opportunity to promote exercise across the life course-important for healthy ageing.

Relationship between screen-play scenarios' effectiveness and player classification in elite wheelchair basketball based on match results of Tokyo 2020 Paralympic Games.

Background: The competitiveness of wheelchair basketball has increased over time. However, screen-play, considered a vital offensive tactic in running basketball, is still poorly clarified. Therefore, this study aimed to clarify the impact of screen-play on scoring and game results in wheelchair basketball and assess the roles of each player classification (PC). Methods: Information regarding screen-play, including 13 categories such as shot success, location, and PC, was recorded for 22 wheelchair basketball games in the Tokyo 2020 Paralympic Games. This information was analyzed using the chi-square test to evaluate the significant differences in the appearance frequency of variables in each category (categorical variable) between the winning and losing teams and the shot-success rate. Results: Except for PC-related categorical variables, comparing the appearance frequency of the winning and losing teams confirmed a significant difference for screen and pass locations (all p < 0.05). Regarding the shot-success rates of the winning and losing teams, a significant difference in five categories was confirmed, including shot and pass locations (all p < 0.05). Regarding the PC, comparing the appearance frequency of the winning and losing teams confirmed a significant difference for PC of the screener (p < 0.05). Significant differences were found in the shot-success rates of the winning and losing teams in nine, five, three, and four categories regarding the PCs of the shooter, user, screener, and passer, respectively, such as shot location, pass location, and type of screen (p < 0.05, respectively). Conclusion: In wheelchair basketball offenses, it may be effective to consider the following points in the scenario lead-up to a shot: Using two different spaces, in the paint and the 3-point field goal area, could be crucial in screen-play. Improving the accuracy of on-the-ball screen plays appears vital, and using off-the-ball screens could also contribute to winning. Allocating approximately 50% of screeners to the middle-point classification (Middle) players and the rest to the low-point (Low) and high-point (High) classification players, at approximately 25% each, may be practical. Regarding winning team player roles, using High shooters and users; Low, Middle, and High screeners; and Middle and High passers contributed to play success.

Game schedule, travel demands and contextual factors influence key game-related statistics among the top European male basketball teams.

This study examined the effects of game schedule, travel demands and contextual factors on team game-related statistics during a full season. The top 10 teams competing in the 2020-2021 Euroleague basketball season were included where game-related statistics from their respective national competitions and the Euroleague competition were retrieved (761 games). Hierarchical linear regression models were computed to evaluate the effects of distance travelled, game schedule and contextual factors for the previous and current games (league, season phase, opponent level, game outcome, score differential) on key performance indicators (points, shooting, rebounds, assists, turnovers, fouls). Several significant models (p < 0.05) yielded R2 values ranging from 0.05 to 0.22 with small-to-medium effect magnitudes. Analyses revealed significant associations between longer durations separating games and less free-throws being made and between further distances travelled and worse 3-point shooting, more offensive rebounds and more fouls. Regarding contextual factors, favourable outcomes for shooting, assists, steals, fouling and turnovers were significantly associated with team success. Playing higher-level teams and competing in playoffs or finals was associated with several diminished outcomes. These results emphasize the multi-factorial nature of performance in elite European basketball, with game schedule, travel and various contextual factors requiring consideration in developing holistic operational plans for teams.

Consumer product-related female genital injuries in the USA from 2013 to 2022.

BACKGROUND: Consumer product-related genital injuries in females across all age groups are understudied. Existing research focuses primarily on paediatric populations. We aimed to determine characteristics, trends and predictors of hospitalisation. METHODS: The National Electronic Injury Surveillance System database was queried for female genital injuries from 2013 to 2022. We stratified our population into four age groups (<18, 18-34, 35-54, >54 years). Automated text matching and manual reviews were employed for variable extraction. χ2 tests and logistic regression were conducted, accounting for survey design and weights. RESULTS: 9054 cases representing a national estimate of 252 329 injuries (95% CI 188 059 to 316 599) were identified. Paediatric injuries were most common (61%) and seniors had the highest hospitalisation rates (28%). Falls were common in paediatric (51%) and senior (48%) groups, whereas self-induced and topical application injuries were more frequent among adults aged 18-34 and 35-54. Injuries predominantly involved playground equipment and bicycles in children, razors and massage devices in adults aged 18-34 and 35-54 and household structures in seniors. Hospitalisation increased over the decade from 7% to 9%; significant predictors of hospitalisation were Asian race (OR=3.39, 95% CI 1.83 to 6.30), fractures (OR=7.98, 95% CI 4.85 to 13.1) and urethral injury (OR=3.15, 95% CI 1.30 to 7.63). CONCLUSIONS: Our study identifies distinct patterns in female genital injuries across ages. In the paediatric cohort, injuries are often linked to playgrounds and bicycles. For adults, grooming products are frequently implicated. Seniors commonly suffer injuries from household structures such as bathtubs. These patterns may inform discussions on tailored preventive strategies.

