The effects of exercise on sleep have been explored from various perspectives, but little is known about how the effects of acute exercise on sleep are produced through physiological functions.We used a protocol of multiple daytime sessions of moderate-intensity aerobic exerciseand examined the subsequenteffects on sleep structure, core body temperature, distal-proximal skin temperature gradient, and subjective parameters. Fourteen healthy men who did not exercise regularly were evaluated under the baseline (no exercise) and exercise conditions on a within-subject crossover basis. Under the exercise condition, each participant performed a 40-min aerobic workout at 40% of maximal oxygen intakefour times between morning and early evening. We observed a 33% increase in slow-wave sleep (=0.005), as well as increases in slow-wave activity (=0.026), the fast-sigma power/slow-wave activity ratio (=0.005), and subjective sleep depth and restorativeness the following morning. Moreover, both core body temperature and the distal-proximal skin temperature gradient increased during sleep after exercise (=0.021 and =0.047, respectively). Regression analysis identified increased nocturnal distal-proximal skin temperature gradient during sleep after exercise as a factor in the increase in slow-wave activity. The fast-sigma/ slow-wave activity ratio correlated with core body temperature. Performing acute exercise promotes slow-wave sleep with nocturnal elevation in the distal-proximal skin temperature gradient. Both core body temperature and fast-sigma power may play a role in the specific physiological status of the body after exercise.

The macro- and microstructural characteristics of sleep electroencephalography have been associated with several aspects of executive functioning. However, only a few studies have addressed the associ...
T-wave alternans (TWA) is a risk stratification predictor for sudden cardiac death. However, little is known about the diurnal variation of TWA. Whether TWA are affected by heart rate (HR) or cardiac ...
Increasing exercise reinforcement, or decreasing sedentary reinforcement, may reduce sedentary activity and promote habitual exercise. Repeated exposures to a reinforcer may increase its reinforcing v...
The purpose was to determine if the Alu-insertion (I)/deletion (D) polymorphism of the tissue plasminogen activator (tPA) gene influences the tPA response to maximal exercise. Fifty male subjects (age...

This is an observational study to determine if the presentation of sensory stimulation during sleep can increase slow-wave activity during non-rapid eye movement sleep
A single bout of Interval-Walking (IW) exercise is superior to energy-expenditure and time-duration matched Continuous Walking (CW) exercise upon improving glycemic control. The time spend...
In clinical practice at the National centre for epilepsy (SSE) in Norway we see many children who have subclinical epileptiform activity in EEG that increases substantially during slow wav...
Hypothesis: during fasting and exercise will there be an activation of sirtuins (Sirt1). Primarily the investigators will investigate Sirt1 activity in muscle- and fat-biopsies after fast...
This project aims at gaining insight into the role of sleep in motor learning and the first to apply sleep related learning methods in a rehabilitative setting. The primary objective is to...
Abnormally rapid heartbeats caused by reentry of atrial impulse into the dual (fast and slow) pathways of ATRIOVENTRICULAR NODE. The common type involves a blocked atrial impulse in the slow pathway which reenters the fast pathway in a retrograde direction and simultaneously conducts to the atria and the ventricles leading to rapid HEART RATE of 150-250 beats per minute.
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
Tapering-off physical activity from vigorous to light, to gradually return the body to pre-exercise condition and metabolic state.
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
One of the MARTIAL ARTS and also a form of meditative exercise using methodically slow circular stretching movements and positions of body balance.
Sleep disorders disrupt sleep during the night, or cause sleepiness during the day, caused by physiological or psychological factors. The common ones include snoring and sleep apnea, insomnia, parasomnias, sleep paralysis, restless legs syndrome, circa...
