简要总结
This randomized controlled trial aims to explore the effect of a foot strengthening protocol on toe flexion strength, foot deformation and morphology as well as kinetics during sprinting, cutting and jumping in healthy athletes (18-40 completed years). The study consists of a 4 weeks control period, followed by 8 weeks intervention period and 4 weeks follow up
详细描述
During the first period participants are unaware of their allocation, while in the intervention period they will be allocated to a train intervention or a control group (habits maintenance). The primary outcome is the toes maximal voluntary isometric plantarflexion. The treatment effectiveness estimand is the same as in a pretest-posttest case control study, considering the end of the control period as pre-point. An estimation of the individual variability in response to the treatment will be provided.

结局指标
主要结局
maximal isometric joint flexion muscle strength MTP (in N)
时间窗: Change from baseline to Week 18
It will be measured using an ergometer composed of a 3-dimensional force sensor (Nano 25, ATI Industrial Automation, Garner, NC) during the 3 periods of the randomized controlled trial (control, intervention and follow-up) and repeatedly each week during the intervention protocol.
