Aim: The aim of this paper was to to assess the 1RM responses of individuals with and without experience in resistance training.
Methods: Fifty four healthy men were distributed into two groups: 1) group T, subjects with experience in resistance training (N.=28); 2) group NT, subjects without experience in resistance training (N.=26). All subjects performed six 1RM sessions with 48-hour intervals between sessions for following exercises: biceps curl, 45º leg press, chest press and pulley. All 4 exercises were performed in the same day with rest intervals of 5 minutes in between each exercise.
Results: The body mass index (BMI),%fat and lean body mass (LBM) were higher in the NT group than in the T group (P<0.001). There were no changes in maximum force through the course of the test sessions in group T. Nevertheless, the NT group showed increments (P<0.001) of absolute workload, workload indexed to the lean body mass and a percentage increase between the 1st and 6th test in all segments: increments of 37% in biceps, 38% in the supine, 40% in pulley and 44% in leg press were found.
Conclusion: Individuals without experience in resistance training exhibited improvements of maximum voluntary dynamic strength with the increase in the number of test sessions, indicating the effect of familiarization and learning. Moreover, it was found that individuals with experience in weight training needed only one session of 1RM tests to obtain the maximal voluntary dynamic force in the different types of exercises used.
