Chronic exercise training alters kinetic properties of rat skeletal muscle and myocardial lactate dehydrogenase. 1986

L L Ji, and F W Stratman, and H A Lardy

10 weeks of treadmill running dramatically altered the kinetic properties of lactate dehydrogenase (EC 1.1.1.27) in skeletal muscle and myocardium in the rat. These changes, including Vmax, Km and optimal concentrations for pyruvate and lactate, indicate that exercise training induces the formation of H-isozyme in skeletal muscle and M-isozyme in the heart and represent metabolic adaptations of these tissues to chronic aerobic exercise.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D007770	L-Lactate Dehydrogenase	A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist.	Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase
