Sensorimotor rhythm (SMR) activity has been related to automaticity during skilled action execution. However, few studies have bridged the causal link between SMR activity and sports performance. This study investigated the effect of SMR neurofeedback training (SMR NFT) on golf putting performance. We hypothesized that pre-elite golfers would exhib...
Psychomotor efficiency has been linked with processing efficiency during sport performance. Reduced cortical activity in the sensorimotor area has been related to less variability in the movement preparation that is conducive to skilled motor performance. This study proposes sensorimotor rhythm (SMR), 12–15 Hz of the electroencephalogram (EEG) in t...
Previous evidence suggests that augmented sensorimotor rhythm (SMR) activity is related to the superior regulation of processing cognitive-motor information in motor performance. However, no published studies have examined the relationship between SMR and performance in precision sports; thus, this study examined the relationship between SMR activi...
Neurofeedback training (NFT) is a technique in which we train the brain to help improve its functioning through self-regulation of the electroencephalogram (EEG).

Introduction
Achieving optimal visuomotor performance in precision sports relies on maintaining an optimal psychological state during motor preparation. To uncover the optimal psychological state, extensive EEG studies have established a link between the Mu rhythm (8–13 Hz at Cz) and cognitive resource allocation during visuomotor tasks (i.e., golf...
This study examined the effects of different fatigue types on action anticipation and physical performance in high-level volleyball players. Twenty-four participants underwent four counterbalanced conditions: 60-min of cycling at 60% peak power output, 60-min Stroop task, 60-min cycling at 60% peak power output with Stroop task and 60-min neutral d...
The impact of sleep deprivation on working memory can only be reversed by recovery sleep (RS). However, there are limited electrophysiological studies on the effect of RS on the improvement in working memory after sleep deprivation, and the changes in the early components of event-related potentials (ERPs) before and after RS are still unclear. The...
A major concern voiced by motor behavior scientists is to find useful practice techniques that can be effective in improving motor learning and performance. Neurofeedback and self-controlled practice are among the techniques that have recently drawn attention from specialists in this area. The present study examined the additive and individual effe...
For elite performers, psychomotor behavior's success or failure can be traced to differences in brain dynamics. The psychomotor efficiency hypothesis suggests refined cortical activity through 1) selective activation of task-relevant processes and 2) inhibition of non-essential processes. The use of electroencephalography (EEG) has been applied to...
This study characterized the adaptive attentional allocation that occurs during motor preparation. The specifications of task-relevant and task-irrelevant neural processes are key processes that facilitate successful performances by skilled athletes under difficult task conditions. Previous sport psychophysiology studies have used event-related des...
Transcranial direct current stimulation (tDCS) is a promising tool to enhance cognitive performance. However, its effectiveness has not yet been unequivocally shown. Thus, here we tested whether coupling tDCS with a bout of aerobic exercise (AE) is more effective in modulating cognitive functions than tDCS or AE alone. One hundred twenty-two health...
The meshed control theory assumes that cognitive control and automatic processes work together in the natural attention of experts for superior performance. However, the methods adopted by previous studies limit their capacity to provide in-depth information on the neuromotor processes. This experiment tested the theory with an alternative approach...
When it is applied in sports, biofeedback training (BFT) is a technique that can enable athletes to modify their psychophysiological behavior by regulating their biological signals (referred to as modalities) in response to real-time feedback, which may result in desirable psychological processes and/or behavioral outcomes, such as improved accurac...
There is converging evidence that both aerobic exercise (AE) and transcranial direct current stimulation (tDCS) can acutely modulate executive functions (EF). In addition, recent studies have proposed the beneficial effects of applying tDCS during AE on physical performance. This study aimed to investigate whether tDCS applied during an AE session...
The present study extends the sport neuroscience literature by comparing elite and amateur golfers during golf putting and examining the essential cognitive-motor processes that may contribute to understanding the superior cognitive-
motor performance of skilled performers. Twenty elite and 18 amateur golfers were recruited to perform 60 putts whil...
The brain is the main locus of control for our behaviour and psychological states. Superior sport performance occurs when both the physical and mental dimension of an athlete converge in an adaptive manner to meet the challenges of the task. This chapter provides an overview of how the brain works for athletes at different levels of expertise and d...
EEG neurofeedback training (EEG NFT) is a technique to help the athletes modulate their brain waves by providing the real-time feedback signals captured by the athletes themselves. The aim of using EEG NFT is to facilitate the athletes to achieve the adaptive psychological states and, thus, leading to superior sports performance (Gruzelier, 2014)....
Background
The efficacy of emotional and motivational regulation can determine athletic performance. Giving the short duration and fast changing nature of emotions experienced by athletes in competition, it is important to examine the temporal dynamics of emotional and motivational regulation. The aim of this study was to investigate emotional and...

The brain and the behavior are interconnected. To study the superior performance, a fundamental approach is to get the insight into what happens in the brain during the performance. In this dissertation, the focus is to investigate the missing link between the psychomotor efficiency hypothesis and the electroencephalography (EEG) activity.
Psychom...
Objective: Psychomotor efficiency refers to the processing efficiency in the cortical activity in sports performance. Superior performers achieve the high psychomotor efficiency by attenuating the irrelevant cortical processing. Encouraging reports from previous studies pointed out a close relationship between the cortical activity in the sensorimo...

Mu rhythm is most pronounced at the sensorimotor area of the brain within the frequency band between 8-13 Hz. The decrease of mu rhythm has been related to better motor preparation. Although previous studies have demonstrated lower mu rhythm in skilled golfers than that of the novices in simple motor skills, whether a similar pattern of differences...

Purpose: The purpose of current study was to examine whether SMR (Sensorimotor rhythm) neurofeedback training (NFT) have a positive effect on golf putting, cortical activity before putting, and self-reported mental state. SMR is so called 12-15Hz on sensorimotor cortex. Previous studies revealed that higher SMR power was related to optimal motor re...
Sensory motor rhythm (SMR) (12-15 Hz) originates in ventrobasal nuclei, and is related to the inhibition of afferent thalamic somatosensory information. According to recent findings of neurophysiological studies, SMR has a negative correlation to activity in the sensory motor area. Furthermore, SMR is associated with reduced external information in...
Compared to previous studies which have examined the relationship between EEG frequency and reaction time prior to the onset of imperative signals, this study attempted to further examine EEG activity before a warning signal.
