Brief Summary

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.
