The purpose of this study was to examine whether the percent body fat was related to the level of physical fitness in Korean men. The subjects were men aged between 19 and 64 years (n = 2,419) who participated National Fitness Award in Korea between May 2012 and October 2012. They were divided into 3 groups: those with <20% body fat, 20?25% body fat, and >25% body fat. The physical fitness tests consisted of grip strength, sit-ups, a progressive aerobic cardiovascular endurance run (PACER), sit-and-reach, shuttle run, and standing long jump. The inter-group differences in physical fitness level were analyzed by one-way analysis of variance with Tukey post-hoc test. The results indicated that compared to the <20% body fat group, the 20-25% body fat group (overweight group) and >25% body fat group (obese group) had a lower fitness level as judged by grip strength, sit-ups, the PACER, sit-and-reach, shuttle run, and standing long jump (p<.05). We concluded that among adult Korean men, fitness level was lower in those with a higher percentage of body fat than in those with lower percentage of body fat.
