Background: Physical exercise contributes to maintaining good health as it can prevent various chronic diseases like hypertension, diabetes mellitus, cancer, obesity, cardiovascular diseases, and bone and joint diseases including osteoporosis. Objective: To estimate the routine biochemical parameters after moderate physical exercise in healthy premenopausal female volunteers and to compare these parameters before exercise and after exercise. Methods: Thirty premenopausal female volunteers without any menstrual irregularities in the age group 20-50 years were included. They performed walking for 30 minutes and blood samples were collected 15 minutes before exercise, 1 hour after exercise and 24 hours after exercise. Routine biochemical parameters were done and compared before and after exercise. Female volunteers with menstrual disorders, history of medication, and chronic diseases such as hyper/hypothyroidism, diabetes mellitus, hypertension, and respiratory diseases were excluded from the study. Result: Significant decrease was found in levels of blood glucose, serum sodium and potassium, although they remained within the normal range. The alterations in other routine parameters like serum urea, uric acid, LDL and total cholesterol were insignificant. Conclusion: The present study showed that moderate physical activity has a significant effect on selected biochemical parameters like blood glucose and serum electrolytes.
