About

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

Full description

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.

Enrollment: 30 patients

Sex: All

Ages: 18 to 40 years old

Volunteers: Accepts Healthy Volunteers
