Torque significantly decreased across the 120 s sustained MVC in all conditions (Control, continuous line; Hot, dashed line; hot head cool, dotted line). $Significant decrease throughout the contraction, P < 0.05. The higher decrement in torque observed in Hot and HHC is linked to a decrement in the level of voluntary activation (VA) in these conditions. *Hot and HHC lower than Con, P < 0.05. N.S., not significant.
