Circadian variation in the circulatory responses to exercise: relevance to the morning peaks in strokes and cardiac events

  title={Circadian variation in the circulatory responses to exercise: relevance to the morning peaks in strokes and cardiac events},

Sudden cardiac and cerebral events are most common in the morning. A fundamental question is whether these events are triggered by the increase in physical activity after waking, and/or a result of circadian variation in the responses of circulatory function to exercise. Although signaling pathways from the master circadian clock in the suprachiasmatic nuclei to sites of circulatory control are not yet understood, it is known that cerebral blood flow, autoregulation and cerebrovascular… CONTINUE READING
