PURPOSE/HYPOTHESIS: The purpose of this observational study was to determine which factors, including sex, are associated with increased rotatory knee laxity in collegiate athletes with no history of knee injuries. It was hypothesized that increased rotatory knee laxity, measured by a quantitative pivot shift test, would correlate with female sex, increased anterior translation during the Lachman test, generalized ligamentous laxity, and knee hyperextension. METHODS: Ninety-eight collegiate athletes with a median age of 20 (range 18-25) years with no history of knee injuries were tested...

INTRODUCTION: Currently there are no data examining the impact of exercise on the perception of time which is surprising as optimal competitive performance is dependent on accurate pacing using knowledge of time elapsed. METHODS: With institutional ethics approval, 12 recreationally active adult participants (f=7, m=5) undertook both 30s Wingate cycles and 20min (1200s) rowing ergometer bouts as short and long duration self-paced exercise trials, in each of three conditions on separate occasions: 1) light exertion: RPE 11, 2) heavy exertion: RPE 15, 3) maximal exertion: RPE 20...

Tests of handgrip strength (HGS) and handgrip force (HGF) are commonly used across a number of sporting populations. Measures of HGS and HGF have also been utilized by practitioners and researchers to evaluate links with sports performance. This article, firstly evaluates the validity and reliability of various handgrip dynamometers (HGD) and HGF sensors, providing recommendations for procedures to ensure precise and reliable data are collected as part of an athlete testing battery. Secondly, the differences in HGS between elite and sub-elite athletes and the relationships between HGS, HGF, and sports performance are discussed...

BACKGROUND: The natural history of femoroacetabular impingement (FAI) remains incompletely understood. In particular, there is limited documentation of joint damage in adolescent patients with limited range of motion (LROM) of the hip, which is commonly associated with FAI. PURPOSE: To evaluate changes in magnetic resonance imaging (MRI), radiographs, and clinical examinations over 5 years in a group of athletes from a wide variety of sports with asymptomatic LROM of the hip compared with matched controls...

For sea level-based endurance athletes who compete at moderate and high altitudes, many are not logistically able to arrive at altitude weeks prior to the event to fully acclimatize. For those who can only arrive at altitude the night before competition, we asked if there is a physiological and performance advantage in reducing altitude exposure time to two hours prior to competition. On three separate visits, ten cyclists completed overnight laboratory exposures of: 1) a 14-hour exposure to normobaric hypoxia (16...

The ratio of the lengths of the second and fourth digits (2D:4D) has been described as reflecting endogenous prenatal androgen exposure. In general, 2D:4D is lower in men than in women and has potential as a biomarker or predictor for various diseases, athletic ability, and academic performance. Dupuytren disease has digital flexion contractures and is known to predominate in men, but the pathogenesis of the disease remains unclear. To clarify the relationships between Dupuytren disease and endogenous androgens, we performed a retrospective analysis of hand radiographs to investigate 2D:4D in Dupuytren disease...

During the last decade, team confidence has received more and more attention in the sport psychology literature. Research has demonstrated that athletes who are more confident in their team's abilities exert more effort, set more challenging goals, are more resilient when facing adversities, and ultimately perform better. This article reviews the existing literature in order to provide more clarity in terms of the conceptualization and the operationalization of team confidence. We thereby distinguish between collective efficacy (i...

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...

REVIEW
Christian Swann, Lee Crust, Stewart A Vella
Csikszentmihalyi's conceptualisation of flow is the primary framework for understanding the psychology of optimal experience and performance in sport. However, emerging evidence suggests a more dynamic, multi-state perspective. This review focuses primarily on recent studies highlighting a second, overlapping 'clutch' state which - in addition to flow - underlies optimal performance in sport. We also examine how the nature of goals ('open' or 'fixed') athletes pursue influence the experience of flow and clutch respectively...

REVIEW

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...

REVIEW
Joseph Baker, Bradley W Young, David Mann
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...

In this review paper, we provide an overview of recent research on prosocial and antisocial behaviors, in the context of sport, focusing mainly on antecedents and consequences of these behaviors. Motivational variables such as task orientation, mastery climate, autonomous motivation, and autonomy supportive climate are likely to promote prosocial behavior, whereas ego orientation, performance climate, controlled motivation, and controlling climate may lead to antisocial behavior. The effects of some motivational variables (i...

Since mindfulness-based and acceptance-based practice models were first conceptualized and applied in sport in an attempt to enhance performance and overall well-being of athletes and performers, these state-of-the-art theoretical and practice models have substantially broadened our knowledge base and have been successfully incorporated into sport and performance practice domains worldwide. Evolving from a sound empirical foundation, mindfulness-based and acceptance-based models in sport psychology have accumulated a strong basic and applied empirical foundation...

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...

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...

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 incentives for sport organizations to identify talented athletes from a young age continue to grow, yet effective talent identification remains a challenging task. This opinion paper examines recent advances in talent identification, focusing in particular on the emergence of new approaches that may offer promise to identify talent (e.g., small-sided games, genetic testing, and advanced statistical analyses). We appraise new multi-disciplinary and large-scale population studies of talent identification, provide a consideration of the most recent psychological predictors of performance, examine the emergence of new approaches that strive to diminish biases in talent identification, and look at the rise in interest in talent identification in Paralympic sport...

Despite a long standing assertion that sociocultural domain is one of the factors constituting human psychological phenomena, sport psychological science has only recently begun to examine culture as the principal basis of physical activity and sport participants' behaviour, wellbeing, engagement, and performance outcomes. Emphasizing the centrality of culture in bringing meaning to athlete careers and life projects, I summarise empirical literature explicitly positioned within cultural sport psychology (CSP)...
