Changes in Body weight and its Influence upon the Relationship between Static Strength and Reaction Time.

Abstract

This study aims to clarify whether body-weight influences upon the magnitude of the relationship between strength and reaction time as usually believed by many athletic leaders. Reaction time under three experimental conditions, (1) leg standing, R.T.,(2) leg sitting, R.T., (3) leg "weight-less" R.T., and the leg strength of fifty young men, with an average age of 22, were recorded during one testing session. It appears to be true that correlation between reaction time and strength are too low to be used as a basis for the prediction of individual differences in reaction time from a knowledge of the subject's strength scores.
