Hockey youth in Canada: Parents' and coaches' beliefs towards the half-ice game model for U9 hockey.

Despite the advantages of small area games in youth sport, some challenges remain regarding the implementation of the half-ice gameplay model in Canada. In youth sport, establishing a good line of communication between parents and coaches is a crucial step for a positive environment. The purpose of this study is to provide further knowledge on the mechanisms associated with parents' and coaches' perceptions regarding the half-ice model in Canada. Data came from a national survey distributed across Canada (N = 6 372). Parents and coaches completed questionnaires that assessed attitudes, norms and perceived facilitators-obstacles to half-ice hockey. Parents-coaches' preferences towards the playing format and sociodemographic variables were also measured. Structural equation modelling was performed to verify associations between each variable. Beliefs were a key factor in parents-coaches' preferences regarding the playing format. Previous sport background and knowledge about half-ice hockey were associated with favorable predispositions. Hockey associations administrators should consider parents and coaches' predispositions in program implementation and should design promotional campaigns adapted to their members' predispositions towards half-ice hockey. This research underlines the key factors to consider in successful program implementation in youth sport.

Psychological characteristics of developing excellence in talented female field hockey players.

Psychological Characteristics of Developing Excellence (PCDEs) are a range of psychological factors that play a key role in the realisation of potential. We examined PCDE profiles across a female national talent development field hockey programme in North America. Two-hundred-and-sixty-seven players completed the Psychological Characteristics of Developing Excellence Questionnaire version 2 (PCDEQ-2) prior to the competitive season. One-hundred-and-fourteen players were classified as juniors (under-18) and 153 as seniors (over-18). Eighty-five players were classified as non-selected (not-selected to their age-group national team), and 182 as selected (selected to their age-group national team). A MANOVA showed multivariate differences based on age, selection status and their interaction, within this already homogenous sample, suggesting that sub-groups within this sample vary depending on their overall PCDE profiles. ANOVA showed differences in imagery and active preparation, perfectionist tendencies and clinical indicators between juniors and seniors. Furthermore, differences in imagery and active preparation, and perfectionist tendencies, were observed between selected and non-selected players. Subsequently, four individual cases were identified for further analysis based on their multivariate distance to the average PCDE profile. The use of the PCDEQ-2 at group- and particularly at individual-levels seems an important tool to support athletes as they navigate their development journey.

Experiences of Playing Volt Hockey With Focus on Well-Being According to Positive Emotion, Engagement, Relationships, Meaning, Achievement: An Interview Study.

Volt hockey is a team sport developed for persons with physical disabilities, but its influence on well-being is unknown. Elements of well-being have been described as positive emotions, engagement, relationships, meaning, and achievement constituting a theoretical framework referred to as PERMA. The purpose of this study was to describe how well-being according to PERMA is reflected in the experiences of playing volt hockey. Data were collected through focus group and individual interviews including 21 players. A deductive analysis was conducted using the elements in PERMA as preexisting main categories with an additional main category, named resources needed. Findings showed that all five elements constituting well-being according to PERMA were reflected in the experiences of playing volt hockey. In addition, players emphasized the importance of having the resources needed to play volt hockey. In conclusion, having the opportunity to enjoy playing volt hockey enabled the players to flourish and experience feelings of subjective well-being.

A Cross-Sectional Decision-Making Approach to Inform Neuropsychological Battery Development in Professional Hockey.

OBJECTIVE: Neuropsychologists commonly use a large battery of tests to inform clinical decisions. Decision analysis can be used to determine which individual tests play a role in the decision-making process. The objective of this project was to conduct quantitative and qualitative decision analysis of decisions by team neuropsychologists with professional hockey players being evaluated as part of the National Hockey League (NHL)/NHL Players Association Concussion Protocol. METHOD: We extracted neuropsychological data from an NHL clinical program database. Team neuropsychologists evaluated concussed players using a hybrid neuropsychological test battery. The neuropsychologists then determined whether players were experiencing concussion-related cognitive difficulties. Logistic regression was used to examine which tests accounted for unique variance in the decision-making process. We also conducted a survey of NHL neuropsychologists, asking them to rate the usefulness of each test in the battery. RESULTS: Five of the fifteen measures accounted for unique variance in team neuropsychologists' decisions, including the ImPACT Verbal Memory Composite, Visual Motor Composite, Reaction Time Composite, Symptom Score, and Brief Visuospatial Memory Test-Revised Delayed Recall. Notable discrepancies were uncovered between quantitative indications of usefulness and self-reported qualitative perceptions of test usefulness when making decisions. Qualitatively, clinicians reported that the Hopkins Verbal Learning Test-Revised, Symbol Digit Modalities Test, ImPACT Reaction Time, and Color Trails 2 were the most useful tests when making decisions. CONCLUSIONS: Along with validation studies, decision analysis can be used as part of a comprehensive evaluation process to inform the development of best-practice batteries for use among athletes with sports concussion.

"Beyond the Rink": A Multilevel Analysis of Social Identity Behaviors Captured Using the Electronically Activated Recorder.

