Abstract:

Background: Exercise is the first line of treatment used to improve the lipid profile of a person. Lack of exercise will lead to a host of chronic illnesses.

Aim: This study compares lipid profile levels of apparently healthy, regularly exercising young adults with those who did not exercise regularly.

Settings and Design: Christian Medical College, Ludhiana; Comparative study.

Methods: The lipid profile of a cohort of 24 subjects who had been indulging in regular physical activity for 6 months prior to sample collection were compared with 24 subjects who did not exercise. Roche modular P800 was used. Selection was done by simple convenient sampling. Data of their physical activity was collected with the help of global physical activity questionnaire. Statistical analysis was done by ANOVA analysis.

Results: Those engaging in vigorous physical activity of 3-4 h/week had an effective increase in high density lipoprotein cholesterol (HDL‑C) of 10, more than those who did not do any vigorous physical

activity at all (P = 0.005). There was no additional benefit when exercise was increased to more than 4 h. Those who indulged in regular vigorous physical activity were also more active in other aspects of their day‑to‑day life. Regularly exercising group spent slightly less time being physically inactive during the day. HDL‑C decreased in both groups when they were physically inactive for more than 6 h/day (sleep excluding).

Conclusions: Our study clearly shows that regular exercisers had improved level of HDL‑C. HDL‑C and physical fitness go hand‑in‑hand.
