Energy expenditure during moderate work at various climates

The available literature contains conflicting results about the effect of temperature variations on the oxygen consumption of moderate work. This study examines the apparent conflict via a new theory. The theory effectively states that at submaximal work, VO2 is lowest at the acclimatized environmental condition. An experiment is performed at three different dry-bulb temperatures (17.2 degrees C, 33.4 degrees C, and 46.2 degrees C) at a constant relative humidity (68%) to investigate the theory. The oxygen consumption was found to increase consistently with an elevation of the environmental temperature. This finding, in conjunction with results cited in similar studies, supports the theory.
