Peak oxygen uptake (VO2peak) is commonly indexed by total body weight (TBW) to determine cardiopulmonary fitness (CPF). This approach may lead misinterpretation, particularly in obese subjects. We investigated the normalization of VO2peak different composition markers. analyzed combined data 3848 subjects (1914 women; 49.7%), aged 20-90, from two independent cohorts population-based Study Health Pomerania (SHIP-2 and SHIP-TREND). was assessed exercise testing. Body cell mass (BCM), fat-free (FFM), fat (FM) were determined bioelectrical impedance analysis. The suitability markers as a variable evaluated taking into account correlation coefficients (r) intercept (α-coefficient) values linear regression models. A combination high r low α considered preferable for purposes. BCM best (r = .72; P ≤ .001; α-coefficient 63.3 mL/min; 95% confidence interval [CI]: 3.48-123) followed FFM .63; 19.6 CI: -57.9-97.0). On other hand, much weaker markedly higher found TBW .42; 579 483 675). Likewise, FM also identified poor .10; 2133; 2074-2191). Sex-stratified analyses confirmed above order variables. Our results suggest that BCM, FFM, might be most appropriate marker when comparing CPF between with shape.
