Abstract
PURPOSE: To assess how accurately Division II NCAA football players can predict repetitions-to-failure (RTF) during the bench press exercise using an absolute load of 225-lbs by comparing predicted repetitions-to-failure with actual repetitions-to-failure. METHODS: Twenty football players (age 20 ± 2 years; height 1.85 ± .06 m; weight 110.1 ± 19.3 kg) without muscular or skeletal injuries were tested for their 1repetition maximum (1-RM) in the bench press, and then performed 1 set to concentric failure with 225-lbs. Subjects predicted how many repetitions they could perform after the warm-up and again after the fourth, eighth, twelfth repetitions. A general regression analysis was used to determine the relationship between predicted repetitions-to-failure and actual repetitions-to-failure after the warm-up and after the 4th, 8th, and 12th repetitions. Additionally, the relationship between predicted- and actual-repetitions-to-failure and 1-RM after the warm-up and after the 4th, 8th, and 12th repetitions was determined using a general regression analysis. RESULTS: The general regression equation indicated significant positive relationships between predicted- and actual repetitions-to-failure after the warm-up & after the 8th and 12th repetitions (p < .05). A significant relationship was not found between predicted- and-actual-repetitions-to-failure after the 4th repetition (p < .05). Significant positive relationships were found between actual and predicted repetitions-to-failure after the warm-up and 1-RM and after the 4th repetitions (p < .05); however significant relationships between actual- and predicted repetitions-to-failure were not found after the 8th & 12th repetitions (p < .05). DISCUSSION: Subjects were more accurate in predicting repetitions-to-failure in the latter half of the set. This may be due to fatigue influencing their physiological and physical protective mechanisms or a learned effect from experience in weightlifting. CONCLUSION: It may be possible for Division II NCAA football players to regulate volume during the 225-lb bench press test; however it is not supported by the current investigation to use the RTF scores to predict 1-RM.
