OBJECTIVES Sleep is essential for recovery and performance in elite athletes. While it is generally assumed that exercise benefits sleep, high training load may jeopardize sleep and hence limit adequate recovery. To examine this, the current study assessed objective sleep quantity and sleep stage distributions in elite athletes and calculated their association with perceived training load. DE...

BACKGROUND Patients undergoing renal transplantation consume immunosuppressive drugs to prevent graft rejection. Cardiovascular complications and reduced quality of sleep are among the side effects of these drugs. Studies have indicated that the use of non-therapeutic methods such as exercise is important to reduce these complications. OBJECTIVE To evaluate the effect of a period of exercise ...

A good quality and quantity of night sleep is a substantial factor in allowing the adequate daytime functioning of human beings. Life styles of industrialized countries have been changed from last decades, and sleep-wake patterns have been adapted to new needs and society demands. Sleep duration has decreased, daytime sleepiness has increased and complaints about the poor quality of sleep are f...

Despite a growing body of literature demonstrating a positive relationship between sleep and optimal performance, athletes often have low sleep quality and quantity. Insufficient sleep among athletes may be due to scheduling constraints and the low priority of sleep relative to other training demands, as well as a lack of awareness of the role of sleep in optimizing athletic performance. Domain...

PURPOSE The present study explored the effect of various lifestyle patterns and sleep-related factors on the sleep-related road risk. Sleep-related factors included daytime sleepiness, drowsy driving and quality/quantify of sleep. METHODS A sample of 1366 non-professional drivers aged 19-65 was selected from the broader Athens area of Greece, using stratified random sampling. The questionnair...

Due to the high demands of competitive sports, sleep architecture adolescent athletes may be influenced by their regular training. To date, there is no clear evidence on how training characteristics (intensity, time day, number sessions) influence quality and quantity. 53 male soccer players (M = 14.36 years, SD 0.55) Austrian U15 (n 45) U16 elite teams 8) were tested at least three consecutive...

Older adults do not sleep as well as younger adults. Why? What alterations in sleep quantity and quality occur as we age, and are there functional consequences? What are the underlying neural mechanisms that explain age-related sleep disruption? This review tackles these questions. First, we describe canonical changes in human sleep quantity and quality in cognitively normal older adults. Secon...

OBJECTIVES This study tested the directionality of the association between sleep and health outcomes in youth with asthma. METHOD Thirty-eight youth with asthma (aged 9-19) completed a daily diary study on sleep, asthma symptoms, peak expiratory flow (PEF) measures, and salivary cortisol samples. RESULTS Greater quantity of sleep predicted lower PEF% [beta(32) = -.33, p =.02], and lower dai...
