    Abstract:
    In conditions of enhanced motivation trained subjects performed a greater work and untrained ones--a lesser work than under ordinary motivation. The most stable parameters in regard to working to capacity were as follows: heart rate, minute respiratory volume, amount of oxygen consumption, amount of exhaled CO2, energy expenditure, and oxygen pulse. The data obtained show that untrained subjects under ordinary and, particularly, enhanced motivation for working to capacity are able to mobilize a lesser amount of the organism's physiological reserves than trained people.
