Effects of Physical Exercise on Individual Resting State EEG Alpha Peak Frequency

Previous research has shown that both acute and chronic physical exercises can induce positive effects on brain function and this is associated with improvements in cognitive performance. However, the neurophysiological mechanisms underlying the beneficial effects of exercise on cognitive processing are not well understood. This study examined the effects of an acute bout of physical exercise as well as four weeks of exercise training on the individual resting state electroencephalographic (EEG) alpha peak frequency (iAPF), a neurophysiological marker of the individual’s state of arousal and attention, in healthy young adults. The subjects completed a steady state exercise (SSE) protocol or an exhaustive exercise (EE) protocol, respectively, on two separate days. EEG activity was recorded for 2 min before exercise, immediately after exercise, and after 10 min of rest. All assessments were repeated following four weeks of exercise training to investigate whether an improvement in physical fitness modulates the resting state iAPF and/or the iAPF response to an acute bout of SSE and EE. The iAPF was significantly increased following EE (P=0.012) but not following SSE. It is concluded that the iAPF is increased following intense exercise, indicating a higher level of arousal and preparedness for external input.

Alpha Peak

The Free and Cued Selective Reminding Test (FCSRT) is a largely validated neuropsychological test for the identification of amnestic syndrome from the early stage of Alzheimers disease (AD). Previous electrophysiological data suggested a slowing down of the alpha rhythm in the AD-continuum as well as a key role of this rhythmic brain activity for episodic memory processes. This study therefore investigates the link between alpha brain activity and alterations in episodic memory as assessed by the FCSRT. For that purpose, 37 patients with altered FCSRT performance underwent a comprehensive neuropsychological assessment, supplemented by 18F-fluorodeoxyglucose positron emission tomography/structural magnetic resonance imaging (18FDG-PET/MR), and 10 minutes of resting-state magnetoencephalography (MEG). The individual alpha peak frequency (APF) in MEG resting-state data was positively correlated with patients encoding efficiency as well as with the efficacy of semantic cues in facilitating patients retrieval of previous stored word. The APF also correlated positively with patients hippocampal volume and their regional glucose consumption in the posterior cingulate cortex. Overall, this study demonstrates that alterations in the ability to learn and store new information for a relatively short-term period are related to a slowing down of alpha rhythmic activity, possibly due to altered interactions in the extended mnemonic system. As such, a decreased APF may be considered as an electrophysiological correlate of short-term episodic memory dysfunction accompanying pathological aging.

The use of biofeedback (BFB) technology becomes relevant for professional training of musicians to achieve success in psychomotor function control. We compared two training approaches: 20-22 sessions of alpha-EEG/EMG biofeedback implication to increase the аlpha-2 power while reducing the tension of the forehead muscles and sham biofeedback training. Fifty student musicians (18-28 years old) were divided randomly by age, gender, performing specialty, and individual EEG alpha-peak frequency (IAPF) into two groups. Music performance, state anxiety, self-actualization, nonverbal creativity, coeﬃcient of ﬁnger movement optimality (Ko) and the eﬃciency of the single training session (E1) were evaluated before and after for both types of courses. We calculated the change of the EEG power in the individually adjusted alpha-2 range in the Pz and the integrated EMG power of the surface muscles of the forehead in response to ﬁnger movement. Training with biofeedback improved music performance score, increased self-actualization, Ko, and E1 while reducing pre-stage anxiety. The students who received the sham biofeedback did not achieve such improvements. When using biofeedback, students with baseline low alpha-peak frequency (LF) showed a more signiﬁcant increase in scores for music performance, Ko, and E1 than students with high alpha-peak frequency (HF). In LF students, the sessions without biofeedback did not change the studied parameters. In this pilot placebo-controlled study, we demonstrated that achieving success in the optimal musical performance training depends on the baseline genetically determined IAPF and feedback implication from the EEG alpha-2 power and forehead muscle tone.
