Sweat Rate Study


The results of our study suggest that sweat rate may be lower in non-elite marathon runners compared to elite runners. The mean sweat rate at the end of 1 hour was 1.4 l/hr which was body mass loss of approximately 1.9% (for mean body weight of 71.6 kgs before start of the run). Using this background of baseline sweat rate data further studies on electrolyte imbalance and fluid replacement strategy for these non-elite runners should be performed.