The OMNIVEG STUDY: Health outcomes of shifting from a traditional to a vegan Mediterranean diet in healthy men. A controlled crossover trial.

BACKGROUND AND AIM: The Mediterranean diet is a plant-based dietary pattern with well-established health benefits such as the reduced risk of cardiovascular disease. Additionally, incorporating more plant-based foods into a Mediterranean diet may provide further health benefits. The study aimed to assess the effect of shifting from a traditional Mediterranean diet to a vegan Mediterranean diet on cardiorespiratory fitness and lipid profile in physically active and healthy men. METHODS AND RESULTS: Participants underwent a baseline period with adhesion to the general patterns of the Mediterranean diet for three weeks and then they changed to an isocaloric vegan version of the Mediterranean diet for four weeks, with a 7-day washout period between diets. The shift from the traditional Mediterranean diet to the vegan Mediterranean diet required substituting animal-based foods with plant-based foods that contain comparable amounts of protein and fat. Fourteen participants with a mean age of 24.6 ± 7.0 years (range: 18-37 years), completed the study protocol. The change from the traditional to the vegan Mediterranean diet reduced blood concentration of total cholesterol (-22.6 mg/dl, p < 0.01, Effect size [ES] = 1.07) and low-density lipoprotein cholesterol (-12.8 mg/dl, p < 0.01, ES = 0.72). An inverse correlation was observed between the intake of dietary fibre and LDL-C (partial rho = -0.43, p = 0.040). CONCLUSIONS: The adoption of a vegan Mediterranean diet with plant-based proteins and fats instead of the traditional Mediterranean diet improved several cardiometabolic health outcomes in physically active and healthy men. CLINICAL TRIAL REGISTRY: NCT06008886.

Understanding of head injury assessment and return to play processes and associated factors in United States Major League Rugby players.

OBJECTIVES: Evaluate professional rugby players' self-reported perceived understanding of the head injury assessment (HIA) and return to play (RTP) processes and determine factors related to understanding and trust pertaining to these processes. METHODS: An electronic survey measured concepts of interest. A thematic analysis of player understanding was performed, and player statements were coded. RESULTS: 207 U.S. Major League Rugby (MLR) players participated (26.7 ± 3.4 years). HIA and RTP protocol understanding was not correlated with concussion history (p = 0.41). International rugby experience and trust regarding MLR support of the following protocols and opposing team medical staff practices varied in their relationship to HIA understanding. Trust that all MLR teams follow the same protocols was positively correlated with all HIA questions (ps < 0.03). No HIA questions were correlated with trust in their own team's medical staff. All trust questions were significantly correlated with RTP process understanding. Qualitative analysis identified four HIA- and RTP-related themes: education needs, staffing needs, HIA criticisms, and importance of player safety. CONCLUSION: International playing experience and greater trust in the MLR and league stakeholders were associated with greater player understanding of the HIA and RTP protocols. These results provide insight into the importance of educating players on league-specific concussion protocols.

Physiotherapy Rehabilitation of Scapholunate Ligament Instability Following Ganglion Cyst in a Recreational Basketball Player: A Case Report.

Ganglion cysts are prevalent benign soft tissue tumors, commonly occurring on the dorsal wrist and often associated with underlying joint structures like the scapholunate ligament (SLL), a critical stabilizer of the wrist. SLL instability, frequently resulting from acute trauma or repetitive stress, can significantly impair wrist function, causing pain, reduced range of motion, and decreased grip strength. This case report details the conservative management of a 25-year-old recreational basketball player who presented with SLL instability and a dorsal ganglion cyst following two separate wrist injuries. Despite initial conservative management, the patient continued to experience persistent pain and functional limitations. Diagnostic imaging confirmed the presence of a ganglion cyst arising from the SLL, which necessitated a targeted physiotherapy regimen. The rehabilitation protocol focused on pain relief, wrist stability, muscle strengthening, and functional performance, employing phonophoresis, K-taping, laser therapy, and progressive strengthening exercises. Throughout treatment, the patient exhibited marked improvements in wrist range of motion, muscle strength, and pain reduction, ultimately returning to basketball activities without recurrence of symptoms. This case underscores the potential effectiveness of conservative physiotherapy in managing SLL instability with associated ganglion cysts, emphasizing the importance of a comprehensive, multifaceted approach to rehabilitation in restoring wrist function and enabling a return to sports.

