Washington: Music not only makes us feel relaxed but offers other benefits as well. A recent study has suggested that upbeat music can make a rigorous workout appear less difficult. The study was published in the journal 'Psychology of Sports and Exercise'.
"While HIIT is time-efficient and can elicit meaningful health benefits among adults who are insufficiently active, one major drawback is that people may find it to be unpleasant. As a result, this has the potential to discourage continued participation," said Matthew Stork, a postdoctoral fellow in the School of Health and Exercise Sciences.
Previous research led by Stork and UBC Okanagan's Kathleen Martin Ginis has examined the effects of music during HIIT with recreationally-active people. Their recent study tested the effects of music with participants who were insufficiently-active, used a more rigorous music selection process and implemented a HIIT regimen that is more practical for less-active adults. First, stork gathered a panel of British adults to rate the motivational qualities of 16 fast-tempo songs. The three songs with the highest motivational ratings were used for the study.
"Music is typically used as a dissociative strategy. This means that it can draw your attention away from the body's physiological responses to exercise such as increased heart rate or sore muscles. "But with high-intensity exercise, it seems that music is most effective when it has a fast tempo and is highly motivational," said Stork.
Next, a separate group of 24 participants completed what has been referred to as the 'one-minute workout' – three 20-second all-out sprints, totalling 60 seconds of hard work. A short rest separated the sprints, for a total exercise period of 10 minutes including a warm-up and cool-down. Participants completed these HIIT sessions under three different conditions – with motivational music, no audio or a podcast that was devoid of music.
Participants reported greater enjoyment of HIIT. They also exhibited elevated heart rates and peak power in the session with music compared to the no-audio and podcast sessions. "The more I look into this, the more I am surprised. We believed that motivational music would help people enjoy exercise more, but we were surprised about the elevated heart rate. That was a novel finding," he said.
Stork believes the elevated heart rates may be explained by a phenomenon called 'entrainment.' "Humans have an innate tendency to alter the frequency of their biological rhythms toward that of musical rhythms. In this case, fast-tempo music may have increased people's heart rate during the exercise. It's incredible how powerful music can be," he added.
Stork's research indicates that for people who are deemed insufficiently active, music can not only help them work harder physically during HIIT but it can also help them enjoy HIIT more. And because motivational music has the power to enhance people's HIIT workouts, it may ultimately give people an extra boost to try HIIT again in the future.
