Factors and Characteristics of Heart Rate Variability in Runners

• Conditions: Heart Rate Variability; Sports Accident
• Interventions: Behavioral: a long-distance running (over 3 km)

• Registration Number: NCT04909788
• Lead Sponsor: Huazhong University of Science and Technology

Brief Summary

The purpose of this study is to describe the variation characteristics and factors of the heart rate variability during long-distance running.

Detailed Description

Heart rate variability is recognized as the indicator to measure the autonomic nerve activity. By monitoring the heart rate variability of runners during long-distance running, we could monitor the status of the runners' cardiovascular system and predict the exercise risk of runners during long-distance running.
