The metabolically healthy obese (MHO) characterized by the absence of abdominal obesity have been reported to have superior cardiorespiratory fitness (CRF) than the metabolically unhealthy obese (MUO). However, this finding might be biased by the baseline sedentary behavior in the general population.This study utilized 3,669 physically active military males aged 18-50 years in Taiwan. Obesity and metabolically unhealthy were respectively defined as body mass index ≥27.5 kg/m2 and waist circumference ≥90 cm, specifically for Asian male adults. Four groups were accordingly classified as the metabolically healthy lean (MHL, n=2,607), metabolically unhealthy lean (MUL, n=234), MHO (n=208) and MUO (n=620). CRF was evaluated by time for a 3-kilometer run, and muscular strengths were separately assessed by numbers of push-up and sit-up within 2 minutes. Analysis of covariance was utilized to compare the difference in each exercise performance between groups adjusting for age, service specialty, smoking, alcohol intake, and physical activity.The prevalence of metabolic syndrome in MUO, MHO, MUL and MHL was 45.3% 13.0%, 29.1% and 3.7%, respectively. The performance of CRF did not differ between MHO and MUO (895.3±5.1 sec and 891.5±3.1 sec, p=0.68) which were both inferior to MUL and MHL (877.5±4.8 sec and 849.5±1.4 sec, all p-values |
