Influence of cyclic and sustained squatting on knee power and hemodynamics

Occupations with regular exposure to squatting have a greater risk of developing knee osteoarthritis. To determine the effects of squatting exposures on subsequent knee power generation and concurrent muscle oxygenation, participants completed cyclic and sustained squatting exposures, with countermovement jumps before and after. Even acute exposures to high knee flexion postures were detrimental to the development of knee power in subsequent tasks. Males also exhibited greater reductions in knee power and tissue saturation index. Duration of the posture may be more detrimental than frequency.
