What is Interval Training?

When fitness experts look at the word interval in terms of training we’re defining it as a period of intervening time.  Interval Training consists of short bursts of high intensity exercise. The overall goal of interval training is more often to improve aerobic and anaerobic energy metabolism. Aerobic interval training consists of slightly lower intensity bursts of energy than that of anaerobic interval training. Also, aerobic intervals are slightly longer.

There are 2 energy systems that can be targeted with anaerobic training:  the ATP-CP system, which can be improved by higher intensity and short bursts of energy, while slightly longer intervals are supposed to improve the Lactic Acid system. A period of rest following the bursts of energy allows for individuals to maintain the high intensity level of activity.

Why does interval training work and why should we improve our energy systems?

For athletes, marathon runners, tri-athletes, soccer players, or basically any fit individuals wanting to improve performance, this type of training is important because it specifically improves the cardio-respiratory system’s capability to perform high intensity exercise at a longer duration before producing lactic acid. Lactic acid is a by-product that the body produces which slows us down. Most athletes want to perform to their best ability for as long as possible, hence the longer they can go without being slowed down by lactic acid, the better their performance capability.

Who should do interval training?

It is important for individuals to have a strong aerobic base before doing interval training. Individuals should already be at a level that is above beginner and their bodies are capable of using oxygen efficiently. Interval training has been popularized and predominantly used by athletes, but athletes are not the only people who can benefit from interval training.

Often you hear of people hitting a “plateau,” meaning on the journey to their fitness goals they’ve come to a standstill. Interval training is a higher intensity method of physical activity.

It can be incorporated into a program to assist those who need to lose the last 10 pounds, or improve muscular power to increase workout intensity.

What are the risks?

Interval training often consists of plyometric exercises and these exercises can be hard on the body. Those with any knee or joint issues are not advised to perform such high impact activity. Also, because the body is required to take in oxygen and use it efficiently, asthmatics and those with any heart conditions would usually be advised to not perform this high intensity training. Always consult a physician before considering any type of training or classes. But for those who want to burn a ton of calories, kick-start their metabolism and see an improvement in their performance, muscular power and physique, interval training is a great activity to target those goals.
