Physiological, psychophysical, and psychological responses of firefighters to firefighting training drills.

摘要: This study was designed to describe the physiological, psychophysical, and psychological responses of firefighters firefighting drills in a training structure containing live fires. Fifteen male firefighters, wearing standard turnout gear which resulted full encapsulation, performed two tasks (advancing fire hose, chopping wood) while inside structure. Measurements heart rate, tympanic membrane temperature, blood lactate, perceptions respiration, mood, perceived exertion, thermal sensation were obtained after 8 min advancing again chopping. Heart rate temperature increased significantly from baseline hose wood chopping, whereas lactate initially remained elevated at end task. At completion test (both tasks), mean (182.3 b.min-1), (40.1 degrees C, [104.1 F]), (3.8 mMol) suggested that used this impose considerable physiological strain on firefighters. Psychophysical data mirrored greater following hot environment gear. Language: en
