NCT06952673

Brief Summary

In this study, wearable multi-modal microsensors were deployed to simultaneously capture seismocardiography (SCG) and electrocardiography (ECG) signals, delineating the exercise-load-dependent responsiveness of SCG-ECG dynamic coupling during graded-speed treadmill protocols.

Outcome Measures

Primary Outcomes (1)

  • Changes in Seismocardiography (SCG) Signal Amplitude (m/s²)

    Peak-to-peak amplitudes of Seismocardiography (SCG) signals will be measured using a triaxial accelerometer (sampling rate: 500 Hz). The primary parameter assessed is the signal amplitude in meters per second squared (m/s²) per cardiac cycle. Values will be averaged over 30-second artifact-free epochs during rest and exercise stages.

    The entire test will be completed in approximately 90 minutes.

Secondary Outcomes (1)

  • Changes in Electrocardiogram (ECG) R-R Intervals (ms)

    The entire test will be completed in approximately 90 minutes.

Study Arms (1)

Multiple speed increments on a treadmill for healthy individuals

EXPERIMENTAL

Healthy participants will undergo the following experimental protocol: After wearing microsensors and a respiratory/metabolic testing mask, they will rest quietly for 3 minutes, then begin walking at a speed of 3 km/h for 6 minutes, followed by a 3-minute quiet rest period. This will be followed by walking at 4 km/h for 6 minutes and another 3-minute rest. The protocol continues with subsequent stages at progressively increasing speeds of 5 km/h, 6 km/h, 7 km/h, and 8 km/h, each involving 6 minutes of walking followed by 3 minutes of rest.

Behavioral: Multiple speed increments from 3km/h to 8km/h on a treadmill

Interventions

Healthy participants will undergo a fixed experimental protocol of multi-stage treadmill speed walking/running wearing microsensors and a respiratory/metabolic testing mask.
