The purpose of the study is research of the energy balance peculiarities in different kinds of muscular tissue of descendants of the irradiated animals after an exercise load. It is determined that after increasing a radiation dose of animals their descendants display after exercise load decreasing of the content of main macroerg of the muscular tissue — ATP against the abrupt rising of AMP with regard to intact infant rats. At the same time different directions changes of ADP content take place, which are characterised by increasing of this compound in muscular tissue of the infant rats born from irradiated animals in the dose of 0.5 Gy and by fall at the infant rats born from irradiated in the dose of 1.0 and 3.0 Gy.
