Heartrate Response to a Single Submaximal Workload (Astrand's Test) as an Estimate of Maximal Oxygen Uptake in British Servicemen
Abstract
Accuracy of the 6 min cycle ergometer predictive test, as practised at APRE, was compared with actual maximal oxygen uptake by uphill treadmill running using 165 servicemen subjects. Standard error of estimate of the regression between the 2 sets of results was 4.8 ml(kg min), about 10% of the mean. Similar accuracy was found in comparing the submaximal test with maximal ergometer cycling. Accuracy was not improved by using submaximal oxygen uptake rather than workload data in reading Astrand's Nomogram. The submaximal predictive test was however less accurate for a group of competition skiers. Repeatability of the submaximal test was considered adequate since it gave smaller standard deviation of differences than did the comparison of submaximal and maximal tests. Diurnal effects were shown to be of little practical importance, and 2 computer programs which avoid manual use of the nomogram were shown to introduce negligible error. The test, with the derived regression equation, is confirmed as being of sufficient accuracy for use in population studies of British servicemen, but is not recommended for examination of individual work capacity, or for tests on very fit groups such as competition skiers.
