Stress fractures are common overuse injuries in athletes, especially in long-distance runner, jumping sports and gymnastics in female athletes. The pathology of stress fracture mainly includes repeated biomechanical loading, which leads to bone micro-damage and failure of bone structure. Female athlete triad(FAT), which includes low energy availability with or without an eating disorder, functional hypothalamic amenorrhea, and osteoporosis, is a serious healthcare concern in female athletes. For prevention and treatment of stress fracture, management of biomechanical factors modifying the load applied to a bone is important, and especially in female athletes, management for FAT is one of the important factors...

INTRODUCTION: Teaching acrobatic skills with a minimal amount of repetition is a major challenge for coaches. Biomechanical, statistical or computer simulation tools can help them identify the most determinant factors of performance. Release parameters, change in moment of inertia and segmental momentum transfers were identified in the prediction of acrobatics success. The purpose of the present study was to evaluate the relative contribution of these parameters in performance throughout expertise or optimisation based improvements...

Massage and medical gymnastics experienced a rapid institutionalization across Europe and North America between 1850 and 1914. This article explores how this process took place in London and Paris. Physiotherapy developed many of the hallmarks of an independent discipline during this period, including an identified corpus of manipulations and exercises, some autonomous training courses and degrees for future practitioners, and even the creation of departments within several hospitals. The article analyzes all of the processes surrounding this rise, paying special attention to the influence of the ambassadors of Swedish gymnastics (which led to the re-invention of massage across Europe), to the installation of physiotherapy in hospitals in London and in Paris, and to the practical and institutional innovations driven by nurses in England and by doctors in France...

OBJECTIVES: Current trends among young athletes towards earlier specialization age and year-round training on multiple teams has raised concern for increased injury risk. Our previous analyses showed higher risk for injury in highly specialized young athletes. The goal of this research was to determine whether sports specialization and injury patterns vary by sports type. METHODS: In this clinical case-control study, injured athletes (aged 7-18 years) were recruited from sports medicine clinics and compared to similarly aged uninjured athletes recruited from primary care clinics...

BACKGROUND: Osteochondritis dissecans (OCD) lesions are often observed in the humeral capitellum both in young baseball players and gymnasts. It is generally believed that capitellar OCD in baseball players can be seen on an anteroposterior (AP) radiograph with the elbow in 45° of flexion. However, the mechanism of injury seems to be different in baseball players and gymnasts. Repetitive valgus overload with the elbow in flexion is believed to be the cause of capitellar OCD lesions in baseball players, whereas weightbearing with the elbow in extension may be the cause of OCD in gymnasts...

When judging performances in a sequence, the current score is often influenced by the preceding score. Where athletes are perceived to be similar, a judgement is assimilated towards the previous one. However, if judges focus on the differences between the two athletes, this will result in a contrasting influence on their scores. Here, I investigate sequential effects during synchronized diving events at the 2012 and 2016 Olympic Games. Although previous research found assimilation in scores of gymnasts, the current data showed contrast effects-current scores benefited from following a poor performance but were at a disadvantage if they followed a high-scoring performance...

Clinical Scenario: CrossFit is a form of exercise that incorporates rapid and successive high-intensity, ballistic movements. As CrossFit becomes an increasingly popular fitness option, it is important to determine how rates of injury compare to more traditional forms of exercise. This review was conducted to ascertain the incidence of injury with CrossFit relative to other forms of exercise. Focused Clinical Question: Are injuries more common with CrossFit training than other forms of exercise? Summary of Key Findings The literature was searched for studies that compared injury rates among individuals who participated in CrossFit fitness programs to participants in other exercise programs The search initially yielded >100 results which was narrowed down to three level 2b retrospective cohort studies that was deemed to have met inclusion/exclusion criteria In all three reviewed studies, the reported incidences of injuries associated with CrossFit training programs were comparable or lower than rates of injury in Olympic weightlifting, distance running, track and field, rugby, or gymnastics...
