Programme C. Performance, croissance et sexe

Mon thème de recherche principal porte sur l’étude de la plasticité des systèmes neuromusculaire et métabolique à l’exercice aigü et chronique (entraînement) au cours de la  croissance et la maturation. L’originalité de ce thème réside en la manière dont ces systèmes s’adaptent et interagissent aux contraintes de l’activité physique chez l’enfant en fonction du stade de développement et du sexe. Ces connaissances sont fondamentales afin d’optimiser la performance sportive future de l’enfant à l’âge adulte mais aussi prévenir le risque de blessures au cours de la croissance.

Enfant, Croissance, Activité Physique, Santé, Performance, Fatigue, Physiologie.
