The effects of training on the monocarboxylate transporter (mct1) in skeletal muscles and the heart

Themonocarboxylate transporter l (MCT1) protein is found in both red and white skeletal muscles as well as in the heart. Concentrations of MCT1 are however graded among these tissues as follows: heart > red muscle > white muscle. Since training decreases circulating lactate concentrations and increases lactate transport in isolated vesicles we examined the effects of treadmill training on MCT1 in metabolically heterogeneous skeletal muscles …
