Student-athletes who strive for success in high level sports while pursuing upper secondary education may be prone to sport and school burnout. The present study examined the co-developmental dynamic of sport and school burnout in Finnish adolescent student-athletes (N time 1 = 391; N time 2 = 373) across the first year of upper secondary school by using cross-lagged structural equation modeling (SEM). Furthermore, we used sport and school-related achievement goals as predictors of sport and school burnout, namely, sport and school-related exhaustion, cynicism, and feelings of inadequacy...

REVIEW
Terrance A Sgroi, John M Zajac
PURPOSE OF REVIEW: Throwing places high demands on the human body, and specific characteristics are developed over time unique to these athletes. When returning to throw after injury, it is important to follow a criterion-based progression that allows the body to be prepared appropriately for the stresses that throwing will require. There is currently a void in the literature for criteria-based progression that helps these athletes return to the highest level of play. RECENT FINDINGS: As injury rates continue to rise in baseball, there is increased evidence showing contributions of the core and lower extremity to the baseball pitch...

BACKGROUND: Achilles tendon insertional sleeve avulsions occur when the Achilles distal tendon sleeve ruptures off of its insertion into the calcaneal tuberosity, sometimes with a small bony fragment from calcific tendinosis. Little evidence exists describing the outcomes and rerupture rate after operative management of Achilles tendon sleeve avulsions. METHODS: A retrospective chart review was performed to identify patients who sustained an Achilles sleeve avulsion injury treated with operative repair between October 2005 and July 2014...

The ability of athletes to train day after day depends in large part on adequate restoration of muscle glycogen stores, a process that requires the consumption of sufficient dietary carbohydrates and ample time. Providing effective guidance to athletes and others wishing to enhance training adaptations and improve performance requires an understanding of the normal variations in muscle glycogen content in response to training and diet; the time required for adequate restoration of glycogen stores; the influence of the amount, type, and timing of carbohydrate intake on glycogen resynthesis; and the impact of other nutrients on glycogenesis...

The term doping is generally used to indicate practices based on the use of performance-enhancing drugs (PEDs) or the abuse of medical therapies. Mostly analysed by doctors and officials, doping nevertheless also requires a philosophical consideration to avoid being simplistically portrayed as an isolated practice. To do this, we need to pay attention to the contradictions and paradoxes in the modern approach to doping in sport. In this context, doping is not only relevant to the health of an individual involved in the violation of World Anti-Doping Agency (WADA) criteria, but it actually represents a double-edged phenomenon containing ethical and legal points of view...

For "The Year That Was 2017," I have selected 3 papers in the area of growth, maturation, and exercise during youth. The first paper has been chosen because it provides for the first time the relative age, maturation, and anthropometric biases on position allocation in elite youth soccer players participating in talent identification programs in professional soccer league. Specific anthropometrical attributes characterized playing positions with a bias toward these athletes who are comparatively tall and heavy for their age already in younger ages, whereas position-specific physical attributes do not become apparent until the later stages of talent development...

BACKGROUND:  Osteitis pubis is a common cause of chronic groin pain. Due to high clinical uncertainty and varying etiopathology, the diagnosis is often delayed. Especially athletes suffer from this disease, but patients with orthopaedic, traumatological, neurological, urological, gynaecological, and rheumatic complaints can also be affected. Osteitis pubis can be treated by conservative as well as surgical techniques. MATERIAL AND METHODS:  Systematic literature research, descriptive presentation of the studies, and interpretation of evidence-based medicine results...

Background: Competitive athletes train body and mind in preparation for competition with mental fortitude often providing the "winning edge." Similarly, the current-day warfighter faces significant physical and psychological challenges and must be prepared to respond to life-threatening danger with mental and physical agility. Sport Psychology for the Soldier Athlete recognizes the soldier as an elite athlete and provides training required to perform at the highest caliber. Through this curriculum, mental skills coaching in goal setting, imagery, positive self-talk, and heart rate control is integrated into routine physical fitness training...

