Do NOT Stop Abruptly after Race - High Risk of Arrhythmia and Vasovagal Syncope

Expert: Dr. Gary Mak - Specialist in cardiology and President of the Hong Kong Association of Sports Medicine and Sports Science

Key Points:

  • DON’T stop abruptly after running; a long and slow cool-down period is important.
  • Abrupt stopping will put the heart under high stress as it will aggravate the imbalance between sympathetic nervous system and parasympathetic system, which are responsible for the exercise and cool-down of our bodies. Abrupt stopping might trigger either one of the following situations:

  1. Sympathetic nervous system, which functions to increase heart rate to support the body for exercise, might become persistently hyperactivity and causes arrhythmia or even sudden death.
  2. Parasympathetic system, which functions to restore normal heart rate after exercise, might act too quickly and causes low blood pressure and slow heart rate which in turn triggers vasovagal syncope.
