Clinical Trial Summary

Evaluation of a neck strengthening program as a potential intervention to reduce the risk of sport-related concussion in youth contact and collision sport athletes.

Description:

This is a pilot study to investigate the effect of a supervised 8 week strengthening intervention in male and female youth contact and collision sport athletes. Participants will complete a supervised strengthening exercise intervention involving manual resistance exercises administered by a strength coach with pre- and post-intervention assessments of neck size and strength.
