Figure 4From: Relation between cardiac dimensions and peak oxygen uptakeLong axis images of the heart in a female control, male control, female triathlete and male triathlete. This figure illustrates the increase in cardiac dimensions with endurance training. Note that the female triathlete (height 1.80 m, weight 70 kg) has a larger heart than the male control subject (1.81 m, 80 kg).Back to article page
