Changes in maximal cardiorespiratory capacity and submaximal strain while exercising in cold

摘要

Sixteen subjects were exposed to varying climatic conditions (20 to -20 degreesC) while exercising with different intensities from light to maximal. The results indicate that maximal cardiorespiratory capacity is lowered and submaximal strain is increased when ambient working temperature decreases. This means that the individual strain caused by a given submaximal workload may be significantly higher in cold as compared to thermoneutral environment due to cooling, use of additional clothing or their combination.
