近年來身體活動量與健康相關議題備受關注，過去研究指出身體活動量越多有助於降低心血管、糖尿病等代謝症候群疾病。
本研究目的以瞭解民眾之運動時段對於整體身體活動量、睡眠時間、生化指標之關聯性。本研究結合問卷、尿液與血液檢體和計步器為研究工具，研究對象為年滿18歲以上前往雲林某醫院之成年民眾為對象。我們採橫斷式調查法包含之總樣本為307人，並採用SPSS22.0統計軟體進行資料處理與統計分析。 本研究結果指出性別和運動組別與身體活動量之間具有顯著差異存在。另外，運動時段組別與睡眠時間之間具有顯著差異。在運動時段組別與生化指標之間，結果指出只有在三酸甘油脂(p<0.05)、腎絲球過濾率(p<0.01)指標具有顯著差異。本研究也發現我們的樣本數當中，以習慣下午運動的人活動量為最低；在早上運動習慣的人，雖然睡眠時間較短，但相對在午間睡眠需要比較長的時間；習慣在下午運動的人，雖然睡眠時間較長，但其相對的午間睡眠時間較短。在運動時間步數和百分比對於生化指標之相關性中發現，每個運動時段所具有關聯性的生化指標不同，因此本研究無法判定哪個時段為最佳的運動時段。未來需要更大的樣本數以及縱向的追蹤研究來協助判定運動時段對於生理指標是有助於改善健康，以提供民眾在適合的運動時段上的建議。 Physical inactivity has become an important health issue in recent years, it has been shown that physical activity was related to lower risks of cardiovascular, diabetes and other diseases. The purpose of this study is to examine associations between timing of physical activity, sleep time, and biomarkers. Our measurements included questionnaires, urine and blood samples and pedometer, the study sample included adult aged 18 years or above from a hospital in Yunlin.
We found significant gender differences in the distribution of timing of physical activity. In addition, there was a significant relationship between timing of physical activity and sleep time. Our findings indicated that timing of physical activity were significantly associated with triglyceride (p<0.05), renal filtration rate (p<0.01). We also found that those who tend to exercise more in the afternoon had a lower level of physical activity. Those who tend to exercise in the moning, had shorter nocturnal sleep, duration and relatively long nap duration. On the other hand, those who tend to exercise in the afternoon had longer nocturnal sleep duration, and a relatively shorter nap duration. In summary, timing of physical activity impact biomarkers differently, future research is needed with larger sample sizes and longitudinal design to further clarify associations between exercise time and biomarkers.
