Effects of physical fitness training on metabolic syndrome among military personnel in Taiwan

IntroductionMetabolic syndrome (MS) is strongly associated with cardiovascular diseases and diabetes but can be prevented with regular physical activity. This study aimed to assess the impact of a physical fitness training programme on MS among military personnel.MethodsThis retrospective observational study included volunteer army soldiers who underwent annual health examinations between 2011 and 2014. In 2011, the reformed physical fitness training programme and physical fitness test were introduced to the participants. MS evaluation and physical fitness performances were evaluated before and after implementing the training programme using a mixed-effects model and generalised estimating equation, adjusted for sex, age and smoking.ResultsFrom 2011 to 2014, 1720 soldiers underwent the annual health examination. In 2011, before the fitness programme, 246 soldiers (14.3%) had MS. After implementation, decreases in blood pressure and fasting glucose levels were observed and maintained for 3 years. Running performance was negatively correlated to triglycerides (ß=−11.37; pConclusionsMS and its components improved after introducing the reformed fitness programme, with running performance proving to be most relevant to MS. Clinicians should encourage increased physical activity to prevent MS among military personnel.
