The purpose of this investigation was to compare partial range of motion versus full range of motion training in the development of maximal strength. The bench press was used as the criterion measurement. The study was conducted over a 10-week period with training sessions occurring twice per week. Subjects were divided into 3 groups. Group 1 (N = 11) trained with 3 full range of motion sets on the bench press. Group 2 (N = 15) trained with 3 partial range of motion sets. A partial repetition was defined as one that is beyond the sticking point 2 to 5 inches from full extension of the elbows. Group 3 (N = 30) trained with a combination of partial and full range of motion sets. All subjects were pre- and posttested on the bench press through a full range of motion using a 1 repetition maximum. Each of the 3 groups demonstrated statistically significant increases in strength from pre- to posttest. No differences were found between groups. These findings appear to suggest that partial range of motion training can positively influence the development of maximal strength. Therefore, those involved in the strength and conditioning profession can confidently including this method as an adjunct to their normal training protocols when working with individuals similar to those found in this investigation. It is suggested that additional research be conducted to further establish the effectiveness of partial range of motion training in developing maximal strength.
