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 degrees C, 30 degrees C and 40 degrees C of air temperature in a climatic chamber. The most valid prediction equation for young adult females was developed as VO2 max =[95.182VO2/(0.763Ve-1.092Wt-1.542Yr+16.82VO2+0.361OR+0.110Ht+63.655)]+0.126, and the one for young adult males was determined as V02 max =[87.919VO2/(0.484Ve-0.583Wt-1.354Yr+0.295OR+12.15VO2-0.110Ht+81.009)]+0.434 using the oxygen intake (VO2), pulmonary ventilation (Ve), ratio of oxygen removal (OR) during submaximal test work and body weight (Wt), stature (Ht) and age (Yr) of subjects.
