Abstract

Belt squat testing measures maximum upward isometric force from the lower extremities using a ground-tethered belt around the waist. A lack of standardized body positioning during isometric belt squat testing can lead to inconsistent test results. We aimed to evaluate the influence of sagittal knee joint angles on maximum isometric belt squat performance. Thirty-three healthy volunteers (24 female) performed one maximal effort belt squat at five randomly ordered sagittal knee joint angle ranges: (1) 80-100°, (2) 100-120°, (3) 120-140°, (4) 140-160°, and (5) 160-180°. Sagittal knee joint angles between 120-140° and 140-160° led to greater maximum vertical ground reaction forces compared to each other condition (p £ 0.017). Our results provide a starting point to establish best-practices for assessing lower limb strength during maximum isometric belt squat testing.
