The "lat" sometimes added before "pull-down" commonly refers to the latissimus dorsi used in the movement. Most exercises describe the muscle that is involved and the direction of the exercise e.g. biceps curl, triceps extension, leg press, hamstring curl, abdominal curl and so on.
Build big, strong latissimus dorsi muscles takes more than just pull ups. Add these lat exercises and workouts to your routine to add major size and strength. The Best Lat Exercises to Build a ...
The latissimus dorsi is a potential source of muscle for breast reconstruction surgery after mastectomy (e.g., Mannu flap) [12] or to correct pectoral hypoplastic defects such as Poland's syndrome. [13] [14] An absent or hypoplastic latissimus dorsi can be one of the associated symptoms of Poland's syndrome. [15] [16]
[1] [3] [4] The trapezius, infraspinatus, and brachialis muscles are most active at the beginning of the pull-up; the latissimus dorsi, teres major, and biceps brachii reach peak activity during the middle of the movement, and the triceps brachii and subscapularis experienced maximum activity at the top of the movement. [5]
The concentric portion is usually the part of the exercise that you think of as “the lift”—it’s the pressing portion of a bench press, standing up out of a squat, pulling the bar from the ...
The origin of a muscle is the bone, typically proximal, which has greater mass and is more stable during a contraction than a muscle's insertion. [14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso.
In concentric contraction, muscle tension is sufficient to overcome the load, and the muscle shortens as it contracts. [8] This occurs when the force generated by the muscle exceeds the load opposing its contraction. During a concentric contraction, a muscle is stimulated to contract according to the sliding filament theory. This occurs ...
This movement has also been described as negative training. This "negative" movement is necessary to reverse the muscle from its initial trajectory. [1]When the load exceeds the force that can be developed by the muscle at a constant length, as in an eccentric muscle action, the exercise is referred to as involving negative work, because the muscle is absorbing energy.
