The use of the Vienna Test System in sport psychology research: A review

ABSTRACT

This article seeks to provide a comprehensive review of existing literature relating to the use of the Vienna Test System (VTS) in sport psychology research. A comprehensive search of major databases such as SPORTDiscus, PsycINFO, and Google Scholar yielded 22 studies related to the topic of interest. The results showed that VTS was used to compare athletes and non-athletes, as well as athletes from different sports and levels. It was also used to investigate the effect of certain factors on athlete cognitive performance, to induce ego depletion in athletes, and was shown to be a reliable and valid measure of coordinated motor abilities. The review demonstrates that VTS is a useful objective measure of various psychological constructs, and can be used to complement existing subjective measures in the field. There is great potential in using VTS to provide both researchers and applied sport psychologists with valuable information to aid them in their work with athletes, and future research should aim to identify VTS tests that are relevant to each particular sport.     

Non-targeted metabolomics in sport and exercise science

Metabolomics incorporates the study of metabolites that are produced and released through physiological processes at both the systemic and cellular levels. Biological compounds at the metabolite level are of paramount interest in the sport and exercise sciences, although research in this field has rarely been referred to with the global ‘omics terminology. Commonly studied metabolites in exercise science are notably within cellular pathways for adenosine triphosphate production such as glycolysis (e.g., pyruvate and lactate), β-oxidation of free fatty acids (e.g., palmitate) and ketone bodies (e.g., β-hydroxybutyrate). Non-targeted metabolomic technologies are able to simultaneously analyse the large numbers of metabolites present in human biological samples such as plasma, urine and saliva. These analytical technologies predominately employ nuclear magnetic resonance spectroscopy and chromatography coupled to mass spectrometry. Performing experiments based on non-targeted methods allows for systemic metabolite changes to be analysed and compared to a particular physiological state (e.g., pre-/post-exercise) and provides an opportunity to prospect for metabolite signatures that offer beneficial information for translation into an exercise science context, for both elite performance and public health monitoring. This narrative review provides an introduction to non-targeted metabolomic technologies and discusses current and potential applications in sport and exercise science.     

Choking in sport: a review

Choking under pressure is a pejorative colloquial term (Clark, Tofler, & Lardon, 2005) used to describe a sub-optimal sporting performance under stressful conditions. In order to prevent its occurrence and enable performers to achieve their potential under pressure, a full understanding of the phenomenon is necessary. By reviewing critically the contemporary research, the aim of the paper is to examine the suggested mechanisms and potential moderators of choking in sport, and consider the interventions designed to alleviate it. In addition, the conceptual and methodological concerns that exist within the choking literature will be presented, and directions for future research that address such concerns will be recommended.     

Biomagnetism: a new tool in sport and exercise science

Biomagnetometry is a non-invasive technique for detecting magnetic fields associated with the electrophysiology and magnetic susceptibility of body tissues. The aims of this paper are to provide a review of the discipline of biomagnetism and its measurement using a superconducting quantum interference device (SQUID), and to discuss the potential utility of this technique in sport and exercise science. A tutorial section is presented to provide an introduction to the theory and practical application of SQUID biomagnetometry. A review of the biomagnetism literature demonstrates the variety of previous biomagnetic investigations and suggests several potential applications of biomagnetometry in sport and exercise science. A discussion of these includes an assessment of the advantages of measuring biomagnetic fields as opposed to electrical potentials, with particular reference to the improved precision and accuracy of physiological source modelling using biomagnetic data. There is evidence to suggest that SQUID biomagnetometry would provide useful (and perhaps unique) information on functional, anatomical and physiological assessments in sport and exercise science. Further investigations of biomagnetometry in this discipline should focus on three main areas: cardiology, encephalography and neurology, and body composition assessment.     

The yips in sport: A systematic review

ABSTRACT

The yips are a psycho-neuromuscular movement disorder, which affects sports in which fine motor precision skills are required for success. This review aims to examine key components of the yips within sport literature using a systematic approach. Twenty-five published studies were used in the systematic review, the majority of which focused on the yips in golf (n = 18); case studies were the most popular methodological approach (n = 12). Four components of the yips were identified: psychological, physiological, neurological and performance. This review describes evidence associated with each component according to research design, sample characteristics and main findings. Key findings associated with each component are evaluated and gaps within the existent literature are highlighted. It is concluded that future research incorporates a multi-discipline theory-driven approach on a wider range of sports using a more precise definition of yips types in order to enhance our understanding of the predictors and mechanisms of the yips which, in turn, will allow practitioners to develop effective interventions for athletes.     

Trends and knowledge base in sport and exercise psychology research: a bibliometric review study

Bibliometric methods were used to examine: (1) research themes in sport and exercise psychology articles published between 2008 and 2011; and (2) the intellectual base of the field of sport and exercise psychology, defined as influential literature being cited in these articles. The dataset consisted of 795 articles from five sport and exercise psychology journals and 345 articles obtained through citation-based extension (n = 1140 articles). A cluster analysis yielded 73 clusters showing themes in sport and exercise psychology research. Principal component analysis was used to identify and analyze relationships between 14 highly cited research areas constituting the intellectual base of sport and exercise psychology. Some main findings were: (1) the identification of many re-emerging themes, (2) research related to motivation seems to be extensive, (3) sport psychology and exercise psychology research share theoretical frameworks to some extent, however (4) differences compared to previous reviews indicate that sport psychology and exercise psychology may be regarded as two distinct research fields, rather than one united field, and (5) isolated research areas were identified indicating potential for research integration. Suggestions for future research are provided. The bibliometric approach presented a broad overview of trends and knowledge base in sport and exercise psychology research.     

