EMG] were reported at the trailing UL than at the leading one for the anterior deltoid
, serratus anterior, and lower trapezius at specific ranges of humeral elevation angles (second rotation), calculated within the plane of elevation (first rotation) .
The chest and/or anterior deltoid
are thus used to exercise the pre-fatigued triceps.
max]) muscular demands have been reported at the serratus anterior, latissimus dorsi, supraspinatus, infraspinatus, pectoralis major, anterior deltoid
, and long head of the biceps .
The anterior motor branch courses around the neck of the humerus and passes medially on the anterior surface of the surgical neck to supply the middle and anterior deltoid
The anterior deltoid
and posterior trapezius flaps were then re-approximated over the superior aspect of the clavicle followed by closure of the split in the anterior deltoid
Abbreviations: AD = anterior deltoid
, BB = biceps brachii, EMG = electromyography, MD = middle deltoid, ME = mechanical effectiveness, MVC = maximum voluntary isometric contraction, PC = principal component, PCA = principal component analysis, PD = posterior deltoid, PM = pectoralis major, SCI = spinal cord injury, sEMG = surface electromyography, TB = triceps brachii, UT = upper trapezius.
The elbow of one arm was flexed until the dumbbell reached the height of the anterior deltoid
at the end of the upward phase, and was then returned to the original position during downward phase.
Surface electrodes were used for upper trapezius, anterior deltoid
, middle deltoid, posterior deltoid and pectoralis major.
Muscular twitches involving the anterior deltoid
at a depth of 6 to 8 cm indicate the axillary nerve has been located.
Works: Triceps (back of the upper arm), anterior deltoid
, chest and upper back.
The anterior deltoid
helps to raise the arm forward and is used in the initial phase of lifting the bow arm.
The computer model included seven muscles that were simulated as three lines from origin to insertion: anterior deltoid
, middle deltoid, posterior deltoid, subscapularis, infraspinatus, teres major, and teres minor.
Therefore, the purpose of this study was to examine muscle activation of the pectoralis major (PM), triceps brachii (TB), biceps brachii (BB), anterior deltoid
(AD), trapezius (TR), and rectus abdominus (RA) during the chest shake (CS), biceps shake (BS), and triceps shake (TS) using the SW and DB of the same absolute weight.
EMG signals were recorded from seven muscles for each subject: brachialis, biceps, medial head of triceps, posterior deltoid, anterior deltoid
, middle deltoid, and clavicular pectoralis major.
Works: Triceps (back of upper arm), pectoralis group (chest area) and anterior deltoid
(front area of shoulder)
