A high-intensity workout that's not too unpleasant

Short, high-intensity training sessions can produce just as good results as workouts that take an hour - no wonder they're so popular in fitness-land. Most people don't enjoy exercise, so the shorter they have to train, the better. But high-intensity workouts are also extremely unpleasant, and as a result many people give up after a couple of times. American sports scientists may have found a solution.


Most short high-intensit workouts gradually build up intensity, the most intensive exertion only taking place in the last phase of the workout. Zachary Zenko, a sports scientist at Duke University, wondered what would happened if you turn this sequence around.

Zenko got 22 participants to do a traditional, 15-minute high-intensity workout on a bike – a Lode Corival Recumbent [see below] – and another 24 participants to do a workout with a different sequence.

The participants who did the traditional workout had to pedal a little harder each successive minute, until they reached 120 percent of their ventilatory threshold in the last minute. The participants who did the alternative workout started at high intensity, and gradually decreased how hard they pedalled. Both groups completed the same amount of exertion.

During the traditional workout the participants' heart rate increased and the workout became increasingly tiring and more and more unpleasant. The alternative workout had the opposite effect.

The participants reported that they had found the workout pretty pleasant, not only 15 minutes after finishing it, but also a day and a week later too. This was not the case after the traditional workout. At the end of the alternative workout the participants also looked forward to doing more training sessions than those who had done the traditional high-intensity workout.

A high-intensity workout that's not too unpleasant

A workout experience is less unpleasant if the high-intensity elements are done during the first phase of the workout. This type of training is more likely to motivate athletes, and reduce the likelihood of them stopping altogether.

But of course, there are problems... Traditional workout sequences are more unpleasant and less motivating, but they do reduce the chance of injury.

It will be a challenge for trainers and coaches to bring Zenko's insights into practice.
