Effects of Qigong on Adults with at Risk for Coronary Artery Disease
December 16, 2015 -
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 a new study in Taiwan 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.
Eighty-four participants were
randomly assigned to an experimental group that participated in a
60-min Qigong group session 3 times per week for 3 months while 61 were assigned
to the control group that did not receive the Qigong intervention.
Self-perceived mental and physical health assessed with the Chinese Health
Questionnaire-12 and the 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 the Qigong 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.
The findings are published in the November, 2015 issue
of Biological research for nursing.
