Abstract
This study investigated cardiac-locomotion synchronization (CLS) during indoor treadmill and outdoor free walking, examining its environmental differences and relationships with heart rate/gait rhythm variability. Twelve participants used wearable ECG and accelerometer sensors for data collection during self-paced brisk walking. We analysed the last 10 minutes of stable walking, calculating mean period, coefficient of variation, and detrended fluctuation analysis (DFA) slope α. CLS was quantified by the 'Sync rate', the temporal proportion of consistent gait cycle to R-R interval ratios. Results showed significantly higher Sync rates in outdoor walking. Outdoor gait rhythm fluctuation α tended to decrease with increased Sync rate. These findings suggest CLS occurrence without treadmills, relevant to physical therapy.
