Abstract

The objective of this study was compare the number of repetitions achieved 80% of 1RM between single and multiple joint exercises for the chest and compare the number of repetitions achieved with the number predicted by the literature for the intensity of 80% of 1RM. We selected 10 menyears (22.3±2.6,Kg 74.9±11.1,cm 176.9±4.9) engaged in resistance training, which carried a maximum grade of 80% of 1RM until concentric fatigue. The exercises were pack deck fly and the bench press. The number of repetitions achieved in pack deck fly (10.4±2.0) was higher than in the bench press (8.3±2.3), but no significant difference was found. By comparing the repetitions of the exercises by the number of repeats expected in the literature, the pack deck fly showed a significantly greater number of repetitions. Therefore, the determination of exercise intensity by percentage of 1RM should not be used to prescribe strength training.
