Youth sports participation numbers continue to grow in the United States. A shift toward sport specialization has caused an increase in sport training frequency and intensity that places the growing athlete at risk for overtraining, nutritional deficits, and injuries. Individuals who participate in endurance sports are at especially high risk. Youth runners and swimmers are high-risk populations that require special attention to their training schedules, nutritional intake, and injuries. Appropriate scheduling of training, dedicating time to rest, and nutrition education can help prevent problems in the endurance athlete...

Sports-related concussion (SRC) is a common problem in youth sports. Concussion may occur after a forceful hit to the body or head, resulting in transient neuropathological changes that spontaneously resolve with relative rest and activity modification in most patients. Most SRCs are effectively managed by primary care physicians and sports medicine specialists. In some cases, symptoms may persist and the child and adolescent psychiatrist may be consulted. This article reviews important background information regarding SRC and highlights a variety of pharmacologic and nonpharmacologic treatment options that consultant psychiatrists should know...

In resistance training, load intensity is usually calculated as the percentage of a maximum repetition (1RM) or maximum number of possible repetitions (% of 1RM). Some studies have proposed a lactate threshold (LT) intensity as an optimal approach for concurrent training of cardiorespiratory endurance and muscle strength, as well as an alternative in resistance training. The objective of the present study was to analyze the results obtained in research evaluating the use of LT in resistance training. A keyword and search tree strategy identified 14 relevant articles in the Dialnet, Elsevier, Medline, Pubmed, Scopus and Web of Science databases...

Felix Tsui, Matthew T G Pain
Despite uncertainty of its exact role, muscle tension has shown an ability to alter human biomechanical response and may have the ability to reduce impact injury severity. The aim of this study was to examine the effects of muscle tension on human impact response in terms of force and energy absorbed and the subjects' perceptions of pain. Seven male martial artists had a 3.9 kg medicine ball dropped vertically from seven different heights, 1.0-1.6 m in equal increments, onto their right thigh. Subjects were instructed to either relax or tense the quadriceps via knee extension (≥60% MVC) prior to each impact...

John Kiely
Periodization theory has, over the past seven decades, emerged as the preeminent training planning paradigm. The philosophical underpinnings of periodization theory can be traced back to the integration of diverse shaping influences, whereby coaching beliefs and traditions were blended with historically available scientific insights and contextualized against pervading social planning models. Since then, many dimensions of elite preparation have evolved significantly, as driven by a combination of coaching innovations and science-led advances in training theory, techniques, and technologies...

CONTEXT:   Dynamic balance during functional movement may provide important clinical information after concussion. The Sport Concussion Assessment Tool version 3 (SCAT3) includes a timed tandem-gait test (heel-to-toe walking) administered with a pass-fail scoring system. Minimal evidence supports inclusion of the tandem-gait test in the SCAT3, especially in high school athletes. OBJECTIVE:   To determine (1) the percentage of healthy high school athletes who passed (best trial ≤14 seconds) the tandem-gait test at baseline, (2) the association between sex and test performance (pass versus fail), and (3) the relationship among sex, age, height, and tandem-gait test score...

REVIEW
Travis Anderson, Laurie Wideman
BACKGROUND: The cortisol awakening response (CAR) has been used as a biomarker of stress response in a multitude of psychological investigations. While a myriad of biochemical responses have been proposed to monitor responses to exercise training, the use of CAR within the exercise and sports sciences is currently limited and is a potentially underutilized variable. Therefore, the purpose of this review was to collate studies that incorporate both exercise and CAR, in an effort to better understand (a) whether CAR is a useful marker for monitoring exercise stress and (b) how CAR may be most appropriately used in future research...

Resistance training is the most effective method to increase muscle mass. It has also been shown to promote many health benefits. Although it is deemed safe and of clinical relevance for treating and preventing a vast number of diseases, a time-efficient and minimal dose of exercise has been the focus of a great number of research studies. Similarly, an inverted U-shaped relationship between training dose/volume and physiological response has been hypothesized to exist. However, the majority of available evidence supports a clear dose-response relationship between resistance training volume and physiological responses, such as muscle hypertrophy and health outcomes...
