Yoga exercise, which is used for health, fitness and injury treatment, has been shown to be effective for improving the quality of life of diverse groups in various studies.South Korea is one of the OECD countries with the longest working hours. Therefore, it is not easy to spend a lot of time in activities for your health. The purpose of this study was to investigate how twice a week yoga exercise affect the quality of life in women with metabolic syndrome in Korea.
Participants were assigned to the yoga exercise group (n=17) or the control group (n=20). The yoga exercise program was conducted 60 minutes, twice a week for 3 months by the yoga exercise group. The quality of life of both groups was assessed using the EuroQoL-5 Dimension (EQ-5D) and the EuroQoL Visual Analogue Scale (EQ-VAS). Student’s t-test or Mann-Whitney test was used to compare the general characteristics of the participants, while analysis of covariance (ANCOVA) was used to compare the quality of life indicators both before and after yoga exercise between the groups that performed yoga exercise and those who did not.
EQ-VAS tended to increase more in the yoga group than in the control group (yoga group 76.29±13.10, control group 70.50±15.21, P=0.064), but it was not statistically significant. However, there was no statistically significant difference in EQ-5D scores (yoga group 0.88±0.10, control group 0.91±0.07., P=0.762) between the two groups when we compared the quality of life indicators from before and after the yoga exercise.
The yoga, which lasts for one hour twice a week for three months, may increase the quality of life in middle-aged women with metabolic syndrome. Further researches that more often and more longer period of yoga exercise are needed to establish the exact effect of yoga on quality of life in women with metabolic syndrome.
