Brief, Intense Exercise May Appeal to Inactive People

High-intensity interval training (HIIT), which consists of multiple short bouts of intense exercise, is time-efficient and good for your health.

But would inactive people be interested in such an intense type of exercise?

There is very little research on how inactive people perceive HIIT, said researcher Matthew Stork, a Ph.D. candidate at the University of British Columbia (UBC).

“The number one cited barrier to physical activity is a perceived lack of time, and research has shown that as little as 10 minutes of HIIT, three times per week can elicit meaningful health benefits,”¬† Stork said.

“The concern is that short bursts of intense exercise may be perceived as unpleasant, especially for those who aren’t physically active to begin with.”

In the new study, Stork compared inactive people’s feelings and enjoyment of HIIT to traditional long-duration aerobic exercise. Specifically, Stork wanted to know how non-exercisers felt about their high intensity exercise experience both during and after their sessions.

He also hoped to determine whether feelings, ranging from pleasure to displeasure, during a HIIT session could predict the likelihood of participants completing the same exercise on their own time, outside of the lab.

His findings, recently published in the journal Medicine & Science in Sports & Exercise, reveal that inactive people who tried the high intensity exercise for the first time found it just as enjoyable as traditional exercise.

“We wanted to learn more about people’s perceptions towards HIIT and ultimately determine if even inactive people are willing to do these types of exercises on their own free time,” said Stork.

“There’s research evidence showing that negative feelings experienced during traditional forms of exercise, like going for a long run, can lower your likelihood of completing that exercise again in the future. We anticipated the same would be true for HIIT, but as it turns out, it’s not so simple.”

Stork and his team recruited 30 inactive men and women who had never tried HIIT before. Each participant completed high intensity and traditional moderate intensity exercise on a stationary bike in the lab.

The researchers tracked how the participants felt on a multi-point pleasure-displeasure scale throughout the exercise. Each participant was also asked to log any exercise they completed on their own during the following four weeks.

“We found that participants reported equal levels of enjoyment and preferences for HIIT in comparison to traditional exercise, despite experiencing feelings of displeasure during the higher intensity exercise,” said Stork.

“Importantly, 79 per cent of participants reported completing HIIT on their own, outside of the lab.”

Stork says his study should give hope to those who struggle to fit exercise into their busy lives.

“Many people want to give up on exercise because they don’t feel that they have enough time. However, HIIT may be a viable, time-efficient exercise option, even for inactive people who have never tried it before.”
