Improve your endurance with polarized training

Improve your endurance with polarized training

There are three things you always have to keep in mind when doing endurance training: The training duration, the training frequency, and the training intensity. Due to new findings, the control of the training intensity plays a particularly important role. It is the most effective way to improve performance and is especially true for polarized training, where you train either very hard or very slowly.

The new formula for success in training

For decades there was only one training approach to improve endurance performance: Purely aerobic training units laid the foundation for increasingly intensive and faster training programs. There was a reason for this: if you want to run a high pace over a longer distance, you need to be able to remove lactate from the working muscles. Because if the lactate exceeds specific values, it starts to hurt, and you are forced to reduce your speed. Training at the aerobic-anaerobic threshold should improve the ability to remove lactate from the muscle. The technical term for this is lactate tolerance. The training itself is called lactate threshold training.

Lactate threshold training is still trendy

The lactate threshold training also works. It improves endurance performance. It is especially true for beginners. Evaluations show that the majority of internationally successful runners, rowers, and cyclists, too, do 75 to 80 percent of their training in the purely aerobic area. About ten percent of training takes place in the lactate threshold range. But now the new studies show that there may be a more effective training method. Especially athletes and competitive athletes who are already well-trained benefit from polarized training. The latest recommendations are now:

  • You should still do most of your training in aerobic exercise. The order of magnitude is 80 percent.
  • 20 percent of training should be at a very high or maximum intensity.
  • Lactate threshold training is considered unnecessary and can be omitted.

A few practical tips

If you do six sessions a week, you should do two of them at high intensity. The total exposure time is then two to two and a half hours. Four units with an entire duration of ten hours are tranquil. Necessary: Experts recommend polarized training all year round.

The latest study results

Scottish scientists have studied two groups of well-trained cyclists. Both groups completed two six-week training blocks. The volume was the same for both groups. One group trained according to the 80 – 0 – 20 model. In other words: 80 percent purely aerobic training and 20 percent high-intensity training. The other group did threshold training according to the 60 – 40 – 0 model. In other words, 60 percent aerobic, 40 percent lactate threshold training, and no high-intensity training.

  • Before and after each training period, the athletes were closely examined.
  • Muscle biopsies were taken, and the so-called mitochondrial enzyme activity was determined.
  • Besides, the cyclists had to pass several performance tests. These included a 40-kilometer time trial and the duration of the ride at 95 percent of maximum performance.

Polarized training shows an enormous success

The results: In all test persons there were training adaptations in the muscles, in endurance performance and with regard to the lactate threshold. They were also able to tolerate higher training loads. However, the performance gains of the 80 – 0 – 20 model were up to 10 percent higher in all areas. A Chinese study with speed skaters came to similar results. What’s more, scientific research published a few weeks ago went to another exciting result in track and triathletes. Lactate threshold training brings less speed increase compared to periodized training. And that can decide on victory or defeat in the last few meters.

My author colleague Professor Billy Sperlich from the University of Würzburg – we wrote a popular running guide together – was also able to prove in a nine-week study with 48 test persons that polarized training is more effective than threshold training.

Not suitable for beginners

Finally, a note: polarized training is not suitable for beginners at first. You should first build up an individual base. And even those who are already well trained should be healthy. The 80 – 0 – 20 – method is an extreme strain for the body.
