A depletion of body fat has been reported by several investigators for various species of homoiotherms exposed to chronic acceleration. Generally the effect is proportional to field strength, and over the size range examined (0.25-5 kg) it becomes more severe in larger animals. There is some evidence that this may be the result of increased secretion of a pituitary hormone, the fat mobilizing substance (FMS). An exception to the defatting effect of chronic acceleration was observed in mature pig-tailed monkeys (Macaca nemestrina)--although they exhibited other changes generally found in homoiotherms exposed to hyperdynamic environments. It is considered that this unusual primate response to chronic acceleration may result from a different geometry of the central nervous system, and its effect upon gravity load distribution in the lower part of the brain.
几位研究人员报告称,多种恒温动物在长期加速作用下会出现体脂减少的情况。一般来说,这种影响与场强成正比,在所研究的体型范围内(0.25 - 5千克),体型较大的动物受影响更严重。有证据表明,这可能是垂体激素——脂肪动员物质(FMS)分泌增加的结果。在成年猪尾猴(食蟹猕猴)身上观察到了长期加速脱脂作用的一个例外情况——尽管它们表现出了一般在处于高动力环境的恒温动物身上发现的其他变化。据认为,这种灵长类动物对长期加速的异常反应可能源于中枢神经系统不同的几何结构,以及其对大脑下部重力负荷分布的影响。
