Abstract

The purpose of this study was to compare the effectiveness of the O'Connor Test and an absolute endurance test for predicting the maximal weight that can be lifted in the leg press exercise. Subjects were 101 untrained to moderately weight trained females aged 18-30. Each person performed a 1-repetition maximum leg press, an absolute muscular endurance, and the O'Connor test with a minimum of 48 hours between each test. The absolute endurance test consisted of a weight that was lifted as many times as possible to the cadence of 60 beats per minute. The test was terminated when the subject could not keep pace with the beat. Intraclass reliability coefficients for the 1-RM (R = .93) and the endurance test (R = .95) were high. However, due to the poor reliability (R = 0.39), no analysis was done on the O'Connor test. Results of a multiple regression analysis showed that leg press absolute endurance can be used to predict 1-RM leg press (SEE = 45.90 lbs). When body weight was added, the results changed by only a pound (SEE = 44.12 lbs) . The correlation between the measured and predicted leg press strength was R = .64 and when body weight was added, R = .67. The results of this study suggest that absolute muscular endurance tests may provide an alternative to the one-repetition maximum in assessing maximal lifting capacity.
