ABSTRACT
BACKGROUND:
Currently, and to the best of our knowledge, there is no standardized protocol to measure the effect of low- to moderate-intensity physical exercise on autonomic modulation focused in older people.AIM:
Validate a test-retest short-term exercise protocol for measuring the autonomic response through HRV in older people.METHODS:
A test-retest study design was used. The participants were selected through intentional non-probabilistic sampling. A total of 105 older people (male 21.9%; female 78.1%) were recruited from a local community. The assessment protocol evaluated HRV before and immediately after the 2-min step test. It was performed twice on the same day, considering a time of three chronological hours between the two measurements.RESULTS:
The posterior distribution of estimated responses in the Bayesian framework suggests moderate to strong evidence favoring a null effect between measurements. In addition, there was moderate to robust agreement between heart rate variability (HRV) indices and assessments, except for low frequency and very low frequency, which showed weak agreement.CONCLUSIONS:
Our results provide moderate to strong evidence for using HRV to measure cardiac autonomic response to moderate exercise, suggesting that it is sufficiently reliable to show similar results to those shown in this test-retest protocol.Palabras clave
