Which angle builds stronger knees? small study tests two positions
NCT ID NCT07456254
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether changing the angle of a leg exercise machine (N-K Table) from 0° to 50° helps people with knee osteoarthritis activate their thigh muscles more. Forty-three women aged 50-65 with knee osteoarthritis did isotonic knee extensions at both angles. Muscle activity was measured using surface electromyography. The goal is to find the best angle for strengthening exercises.
