Comparison of Treadmill and Cycle Ergometer in Male Korean College Students
1999
Background : Generally max is higher in treadmill exercise than cycle ergometer exercise. According to Hassen and Wasserman, max with treadmill exercise is higher at ratio of 1.11 than that with cycle ergometer. max also is influenced by race, sociocultural background, exercise habit In this study, max and AT were evaluated between Treadmill and cycle exercise in male Korean college students. Method: Study subjects were 44 male college students. We randomized them into 2 groups; 24 students did treadmill exercise at first and 1 week later did cycle ergometer. Another 20 students did in opposite method. They made symptom limited maximal exercise. Author defined maximal exercise as followings: 1) respiratory exchange ratio(RER)> 1.1, 2) plateau>30 sec, 3) heart rate reserve(HRR) max and AT was /kg/min and /kg/min in treadmill and /kg/min, /kg/min in Cycle Ergometer. The measured-/pred- was in treadmill; in cycle ergometer. Comparing max in treadmill with that obtained by Hassen's method, there were significant differences.(p/pulse, BR, /MVV, between treadmill and cycle but not in , Vd/Vt, Ti/Ttot. At AT there were differences in /pulse, BR, /MVV, Ti/Ttot between treadmill and cycle, otherwise not. Conclusion: According to the result of this study, there are larger gap between treadmill and cycle ergometer in normal Korean adults than foreign data, and it needs further study to obtain reference value of Korea.
