Gymnasts perform handstands on various apparatus, both in stable and unstable conditions. Such performances require specific muscle activation, which should differ depending on the condition and expertise of the gymnast. Therefore, the aim of the study was to evaluate 1) the difference in electromyography (EMG) between handstands performed on three apparatus (floor, rings and parallel bars); and 2) the difference between young and well-trained adult gymnasts. Ten adult (25 ± 3.94 years) and 15 young (13.9 ± 0...

We compared postural control of expert gymnasts (G) to that of non-gymnasts (NG) during bipedal closed-eyes quiet standing using conventional and nonlinear dynamical measures of center of foot pressure (COP) trajectories. Earlier findings based on COP classical variables showed that gymnasts exhibited a better control of postural balance but only in demanding stances. We examined whether the effect of expertise in Gymnastic can be uncovered in less demanding stances, from the analysis of the dynamic patterns of COP trajectories...

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...
