Table 3. Correlation coefficients (r) between peak fat oxidation (PFO) rate in absolute units (g.min) and relative to fat free mass (FFM) and the following variables: body mass index (BMI), FFM, percent body fat, waist-to-hip ratio, VOmax per kg body mass (mlKgmin) and VOmax per kg FFM (mlKg FFMmin).
