“…This difference between groups should also be detectable as prolonged, extended-focus activations in the sustained-attention-related brain regions (i.e., anterior cingulate, prefrontal and parietal areas). We propose that skilled athletes will show better attentional abilities, which will be reflected as better performance in the sustained-attention task, and that this performance can be related to differences in the various components of the ERP (particularly larger amplitudes in the components related to attention: P100, P200 and P300), consistent with previous reports ( Hack, Memmert & Rupp, 2009 ; Hamon & Seri, 1989 ; Hung et al, 2004 ; Jin et al, 2011 ; Ozmerdivenli et al, 2005 ; Zwierko et al, 2011 ). Moreover, these behavioral and ERP features will likely correlate with greater activation, in skilled athletes, in the brain structures implicated in sustained attention (anterior cingulate, dorsolateral prefrontal, and parietal cortical regions primarily in the right hemisphere) as previous neuropsychological studies report ( Cohen et al, 1992 ; Fink et al, 1997 ; Pardo, Fox & Raichle, 1991 ).…”

“…The posterior P200 response to an action-anticipation task was different between professional badminton players and non-players, with professionals showing larger amplitudes than non-players; the authors proposed that the players showed superior action-anticipation abilities associated with an enhanced P200 effect that had a posterior-occipital distribution ( Jin et al, 2011 ). Additionally, larger amplitudes in the P200 component have been found in sprinters compared with other populations; the authors proposed that smaller amplitudes in the control groups could indicate lower attention levels ( Hamon & Seri, 1989 ). Based on these studies and on the hypothesis that the P200 component could be an index of a stimulus-identification process and establishing a perceptual decision ( Lindholm & Koriath, 1985 ), this effect in our results likely reflects some generic training effects.…”

“…The role of expertise and training in attention and brain activity has been investigated using the ERP technique and sLORETA. In previous studies ( Babiloni et al, 2010a ; Del Percio et al, 2010 ; Fontani & Lodi, 2002 ; Fontani et al, 2006 ; Fontani et al, 1999 ; Hack, Memmert & Rupp, 2009 ; Hamon & Seri, 1989 ; Hung et al, 2004 ; Radlo et al, 2001 ), behavioral performance, electrophysiological brain activity, and current sources were shown to have distinct characteristics when compared between experts and non-experts or non-athletes, which suggests that people with training in different skills and sports may have attentional profiles related to their expertise. Specifically, ERP studies have found larger amplitudes in components associated with attention (e.g., P100, P200, and P300) in expert athletes than in other populations ( Hack, Memmert & Rupp, 2009 ; Hamon & Seri, 1989 ; Hung et al, 2004 ; Jin et al, 2011 ; Ozmerdivenli et al, 2005 ; Zwierko et al, 2011 ); the authors interpreted these higher amplitudes as indicators of better attentional mechanisms in experts.…”

Background. Research on sports has revealed that behavioral responses and event-related brain potentials (ERP) are better in expert than in novice athletes for sport-related tasks. Focused attention is essential for optimal athletic performance across different sports but mainly in combat disciplines. During combat, long periods of focused attention (i.e., sustained attention) are required for a good performance. Few investigations have reported effects of expertise on brain electrical activity and its neural generators during sport-unrelated attention tasks. The aim of the present study was to assess the effect of expertise (i.e., skilled and novice martial arts athletes) analyzing the ERP during a sustained attention task (Continuous Performance Task; CPT) and the cortical three-dimensional distribution of current density, using the sLORETA technique. Methods. CPT consisted in an oddball-type paradigm presentation of five stimuli (different pointing arrows) where only one of them (an arrow pointing up right) required a motor response (i.e., target). CPT was administered to skilled and novice martial arts athletes while EEG were recorded. Amplitude ERP data from target and non-target stimuli were compared between groups. Subsequently, current source analysis for each ERP component was performed on each subject. sLORETA images were compared by condition and group using Statistical Non-Parametric Mapping analysis. Results. Skilled athletes showed significant amplitude differences between target and non-target conditions in early ERP components (P100 and P200) as opposed to the novice group; however, skilled athletes showed no significant effect of condition in N200 but novices did show a significant effect. Current source analysis showed greater differences in activations in skilled compared with novice athletes between conditions in the frontal (mainly in the Superior Frontal Gyrus and Medial Frontal Gyrus) and limbic (mainly in the Anterior Cingulate Gyrus) lobes. Discussion. These results are supported by previous findings regarding activation of neural structures that underlie sustained attention. Our findings may indicate a better-controlled attention in skilled athletes, which suggests that expertise can improve effectiveness in allocation of attentional resources during the first stages of cognitive processing during combat.

