(muscle-building) actions
hence, they are known collectively as anabolicandrogenic steroids (aas)
whether of endogenous or exogenous origin in males and in females, excess testosterone creates an advantage in sports (acsm, 2006)
until recently, this concept was a matter of debate within the clinical and scientific community
while the anabolic effects of testosterone in hypogonadal males were well-accepted, early studies testing the effects of testosterone supplementation to eugonadal men were not well-controlled (reviewed in bhasin et al, 2004)
more recent studies have shown that testosterone stimulates muscle mass (storer et al, 2003) and reduces body fat (bhasin et al, 2004)
androgens likely also act on specific substrates in the brain to increase aggression and motivation for competition (gleason et al
athletes aim to maximize their performance through the anabolic effects of testosterone and aas, while limiting androgenic actions
starting in the mid-1930’s after the chemical structure was published, testosterone’s potential as a performance-enhancing drug was recognized and exploited by athletes
use of androgens in athletics expanded in the 1950s and 1960s (van amsterdam et al, 2010), coinciding with the development of synthetic aas
exogenous testosterone has been banned from olympic competition since 1976, and was classified in the united states as a controlled substance by the anabolic steroid control act of 1990
testosterone is normally present in the circulation of both men and women
due to the dynamic regulation of endogenous testosterone production, including the acute effects of competition and exercise, testosterone concentrations may vary considerably within and among individuals
accordingly, it has been difficult to establish a threshold separating endogenous testosterone from exogenous sources
furthermore, disorders of sexual differentiation (dsd) can produce elevated concentrations of endogenous androgens, potentially creating a competitive advantage for female athletes with dsd
for women with dsd, the standards for inclusion in major athletic competition continue to evolve
defining the upper limit for endogenous testosterone is complicated by the dynamic changes in testosterone across a number of temporal scales
on the shortest time-scale, testosterone production in the gonads follows the pulsatile release of luteinizing hormone
this introduces a level of unpredictability for estimating circulating androgen concentrations in any single biologic sample
secondly, in both sexes, testosterone follows a diurnal rhythm with peak concentrations in the morning followed by progressive decline over the course of the day, rising again at night during sleep (dabbs, 1990a)
in women, there is evidence that testosterone concentrations also vary as a function of the menstrual cycle, with peak testosterone concentrations in the periovulatory window, and lower values in the early follicular and late luteal phases (dabbs and la rue, 1991)
on a somewhat longer time-scale, testosterone concentrations exhibit circannual variation and peak in the fall (dabbs, 1990b; stanton et al
, 2011; van anders et al, 2006)
lastly, men’s testosterone concentrations slowly decline over the lifespan (dabbs, 1990b) while women face an abrupt decline in testosterone at menopause (schwenkhagen, 2007)
exercise and competition also acutely alter testosterone concentrations, with obvious relevance to urine samples collected directly after athletic competition that are to be used for doping assessment
generally, cardiovascular exercise and resistance training transiently increase testosterone concentrations in men (reviewed in hackney [2001], kraemer and ratamess [2005]) and women (enea et al
, 2009), although a few studies report null effects
testosterone concentrations also vary both before and after competition in a systematic and consistent manner
wingfield and colleagues (1990) proposed the “challenge hypothesis”, which posits that during mating seasons and times of resource scarcity testosterone concentrations rise to facilitate competition, particularly amongst males
the challenge hypothesis is relevant to human competition in the world of sports (archer, 2006)
an athletic match is a competition between individuals over a scarce and valuable resource (e
victory itself, prize money, fame, prestige)
as predicted by the challenge hypothesis, pre-competition concentrations of testosterone rise in male and female athletes in anticipation of the impending competition (bateup et al, 2002; booth et al
, 1989; edwards and kurlander, 2010; mazur et al
, 2009; salvador et al, 2003; suay et al, 1999)
we speculate that the pre-competition increase in testosterone may facilitate competition by both increasing motivation to compete (booth et al
, 1989) and physical ability, but further studies of the mediating effects of pre-competition testosterone increases on changes in motivation and physical ability are needed
in men, testosterone commonly increases following victory and decreases following loss (booth et al
, 1989; elias, 1981; gladue et al
, 1992; mazur & lamb, 1980; mccaul et al
, 2009), including experiences of vicarious victory and defeat (bernhardt et al
, 1998; stanton, beehner, et al
although, this main effect of winning or losing on changes in men’s testosterone is not always observed (gonzalez-bono et al
, 1999; van anders & watson, 2007)
several studies have shown that other factors like context (carre, 2009), individual differences, e
, power motivation (schultheiss et al
, 1999; schultheiss & rohde, 2002; schultheiss et al
, 2005; stanton & schultheiss, 2009), social anxiety (maner et al
, 2008), and motivation to win (suay et al
, 1999), as well as cognitive appraisal (reviewed in salvador & costa, 2009; salvador et al
, 1999; van der meij et al
, 2010) can play an important role in predicting post-competition testosterone changes
dominance-motivated individuals, who positively value interpersonal dominance and dislike submission, are those most likely to experience outcome-dependent changes in testosterone (schultheiss, 2007; stanton and schultheiss, 2009)
competitors’ level of engagement is also relevant to testosterone changes (van der meij et al, 2010), such that men’s testosterone increases are greatest when one’s opponents feel more confident
an elite athlete in an international competition is likely to be more engaged and to value victory and defeat much more significantly than a participant in laboratory manipulations with cognitive games
accordingly, testosterone changes in situations of high value and importance are likely to be of greater magnitude
the “winner effect” and “loser effect” describe the post-competition changes in behavior as a function of winning and losing the contest, in which testosterone appears to be differentially involved
the winner effect describes the increases in dominance engagement and likelihood of winning future fights after recently winning dominance competitions, and the loser effect describes the withdrawal from and increased chances of losing further dominance interactions after losing recent fights (dugatkin, 1997; gleason et al
both of these effects are argued to have adaptive benefits
a winner will likely benefit from continued victory and increased access to resources, whereas a loser, who may be injured or still in the presence of the victory-primed winner, will likely benefit from disengagement (mazur, 1985)
several animal studies have elucidated the mediating effects of testosterone in the winner and loser effect, which have been subsequently studied in
