A concentric contraction is one in which the muscle length decreases to perform a movement. In a squat, this would be the lifting phase of the squat as you stand back up.

What is the isometric phase of a squat?

Which muscles are used concentrically in the up phase of a squat?

In the up phase of a squat the hip joint is extended by the concentric contraction of the gluteus maximus, semimembranosus, semitendinosus and the biceps femoris. The knee joint is extended by the concentric contraction of the rectus femoris, vastus medialis, vastus intermedius and the vastus lateralis.

What is the isometric phase?

Isometric actions are ones in which the muscle attachments closest and furthest from the center of the body (proximal and distal) remain at a constant length. You reach the isometric phase when the force you’re exerting equals the force of the load.

What type of contraction is a squat?

An eccentric contraction refers to any contraction where the muscle lengthens under load or tension. So in the squat exercise, the quadriceps muscles will contract eccentrically (lengthen) in the downward phase of the movement (the opposite direction of the arrow), as can be seen in the adjacent picture.

Is a squat isometric or isotonic?

Isometric exercises, like planks, don’t require you to move or bend any joints. Isotonic exercises, like squats, involve straining the muscles while moving the joints and applying a constant amount of weight. Isokinetic exercises are performed at a consistent speed, which can be increased as you progress.
