Effect of Number of Days of Resistance Exercise on Blood Lipids in Korean Adults : Using the 2022 National Health and Nutrition Examination Survey

The present study aims to investigate the effect of the number of days of strength training on blood support components in Korean adults. The data utilized in this study were collected from a study that was conducted with the approval of the Research Ethics Review Committee of the Korea Centers for Disease Control and Prevention. The subjects were divided into two age groups: young people and middle-aged people, according to their life cycle. The elderly group was divided into three groups based on the number of days per week spent engaged in strength training. The groups were as follows: a group that did not exercise at all, a group that exercised 1-2 days per week, a group that exercised 3-4 days per week, and a group that exercised more than 5 days per week. A statistical analysis was conducted using the SPSS program, which revealed significant differences in fasting blood sugar, total cholesterol, LDL cholesterol, and neutral fat across all subject groups depending on the life cycle. Additionally, the analysis demonstrated significant differences in HDL cholesterol only in the elderly, young people, and middle-aged. Significant differences in blood lipids were observed depending on the number of days of strength training. Specifically, HDL cholesterol and triglycerides exhibited notable variations. The group that engaged in strength training for 3 to 4 days demonstrated significantly different levels of both factors compared to the group that did not exercise at all. These findings suggest that strength training 3 to 4 times a week may offer a more favorable impact on blood lipids than less frequent training or no training at all.
