The purpose of this study was to determine work output during the performance of pull-up, push-up and sit-up exercises. In addition, the study was designed to gather pertinent data concerning the reliability and influence of the distance and resistance factors used in the work output computations.

A test and retest consisting of eleven anthropometric measurements and the performance of one pull-up, one push-up and one sit-up was administered to a non-probability sample of thirty-eight male physical education majors at the University of North Dakota. Work output was computed using the distance and resistance factors determined by the anthropometric measurements. Reliability estimates were established by correlating test-retest scores. All eleven measurements and the work output figures were 4eemed reliable with the lowest r value being .98.

It was found that the resistance factor correlated higher with the work output than did the distance factor for the pull-up and sit-up exercise while the opposite was true for the push-up.

The work output during each exercise varied considerably from individual to individual thus pointing out a major drawback to the common use of repetitions alone as a basis for measuring student performance in pull-up, push-up and sit-up exercises.
