Purpose: This study examined the various patterns of standing to squatting activities, and reports the testing standard and phases for examining the standing to squatting position.
Methods: One thousand, normal college students (500 males, 500 females) volunteered for this study. The patterns are performed by naked eye analysis with two video cameras.
Results: The patterns from the standing to squatting position are as follows 1. parallel with the heel on the pattern: 2. parallel with the heel off the pattern: 3. closed with the heel on the pattern: 4. closed with the heel on the pattern: 5. open with the heel on the patternand 6. open with the heel on the pattern.
Conclusion: The phases of the standing to squatting position are as follows: phase I from standing to the anterior parts of the knees reaching the anterior limit of the BOS, phase II from phase I until the height of the hip and knee joints are the same, phase III from phase II until there was no full squatting and the heels broke contact with the floor and phase IV from phase III full squatting on the heels in contact with the floor.
