- Portuguese gym-goers versus performance enhancing substances: what do we know?Publication . Tavares, Ana Sofia; Carolino, Elisabete; Teques, Pedro; Calmeiro, Luís; Serpa, SidónioThe use of prohibited performance-enhancing substances (PES) in gyms is a public health concern due to emerging adverse health effects. While psychological and social factors (intentions, attitudes, and beliefs) influencing PES use are known, understanding reasons for non-use is crucial. Demographic factors like being male, having less education, being unemployed, training frequently, and bodybuilding are linked to PES use. The study aims to identify the profile of gym-goers who do not use PES to distinguish risk characteristics from preventive ones.
- Profile of gym-goers who do not use performance-enhancement substancesPublication . Tavares, Ana Sofia; Carolino, Elisabete; Teques, Pedro; Calmeiro, Luis; Serpa, SidonioIntroduction: Currently the use of prohibited performance-enhancing substances (PES) in fitness and gym settings is a public health concern as adverse health consequences are emerging. Understanding the characteristics of gym-goers who do not use these substances could lead to an important complement to the ongoing research about risk factors for PES use. This study aimed to identify the profile of PES non-use in gym-goers. Methods: In total, 453 gym-goers (mean age = 35.64 years; SD = 13.08 - the measure of central tendency location and measure of absolute dispersion, respectively) completed an online survey assessing sociodemographic factors, exercise characteristics, gym modalities, peers, social influence, attitudes, subjective norms, beliefs, intentions, and self-reported use of PES. Results: Decision Trees showed that being a woman, training less frequently, not practicing bodybuilding, and having a negative intention to consume PES were identified as characteristics of non-users of PES. Discussion: These results may support evidence-based anti-doping interventions to prevent abusive use of PES in the fitness context.
- Protective factors of performance-enhancing substances use in a sample of Portuguese gym-goersPublication . Tavares, Ana Sofia; Carolino, Elisabete; Teques, Pedro; Calmeiro, Luís; Serpa, SidónioBackground: Nowadays, the increased Performance Enhancing-Substance (PES) use in fitness centers is seen as a problematic phenomenon, since it has the potential to grow, and could be seen as an emerging public health and societal concern. Studies focusing on PES use among gym-goers are few and they do not provide information concerning protective factors that justify the refusing intention to use these substances. Understanding the underlying psychosocial mechanisms of PES use and the protective factors of the gym-goers who refuse the use of these substances could help identify those who are most resistant to PES use. Aim: To investigate the protective factors (e.g., sociodemographic factors, exercise profile, gym modalities, peers, social influence, attitudes, subjective norms, beliefs, and intentions) of PES refusing intention in gym-goers. Participants: A convenience sample of 453 Portuguese gym-goers having a mean age of 35.64 (SD=13.08) Tool: Web self-administered questionnaire containing questions related to sociodemographic characteristics and self-reported use of PES, as well as the QAD-Fit based on the Theory of Planned Behavior which is composed by questions grouped on four dimensions (attitudes, beliefs, intentions, and subjective norms). Procedures: Data was collected using an online self-administrated questionnaire, and results were analysed using Decision Trees, which are a method widely used in classifying and identifying profiles, in machine learning and data mining. Results: 88,9% of gym-goers reported the refusal of prohibited PES, showing that being a woman, training less frequently, not practicing bodybuilding, and having a negative intention to consume PES, could be considered protective factors for PES use. Conclusion: Results identifying the protective factors associated with PES refusal intention, which may support public health and clinical interventions to prevent abusive use of PES and improve the health and well-being of gym-goers.
