This study aimed to identify physique characteristics (anthropometry, somatotype, body proportionality) of Brazilian female artistic gymnasts, and to compare them across competitive levels (sub-elite versus non-elite) within competitive age-categories. Two hundred forty-nine female gymnasts (68 sub-elite; 181 non-elite) from 26 Brazilian gymnastics clubs, aged 9-20 years and split into four age-categories, were sampled. Gymnasts were assessed for 16 anthropometric traits (height, weight, lengths, widths, girths, and skinfolds); somatotype was determined according to Heath-Carter method, body fat was estimated by bioimpedance, and proportionality was computed based on the z-phantom strategy...

Gregory D Schroeder, Alexander R Vaccaro
Cervical spine injuries are common and range from relatively minor injuries, such as cervical muscle strains, to severe, life-threatening cervical fractures with spinal cord injuries. Although cervical spine injuries are most common in athletes who participate in contact and collision sports, such as rugby and American football, they also have been reported in athletes who participate in noncontact sports, such as baseball, gymnastics, and diving. Cervical spine injuries in athletes are not necessarily the result of substantial spine trauma; some athletes have chronic conditions, such as congenital stenosis, that increase their risk for a serious cervical spine injury after even minor trauma...

REVIEW
Vladimir B Issurin
Extensive findings related to nature and nurture in determining athletic talent (AT) have been reviewed. Available data demonstrate the important contribution of hereditary factors as well as the crucial importance of environmental prerequisites for identifying and developing AT. Recent publications provide examples of contemporary approaches intended to solve the problem of how to discover and nurture AT. A number of cross-sectional and longitudinal studies highlighted possibilities of revealing a predisposition to certain sports among youthful prospects, but were unable to predict attainment of world-class status...

Dislocation of the posterior tibial tendon is an uncommon condition. Although surgery is usually performed in most cases of posterior tibial tendon dislocation, postoperative repeat dislocation of the posterior tibial tendon has not been reported in the published data. We report the case of a 27-year-old male patient who experienced repeat dislocation of the posterior tibial tendon after a gymnastic landing, 44 months after initial retinaculum repair. For revision surgery, we reconstructed the flexor retinaculum in conjunction with deepening of the retromalleolar groove, because the groove was hypoplastic...

The importance of technique selection on elbow injury risk has been identified for the key round off skill in female gymnastics, with a focus on the second contact limb. The aim of this study was to shift the focus to the first contact limb and investigate the biomechanical injury risk during parallel and T-shape round-off (RO) techniques. Seven international-level female gymnasts performed 10 trials of the RO to back-handspring with parallel and T-shape hand positions. Synchronized kinematic (3D motion analysis system; 247 Hz) and kinetic (two force plates; 1235 Hz) data were collected for each trial...

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...
