Beta and alpha electroencephalographic activity changes after acute exercise

Abstract: -Exercise has been widely related to changes in cortical activation and enhanced brain functioning. Quantitative electroencephalography (qEEG) is frequently used to investigate normal and pathological conditions in the brain cortex. Therefore, the aim of the present study was to observe absolute power alterations in beta and alpha frequency bands after a maximal effort exercise. Ten healthy young volunteers were submitted to an eight-minute resting EEG (eyes closed) followed by a maximal exercise test using a … Show more

“…In line with this assumption, acute exercise manipulations have been shown to affect oscillatory activity in the human EEG (Bailey et al 2008;Moraes et al 2007). For example, studies have reported that exercise increases oscillatory activity in the alpha range during subsequent cognitive performance, often localized to the right frontal hemisphere (Petruzzello and landers 1994).…”

“…Globally, stimulation of the midbrain reticular formation and other wake-active areas induces electroencephalogram activation and arousal (i.e., reduced theta activity, increased beta activity), whereas stimulation of the solitary tract nucleus, the ventrolateral preoptic area, and the median preoptic nucleus often induces electroencephalogram slowing and sleep (i.e., increased theta activity, reduced beta activity) [27,64,65]. When awake with eyes closed, the brainwave patterns of most individuals show unambiguous occipital alpha rhythm; the moment of sleep onset is associated with the abrupt disappearance of this alpha rhythm [33].…”

“…It has been shown that cold water immersion (15 min at 15°C) significantly increases electrocortical beta3 activity [64]. Since electrocortical reduced theta activity and increased beta activity characterize electroencephalogram activation and arousal [27,64,65], a cold water immersion-induced electrocortical state may not favor sleep induction. Additionally, Harris [121] has previously described the physiological changes during the transition from wakefulness to sleep, which includes a decrease in sympathetic activity and an increase in parasympathetic activity.…”

“…The electroencefalogram (EEG) is a common and aVordable technique in clinical and sports research. To understand the eVects of exercise on the brain, several studies have investigated EEG activity either after or during exercise (Kubitz and Mott 1996;Kubitz and Pothakos 1997;Mechau et al 1998;Oda et al 1999;Woo et al 2009;Schneider et al 2009a; Moraes et al 2007). EEG activities originate in cortical generators and are modulated via neurotransmitters (Olejniczak 2006).…”
