As Virus Cases Accelerate, Seoul Tells Gym Users to Slow Down


Kang Seung hyun, a teacher and former rugby player preparing for a fitness photo shoot, said the gym chose to turn off the treadmills instead of pushing the slow pace. But the bikes remained open for reasons he didn’t understand.

“So we can’t run or use treadmills, but can we ride bikes? It seems weird to me,” he said.

Ralph Yun, a CrossFit coach who has been teaching classes for the past five months, said that listening to music at a rate similar to your heart rate can improve performance, but that doesn’t necessarily make you work harder.

“You could be listening to slow music and exercising just as intensely,” she said.

Costas Karageorghis, a professor at Brunel University in London who has studied the effects of music on exercise for 30 years, amused by calling the advice “ridiculous.”

“If people are motivated enough to work at a high intensity, music has nothing to stop them,” he said.

However, research has shown that music can significantly alter a person’s training, even if not in the way Korean officials intended.

Dr. The best point for aerobic exercise, such as running on a treadmill or biking, is 120 to 140 beats per minute, Karageorghis said. Music can distract the mind from feeling tired, reduce your perception of how hard the body is working, and improve your mood. Louder music above 75 decibels can intensify a workout, but very loud music poses a risk of hearing problems such as tinnitus.

He said he wasn’t surprised that health officials chose 120 hits, with research suggesting that in some ways it’s a “key cutoff.” A healthy resting heart rate is roughly twice that, and 120 steps per minute is a common walking pace, he said. Wedding DJs said they would use a 120-beat song to lure people onto the dance floor (as Whitney Houston’s “I want to dance with someone” checks in at about 120).
