Effects of Arm Ergometry Exercise on the Reaction, Movement and Response Times of the Lower Extremities.
Israel, Richard G.
A study determined the effects of fatigue produced in the upper extremities on the reaction time, movement time, and response time of the lower extremities in 30 male subjects, 19-25 years old. Each subject participated in a 10 trial practice session one day prior to the experiment and immediately preceding the pre-test. The pre-test consisted of four trials with 15 seconds between each trial. One minute after the termination of the progressive arm ergometry exercise, post-test, recovery 1, 2, and 3 reaction time treatments were administered. A single group design ANOVA with repeated measures indicated that reaction, movement, and response times were significantly faster during the pre-test than during the post-test, recovery 1, 2, or 3, while there were no significant differences between mean times for post-test, recovery 1, 2, or 3. The ANOVA for trial effects during the third trial were significantly faster than during the first trial, while there were no significant differences between other trials. It was concluded that heavy physical fatigue produced in the upper extremities transferred to the lower extremities and significantly impaired the whole body reaction time, movement time, and response time and that this deteriorative effect remained during acute recovery.
