背景與目的：國內外研究顯示大學生有近一半睡眠品質不良，而好的睡眠品質與較佳的學業表現有正相關，因此如何改善大學生的睡眠品質成為重要課題。文獻顯示透過運動可以改善睡眠品質，然而並非所有人都適合從事主動性的運動。考量被動性的運動如全身震動訓練(Whole body vibration training, WBVT)與運動有類似的效果，因此本研究想探討WBVT對於大學生睡眠品質、憂慮及焦慮等情況是否可以改善。 材料與方法：本研究以成年大學生為收案對象，預計招募四十位、隨機分派為實驗組和對照組。實驗組進行WBVT，每週三次，每次十五分鐘，連續執行六週，震動訓練儀(BW750)震幅為2 mm、頻率為5.6～13Hz；對照組則不進行任何訓練。每位受試者於訓練開始前進行前測，並於訓練結束後進行後測，評估工具為匹茲堡睡眠品質量表、董氏憂鬱量表及貝克焦慮量表。 研究結果與討論：結果顯示：與對照組相比，六週WBVT對大學生睡眠品質、焦慮與憂鬱之改善表現，均無統計學上的顯著差異(P>0.05)。我們推測運動可以改善睡眠品質與身體活動的總能量消耗有關，而WBVT所消耗的熱量並不顯著，這有可能是此次研究無顯著效果的原因。 結論：目前有大量之文獻研究針對WBVT之改善骨質密度、肌肉平衡與血壓等，但是對於藉由WBVT來改善睡眠品質、焦慮和憂鬱等生活品質與情緒的研究較少。本文以大學生為對象，嘗試以替代運動方法來了解WBVT是否具主動運動之效果，並期許未來研究設計能考慮周密，使研究結果更具顯著意義，因此WBVT是否可加強或是替代主動運動對於睡眠改善的效果，需要更進一步的研究與探討。 Background and Objective: Previous studies have shown that nearly half of the students have poor sleep quality and good sleep quality is positively correlated with better academic performance. Therefore it is an important issue to improve the sleep quality in college students. Researches have shown that exercise can improve sleep quality, but not everyone is suitable for active exercise. Considering that passive exercise such as whole body vibration training (WBVT) and exercise have similar effects, this study try to explore whether whole body vibration training can help college students improve sleep quality, depression and anxiety. Materials and Methods: In this study 40 college students were recruited and randomly assigned to training and control groups. The training group was subjected to whole body vibration training three time weekly for six weeks. The amplitude of the vibration was 2 mm and the frequency was 5.6～13Hz. The control group did not carry out any training. Each subject filled out questionnaires before and after six-week training. The questionnaires were Pittsburgh Sleep Quality Index, John Tung Foundation's Depression Index and Beck Anxiety Index. Results: The results showed that there was no statistically significant difference (P> 0.05) in the improvement of sleep quality, anxiety and depression in training group compared with the control group. We speculate that exercise can improve sleep quality resulting from energy usage during physical activity. Because whole body vibration training does not consume substantial amounts of energy, that is why no significant effect was observed in this study. Conclusion: Many studies have shown that WBVT can improve bone density, muscle strength and blood pressure for patients, but no studies have ever tried to explore if WBVT can improve sleep quality, anxiety and depression. Although this research did not conclude any beneficial effects for training group, we expect that the results will be significant if a better research design can be considered in the future.
