ABSTRACT:
The purpose of this study was to develop a submaximal test, on the Concept II rowing ergometer, to estimate the maximum oxygen uptake (VO2max) of male rowers and non-rowers. Eleven rowers and 14 non-rowers completed a submaximal and a maximal rowing test. The submaximal test consisted of exercising for 6 min at five different incremental speeds with at least 6 min recovery between each speed. Speed, heart rate and oxygen uptake were monitored during the last minute of each increment. In the maximal test, the subjects were asked to row for 6 min at a speed calculated to elicit 105 percent of their predicted maximum heart rate (HRmax). The HRmax was predicted from 220 beats min-1-age. Actual HRmax was recorded and the highest value of oxygen uptake measured was regarded as the subject's VO2max. An analysis of covariance revealed that the data collected for rowers and non-rowers had to be considered separately. The greatest differences were seen for the submaximal speed-VO2 relationship, which showed that the rowers were more efficient on the ergometer than the non-rowers. Measured HRmax was found to average 9 beats min-1 below the predicted HRmax. The measured VO2max values for the whole group averaged 4.16 plus/minus 0.64 1 min-1(mean plus/minus S.D.). A nomogram was developed to predict VO2max. At an exercise intensity of 80-90 percent HRmax, the average estimated VO2max using predicted HRmax calculated from 220 beats min-1age, was 4.34 plus/minus 0.7 1min-1. Using measured values of HRmax, the average estimated VO2max was found to be 4.06 plus/minus 0.6 1min-1, which reduced the mean error of the estimate from 4.3 to 2.4 percent. This study shows that rowing VO2max can be estimated from a submaximal exercise test, with an mean error of the estimate of less than 5 percent provided that the exercise intensity of the test is approximately 80-90 peceent HRmax.
