[Changes in the content of iron, copper and manganese in animals during disadaptation caused by heavy loads].

The exchange of microelements in the animal organisms under the influence of overtraining with static loads has been studied. In chronic experiments on 11 male dogs of impure-breed by the method of emission spectral analysis it has been established that the heavy physical loads cause the decrease of iron content in blood and a simultaneous reduction of the iron content and, partially, copper and manganese content in the internal organs of animals. The addition of microelements to the usual food allowance promotes the faster restoring of the violated microelement balance and animals' capacity for work.
