초록

This study was to examine whether relationship between step test and maximal oxygen uptake in college females.Twelve healthy subjects in SM women's university were participated in this study. The subjects were assigned three groups according to their body mass index before experiment.All exercise testing was performed on a treadmill (modified Bruce protocol) in the laboratory. During the test, heart rate was monitored by an ECG and ratings of perceived exertion(RPE) were asked of subjects every 3 min to help identify progressive fatigue and subsequent exhaustion. The step tests(cadence: 30steps/min, duration: 5 min) of 20, 30 and 40 cm were conducted to measure the physical efficiency index and 800m running was examed using a standing start method. The data were analyzed by the SPSS programs of analysis of multiple correlation, and analysis of multiple linear regression. There were significant relations between maximal oxygen uptake and physical efficiency index(30 and 40cm step height). These results indicate that combined bench stepping of 30cm and 40cm heights can indirectly measure maximal oxygen uptake of college females.
