The purpose of the study was to examine the effects of age on isometric knee extension force control abilities. A second purpose was to investigate the effects of feedback and force level on force control abilities. A third purpose was to examine the relationship between submaximal force control abilities and self report scores of physical activity. Force control abilities were assessed in 20 younger (YA. mean age 26 yrs) and 20 older (OA: mean age 72 yrs) healthy adult males. The Cybex 6000 in conjunction with Lab VIEW, the Cardia physical activity survey, and the Yale physical activity survey were used for data collection. For force control testing, participants were instructed to maintain isometric knee extensor strength at three levels of submaximal strength (20% MVC, 60% MVC, and 24 ft-lbs.) within a specified bandwidth (+ 4.5 ft-lbs.) with and without visual feedback. The effects of age, force level, and feedback condition were examined on the primary dependent variables of index of force instability, bias, and time in bandwidth. Multivariate analysis of variance testing was used to examine the effects of age, target, and force level on the primary variables. A Pearson product Moment correlation was used to examine the relationship between force control and physical activity. OA, compared to YA, performed as precisely but had a higher safety margin (OA: -2.3 ft-lbs., YA: -3.7 ft-lbs.,) in the force control tasks. The YA, compared to the OA, had a significantly higher instability index (YA: . 19, OA: .11). The two groups had similar times in bandwidth. Both groups’ force control abilities diminished similarly with increasing force level and when feedback was removed. Finally, moderate physical activity had a statistically significant correlation with bias (.36) and with time in bandwidth (.40) Older adults free of neuromuscular, skeletal, and cardiovascular pathologies display similar force control abilities as young healthy adults. Future research should examine the relationships between force control and activities of daily living more extensively.
