This trial aimed to assess the qualitative traits of five muscles of 14 Nellore bulls with 450 kg ± 30.7 kg BW, feedlot fed for 60 days. After slaughter and carcass chilling, samples of the Biceps femoris (BF), Longissimus (LD), Gluteus medius (GM), Semitendinosus (ST) and Trapezius thoracis (TT) muscles were collected, vacuum-packed and aged at 0 to 2 ºC for 1, 7 and 14 days and subsequently stored at –20ºC for chemical and quality analysis. The pH, shear force, water holding capacity, cooking losses, meat color and ether extract were evaluated in all aging times. Data were analyzed in a split-plot design using the PROC MIXED procedure of SAS. Aging affected quality traits and chemical properties of the meat, improving aspects, such as tenderness (p &lt;...

The purpose of the present study was to examine the relationship between the electromyographic (EMG) activity and heart rate (HR) responses induced by isometric exercise performed by knee extension (KE) and flexion (KF) in men. Fifteen healthy male subjects, 21 ± 1.3 years (mean ± SD), were submitted to KE and KF isometric exercise tests at 100% of maximal voluntary contraction (MVC). The exercises were performed with one leg (right or left) and with two legs simultaneously, for 10 s in the sitting position with the hip and knee flexed at 90o. EMG activity (root mean square values) and HR (beats/min) were recorded simultaneously both at rest and throughout the sustained contraction. The HR responses to isometric exercise in KE and KF were similar when...
