Combined effects of fabric air permeability and moisture absorption on clothing microclimate and subjective sensation during intermittent exercise at 27 degrees C

Article Abstract:

The combined effects ot two different rates of air permeability and moisture absorption with regard to clothing microclimate and subjective sensation amongst resting and exercising subjects at a temperature of 27 degrees C, were assessed. The three types of clothing were polyester with low moisture absorption and low air permeability (A), polyester with low moisture absorption and high air permeability (B) and cotton with high moisture absorption and high air permeability (C). Microclimate humidity in the back area was higher in A than in B, and in C than in B. In the chest area the microclimate temperature was higher in B than in A, and in B than in C.

The influence of exercise intensity on sweating efficiency of the whole body in a mild thermal condition

Article Abstract:

Exercise intensity fails to affect the sweating efficiency of the body in mild thermal conditions. Changes in sweating efficiency with increasing exercise intensity depend on the environmental conditions. The rectal temperature and mean skin temperature increase with an increase in the exercise intensity, at the end of exercise. The heat loss by evaporation, radiation and convection increase during the exercise. The results of a study on six healthy males performing three bicycle ergometer exercises at varying intensities are discussed.
