red muscle


Also found in: Dictionary, Thesaurus, Encyclopedia.

red mus·cle

slow-twitch muscle in which small dark "red" muscle fibers predominate; myoglobin is abundant and great numbers of mitochondria occur, characterized by slow, sustained (tonic) contraction. Contrast with white muscle.

One of the two main types of skeletal muscle, which contains abundant mitochondria and myoglobin. Red muscle fibres contract and fatigue more slowly than white fibres and generate ATP by aerobic catabolism of glucose and fats, utilizing myoglobin-bound O2

Two types of skeletal striated muscles were used; a muscle commonly called red muscle, m.
(1981) suggested that the inner and outer layers are analogous to aerobic red muscle in fish and are used for slow, steady swimming and rhythmic, respiratory contractions, while the central layer is analogous to anaerobic white muscle and is used during burst swimming, escape, and capture events.
Slow twitchers prefer less aggressive movements like marching, which utilizes red muscle fibre.
These novel genes are associated with the pathway of muscle fiber formation (red muscle) and oxidative metabolism of muscle.
Duck breast meat is regarded as red meat, owing to its higher concentration of red muscle fibers.
First, pink muscle has faster kinetics than red muscle. In isometric contractions, the rates of activation and relaxation of pink muscle are about twice those of red muscle.
His experiments show that most of the locomotive power for steady swimming comes from the fish's driveshaft - the area of the red muscle nearest the tail.
Daun and Akesson (2004) noted that duck meat is categorized as oxidative muscle (red muscle) which has more mitochondria and myoglobin than white muscle.
To better understand how mechanical power output is influenced by a muscle's ability to relax, we altered the relaxation rate of isolated red muscle bundles from the scup by using cyclopiazonic acid (CPA) to inhibit their SR [Ca.sup.2+] pumps.
Thigh muscle, which is a red muscle, predominantly consists of type I muscle fibers with relatively large quantities of mitochondria and myoglobin, while breast muscle, which is white muscle, has a high ratio of type IIB muscle fibers and comparatively smaller quantities of mitochondria and myoglobin (Jayasena et al., 2015).
