Overtraining syndrome (OTS) is caused by an imbalance between training, nutrition and resting, and leads to decreased performance and fatigue; however, the precise underlying triggers of OTS remain unclear. This study investigated the body composition, metabolism, eating, sleeping patterns and mood states among participants with OTS. Selected participants were divided into OTS-affected athletes (OTS, n = 14), healthy athletes (ATL, n = 25), and healthy non-physically active controls (NCS, n = 12). Compared to ATL, OTS showed decreased sleep quality (p = 0...

Karsten Koehler, Clemens Drenowatz
In order to monitor their energy requirements, athletes may desire to assess energy expenditure (EE) during training and competition. Recent technological advances and increased customer interest have created a market for wearable devices that measure physiological variables and bodily movement over prolonged time periods and convert this information into EE data. This mini-review provides an overview of the applicability of the SenseWear armband (SWA), which combines accelerometry with measurements of heat production and skin conductivity, to measure total daily energy expenditure (TDEE) and its components such as exercise energy expenditure (ExEE) in athletic populations...

OBJECTIVES: Persistent poor sleep is associated with a range of adverse health outcomes. Sleep is considered the main method of recovery in athletes; however, studies report that a significant number of athletes are getting insufficient sleep. The purpose of this study was to assess the sleep profiles of elite Gaelic athletes and to compare wellbeing in those with poor sleep and those with good sleep. METHODS: 69 elite Gaelic athletes completed questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), Subjective Health Complaints Inventory (SHC), Nordic Musculoskeletal Questionnaire (NMQ), stress subscale of the Depression Anxiety Stress Scale (DASS), the tension-anxiety, anger-hostility and confusion-bewilderment subscales of the Profile of Mood States (POMS) as well as the catastrophising subscale of the Coping Strategies Questionnaire (CSQ)...

REVIEW
Danit Atias-Varon, Yuval Heled
Prolonged and strenuous exercise may lead to changes in the immune system function and to temporary suppression in defense against pathogens. These changes likely increase the risk of those engaging in prolonged and strenuous physical activity to develop upper respiratory tract infection and to reduce the level of performance. On the other hand, it appears that moderate physical activity reduces the risk of upper respiratory tract infection. Various populations, such as professional athletes and soldiers in combat units, who engage in daily strenuous exercise, may therefore be a high risk group...

Despite growing evidence of the positive impact of later school start times on adolescent health and academic outcomes, relatively few districts have changed start times due to concerns about transportation, child care, and athletics/extracurricular activities. This paper provides a case study of the Cherry Creek School District's (CCSD) successful efforts to change start times. The CCSD is a diverse district with an enrollment of almost 55,000 students in suburban Denver. As part of CCSD's strategic plan, a multi-disciplinary task force was formed to examine the impact of start times on student achievement, and recommend a start time schedule driven by best practices on adolescent sleep patterns, balanced with family and community needs...

Sleep is an essential component of health and well-being, with significant impacts on physical development, emotional regulation, cognitive performance, and quality of life. Along with being an integral part of the recovery and adaptive process between bouts of exercise, accumulating evidence suggests that increased sleep duration and improved sleep quality in athletes are associated with improved performance and competitive success. In addition, better sleep may reduce the risk of both injury and illness in athletes, not only optimizing health but also potentially enhancing performance through increased participation in training...

CONTEXT:   Capturing baseline data before a concussion can be a valuable tool in individualized care. However, not all athletes, including dancers, have access to baseline testing. When baseline examinations were not performed, clinicians consult normative values. Dancers are unique athletes; therefore, describing values specific to dancers may assist those working with these athletes in making more informed decisions. OBJECTIVE:   To describe values for key concussion measures of dancers...
