The effect of aerobic activity and L-carnitine supplementation on blood lipids

Introduction:
An increase in body fat percentage and blood lipids would threaten the health of the current generation. Several factors can affect the blood lipid profile, among which age, heredity, physical activity, and the consumption of bodybuilding supplements can be mentioned. The main goal of this research was to investigate the effect of a period of aerobic activity (6 weeks) along with L-carnitine supplementation on lipids (triglycerides and cholesterol) and lipoproteins in the blood serum of non-athletic boys in the county of Selseleh.

Material and methods:
In this research, a checklist and note-taking were used to collect information from the field research method and to obtain primary data for analysis and hypothesis testing. The statistical population in this study included 30 non-athletes who were selected by available sampling and randomly divided into 3 groups of 10: the first group (aerobic activity), the second group (L-carnitine-supplement consumption), and the third group (aerobic activity-L-carnitine-supplement consumption).

Results:
For the statistical analysis of data in this study, a semi-experimental, pre-test-post-test method was used. According to the obtained results, it was found that aerobic activities alone can reduce blood serum lipids and lipoproteins, and taking L-carnitine supplement can reduce blood serum lipids, but it did not have a positive effect on reducing lipoproteins.

Conclusions:
According to the results, aerobic activity is the most effective approach for the reduction of blood serum lipids and lipoproteins rather than the 2 other approaches.
