The practice of regular physical activity subjects the body to various physical stresses. Yet children have an immature skeleton that undergoes growth spurts, making them more susceptible to developing cartilage pathologies. The most common for the lower limb are Osgood-Schlatter's and Sever's.

Because footwear is at the body/ground interface, it is one of the main ways of limiting the impact of various physical stresses. It is therefore an essential element to take into account in the onset and therefore in the prevention of these pathologies.

During Alexis Herbaut's thesis (CIFRE LAMIH-Décathlon), it was shown that reducing the drop of the tennis shoe (difference in height between the heel and the forefoot) influenced the kinematics of the lower limbs of young athletes. Following on from this work, this thesis project, financed by Décathlon, aims to identify, biomechanically and functionally, the influence of the drop of the multi-activity shoe on the locomotion and development of young athletes. In this context, children were provided with shoes with different drops, which they had to wear during sports, school and leisure activities. Cross-sectional and longitudinal analyses of the children's motor skills should make it possible to characterize short- and long-term neuromuscular, biomechanical and functional adaptations in order to determine the most relevant footwear condition(s) to offer this young population.
