Prediction of maximal oxygen intake over a wide range of air temperature conditions

The correction of air temperature effect and the amendment of underestimation are two difficult problems for accomplishment of prediction of maximal oxygen intake from a simple submaximal test. The purpose of this study was to develop the prediction equation applicable over a wide range of air temperature conditions with no tendency of underestimation. Submaximal data were obtained from short exposure experiments to 20°C, 30°C and 40°C of air temperature in a climatic chamber. The most valid prediction equation for young adult females was developed as V(O2)max = [95.182 V(O2)/(0.763 Ve-1.092 Wt-1.542 Yr +16.82 V(O2) +0.361 OR +0.110Ht +63.655)] +0.126, and the one for young adult males was determined as V(O2) max = [87.919 V(O2)/(0.484 Ve-0.583 Wt - 1.354 Yr +0.295 OR +12.15 V(O2) -0.110 Ht +81.009)] +0.434 34 using the oxygen intake (V(O2)), pulmonary ventilation (Ve), ratio of oxygen removal (OR) during submaximal test work and body weight (Wt), stature (Ht) and age (Yr) of subjects.
