Figure 3.

Workload compared to the Borg scale. The figure shows a significant increase in workload after 3 and 15 weeks (P = 0.007 and P = 0.008). The Borg scale remained unchanged (P = 0.171 and P = 0.105, respectively) although significantly higher workloads and higher heart rates during exercise were attained. Values are indicated as the mean, and the bars represent standard deviation. The columns represent workload (measured in Watt) and the dotted line the Borg Scale.
