摘要

運動與免疫的功能息息相關，適當的運動可以提升免疫力，不過劇烈運動可能會造成免疫抑制。先前研究表示單次運動可能造成免疫系統產生急性變化，其原因包含：淋巴細胞衰退、淋巴細胞分佈改變、荷爾蒙的影響、嗜中性球和淋巴球的外滲作用。其中，荷爾蒙會影響免疫細胞上的受體，改變細胞軟硬度進而影響細胞分配以及數量。目前有氧運動對於免疫反應的影響已有許多研究探討，然而相較於有氧運動的阻力運動受到的影響變項較多（運動強度、訓練量、組間休息或運動時間等），較少研究針對此運動模式進行歸納整理。因此本研究欲初步探討單次阻力運動如何影響免疫細胞數量上的改變。結果發現在中高訓練強度（40～80%-1RM）阻力運動後白血球總量、淋巴球與嗜中性球顯著增加，多數研究並無提及阻力運動之訓練量，根據先前研究整理結果訓練量會影響壓力荷爾蒙的反應，間接影響免疫細胞數量，因此建議未來研究方向可以將訓練量上與強度上做控制，以暸解其他變項對免疫細胞數量的影響，以利調整運動課表。

There is a strong relationship between exercise and immune function. Appropriate exercise is able to increase immunity. However, strenuous exercise might cause the suppression effect on immunity. Previous studies have shown that acute exercise is capable of alternating the immune system. Possible reasons including the declines of lymphocytes, the changes of lymphocyte distribution, the influences of hormones, the extravasation of neutrophils and lymphocytes. In addition, hormones might affect the receptors on the immune cells, change the softness of cells and the distribution as well as number of cells. Due to a more restricted quantifiable variable (VO_(2max)), evidences on the effect of aerobic exercise on immunity are more clear than resistance exercise. Results on the effect of resistance exercise are relatively equivocal due to multiple manipulable variables (exercise intensity, training load, rest time between sets, etc.). Therefore, current study intended to investigate the effect of a single resistance exercise on the number of immune cells.
