Regression analysis of one repetition maximal strength from a 7∼10, 11∼15 repetition submaximal strength test in untrained 20s men

ABSTRACT

Maximal strength is calculated by measuring 1RM. Measuring 1RM is very important for exercise prescription. This study attempted to develop indirect estimation method using submaximal intensity of 7~10RM and 11~15RM with 20s novices. Eighty one of early and middle 20s students were involved this study. The simple regression was calculated by measuring 1RM, 7~10RM, and 11~15RM of bench press, dead lift, squat, chest press, lat pull down, leg press, and leg curl. At result, 1RM bench press(kg) =7.015+1.077×(7∼10RM); =19.017+1.045×(11∼15RM), 1RM dead lift(kg) = 1.195+1.207×(7∼10RM); =21.651 +1.124 ×(11∼15RM), 1RM squat(kg) =10.922+1.074×(7∼10RM); =29.214+1.013×(11∼15RM), 1RM chest press(kg) =8.544 +1.081×(7∼10RM); =17.170+1.165×(11∼15RM), 1RM lat pull down(kg) =3.640+1.158×(7∼10RM); =9.930 +1.254×(11∼15RM), 1RM leg press(kg) =19.127 +1.050 ×(7∼10RM); =34.896+1.096×(11∼15RM), and 1RM leg curl(kg) =22.901+0.848×(7∼10RM); =34.110 +0.783×(11∼15RM). The regression calculated through this study would be used as data to estimate 1RM of untrained 20s novice adult male from 7~10RM and 11~15RM. It is recommended to use 7~10RM which shows higher accuracy rate of estimation than 11~15RM.
