"In recent years, antidoping research has identified contaminated nutritional supplements and food as the principal sources of inadvertent doping. Nutritional supplements have been contaminated with various stimulants, β2-agonists, prohormones, ‘classic’ anabolic steroids and non-approved designer steroids.32 33 "
[Show abstract][Hide abstract] ABSTRACT: A medical and scientific multidisciplinary consensus meeting was held from 29 to 30 November 2013 on Anti-Doping in Sport at the Home of FIFA in Zurich, Switzerland, to create a roadmap for the implementation of the 2015 World Anti-Doping Code. The consensus statement and accompanying papers set out the priorities for the antidoping community in research, science and medicine. The participants achieved consensus on a strategy for the implementation of the 2015 World Anti-Doping Code. Key components of this strategy include: (1) sport-specific risk assessment, (2) prevalence measurement, (3) sport-specific test distribution plans, (4) storage and reanalysis, (5) analytical challenges, (6) forensic intelligence, (7) psychological approach to optimise the most deterrent effect, (8) the Athlete Biological Passport (ABP) and confounding factors, (9) data management system (Anti-Doping Administration & Management System (ADAMS), (10) education, (11) research needs and necessary advances, (12) inadvertent doping and (13) management and ethics: biological data. True implementation of the 2015 World Anti-Doping Code will depend largely on the ability to align thinking around these core concepts and strategies. FIFA, jointly with all other engaged International Federations of sports (Ifs), the International Olympic Committee (IOC) and World Anti-Doping Agency (WADA), are ideally placed to lead transformational change with the unwavering support of the wider antidoping community. The outcome of the consensus meeting was the creation of the ad hoc Working Group charged with the responsibility of moving this agenda forward.

[Show abstract][Hide abstract] ABSTRACT: This study aimed to characterise the nutritional intake according the use of nutritional supplements (NS) by elite adult Portuguese athletes. Two hundred and two adult (23±4 years) athletes (78% males), representatives of Portugal in 13 sports, voluntarily filled a semiquantitative food-frequency questionnaire and a questionnaire about the use of NS. The total nutritional daily intake did not consider the nutrients provided by NS. Statistical analyses were performed using SPSS V.16.0. The majority of athletes (74%) reported having used at least one NS in the previous year, with a mean consumption of 5.9±3.7 NS per athlete. The most frequently consumed nutritional supplements were sport drinks (63%), proteins (58%), magnesium (56%), iron (30%), vitamin C (29%), sport gels (23%), antioxidants (21%), vitamin B12 (15%) and vitamin E (9%). The mean energy intake was 2875±1313 kcal/days, for males, and 2612±1152 kcal/days, for females. For proteins, the males' intake was 1.7±0.8 g/kg/days and females' intake was 2.1±1.2 g/kg/days. Males consumed 4.8±2.5 g/kg/days of carbohydrates, while females consumed 5.6±2.6 g/kg/days. Intake of less than recommended was observed in 33% for vitamin E in females, and 17% for vitamin E, 5% for folate and 5% for magnesium, in male athletes. For all other micronutrients intakes were above recommended amounts for both genders. There were no differences in the vitamin and mineral intake between supplement users and nonusers, for both genders. The use of NS is very prevalent in elite adult Portuguese athletes and not associated with nutritional total intake.
