Physical Activity, Physiological, and Psychomotor Performance: A Study of Variously Active Older Adult Men

Abstract

This research examined varying levels of physical activity and psychomotor and physiological function in variously active older men. Very active, moderately active, and low active participants were tested on simple (SRT) and choice reaction time (CRT), coincidence-anticipation timing (CAT), and VO₂max. No significant differences for age or height were found, although percentage of fat, and weight were statistically different. Active groups were leaner and lighter. VO₂max was significantly different between groups, as physically active groups yielded greater values. SRT and CAT also yielded significantly different results with more active participants showing better performance. No between-groups significant differences resulted for CRT. Generally, increased levels of physical activity were related to superior physiological outcomes and improved psychomotor performance.
