Resting heart rate variability and exercise capacity in Type 1 diabetes

  Figure 1. Plasma catecholamines at baseline and maximal exercise. (A) Epinephrine; (B) Norepinephrine. Baseline (black bars) and maximum exercise (gray bars), in controls (CON; n = 13) and people with Type 1 Diabetes (T1D; n = 15). Values are natural log transformed and are presented as means ± SD.

  Figure 2. Heart Rate Variability indices during baseline and paced breathing. During baseline (black bars) and paced breathing (gray bars), in controls (CON; n = 17) and people with Type 1 Diabetes (T1D; n = 23). (A) TP; Total Power. (B) LF; Low Frequency Power. (C) HF; High Frequency Power. (D) LF/HF ratio; Low Frequency Power to High Frequency Power ratio. Values are natural log transformed (except the LF/HF ratio) and are present as means ± SD.

  Figure 3. Association of Total Power (TP) to maximum aerobic capacity (V̇O2max). In controls (CON; n = 14) and in people with type 1 diabetes (T1D; n = 23). For β‐ and P‐values refer to Table 3. TP was derived from the baseline condition and is non‐transformed.
