Figure 1. Relationship between skeletal muscle mass (SMM) and absolute VOmax in sumo wrestlers (filled circles), untrained controls (unfilled circles), and combat (filled squares), aerobic (unfilled diamonds), and power sport athletes (filled diamonds). Equation and correlation results: aerobic athletes, y = 0.0416x + 3.8116, R = 0.70, power athletes, y = 0.0885x + 0.4407, R = 0.69, sumo wrestlers, y = 0.0078x + 3.2051, R = 0.14, untrained controls, y = 0.1022x + 0.6564, R = 0.70, combat athletes, y = 0.089x + 1.3745, R = 0.88. Sources: sumo wrestlers and untrained controls, current study; all others from previous results listed in Table 1 and grouped as listed in Methods.
