FIGURE 2. Current exercise training volume and current weight-adjusted VO2max.

FIGURE 2

The relationship between current exercise training volume and current weight-adjusted VO2max is shown. Current exercise training volume is expressed as a percentage of the subject’s training volume prior to pregnancy (%ptp). The equation describing the overall relationship is y = 37.8 + 0.048x, and the r2 is 0.1563. However, if only the linear portion of the relationship is analyzed (current exercise volume between 5% and 100%), the r2 is 0.3522.
