Several studies have investigated supplement and drug use prevalence among elite athletes. However, nonelite athletes who exercise in gyms to improve their health and appearance have received less attention. The present study aimed to evaluate the prevalence of supplement use in recreational athletes in Fars, Iran. In this cross-sectional study, 256 recreational athletes (165 men and 91 women, mean age 28.67±7.28) completed the questionnaire (researcher-made), and the differential validity was estimated by the comparison of novice and elite athletes using the Kruskal-Wallis test. Moreover, the reliability of the instrument was confirmed based on internal consistency (Cronbach’s alpha) and stability (repeatability) using test-retest (correlationcoefficient of the test scores). Data analysis was performed using descriptive statistics. In this study, 84% of the participants used various supplements, and 54% consumed performance-enhancing and occasional drugs. The most common supplements were multivitamins (77.7%), protein powders (69.1%), fish oil (47.9%), and vitamin D (39.9%). According to the findings, 46.8% of the subjects consumed supplements to improve their physical appearance, while 21.8% used these substances to enhance their health. Meanwhile, 62.2% of the athletes considered themselves fit (not obese/lean), while 31.1% and 33.3% tended to lose weight and slightly gain weight, respectively. According to the results, the rate of consuming supplements, weight loss drugs, occasional drugs, and performance-enhancing drugs was high in the recreational athletes in Fars province, which indicated the necessity of more control and attention to the prevention of excess supplement use and raising awareness in this regard.

 Doping is known as an important public health problem. Prominent sports events can be blemished due to doping. The role of general practitioners as an important part of the health system in the prevention of doping is obvious. Previous studies have shown they have been presumed themselves ill-prepared in dealing with this topic. This study set out to investigate the amount of knowledge and attitude among medical interns toward doping.

 This cross-sectional study was conducted on 100 medical interns in Taleghani hospital, Tehran, Iran Subjects were asked to complete a 35-item questionnaire. The questionnaire consisted of four parts: demographic data, status of physical activity, knowledge, and attitude. Knowledge was measured by questions regarding identifying prohibited drugs, adverse effects of banned drugs, WADA as an original source of published list of prohibited drugs, and regulations related to anti-doping rules violation. The attitude was measured based on a 5-point Likert scale. The more negative attitude toward doping was shown by higher scores.

 The mean age was 25.39+/-1.43. Only 8% of students were familiar with WADA as an original source of doping. Approximately 90% of students were not aware of sanctions of anti-doping rules infraction. 65%, 33% and 2% of our subjects had poor, good and very good knowledge respectively. The mean score of attitude was 19.68+/-2.88.

 Our findings revealed, the senior medical students had negative attitudes toward doping and also their level of knowledge was poor in this regard.

The prevalence of high-risk behaviors among professional athletes as role models for their fans, especially adolescents and young people, is important to be considered. Thus, this study aimed to investigate the prevalence of HRBs in Iranian professional athletes. This cross-sectional study included 1,940 athletes that were active in eight popular sports from 12 cities of the country. Data were collected using stratified random sampling and a self-made high-risk behavior questionnaire. To analyze the data, descriptive statistical methods were used. The results showed the prevalence of doping among professional athletes was 3%. Besides, 0.3% of the professional athletes on average smoke daily, and 2% used shisha (smoking water pipes) daily. Moreover, 2.5% of professional athletes drunk alcohol at least one time per month. Also, the prevalence of violence involvement among professional athletes was 4.1%, and the prevalence of illicit drug use was 0.3%. The research results showed all high-risk behaviors were prevalent to some degree among professional athletes.

