Abstract

Aim of this study was to determine the impact of height on the prediction of the maximum oxygen consumption in active young men. The subjects of this study were 20 active young men who were selected and assigned to two groups of short (n = 10, age (year) = 20±2.5, height (cm) = 159.62±4.16, weight (kg) = 61.2±4.38) and tall (n = 10, age (year) = 21.45±3.161, height (cm) = 183.20±3.19, weight (kg) = 80.33±5.12). To explore the impact of height in the prediction of maximum oxygen consumption, the Queen’s step test and the incremental maximal treadmill test were used. Respiratory exchange was measured continuously throughout the test by an automated open-circuit gas analysis system. The results of the study revealed that tall active young men showed higher maximum oxygen consumption on the Queen’s step test than short ones (61±2.94 vs. 52.80±1.81 mL/kg/min). Furthermore findings indicated that on the incremental maximal treadmill test too, tall active young men had higher maximum oxygen consumption than shorter subjects (48.50±3.06 vs. 42.10±2.02 mL/kg/min). According to this study results, we concluded that (1) Queen’s step test overestimates the prediction of maximum oxygen consumption both in tall and short active young men and (2) the higher maximum oxygen consumption observed in tall active young men on the Queen’s step test can not be due to their height alone; therefore, it seems that the higher maximum oxygen consumption in the tall subjects may be due to large amounts of lungs capacity, however, incorporated physiological factors involvement will be require for future studies.
