Objectives: Physical fitness is defined as ‘the ability to carry out daily tasks without undue fatigue’, and essentially depends on cardiorespiratory fitness. This can be assessed by measuring aerobic capacity of a person- indicated by Maximum oxygen capacity (VO2 max), which is the maximum volume of oxygen that the body processes during intense exercise. Factors that determine VO2max include age, gender, heart and lung function, aerobic muscle metabolism, exercise, genetics and nutritional status such as BMI, abdominal circumference, and percent body fat.This study assesses the correlation between anthropometric parameter of Waist-Hip-Ratio (WHR) and VO2max in young healthy subjects.Methodology: 50 young adults (between 18-21 years) were randomly selected and health status assessed from history and clinical examination. After obtaining written, informed consent, anthropometric parameters like height, weight, waist and hip circumference were measured using standard procedure. The estimated VO2max was measured with the Queen’s College step test (QCT), using the post-exercise heart rate. Results: Among the 25 males and 25 females studied, the mean WHR was 0.87±0.03 in males and 0.79±0.03 in females. The mean VO2max was 42.69±0.94 mL/kg/min in males and 36.93±1.56 mL/kg/min in females. The findings showed significant negative correlation between WHR and VO2max (-0.651).Conclusion: The greater the waist-hip-ratio, the lower the level of cardiorespiratory fitness. The presence of more fat tissue is not only as a place to store triglycerides, but is also a producer of bio- active substances called adipokines, namely leptin, which can affect the cardiovascular system and increase the risk of metabolic syndrome and insulin resistance, the development of which is strongly related to the accumulation of upper body fat than lower body fat in both sexes.
