Abstract
The purpose of this study was to clarify the effects of inter-set static stretching on force production and flexibility in multiple sets of multi joint exercise. Seven healthy men underwent static stretching of gluteus muscles and quadriceps femoris for 30 seconds each between 4sets × 12reps of back squats. The number of repetitions to the failure in the fifth set and the flexibility before and after back squats were measured. We found that the number of repetitions in the fifth set was greater and the flexibility was maintained compared to nonstretching. These results suggest that inter-set static stretching in multiple sets of back squats may improve the training effect.
