The knowledge, attitudes and use of performance enhancing substances and supplements among male high school first- and second team athletes in the central metropolitan area of Cape Town, South Africa

Van Aswegen, Mariaan 25 August 2014 (has links)
Title: The knowledge, attitudes and use of performance enhancing substances and supplements among male High-school first and second team athletes in the metropolitan area of Cape Town, South Africa. Objective: Pressure to perform and to achieve success is to many high school athletes the overbearing goal and reality. Many are willing to use substances to achieve their goals even at the expense of their health and wellbeing. Four objectives emanated from this research: To determine the most frequently used sport performance enhancing substances and supplements (PESS) by male high school athletes; to evaluate the prevalence and use of PESS; to determine the main sources of information on PESS to determine the knowledge and lastly to determine the perceptions and attitudes of male high school athletes on PESS usage. Design: This study used a prospective cross sectional survey design. A self-administered questionnaire was employed to assess the participant’s knowledge, perceptions, attitude toward and use of PESS. The selected sample was male athletes in high schools in the central metropolitan area in Cape Town that were involved in competitive sports at the first and second team level. Results: One hundred and twenty two male athletes from four schools in the central metropolitan area of Cape Town participated. No serious PESS use was found. The main first choice of reported sources of information regarding PESS was pharmacists (21.3%), biokineticists (16.4%) and the internet (16.4%). The participants’ knowledge, perception and attitude toward the use of PESS was found to be poor. Conclusion: Most athletes reported to gather information from pharmacists (21.3%) and biokineticists which is encouraging since it is expected of these professionals to provide sound advice. It is suggested to create awareness among such professionals regarding use of PESS by this population and to incorporate organizations such as SAIDS and WADA as part of this dissemination of knowledge. The knowledge, perceptions and attitude toward PESS use by male high school athletes appears to be lacking thus indicating the need for more education on PESS.

The use of performance enhancing substances by adolescent male athletes in selected Johannesburg boys' high schools

Gradidge, Philippe Jean-Luc 14 February 2011 (has links)
MSc (Med), Biokinetics, Faculty of Health Sciences, University of the Witwatersrand / Introduction: Performance enhancing substance (PES) use is a major concern currently facing adolescent sport. The youth have become more competitive in sport, with some using substances and supplements to improve their performance. Unfortunately, some of these adolescent athletes are using substances that are both harmful to their health and prohibited. Aim of study: To establish the attitudes and perceptions towards and the use of PES, including prohibited substances and food supplements, by adolescent male athletes, in selected Johannesburg boys’ high schools. Method: The study design was a cross-sectional study using a self-administered questionnaire. Male adolescent high school learners involved in 1st and 2nd team competitive high school sport in seven Johannesburg boys’ high schools were invited to volunteer to participate in the study. Questionnaires were completed under conditions similar to an examination, where participants were not allowed to communicate with each other. Demographic data was analysed using descriptive statistics. Results: The sample size was 100. Results indicated that the prevalence of PES use amongst the participants was 30%. The use of prohibited substances was found, including growth hormone (5%), anabolic androgenic steroids (4%), and adrenaline (4%). Food supplement use was also found in this sample, including creatine (32%), protein (61%), carbohydrate (54%), caffeine (57%) and vitamin (61%) supplementation. Most of the participants (83%) that used PES started using them when they were over 15 years old. The majority of the participants (42%) played rugby as their main high school sport. Conclusion: The findings indicate that there was generally a low prevalence of ergogenic substance use in Johannesburg boys’ high school sport for performance enhancement. Substances such as anabolic androgenic steroids (4%) and growth hormone (5%) were found to be used by the learners. The anti-doping attitude of the learners may be improved by education programmes, which aim to decrease the prevalence of prohibited PES use in adolescent sport.

