Poincare plot analysis of ultra-short-term heart rate variability during recovery from exercise in physically active men

摘要

BACKGROUND: Recently there has been increasing interest in the study of ultra-short-term heart rate variability (HRV) in sports performance and exercise physiology. In order to improve standardization of this specific analysis, we evaluated the ultra-short-term HRV analysis through SD1Poincare Index to identify exercise induced responses.
