The effect of short-lasting intensive physical exercise on ATP content in the rat muscles and liver

Using the method of column chromatography the content of adenyl nucleoptides in the muscle and liver homogentates was determined in the rats subjected to short-lasting, intensive physical exercise. Following the exercise a slight increase in AMP and a decrease in ATP levels were found in the liver. In the muscles the levels of AMP and ADP increased while the level of ATP decreased markedly.
