PURPOSE/OBJECTIVE: Metabolic syndrome (MetS) is a serious public health problem in Hong Kong and worldwide. Older adults, the age by specific exercise modalities that are suitable for regular participation. This project aims to evaluate the effectiveness of Tai Chi to alleviate MetS in older population.~DESIGN & METHODS: This study is a three-arm assesscer blinded randomized controlled trial. Older adults aged 50 years or above with abdominal obesity will be randomly assigned to passive control, active control and Tai Chi groups. Subjects assigned to Tai Chi and active control groups will receive a 12-week intervention of Tai Chi and generic fitness, respectively. No intervention will be given to the passive control group. Outcome measures including waist circumference, blood pressure, blood glucose, triglyceride and high density lipoprotein-cholesterol will be assessed at baseline, post-intervention and follow-up (6 months after the end of intervention) assessments in all groups.~HYPOTHESES: We hypothesize that: 1) improvements of waist circumference and other indicators of MetS are found in Tai Chi group but not in passive control group and 2) improvements of waist circumference and other indicators of MetS are more profound in Tai Chi group than active control group.
Metabolic syndrome (MetS) is a serious public health problem in Hong Kong and worldwide. Older adults, the age group with the highest prevalence of MetS, may prefer specific exercise modalities that are suitable for their regular participation to manage MetS. This project aims to evaluate the effectiveness of Tai Chi, a very suitable exercise for older adults, to alleviate MetS in older population
