The hormone testosterone (T) has a central role in recent theories about allocation of status ranks during face-to-face competition. It has been methodologically convenient to test the hypothesized T mechanism in physically taxing athletic contests, where results have been supportive, although their generalizability to normal social competition is questionable. Competition among chess players is a step closer to normal social competition because it does not require physical struggle, and it is the arena for tests of the T mechanism which are reported here. We find that winners of chess tournaments show higher T levels than do losers. Also, in certain circumstances, competitors show rises in T before their games, as if in preparation for the contests. These results generally support recent theories about the role of T in the allocation of status ranks.

Representative of a number of articles, this one says that to raise testosterone levels naturally:
- Eat eggs, whey, meat and nuts, especially peanuts.
- Lower body fat percentage.
- Weight-bearing exercises, especially low-reps with max weight.
- Limit alcohol consumption.
- Get sufficient sleep.
All of which sound intriguing on their own merits, as methods of feeling good AND possibly raising your USCF rating through means other than tactical training.
