Studies indicate that being overweight per se does not necessarily equate to being metabolically unhealthy. Utilizing a cross sectional design, we are investigating cardiometabolic differences between young men of differing body composition and training status. 9 lean trained (LT, BMI <25 kg/m 2 , 4+ d/wk resistance training) and 15 overweight untrained (OU, BMI>27 kg/m 2 ) subjects were assessed for waist circumference (WC), body composition by DXA, 1‐repetition maximum (1‐RM) strength, physical activity by questionnaire (PAQ), blood pressure, carotid‐femoral pulse wave velocity (cfPWV), augmentation index (AIx), aortic pressure, and sub‐endocardial viability ratio (SEVR). LT subjects had lower WC and trunk/total fat mass (p<0.0001), but no difference in lean body mass (LBM) compared to OU. OU subjects exhibited trends for higher systolic (p=0.10), diastolic (p=0.03) and aortic (p=0.09) pressure, and lower SEVR (p=0.02). No differences in AIx or cfPWV were noted between groups. PAQ confirmed that LT subjects were more physically active than OU subjects (p<0.0001). LT subjects exhibited significantly greater 1‐RM strength for bench press/seated row (p<0.03), but not leg press (p=0.7). These data indicate select phenotypes vary between men exhibiting different body composition and training status. Whether improved metabolic health is dependent on fitness, rather than BMI or LBM requires further study.
