When performing a wall sit or squat (repeated motion with the squat) what major muscle groups are being used? What system do you think are interacting during the process

When performing a wall sit or squat, the muscle groups that are primarily used are the muscles of the thigh, buttocks and lower abdomen, with the muscular, skeletal and joint systems interacting during the process.

Explanation:

Squats are a movement that consists of bending the lower limbs - thighs on hips and legs on thighs - that is repeatedly used as a muscle-strengthening routine.

In squats, the main muscle groups involved are:

Femoral quadriceps, on the front of the thigh. Biceps femoral, semitendinosus and semimembranous, in the posterior aspect of the thigh. Gluteal muscles. Rectus and oblique abdominal muscles.

Other thigh muscles, such as the adductors and pectineo, contribute to stabilization during movement.

The systems involved in squats are those related to the muscles, already mentioned, bones - hip, tibia femur, and fibula - and the corresponding joints:

Coxofemoral joint, between hip and femur. Knee joint, between femur and tibia-fibula.

The cooperation of these systems allows an adequate movement known as squatting or wall sitting.
