Muscle Activation in Hip vs Knee: A Student Study

Eleven university students took on 13 hip-focused exercises, the kind you'd do if you had knee issues. Researchers tracked muscle activity using a special tool called surface electromyography (sEMG). They looked at key muscles like tensor fasciae latae (TFL), gluteus medius (GMed), gluteus maximus (GMax), and some from the knees like adductor longus (AL), vastus medialis (VM), and vastus lateralis (VL). The students did exercises like the side-lying clam-shell, hip hike, forward lunge, squat, and single-leg squat with a resistance band. The goal? To see which exercises activated hip muscles more than knee muscles.

Turns out, the side-lying clam-shell was a champ at making the gluteus maximus (GMax) work harder than the adductor longus (AL). The hip hike exercise was great for the gluteus medius (GMed) compared to the adductor longus (AL). As for the knee muscles, the VL/VM ratio varied but stayed close to 1, showing balanced activation. So, if you're looking to target hip muscles more, maybe try the side-lying clam-shell or hip hike. But remember, every body is different, and what works for one might not work for another.
