Systematic aerobic exercise and components of reaction time in older women.
Reaction time and its fractionated components were studied in two groups of older women who differ in their level of regular aerobic exercise. Significant group differences were found in all dependent variables indicating that in older women regular aerobic exercise is an important factor influencing the speed of their reactions to simple and discriminatory stimuli, and in the accompanying premotor time, contractile time, and speed of movement following the reaction responses.
