|dc.description.abstract||Many studies investigating the relationship between hormones and
competition have focused on athletic competition. The athletic setting enables
researchers to investigate the hormone-behaviour relationship in a relatively
controlled environment. However, research to date has been based on observations
made from single status contests and/or weekend tournaments and as such, does not
provide a clear picture of an individual's average hormonal responses to both victory
In appreciation of this limitation, the current study tracked elite hockey
players throughout a hockey season, measuring pre- and post-game salivary
testosterone and Cortisol as well as psychological measures. I was interested in
determining whether status outcome (win vs. loss) would influence an individual's
testosterone and Cortisol responses to competition. Furthermore, I was also interested
in assessing whether testosterone and Cortisol responses were specific to the
competitive environment or whether similar hormonal responses would occur during
non-competitive practice sessions. Last, I was interested in whether there were any
differences in pre-game hormonal and psychological states depending on where the
status contest was held: home versus away.
The results indicated that game outcome moderated the testosterone responses
to competition. That is, testosterone increased significantly more after a victory
compared to a defeat. Furthermore, a loss of status produced significantly hreports, the players did not show an anticipatory rise in either Cortisol or testosterone
prior to competition.
In addition to the effects of status outcome on hormonal levels, it was also
found that these hormonal responses were specific to competition. The athletes in the
current study did not demonstrate any hormonal responses to the practice sessions.
Last, there were significant differences in pre-game testosterone as well as in selfconfidence,
cognitive, and somatic anxiety levels depending on the location at which
the status contest took place. Pre-game testosterone and self-confidence levels were
significantly higher prior to games played in the home venue. In contrast, pre-game
somatic and cognitive anxiety levels were significantly higher prior to games played
in the away venue.
The current findings add to the developing literature on the relationship
between hormones and competition. This was the first study to detect a moderating
effect of status outcome on testosterone responses in a team sport. Furthermore, this
was also the first study in humans to demonstrate that post-contest Cortisol levels
were significantly higher after a loss of status. Last, the current study also adds to the
sport psychology literature by demonstrating that pre-game psychological variables
differ depending on where the status contest is being held: higher self-confidence at
home and higher somatic and cognitive anxiety away. Taken together, the results
from the current thesis may have important practical relevance to coaches, trainers
and sport psychologists who are always trying to find ways to maximize performance.
