BACKGROUND The injury rate in soccer is high, and studies have shown that the injury rate among players aged 16 years or older approaches that of adult players. However, little is known about the injury risk among the youngest players, that is, players between 6 and 12 years. PURPOSE To examine the risk of injuries in children 6 to 16 years old playing organized soccer. STUDY DESIGN Descrip...

BACKGROUND To the authors' knowledge, no study has investigated the concurrent repeated, high-intensity (RHIA) and repeated-sprint activity (RSA) of intermittent team-sport competition. PURPOSE In this study, they report on the RSA of elite women's football competition. In addition, they describe the nature of RHIA (eg, striding and sprinting activities) that involve a high energy cost and ar...

The aim of this study was to compare the physical performance profile among young soccer players of different competitive levels. Two teams of elite (n = 22) and sub-elite (n = 22) soccer players at national (highly skilled) and regional (moderately skilled) level were recruited in the study. All participants were tested using a modified Illinois change of direction speed test, a T-drill with a...

Abstract Cardiac modifications to training are a product of the genetic pre-disposition for adaptation and repetitive haemodynamic loads that placed on myocardium. Elite pre-adolescent athletes exposed high-intensity at young age with little understanding physiological clinical consequences. It is unclear how right ventricular (RV) structure function may respond this type stimulus. The aim stud...

The purpose of this study was to determine whether anthropometric, physical, psychological, and skill test results could be used to discriminate between male junior volleyball players of varying ability. A total of 66 elite and nonelite male Estonian volleyball players aged 16–17 years were measured for anthropometric and physical variables and sport-specific skills. In addition, the players’ p...

conclusions there was a higher incidence of genu varum in soccer players than in control adolescents; the stress and load imposed on the knee joint led to more severe genu varum. results both soccer players and controls had genu varum. however, the incidence of genu varum was higher in the soccer players (p = 0.0001) and it was more prevalent in the 16-18 year age group (p = 0.0001). the result...
