| Abstract: | Abstract The effect of actively warming the forearm musculature on dynamic grip endurance was investigated by comparing the performance of the left and right hands, with or without warming-up, on a spring-loaded grip ergometer. There were 21 male subjects, aged 19 to 23. Warming-up consisted of 9 min. of four hand and wrist exercises conducted in 30-sec. bouts, at a rate of one repetition per sec., with 15-sec. intervals between bouts. This warm-up was shown to lead to temperature increases of between 1.6 C and 2.6 C in the flexor digitorum sublimis muscles of five subjects. Warming-up had no effect on grip endurance. |
