Exercise and Leukocyte Redistribution

運動與白血球再分配

Abstracts


本篇綜評旨在陳述運動如何經由激活交感神經系統(sympathetic nervous system)和丘腦下部-腦垂體-腎上腺軸(hypothalamic-pituitary-adrenal-axis)而影響白血球再分配(leukocyte redistribution)。摘要言之,長時間運動中所出現之立即性白血球增多(leukocytosis)主要肇因於較高之血漿兒茶酚胺(catecholamines)濃度,而延遲性嗜中性球增多(delayed neutrophilia)則受繼之昇高之血漿皮質固醇(cortisol)所影響。此外,生長激素(growth hormone)亦會導致循環嗜中性球增多現象。運動中補充碳水化合物有助於維持血漿葡萄糖濃度的穩定,進而促進耐力性運動表現,減緩血漿壓力激素濃度和白血球再分配之波動。

This review was to present an overview of the current knowledge of how exercise affects the leukocyte redistribution via stimulation of sympathetic nervous system and hypothalamic-pituitary-adrenal-axis. To summarize, the immediate leukocytosis during prolonged exercise is mainly due to elevated plasma catecholamines levels, whereas the delayed neutrophilia is from the influence of elevated plasma cortisol levels. Besides, growth hormone is also partly responsible for exercise-induced neutrophilia. However, carbohydrate supplementation during exercise is beneficial for maintenance of plasma glucose concentrations and then both improving endurance exercise performance and attenuating the elevation of plasma stress hormones and perturbation of leukocyte redistribution.
