摘要：The purpose of this study was to examine how circulatory responses are influenced by changes in angular velocity during isokinetic trunk rotatory exercise.Eight healthy adult males performed exercises at three different angular velocities, 60° /s, 90° /s, and 120° /s, for 20 sec each, and their heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean blood pressure (MBP) were measured. It was found that DBP was significant higher during the exercise at the angular velocity of 120° /s than during that of 60° /s and that SBP was also significantly higher during that of 120° /s than those of 60° /s and 90° /s. There was a significant difference in recovery time for HR between the exercises at the angular velocities of 60° /s and 90° /s, and 60° /s and 120° /s. Recovery time for both DBP and MBP was significantly longer after the exercise of 120° /s than after that of 60° /s. These results suggest that the exercise at the angular velocity of 60° /s may be the optimum exercise, putting the least burden on the circulatory system. However, in case the exercise is applied to patients with circulatory diseases, careful consideration will be necessary for the length of exercise period.
