Abstract
The cardiopulmonary capacities of 15 selected 10 yr old ice hockey players were determined during a discontinuous steady-state bicycle ergometer test. During the test, heart rates, minute ventilation and O2 uptake were monitored and the peak values at maximal capacity were recorded. Blood was collected from the median cubital vein after each maximal exercise for lactate analysis. These boys represented a select group of highly successful young hockey players. They had been involved in organized hockey for a mean of 4.4 yr, 2.9 of which had been spent in a competitive league. The team has ranked 3rd in the Ontario [Canada] Championships. The maximal O2 uptake [.ovrhdot.VO2 max] was 56.6 ml/kg .cntdot. min, a value much higher than reported for healthy inactive boys and close to values reported for young athletes in other sports. Mean maximal minute ventilation reached 64.5 1/min (1.84 1/kg .cntdot. min). The tests on these athletes were carried out on 2 separate occasions, 48 h apart. The test-retest correlations for .ovrhdot.VO2 max was high (r = 0.81). Only the reliability of the lactate determinations was low (r = 0.24). None of the differences between the mean values for the measurements made at the 1st and 2nd exercise tests were significant.
