The injury risk inherent to soccer can be affected by external training loads and intrinsic factors. These intrinsic factors (sex, mass, strength, coordination, etc.) in young athletes can be rapidly altered the near their peak height velocity (PHV) during puberty, modifying their movement complexity and, potentially, their injury risk. While quantification of movement complexity through multiscale entropy analysis have been used in past biomechanical investigations, no studies have incorporated this analysis on tibial accelerometry signals collected in these maturing athletes. The purpose of this study is to collect tibial acceleration data from youth soccer athletes during several discrete drills and …

Background: The main purpose was to evaluate individual kinematic characteristics in highly trained sprinters during the „set” position, block clearance and a 20-m acceleration phase, as well as to determine differences and/or technique similarities. Material/Methods: The measurements were carried out on two sprinters, members of the Polish national team. A wireless portable MyoMotion system (Noraxon Inc., USA) was applied. Angular changes and accelerations of all limbs, trunk and head were measured. Results: Increased motion asymmetry between sides brought about stride fluctuation and worsened sprint performance. This effect occurred when the sum of the discrepancies for hip, knee and ankle joints …
