Effect of maximal grip strength and initial grip strengthen contraction time and on areas under force-time curves during isometric contractions

Abstract Thirty subjects volunteered for a study designed to investigate the usefulness of force-time curve areas as determinants of endurance. With the termination point being 50% of maximum voluntary contraction, the effect of varying the initial strength of contraction was studied. In addition, correlations among maximum grip strength, area under force-time curves, and time of sustained isometric contractions were examined No significant differences were found in force-time curve areas across test conditions, while means for time were different. Strongest correlations were found among the force-time curve areas. Thus, because of the greater consistency of force-time curve areas over time alone, it was concluded that force-time curve areas should be considered as a useful alternative tool for those researchers dealing with handgrip endurance.
