简要总结
The purpose of this study to to compare the long-term effects of foam rolling in comparison to static stretching and a control group on hamstring flexibility. The investigators hypothesize that participants in the foam rolling and static stretching group will demonstrate increased flexibility to the control group, but will a difference will not be observed between the foam rolling and static stretching groups.

- •Current involvement in a lower extremity flexibility program outside of their regular activity
研究组 & 干预措施
Foam rolling
Participants in the foam rolling group will perform unilateral rolling of the hamstring musculature from ischial tuberosity to posterior knee in supine for 2 repetitions of 1 minute with 15 second rest between repetitions at a consistent cadence of 1 second superiorly and 1 second inferiorly. Subjects will be asked to adjust pressure as needed to maintain a consistent moderate pressure on the treatment area. Participants will use new and individually issued high density foam rollers that are 6" diameter x 36" length.
干预措施: Foam Rolling (Other)
Static stretching
Participants in the static stretching group will perform sustained static hamstring stretching for 2 repetitions of 1 minute bouts for the same leg before switching sides using moderate pressure in supine against the wall. Subjects will rest for 15 seconds between repetitions and adjust distance from the wall to perceive moderate intensity.
干预措施: Static Stretching (Other)
Control
The control group will perform their regular baseline activities without the addition of a specific lower extremity flexibility program. If the subjects are currently performing stretching of any mode at baseline, they will be allowed to continue with that activity.
