Voluntary Task Performance. a Grasp force: percentage of maximum pulling force exerted by pulling on lever bar. b Grasp time: time spent grasping and exerting force on the lever bar. c Reach rate: number of partial and full pulls on lever bar per minute. d Success rate: percentage of successful reaches of all reaches per day. e Duration of voluntary task participation: Time spent participating per day, in minutes, with 120 min per day as the target. Grasp force, success rate and duration of task participation were lower in 10-wk HRHF+TM rats, compared to 10 wk. HRHF rats (**:p < 0.01 each). There was no significant difference (ns) between the two groups for grasp time and reach rate. Mean + 95% CI is shown for 10-wk HRHF rats (n = 8) and 10-wk HRHF+TM rats (n = 5)
