abstract = {Physical capacity and coordination cannot alone predict success in team sports such as soccer. Instead, more focus has been directed towards the importance of cognitive abilities, and it has been suggested that executive functions (EF) are fundamentally important for success in soccer. However, executive functions are going through a steep development from adolescence to adulthood. Moreover, more complex EF involving manipulation of information (higher level EF) develop later than simple executive functions such as those linked to simple working memory capacity (Core EF). The link between EF and success in young soccer players is therefore not obvious. In the present study we investigated whether EF are associated with success in soccer in young elite soccer players. We performed tests measuring core EF (a demanding working memory task involving a variable n-back task; dWM) and higher level EF (Design Fluency test; DF). Color-Word Interference Test and Trail Making Test were performed on an exploratory level as they contain a linguistic element. The lower level EF test (dWM) was taken from CogStateSport computerized concussion testing and the higher level EF test (DF) was from Delis-Kaplan Executive Function System test battery (D-KEFS). In a group of young elite soccer players (n = 30; aged 12\textendash19 years) we show that they perform better than the norm in both the dWM (+0.49 SD) and DF (+0.86 SD). Moreover, we could show that both dWM and DF correlate with the number of goals the players perform during the season. The effect was more prominent for dWM (r = 0.437) than for DF (r = 0.349), but strongest for a combined measurement (r = 0.550). The effect was still present when we controlled for intelligence, length and age in a partial correlation analysis. Thus, our study suggests that both core and higher level EF may predict success in soccer also in young players. [ABSTRACT FROM AUTHOR]},

abstract = {Background Diagnosis threat is a psychosocial factor proposed to contribute to poor cognitive outcomes following mild traumatic brain injury (mTBI). The current research explored diagnosis threat impact on objective and subjective cognitive performance in a "high risk" population of athletes. Two possible moderators of diagnosis threat - injury beliefs and suggestibility - were also investigated. Method Seventy-six participants with a history of mTBI were recruited through sports clubs and randomized to a months threat group (instructions drew attention to mTBI history) or a control group (no mention of mTBI). They completed a battery of neuropsychological tests and questionnaires regarding day-to-day cognitive abilities. Measures of depression, anxiety, illness beliefs and suggestibility were also collected. Results No significant group differences were found on any neuropsychological tasks, nor on self-report of cognitive difficulties. Illness beliefs were not found to play a moderating role in general, although the majority of the study sample did not report negative mTBI beliefs and expectations: concern about the consequences of injury was associated with weaker performance on one test, WAIS-III Digit Span performance. Suggestibility was also found to have a significant affect on this test. Conclusions Diagnosis threat did not appear to have a marked affect on objective or subjective cognitive performance after mTBI in athletes. Differing injury beliefs between the study's athlete population and the general population is a possible explanation for different findings in the area.

abstract = {The long-term consequences of repetitive head impacts have been described since the early 20th century. Terms such as punch drunk and dementia pugilistica were first used to describe the clinical syndromes experienced by boxers. A more generic designation, chronic traumatic encephalopathy (CTE), has been employed since the mid-1900s and has been used in recent years to describe a neurodegenerative disease found not just in boxers but in American football players, other contact sport athletes, military veterans, and others with histories of repetitive brain trauma, including concussions and subconcussive trauma. This article reviews the literature of the clinical manifestations of CTE from 202 published cases. The clinical features include impairments in mood (for example, depression and hopelessness), behavior (for example, explosivity and violence), cognition (for example, impaired memory, executive functioning, attention, and dementia), and, less commonly, motor functioning (for example, parkinsonism, ataxia, and dysarthria). We present proposed research criteria for traumatic encephalopathy syndrome (TES) which consist of four variants or subtypes (TES behavioral/mood variant, TES cognitive variant, TES mixed variant, and TES dementia) as well as classifications of 'probable CTE' and 'possible CTE'. These proposed criteria are expected to be modified and updated as new research findings become available. They are not meant to be used for a clinical diagnosis. Rather, they should be viewed as research criteria that can be employed in studies of the underlying causes, risk factors, differential diagnosis, prevention, and treatment of CTE and related disorders. © 2014 Montenigro et al.; licensee BioMed Central Ltd.},

The goal was to examine the effect of different physiological states on the electrophysiological data. As expected, a larger P3b ERP component was observed in response to attended infrequent events. Strenuous exercise did not differentially alter the amplitude or latency of the brain response during an attention task. This study reports a novel application of ERPs as a potential additional measure of the neurocognitive state that can be assessed on the sideline of a sporting event.

