運動訓練特性對自主神經系統與血糖控制能力的影響
Alterations in the Homeostasis of Autonomic Nervous System and Blood Glucose Levels across Different Sport Disciplines
摘要
耐力型運動選手血糖控制能力優於爆發力型運動選手，單次不同的運動方式對運動後自主神經系統的恢復也有所不同，本研究目的欲探討不同運動項目對自主神經系統與血糖控制能力的影響。募集保齡球、橄欖球前鋒、橄欖球後衛及足球選手各10位，測量身高、體重、腰圍、臀圍、空腹血糖及胰島素，進行口服葡萄糖耐受度測驗及胰島素敏感性測驗，並測量安靜、運動後和運動後5分鐘恢復期的交感神經及副交感神經活性。本研究結果為橄欖球前鋒選手身體質量指數和腰臀圍比為四組最高，足球選手在四組內最低。血糖吸收能力和胰島素敏感性橄欖球後衛選手最佳，而保齡球選手最差。保齡球選手在運動後恢復期的交感神經活性高於其他三組，而副交感神經顯著低於其他三組。本研究結論為長期規律性高強度訓練的選手胰島素敏感性及運動後自主神經回復能力明顯優於無規律運動訓練的保齡球選手，未來著重穩定性的運動項目也可以藉由高強度運動訓練來提升自主神經的控制，進而提升穩定性運動項目的運動表現能力。

Autonomic nervous activity is one factor influencing insulin sensitivity. The present study was designed to investigate the alterations in the homeostasis of autonomic nervous system and glucose levels across various types of athletes. We recruited four disciplines of athletes including bowling (n=10), rugby-forwards (n=10), rugby-backs (n=10), and soccer (n=10) for this study. Body weight, high, waist, hip, fasting blood glucose, fasting plasma insulin, glucose tolerance and insulin sensitivity were measured. Sympathetic and parasympathetic nerve activities at rest and post-exercise were measured by heart rate variability. Higher BMI (body mass index) and WHR (waist hip ratio) values were found in rugby-forward players, and lower BMI and WHR values in soccer players were found compared to the rest of groups. Glucose uptake and insulin sensitivity were improved in rugby-back players, while, the same were lower in bowling players. Sympathetic nerve activity at post-exercise 5-min was higher and parasympathetic nerve activity was lower in bowling players than that of other groups. This data suggests that high intensity exercise training is beneficial in improving the performance by maintaining the stable autonomic nervous system in players.
