Maximal oxygen uptake in athletes.

Abstract
During maximal running (treadmill) or bicycling the O2 uptake was determined in 95 males and 38 female athletes belonging to Swedish National Teams. The mean maximal O2 uptake for the 15 males with the highest values was 5.75 liters/iflin with an upper extreme of 6.17 liters/min. The mean maximal pulmonary ventilation was 158.7 (140.0-203.3) liters/min and the mean maximal heart rate 185 (169-200) beats/min. As a team the 5 cross-country skiers achieved the highest value 83 ml/kg Xmin (5.6 liters/min) and the highest individual value (AR, world champion in cross-country skiing) was 85.1 ml/kg x min (5.7 liters/min). Subject KK (8,QQ0 m, 7:39.6) had 82 ml/kg x min (4.9 liters/min). Tha maan maximal O2 uptake for the best 10 female athletes was 3.6 liters/min. The maximal pulmonary ventilation was 111.8 (91.6-131.0) liters/min and maximal heart rate 195 (185-204) beats/min. A description of the system for collection of expired air is also given.
