anxiety; cold; cooling; electrocardiography; heart rate; hypothermia; males; precooling; sympathetic nervous system
Abstract:
... This study examined the effect of mild hypothermia (a 0.5 °C decrease in rectal temperature) on heart rate variability (HRV), with the identical hypothermia protocol performed twice and compared using intraclass correlation coefficient (r) analysis to study the repeatability. Twelve healthy males each completed 1 neutral (23 °C) and 2 cold (0 °C) trials. In the neutral trial, participants sat quie ...

Subject:
body temperature; breathing; carbon dioxide; exercise; food intake; males; metabolism; oxygen; peak oxygen uptake; skin temperature; tidal volume
Abstract:
... Food intake increases metabolism and body temperature, which may in turn influence ventilatory responses. Our aim was to assess the effect of food intake on ventilatory sensitivity to rising core temperature during exercise. Nine healthy male subjects exercised on a cycle ergometer at 50% of peak oxygen uptake in sessions with and without prior food intake. Ventilatory sensitivity to rising core t ...

Abstract:
... High-intensity interval training (HIIT) is known to be an effective exercise training regimen to improve energy substrate metabolism and insulin sensitivity. However, the underlying mechanisms of improvement in insulin sensitivity due to HIIT have not yet been fully clarified. C1q/tumor necrosis factor-related protein (CTRP) 1 and CTRP9, which are adiponectin paralogs and novel adipokines, have fa ...

Abstract:
... Nutritional recovery of early malnutrition with a soybean diet reduces liver glycogen stores in the fed state and produces liver insulin resistance. We investigated whether nutritional recovery on a soybean flour diet alters hepatic gluconeogenesis in the adult offspring of rats deprived of protein during pregnancy and lactation. Male rats from mothers that were fed either 17% (C) or 6% (L) protei ...
