Quick Tip Tuesday!
This is an example of collapsing mechanics while running: loss of knee window (green arrow), and pelvic drop (red line). Pelvic drop refers to the hip on one side dipping down too much, and a loss of knee window means your knees are coming too close together or even touching.
🦴 Collapsing mechanics can reduce the capacity of bone to absorb force effectively. This is especially detrimental when running downhill (due to the higher forces on the body), and can cause micro stress to the bone.
🦴 This Quick Tip video demonstrates a motor learning drill to improve a hip drop pattern.
If you notice your knees touching each other while running, I would recommend a running gait analysis to improve your individual running mechanics, strength, and mobility to reduce likelihood of injuries.
