The short face aid in the training of the shoulder (surveys to the front), rotation for inside, horizontal flexo and aduo. (Similarly see: Dean Ornish M.D). The short face rare is injured. The two faces of the biceps if join to form the common tendo that crosses the together one of the elbow and if it binds in the bone radio of antebrao. The brachialis are under the inferior part of the biceps, originating in the portion lowest of humerus and if it binds in the superior area of ulna of antebrao. Its only function is the flexo of the elbow, then it works in all the biceps exercises, exactly that they use it more to some than the others. Its ligament to ulna makes the brachialis equally effective, is the hands proswims, supinadas or in a neutral position. Had to this, and by its force to rival with the one of brachium of the same biceps with its relatively lesser mass (it has to balance the forces exerted in the radio of antebrao for brachium of the biceps), the brachialis are considered the true engine of the flexores of the elbow. The brachioradialis accumulate of stocks all the extension of antebrao, of humerus soon above of the elbow until a point in the radio soon above of the pulse.
The brachioradialis act as a long handspike and this allows that it initiates the thread movement of a form that nor the biceps nor the brachialis could. Adding the flexo of the elbow, the brachioradialis estabeliza the radio in this together one and acts as supinador when the hand is anything and as pronador when it is supinada. The brachioradialis contract more strong and function more effectively when the pulses are in a neutral position. To hold neutralmente also is the form more effective to hold for involving brachii of the biceps since, in this position, the biceps have a line push straight line. Supinados or supinantes movements, however, supply the biggest development since they work the biceps in both the actions of flexo and supinao.
