Testosterone May Be Secret to Home Team Advantage

LONDON (Reuters Health) - A pre-match surge in levels of the hormone testosterone could explain why football teams playing on their home ground are more likely to win, new research suggests.

An experiment involving professional football players in the UK showed a 50% rise in testosterone levels before a home game, but no real change before playing at another team's ground or prior to a training session.

Researchers from the University of Northumbria said the findings probably reflect a primeval urge to defend home territory against enemy attackers. An increase in testosterone is associated with aggression, confidence and dominance.

"There have been lots of studies showing that in men's sport, winners see a big boost in testosterone, while in losers it stays level or drops," Dr. Nick Neave, a biological psychologist at the University of Northumbria, said in an interview with Reuters Health. "So we were interested to see if it was related to home advantage in football players.

"When animals defend their home territory they fight hard and are more likely to win--even if they are smaller than their enemy."

Many explanations have been put forward for the home advantage in football--known as soccer in the US--including more vocal crowd support, referee bias and familiarity with the venue.

But the latest findings, presented at the annual conference of the British Psychological Society in Blackpool, could provide an alternative biological explanation.

Researchers took saliva samples from players in an English Premier League club's under-19 squad before two home matches, two away matches and two training sessions.

Before the away game and the training session, average testosterone levels were around 100 picogrammes per millilitre (pg/mL).

But before a home game against a major rival team, they jumped to around 150 pg/mL.

Neave added, "What was really interesting was that, when we looked at the positions of the players, the goalkeeper during training had some of the lowest levels of testosterone. But for home games their levels were much bigger because they are actually defending their territory--they are the last line of defence."

But he stressed it remains unclear whether higher levels of the hormone can actually improve physical performance, or whether the effects are due to increased stamina and determination.

"Testosterone does have affects on the brain related to spatial ability. And in football, awareness of where a moving object is is very important."

Okay, Mister Smarty Pants, let's see you run kids all over the place from dawn to dark, referee car fights, shop for dinner, cook it in your tidy little home(that everyone else constantly tries to destroy) and still look fabulous.
Sorry buddy, it's an estrogen thing.
We have the advantage at home and away.

Maybe, but does this mean women don't have home field advantage? I think there's a more social explanation.

1. Travel. The visitors have just gotten off an airplane and are going to be more tired on average.
2. Fan support. More people are going to be cheering for the home team than the visitors.
3. Stadium size. Home field advantage is more pronounced in basketball and hockey. I think this is due to the smaller stadium size. It's relatively easy to fill a basketball court with noise. It's much harder to fill a baseball stadium with noise.

Anyway, that's my opinion.

All good points, but it's also hard to deny the effects of increased testosterone on men (and women, for that matter).
