AB  - The purpose of this study is to measure the comparative analysis pennation angle of the vastus
intermedius and vastus lateralis in the squat position of the knee angle. Knee angle was set as 0°, 60°, 75° and
90° the vastus intermedius and vastus lateralis of pennation angle of the knee angle was measured using
ultrasonography. All measurements of the experiments were performed by one-way ANOVA. According to a
study 0°, 60°, 75° and 90° that was pennation angle is greatly increased in the knee angle of 75°, all the
statistical value has differences but 60° and 90° was statically significant than other values. The study found
out the significant difference between the pennation angle of men and women. In conclusion, the result of
experiment shows that the quadriceps muscle was most stimulated when we did a squat exercise while flexion
our knee at an angle of 75°. Clinically, it is considered that the interaction between knee angle and quadriceps
muscle will help to prevent injuries related to quadriceps muscle such as patellofemoral pain syndrome.
