摘要：Longitudinal bending stiffness (LBS) of footwear has been shown to affect performance in jum
ping and sprinting tasks. A detailed description of the mechanisms underlying the performance alterations is lacking in the literature at the moment. Therefore, the purpo of this study is to describe why performance in a linear acceleration task is affected by LBS. Fifteen male athletes were analyd using full-body motion analysis combined with ground reaction force (GRF) measurements during the first step of a full effort 5 m sprint in a low stiffness baline (BL), medium stiffness (MS) and high stiffness (HS) condition. A significant reduction in acceleration performance (6.3%) was found in the HS condition compared to BL. Changes in acceleration performance in MS and HS were related to altered contact times, ground force
