In many articles that I’ve found on the web, they cite a “Temple University study” that says that chess burns a lot of calories, players testosterone levels increase, etc.
However, I have not been able to find the original study. Can anyone help?
Around 20 years ago ago a researcher, then at the University of Nebraska, conducted a study of several types of competitive players, including, as I recall, chess players and tennis players. They measured testosterone levels for several players (all at the expert level or higher, I believe) several times during a chess tournament. (I think they did it at two or three tournaments.)
The researcher left for another institution before the article was published. I think this is the abstract of that article, though it doesn’t appear to be the Temple University one. I think Alan Booth is the person who was at UNL.

If you have access to SSCI (Social Science Citation Index), you can look for articles which cite this one, that may lead you to the other study you’re looking for.
Almost any organizer can tell you from first-hand experience that chess players produce a lot more heat than an equivalent number of adults in a meeting room. I always advise hotels of this, so that they can plan their air conditioning setting and water stations accordingly.
So chess players are another cause of global warming?