Through doping, we understand the use by athletes of substances prohibited by the anti-doping agencies in order to gain a competitive advantage. Since sport plays an important role in physical and mental education and in promoting international understanding and cooperation, the widespread use of doping products and methods has consequences not only on health of the athletes, but also upon the image of sport. Thus, doping in sports is forbidden for both ethical and medical reasons. Narcotics and analgesics, anabolic steroids, hormones, selective androgen receptor modulators are among the most frequently utilized substances. Although antidoping controls are becoming more rigorous, doping and, very importantly, masking doping methods are also advancing, and these are usually one step ahead of doping detection techniques. Depending on the sport practiced and the physical attributes it requires, the athletes will look for one or more of the following benefits of doping: recovering from an injury, increasing body recovery capacity after training, increasing muscle mass and strength, decreasing fat tissue, increasing endurance. Finally, when we look once again at a doping scandal, amazed at how much animosity against those caught can exist; the question is: is it really such a disaster as presented by the media or a silent truth under our eyes, but which many of us have refused to accept?

Consumption of codeine can lead to positive urine test for morphine in athletes. Morphine is classified as a prohibited doping drug while Codeine is not. Morphine/codeine ratio is used in forensic medicine to distinguish the consumption of codeine from abuse of morphine and other narcotics. We present an athlete with positive urine test for morphine with a history of consumption of codeine. The disciplinary committee came to conclusion that the athlete had not consumed morphine and did not violate doping code based on morphine/codeine ratio. Analysis of codeine to morphine metabolism rate is needed when we are using morphine/codeine ratio to rule out abuse of narcotics. WADA should consider analysis for the CYP2D6 alleles (main metabolizer of codeine) in case of including morphine/codeine ratio in future prohibited list. The possibility of ultra-rapid CYP2D6 cannot be ruled out in certain results of morphine/codeine near the cut point.

We express the detection of the prohibited substance prednisone, prednisolone in player’s urine sample by long and intensive use eye steroid drops.. In a rare case in Iranian football, a player’s urine sample had corticosteroids. After all investigations, it was demonstrated that systemic effects can be induced by using long-term of ophthalmic prednisone.. It seems to be required to investigate the systemic effects on long term and excessive use of topical corticosteroid drops can have on the result of the sample analysis and showing positive results..

Nowadays, doping is an intricate dilemma. Football is the nationally popular sport in Iran. On the other hand, doping is a serious health hazard sport faces today. Studies dealing with athletes’ knowledge, attitudes and behavior concerning doping in football are scarce. Therefore, we aimed to investigate the knowledge and attitudes toward doping among the football coaches and players.Patients and In a cross sectional study, 375 participants (239 football players and 136 coaches) were studied. A specially made questionnaire was applied. In this study, football teams of different provinces of the country were selected by randomized clustered sampling and questionnaires were distributed among coaches and players. Knowledge of football coaches and players in three categories of doping definitions, recognition of prohibited drugs and side effects of anabolic steroids was poor or moderate in 45.3%, 88.5% and 96.5%, respectively. Football players and coaches have poor knowledge about doping in Iran. Moreover, they believe in some inappropriate myths without any scientific or rational basis.It seems necessary to design a comprehensive educational program for all of the athletes and coaches in Iran.

The self-administration intake of anabolic-androgenic steroids (AAS) is a widespread practice in competitive bodybuilders. Structural changes within the myocardium following AAS abuse including hypertrophy, restricted diastolic function as well as systolic dysfunction and impaired ventricular inflow have been reported. We present the case of a 39-year-old bodybuilder with a more than 20-year history of anabolic-androgenic steroids (AAS) abuse presenting with increasing exertional dyspnoea and fatigue. Diagnostic work-up of the patient’s current symptoms included a cine cardiovascular magnetic resonance (CMR). Using a T1-weighted inversion-recovery sequence 10 minutes after application of 0.1 mmol/kg gadolinium with diethylenetriaminepentaacetic acid (gadolinium DTPA), patchy midwall enhancement in the septal and posterolateral region of the left ventricle was demonstrated. This enhancement pattern is different from the enhancement pattern found in patients with ischemic heart disease. The present case illustrates for the first time, by CMR, myocardial scarring with severe left ventricular hypertrophy in a patient with normal coronary arteries after long lasting abuse of AAS. With that finding we could demonstrate a link between AAS abuse and the occurrence of myocardial scarring in humans. This finding may help raise awareness of the consequences of AAS use.
