Efeito agudo da ordem de exercícios tradicional e pré-exaustão no treinamento de força

Abstract

Introduction: Different orders in exercise sequences during resistance training can affect neuromuscular performance. Objective: To investigate the effect of resistance training exercises (pre-exhaustion and traditional) on the performance and muscle activity of pectoralis major (PM) and triceps brachii (TB) during execution of bench press (BP) and triceps extension (TE) exercises. Methods: The sample was composed by 14 trained men (age: 25±4 years, height: 175±4 cm, weight: 80±11 kg). The experiment was carried out in two sessions. In the first, familiarization and determination of 10 repetition maximum (RM) of BP and TE exercises were carried out. The second was divided in two phases. The first evaluated exercise performance separately (control condition, CON). The second evaluated two different exercise orders: pre-exhaustion, PE (TE and BP) and traditional, TRAD (BP and TE). Performance and muscle activity of PM and TB were evaluated. One-way ANOVA was used to compare conditions. ANOVA (2x3) of repeated measures was used to compare muscle activity. Results: The results showed a smaller number of RM on TE in TRAD condition in comparison to CON and PE. It was observed a smaller number of RM in BP exercise in PE condition in comparison to CON and TRAD. As to the muscle activity evaluated by integrated electromyography, no significant differences have been observed as to PM and TB during execution of both exercises in all conditions. Conclusion: It was concluded that in both strategies the number of RM performed in the second exercise was reduced, however alterations were not observed in the activation of the main muscles in each exercise.
