So while the quadriceps muscles are contracting concentrically during the upward phase of the squat, and eccentrically during the downward phase, many of the deeper muscles of the hip contract isometrically to stabilise the hip joint during the movement.
What is the concentric phase of a squat?
What is A Concentric Squat? A concentric squat is when the concentric (ascending) phase of the squat is prioritized, typically by slowing down the speed and/or starting the squat from a deadstop in the bottom position. Concentric squats involve a phase where the muscles are shortening.
What muscles are being used during the negative phase of a squat?
Muscles Involved in Squatting
Active muscles include the quadriceps, hamstrings, gluteus maximus, gastrocnemius and soleus muscles of the calf, posterior tibialis of the lower leg and foot, and numerous smaller muscles in the foot and ankle.
Do squats make your thighs bigger or smaller?
Although lunges and squats tone and define your thigh muscles, they won’t make them smaller. In fact, you might notice your thighs getting bigger from exercise.
Do squats make your butt bigger?
Squatting has the ability to make your butt bigger or smaller, depending on how you’re squatting. More often than not, squatting will really just shape up your glutes, making them firmer instead of bigger or smaller. If you are losing body fat on top of performing squats, then your butt will likely shrink.
What two body movements should happen during a squat?
As the body descends, the hips and knees undergo flexion, the ankle extends (dorsiflexes) and muscles around the joint contract eccentrically, reaching maximal contraction at the bottom of the movement while slowing and reversing descent. The muscles around the hips provide the power out of the bottom.
What is the prime mover in a squat?
As such both front squats and back squats work the same muscle groups; prime movers include gluteals and quadriceps; synergists include the hamstrings; and stabilizers include the deep abdominal muscles (transverse abdominis).
Why is the down phase of a squat eccentric?
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.
What are the phases of a squat?
Muscles Used in the Different Phases of the Squat
- Lowering Phase: Mechanics. During the lowering phase of the squat, the body moves from a standing position into a squat — as if you are going to sit on a chair.

What is the prime mover in a deadlift?
Your quadriceps, hamstrings and glutes are the prime movers for the deadlift. In the initial pull, where your hips are maximally flexed and your knees are bent between 85-45 degrees, your hamstrings stabilize your shin while your quads extend your knees.
What is the synergist muscle in a pull up?
According to Frederic Delavier, author of “Strength Training Anatomy,” several synergistic muscles in the arm and back are used to carry out a pull-up, though only the latissimus dorsi and the teres major are the primary movers.
