초록
The purpose of this study was to investigate the effects of resting periods betweenexercise sets during isokinetic contraction on recovery from muscle fatigue, strength,heart rate, blood pressure, and lactate level. Sixteen women performed 10 repetitionsof isokinetic exercise for three sets in three different conditions. During the sets,they rested 50, 100, and 150 seconds in each condition. And the results were:1) In thispopulation, the peak torque of extensor during the isokinetic exercise in 100 secondresting condition was significantly higher than that in 50 and 150 second restingconditions (p<.01). The total work of extensor was significant in the secondand third sets in 50 and 100 second resting conditions (p<.01. 2) During theisokinetic exercise, the heart rate was progressively increased as the sets were advancedin all resting conditions (p<.01). And the increased was significant during the second andthird sets than the first in 50 second resting conditions (p<.01), while it was significantlygreater after the third set than the first in 100 and 150 second resting conditions (p<.01).4). No difference was found between the resting periods in blood lactate level and bloodPressure during the isokinetic exercise. However, differences were found betweenthe sets in these variables
