Yellow and social perceptions of racing cyclists’ sportspersonship: Proposing an inter-contextual analysis

2016

Through inter-contextual designs, the present set of experiments sought to explore whether the colour yellow would impact on social perceptions of sportspersonship exclusively in relation to competitive cycling. In Experiment 1 (N = 149), a silhouette image of a cyclist on a yellow background yielded lower perceptions of sportspersonship in comparison to grey or to the context of motocross, regardless of the colour. That interaction was conceptually replicated in Experiment 2 (N = 146) while changing measures (i.e., adaptation of the World Anti-Doping Code) and the context of comparison to sprinting. Furthermore, female and male observers' scores did not differ significantly thereby suggest…

Identification of Factors Associated with Potential Doping Behavior in Sports: A Cross-Sectional Analysis in High-Level Competitive Swimmers

2018

Background: Doping behavior, including the misuse of performance-enhancing drugs, is currently a serious problem in sports, and the efficacy of preventive efforts directly depends on information regarding the associations among different precipitating factors (PF) and doping behavior. This study aimed to establish the PF of potential doping behavior (PDB) in competitive swimmers. Methods: The study included 301 swimmers from Slovenia (153 females, 16.4 &plusmn

Physical and cognitive doping in university students using the unrelated question model (UQM): Assessing the influence of the probability of receivin…

2018

Study objectives: In order to increase the value of randomized response techniques (RRTs) as tools for studying sensitive issues, the present study investigated whether the prevalence estimate for a sensitive item π̂$_{s}$ assessed with the unrelated questionnaire method (UQM) is influenced by changing the probability of receiving the sensitive question p. Material and methods: A short paper-and-pencil questionnaire was distributed to 1.243 university students assessing the 12-month prevalence of physical and cognitive doping using two versions of the UQM with different probabilities for receiving the sensitive question (p ≈ 1/3 and p ≈ 2/3). Likelihood ratio tests were used to assess wheth…

Randomized response estimates for doping and illicit drug use in elite athletes.

2008

Abstract Background To date, there are estimates for the percentage of unknown cases of doping and illicit drug use in fitness sports, but not for elite sports. This can be attributed to the problem of implementing questionnaires and surveys to get reliable epidemiological estimates of deviant or illicit behaviour. Methods All athletes questioned were subject to doping controls as members or junior members of the national teams. In order to estimate the prevalence of doping and illicit drug abuse, the athletes were either issued an anonymous standardized questionnaire (SQ; n  = 1394) or were interviewed using randomized response technique (RRT; n  = 480). We used a two-sided z -test to comp…

Fitter, healthier and stronger? Many factors influence elite athletes' long-term health.

2020

It is now incontrovertible that properly tailored exercise therapy increases physical fitness, reduces depression, lowers cardiometabolic risk factors, reduces pain and improves health-related quality of life in chronically ill patients. Former elite athletes usually exercise more than population controls during their later life. Participating in elite endurance-type sports—an indicator of exceptionally high aerobic fitness—is associated with low risk of premature death, at least before the use of doping became common.1 2 Athlete mortality statistics are often compared with data from the general population. Finnish male former elite athletes outlived matched controls who were healthy at the…

Current limitations of the Athlete's Biological Passport use in sports.

2011

The Athletes Biological Passport (ABP) has received both criticisms and support during this year. In a recent issue of The Lancet, Michael Wozny considered that the use of the ABP makes it more difficult to take banned substances and that it was successfully used against the Italian elite cyclist Franco Pellizotti. After that, Italy's anti-doping tribunal considered that there was not enough evidence to prove manipulation of his own blood profile in Pellizotti's case. However, the UCI appealed to the Court of Arbitration for Sport (CAS) that sanctioned Pellizotti with a suspension of 2 years. Since its implementation, some problems have emerged. From 2010 to date, a large number of reports …

Toward Prevention of Doping in Youth Sport: Cross-Sectional Analysis of Correlates of Doping Tendency in Swimming.

2019

Doping is recognized as one of the most important problems in sports, but a limited number of studies have investigated doping problems in youth athletes. This study aimed to evaluate doping tendency (potential doping behavior (PDB)) and correlates of PDB in youth age swimmers. The participants were 241 competitive swimmers (131 females

Is unintentional doping real, or just an excuse?

2017

Although some athletes who engage in doping do so willingly in order to gain an unfair advantage (ie, ‘to cheat’), the possibility of athletes doping inadvertently or unintentionally cannot be discounted. In this article, we aim to address common misconceptions of the notion of ‘unintentional doping’, and discuss this topic with reference to statistics, reports and recommendations (eg, anti-doping codes) produced by the World Anti-Doping Agency (WADA), together with evidence from recent empirical research. Unintentional doping (also known as ‘inadvertent’ or ‘accidental’ doping) refers to the accidental consumption of performance-enhancing substances included on WADA’s banned list.1 It ofte…

Antidoping Science

2018

The ineffectiveness of antidoping programs in elite sport, largely due to human and political factors, is leading to a new resolve and greater transparency of antidoping authorities and those stakeholders interested in drug-free sport. The perception by the public, athletes, and the World Anti-Doping Agency (WADA) of antidoping science and current drug testing programs in elite sport varies widely from "ineffective" to "robust and reliable." Here, we discuss why a careful and considered reevaluation of the underlying premise of antidoping science is needed to bring this unique application of predictive/diagnostic science more in line with other areas of medicine. We show how the validity of…

Micellar liquid chromatography in doping control.

2010

The issue of doping control in sport involves the development of reliable analytical procedures and efficient strategies to process a large number of samples in a short period of time. Reversed-phase LC techniques with aqueous–organic mobile phases and MS or diode-array detection yield satisfactory results for the identification of prohibited substances in sport. However, time-consuming sample pretreatment steps are required, which reduces sample throughput. Micellar LC (MLC) that uses hybrid mobile phases of surfactant above its critical micellar concentration and organic solvent has been revealed as an interesting alternative. The surfactant sodium dodecyl sulfate solubilizes the protein…
