Japanese Study Suggests Listening to Music May Temporarily Lower Testosterone Levels
Many athletes like to train with music on their ears. However this research done by Hajime Fukui, a Japanese endocronologist might surprise you.
Back in 2001 Fukui did an experiement with 70 students aged between 19-25 (both men and women), at the Nara University of Education.
He took saliva samples from the students before the test, and then divided the students into groups that would listen various types of music for 30 minutes:
10 of the students listened their favorite music
10 listened to Cantatas by Gregorian monks
10 listened to hit music that was popular at the time
10 listened to Mozart’s Sonata in D Major, K. 448
10 listened to jazz music
20 didn’t listen any music at all
After the 30 minutes had passed, Fukui again measured the subjects saliva testosterone levels.
The results were extremely surprising…
…As Fukui found out that listening to all types of music increased saliva testosterone levels in women, but significantly decreased them in male subjects.
The image below shows how the male volunteers reacted to various music styles:
Fukui himself says that humans invited music to make working in groups easier. Testosterone on the other hand is a hormone linked to aggression and more or less continous sex drive, which obviously makes working in groups harder. That’s why Fukui believes that music triggers an evolutionary mechanism in the male brain to decrease the levels of testosterone when we hear music.
That’s a food for tough, but at least now we know that music during a workout isn’t beneficial at all.
As you can see from the graph above, the music that did most damage was the subjects favorite kind, and the one that did the least damage was the music sung by Gregorian monks. So if you want to listen to music with the least amount of damage to your hormones, go for Gregorian (who in the world would listen to this in a gym).
