Behavior of physiological parameters and the effectiveness of self-selection of load in bench press
Abstract
There is currently a great interest in resistance training in gyms and clubs, popularizing and making it a modality of physical effort for both men and women. This interest increased the number of students enrolled, which required greater attention from teachers. Traditional training prescription models are no longer efficient for a large number of interested parties. Thus, prescribing training using the 1RM methodologies and training zones became unfeasible, another model emerged: the self-selection of load. The objective of the study was to evaluate the effectiveness of the methodology of self-selection of load for 10 maximum repetitions (10RM) in the bench press exercise in two executions and to compare the behavior of the anthropometric, cardiovascular, subjective fatigue in the effort and biochemical parameters before and after the accomplishment of the same. The study consisted of 14 volunteers, male, 25.1±5.9 years, 6 months of muscle hypertrophy training and performed 3 tests, 1RM and two 10RM. Load, %1RM, number of repetitions, cardiovascular parameters, glycemia and OMNI were analyzed. When comparing the 10RM tests, it was observed that in the 2nd test a percentage of 55% of success in the self-selection of loads in relation to the 1st 10RM. No significant differences were observed between the studied parameters. The authors concluded that self-selection of load is an important tool in prescribing training in bodybuilding gyms, but it requires learning.
