Influence of local temperature on motor unit behavior during rapid contractions in humans.

ABSTRACT:

Purpose

The rate of torque development (RTD) is temperature dependent, but the temperature effects on motor unit behavior during rapid contractions remain largely unknown. This study aimed to clarify the influence of local limb temperature on motor unit behavior and RTD during rapid contractions in humans.

Methods

Ten healthy male participants rested in a sitting position while immersing their right lower leg in water at different temperatures (Hot: ~43 °C, Neutral: ~33 °C, and Cold: ~10 °C) for 20 min each. The participants then completed a series of voluntary isometric contractions of dorsiflexors while maintaining water immersion in each temperature condition. Specifically, they were instructed to perform two maximal voluntary contractions (MVC) followed by six rapid-hold
