When Europeans and Americans saw celebrities such as supermodels and Hollywood stars under the guidance of personal fitness coaches, they readily accepted the "jogging" movement that became an instant hit at 1980 and followed suit. However, after carefully observing the jogging process of these celebrities, they were surprised to find that jogging today is not what it used to be, and there are many articles in it.

This new fitness trend, which is about to surge, has a strange name, Tolek. The word comes from Sweden, which means "the game of speed", that is, the running form that changes the terrain and speed as much as possible when running. This running style was created by Olympic coach Gerst Homer 50 years ago. At that time, the original intention was to integrate "fun" into athletes' strict training courses, so that they would not feel bitter in extremely hard sports.

This fast and slow running method allows runners to start from the natural landscape, set their own starting point and finishing point, and run a round at alternating speeds.

"The charm of this kind of jogging is that you don't have to follow an orderly set of rules or dogmas. You can adjust the speed or difficulty according to your ability." Anderson, a former British Olympic athlete and current running coach, said: "If you are an ordinary jogger, fix it for 20 minutes every day. If fartlek can be integrated into it, not only running will be much more interesting, but also more fitness effects can be obtained. This is not easy to do, so it is not suitable for running every day. You might as well run 1-2 times a week first, and you will feel different. "

People who take aesthetic health as their concept are eager for this new way of running. Because research shows that this kind of mixed intensity running is easier to lose weight than slow and steady running.

Mark mark simpson, a sports physiologist at the Institute of Sports Science of Robreau University, thinks: "If you always keep a moderate pace of exercise, your body will adapt and your metabolism will gradually slow down over time. If you use Tolek to increase the intensity of exercise 15 minutes, your body's metabolic rate will increase significantly and last for a long time. In this way, spontaneous combustion burns more heat and quickly achieves fitness goals. "

In Norway, researchers found that a jogger who kept jogging for 70 minutes was still burning fat quickly within 15 hours after running. However, those joggers who adopt a steady pace cannot achieve this effect.

Scientific tests have also proved that people who often run fartlek have increased the activity of enzymes that promote fat decomposition in their muscles, so they can consume more body fat.

How to convert a 20-minute jog into a Tolek run? Pedro Glass, a running coach in Tolek, USA, suggested:

1, be sure to jog for 5 minutes to warm up, and then start 10- 15 minutes of Fatlake running.

2. Try to run in rugged woodlands, so as to exercise the muscles of all parts.

3. According to your physical strength, change your pace at any time, or make a full-speed sprint between telephone poles.

4. Be sure to jog for a while after each quick run to make your body fully recover.
