case_images: Before and after each period, we performed a graded cardiopulmonary exercise test (CET) on a stationary bicycle in order to assess her physical fitness and the training effects on cardiac regulation (Figure 1). As indicated in Figure 1, CT for 6 weeks did not affect the resting HR in our patient (mean HR: 121) in comparison to baseline (mean HR: 121).

case_images: Figure 2 illustrates HRs during the CET at baseline, after CT, after IT, and after 6 weeks of detraining.
case_images: Root mean of squared successive difference - RMSSD, instantaneous variability - SD1, and SD1 normalized by mean RR - SD1/RRMean are shown for the patient before training (baseline) after 6 weeks of continuous training, 6 weeks of interval training, and 6 weeks of detraining.

case_images: CT to increase HRV. Changes of HRV measures such as RMSSD, SD1, and SD1/RRMean are depicted in Figure 3. All HRV measures returned to baseline levels within 6 weeks after detraining (Figure 3).
case_images: Peak oxygen uptake (VO2peak) and oxygen uptake at the ventilatory threshold 1 (VT1) before training (baseline), after 6 weeks of continuous training, 6 weeks of interval training, and 6 weeks of detraining.

case_images: As displayed in Figure 4, we did not observe a change of VT1 after CT when comparing baseline and fitness after training (-1%).
