The present research arised from the fact that some specialists supposed that cholesterol and triglyceride could play an effective role in creating cardiovascular diseases. In spite of the numerous researches in the field, the question of whether or not triglyceride can lead to cardiovascular disease is still there. Instead, cholesterol has been recognized as a deleterious factor. Medical research findings indicate that there is a strong relationship between the high levels of cholesterol both in blood and in serum and the possibility of heart coronary disease.

In the present study, 15 male physical education students with average age of 24.2 2.17 years, average weight of 64.93 5.12 kg and the average height of 171.6 5.69 cm, voluntarily participated in this quasi-experimental research. The subjects filled out forms indicating their medical, physical and health related background. Then, they were formally invited by the specialists to participate in the experiment.

The fact that the observed t (2.56) was smaller than the critical t (2.997), suggested that an aerobic activity (a single-session, 20 minutes jog) led to no meaningful changes in the serum cholesterol level. The serum cholesterol level increased 3.74% after activity in comparison with cholesterol level before activity. Furthermore, observed t (0.95) was smaller than critical t (2.997). It can be concluded that an aerobic activity leads to no meaningful changes in the blood triglyceride rate. Serum triglyceride level increased 3.44% after activity in comparison with the serum triglyceride level before activity. On the other hand, the correlation between relative body weight and triglyceride and cholesterol levels was not found. The correlation (Pearson coefficient of correlation) calculated from cholesterol level and relative body weight in fasting conditions and from triglyceride and relative body weight amounted to 0.403 and 0.491, respectively. This suggests an average correlation between measured factors and relative body weight.
