The study on Estimation of maximal oxygun uptake through PWC%HRR during Arm Ergometer Exercise. Exercise Science, 9(1): 1-12, 2000. The purpose of this study was to evaluate the validity for estimation of maximal oxygen uptake through PWC%HRR during Arm Ergometer Exercise. The subjects of this study were 20 healthy males(21.2±2.77yrs) college students. Resting heart rate of subjects were recorded by EKG for 5min. the maximal oxygen uptake was determined until subjects were exhausted. The first stage was performed 50rpm, 20W, and then was increased by 10W every 3 minutes on the arm ergometer. HRmax was determined by a numerical formula of HRmax = 210-age. PWC%HRR was assessed by relative equation (Y=bX+a) of HR and V˙O₂ observed in range 120≤R≥160 during the exercise test. Range of relative percentage was between 50% and 85%, comparison factor was examined among PWC%HRR, % V˙O₂R and % V˙O₂_(max). The results of this study are as follows : 1) Result of the regression analysis among PWC%HRR, % V˙O₂R and % V˙O₂_(max), %HRR was equivalent to % V˙O₂R rather than V˙O₂_(max). 2) No significant difference was observed among PWC%HRR, % V˙O₂R and V˙O₂_(max) in the all intensity, But the PWC%HRR was closer to % V˙O₂R rather than V˙O₂_(max)(P<.05). 3) No significant difference was the actual V˙O₂_(max) and the estimation value by PWC%HRR = % V˙O₂R in the all intensity, and the correlation analysis was the most correlated at the estimation value by PWC%60HRR. It was concluded that if the satisfactory V˙O₂_(max) was not found in Arm Ergometer exercise test but heart rate corresponded to 60%HRR, V˙O₂_(max) can be estimated by a series of equation.
