Abstract: Method: The investigator obtained ethical clearance from institution and permission from school authorities and carried out an observational study amongst 105 high school students of R.V Educational Institutions, Bengaluru through convenient sampling. A written signed informed consent from the parent/legal guardian and a written signed informed assent from the student were taken. The investigator screened the subjects in the selected class for meeting the requirements of inclusion and exclusion criteria. Data was collected using self-administered Physical Activity Questionnaire for adolescents (PAQ A), Body Mass Index (BMI) and 20m shuttle run test. Results: 105 high school students participated in the study out of which 37.14% (n=39) were males and 62.85% (n=66) were females, with the mean age of 14.11 ± 0.80years. 43.80% (n=46) of the population were underweight, out of which 20% (n=21) were males and 23.8% (n=25) were females.6.6% (n=7) were overweight, out of which 2.85% (n=3) were males and 3.8% (n=4) were females. 99.04% of the population were found to be moderately physically active. Mean cardiorespiratory fitness assessment by measuring VO2 max was 36.21±6.15ml/kg/min,13.3% (n=14) had very poor cardiorespiratory fitness and all of them were males, 48.57% (n=51) had fair cardiorespiratory fitness out of which 12.38% (n=13) and 36.19% (n=38) were males and females respectively,9.52% (n=10) had excellent cardiorespiratory fitness and out of which 4.76% (n=5) were males.1.9% (n=2) had superior cardiorespiratory fitness and all of them were females. Conclusion: In the studied population prevalence of obesity is null but overweight is seen, most of the children were underweight and most are moderately physically active and have fair cardiorespiratory fitness levels. Hence focus should be on maintaining overweight children under normal BMI and nourishment to the underweight children. Programmes to stimulate physical activity and to improve cardiorespiratory fitness should be initiated.
