Table 3.
Heart rate kinetics during recovery from 6MWT in older adults with and without ID.
| Variables | Non-ID group (n=24) | ID group (n=24) | p |
|---|---|---|---|
| Mean (SD) | Mean (SD) | ||
| Heart Rate Kinetics – t-off | |||
| a (bpm) | 17(6) | 20(7) | 0.152 |
| TD (s) | 6(5) | 15(11) | 0.001 |
| τ (s) | 19(10) | 35(17) | 0.001 |
| MRT (s) | 25(9) | 50(11) | <0.001 |
Values are means (standard deviation). ID, intellectual disability; a, heart rate amplitude; TD, time delay; τ, time constant; and MRT, mean response time. Statistically significant values are showed in bold (p≤0.05).
