| Abstract: | 背景：2018年世界衛生組織指出：「肥胖是一種慢性疾病」，目前全世界超重或肥胖問題約佔30％，不僅影響外觀、體態及體脂肪量，對健康的危害會誘發多種慢性疾病。而近幾年發展出高強度間歇訓練模式(high-intensity interval training,HIIT)，許多研究已證實高強度間歇訓練模式能在短時間內提升有氧代謝能力，對降低體脂肪及改善代謝症候群具有較好的效果，故本研究目的為採用系統性文獻回顧及整合分析。
方法：納入研究文獻搜尋3個英文資料庫是PubMed、Cochrane Library、EBSCO，與2個中文資料庫華藝線上圖書館(Airiti Library)、中國知網(China National Knowledge Infrastructure, CNKI)。搜尋中英文關鍵字包括「高強度間歇訓練」、「high-intensity interval training」，與「體脂肪」、「Body fat」、「adipose」、「肥胖」、「obesity」及「fat」等的交集，搜尋時間至2019年1月8日止，並採用RevMan 5軟體進行收集文獻的系統性回顧與整合分析。
結果：本研究的系統性文獻回顧納入14篇隨機對照試驗文獻，其中10篇研究中高強度間歇訓練組有147名，無訓練對照組有141名可進行分析。整合結果比較HIIT組與無運動控制組的前後變化值的加權平均差異值(WMD），發現HIIT組較無運動控制組顯著降低體脂肪為-2.49%（95%CI:-2.99,-1.99）;身體質量為-2.18kg (95%CI:-3.20,-1.16）; 脂肪量為-2.97kg （95%CI:-4.43,-1.52），而且三個整合分析皆無顯著異質性存在，且皆無發表誤差。
結論：經整合分析後，相較於無運動的對照組，高強度間歇訓練模式會顯著降低體脂肪、身體質量與脂肪量。
Background: In 2018, World Health Organization raised warning, "obesity is a chronic disease." At present, the overweight or obesity of the world were high to 30%, not only to affect the appearance, body and body fat, but also to be the health hazards and induce a variety of chronic diseases. In recent years, high-intensity interval training (HIIT) had been developed and many studies had suggested that this training mode could improve aerobic metabolism in a short period of time, and contribute to reduce body fat and improve metabolic syndrome. The purpose of this study is to explore the reducing body effect of high-intensity interval training mode by using systematic review and meta-analysis.
Methods: The searching databases includes three English (PubMed, Cochrane Library, and EBSCO databases) and two Chinese (Airiti Library and China National Knowledge Infrastructure). The searching English and Chinese keywords included "High Intensity Interval Training" and " High-intensity interval training”, intersecting with ‘body fat’, ‘adipose’, ‘obesity’ and ‘fat’ until January 8, 2019. The RevMan 5 software was used for systematic review and meta-analysis.
Results: This study included 14 articles for systematic review and 10 articles including 147 in HIIT group and 141 in non-exercised control group for analysis. The results of meta-analysis were weighted mean differences(WMD) compared mean differences of pre-post effects between two groups, and demonstrated that HIIT group significantly reduced more body fat (-2.49%, 95% CI: -2.99 , -1.99）, body mass (-2.18 kg, 95% CI: -3.20 , -1.16）, and fat mass（-2.97 kg , 95% CI: -4.43 , -1.52）than non-exercise control group. These three meta-analysis were non-heterogenetic and non-publication bias.
Conclusions: Results of meta-analysis show that there were significant effects on reducing body fat, body mass and fat mass among the high-intensity interval training group compared the non-exercise control groups. |
