Anatomy of the Sumo Deadlift

This is the third post in a series looking at the the muscles used in each of the lifts which form part of a powerlifting competition. There are two styles of Deadlift which are legal lifts in a Powerlifting competition. The first, is the conventional Deadlift and the second which I will discuss below is the Sumo style Deadlift.

Classification

Sumo Deadlift is classified as

Basic: A principal exercise that can place greater absolute intensity on muscles exercised relative to auxiliary exercises.

Compound: An exercise that involves two or more joint movements.

Pull: Movement toward centre of body during the concentric contraction of the target muscle.

Muscles Used

Target Muscle: The primary muscle intended for exercise.

Gluteus Maximus

Synergistic Muscles: A muscle that assists another muscle to accomplish a movement.

Quadriceps
Adductor Magnus
Soleus

Dynamic Stabiliser Muscles: A bi-articulate muscle that simultaneously moves through the two joints with little change in length, in effect shortening through the target joint and lengthening through the adjacent joint.

Hamstrings
Gastrocnemius

Stabiliser Muscles: A muscle that contracts with no significant movement to maintain a posture or fixate a joint.

Erector Spinae
Trapezius, Middle
Trapezius, Upper
Levator Scapulae
Rhomboids
Latissmus Dorsi

Antagonist Stabiliser Muscles: A muscle that contracts to maintain the tension potential of a bi-articulate muscle at the adjacent joint. The Antagonist Stabilizer may assist in joint stabilization by countering the rotator force of an agonist.

Rectus Abdominis
Obliques
