代謝症候群會增加罹患心血管疾病、腦血管疾病及糖尿病的危險性，其盛行率逐年上升。低身體活動量者較高身體活動量者罹患代謝症候群的風險增加，學者建議提高身體活動、接受運動訓練或改變生活型態。以改善身體組成、血壓、血脂和血糖，以減少代謝症候群的危險因子，來預防與治療代謝症候群。常見的介入方式包括單獨使用中高強度的有氧運動、阻力運動或合併有氧與阻力運動，或再搭配飲食療法，如控制熱量、減少膽固醇或脂肪攝取等，以及其他更多生活型的改變。代謝症候群患者的運動處方與一般健康成人相似，同樣需防運動產生的肌肉骨骼系統的症狀或併發症。對具代謝症候群危險因子或確診者，希望運動訓練或生活型態改變後，可改善身體組成，如體重、腰圍或體脂肪下降，進而降低罹患代謝症候群的危險性和其他相關疾病的罹病率。然各研究的對象，收入條件存在差異、介入時間長短不一、後續追蹤時間多有不同，尤其是生活型態的改變層面差異大，以致運動訓練及/或生活型態改變在血壓、血脂或血糖調控之成效成果常不一致，個參數間的相關性也有待更多研究去探討。

Metabolic syndrome increases the risks for cardiovascular diseases, cerebrovascular diseases and diabetes mellitus. Its prevalence has been increasing over years. People with low physical activities have higher risk of metabolic syndrome than those who have higher level of physical activities. Lifestyle modifications and higher levels of physical activities or exercise training are recommended to reduce the risk factors of metabolic syndrome, such as improving body composition, blood pressure, lipid profiles and blood glucose control, thus preventing metabolic syndrome or slowing down its progression. Common interventions for metabolic syndrome include moderate-to-high intensity aerobic, resistance, or combined exercises with or without diet and other Iifestyle modifications, such as calorie control and reduction of cholesterol and fat intake. Exercise prescription for patients with metabolic syndrome is similar to those of general adults. Supervision is necessary in order to prevent musculoskeletal complications or adverse events. Population with metabolic risk factors as well as those with metabolic syndrome has been shown to benefit from some improvements in body composition, reduction in body weight,waist circumference or body fats following exercise training or lifestyle modifications, and hopefully with lowered risks of metabolic syndrome and morbidities of other related diseases. However,the characteristics of study population, duration of intervention and fol1ow-up as well as the mode of lifestyle modifications differed among current studies, and the effects of exercise training and/or lifestyle modifications were being inconsistent. Future studies are required to investigate the relationships between the aforementioned parameters. (FJPT 2012;37 (2):91-103)
