BACKGROUND: The objective of this study was to investigate the influence of training status on the maximum number of repetitions possible when performed by two groups of men with different overall resistance training experience using different types of exercises performed at submaximal intensities.
METHODS: Twenty resistance-trained men were divided into two groups according to their resistance training experience: very experienced and less experienced. Both groups performed the 1 repetition maximum test on the bench press and 45º leg press on two different days. Volunteers randomly completed the maximum number of repetitions possible at 40% or 80% of 1RM test 48-72 hours apart.
RESULTS: There was no significant difference in the maximum number of repetitions completed between groups (P<0.05). However, comparison of the maximum number of repetitions performed between the two types of exercises at the same intensities within the same group revealed significant differences: more repetitions could be performed for leg press than bench press.
CONCLUSIONS: Training status did not affect the maximum number of repetitions completed at 40% and 80% of 1RM on bench press and 45º leg press exercises, while the type of exercise influenced the maximum number of repetitions performed by both groups.
