Metabolic and physiological responses of three methods of strength training in trained women

Abstract

Objective: Analyze the acute effects of the alternate repeat, bilateral fixed series and unilateral fixed series methods in trained women.

Methodology: The research was composed by 10 female individuals with at least 4 years of bodybuilding practice. Each one of them did a 4 days try-out, which the first day evaluate the maximum load, and the other days concluded the alternating regressive repetition (RRA), bilateral fixed series (SFB) and unilateral fixed series (SFU). Total time, repetitions performed, blood lactate, maximum heart rate, pain perception and effort using the Borg and Omni scales were measured.

Results: There was a significant difference (p < 0,01) in the repetition between the methods: SFB - 41,4 ± 9,40; SFU - 79,1 ± 13,3 e RRA - 72,0 ± 0,0.  And total time RRA with 114 seconds, 77 and 150 seconds difference for SFB and SFU respectively. In the other analyzes, no significant difference was observed between the methods.

Conclusion: The present research didn’t find any significant difference in the blood lactate, volume, Borg and Omnis cales between the methods. However, there was a significant difference in the time variation of the alternating regressive repetition method for the others.
