Abstract
The purpose of study was to investigate the effect of oxygen supplemental (40%) in prior to exercise on apparent oxygen consumption (VO2peak) and maximal workload (Wmax), and to compare apparent oxygen consumption (VO2peak) and maximal workload (Wmax) between normoxia (21% O2) and oxygen supplement (40% O2). Twelve healthy males, age range 18 to 23 years, were randomly assigned to maximal exercise test with vacates 2 time in each time different oxygen breathing conditions at pre-exercise period; all subjects will breathed oxygen condition gas (21%O2 or 40%O2) for 10 min at rest and then exercise for 2 min at 0 W. The workload was increased by 20 W every 1 min until exhaustion. The parameters were measured at before, about 2 min during exercise and at the end of exercise. It was found that HR of 40%O2 at 120,160,200 watt and the workload at the end of exercise was significantly lesser than with 21%O2. The RR of 21%O2 was significantly lower than 40%O2 at 200 watt. The VO2 and VCO2 at 0 watt after 21%O2 were significantly higher than that of after 40%O2. The VE was no statistically different. The RER at 40 watt of 21%O2 was significantly lower than 40%O2. SaO2 of 21%O2 was no statistically different. At 200 watt, RPE of 21%O2 significantly lower than that 40%O2. At the end of exercise, VO2peak and Wmax of 21%O2 were increased significantly than 40%O2. The time to exhaustion was no statistical differences. Paired samples t-test be used to evaluate significant differences in all variable parameters of all conditions (P<0.05). In conclusion, it showed VO2peak and Wmax were not changed when compare between groups. But receiving the oxygen supplemental at pre-exercise period decreases heart rate during exercise, by does not effect on other performances. A further study is needed to explore other variables parameter such as blood circulation, when receiving oxygen in another period of exercise, in major muscle.
