Abstract: Evidence from recent studies on animals and humans suggest that neural overflow from the primary sensory cortex (S1) to the primary motor cortex (M1) may play a critical role in motor control. However, it is unclear if whole-body maximal motor tasks are also governed by this mechanism. Maximum vertical squat jumps were performed by fifteen young adults before cooling, then immediately following a 15-minute cooling period using an ice-water bath for the foot soles, and finally immediately following a 15-minute period of natural recovery from cooling. Jump heights were, on average, 3.1cm lower immediately following cooling compared to before cooling (p=3.39 x 10-8) and 1.9cm lower following natural recovery from cooling (p=0.00124). Average vertical ground reaction force was also lower by 78.2N in the condition immediately following cooling compared to before cooling (p=8.1 x 10-5) and 56.7N lower following natural recovery from cooling (p=0.0043). The current study supports the S1-to-M1 overflow mechanism in a whole-body dynamic jump.
