Abstract: (1076 Views)
Background: In heat stress management, the reduction of body heat load is important. The purpose in this study was the examination of the cooling ability of an ice gel cooling vest in hot and dry conditions.Methods: This interventional experiment was conducted on 12 healthy male students. The heat strain score index (HSSI), skin temperature, oral temperature, and heart beat were measured with and without the cooling vest and two exercise intensities of 2.4 and 4.8 km/hour during 30 minutes in a climate chamber. The air temperature and humidity in the climate chamber were 38.8 °C and 32.9%, respectively. Data were analyzed using the independent t-test and repeated measures.Findings: The averages of chest skin temperature and HSSI with and without the cooling vest were significant in the speed of 2.4 km/hour (P < 0.005); however, these means were not significant in the speed of 4.8 km/hour. Moreover, no significant difference was observed in mean heart rate, oral temperature, and scapula skin temperature in the two speed rates.Conclusion: The findings of the study indicated that the ice gel cooling vest can reduce skin temperature and HSSI in light activities compared to moderate activity in hot and dry climatic conditions.
