Collegiate student athletes face psychological stressors in adjusting to campus life. This study used preexisting, nationally representative data administered by the National Collegiate Athletic Association for student athletes in 2010 to explore the conjunctive relationships among demographics, personal characteristics, social contexts, and physical condition in predicting perceived stress. The number of valid samples was 19,967 from 609 member institutions. A data mining methodology (i.e., SEARCH) was applied to model the distribution of the perceived stress...

BACKGROUND/AIM: There is increasing popularity for athletes to use heart rate variability (HRV) to tailor training. A time-efficient method is HRV assessment during deep sleep. The aim was to validate the selection of deep sleep segments identified by RR-intervals with simultaneous electroencephalography (EEG) recordings and to compare HRV parameters of these segments with those of standard morning supine measurements. METHODS: In 11 world class alpine- skiers, RR-intervals were monitored during ten nights and simultaneous EEGs were recorded in 2-4 nights...

The aim of this pilot study was to investigate the effects of an intervention consisting of mental coaching combined with either electro encephalogram (EEG) alpha power feedback or heart rate variability (HRV) feedback on HRV, EEG outcomes and self-reported factors related to stress, performance, recovery and sleep quality in elite athletes. A prospective pilot study was performed with two distinct cohorts. Soccer players were provided with four sessions of mental coaching combined with daily HRV biofeedback (Group A); track and field athletes were provided with four sessions of mental coaching in combination with daily neurofeedback (Group B)...

Athletes and coaches at all competitive levels will utilize sports performance and psychiatric services at very high rates if the services are offered on-site and free of charge and are broad in scope and culturally sensitive. Services should be available throughout the team year and cover areas such as team building, mental preparation, stress control, substance prevention, sleep and energy regulation, injury recovery, crisis intervention, and mental disorder treatment. The staff offering these services should be diverse by gender, profession, and culture, and the fees should be paid by the organization...

OBJECTIVES: Muslims observe fasting during the month of Ramadan by abstaining from eating and drinking from dawn to sunset. Available literature shows that although several studies have been conducted on athletes to determine the effects of Ramadan fasting in terms of physical fitness and performance, little data are available regarding the knowledge, beliefs and attitudes of athletes (particularly footballers) towards Ramadan fasting during high-level competitions. This study explored the knowledge, beliefs and attitudes towards Ramadan fasting among football players participating in the London 2012 Olympics football tournament...

Traumatic brain injury is an increasingly common public health issue, with the mild variant most clinically relevant for this chapter. Common causes of mild traumatic brain injury (mTBI) include motor vehicle accidents, athletics, and military training/deployment. Despite a range of clinically available testing platforms, diagnosis of mTBI remains challenging. Symptoms are primarily neurosensory, and include dizziness, hearing problems, headaches, cognitive, and sleep disturbances. Dizziness is nearly universally present in all mTBI patients, and is the easiest symptom to objectify for diagnosis...

BACKGROUND: The concept of mental toughness (MT) has gained increasing importance among groups other than elite athletes by virtue of its psychological importance and explanatory power for a broad range of health-related behaviors. However, no study has focused so far on the psychological origins of MT. Therefore, the aims of the present study were: to explore, to what extent the psychological profiles of preschoolers aged five were associated with both (1) MT scores and (2) sleep disturbances at age 14, and 3) to explore possible gender differences...

Chronic traumatic encephalopathy (CTE) is a neuropathologically defined disease reportedly linked to a history of repetitive brain trauma. As such, retired collision sport athletes are likely at heightened risk for developing CTE. Researchers have described distinct pathological features of CTE as well a wide range of clinical symptom presentations, recently termed traumatic encephalopathy syndrome (TES). These clinical symptoms are highly variable, non-specific to individuals described as having CTE pathology in case reports, and are often associated with many other factors...

Little is known about health variables and if these variables could increase the risk of injuries among adolescent elite athletes. The primary aim was to present overall data on self-perceived stress, nutrition intake, self-esteem, and sleep, as well as gender and age differences, on two occasions among adolescent elite athletes. A secondary aim was to study these health variables as potential risk factors on injury incidence. A questionnaire was e-mailed to 340 adolescent elite athletes on two occasions during a single school year: autumn semester and spring semester...

The postpartum period in a woman's life is filled with numerous changes, including physical changes, changes in sleep habits, and learning how to best care for a newborn. A common goal among postpartum women is to either begin or resume an active lifestyle, which often includes physical activity such as running, biking and swimming. The postpartum athlete may discover barriers that prevent her from returning to or beginning an exercise routine. These obstacles include muscle weakness, fatigue, depression and physical changes that require exercise modification...

There is an ongoing discussion in the media about the Zika virus and the question of whether or not athletes and visitors will be at risk of an infection during the Olympic Games in Rio de Janeiro in 2016. According to an assessment published on 31 May 2016 by the IOC and the WHO, participants and visitors have no reason to panic. However, increasing public pressure has caused the WHO to re-evaluate the current situation, and further recommendations will likely be given before the Olympic Games start. The current facts are as follows: 1) The Olympic Summer Games will be held during the winter months in Brazil, when the appearance of mosquitoes is expected to be low...
