[Ergometric methods of examination]

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.
