Description

In this study we used a bicycle ergometer and analyzed the influence of different pedal rates on oxygen intake (VO2/W) and mean arterial pressure (MAP). The subjects were 14 young healthy men and the pedal rates were set as 60 rpm and 80 rpm. The method was 25 minutes exercise including 3 minutes rest and 5 minutes warm-up (W-up). The exercise intensity was set as constant heart rate load with an objective heart rate of (220 - age) × 0.6, and VO2/W and blood pressure were measured in every minute of rest, W-up and 20 minutes exercise. Then, 20 minutes of exercise with constant heart rate load was divided into 4 stages, one stage for every five minutes, and the mean value of each stage was compared VO2/W at 80 rpm was significantly higher in stage 1, and MAP at 80 rpm was significantly lower than at 60 rpm in every stage. Therefore, it is thought that exercise at 80 rpm can be performed with better efficiency and safety.<br>
