what is the Kelly Starrett Hip extension test

The Kelly Starrett Hip Extension Test involves a unique method to assess hip extension competency. The test includes positioning the front foot onto a 12 to 18-inch box, elevating the leg into what is called a "hip lock." This posture emphasizes hip extension, as the elevated position rotates the pelvis and challenges the extension mechanics of the rear leg. This test simulates the mid-stride position seen in sprints, where the front knee is high and the rear leg is extended behind 1.

The purpose of this setup is to identify any deficits in hip extension. By practicing this test, individuals can improve their hip extension by engaging in various exercises like split squats and lunges. The test is designed not only to highlight deficits but also to serve as a static position where you can hold, breathe, and perform contract-relax techniques to improve hip function. Adjustments and activities in one's movement practices are crucial to enhancing hip extension effectively 1.
