To measure a profile of hormones in a group of elite athletes. Increasing awareness of the widespread use of hormones as performance‐enhancing agents focusses attention on what may be considered as normal in this unusual group. 

Sex, health, and athletes

Recent policy introduced by the International Olympic Committee to regulate hyperandrogenism in female athletes could lead to unnecessary treatment and may be unethical, argue Rebecca Jordan-Young,

Is testosterone responsible for athletic success in female athletes?

TLDR
The data suggest that the measurement of the serum T levels significantly correlates with athletic success in sprinters but not other types of athletes and in the future may be useful in the prediction of sprinting ability.

Androgens and athletic performance of elite female athletes

TLDR
Results obtained from recent neuropsychological studies indicated that testosterone, and not the sex chromosomes, is responsible for the sexual differentiation of visuospatial neural activation, which could explain how males and hyperandrogenic females benefit from androgens performance-enhancing effects in sports where visuosphere abilities are closely linked to better performance.

Female hyperandrogenism and elite sport

Emerging evidence indicates that testosterone, which can increase muscle mass and strength, stimulates erythropoiesis, promotes competitive behaviour, and enhances the physical performance of women.

Laboratory medicine: health evaluation in elite athletes

TLDR
The main biochemical and haematological markers that vary significantly during and after sports training are defined to identify risk factors, at competitive and professional levels and to highlight the set up of a specific parameter’s panel for elite athletes.

Testosterone, Athletic Context, Oral Contraceptive Use, and Competitive Persistence in Women

The purpose of this study is to provide a descriptive account of salivary testosterone levels in women in relation to being an athlete, sporting level, competitive context, and oral contraceptive

Determination and regulation of body composition in elite athletes

TLDR
This review covers the scientific knowledge about the development and regulation of body composition in humans but also considers the lessons learnt from evolution and breeding in animals and the key factors determining body composition are considered.

TLDR
This review covers the scientific knowledge about the development and regulation of body composition in humans but also considers the lessons learnt from evolution and breeding in animals and the key factors determining body composition are considered.

Why do endocrine profiles in elite athletes differ between sports?

TLDR
It is unclear whether the differences in hormone profiles between sports is a reason why they become elite athletes in that sport or is a consequence of the arduous processes involved and this may well be true for endocrine profiles.

  • S. Basaria
  • Biology

TLDR
The development of sensitive detection techniques may help discourage (at least to some extent) the abuse of these compounds and be used as an opportunity to educate both athletes and the general population regarding their adverse effects.

Running--an analogue of anorexia?

TLDR
The apparent similarity between patients with anorexia nervosa and a subgroup of male athletes designated as "obligatory runners" is explored, suggesting that both phenomena could represent a partially successful--albeit dangerous--attempt to establish an identity.

Toward the development of a test for growth hormone (GH) abuse: a study of extreme physiological ranges of GH-dependent markers in 813 elite athletes in the postcompetition setting.

TLDR
It is demonstrated that there are predictable age-dependent levels of GH-dependent markers in elite athletes that are consistent even at the extremes of physical exertion and that these are independent of sporting category.

Effect of altered reproductive function and lowered testosterone levels on bone density in male endurance athletes

TLDR
The aim of this brief review is to present the limited literature on the relation between bone density and testosterone levels in male endurance athletes.

Out of Bounds? A Critique of the New Policies on Hyperandrogenism in Elite Female Athletes

TLDR
The new policies in response to Caster Semenya's case are questioned on three grounds: the underlying scientific assumptions; the policymaking process; and the potential to achieve fairness for female athletes.

Adrenal activation and the prolactin response to exercise in eumenorrheic and amenorrheic runners.

TLDR
It is concluded that control for menstrual phase in ER is important in studies of prolactin responses following exercise but not in Studies of ACTH and cortisol responses followingercise, and cortisol responding following submaximal and maximal exercise in AR are blunted at the adrenal level.

The athlete biological passport.

TLDR
The Athlete Biological Passport can also serve as a platform for a Rule of Sport, with the presentation before competition of the ABP to objectively demonstrate that the athlete will participate in a healthy physiological condition that is unaltered by performance-enhancing drugs.

Hormonal changes in serum in young men during prolonged physical strain

TLDR
Short periods of sleep (3–6 h) were shown to be effective in reversing the changes described in this paper, especially for growth hormone, prolactin, and testosterone.

The science and management of sex verification in sport

TLDR
The present review provides the historical context to the debate, identifying the origins of gender verification as a means to deter cheating and describing how various testing methods have been attempted, including physical examinations of genitalia, molecular techniques including genetic screening, and complex multidisciplinary approaches including endocrinological, genetic and gynaecological examination.

Responses of markers of bone and collagen turnover to exercise, growth hormone (GH) administration, and GH withdrawal in trained adult males.

TLDR
It is concluded that endurance exercise transiently activates bone and collagen turnover and brief GH administration results in similar but quantitatively greater augmentation; and these data will assist in designing a GH detection strategy.
