Genetics and Sports

Description

This second edition of Genetics and Sports expands on topics previously discussed in an attempt to create an integrated and holistic understanding of the field of sports genomics. It is an update on technologies and on the role of genetics in training, performance, injury, and other exercise-related phenotypes. Ethical concerns and the importance of counselling before and after genetic testing are also addressed. It is increasingly important to understand the field of genetics and sports because of the potential to use and misuse information. All exercise scientists, sport and exercise clinicians, athletes, and coaches need to be adequately informed to ensure that genetic information is accurately and properly used. Genetics and Sports is, therefore, highly recommended to all of these groups.

Preface
The first edition of this book, Genetics and Sport , covered a number of topics in an attempt to obtain an integrated and holistic understanding of the field of sports and exercise genomics. Since the publication of the original edition in 2009, research in the field of genomics has continued to increase exponentially. Most notably, as the cost of whole-genome screening technology has become more affordable, we have seen a rise in the amount of genome-wide association studies. Other new technologies, such as copy number variants, next-generation sequencing technologies and epigenetic profiling, have further highlighted the complexities of trying to decipher exactly how the human genome regulates interindividual variation in athletic performance, response to training and susceptibility to injury as well as exercise-associated illnesses. Specific to the field of sports and exercise medicine, these technologies have only just started to contribute to our understanding of the interindividual differences in these traits (phenotypes). This book, the second edition in the series Genetics and Sport , provides an update on recent developments within the field.
The introductory chapter outlines the basic methodologies of genetic association studies and discusses the technological advances in genomics. Noteworthy advances include an increased appreciation for the potential role of the epigenome in performance and injury. This is followed by an update in the often misunderstood debate of nature (genetics) versus nurture (common environmental effects such as training, diet, etc.) in determining athletic ability. This chapter explains how the environment interacts with the genome and how the traditional argument of nature versus nurture has become irrelevant as our knowledge advances.
When discussing the genetics of athletic performance, it is important to consider that in addition to outcomes of performance, adaptation to training is also an extremely important phenotype which will translate to improved performance within an athlete. The following chapter reviews the recent advances in the genetics of exercise training adaptation. Despite a large amount of recent research, including further high-quality genome-wide approaches, such as the recent study produced from the HERITAGE cohort, the identification of genetic factors underlying the adaptations of various traits to exercise training remains unmet and elusive. Perhaps future mRNA transcriptome and epigenetic work may prove why discovering repeatable genetic factors has been so challenging. Conclusions within the chapter reviewing the advances in the genetics of performance are very similar. Several genetic markers (155 to be exact) have been identified to date; however, the association of the majority of these markers has not been replicated (approx. 80%) in independent samples, raising the possibility that many of these markers may be the product of false-positive findings. As the next chapter on the future of genomic research describes, a future effort to elucidate the genetic contribution to both performance and adaptation to training requires large, multicentre collaborative projects with sound experimental designs.
There is now mounting evidence that genetics plays an important role in both sport injury predisposition and other sports-related phenotypes. The evidence is reviewed within two subsequent chapters. Initially, the studies identifying genetic risk factors for musculoskeletal soft-tissue injuries are discussed. Since the genes associated with injury code for structural and/or regulatory components of musculoskeletal soft tissue, it is likely that these genetic variants affect the tissue mechanics. Thus, the subsequent chapter further reviews the genetics of other exercise-related phenotypes which also affect changes in tissue mechanical properties.
The final chapter discusses the practical and ethical considerations regarding genetic tests to predict performance and/or risk of exercise-related injury or illness. It is important that scientists and practitioners understand the limitations of the available genetic tests, as well as the ethical concerns and importance of counselling before and after genetic testing.
