Effects of Qigong Exercise on Biomarkers and Mental and Physical Health in Adults With at Least One Risk Factor for Coronary Artery Disease

Abstract

Current medical technology permits the early detection of risk factors for coronary artery disease (CAD) in adults, and interventions are available to prevent CAD-related morbidity and mortality. The goal of this study was to determine the effectiveness of a Qigong exercise intervention in improving biomarker levels and mental and physical health outcomes in community-dwelling adults diagnosed with CAD risk factors, in a southern Taiwanese city. Participants were randomly assigned to an experimental (n = 84) group that participated in a 60-min Qigong group session 3 times per week for 3 months or a control (n = 61) group that did not receive the intervention. Self-perceived mental and physical health assessed with the Chinese Health Questionnaire-12, and body fat percentage were measured at baseline and 6, 12, and 16 weeks. Blood samples were collected at baseline and 12 weeks for analysis of lipid profiles, high-sensitivity C-reactive protein (hs-CRP), glycated hemoglobin (HbA1c), and fasting plasma sugar. Linear mixed model analyses revealed that experimental participants had significantly improved perceived mental and physical health and body fat percentage compared to the control group at 6 and 12 weeks but not 16 weeks. The lipid profiles were significantly more improved in the Qigong group than in the control group at 12 weeks. Qigong exercise, however, had no significant effects on hs-CRP, HbA1c, or fasting plasma sugar. Findings suggest that Qigong exercise improves a limited number of CAD risk factors in community-dwelling adults aged 40 years and over.
