Gymnasts

Intelligent detection of athlete behavior is beneficial for guiding sports instruction. Existing mature target detection algorithms provide significant support for this task. However, large-scale target detection algorithms often encounter more challenges in practical application scenarios. We propose SCB-YOLOv5, to detect standardized movements of gymnasts. First, the movements of aerobics athletes were captured, labeled using the labelImg software, and utilized to establish the athlete normative behavior dataset, which was then enhanced by the dataset augmentation using Mosaic9...

Aesthetic athletes face higher risks of disordered eating, and perfectionism is one of the determinants involved. While research suggests that perfectionism in sport may play a role in physical and psychological well-being, its influence remains to be confirmed. As such, further examination of the influence of perfectionism on health is warranted as it could lead to better interventions. This preregistered research sought to shed new light on these relationships by investigating the mediating role of passion in the perfectionism-disordered eating relationship as well as physical and psychological well-being in aesthetic sports...

BACKGROUND: Sports practice during adolescence is important to enhance bone development, although it may provide different effects depending on the mechanical impact present in the sport. Besides, resistance training (RT) may also induce bone changes directly (via muscle contractions) and indirectly (via myokines). However, there have been no studies analyzing the longitudinal influence of engaging in sport with and without added mechanical load. Thus, this study aims to analyze the combined effects of sports participation and resistance training on areal bone mineral density (aBMD) accrual in adolescent athletes participating in swimming and impact sports for 12-months...

BACKGROUND: Hip arthroscopy has proved successful in treating femoroacetabular impingement syndrome (FAIS) in patients with and without borderline hip dysplasia (BHD). Despite a high prevalence of BHD in patients who participate in sports with high flexibility requirements, a paucity of literature evaluates the efficacy of hip arthroscopy in treating FAIS in flexibility sport athletes with BHD. PURPOSE: To compare minimum 2-year patient-reported outcomes (PROs) and achievement of clinically significant outcomes in flexibility sport athletes with BHD undergoing primary hip arthroscopy for FAIS with capsular plication with results in flexibility sport athletes without dysplasia...

PURPOSE: To describe serum irisin and fibroblast growth factor-21 (FGF-21) concentrations in healthy female adolescents with different training activity patterns and their associations with bone mineral properties and metabolic markers. METHODS: A total of 62 adolescent girls aged 14-18 years were recruited: 22 rhythmic gymnasts, 20 swimmers, and 20 untrained controls. Bone mineral characteristics by dual-energy X-ray absorptiometry, daily energy intake by dietary recall, serum irisin, FGF-21, undercarboxylated osteocalcin, and C-terminal telopeptide of type I collagen were measured in all girls...

INTRODUCTION: Synchondrosis ischiopubic syndrome (SIS), also known as Van Neck-Odelberg disease, is a benign skeletal abnormality in children due to delayed closure in the ischiopubic synchondrosis (IPS). Patients may present with vague groin, hip, or buttock pain that can cause limitation of hip movement or limp. Few descriptions of this disorder exist, and it can easily be mistaken for other pathologies, including stress fracture, osteomyelitis, or tumor. CASE REPORT: We report the case of a 9-year-old female gymnast presenting with right hip pain who was diagnosed with SIS...

BACKGROUND: Ulnar collateral ligament (UCL) reconstruction has been the standard surgical intervention for elite male athletes with UCL insufficiency. Recently, UCL repair and augmentation with an internal brace has been increasingly performed. PURPOSE: To evaluate the clinical and functional outcomes as well as return-to-sport rate after UCL repair in female athletes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Included were 15 female athletes (mean age, 16...

Increase in youth sports participation, longer duration of play, and earlier starting points have increased the prevalence of acute and repetitive overuse musculoskeletal injuries. This rise in injury rates has led to increased efforts to better understand the susceptible sites of injury that are unique to the growing immature skeleton. Upper extremity injuries are currently the best studied, particularly those that occur among pediatric baseball players and gymnasts. The weak link in skeletally immature athletes is the growth plate complex that includes those injuries located at the epiphyseal and apophyseal primary physes and the peripherally located secondary physes...

BACKGROUND: Osteochondritis dissecans (OCD) of the capitellum is a well-described condition that most commonly affects adolescent throwing athletes and gymnasts. There is no gold standard rehabilitation protocol or timing for return to sport (RTS) after surgical management of OCD of the capitellum. HYPOTHESIS/PURPOSE: The purpose of the study was to identify in the existing literature any criteria used for RTS following surgical treatment of OCD of the capitellum...

BACKGROUND: Stretching has garnered significant attention in sports sciences, resulting in numerous studies. However, there is no comprehensive overview on investigation of stretching in healthy athletes. OBJECTIVES: To perform a systematic scoping review with an evidence gap map of stretching studies in healthy athletes, identify current gaps in the literature, and provide stakeholders with priorities for future research. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 and PRISMA-ScR guidelines were followed...

The primary objective of this systematic review with meta-analysis is to methodically discern and compare the impact of diverse warm-up strategies, including both static and dynamic stretching, as well as post-activation potentiation techniques, on the immediate performance of gymnasts. Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this paper evaluated studies that examined the gymnasts' performance after different warm-up strategies namely stretching (static [SS] or dynamic), vibration platforms (VP) or post-activation, in comparison to control conditions (e...

BACKGROUND: Autograft palmaris has been the primary choice for the reconstruction of the medial ulnar collateral ligament (UCL) in the elbow. Agenesis of the palmaris tendon is not rare, and outcomes of allograft reconstruction in the breadth of athlete types found in the adolescent population are lacking. HYPOTHESIS: Allograft tendon reconstruction of the medial UCL in the young elbow would have low failure rates and satisfactory outcome scores. STUDY DESIGN: Case series; Level of evidence, 4...

This study examines the sleep health, diet quality, and lipid profile of A&T athletes clustered by their performance position. METHODS: Forty-two A&T athletes, clustered as tops ( n  = 19; age = 19.6 ± 1...

Action quality assessment (AQA) is to assess how well an action is performed. Previous works perform modelling by only the use of visual information, ignoring audio information. We argue that although AQA is highly dependent on visual information, the audio is useful complementary information for improving the score regression accuracy, especially for sports with background music, such as figure skating and rhythmic gymnastics. To leverage multimodal information for AQA, i.e., RGB, optical flow and audio information, we propose a Progressive Adaptive Multimodal Fusion Network (PAMFN) that separately models modality-specific information and mixed-modality information...
