we investigated the effects of inter-set rest versus static stretching on repetition performance, maximum heart rate, and blood lactate concentration during biceps curl exercise. Twelve resistance-trained male participants completed five sets at 75% of one-repetition maximum (1RM) under two different inter-set conditions: passive rest and static stretching. We observed that static stretching significantly enhanced repetition performance from the second to the fifth set, compared to passive rest. While maximum heart rate showed no statistically significant difference between the two methods, a trend toward higher heart rate was noted in the static stretching condition. Both methods resulted in elevated post-exercise blood lactate levels, with no significant difference between them. These findings suggest that static stretching between sets may serve as an effective strategy to maintain performance during resistance training by alleviating fatigue. We propose static stretching as a practical and accessible recovery technique for athletes and practitioners seeking performance improvements in training contexts.
