【 摘 要 】

The purpose of this study was to determine the validity of the 2redictedmaximal MET equations on the Schwinn Air-Dyne bicycle ergometer for apopulation of females between the ages of 19 and 29 years. Twenty-fivefemale Ss volunteered to take part in the study. Twenty-one of the 25Ss reached a V02 max (l/min) that was defined by 1 of 2 criteria for a;;true;; maximal test. Predicted maximal METs were compared to measuredn~aximal METs obtained while exercising on the Schwinn Air-Dyne. Twoheart rates were obtained during an 8-minute submaximal test. Predictedmaximal METs were determined for each subject in an equation that usedan age predicted maximal heart rate and the two submaximal heart rates.The ;;true;; VO, max test was used to determine measured maximal METs. APearson product-moment correlation and paired t-test revealed a highpositive correlation (r - .88) and a significant difference between themeans of predicted maximal METs and measured maximal METs (p < .05).The difference between the means of predicted and measured maximal METswas 4.6%. Predicted maximal METs underestimated measured maximal METsby 0.56 METs. The predicted maximal MET equations were thereforeconsidered to be valid for determining maximal METs for purposes otherthan research.
