Final answer:
When Ruby performs an overhead squat assessment, a movement compensation that indicates the need for a static standing TFL stretch is knee valgus, where the knees move inward. A tight TFL can contribute to knee valgus, and a stretch targeting this muscle can help improve squat form and reduce injury risk.
Step-by-step explanation:
Ruby performs an overhead squat assessment to determine if there are any movement compensations that need to be addressed in her workout routine. One indication that a static standing TFL (Tensor Fasciae Latae) stretch is needed is if, during the squat, there is an observable knee valgus, where the knees move inward towards the midline of the body. Tightness in the TFL can contribute to this movement pattern because this muscle, along with the gluteus maximus, forms the iliotibial band which, when tight, can pull the knees inwards.
To perform a static standing TFL stretch effectively, she should stand and cross one leg behind the other, lean her hips to the side opposite of the crossed leg, and raise the arm on the same side of the crossed leg over her head to enhance the stretch on the lateral side of the thigh. This stretch targets the TFL specifically and can help in reducing the tightness that leads to knee valgus during an overhead squat assessment. Consistently including this stretch in her routine may improve squat form and reduce the risk of related injuries.
