ABSTRACT:
Background/Objectives: The purpose of this study was to investigate the effect of physical activity on the health-related quality of life among people with activity limitations for each type of physical activity. Methods/Statistical analysis: The original data used in the research were the health survey data of the Korean National Health and Nutrition Examination Survey (KNHANES) conducted in 2013 and 2014. The research variables of this study were the frequency of participation in each type of physical activity and EQ-5D (Euro Quality of Life-5 Dimensions). Findings: First, in the case of men, there was a difference in the health-related quality of life (HRQL) between the group that did not participate in walking exercise at all and the groups who did so for 3 or 4 days and 5 days or more. For the flexibility exercise, there was a difference in HRQL between the group who did not participate in the exercise at all and the group who participated in it for 1 or 2 days. Second, In the case of women, there was a difference in the HRQL between the group that did not participate in the muscular strength exercise at all and the group that participated in it for 5 days or more. Improvements/Applications: Thus, proper participation in walking and flexibility exercises for males and adequate participation in muscular strength exercises for females are expected to help improve their HRQL.