Effects of inspiratory muscle training on lung function parameter in swimmers: a systematic review and meta-analysis.

Background: This systematic review and meta-analysis aimed to assess the impact of inspiratory muscle training (IMT) on lung function parameters (MIP, MEP, FEV1, and FVC) between both elite and non-elite swimmers. Methods: We searched for controlled clinical trials (CCT) and prospective longitudinal studies (PLS) in elite and non-elite swimmers following an inspiratory muscle training (IMT) protocol with a standardized device, published between 2012 and 2023. The databases used in the search were PubMed, Science Direct, Scopus, Springer, Cochrane Central Register of Controlled Trials, and Google Scholar. The primary outcome assessed was the impact of IMT on lung function parameters, including MIP, MEP, FEV1, and FVC. Results: We selected 13 articles involving 277 subjects aged 11-21 years, with 61.4% being male, and 84.6% being elite swimmers. The most commonly used IMT device was the PowerBreathe®, prescribed for 3-12 weeks, 1-2 sessions per day, 3-6 times per week, with 30 repetitions, starting at 50% of MIP and progressing up to 80%. The meta-analysis showed that IMT was associated with a higher MIP (MD = 29.35 cmH2O, 95% CI: 13.04-45.65 cmH2O, p < 0.01) without affecting FEV1 and FVC. Conclusion: The swimmers that used IMT improved muscle strength, specifically MIP, without changes in MEP, FEV1, and FVC.

Factors influencing the relationship between coaches and athletes with disabilities: a systematic review.

Introduction: The relationship between coaches and athletes with disabilities is critical for enhancing athletes' performance and psychosocial well-being. This study aims to provide evidence-based recommendations for coaches, sports organizations, and policymakers dedicated to supporting athletes with disabilities. Methods: A comprehensive analysis of existing literature was conducted. Five databases were searched, including PubMed, Web of Science, SPORTDiscus, Google Scholar, and China National Knowledge Infrastructure. A total of 22 studies were included for thematic analysis. Results: This systematic review identifies key factors influencing the coach-athlete relationship in disabled sports. These factors are categorized into three main domains: professional, interpersonal, and intrapersonal. In the professional domain, effective coaching requires sport-specific skills and adaptive techniques tailored to the unique needs of athletes with disabilities. Coaches must understand the technical and tactical aspects of each parasport and adapt training plans to optimize performance and foster independence. The interpersonal domain emphasizes communication strategies and team-building practices. Effective communication involves understanding athletes' needs and adapting approaches to maximize strengths. Building rapport, managing conflict, and fostering a supportive team environment are crucial for maintaining a positive coach-athlete relationship. The intrapersonal domain highlights the importance of self-reflection and continuous learning. Coaches who engage in self-reflection and professional development better understand their behaviors and biases, enabling them to tailor coaching strategies to the specific needs of athletes with disabilities. Continuous learning is essential for remaining responsive to the evolving needs of these athletes. Discussion: This review underscores the importance of a holistic approach that integrates professional expertise, interpersonal skills, and intrapersonal awareness. By addressing these factors, it provides a foundation for developing more effective coaching strategies and supports for athletes with disabilities, ultimately enhancing their performance and well-being. Future research should explore cultural differences, the specific coaching needs of athletes with intellectual disabilities, and the impact of policies and structural barriers on the coach-athlete relationship in disabled sports.

Peak tibial accelerations in different foot strike patterns during level running: an independent investigation in different cohorts.

