Number of repetition after different rest intervals between static stretching and resistance training

Abstract Objective The purpose of this study was to investigate the effects of different intervals between static stretching for hip adductor, quadriceps and hamstring muscles and resistance training in repetition performance. Method Twenty-two trained men were submitted to the 10 repetition maximum test and retest for leg extension, leg curl and hip adduction exercises. Three protocols were conducted in a randomized design – PWI: resistance training immediately after static stretching; P15: fifteen-minute rest interval between static stretching and resistance training; P30: thirty-minute rest interval between static stretching and resistance training. Results The total number of repetition [(sets * repetitions) + exercises] performed under P30 (84.55 ± 1.68) was significantly higher than P15 (79.73 ± 1.89) and PWI (68.09 ± 2.03), respectively. Significant differences were also found between P15 and P30. Conclusions Therefore, 30-minute interval between static stretching and resistance exercises was needed to achieve greater repetition performance. Thus, static stretching for lower limbs may be avoided before a resistance training session.
