Determination of static contraction times to exhaustion for given percentages of a 1 Rm in the bench press, leg press, and pulldown exercises
The purpose of this study was to determine the time to exhaustion based on percentages of the 1 RM in the bench press, leg press, and pulldown exercises. Eleven healthy males, age 27.7 +/- 5.5 years, volunteered for the study to compare the strength differences between their maximum isotonic strength and isometric strength (a static contraction hold) in the pulldown, bench press, and leg press exercises. Five randomized static contractions sets were performed 5 cm below the lockout position in the bench press and leg press exercises. The static contraction position for the pulldown was when the forearm was at a 90Ã‚Â° angle relative to the upper arm. The percentages of the static contraction sets were based on the time to exhaustion normally associated with weight/strength training. The results indicate that greater loads can be used for longer contraction times during the static contraction sets than conventional, full range movements.
