Aim: The aim of the current study was to determine whether gentle body exercise has a positive impact on the HDL and LDL levels of cholesterol and levels of trigyceryl in people aged up to 50 years old with normal body weight. Material and Method: The sample consisted of 40 healthy persons aged up to 50 years old with normal body weight, which they did not have a cardiovascular disease history, a diabetes history, or a hormonal disorder history. Furthermore, those people were found with high levels of triglycelyl and LDL cholesterol, and low levels of HDL cholesterol, in the context of a preventive laboratory control. After they applied a gentle body exercise program, they were re- examined for the determination of the LDL/ HDL cholesterol levels and triglyceryl levels in a time period of three and six months. Results: The application of a gentle body exercise program in the form of walking, led in a gradual decrease of triglyceril levels and LDL levels, and increase of HDL cholesterol levels. Conclusion: The positive impact of body exercise in the metabolism of lipids has already been proved. The decrease of triglyceryl levels and LDL cholesterol levels and the increase of HDL cholesterol levels constitute two of the most important factors for the prevention against atheromatosis development. The application of a gentle body exercise program in the form of walking, as shown in the current study, it can be an acceptable and an applicable way of exercise for a large number of people.
