摘要

胰島素敏感度降低與自主神經活性的改變為老化過程中造成影響健康的重要因子。本研究之目的為探討退役女性運動員之身體活動量、胰島素敏感度與自主神經調控之間之相關性。研究方法為以12名中年退役女子籃球選手，根據身體活動習慣將退役運動員分為無運動習慣組（sedentary ex-athletes，SA）與具有運動習慣組（physically active ex-athletes，PAA），並以8名年輕女性現役籃球選手作為年輕對照組（young control，YC）。全體受試者均以七日身體活動回憶問卷、口服葡萄糖耐受度試驗與心率變異度分別測量受試者之身體活動量、葡萄糖耐受度度與自主神經活性。研究結果顯示PAA組身體活動量顯著高於SA組。於血糖控制方面，相較於SA組，YC組葡萄糖曲線下面積顯著較低，且PAA組也顯著低於SA組。於心率變異度方面，SA與PAA組之總、高頻與低頻功率顯著低於YC組。除此之外，退役運動員之身體活動量與葡萄糖曲線下面積呈顯著負相關，但與自主神經活性無顯著相關。本研究結論為提高身體活動與維持胰島素敏感度有關，但是無法恢復因為老化過程造成之自主神經活性改變。

Decreased insulin sensitivity and parasympathetic nerve activity play an important role in physical wellbeing during aging. The purpose of this study was to investigate the association among physical activity, insulin sensitivity, and autonomic nerve control in retired female athletes. Twelve middle-aged retired female basketball players were divided into sedentary ex-athletes (SA) and physically active ex-athletes (PAA), according to their physical activity habits. Eight college athletes were recruited as young control (YC) subjects. Physical activity, insulin sensitivity and autonomic control were measured by a 7-day physical activity recall, oral glucose tolerance test and heart rate variability respectively for all subjects. In the results we found that PAA group had higher physical activity compared to SA. In addition, glucose area under the curve (GAUC) in YC and PAA were significantly lower than that in SA. The total power, high frequency and low frequency of subjects in SA and PAA groups were lower than subjects inYC group. Furthermore, physical activity was negatively correlated with GAUC in retired athletes. The correlation between physical activity and autonomic nerve activity was not significantly different. These results demonstrated that increased physical activity was associated with increased insulin sensitivity in retired female athletes, but not with autonomic nerve activity.
