1 Published in 2017 at "European Journal of Applied Physiology"

DOI: 10.1007/s00421-017-3782-y

Abstract: PurposeMuscle cooling impairs maximal force. Using needle electromyography (EMG) to assess motor unit properties during muscle cooling, is limited and equivocal. Therefore, we aimed to determine the impact of local muscle cooling on motor unit… read more here.
