Abstract

The purpose of this study was to examine the kinematics of lower extremity and spine in response to different mass loads in front squat exercise. Three experienced male varsity athletes were recruited to participate in this study, and each participant performed five trials of front squat exercise at three different loads (65%, 75%, and 85% of 1 repetition maximum). A standard two-dimensional kinematic analysis was conducted and the result showed that the participants had no significant difference on different loads in both lower extremity and spine. However, the knee joint demonstrated a strong sensitivity in response to load mass, so a strength training program may be prescribed focusing on the knee joint stability. Future research studies are warranted to examine the kinematic differences between a knee-braced front squat and a plain front squat.
