EFEITO DO INTERVALO ENTRE SESSÕES DE EXERCÍCIO DE FORÇA SOBRE O DESEMPENHO NEUROMUSCULAR EFFECT OF INTERVAL BETWEEN STRENGTH EXERCISE SESSIONS ON NEUROMUSCULAR PERFORMANCE EFECTO DEL INTERVALO ENTRE SESIONES DE EJERCICIO DE FUERZA SOBRE EL DESEMPEÑO NEUROMUSCULAR

1 (Biologo) ABSTRACT Introduction: The rest interval between bouts is a crucial variable of resistance training to ensure recovery of neu- romuscular capacity. Objective: To compare the effect of rest interval between repeated bouts of resistance training on neuromuscular capacity of trained men. Methods: Eight resistance-trained men (21.6 ± 3.3 years, 75.1 ± 11.3 kg, 178.2 ± 6.8 cm) performed two randomized and crossover resistance exercise bouts, repeated with rest interval of 24h or 48h. The bouts consisted of horizontal, inclined and declined bench press performed with five sets of 10 repetitions with an intensity of 70% of one repetition maximum (1RM) for each exercise. Neuromuscular performance post-exercise bout (strength, power and speed), was assessed with an accelerometer (Myotest ® ), with a load of 50% 1RM, in the bench press exercise. Results: Both sessions (24 and 48h) showed significant reduction (P 0.05). Conclusion: The results suggest that the rest interval of 24h is sufficient for recovery of neuromuscular performance in upper limbs of resistance-trained men.
