REVIEW
Yuka Nakajima
An increasing number of teachers are introducing animals into their class so that pupils foster cognitive, physiological, and social skills through their interaction with animals. Along with such an educational style termed animal-assisted education (AAE), Japanese formal education has also utilized animals for education. Japanese animal-rearing education is unique regarding the following two points: (1) it takes the form of "education through assisting animals" rather than "animals assisting education" and (2) animal rearing is embedded in formal education...

Regular, low-intensity physical activity is currently advocated for lowering the risk of developing many acute and especially chronic diseases. However, several lines of evidence attest that strenuous exercise may enhance inflammation and trigger the generation of free radical-mediated damage, thus overwhelming the undisputable benefits of regular, medium-intensity physical activity. Since reactive oxygen species are actively generated during high-intensity exercise, and these reactive compounds are known to impact DNA stability, we review here the current evidence about strenuous exercise and DNA injury...

Pacing has been characterized as a multi-faceted goal-directed process of decision-making in which athletes need to decide how and when to invest their energy during the race, a process essential for optimal performance. Both physiological as well as psychological characteristics associated with adequate pacing and performance are known to develop with age. Consequently, the multi-faceted skill of pacing might be under construction throughout adolescence as well. Therefore, we propose that the complex skill of pacing is a potential important performance characteristic for talented youth athletes, that needs to be developed throughout adolescence...

Engaging in competitive sports as a youth can have many health benefits, but recent studies also report a high risk for injury. The long-term purpose of this Swedish research program is to develop a framework for safe track and field training for young athletes (aged 12-15 years). The aim of this study was to establish what is perceived to contribute and cause injuries in youth track and field by compiling the best available experiential knowledge about the underlying factors and use this knowledge to identify appropriate areas to handle these in practical ways...

INTRODUCTION: In 2014, 60 million youth ages 6-18 participated in some form of generalized athletics. 3.5 million children are injured annually participating in organized sport or recreational activities. While sound physical education can decrease the burden of youth sports injuries, the median annual physical education budget of $764 for United States elementary, middle and high schools may not allow enough flexibility to apply evidenced-based guidelines. EVIDENCE ACQUISITION: The topics were selected after a careful review of the 2016 National Strength and Conditioning Association Position Statement on Long-Term Athletic Development...

Long-term training leads experts to develop a focused and efficient organization of task-related neural networks. "Neural efficiency" hypothesis posits that neural activity is reduced in experts. Here we tested the following working hypotheses: compared to non-athletes, athletes showed lower cortical activation in task-sensitive brain areas during the processing of sports related and sports unrelated visuo-spatial tasks. To address this issue, cortical activation was examined with fMRI in 14 table tennis athletes and 14 non-athletes while performing the visuo-spatial tasks...

Low-carbohydrate-high-fat (LCHF) diets have been used as a means of weight loss and control of symptoms in several clinical conditions. There is emerging evidence that the metabolic changes induced by LCHF diets enhance endurance performance. The aims of this review are to examine the evidence of LCHF diets in improving various aspects of athletic performance. Long-term LCHF dietary intake may help control body weight and fat mass while maintaining lean body mass in athletes in weight-sensitive sports. LCHF-adapted endurance athletes can reach the maximal fat oxidation rate of approximately 1...

Matthew J Jordan, Per Aagaard, Walter Herzog
The purpose of the present review was to: 1) provide an overview of the current understanding on the epidemiology, etiology, risk factors, and prevention methods for anterior cruciate ligament (ACL) injury in alpine ski racing; and 2) provide an overview of what is known pertaining to ACL reinjury and return to sport after ACL injury in alpine ski racing. Given that most of the scientific studies on ACL injuries in alpine ski racing have been descriptive, and that very few studies contributed higher level scientific evidence, a nonsystematic narrative review was employed...

