|Abstract ||:||The purpose of the study was to examine the influence of hyperoxic gas (60% 02 in N_2) inhalation on performance of anaerobic exercise. Five male and five female university students measured IRM (one repetition maximum) of bench press exercise using Olympic barbell, and then a load (39.8±20.2 kg : 72.5±2.9% IRM) of performance test was decided. Subjects performed pench press (1 repetition/3 sec) until exhaustion while breathing air (normoxic condition : NOX) or a hyperoxic gas (hyperoxic conditiion : HOX) on two separate occasions. The hyperoxic gas was inhalated for 30 min before and during exercise. The number of repetition of bench press were 14.2±4.5 repetitions in NOX and 15.6±4.4 repetitions in HOX, that increased significantly by 9.9% (p<0.01) with hyperoxia. Eight of the ten subjects increased the number of repetitions during hyperoxia than with normoxia. There was no difference in the exercise time per repetition between NOX (3.5±0.5 sec/repetition) and HOX (3.5±0.6 sec/repetition). Peak concentration of blood lactate after exercise were 3.30±0.75 mmol/l in NOX and 3.36±0.95 mmol/l in HOX, these showed no difference. The results of this study suggest that hyperoxia may enhance the performace of anaerobic exercise.|
