Self-efficacy of Doing Physical Exercise in People at Risk of Coronary Heart Disease

Abstract

Physical activity affects the body's mechanisms and increases high -density lipoprotein (HDL) levels, lowers low-density lipoprotein (LDL) levels in the body, increases glucose metabolism by increasing insulin sensitivity and reduces excess fat levels and high blood pressure. Self-efficacy affects behavior changes, individuals and as a stimulus for activity. The purpose of this study was to determine the effect of health education on self-efficacy of doing physical exercise in the intervention group and the control group.
 This study was quantitative with a quasi-experimental control group pre-post test to compare the intervention in the control and intervention groups, then the difference between the pre-test and post-test was assumed to be the effect of the experiment. The control group received the leaflet intervention model and the intervention group received the guided education model and videos. Samples are people in the village Kopiwangker and Taraitak who met the inclusion criteria with the number 70.
 The results showed a significant value scores before and after intervention Intervention group with a value of 0.00 (paired t test) Thus there is the effect of interventions using guided educational models and video media on self-efficacy of doing physical exercise, with a p value of 0.0001. (t independent test). Conclusion There is a significant difference in self-efficacy between the control and intervention groups before and after being given education with different methods. This means that the guided education method/model using video media greatly affects the self-efficacy of doing physical exercise in people at risk of coronary heart disease.
