Reduction of cutaneous sensory feedback of the soles of the feet decreases maximum vertical squat jump height

This study examined the role of cutaneous sensory feedback on the soles of the feet for a maximal motor output task. Participants performed maximum vertical squat jumps (MVSJ) under baseline, cooled, and recovered conditions. MVSJ height, jump preparation average force and impulse were lower in the cooled condition compared to baseline and recovered conditions, while contact time was greater between cooled and baseline. These results suggest cutaneous sensory feedback plays a critical role in maximal vertical jumping.
