Each enrolled subjects BMI was recorded and evaluation of Physical Fitness Test was done by 40mm Endurance test, VO2 max and physical fitness indexResult: There was significant difference in Physical Fitness parameters values between obese and non obese students, indicative of decreased physical activity in obese. This indicates implementation of early interventional programs (weight reduction, life style changes and physical exercise) to prevent obesity related cardiovascular sequelae in future.
