A new study published shows the benefits of high-intensity intervals for increasing cardiovascular fitness over other forms of exercise.
The study shows that by increasing the intensity of your exercise, you can beat back the risk of metabolic syndrome, the troublesome set of risk factors that can predispose people to type 2 diabetes, stroke and cardiovascular problems.
When the Jebsen Center researchers looked at the importance of the intensity of exercise versus the duration, intensity was far more important than duration in determining peak oxygen uptake.
They have also looked at the benefits of high intensity exercise in the form of interval training — where four or more short periods (typically 4 minutes) of very high intensity exercise are followed by a similar number of short periods of lower intensity exercise. This approach, called 4×4 interval training, is a quick way to increase your overall fitness, research from the Jebsen Center has confirmed.
