Improve Cardiovascular Endurance Through HIIT Exercise

Updated: May 2, 2019


  • HIIT has started to become more popular comporting with MIT, moderate intensity training.

  • In a study performed on rat where the population is separate into 3 groups; one group train at moderate intensity, the other at high in tensity interval for 13 weeks and a control group which kept sedentary. At the end of the study, result show high intensity interval group show significant increase in capillary density and overall cardiac function. (1)

  • A HIIT session typically lasts 30 min or less and can consist of a variety of exercises as long as your heart rate stays elevated, which is the goal.

  • An example of a HIIT session is sprints. For example, they can be done in 30-45 second bouts with 1 minute in between for rest. The participant would continue this for at least for 10 minutes.

  • In one study that was conducted in rats it was found that HIIT could increase cardiovascular fitness. While HIIT is a helpful tool while training an in experienced athlete may not want to push too hard in order to avoid injury.

  • HIIT can be helpful in training to switch up a routine, push one's limits, and improve one’s cardiovascular fitness.
