Study Groups

Sleeper Stretch

Group Type EXPERIMENTAL

Sleeper stretch

Intervention Type BEHAVIORAL

Participants will complete their regularly scheduled workout activities over 8 weeks, with the addition of the sleeper stretch into the dynamic warm-up. Participants will be instructed to lie side-lying with the dominant arm downward, the trunk rotated posteriorly 20 to 30°, the shoulder raised to 90°, the elbow flexed to 90°, and both knees semi-flexed to ensure stability. Participants will then be asked to use the opposite hand to grasp the dominant hand below the wrist and gradually internally rotate the forearm towards the floor; (i.e., the participant will perform passive internal rotation with the opposite arm). This stretch position will be completed on both sides. Participants will be instructed to complete 2 sets of 10 repetitions for each arm and hold the position for \~2 seconds.

Control Group

Group Type ACTIVE_COMPARATOR

Standard workout

Intervention Type BEHAVIORAL

Participants will complete their regularly programmed dynamic warm-ups before scheduled workout for 8 weeks.
