Abstract

The aim was to investigate the impact of freediving fin parameter on the diver for two different foot morphologies, one without deformation and other with a hallux valgus. It proposes to identify the parameters that have the greatest influence on the stresses applied to the ankle. A complete experimental design with 4 factors was set up. The factors studied were the length of the fin, the stiffness, the water channelling system and the angle between the blade and the liner. A prosthetic foot was used to realise reproducible test in pool. It was fitted with strain gauge at the ankle. 16 fins were tested for the two-foot morphologies. ANOVA test were used to discriminate the most influential parameters and define if they are the same for both morphologies. The most influential factor was the angle between the liner and the blade (p
