Aging
Study compared isometric contractions of young and old men and women
January 25th, 2005
Researchers have investigated the influence of aging on sex differences in muscle fatigability. According to recent research published in the Journal of Applied Physiology, "The purpose of [our] study was to compare time to task failure for a sustained isometric contraction performed at a submaximal intensity with elbow flexor muscles by young and old men and women." S.K. Hunter and colleagues of Marquette University in Milwaukee explained, "Twenty-seven young (14 men and 13 women, 18-35 yr) and 18 old (10 men and 8 women, 65-80 yr) adults sustained an isometric contraction at 20% of maximal voluntary contraction torque until target torque...
