Running doesn’t have to be all about logging as many miles as possible. More and more people are discovering the real benefits of interval training and are making the switch from running far to running fast. And the best news? Interval training is much more effective on many levels than simple distance running. And this is the reason why Freeletics Running is based on interval workouts. More effective and motivating running, more results. But what is the science behind intervals? Why are they more effective than long-distance runs? And who can try interval running?
What is interval running?
Interval training doesn’t necessarily mean running at highest or even high intensity. It simply describes a sequence of predefined distances or lengths of time to be run, broken up by recovery breaks in between. Depending on the goal and speed of the intervals, the breaks will either be used to recover or to continue running but at a slower pace.
Professional runners have long been using interval running to bring their performance up to the next level. Athletes who want to be able to run fast over distances need to run faster in their training. In the long run, interval running helps you to run at a higher speed than would usually be possible during distance runs. For those Athletes preparing for races and running events, intervals will be run at the pace they wish to run at on the day.
Why is interval running so effective?
Faster weight loss
This type of running doesn’t just increase performance and speed, and is definitely not just for racers or professionals. It also boosts weight loss – when done properly, running intervals can burn up to three times as many calories than a comfortable distance run, even if the total time spent running is the same. Because of the fast segments, the body is burning more energy, as it now has to move the same mass but at a higher speed. Also, the fast-twitch muscle fibers come into play during the short, fast sprints. These burn a higher amount of energy than the other muscle fibers because they work explosively and use a large amount of energy whilst doing it. This also means that they cannot keep up the work for very long before they need to recover and more energy needs to be collected for the next round.
If that wasn’t enough, interval training also triggers the famous afterburn effect, which is very much higher after intensive interval runs than after a normal distance run. The afterburn effect after a comfortable distance run is usually almost zero, but after an intense interval workout like the ones in Freeletics Running, it can hold for up to 48 hours after training has been completed. This means that the body is still working on (and benefitting from) the training up to two days later.
The body adapts quickly and will get used to continuous stress in the form of training, such as distance running. This means that the effect will become less and less prominent with time. Without variety and new challenges, the body will reach a plateau in its progress and performance. To enhance the cardiovascular system and metabolism, there have to be new challenges incorporated into training. And interval running is the perfect way to achieve this. Fast intervals enhance the body’s maximum oxygen absorption, oxygen transportation (heart), oxygen capacity (lungs), and oxygen utilization (cells). Also, the metabolism is optimized and energy used more efficiently within the body. Combined, this will increase the performance of your body drastically, allowing you to run faster and further for longer.
Who can begin with interval running?
Anyone can run intervals – they are the ideal way to get into running. But it is the intensity which is key. Especially beginners or overweight individuals should be sure to first get used to running and build up a basic level of endurance before taking on fast intervals. Some people stop running quickly after starting because of common injuries amongst beginners caused by too much training too soon, or because they find distance runs boring. So intervals mixed with walking breaks are ideal to combat both of these problems. Even if running 3k in one go is too much for a beginner, running and walking alternately for 6k is usually possible. This type of running is also perfect for running with friends, as there is plenty of time for talking, so beginners don’t have to go it alone from the start if they don’t feel comfortable doing so.
When the right intensity is chosen, interval running is ideal for any performance level – even beginners. Interval training can be tailored to any individual and their goals and needs, which is exactly what the Running Coach does. It is the most effective way to run and will get you to your goals faster, helping you to enjoy running more along the way.
