Supports reliability of active-walking HRV measures in athletes; leaves open clinical adoption pending larger prospective validation.
Observational (n=12)
Are heart rate variability and recovery measures reliable during active walking before and after maximal running efforts in endurance athletes?
Heart rate variability and recovery measures during active walking are reliable tools for assessing autonomic control before and after maximal exercise.
Boullosa et al. (2014) conducted an observational in Healthy (endurance athletes) (n=12). Active walking (4 km/h) before and after a maximal running test was evaluated on Absolute (CV) and relative (ICC) reliability of time domain and non-linear measures of HRV and HRR parameters. Heart rate variability and recovery measures during active walking before and after maximal running efforts demonstrated moderate to very high reliability (ICC 0.73-0.97).
