Obesity, but not hypohydration, mediates changes in mental task load during passive heating in females.

摘要: Background The independent effects of hypohydration and hyperthermia on cognition mood is unclear since the two stresses often confound each other. Further, it unknown if obese individuals have same impairments during that observed in non-obese individuals. Methods current study was designed to assess combined mild cognition, mood, mental task load females. Twenty-one healthy females participated passive heating trials, wherein they were either euhydrated or hypohydrated prior throughout heating. Cognition (ImPACT), (NASA-TLX), (Brunel Mood Scale; BRUMS) measured before after a 1.0 °C increase core temperature (TC). Results After TC elevation, resulted greater (p 0.05). Hyperthermia, regardless hydration status, impaired (∼5 A.U) measures memory-based (verbal visual memory), increased load, while worsening Conclusion These data indicate independently impairs aspects cognitive performance, leads negative state. Mild did not exacerbate hyperthermia. However, had
