comparing beats per minute in music to heart rates of dancers

[Todd's keyboard]

Am looking for any studies that compare the average beats per minute of various styles of dance music to the average heart rates of the dancers.

For example, rock and roll music has a different average bpm than house music. It makes sense that the dancers, matching the beat of the music, would have different heart rates.

I suspect that the popular drugs associated with various styles of dance also influence the heart rates of the dancers. (compare heart rates for a marijuana user to an ecstasy user)

Can anyone refer me to any sources to find out more about this?

thanks, Todd's musico-cardio keyboard
