Abstract
Astrand cycle ergometry test is probably the most famous and most frequently used sub maximal test aimed at evaluation of the aerobic capacity. In this research the accuracy of test was evaluated based on results comparison with the results obtained during maximal ergometry test, the test which is considered to be an objective indicator of functional status of the individual. The sample consisted of 46 rowers and 22 runners. All the examinees are males in their middle age (35-65 yrs), who are at least twice per week active in rowing or running recreational training sessions. The maximal ergometry test was conducted using the rowing ergometer for the sample of rowers, and treadmill for the sample of runners. Basic statistical parameters were calculated followed by Pearson correlation coefficient. Simple regression analysis was performed and Student T-test and Fisher F-test were used to verify the obtained results. The results pointed out statistically significant, but low to moderate relationship between Astrand test results and maximal ergometry results (r=0.68 for rowers and r=0.56 for runners). Simple regression analysis pointed out statistically significant prediction of true VO2max based on the Astrand test results, but the shared variance turned out to be relatively low (R2=0.46 for rowers, R2=0.31 for runners). T-test results pointed out no statistically significant difference between Astrand and maximal ergometry results in both of the observed groups (p=.42 for rowers and p=.27 for runners), while stronger F-test proved otherwise (p=.00 rowers; p=.01 runners). Acquired results confirmed that Astrand test can not be considered an accurate test for evaluation of the aerobic capacity in recreational rowers and runners. For further research, it remains to be investigated can these results be translated to a broader population of the physically active men in their middle age
