Effects of the Singapore Youth Shoulder Overuse Injury Prevention Program Among Youth Volleyball Athletes in Singapore
The Singapore Youth Shoulder Overuse Injury Prevention Program (YoSO-IPP) includes an exercise segment and an education segment. This study will (1) assess the effects of the exercise segment, and (2) assess the effects of the education segment among youth volleyball athletes using a randomized controlled trial over 12 weeks. Performance outcome measures of shoulder eccentric external rotation strength, shoulder internal rotation range of motion, and thoracic rotation range of motion will be used to assess the effects of the exercise segment. Knowledge scores via an online questionnaire will be used to assess the effects of the education segment.

Hypothesis: The YoSO-IPP will have an effect on shoulder eccentric external rotation strength, shoulder internal rotation range of motion, and thoracic rotation range of motion and on knowledge scores.
