Although previous studies have shown that stretching can increase range of motion and affect performance, the comparison of the effects on flexible and nonflexible adults is not clear. Therefore, the purpose of this study was to determine how flexible and nonflexible adults responded to a lower extremity mobility routine focusing on the hip and ankle joints. A randomized treatment experimental design was used in which subjects had their hip and ankle ranges of motion, lower body flexibility, countermovement vertical jump, and sprint performance assessed. They were then randomly assigned to one of two treatment orders for hip (n=9) or ankle (n=6) stretching before the same measurement outcomes were assessed again immediately after completing the treatment. The second treatment was completed at least 2 days later. The percent change of pretest to posttest range of motion, flexibility, and performance measurements were not significantly different between flexible and nonflexible adults after both a hip and an ankle stretching/mobility session.
