الملخص EN

This study aims to determine the ideal angle of the knee during the squat exercise In two styles, restricted and unrestricted , in restricted style it restricts the knee down to be nearer to the idea angle 90º so that backbones angle is 180º .

The researcher used the descriptive method, as it is suitable to her study; the study sample chosen by random method (2) players in fitness center (Tyrpo Jam), there is a significant difference in amount of angle of the knee joint during the exercise between the two styles.

The restricted is very near to the ideal angle of backbone is 180º so it decreases the average of pressure because the backbone in ideal angle , there is difference in the knee joint angle for the use of restricted this decrease the knee and backbone pains.