Peak tibial accelerations are used to monitor impact severity during distance running and as input for bio-feedback. Here, peak tibial accelerations were compared between rearfoot and forefoot strikes. Two different studies were undertaken by independent research centres. Tibial acceleration and optical motion capture were collected in 14 rearfoot strikers who changed to a forefoot strike in the first centre. In the second centre, tibial acceleration of 14 other rearfoot strikers and nine forefoot strikers were collected and processed. In over-ground level running at a submaximal speed, the resultant peak tibial acceleration was greater in the instructed forefoot strike condition (ΔX = 7.6 ± 1.3 g, mean ± standard error difference) and in the habitual forefoot strikers (ΔX- = 3.7 ± 1.1 g) than in the rearfoot strikers. The shank kinematics revealed a greater decrease in antero-posterior velocity following touchdown in the forefoot strike condition. The forefoot strikes experienced greater posterior tibial acceleration, which resulted in an increased resultant peak tibial acceleration that also occurred earlier than in the rearfoot strikes. No significant difference in axial peak tibial acceleration was found between these foot strike patterns. In conclusion, the foot strike pattern differently affects peak tibial accelerations in level running, which can have implications for monitoring and biofeedback applications.

Human rights and the olympics: from an ideological paradox to a new anti-corruption legacy.

This article aims to explore the evolution of the debates surrounding human rights in the discourse(s) of major sporting events (MSEs), particularly the Olympics. The paper will first analyse the western-centric origins of the "universality" of the Olympic philosophy and how it affected the protection and promotion of human rights, as well as addressing practical challenges or limitations faced. It will then focus on unpacking the elements of sportswashing and soft power in the multi-discursive context of sport where power, privilege, politics, and position are (re)produced. In doing so it draws upon the emergent field of Sports Diplomacy as the most appropriate explanatory framework to share in this discourse. Finally, it will explore the potential impact of anti-corruption reforms on the establishment of a meaningful human rights legacy.

Physiological Insights From Asymptomatic Severe Valvular Disease in a Highly Trained Athlete.

Parameters relied on as tools for prognostication in valvular disease can be confounded by athletic physiological remodeling. This case describes how cardiopulmonary exercise testing and multimodality imaging may be helpful in assessment of a 46-year-old female athlete with bicuspid aortic valve and subaortic membrane with associated asymptomatic severe mixed aortic valve disease.

Sport and Autism: What Do We Know so Far? A Review.

Autism, or autism spectrum disorders, is a neurodevelopmental condition characterized by limitations in social interaction, communication skills, and repetitive behaviors. Although motor disorders were previously considered marginal in autism, recent research has highlighted their significance. Numerous studies have underscored the positive impact of sports on autistic individuals. This article presents a comprehensive overview of the literature regarding the effects of sport interventions on autistic individuals and aims to extract general and practical recommendations. Initially, the article reviews the various characteristics of autism that are positively impacted by sports, ranging from psycho-social skills to motor behavior. Subsequently, it examines how different configurations of sports practice (individual/collective, indoor/outdoor, etc.) may be suitable for autistic individuals. Literature research was conducted in two databases, resulting in the inclusion of 92 articles meeting longitudinal criteria (i.e., containing full sport/physical activity programs with pre-to-post analyses) out of 1665 initially identified articles. The findings suggest that individuals with autism can benefit from sports across a wide range of physical, psychological, and social factors. Importantly, there is no full contraindication for any activity, although some may require specific step-by-step preparation. Each activity has the potential to provide benefits in specific areas, as discussed in the article. In conclusion, further research is needed to explore the most effective strategies for implementing sports programs and maximizing their benefits for individuals across the autism spectrum.

Failure and complication rates following meniscal all-inside and inside-out repairs: A systematic review and meta-analysis.

PURPOSE: This study examines failure rates, complication rates and patient-reported outcome measures (PROMs) for meniscal all-inside (AI) and inside-out (IO) repair techniques. METHODS: A systematic search was conducted on PubMed, Embase and Cochrane (inception to January 2024) assessing for Level I-III studies evaluating outcomes after meniscal repair. The primary outcome regarded differences in failure rates between AI and IO repair techniques. Secondary outcomes included a comparison of complication rates and PROMs. Quality assessment was performed using the Grading of Recommendations Assessment, Development and Evaluation and Methodological Index for Non-Randomized Studies criteria. A meta-analysis was conducted for outcomes reported by more than three comparative studies. RESULTS: A total of 24 studies (13 studies and 912 menisci for AI vs. 17 studies and 1,117 menisci for IO) were included. The mean follow-up ranges were 22-192 months (AI) and 18.5-155 months (IO). The overall reported AI failure rate ranged from 5% to 35% compared to 0% to 25% within the IO group. When comparing meniscal repair failure rates in the setting of concomitant anterior cruciate ligament reconstruction, the AI group had a failure rate (AI: 5%-34%; IO: 0%-12.9%). The complication rate ranged from 0% to 40% for AI and 0% to 20.5% for IO. Post-operative PROM scores ranged from 81.2 to 93.8 (AI) versus 89.6 to 94 (IO) for IKDC and 4.0-7.02 (AI) versus 4.0-8.0 (IO) for Tegner. Upon pooling of six comparative studies, a significantly lower failure rate favouring the IO technique was observed (15.9% AI vs. 11.1% IO; p = 0.02), although this result was influenced by a study with a predominantly elite athlete population. Moreover, no significant differences were found regarding complication rates between cohorts (7.3% AI vs. 4.8% IO; p = 0.86). CONCLUSION: The present study underscores comparable clinical success between AI and IO meniscal repair techniques, with both techniques demonstrating similar complication rates. However, the AI repair technique was associated with 1.77 times higher odds of failure compared to the IO cohort. LEVEL OF EVIDENCE: Level III.

