The purpose of this study was to examine the effect of cold water immersion(CWI) on the rate of sweat-loss from the body. Ten participants
(mean age 30.5±5.54 years; height1.84.1±5.10; body mass 76.62± 9.48 kg, Max Vo2. 63.28 ± 6.27 ml/kg/dk) completed two testingsessions separated by one week. Each trial consisted of two bouts of a 30-min running on hot environment (30.90°±1.28°C, 72.6±5.68%
relative humidity). The two bouts were separated by 22 min of seated recovery. During the 22 min, the athlete was immersed in cold
water (mean 15±1°C (5th –17th minute), whereas in the second test he was not immersion to cold water (non-CWI) and the decision of
exposure was made randomly. The average rate-of-sweat lost for athletes after the second half in the CWI test (2833.97±530.64gr) was
less than that of the non-CWI test (3239.97 ± 580, 26 gr) during a 60-min running in the track. The water volume consumed during the
test was highly variable (649.97± 328.81 gr; 653.97±285.49 gr) but there was a strong relationship between the rate of sweat loss and
water volume consumed for non- CWI, while there was no strong relationship on CWI test. Total drink volume consumed during the
both was the same, but a sweat rate for CWI was less than non-CWI. The results indicate that running in hot and humid environment
the body loss fluids. This can cause a sodium defcit among many athletes. The researcher recommends to use cold water immersion
to improve exercise-performance in high temperature and humidity.
