Does resting-state heart rate variability predict EEG oscillatory activity during cycling exercise in senior adults?
Resting-state ECG entropy and EEG activity can predict brain oscillatory activity during cycling in senior adults, suggesting potential markers for identifying those who may benefit most from exercise to reduce frailty.

Resting ECG entropy may identify seniors with stronger brain responses to exercise; hypothesis-generating and should not yet change practice.
EEG, ECG and EMG signals were recorded during 3 stages of cycling exercise in 38 senior adults. Before and after the cycling stages, 5-min resting-state EEG and ECG signals were also recorded in individual subjects. Resting-state EEG oscillatory activity was the best predictor of oscillatory activity during cycling exercise. In addition, resting-state ECG entropy and subjects' weights were also significant predictors of oscillatory activity during cycling exercise especially in the high frequency ranges. Senior females with lower weights and higher resting-state ECG entropy values showed stronger oscillatory activity in all frequency ranges during cycling exercise and weaker oscillatory activity under resting-states compared with other subjects. We conclude that cycling exercise has the potential to reduce frailty in senior adults especially in those who have higher resting-state ECG entropy values.

Liou et al. (2021) conducted an observational in Senior adults (n=38). Resting-state heart rate variability (ECG entropy) was evaluated on EEG oscillatory activity during cycling exercise. Higher resting-state ECG entropy and lower body weight significantly predicted stronger EEG oscillatory activity during cycling exercise in senior adults.
