Abstract
The purpose of this study was to investigate effects of treadmill walking associated with wearing firefighting equipment on heart rate, rating of perceived exertion (RPE), and electroencephalogram activity (alpha wave, beta wave). The subjects of this study included ten male college students (age: 23.80±3.33 yrs, height: 178.70±4.62 cm, weight: 78.70±6.00 kg), who were subjected to firefighting protective equipment (FET) and contrast (CON). The exercise protocol was carried out using a treadmill at a speed of 5 to 6 km/h, an exercise time of 15 minutes, and a gradient of 11°. The results of our study are as follows : 1) Heart rate and RPE showed that FET was higher than CON at all times during exercise. 2) Alpha waves increased significantly in the right temporal lobe region (T4, P 8) after the firefighting in FET. 3) Beta waves showed higher activity than alpha wave before the experiment, although there were no statistically significant changes. Therefor, alpha wave is activated by the increase of exercise intensity in FET, and the wearing of firefighter turnouts activates beta wave by bringing tension and stress. Further research should be done for firefighters to classify their fitness and career, and to study the changes in brain wave applying the fire situation in virtual reality.
