Aims & objectives: The aim of the present research was to determine the effect of aerobic exercise training on blood lipid profile in young adults. The path physiology of blood lipid in young adults its increase the atherosclerosis formation on the coronary artery and during the physical inactivity results it developed cardiac diseases. Therefore use of aerobic exercise will be helpful in setting up a better aerobic exercise protocol for improving the lipid profile level and prevention of cardiac disease. Methodology: This experimental study was carried out with 6 subjects including both male and female with age 20- 30year at college of Himalayan hospital. The data is collected by taking outcome variables in form of blood lipid profile level, BP, THR time. Protocol: Aerobic exercise 30 minute session/ 5 days/ weeks for 4 weeks with 60 – 70 %THR. Data analysis: Data was analyzed with parametric test in form of T-test which required with a significant level set at (pd”0.05) and confidence interval was 95%. Result: There was a beneficial effect of exercise on HDL variables, BP, & THR seen most clearly with the 4 week of aerobic exercise training, other than HDL, BP &THR no other variable has been able to differentiate among both groups. Discussion: The increase in HDL and decreases the BP, THR time among both group after the aerobic exercise training. Minimal weekly exercise increases the HDL level. BP & THR time are due to the parasympathetic activity. Conclusions: Aerobic exercise is widely believed to induce changes in the lipid profile, BP & THR time of subjects. 

Key words: Aerobic exercise training; Blood lipid profile level; HDL (high density lipoprotein); BP (blood pressure) and THR (target heart rate) & cardiac disease.
