Brief summary
Does a rotary based triplanar exercise intervention that utilizes the trunk as a proximal lever, strengthen the hip and alter dynamic LE alignment in running females?
Detailed description
Current hip-focused programs fail to alter hip adduction angles in females while performing higher speed and more complex maneuvers such as running. (Willy, et al., 2011) - 10 female runners, underwent 6 wk. hip focused intervention, change in SLS but NO change in hip adduction angle while running. A different intervention strategy that includes utilizing the trunk as the proximal lever to strengthen the hip, could potentially alter biomechanical outcomes such as hip adduction angles in female runners. This study will apply a new intervention model and then measure running, single leg squat and hip strength to determine if a newly informed intervention can alter LE kinematics in females while running and make improvements in hip strength following the intervention Inclusion Criteria * 18 years old or greater * Female Exclusion Criteria * Injury of the lumbar spine, hips, knees or foot/ankle in the last 6mos that required medical attention * any surgery of the lower back or the pelvis or lower extremities any time in the subjects life
Interventions
OTHERTriplanar Rotary Resistance
Trunk group will strengthen the hip using the trunk as a lever to access the hip. The hip group will use femur as the lever to strengthen the hip.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Hip Strength after a 12 week hip focused intervention | Baseline measures at initial data collection; repeat post intervention measures at 6wks | Isometric hand held dynamometer |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Biomechanical assessment of single leg squat | Baseline measures at initial data collection; repeat post intervention measures at 6wks | Subject squats on single leg and qualitative scoring is administered to determine the subjective amount of contralateral pelvic drop and femoral adduction to be described as dynamic knee valgus. The qualitative values will be binary in nature, whereas DKV is present or not. |
| Biomechanical Running Assessment | Baseline measures at initial data collection; repeat post intervention measures at 6wks | 2/3D analysis of running gait following intervention; Utilizing both 3D/2D methods the measure of contralateral pelvic drop and the bisection of the patella will determine the amount of femoral adduction noted during running. The change in the femoral adduction angle after a 6 week intervention is the specific outcome measure to be obtained. |
