The purpose of the present study was to examined the effects of a 12-min cold water immersion(CWI) on each of, core
temperature (Tc), oral temperature (To), heart rate (HR) and running distance covered performance in the second trial in
a hot environment. Ten participant (mean age 30.5±5.54 years ; height 1.84.1±5.10 ; body mass 76.62± 9.48 kg,)
completed two testing sessions separated by one week; each trial consisted two bouts of a 30-min running on hot
condition (30.90°±1.28°C, 72.6±5.68% relative humidity). The two bouts were separated by either 22 min of seated
recovery in the heat (non-CWI) or the same condition with 12-min CWI(mean 15±1°C (5th–17th minute). HR, Tc, To
and distance in second bout were recorded throughout the testing sessions. There was a significant incline in
performance-trial from Test1 to Test2 using CWI (7010 ± 495.92 m) compared to the change seen non-CWI (6887±
490.42). (Tc) was reduced following non-CWI (37.94 ±1.0ºC) compared with CWI (37.52 ± 0.4 ºC). The total HR
during the non-CWI and CWI test was (96.50 ± 14.27pbm) (decline range 84.7 pbm) and (84 ± 9.84 pbm) (decline range
93.5pbm), respectively. (To) no deferent between non-CWI recovery (36.50±.318ºC) ,compared to the change seen CWI
(36.50±.405ºC). 12-min cold-water immersion recovery significantly lowered (Tc) and maintained endurance
performance during second test session . These data indicate that repeated exercise performance in heat may be
improved when a short period of cold-water immersion is applied during the recovery period.