REVIEW
Erika Zemková
Recently, resistance exercises performed on an unstable surface have become part of athletic training and rehabilitation. Accordingly, their role in performance and health-oriented strength training has increasingly emerged as a matter of interest to researchers and conditioning specialists. A more pronounced activation of stabilizing muscles is assumed to be the main feature of instability resistance exercises. This assumption has been proven by EMG studies, which have highlighted significantly greater electromyographic activity of trunk-stabilizing muscles during exercises under unstable as compared to stable conditions...

OBJECTIVES: To retrospectively compare the longitudinal physical development of junior rugby league players between the Under 13 and 15 age categories in relation to their adult career attainment outcome. DESIGN: Retrospective longitudinal design. METHODS: Fifty-one former junior rugby league players were retrospectively grouped according to their career attainment outcome as adults (i.e., amateur, academy or professional). As juniors, players undertook a physical testing battery on three consecutive annual occasions (Under 13s, 14s, 15s) including height, body mass, sum of four skinfolds, maturation, vertical jump, medicine ball chest throw, 10-60m sprint, agility 505 and estimated V˙O2max ...

Selection biases based on the use of cut-off dates and the timing of athletes' birthdates have been termed relative age effects. These effects have been shown to differentially affect individuals involved in sport. For example, young male soccer players born early in their age group are overrepresented in elite teams while studies in adult soccer indicated potential carry-over effects from talent development systems. This two-study approach focuses on the processes within multi-year age groups in youth and adult elite soccer and on the role of players' age position within the age band with regard to players' birth year and birth month...

BACKGROUND: Within athletics and the military, ankle sprains are one of the most common injuries with the potential for long-term functional deficits. Incidence rates for ankle sprains within the military are one of the leading causes of limited duty days, especially during basic combat training, parachute training exercises, and in cadet populations. In 2008, the Department of Defense U.S. Army Center for Health Promotion and Preventative Medicine report recommended that military personnel should wear semirigid ankle braces during parachuting, basketball, soccer, and other similar high-risk activities to reduce ankle sprain injuries...

Assessment, treatment, and management of sport-related concussions are a widely recognized public health issue. Although several neuropsychological and motor assessment tools have been developed and implemented for sports teams at various levels and ages, the sensitivity of these tests has yet to be validated with more objective measures to make return-to-play (RTP) decisions more confidently. The present study sought to analyze the residual effect of concussions on a sample of adolescent athletes who sustained one or more previous concussions compared to those who had no concussion history...

Compared with mainstream sport athletes, relatively little is known regarding the factors affecting the development of athletes with a disability. Sport-specific training programs are essential to athletes' successful performance; to create appropriate programs and strategies, a clear understanding of the nuances of development of athletes with a disability is important. The objective of this systematic review was to synthesize existing research on development in athletes with a disability and examine the key determinants of successful development and sporting performance...

OBJECTIVE: Chefs exert expert motor and cognitive performances on a daily basis. Neuroimaging has clearly shown that that long-term skill learning (i.e., athletes, musicians, chess player or sommeliers) induces plastic changes in the brain thus enabling tasks to be performed faster and more accurately. How a chef's expertise is embodied in a specific neural network has never been investigated. METHODS: Eleven Italian head chefs with long-term brigade management expertise and 11 demographically-/ psychologically- matched non-experts underwent morphological evaluations...

BACKGROUND: The anatomy of hip is widely complex and several anatomical structures interact and contribute to its functioning. For position and role, hip and the surrounding tendons, which have their insertion around, are overstressed and often overloaded, especially in athletes. This could lead to the developing of several tendinopathies, among which the differential diagnosis is often complicated. Many conservative treatments are used in clinical practice, while actually, no defined conservative protocol is recommended...

Patellofemoral pain (PFP) has historically been a complex and enigmatic issue. Many of the factors thought to relate to PFP remain after patients' symptoms have resolved making their clinical importance difficult to determine. The tissue homeostasis model proposed by Dye in 2005 can assist with understanding and implementing biomechanical interventions for PFP. Under this model, the goal of interventions for PFP should be to re-establish patellofemoral joint (PFJ) homeostasis through a temporary alteration of load to the offended tissue, followed by incrementally restoring the envelope of function to the baseline level or higher...
