We supplemented this by searching the bibliographies of major review articles published in these content areas. We also added to the reference list any additional references that were known to the members of the writing group but did not appear in this search. The expert panel reviewed and synthesized evidence in their areas of expertise and prepared the Scientific Statement. The SSTF, the Advocacy and Public Outreach Core Committee, and the Council of The Endocrine Society reviewed the Scientific Statement. The chair selected a 6-member expert panel (approved by The Endocrine Society) with expertise in the use and health consequences of PEDs.
What Are Some Popular Substances Athletes Abuse?
- Stanozolol is a 17α-alkylated androgen that can be taken orally or by injection.
- Whatever the case, it’s clear that positive drug tests are much more prevalent in today’s sports than they were even ten years ago.
- Abuse of some stimulants has been shown to age the cardiovascular system more aggressively than smoking.
- However, as we’ll discuss more below, players who come forward with a drug abuse problem receive league-paid treatment.
Few studies of the effects of diuretics on athletes have been published recently because in recent times, most studies assessing doping agents and exercise and sport have focused on newer drugs and methods of performance enhancement. Diuretic use for the masking of other prohibited substances remains a serious problem, however. The younger brain is more susceptible to excessive energy drink consumption and a high risk for disturbed neurodevelopment in children and adolescents has also been reported.157 Additionally, individuals with underlying cardiovascular pathology should avoid energy drinks unless approved by their physician. Using drugs often compromises judgment and physical abilities, and make a person unable to perform in a variety of contexts. Sports and injuries go hand and hand, but what sports do not account for are or tolerate are drugs and substance abuse.
- Osmotic diuretics are a class of non-metabolizable low-molecular-weight compounds.
- Steroid users may become overly aggressive or combative, a condition commonly referred to as “’roid rage.” Uncontrolled aggression causes some steroid users to become confrontational with friends and family; sometimes, they end up in trouble with the law.
- They are quickly and widely absorbed from the gastrointestinal tract (65–90%) but have a very short half-life (less than 1 h for bumetanide and piretanide and a maximum of 3.5 h for torsemide).
- Finally, thiazide diuretics are derivatives of sulphonamides and can cause photosensitivity if exercising outdoors during midday hours.
General remarks
The half-lives range from less than 1 h in the case of glycerin and mannitol to almost 10 h for isosorbide. Because of their sulphonamide-based structure, some loop diuretics have weak CA-inhibiting activity that further increases the diuretic effect of these drugs. Moreover, they have direct vascular effects (Dormans et al., 1996) that negative effects of drugs in sport acutely increase systemic venous capacitance and decreases left ventricular filling pressure. This effect, particularly evident for furosemide, benefits patients with pulmonary oedema even before diuresis ensues. The substances discussed in this issue probably all have a legitimate role in treating pain in various medical conditions.
- In higher doses, stimulants can also lead to more severe health effects, such as rapid heart rate and high blood pressure.
- Therefore, studies of PEDs in animal models provide important comparisons with the human data.
- Athletes might need prolonged anti-epileptics drug treatment and these drugs might have pharmacokinetic interactions with other drugs.
- Blood doping – this involves removing blood and then re-transfusing it a few weeks later after the lost red blood cells have been replaced.
- Sixth, PED use rarely brings individuals to emergency rooms, because the most widely used class of PEDs, AASs, rarely precipitate a medical emergency comparable to an overdose of alcohol or heroin.
Nondrug performance-enhancing measures
Under these circumstances, the cellular targets and mechanisms of action may be substantially different from the effects at normal physiologic levels. Another concern relates to the possible interaction of AASs with CNS injuries, including traumatic brain injury and posttraumatic stress disorder. In recent years, clinical, scientific, and public attention has focused on the chronic neurologic and behavioral effects of head injuries in football players and soldiers (400). These may represent the accumulated effects of repeated mild head trauma (in football players) or the lasting response to blast exposure (in soldiers).
Globally, anti-doping efforts are led by the World Anti-Doping Agency (WADA), the umbrella organisation responsible for policymaking and harmonisation (WADA, 2019). Doping is commonly understood as the use of prohibited performance enhancing substances or methods in sport. The official definition accepted by most sport organisations and athletes is that doping is the violation of one of the anti-doping rules laid out in the World Anti-Doping Code. The WADA Code (2019) includes as its fundamental rationale the promotion of athlete health. In this view, health promotion is achieved by prohibiting athletes from using substances for which ‘medical or other scientific evidence, pharmacological effect or experience that the Use of the substance or method represents an actual or potential health risk to the Athlete’ (WADA, 2019, p.30). Ostensibly, this is related to the perceived health risks of doping substances, though it is also related to broader war on drugs style policies and politics (Coomber, 2014; Dimeo, 2007).
Effects of Performance-Enhancing Drugs
This review provides an overview of the pharmacology and toxicology of diuretics and discusses their application in sports. The most common analytical strategies currently followed by the anti-doping laboratories accredited by the WADA are discussed along with the challenges laboratories face for the analysis of this diverse class of drugs. Despite the growing research on a range of recreational drug risk and enabling environments, very little research has been done to similarly understand the environments in which doping occurs. One qualitative study with cyclists that has engaged with the risk environment framework looked specifically at the issues of employment and labour precariousness as factors that may lead to doping (Aubel & Ohl, 2014).
We begin with a background on doping and anti-doping, risk and enabling environments, and sport risk and enabling environments. We then present a theoretically explorative discussion on the specific anti-doping risk/doping enabling processes and environments, using known cases of systematic doping as illustration. We conclude with a comparison of sport and non-sport responses to drug use and the potential outcomes of each approach. In addition to the methodologic problems that have limited the success of gene therapy to date (such as limited expression of the recombinant protein and gene silencing), many safety issues remain to be resolved (385, 404,–408).
- One way of avoiding some of these issues is for athletes to collectively dope, thereby sharing the burden of risks and working together to minimize them.
- An isoelectric focusing method separates the isoforms of erythropoietin, which are detected using double immunoblotting chemiluminiscence (390, 391).
- It is reported that most athletes get nutritional advice from coaches, fellow athletes, family members and friends,169 suggesting that more wide reaching educational interventions, at an early age, are necessary.

Ventura and Segura published a comprehensive review of diuretic analysis in 1996 (Ventura and Segura, 1996). This review will mainly focus on the developments and techniques https://ecosoberhouse.com/article/best-way-to-flush-alcohol-out-of-your-system/ that have been developed since that time. This article is an extension of the British Journal of Pharmacology special themed issue, Drugs in Sport (McGrath and Cowan, 2008).