In the present study, 13 students with self-reported concussion (MHI group: M time since injury = 8 years) and 10 controls were matched for age, sex, education, and a variety of cognitive, physical and emotional complaints. Controls outperformed the MHI group on the Digit Symbol substitution task and on a difficult dual task involving tone discrimination and visual working memory. Additionally, controls exhibited larger P300 amplitudes on both an easy and a difficult auditory discrimination task. A combination of electrophysiological, neuropsychological and self-report indices predicted group membership (MHI vs. control) with 88% accuracy. The present results, coupled with previous work, offer preliminary evidence that the combination of event-related potentials and demanding behavioral measures might reveal long-lasting, subtle cognitive problems associated with MHI. These findings may challenge existing notions of complete recovery after MHI. (PsycINFO Database Record (c) 2016 APA, all rights reserved)},

abstract = {Physical capacity and coordination cannot alone predict success in team sports such as soccer. Instead, more focus has been directed towards the importance of cognitive abilities, and it has been suggested that executive functions (EF) are fundamentally important for success in soccer. However, executive functions are going through a steep development from adolescence to adulthood. Moreover, more complex EF involving manipulation of information (higher level EF) develop later than simple executive functions such as those linked to simple working memory capacity (Core EF). The link between EF and success in young soccer players is therefore not obvious. In the present study we investigated whether EF are associated with success in soccer in young elite soccer players. We performed tests measuring core EF (a demanding working memory task involving a variable n-back task; dWM) and higher level EF (Design Fluency test; DF). Color-Word Interference Test and Trail Making Test were performed on an exploratory level as they contain a linguistic element. The lower level EF test (dWM) was taken from CogStateSport computerized concussion testing and the higher level EF test (DF) was from Delis-Kaplan Executive Function System test battery (D-KEFS). In a group of young elite soccer players (n = 30; aged 12\textendash19 years) we show that they perform better than the norm in both the dWM (+0.49 SD) and DF (+0.86 SD). Moreover, we could show that both dWM and DF correlate with the number of goals the players perform during the season. The effect was more prominent for dWM (r = 0.437) than for DF (r = 0.349), but strongest for a combined measurement (r = 0.550). The effect was still present when we controlled for intelligence, length and age in a partial correlation analysis. Thus, our study suggests that both core and higher level EF may predict success in soccer also in young players. [ABSTRACT FROM AUTHOR]},

abstract = {Background Diagnosis threat is a psychosocial factor proposed to contribute to poor cognitive outcomes following mild traumatic brain injury (mTBI). The current research explored diagnosis threat impact on objective and subjective cognitive performance in a "high risk" population of athletes. Two possible moderators of diagnosis threat - injury beliefs and suggestibility - were also investigated. Method Seventy-six participants with a history of mTBI were recruited through sports clubs and randomized to a months threat group (instructions drew attention to mTBI history) or a control group (no mention of mTBI). They completed a battery of neuropsychological tests and questionnaires regarding day-to-day cognitive abilities. Measures of depression, anxiety, illness beliefs and suggestibility were also collected. Results No significant group differences were found on any neuropsychological tasks, nor on self-report of cognitive difficulties. Illness beliefs were not found to play a moderating role in general, although the majority of the study sample did not report negative mTBI beliefs and expectations: concern about the consequences of injury was associated with weaker performance on one test, WAIS-III Digit Span performance. Suggestibility was also found to have a significant affect on this test. Conclusions Diagnosis threat did not appear to have a marked affect on objective or subjective cognitive performance after mTBI in athletes. Differing injury beliefs between the study's athlete population and the general population is a possible explanation for different findings in the area. This and other sources of potential variation in the affect of diagnosis threat are discussed. © 2016 Crown copyright 2016.},

abstract = {The long-term consequences of repetitive head impacts have been described since the early 20th century. Terms such as punch drunk and dementia pugilistica were first used to describe the clinical syndromes experienced by boxers. A more generic designation, chronic traumatic encephalopathy (CTE), has been employed since the mid-1900s and has been used in recent years to describe a neurodegenerative disease found not just in boxers but in American football players, other contact sport athletes, military veterans, and others with histories of repetitive brain trauma, including concussions and subconcussive trauma. This article reviews the literature of the clinical manifestations of CTE from 202 published cases. The clinical features include impairments in mood (for example, depression and hopelessness), behavior (for example, explosivity and violence), cognition (for example, impaired memory, executive functioning, attention, and dementia), and, less commonly, motor functioning (for example, parkinsonism, ataxia, and dysarthria). We present proposed research criteria for traumatic encephalopathy syndrome (TES) which consist of four variants or subtypes (TES behavioral/mood variant, TES cognitive variant, TES mixed variant, and TES dementia) as well as classifications of 'probable CTE' and 'possible CTE'. These proposed criteria are expected to be modified and updated as new research findings become available. They are not meant to be used for a clinical diagnosis. Rather, they should be viewed as research criteria that can be employed in studies of the underlying causes, risk factors, differential diagnosis, prevention, and treatment of CTE and related disorders. © 2014 Montenigro et al.; licensee BioMed Central Ltd.},
