Background: Central obesity has been established to be linked with increased cardiometabolic health risks. Waist circumference (WC), conicity index (CI), and A Body Shape Index (ABSI) are anthropometric proxy for central obesity. Maximal aerobic capacity (V̇O2max) provides an estimation of cardiorespiratory fitness of an individual. Decrease in V̇O2maxhas also been established to be associated with increased health risk. Aim: The aim of the study was to find out correlation between central obesity parameters and V̇O2max. Materials and Methods: A cross-sectional study was conducted with 154 young adults (male = 90 and female = 64) who were in daily exercise. WC, height, and weight were measured to calculate CI and ABSI according to formulae. V̇O2maxwas estimated by submaximal exercise test – 1.5 mile run test. Pearson's correlation coefficient was used to find out correlation between central obesity parameters and V̇O2max. Results: Mean age of male and female was 21.89 ± 3.65 years and 21.06 ± 2.92 years, respectively. Correlation coefficient between WC and V̇O2maxwas r = −0.61 (P < 0.001), ABSI and V̇O2maxwas r = −0.46 (P < 0.001), and CI and V̇O2maxwas r = −0.59 (P < 0.001). Conclusion: Central obesity anthropometric parameters were negatively associated with V̇O2max. WC showed higher negative correlation with V̇O2maxthan CI and ABSI. Hence, CI and ABSI are not better predictor variable in comparison with simple WC for V̇O2max. Further studies are needed to explore this association for general population.
