High-Intensity Interval Training
What are the benefits of HIIT?
- aerobic and anaerobic fitness
- blood pressure
- cardiovascular health
- insulin sensitivity (which helps the exercising muscles more readily use glucose for fuel to make energy)
- cholesterol profiles
- abdominal fat and body weight while maintaining muscle mass
Why is HIIT training so popular?
How do you develop a HIIT exercise program?
The relationship of the work and recovery interval is important. Many studies use a specific ratio of exercise to recovery to improve the different energy systems of the body. For example, a ratio of 1:1 might be a 3-minute hard work (or high intensity) bout followed by a 3-minute recovery (or low intensity) bout. These 1:1 interval workouts often range about 3, 4, or 5 minutes followed by an equal time in recovery. Another popular HIIT training protocol is called the “spring interval training method”. With this type of program the exerciser does about 30 seconds of ‘sprint or near full-out effort’, which is followed by 4 to 4.5 minutes of recovery. This combination of exercise can be repeated 3 to 5 times. These higher intensity work efforts are typically shorter bouts (30 seconds with sprint interval training).
What are the safety concerns with HIIT training?
Regardless of age, gender and fitness level, one of the keys to safe participation of HIIT training is for all people to modify the intensity of the work interval to a preferred challenging level. Safety in participation should always be primary priority, and people should focus more on finding their own optimal training intensities as opposed to keeping up with other persons.
