Most people don’t squat correctly. In theory courses on strength and conditioning in college exercise science programs, about 90 percent of students perform the squat incorrectly at the beginning of the semester. Most of these students played sports in high school. A panel of experts associated with the National Strength and Conditioning Association developed an assessment tool to help athletes learn proper squatting techniques. The checklist includes assessment of proper positions of the head, thorax, trunk, hips, knees, tibial angle and feet. It also assesses movement mechanics during descent and ascent and squat depth. This is a valuable tool that will help people learn to safely squat correctly. Squatting is a vital exercise, but it can cause great harm if done incorrectly.
