Importance of Hip Extension During Running
During the toe-off phase of running, at least 10-15 degrees of hip extension range is crucial to set up for efficient propulsion. This is also known as triple extension when the trail leg is in full hip, knee, and ankle extension.
Issues That Can Occur When There Is a Lack of Hip Extension
When a runner lacks proper hip extension mobility, some common compensations that can occur include lumbar spine hyperextension, shortened running stride, and increased loading at the ankle joint. Inefficient running form can eventually lead to a repetitive stress injury.
