#1
James R J Greenfield, Haram Francis Hwang, Claire Davies, Andrew J McDaid
Ligaments within the human knee are commonly torn or injured as a result of sports that involve sharp direction changes, pivoting and landing. For this reason, athletes are often side-lined from their respective sports for up to 18 months after injury to rehabilitate. As part of the rehabilitation process, knee braces are often prescribed in an attempt to decrease the recovery period of the injured individual by restraining and minimizing the motion at the knee. However, the true efficacy of knee bracing is yet to be fully evaluated as studies show mixed results to whether braces actually decrease the rehabilitation period for patients...

REVIEW
Urban Johnson, Andreas Ivarsson
This review provides an overview of recent theoretical and empirical developments regarding psychosocial factors related to the prediction and prevention of sport injuries, and highlights some of the most interesting areas of investigation that have been carried out in the past few years. For instance, a systematic review of the most cited and used theoretical framework in the field has recently been performed, which supports the model's suggestion that psychosocial variables, as well as psychologically based interventions, can influence injury risk among athletes...

Todd M Loughead
Athlete leadership is defined as an athlete who occupies a formal or informal leadership role within a team and influences team members to achieve a common objective. The area of athlete leadership has been shaped by theories and measurement tools from organizational and sport coaching literatures. The present article describes the conceptual developments within athlete leadership by providing an operational definition of this construct, followed by the theories and measurement tools used to examine athlete leadership...

REVIEW
Rebecca Lewthwaite, Gabriele Wulf
We review three lines of recent research at an intersection of motor learning and sport psychology as they relate to motor skill acquisition: enhanced expectancies, autonomy support, and external attentional focus. Findings within these lines of research have been integrated into a new theory, the OPTIMAL (Optimizing Performance through Intrinsic Motivation and Attention for Learning) theory (i.e., OPTIMAL theory, Wulf and Lewthwaite, 2016), and have been applied in motor skill acquisition and performance. Implications range from more effective skill development in children and novice performers to athletes and performers in many fields, including clinical rehabilitation...

The development of elite, high performance athletes reflects the complex interaction of biological and genetic factors with important environmental influences. Over the past two decades, discussions of athlete development have largely focused on the role of 'deliberate' practice, and more recently, researchers have begun exploring the means by which practice can be best used to maximize the rate of talent development across the different stages of athlete development. In this article, we summarize recent developments in understanding how athletes maximize practice including (a) antecedents of practice involvement, (b) environmental constraints of practice involvement, (c) the value of diversification for athlete development, (d) and methodological advancements in this area...

Zella E Moore, Kehana Bonagura
Clinical sport psychology (CSP) is a contemporary, empirically informed model that employs a scope, style, and mode of practice built upon cutting-edge findings from both clinical and sport sciences, and that follows the sound methodological traditions of clinical psychology [1(••)]. Conceptualizing athletic performance and well-being through the context of empirical research in both athletic and nonathletic domains of functioning, CSP practice can involve the enhancement of athletic performance, and also the personal development and psychological well-being of performers...

#7
REVIEW
Christopher Mesagno, Juergen Beckmann
In sport, choking under pressure is a major concern for athletes, coaches and sport psychologists because athletes fail to meet self-imposed performance expectations in critical situations (when it counts the most), which is devastating and embarrassing. Researchers have debated choking under pressure definitions, identified personality characteristics that exacerbate choking outcomes, and examined models to determine mechanisms for choking. Based on these investigations, several interventions to prevent choking have been developed and tested...

REVIEW
Sophia Jowett
Coaching has been often viewed as a context within which coaches operate to largely bring about changes in athlete's performance and wellbeing. One key factor to successful outcomes in coaching is the quality of the relationship between coaches and athletes. In this article, I propose that the coach-athlete relationship is at the heart of coaching. Moreover, the aim is to describe and explain how the quality of the relationship coaches and athletes develop and maintain over the course of their sporting partnership alongside coaches and athletes' knowledge and outcomes, form a system that is capable of defining coaching effectiveness and success...

The field of sport psychology is dynamic and growing. To continue building credibility with the public and allied professionals, effective and ethical practice is crucial. Advances in technology have allowed sport psychology professionals to consult with athletes from a distance, but practitioners must be mindful of their competency to use technology, confidentiality concerns, and the suitability of technology for their clients. Movement toward defining competency and clarifying issues of title usage are additional areas in which the field is gaining momentum...

Applied sport psychology practice and research date back to the late 19th century. During this period investigators have largely examined the interventions practitioners employ to help athletes. More recently, researchers have begun addressing the person employing those interventions, including identifying their attributes and how they develop expertise, in recognition that practitioners are central to effective practice. Research focused on practitioners can inform educational and registration pathways, helping trainees to develop the knowledge, skills, and characteristics needed to meet their clients' needs...

INTRODUCTION: Energy drinks (EDs) have become an integral part of the young adult, athletic, and military culture. Many athletes are convinced that EDs enhance performance, and service members as well as college students frequently use EDs as stimulants to counter sleep deprivation, or to improve academic performance. However, concerns have been raised by some military leaders about potential adverse effects of EDs. MATERIALS AND METHODS: A needs assessment survey of a convenience sample of military health care providers was conducted and identified EDs as a top knowledge need for those providers working in the area of traumatic brain injury (TBI)...

Amino acids playing important roles in metabolic processes are often included in dietary supplements whose use has largely expanded over the last 20 years not only in patients with particular deficiencies, but also in athletes and even common people that want to enrich their regular daily diet. In the present study, a bare silica Kinetex core-shell 2.6μm HILIC column was used for separation of some important hydrophilic amino acids and amino acids-like molecules i.e., aspartic acid, creatine, carnitine, arginine and the tripeptide glutathione (GSH), by optimizing the chromatographic conditions for their determination in complex alimentary supplements...

Higenamine is a key component of traditional Chinese herbal medicine. The fruit of Nandina domestica (which contains this component) is available as an ingredient in the so-called Nanten-nodo-ame throat lozenge found on the Japanese market, which is an over-the-counter pharmaceutical and is easy to purchase for Japanese athletes. However, higenamine is a non-selective β2-agonist, which is exemplified in the prohibited list of the World Anti-Doping Agency (WADA). Therefore, some have raised a concern regarding the potential cause of increased unintentional higenamine doping cases in the Asian region...

Safe performance limits of soldiers and athletes have typically relied on predictive work-rest models of ambient conditions, average work intensity, and characteristics of the population. Bioengineering advances in noninvasive sensor technologies including miniaturization, reduced cost, power requirements, and comfort now make it possible to produce individual predictions of safe thermal-work limits. These precision medicine assessments depend on the development of thoughtful algorithms based on physics and physiology...

Sudden cardiac death (SCD) is a sudden and unexpected death caused by loss of heart of function. SCD may occur in any population, but when it occurs on the playing field in a young individual, communities worldwide are affected. Although these events are rare, media coverage of sudden cardiac arrests in young athletes have created the impression that these events are far more common than they appear. With a heightened awareness of SCD in young athletes, screening methods have been developed to try and prevent these events from occurring...

There are several sets of guidelines recommending sports participation for patients with bleeding disorders. Though there is a perceived risk of injury and the associated bleeding complications, several studies have been done in this patient population and have found no increased risk. In addition, there are many other benefits to participation including improvement in physical fitness status, better health outcomes, improvement in quality of life, and the development of increased flexibility, gait coordination, and muscular strength, which may actually reduce the risk of subsequent injury...
