Overuse Injury
Conditions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| Biomechanical Joint Moments (3D kinematic and kinetic data collected by 6-camera motion capture gait analysis) | Month 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on hip, knee, and ankle joint moments during running at the conclusion and 9 months subsequent to completion of the intervention. |
| Biomechanical Joint Forces (3D kinematic and kinetic data collected by 6-camera motion capture gait analysis) | Month 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on knee and ankle compressive and shear bone-on-bone joint forces during running at the conclusion and 9 months subsequent to completion of the intervention. |
| Biomechanical Joint Tissue Loading (3D kinematic and kinetic data collected by 6-camera motion capture gait analysis) | Month 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on joint tissue loading during running at the conclusion and 9 months subsequent to completion of the intervention. |
| Self-Efficacy (Adherence Self-Efficacy Questionnaire) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on performance self-efficacy at the conclusion and 9 months subsequent to completion of the intervention |
| Lower Extremity Muscular Strength (HUMAC norm isokinetic dynamometer) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on lower extremity muscular strength at the conclusion and 9 months subsequent to completion of the intervention. |
| Quality of Life (Satisfaction with Life Scale) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on health-related quality of life at the conclusion and 9 months subsequent to completion of the intervention |
| Quality of Life (Positive and Negative Affect Scale) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on health-related quality of life at the conclusion and 9 months subsequent to completion of the intervention |
| Quality of Life (State Trait Anxiety Inventory-S Scale) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on health-related quality of life at the conclusion and 9 months subsequent to completion of the intervention |
| Quality of Life (Visual Analog Pain Scale) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on health-related quality of life at the conclusion and 9 months subsequent to completion of the intervention |
| Quality of Life (SF-12 Health Related Quality of Life Survey) | Months 0, 9, and 18 | To compare the effects of 9-months of strength training to a control group on health-related quality of life at the conclusion and 9 months subsequent to completion of the intervention |
