In a study published in the European Journal of Applied Physiology, researchers concluded that a 6 week program of both moderate (10 s work : 20 s rest) and heavy (30 s work : 60 s rest) intensity interval training…

  • Reduced Carotid Arterial Stiffness in both groups
  • Improved Heart Rate Dynamics in both groups
