The experiment involved 36 rowers with 2.9 years of experience and 32 non-sportists of usual and physical fitness and activity. On two occasions and at random, the testing was carried out on the rowing and bicycle ergometer. The test of maximum load of type "all out" was administered for 6 minutes. The cardiorespiratory parameters were registered continuously at the end of warming up, during load and during first 6 minutes of recovery. The maximum oxygen consumption (VO2max) was for the rowers 4.83 1/min on the rowing and 5.00 1/min on the bicycle ergometer.
For non-sportists, these values were 3.62 1/min on the rowing and 3.67 1/min on bicycle ergometer. The registered differences for both groups were not significant statistically. All parameters that directly or indirectly indicate physical fitness and their changes are a direct consequence of adaptational processes on physical activity (VO2max, ventilation, O2 pulse, load, etc) and are smaller by about 25 to 35% for non-sportists.
In the case of the rowers, there was not a significant difference in the results obtained on the two ergometers, so these results can both be used to determine physical fitness.
The non-sportists, however, do not show a significant differences in oxygen consumption registered on the rowing and bicycle ergometers, but the load on the bicycle ergometer was about 16% greater which is statistically significant at the significance level p<0.001, The explanation for this lies in the fact that non-sportists do not have a formed dynamic stereotype of rowing motions. This is why the non-sportists for every kJ work on the rowing ergometer "pay" with 6 ml of oxygen more than the rowers which is the price for redundant and inefficient motions.
