Abstract
Introduction: VO2max is the maximum capacity to transport & utilize O2 during incremental exercise and VO2max is the accepted measure of cardiorespiratory effiency. VO2max in normal active male is 38ml/kg/min and in normal active female is 29ml/kg/min. Previous studies shows significant lower values of mean VO2max/kg/min in obese people.
Aims & Objective: To compare VO2max during tread mill exercise in young healthy adult male in relation to BMI.
Materials and Methods: in the present study 50 healthy young adult male were selected of 18-25 yrs of age. The BMI of the subjects were then measured and their VO2max were calculated before and after 9 mins of treadmill exercise. The formula used to calculate VO2max is VO2max=111.33-(0.42x HR in bpm). RESULT: 50 medical students were selected and they gone through 9 min tread mill test during which heart rate and their VO2max were calculated and then compare with their BMI, which shows a significant negative relationship, with increase in BMI there is decrease in VO2max/kg.
Conclusion: The present study shows that with increase in BMI there is decrease in VO2max/kg, which signifies that increase in BMI leads to decrease in cardiorespiratory fitness.
Abbreviations: HR heart rate, BMI body mass index.
