The rate of excretion of sweat proteins during sweating was studied under different experimental conditions in healthy Nigerian and Caucasian males. Samples of sweat collected from subjects sweating in a climatic chamber were spectrophotometrically analysed for their protein concentrations using Biuret reagents. The rate of sweat protein losses were found to increase with exercise and raised temperature conditions. The rate also increased with increase in sweat rate and duration of sweating under the exercise condition. However, with the raised temperature conditions, protein loss decreased with increase in sweat rate and with duration of sweating. It was found that the more the sweat protein lo s. the higher the pH value of the sweat (r=O. 96), with a tendency towards alkalinity. The findings suggest that the amount of proteins in sweat modifies the quality of sweat under various conditions of thermal stress and their elimination from the body is affected by the level of body heat load. Nigerians had 30% lower rate of water loss and I 0 to 20% higher rate of sweat proteins and sweat electrolytes than their Caucasian counterparts.
