The only problem I have with this experiment is that there is no control for muscle memory.
If you compared the metabolic rate of a piano player playing piano vs. someone who's never touched one before, intuitively the skilled player would outperform the unskilled player. (There are certainly better examples.)
How much experience arm-swinging did those in the arm-swinging group have?
How much experience opposite-swinging did those in the opposite-swinging group have?
How much experience keeping their arms still while walking did those in the still-armed group have?

- jpwagner 17y agoI think you misunderstand. Imagine I wanted to see which arm is better for throwing a ball: right or left. I choose 1000 subjects and ask 500 of them to throw lefty and 500 to throw righty. Do you see the issue with this experimental method?
