Abstract
Intraindividual variation in oxygen debt was determined following maximumeffort work and a near-maximum-effort work at a given rate by means of the Monark's bicycle ergometer for sixty seconds. Both experiments were carried out four times, respectively. At the same time the measurement of work done and rectal temperature at rest were taken. Every experiment was carried out once a day at the same hour (9 : 00) on the moring of Monday.
Intraindividual variation in oxygen debt, work done and rectal temperature was expressed in terms of a coefficient of variation (C. V.: %) . The subjects were four healthy male students, aged 18-21.
The results obtained are as follows
1) The C. V. value of intraindividual variation in oxygen debt following maximum-effort work was from 4.7% to 15.3% and its mean value was 9.1%.
2) The C. V, value of intraindividual variation of the work done following maximum-effort work was from 0.7% to 2.5% and its mean value was 1.4%.
3) The C. V. value of intraindividual variation in oxygen debt following a nearmaximum-effort work at a given rate was from 7.0% to 12.8% and its mean value was 9.5%.
4) The mean value of the work done following a near-maximum-effort work at a given rate was 85.8% in contradistinction to maximum effort work. The mean value of C.V, of work done was 1.1%.
