The Impact of Competitive Sports on Testosterone Levels

A new study spearheaded by the University of Missouri reveals fluctuating testosterone levels during group competitions, suggesting a correlation between competitors' relationships and their hormonal fluctuations. This relationship may extend to the formation of alliances in warfare. This aspect seems unique to our species, making humans the only animal that competes in teams.

Hormonal Reactions Dictated by Social Circumstances
According to renowned Anthropology Professor Mark Flinn at the University of Missouri, humans evolved as a cooperative species, which is evident from our hormonal reactions during competitive scenarios. The study found that male testosterone levels rise following victories against strangers or rivals. However, these levels remain stable when the competition involves friends.

Observations from the Field
To derive these insights, the research team studied men from various age groups engaged in playing games such as dominoes or cricket in Dominica. Whenever these men competed against individuals outside of their community, their testosterone levels escalated during and after the victory in these games. If they experienced defeat, however, their hormone levels took a downward turn. Intriguingly, there was no significant fluctuation in hormone levels when the men battled their friends, with testosterone level staying consistent, irrespective of victory or defeat.

The Influence of Group Collaboration and Spectatorship
The study further indicated that testosterone levels in males rise not only due to participation in sports alliances but also while merely viewing the event. As Flinn explains, being a part of the community of fans, especially when supporting a favorite sports team, may lead to a spike in testosterone levels.

Hormonal Fluctuation and Human Social Psychology
The study suggests that these findings may have significant implications on the understanding of human social psychology's evolution. According to Flinn, the complexity of human social psychology is evident in our ability to anticipate and predict outcomes based on the actions and interactions of entire teams, whether as a participant or viewer. Humans' ability to anticipate team reactions is a unique attribute that truly sets our species apart.

By revealing links between testosterone fluctuations and social situations, this study illuminates new spheres of understanding about the hormonal impact of competitive sports, both on the participants and the spectators.