Better, Stronger, Faster Explaining the Variance Between Professional and Amateur Anti-Doping Policies

Brakeley, August Kashiwa January 2007 (has links)
The world of sport has recently been inundated by stories of doping. These reports are not limited to a select few individuals or sports, but seemingly are spread across sports. At first, it was mostly members of the sports community voicing their discontent, but soon actors outside of the sports community, such as government committees, became interested. Anti-doping policies were created to reduce doping; however, these policies were created independently of government and vary in effectiveness. The most visible variances are between professional and amateur sports. Accordingly, this paper investigates why there is variation between professional and amateur anti-doping policies. This investigation is done in a qualitative fashion and employs the Most Similar System of Design (a comparative method) to identify that factors result in the differences. The paper also contributes to the field by creating and organizing the ethics of doping. Furthermore, it compares the various existing approaches to anti-doping policy by analysing the anti-doping policies of the PGA, IOC, WADA, and the MLB. Subsequently, the paper identifies seven obstacles facing anti-doping regulators and identifies new policy tools that could aid anti-doping policies. Finally, it closes with policy recommendations for the future. This paper is comprehensive: it introduces the topic of anti-doping, the subsequent definitions, explains the ethical considerations, answers why there is variation between professional and amateur anti-doping policies, and provides policy recommendations.

Dependência de exercício físico em academias de ginástica e sua interface com suplementação e imagem corporal / Physical exercise dependence in gym clubs and its interface with supplementation and body image.

Marques, Luciana Rossi 01 October 2014 (has links)
O Brasil é o segundo país no mundo em número de academias de ginástica, contando atualmente com cerca de 30 mil unidades. Apesar da transição no modelo de gestão e filosofia das academias do fitness para o wellness, muitas ainda propagam em seus ambientes o culto ao corpo magro e atlético, dietas sem fundamentação nutricional e consumo descontrolado de suplementos. Crescem as evidências de que uma parcela significativa dos frequentadores de academias desenvolve um comprometimento exacerbado à prática de exercícios físicos, gerando até uma dependência patológica. O objetivo foi determinar a associação entre dependência de exercício físico (DEF), consumo de suplementos e insatisfação da imagem corporal em frequentadores de academias. Para tanto foi empregada a Escala de Comprometimento com Exercício Físico (CEF) em uma amostra de 227 frequentadores, maiores de 19 anos, de ambos os sexo em três academias. Foi realizada entrevista individual com emprego de anamnese nutricional para determinar o perfil de consumo suplementar, avaliação antropométrica, da imagem corporal, do compromisso ao exercício físico assim como de participação na academia. A frequência de DEF nas academias foi de 66% e sendo que as chances estimadas deste ser consumidor de suplementos de 4,53. Os indivíduos dependentes de exercício físico são jovens, com maior chance de pertencer ao sexo masculino, frequentar a academia > 5 vezes por semana, consumir mais de um tipo de suplemento e praticar musculação. A frequência de insatisfação com a imagem corporal foi alta tanto entre homens (50,9%) como mulheres (78,4%). / Brazil is the second country in number of gym clubs, currently with about 30 thousand units. Despite the transition in the managing model and philosophy of gym clubs from fitness to wellness, many still disseminate the cult of a lean and athletic body, diets without nutritional basis, and uncontrolled consumption of supplements. We have growing evidence that a significant number of individuals going to gym clubs develop an exacerbated commitment to the practice of physical exercises, yielding even pathological dependence. The main goal of our work is to determine the association between exercise dependence (ED), supplements consumption, and dissatisfaction with body image between users of gym clubs. For this purpose we employed the Commitment Exercise Scale (CES) in a sample of 227 gym club users, over 19 years old, from both sexes, in three gym clubs. We used nutritional assesment to determine the profile of supplements consumption, and recorded anthropometrical and exercise engagement data. Frequency of ED in gym clubs was estimated to be 66% with odds ratio of 4.53 favoring supplements consumption. Dependent individuals are on average young, most probably males, attending the gym club more than 5 times a week, consumers of more than on type of supplement, and practitioners of body building. Frequency of body image dissatisfaction is high both between men (50.9%) and women (78.4%).
