An innovative way to highlight the power of each polymorphism on elite athletes phenotype expression
2017
The purpose of this study was to determine the probability of soccer players having the best genetic background that could increase performance, evaluating the polymorphism that are considered Performance Enhancing Polymorphism (PEPs) distributed on five genes: PPAR alpha, PPARGC1A, NRF2, ACE e CKMM. Particularly, we investigated how each polymorphism works directly or through another polymorphism to distinguish elite athletes from non-athletic population. Sixty professional soccer players (age 22.5 +/- 2.2) and sixty healthy volunteers (age 21.2 +/- 2.3) were enrolled. Samples of venous blood was used to prepare genomic DNA. The polymorphic sites were scanned using PCR-RFLP protocols with …
Endurance training: Is it bad for you?
2016
Educational aims To illustrate the characteristics of endurance exercise training and its positive effects on health. To provide an overview on the effects of endurance training on airway cells and bronchial reactivity. To summarise the current knowledge on respiratory health problems in elite athletes. Endurance exercise training exerts many positive effects on health, including improved metabolism, reduction of cardiovascular risk, and reduced all-cause and cardiovascular mortality. Intense endurance exercise causes mild epithelial injury and inflammation in the airways, but does not appear to exert detrimental effects on respiratory health or bronchial reactivity in recreational/non-eli…

The individual zones of optimal functioning (IZOF) model (1978–2014): Historical overview of its development and use
2015
The individual zones of optimal functioning (IZOF) model is a sport-specific framework that describes the relationship between emotional experiences and relative success in sporting tasks on the basis of individual rather than group-based patterns. Initially developed by the psychologist Juri Hanin in the 1970s, the number of published studies using the model has since significantly grown and diversified. In an effort to create a comprehensive database of IZOF research and reviews, a literature search was conducted using several databases and existing reference lists. This analysis yielded a total of 183 IZOF-based publications (from 380 compiled). The list of publications was subdivided in…
Effects of Including Sprints in One Weekly Low-Intensity Training Session During the Transition Period of Elite Cyclists
2020
The purpose of this study was to investigate the effects of including 30-s sprints in one weekly low-intensity training (LIT) session during a 3-week transition period in elite cyclists. Sixteen male elite cyclists (maximal oxygen uptake, VO2max: 72 ± 5 ml·kg−1·min−1) reduced their training load by ~60% for 3 weeks from the end of competitive season and performed only LIT or included 30-s sprints (SPR) in one weekly LIT-session. Performance and physiological capacities were evaluated during a prolonged (~2.5 h) test-session, including a strength test, a submaximal blood lactate profile test, an incremental test to exhaustion to determine VO2max, 1 h continuous cycling including four maximal…
ÉTICA DE LA EMPRESA DEPORTIVA: ¿UTOPIA O NECESIDAD?
2020
The modern sport has become a spectacle sport that attracts masses eager for sporting events. In this way, the sport becomes a profitable business capable of generating large economic income that enrich elite athletes, as well as sports businessmen.In this article I propose an ethics of the sports company, as part of the ethics applied to sport, that you see the positive side a commercialization, discarding the negative and that enhances the social responsibility of the sports company in a globalized context.

‘I was excited to train, so I didn’t have problems with the coach’: dual career athletes’ experiences of (dis)empowering motivational climates
2019
In addition to investing in athletic development, adolescent elite athletes are expected to complete their secondary education. As a result of this expectation and the demands of sport and education, they may struggle to sustain high levels of motivation for both domains. Grounded in theoretical tenets of empowering coaching, this study sought to explore student–athletes’ perceptions of empowering and disempowering motivational climates and their possible implications for athletes’ dual career experiences. Semi-structured interviews were conducted with 17 Finnish student–athletes, and the data were thematically analysed. The analysis indicated that a majority of the athletes had experiences…
Stress, Professional Lifestyle, and Telomere Biology in Elite Athletes: A Growing Trend in Psychophysiology of Sport
2020
Professional lifestyle and championship period often put a great deal of pressure on athletes, who usually experience highly stressful periods during training for competitions. Recently, biomarkers of cellular aging, telomere length (TL) and telomerase activity (TA), have been considered to investigate the effects of stress and lifestyle factors. Studies in non-athletic populations have shown that stress and poor lifestyle decrease TL and TA. On the other hand, it has been shown that in general, exercise increases TL and its activity, although the underlying mechanisms remained largely unexplored. TL and TA outcomes in elite athletes remain inconclusive and mainly affected by confounding fa…
The perception of elite athletes’ guided self-reflection and performance in archery
2016
AbstractSelf-reflection has been shown to enhance professional development in clinical, counselling and educational settings. Recent research found that self-reflection can enhance performance in elite sports. The purpose of this intervention study was two-fold: Firstly, to examine whether a guided reflective diary was effective in enhancing accuracy in elite archery, and secondly, to identify factors facilitating and hindering the usage of the guided reflective diary. Eight Singaporean elite archers (four females, four males), aged 20–24 years, reflected on their training using the diary for a period of five weeks. Their pre- and post-intervention performance scores were collected and qual…