“…Previous studies on attention in athletes have investigated how perceptual and cognitive processes are improved as a result of sports practice. Expert athletes have shown better performance than beginners on cognitive tests (Fontani & Lodi, 2002;Hack, Memmert, & Rupp, 2009;Hamon & Seri, 1989;Radlo, Janelle, Barba, & Frehlich, 2001;Taliep et al, 2008). However, differences in cognitive processes among athletes of different athletic disciplines have been studied less frequently.…”

Attention processes are essential in athletic performance. Competition in combat sports requires high levels of attention, concentration and self-control. The aim of this study was to determine the differences in attention test performance among three groups of athletes from different disciplines of martial arts (judo, taekwondo and kung-fu). Twenty athletes with at least one year of experience in their respective sport were included in the study. The Test of Variables of Attention (TOVA) was performed, and data for the standard and Z scores of the quarters, halves and totals of each variable were analysed. The kung-fu athletes showed better inhibition response than the judo and taekwondo athletes. Minor performance deterioration during the impulsivity test was identified in kung-fu athletes compared with taekwondo and judo athletes. Judo athletes showed higher variability in reaction times than kung-fu athletes. Our study suggests that kung-fu training improved attention skills more than the other two disciplines. This effect can be explained by the athletes' dedication to kung-fu training and the sport's promotion of discipline, self-control and meditation.

“…Most of the previous ERP studies on athletes have compared experts with beginners or non-athletes and have found differences between groups in the amplitude and latency of different ERP components. These differences have been associated with expertise, sports discipline and level of task demand [14], [15], [16], [17], [18], [19], [20], [21], [22]. Additionally, movement-related cortical potential (MRCP) has been studied in this population.…”

Differences in Visuo-Motor Control in Skilled vs. Novice Martial Arts Athletes during Sustained and Transient Attention Tasks: A Motor-Related Cortical Potential Study

Cognitive and motor processes are essential for optimal athletic performance. Individuals trained in different skills and sports may have specialized cognitive abilities and motor strategies related to the characteristics of the activity and the effects of training and expertise. Most studies have investigated differences in motor-related cortical potential (MRCP) during self-paced tasks in athletes but not in stimulus-related tasks. The aim of the present study was to identify the differences in performance and MRCP between skilled and novice martial arts athletes during two different types of tasks: a sustained attention task and a transient attention task. Behavioral and electrophysiological data from twenty-two martial arts athletes were obtained while they performed a continuous performance task (CPT) to measure sustained attention and a cued continuous performance task (c-CPT) to measure transient attention. MRCP components were analyzed and compared between groups. Electrophysiological data in the CPT task indicated larger prefrontal positive activity and greater posterior negativity distribution prior to a motor response in the skilled athletes, while novices showed a significantly larger response-related P3 after a motor response in centro-parietal areas. A different effect occurred in the c-CPT task in which the novice athletes showed strong prefrontal positive activity before a motor response and a large response-related P3, while in skilled athletes, the prefrontal activity was absent. We propose that during the CPT, skilled athletes were able to allocate two different but related processes simultaneously according to CPT demand, which requires controlled attention and controlled motor responses. On the other hand, in the c-CPT, skilled athletes showed better cue facilitation, which permitted a major economy of resources and “automatic” or less controlled responses to relevant stimuli. In conclusion, the present data suggest that motor expertise enhances neural flexibility and allows better adaptation of cognitive control to the requested task.
