Filter by:Objectives : To determine intra and inter-subject sprinting performance modifications with trademarked Carbon-made spiked-Shoes (CS) compared to usual carbon-free ones (Standard spiked-Shoes-SS). Methods : Design. Multiple N-of-1 trial (Alternating Treatments Design), with block randomisation and double blind procedure. For each participants, sixteen repetitions of 30m-sprint are applied either with CS or SS, in random order for each repetition, during a 3h session a day. Blind procedures are reached by applying a dark sleeve cover on each shoes, and by separating raters from investigators. Patients. Regional to National healthy sprinting athletes (750 IAAF/WA points), affiliated to the French Athletics Federation among the South Regional Athletic League (Comité du Var-FFA), are recruited as volunteers, with their own CS (from the same brand for homogeneity and generalisation concerns) and SS. Main criteria. Time on a 30-meters sprint, with Force-Velocity Profiling (FVP) procedure, using Stalker Sport radar. Secondary outcome measures. F0, V0, Vmax, Pmax , DRP and other standard FVP parameters, also measured with MySprint software; morphometric and cinematic data ; mean price difference between the two models. Statistical analyses. A block randomisation model will be applied to check for the randoms size; variance analysis with a mixt linear model will be applied for group and confounding factors analysis. Student-T test and NAP will be applied for intra-individuals analysis.
Purpose: To explore the sports performance of the adolescent sprinters, including analyzing the correlations between the results and central nerve sensory, and also between motor control and various muscle mechanical characteristic and sport-related fitness factor.
Few studies indicate that sprint performance may be impaired in football players with a previous hamstring strain injury. This exploratory cross-sectional study aim to compare sprint performance between football players with and without a previous hamstring strain injury. The findings may elucidate potential indications of insufficient rehabilitation following a hamstring strain injury. Sprint performance data will be collected using the MySprint Iphone Application. Due to pragmatic reasons and the exploratory nature of this study the aim is to include players on a team level. Based on the prevalence of hamstring strain injuries the expected number of cases to be included are 10-20 football players with a previous hamstring strain injury, and a corresponding 80-90 number of healthy controls. No outcomes will be weighted (flat outcome structure).
