Further, Cochrane (2016a) reported non-significant but moderate-to-large-sized enhancements in peak and mean force during concentric biceps curls after 10 min of local vibration of the biceps brachii
muscle (frequency range: 0-170 Hz) compared to a control condition (i.e., no vibration) in healthy trained males.
Biomechanical evaluation of 4 techniques of distal biceps brachii
DM, deltoid muscle; PM, pectoralis major msucle; BBM, biceps brachii
muscle; MN, median nerve.
The biceps brachii
is a two-headed muscle located in the anterior compartment of the arm.
The Biceps Brachii
Part 1 Cohorts (150 mg and 200 mg pooled) generated a mean total muscle volume increase of 13.2%, and produced a mean decrease or improvement in muscle fat fraction of 0.6%.
Different authors have reported the incidence of the additional heads of the biceps brachii
to be between 0.18%21.5% in different population.
The biceps brachii
tendon functions in flexion and supination of the forearm.
The same procedure was employed for the biceps brachii
(BB) and rectus femoris (RF) muscles [13-15].
The strength at shoulder and elbow joint and electromyographic (EMG) signals from pectoralis major (PM), anterior, intermediate, and posterior deltoid (AD, MD, and PD), biceps brachii
(BB), triceps brachii (TB), and brachioraialis (BR) were recorded during each task (Figure 3).
Manual muscle testing (MMT) at the initial examination revealed the following muscle strengths on the left side: deltoid, 0; biceps brachii
, 0; triceps brachii, 2; wrist flexor muscles, 3; wrist extensor muscles, 3; lumbrical muscles of the hand, 4; and interosseous muscle, 4.
LLLT was applied at four points to the dominant upper limb of the subjects on the belly of the biceps brachii
The scope of the study was limited to one muscle, namely the biceps brachii
of the dominant arm, as it is involved in upper limb activities and, being a superficial muscle, is easily accessible for surface EMG measurements (Maton, 1981).
The intersection point of the biceps brachii
muscle with the lower border of the pectoralis major muscle is defined as the proximal level (P).
Second, we studied responses of orbicularis oculi (O.oc), masseter, sternocleidomastoid (SCM), biceps brachii
, abductor pollicis brevis (APB), and tibialis anterior muscles after supraorbital electrical stimuli, auditory stimuli (auditory startle reflex, ASR), and electrical stimuli of the median nerve at the wrist (startle reflex to somatosensory inputs, SSS).
The main function of the biceps brachii
muscle and its proximal tendons in the shoulder is stabilization, assistance in arm abduction, and flexion and internal rotation.
