Effects of Strength Training on Musculoskeletal Overuse Injuries in Female Runners

Not Applicable

Completed

• Conditions: Overuse Injury

• Registration Number: NCT03080246
• Lead Sponsor: Wake Forest University Health Sciences

Brief Summary

The purpose of this study is to look at the effect of strength training in preventing overuse injuries in female runners

Detailed Description

This randomized clinical trial will compare the effects of 9-months of strength training to a control group on: (1) injury rates in female runners during the 9 month intervention period, and for 9 months after completing the intervention, and (2) on the potential mechanisms of injury including strength, joint and tissue loading, and psychosocial factors.

Primary Outcome Measures

Name	Time	Method
Incidence of Overuse Injury (Physical Exam/Injury Report Form)	Month 18	To compare the effects of a 9-month strength training program to a control group on the incidence of overuse, lower extremity, running injuries in female adult recreational and competitive runners during and 9 months subsequent to the training period.

Secondary Outcome Measures

Name	Time	Method
