[Ergometric methods of examination]. / Ergometricheskie metody obsledovaniia.

Human fitness for work is dependent upon potential of energy systems (oxidation, phosphagenic, and lactic acid) and economy of motions. Metrologically correct techniques of measuring the energy of the oxidation system and the capacity of the phosphagenic and lactic acid systems are developed. The economy of motions is derived as the ratio of the carried out mechanical work to the total energy consumption or as the ratio of the total energy consumption to the distance covered. Important ergometric features are also the optimum power (most economical) of the pedal operation on a bicycle ergometer and the optimum velocity of walking and running.

[Effect of single and systematically repeated physical exercise on the threshold of anaerobic metabolism]. / Vliianie odnokratnykh i sistematicheski povtoriaiushchikhsia fizicheskikh nagruzok na porog anaérobnogo obmena.

The anerobic threshold (AT) has been defined in 37 healthy young subjects and adults after single and repeated exercises close to the threshold one as regards the intensity. Single exercise lasted 1.5--2 h, whereas repeated ones 7 days to 5 months. The AT has been found to drop significantly at single exercises and to increase at systematic exercises lasting 30 days and more.

[Clinical importance of evaluation of the effect of bicycle exercises on cardiodynamics of patients with ischemic heart disease]. / Klinicheskoe znachenie otsenki vliianiia na kardiodinamiku veloergometricheskikh nagruzok v protsesse ikh vypolneniia bol'nymi ishemicheskoi bolezn'iu serdtsa.

An analysis of the results of polycardiographic examinations conducted during muscle work done by patients with ischaemic heart disease extends our knowledge of the functional state of the myocardium and is of certain prognostic importance; besides, such an analysis permits to make the prognosis of the effect of cardiac glycosides on the heart rhythm.
