Fast-twitch muscles (white fibers) have a greater ATPase activity and this should yield tender meat due to the lower activity of calpastatin (Geesink, Kuchay, Chishti & Koohmaraie, 2006), because of the negative correlation between the calpastatin activity and the myofibrillar ATPase activity (Geesink, Taylor, Bekhit & Bickerstaffe, 2001).
