Impact of a Long Run on Injury-Related Biomechanics with Relation to Weekly Mileage in Trained Male Runners.

abstract：:Motion of the femur and pelvis during hip flexion has been examined previously, but principally in the sagittal plane and during nonfunctional activities. In this study we examined femoral elevation in the sagittal plane and pelvic rotation in the sagittal and frontal planes while subjects flexed their hips to ascend ...
