Characteristics of the type 2 diabetics individuals (T2D) (n = 9) and non diabetics individuals (ND) (n = 10).
| T2D | ND | |
|---|---|---|
| Age (years) | 55.6 ± 5.7 | 50.8 ± 5.1 |
| Weight (kg) | 83.4 ± 23.6 | 76.2 ± 14.3 |
| Height (cm) | 163.1 ± 10.6 | 169.0 ± 9.2 |
| BMI (kg.m2(-1)) | 30.9 ± 5.2 | 26.5 ± 3.8 |
| Time of disease (years) | 6.0 ± 2.3 | - |
| Fasting blood glucose (mg.dL-1) | 138.6 ± 34.2* | 91.1 ± 5.5 |
| HbA1c (%) | 6.8 ± 1.3* | 5.2 ± 0,4 |
| VO2peak (mL.kg.-1.min-1) | 20.6 ± 4.3* | 29.4 ± 6.8 |
| RMSSDrest (ms) | 21.2 ± 3.5 | 26.3 ± 5.1 |
| SD1rest (ms) | 15.3 ± 2.5 | 20.9 ± 4.6 |
Data expressed as mean (± standard deviation) and standard error of mean for heart rate variability variables (RMSSD and SD1).
BMI = body mass index; VO2peak= peak oxygen uptake; HbA1c= glycated hemoglobin estimated as suggested Rohlfing et al.[21]; RMSSDrest= square root of the mean squared successive differences between adjacent R-R intervals in rest; SD1rest= standard deviation of variability instantaneous beat-to-beat in rest. *p < 0.05 in relationship to ND group.
