The purpose of this study was to determine the effect of stretching after cardiovascular exercise on hamstring flexibility. Twelve students (ages 18-21 yrs) enrolled in a cardiovascular activity class were measured for hamstring flexibility using the sit-and-reach test. Subjects were randomly divided into a stretching group (SG, n = 6) and a no stretching group (NS, n = 6). Both groups participated in various cardiovascular endurance training activities for 20 minutes/day, 2 days/week for 12 weeks. SG performed hamstring stretching exercises for 5 minutes following their cardiovascular work. SG made a significant 4.6% increase while NS showed only a 0.9% difference. However, due to the large variability in each group, there was no significant difference between SG and NS in their improvement in sit-and-reach performance. Group effect size suggests that stretching exercises following a cardiovascular exercise session may improve sit-and-reach flexibility to a greater degree than no stretching.
