ABSTRACT |
Kim, K.B., Hong, K.D., Lee, D.C., Lee, S.W., Jun, T.W. Estimation of one repetition maximum by anthropometric measurements in weight training beginners. Exercise Science, 14(4): 495-504, 2005. Submaximal weights are used for estimation of repetition maximum(1RM) because there are risks of injury in musculoskeletal system during the measurement of 1RM. The purpose of this study was to compare estimates of 1RM by anthropometric measurements and 7-10RM in weight training beginners. The subjects were 40 weight training beginners (22.5±2.5 yrs) in male university students. The regression equation to predict 1RM of bench press was y=-55.349+1.56 (circumference of chest)+.665(grip strength)-.50(circumference of thigh) (R2=.587, F(1, 38)=17.064, p<.01). The squat was y=-15.056+1.139 (circumference of chest) (R2=.396, F(1, 38)=24.897, p<.01). We have expected that the R square of muscle mass was the highest value than any other variables, but it was excluded from regression model. Also, the correlation coefficients between 1RM and resting metabolic rate (RMR) was low. On the contrary, variables such as circumferences of chest and thigh, grip strength were included in regression model. We conclude that It is possible to predict 1RM by anthropometric measurements to some degree and the future studies should be considered variables of individual difference such as baseline of muscle strength, gender, age. |
