Abstract

The purpose of this study was to establish the one-repetition maximum (1RM) prediction equations of biceps curl, bench press, and squat from the submaximal skeletal muscle strength of 4-10RM or 11-15RM in older adults. The first group of 109 participants aged 60-75 years was recruited to measure their 1RM, 4-10RM, and 11-15RM of the three exercises. The 1RM prediction equations were developed by multiple regression analyses. A second group of participants with the similar physical characteristics to the first group was used to evaluate the equations. The actual measured 1RM of the second group correlated significantly to the predicted 1RM obtained from the equations (r values were from 0.633 to 0.985), and standard error of estimate ranged from 1.08 to 5.88. Therefore, the equations can be utilized to predict 1RM from submaximal skeletal muscle strength accurately for older adults.
