For proper comparisons, the RMS value (Root Mean Square) obtained for each muscle (pectoralis major, anterior deltoid
, biceps brachii, and triceps brachii) was normalized to the peak values obtained relative to all exercise modes.
Activation of the anterior deltoid
did not differ significantly between smith machine shoulder press (70 [+ or -] 12.
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.
40), but anterior deltoid
EMG increased more when carrying the load at the sides (p = .
Works: Triceps (back of the upper arm), anterior deltoid
, chest and upper back.
Daily tasks like wheelchair propulsion, transfers, and weight shifts involve relatively high force pressing actions that stress the anterior deltoid
, triceps, and pectoral muscles.
The anterior deltoid
helps to raise the arm forward and is used in the initial phase of lifting the bow arm.
Comparison of EMG of the brachial triceps and anterior deltoid
in the shoulder development exercises and triceps bench press
14) reported similar electromyographic (EMG) activity in the anterior deltoid
and pectoralis major during 3 repetitions at 80% of 1 maximum repetition (RM) on a bench and Swiss ball.
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.
It was hypothesized that the highest core and upper extremities muscle activation would be induced by the suspension system with the pulley, except for the pectoralis major and anterior deltoid
, which were expected to show similar muscle activation in stable and unstable conditions.
The muscles selected were: Erector spinal neck, trapezius, supraspinatus, pectoralis, anterior deltoid
, middle deltoid, infraspinatus and latissimus dorsi.
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)