Sport mental health continuum in young Brazilian athletes: adaptation and psychometric properties.

Instruments used to assess the mental well-being of young athletes in Brazil are scarce. Therefore, the present study aimed to translate, cross-culturally adapt for young athletes, and gather evidence of validity for the Sport Mental Health-Short Form (S-MHC) for use in Brazilian Portuguese. The research was conducted in five stages: translation, synthesis, back-translation, expert review, and validation of the psychometric properties. For validation, 246 young athletes of both genders (88 females, 35.8%), aged between 12 and 18 years (14.5 ± 1.9 years), were recruited. Psychometric methods were employed to confirm and validate the translated and adapted versions of the S-MHC for young athletes, including internal consistency using Cronbach's alpha and McDonald's omega, composite reliability, Item Characteristic Curve (ICC) using Item Response Theory (IRT), and Confirmatory Factor Analysis (CFA). Two structures were tested, with Model 1 loading the 14 items of the translated version of the S-MHC into a single latent factor and Model 2 loading the items into three factors related to emotional, social, and psychological sport well-being. Both models showed good validity, consistency, and reliability measures and can be used to investigate the sport well-being of young athletes. It was concluded that the translated version of the S-MHC in Brazilian Portuguese can be used to assess the sport well-being of young athletes in Brazil. Model 2 structure is recommended to observe the different nuances of emotional, social, and psychological well-being.

Relationship Between Single-Leg Vertical Jump and Drop Jump Performance, and Return to Sports After Primary Anterior Cruciate Ligament Reconstruction Using Hamstring Graft.

Background: After anterior cruciate ligament reconstruction (ACLR), asymmetry is likely to persist in single-leg (SL) vertical jump and drop jump performance than in SL hop distance. However, its relationship with the return to sport (RTS) remains unclear. Hypothesis/Purpose: This study aimed to determine the association between vertical jump performance after primary ACLR using hamstring tendon autograft and RTS at a pre-injury competitive level. Study design: Cross-sectional study. Methods: Patients who underwent primary ACLR using hamstring tendon autograft were recruited for this study. Participants who returned to pre-injury competition after ACLR were recruited at least eight months postoperatively. Knee condition was assessed, including joint laxity, range of motion, muscle strength, and knee pain intensity during sports activities. Performance variables were also assessed, including SL hop distance, jump height in SL vertical jump, and reactive strength index (RSI; jump height/contact time) in SL drop jump. Participants were asked to subjectively report whether they had returned to the same level of competition as pre-injury and their perceived sport performance intensity. Those who answered "Yes" to the dichotomous question and had a postoperative subjective athletic performance of > 80% were categorized into the Yes-RTS group. The primary outcome was the ability to achieve RTS at the preinjury level. Results: Sixty-five patients (female, 35; male, 30) at 13.0 (13.0) [median (interquartile)] months after ACLR participated in this study. Thirty-nine (60%) were assigned to the Yes-RTS group. Regarding knee conditions, the No-RTS group had a significantly higher knee pain intensity, as assessed using a numerical rating scale (p<0.001, effect size -0.45). In the performance tests, the No-RTS group exhibited a significantly lower limb symmetry index of RSI during the SL drop jump compared to the Yes-RTS group (p=0.002, effect size 0.81). Conclusion: Patients unable to achieve RTS after primary ACLR using hamstring grafts are more likely to exhibit asymmetric performance during the SL drop jump test, suggesting the significance of assessing jump symmetry when evaluating post-ACLR rehabilitation success. Level of Evidence: 3c.
