Purpose This study was to examine the effect of 60mg-pseudoephedrine on aerobic ability and metabolic function during graded treadmill exercise. Methods Six healthy, male, ordinary men attended to graded treadmill exercise. The subjects were given a graded exercise test(Bruce protocol), Then crossed over and re-started after one week. All data(i.e., O2 consumption, total work time, rating of perceived exertion, heart rate, systolic blood pressure, blood glucose, GOT, GPT, BUN, creatinine) were analyzed using a two tailed, paired t-test(p<.05). Results The level of blood glucose at the end of stage 3 with application of 60mg-pseudoephedrine was significantly higher than that without application of
60mg-pseudoephedrine(p<.05). The blood pressure at the end of stage 3 with application of 60mg-pseudoephedrine was significantly higher than that without application of 60mg-pseudoephedrine(p<.05). No other significant differences were observed at stages of submaximal exercise or recorvery. These data suggest that a recommending dose of 60mg-pseudoephedrine dose not enhance or impair VO2 and other cardiopulmonary variables and during submaximal exercise. Conclusions: On the base of these results, further research design should be followed to investigate the effects of 60mg-pseudoephedrine on other cardiopulmonary parameters during graded treadmill exercise |
