The study aims to assess the myotonometer parameters of major pectoralis, biceps brachialis, femoral and anterior tibialis in patients with Parkinson’s disease before after medical treatment using comparisons healthy controls. A total 49 (69.76 ± 6.39 years) 42 controls (60.48 7.62 were tested MyotonPRO one hour drug administration. Five recorded (frequency [Hz], stiffness [N/m], decrement, rel...

Pectoralis major muscle morphology was studied in both sexes of a turkey line (E) selected long-term for increased egg production and its randombred control (RBC1) from 25 d of incubation through 20 wk posthatch. Pectoralis major muscle samples from 10 individuals from each line-sex-age subgroup were obtained in a manner to prevent contraction. The muscle samples were dehydrated, cleared, embed...

The effect of the timing of posthatch feed restriction on adipose deposition and adipogenic gene expression in the broiler pectoralis major muscle was studied by applying a 20% feed restriction either the first or second week after hatch. Broiler chicks at hatch were divided into a full-fed (control) group and a 20% feed restriction group. The expression of adipogenic genes, peroxisome prolifer...

Breast support has previously been shown to influence surface EMG of the pectoralis major during running. Reductions in muscle activity have previously been associated with a reduction in energy cost, which may be advantageous for female runners. Ten female participants performed two self-paced (average pace 9 km h(-1)) 5 km treadmill runs under two breast support conditions (low and high); an ...

The myoelectric signal of the sternoclavicular and clavicular portions of the pectoralis major, the biceps brachii, and the lateral head of triceps brachii of 12 healthy men was collected during an isometric hold of 5 different bench press exercises. Grip width (narrow, mid, and wide) and the level of supination/pronation was varied to determine how these factors influence myoelectric amplitude...

AIM The aim of this study was to evaluate almost 20 years of using the pectoralis major flap in head and neck reconstruction at the Department of Maxillofacial Surgery, Zagreb. PATIENTS In the period from 1981 to 1999, a total of 506 pectoralis major flaps were used for head and neck reconstruction in 500 patients. In all cases the flap was used after surgical resection of an advanced maligna...
