摘要: The objectives of this study were to (1) assess the effect passive heating upon attention and memory task performance, (2) evaluate effectiveness application cold packs head on preserving these functions. Using a counterbalance design 16 subjects underwent three trials: control (CON, 20°C, 40% rH), hot (HOT, 50°C, 50% rH) with kept cool (HHC). In each condition, tests two performed. Mean core, forehead tympanic temperatures all significantly higher (p< 0.05) during HOT (38.6° ±0.1°, 39.6° ±0.2° 38.8°±0.1°C, respectively) HHC (38°±0.2, 37.7°±0.3° 37.7°C, than in CON (37.1°±0.6°, 33.3° 35.9°±0.3°C, respectively). Results indicate that there was impairment working heat exposure (p < without alteration attentional processes. regular only prevented detrimental hyperthermia short-term memory. Our results show impairments cognitive function beneficial cooling are dependent suggests environment is competing variable
