Effect of physical training on carnitine concentration in liver, heart and gastrocnemius muscle of rat.
Physical training by compulsed swimming induces in rat heart a significant increase in the concentrations of carnitine and free carnitine but no detectable changes in liver and gastrocnemius muscle are observed. These results are consistent with the increased utilisation of fatty acid and pyruvate in trained animals and with an enhanced demand for carnitine by heart muscle.