Estimation versus falsification approaches in sport and exercise science

There has been a recent resurgence in debate about methods for statistical inference in science. The debate addresses statistical concepts and their impact on the value and meaning of analyses’ outcomes. In contrast, philosophical underpinnings of approaches and the extent to which analytical tools match philosophical goals of the scientific method have received less attention. This short piece considers application of the scientific method to “what-is-the-influence-of x-on-y” type questions characteristic of sport and exercise science. We consider applications and interpretations of estimation versus falsification based statistical approaches and their value in addressing how much x influences y, and in measurement error and method agreement settings. We compare estimation using magnitude based inference (MBI) with falsification using null hypothesis significance testing (NHST), and highlight the limited value both of falsification and NHST to address problems in sport and exercise science. We recommend adopting an estimation approach, expressing the uncertainty of effects of x on y, and their practical/clinical value against pre-determined effect magnitudes using MBI.     

Research methods in sport and exercise psychology: quantitative and qualitative issues

Contemporary aspects of research methods in sport and exercise psychology are discussed in this wide-ranging review. After an introduction centred on trends in sport and exercise psychology methods, the review is organized around the major themes of quantitative and qualitative research. Our aim is to highlight areas that may be problematic or controversial (e.g. stepwise statistical procedures), underused (e.g. discriminant analysis), increasingly used (e.g. meta-analysis, structural equation modelling, qualitative content analysis) and emergent (e.g. realist tales of writing). Perspectives range from the technical and speculative to the controversial and critical. While deliberately not providing a 'cookbook' approach to research methods, we hope to provide enough material to help researchers to appreciate the diversity of potential methods and to adopt a more critical perspective in their own research consumption and production.     

Perspectives of applied collaborative sport science research within professional team sports

The purpose of the study was to examine the perspectives of both academics and practitioners in relation to forming applied collaborative sport science research within team sports. Ninety-three participants who had previously engaged in collaborative research partnerships within team sports completed an online survey which focused on motivations and barriers for forming collaborations using blinded sliding scale (0–100) and rank order list. Research collaborations were mainly formed to improve the team performance (Academic: 73.6?±?23.3; Practitioner: 84.3?±?16.0; effect size (ES?=?0.54), small). Academics ranked journal articles’ importance significantly higher than practitioners did (Academic: M_rank?=?53.9; Practitioner: 36.0; z?=??3.18, p?=?.001, p?q). However, practitioners rated one-to-one communication as more preferential (Academic: M_rank?=?41.3; Practitioner 56.1; z?=??2.62, p?=?.009, p?q). Some potential barriers were found in terms of staff buy in (Academic: 70.0?±?25.5; Practitioner: 56.8?±?27.3; ES?=?0.50, small) and funding (Academic: 68.0?±?24.9; Practitioner: 67.5?±?28.0; ES?=?0.02, trivial). Both groups revealed low motivation for invasive mechanistic research (Academic: 36.3?±?24.2; Practitioner: 36.4?±?27.5; ES?=?0.01, trivial), with practitioners have a preference towards ‘fast’ type research. There was a general agreement between academics and practitioners for forming research collaborations. Some potential barriers still exist (e.g. staff buy in and funding), with practitioners preferring ‘fast’ informal research dissemination compared to the ‘slow’ quality control approach of academics.     

Underrepresentation of women in sport leadership: A review of research

Despite increased participation opportunities for girls and women in sport, they are underrepresented in leadership positions at all levels of sport. The objective of this review is to provide a multilevel examination of available scholarship that contributes to understanding why there are so few women in leadership positions within sport. From a macro-level perspective, scholarship regarding the institutionalized practices of gender in sport is examined. The meso-level review includes stereotyping of leaders, issues of discrimination, and gendered organizational cultures. Finally research reviewed at the micro-level explores women's expectations in leadership positions, occupational turnover intentions, and the influence of symbolic interactionism on women's career advancement. In addition, the author identifies new research areas and additional recommendations for how best to increase the number of women in leadership positions in sport.     

Personality in sport: a comprehensive review

This review addresses personality in organised sport. We describe the extant literature that has explored personality effects on athletic success and population-based differences before hypothesising how sport participation may contribute to personality development. We then outline the role of personality in athletic interactions and group processes before considering the practical applications of personality research and avenues for future study. Our review shows that personality is an important determinant of long-term success in sport and identifies clear personality differences between individuals that participate in organised sport and individuals that do not participate in organised sport. We also observe important personality differences between sub-samples of athletes and outline the contribution of personality to intragroup relationships and team effectiveness in team sport. The interaction of genetic and environmental influences is presented as a promising avenue of inquiry that can strengthen our understanding of personality effects on sport and exercise participation and athletic success. We conclude by outlining implications for applied sport psychology.     

Proposing application of results in sport and exercise research reports

The application of sport and exercise research findings to practice requires careful interpretation and integration of evidence. This paper reviews principles of evidence-based practice and the application of research in sports and exercise, in order to provide recommendations on developing appropriate application sections in research reports for sport and exercise journals. The strength of recommendations for application fall into one of four levels, with potential applications qualified as strong, limited, preliminary, or hypothesized. Specific limitations that should be discussed in framing recommendations for practice are also noted for each of these levels that should be useful for authors, and for practitioners and clinicians in interpreting these recommendations.
