Does the instruction influence voluntary force production regardless of gender during a handgrip exercise ?
Résumé
The aim of this study was to compare the results ofmaximal voluntary contraction (MVC) and
maximal rate of force development (MRFD) in women andmen during handgrip exercise
performed following three different instructions:Oral instruction (OI):Started with audible tripping
andaccompanied by encouragement during the whole muscle contraction. Triggered instruction
(TI): Same as oral instruction, but without encouragement. Self-initiated instruction (SI): The
subject himself decided to start and to stop the contraction.Women’s MVC and MRFD withOI
were higherthan SI. No significant differencehas been found between instructions in men. Our
results suggested that women are more sensitive to the instructioneffect compared to men. Further
explanations will be proposed using surface EMG and fMRI measurements.