In 2017, considerable attention has been paid by researchers on early sports specialization for youth athletes. Issues related to injury, burnout, and talent development to name a few have been debated, particularly when contrasted against other opposing youth development approaches, such as a multisport approach. The increasing professionalization of young athletes, a particular concern of this author, is coupled with the ensuing physical and mental pressures on these youngsters, as highlighted by the 2 highlighted publications in this commentary...

Professional society recommendations to decrease sudden cardiac death in athletes, including eligibility requirements with disqualification for athletes with diagnosed disease as well as preparticipation screening and emergency preparedness, were updated in 2015. The update includes new sections on aortic disease, channelopathies, and sickle cell trait, as well as a change in format from the previous binary yes/no format to the more nuanced and contemporary "class and level of evidence" format. Eighty-four of the 246 recommendations now carry Class II designation-"reasonable," or "may be considered...

The aim of this study was to define a method for evaluating a player's decisions during a game based on the success probability of his actions and for analyzing the player strategy inferred from game actions. There were developed formal definitions of i) the stochastic process of player decisions in game situations and ii) the inference process of player strategy based on his game decisions. The method was applied to the context of soccer goalkeepers. A model of goalkeeper positioning, with geometric parameters and solutions to optimize his position based on the ball position and trajectory, was developed...

BACKGROUND: Anatomic findings on MRI scans of the shoulder likely affect patients differently based on their physical demands and fitness levels. The natural history of these anatomic findings once professional overhead athletes retire remains unclear. A better understanding of what happens with these findings after retirement may influence how we manage shoulder problems in athletes. PURPOSE: (1) What is the natural history of MRI-observed findings in the throwing and nonthrowing shoulders of professional European handball players after retirement from the sport? What proportion of these individuals have diagnosable findings on MRI, and do these findings disappear after retirement? (2) Do clinical findings such as Constant and Murley score and shoulder ROM change after retirement in these professional overhead athletes? METHODS: The inception cohort of this series consisted of the entire Swiss National European handball team except the goalkeepers...

The study aimed to identify the influence of prior knowledge of exercise duration associated with initial information about momentary match status (losing or winning) on the pacing behaviour displayed during soccer game-based activities. Twenty semi-professional male players participated in four game scenarios divided in two sessions. In the first game scenario, players were not informed about the time duration or initial match status. In the second, players were only informed they would be required to play a small-sided game for 12 minutes...

The functional RR genotype of the alpha-actinin-3 (ACTN3) gene has been reported to be associated with elite sprint/power athlete status. Although large and rapidly increasing number of studies have investigated the associations between the ACTN3 genotypes and athletic performance in various sport disciplines, there is a lack of studies on the genetic predisposition in Sport Climbing, which was selected to be part of the next Summer Olympic Games in Tokyo 2020 with three subdisciplines ('Lead Climbing', 'Speed Climbing' and 'Bouldering')...

Elite soccer players (~15 yr) from professional academies in the UK were rated on technical, tactical, physical and creative skills by coaches at time 1 (T1). Players estimated accumulated hours in soccer practice (coach-led activities) and play (self-led activities) during childhood. Coach-ratings were again collected 2.5 yr later (T2) for players that received a professional contract (~17 yr). Adult-professional status was determined at T3 (~ 20 yr). Skill ratings distinguished across the three "future" groups (academy-only, youth-professional only and adult-professional), for all but creative skill...

Background: Little is known about career length after anterior cruciate ligament (ACL) reconstruction in Major League Soccer (MLS), the top men's professional soccer league in the United States. Further, it is unspecified whether athletes returning to soccer after ACL reconstruction are at a higher risk for injuries, beyond new knee injuries. Purpose: To examine career length and the incidence of lower extremity injuries in MLS athletes after ACL reconstruction in comparison with age-matched controls...