This study used ecological sampling methods to examine associations between youth athletes' experiences receiving and engaging in behaviors indicative of in-group ties, cognitive centrality, and in-group affect (i.e., social identity) during a 3-day competitive ice hockey tournament. Forty-five youth (Mage = 12.39 years; SDage = 1.14 years; 94% male) from nine teams wore an electronically activated recorder that captured brief (50-s) audio observations throughout the tournament. Participants also completed daily diary questionnaires for each day of competition. Multilevel structural equation modeling demonstrated that athletes were more likely to engage in behaviors indicative of in-group affect and cognitive centrality on days when they received as higher-than-average frequency of behaviors indicative of cognitive centrality from teammates, coaches, and parents. The findings suggest that when team members interact in ways that demonstrate they are thinking about their team, they influence fellow members to behave in ways that promote a sense of "us."

The absence of fans removes the home advantage associated with penalties called by National Hockey League referees.

The COVID-19 pandemic has had a major impact on professional sports, notably, forcing the National Hockey League to hold its 2020 playoffs in empty arenas. This provided an unprecedented opportunity to study how crowds may influence penalties awarded by referees in an ecological context. Using data from playoff games played during the COVID-19 pandemic and the previous 5 years (n = 547), we estimate the number of penalties called by referees depending on whether or not spectators were present. The results show an interaction between a team's status (home; away) and the presence or absence of crowds. Post-hoc analyses reveal that referees awarded significantly more penalties to the away team compared to the home team when there is a crowd present. However, when there are no spectators, the number of penalties awarded to the away and home teams are not significantly different. In order to generalize these results, we took advantage of the extension of the pandemic and the unusual game setting it provided to observe the behavior of referees during the 2020-2021 regular season. Again, using data from the National Hockey League (n = 1639), but also expanding our sample to include Canadian Hockey League games (n = 1709), we also find that the advantage given to the home team by referees when in front of a crowd fades in the absence of spectators. These findings provide new evidence suggesting that social pressure does have an impact on referees' decision-making, thus contributing to explain the phenomenon of home advantage in professional ice hockey.

Mortality from mental disorders and suicide in male professional American football and soccer players: A meta-analysis.

OBJECTIVE: To determine the risk of mortality from mental disorders and suicide in professional sports associated with repeated head impacts. METHODS: A systematic search was performed in PubMed, Web of Science, Scopus, and SPORTDiscus (since inception to June 8, 2021) to find studies comparing the incidence of mortality from mental disorders or suicide in former or active professional athletes of sports characterized by repeated head impacts vs athletes with no such exposure or the general non-athletic population. RESULTS: Seven retrospective studies of moderate-to-high quality that included data from boxers and from basketball, ice hockey, soccer, and National Football League (NFL) players, respectively (total = 27 477 athletes, 100% male) met all inclusion criteria. Former male NFL players (n = 13 217) had a lower risk of mortality from mental disorders (standard mortality rate [SMR] = 0.30; 0.12-0.77; p = 0.012) and suicide (SMR = 0.54; 0.37-0.78; p < 0.001) than the general population. This finding was also corroborated in male soccer players (n = 13,065; SMR = 0.55; 0.46-0.67; p < 0.001). Male athletes participating in sports associated with repeated head impacts (n = 18,606) had also a lower risk of all-cause, cardiovascular disease (CVD), and cancer mortality (all p < 0.01) than the general population. CONCLUSIONS: Participation of male athletes in American football or soccer at the professional level might confer a certain protective effect against mortality from mental disorders or suicide, besides its association with a lower risk of all-cause, CVD, or cancer-related mortality.

Detrimental effects of prior self-control exertion on subsequent sporting skill performance.

The prior exertion of self-control has previously been shown to negatively affect physical performance, yet the effects on complex sporting skill performance have not been examined. Therefore, this study examined whether prior self-control exertion influences performance on a field hockey task, alongside measuring plasma cortisol concentration and attention as potential mechanisms to explain any effects. Following familiarization, 13 male hockey players (20 ± 1 years) participated in a randomized, order-balanced, crossover design. For the manipulation of self-control, participants completed an incongruent (self-control exertion trial) or a congruent (control trial) Stroop task. Skill performance was assessed using a field hockey skills task. Capillary blood samples, for the determination of plasma cortisol concentration, were taken at baseline, post-Stroop task, and post-field hockey skills task. Cognitive tests of attention (RVIP and Flanker tasks) were completed following the field hockey skills task. Participants made more errors in the latter stages of the field hockey skills task following self-control exertion (trial*time interaction, p = 0.041). Participants also made more errors on the RVIP task following self-control exertion (p = 0.035); yet the time taken to complete the hockey skills task, performance on the flanker task, and plasma cortisol concentrations were unaffected (all p > 0.05). Overall, these findings suggest that prior self-control exertion has detrimental effects on subsequent sporting skill performance (more errors made on the field hockey task), which may be explained by poorer sustained attention (lower accuracy on the RVIP task). This suggests that athletes should aim to avoid self-control exertion before a competitive match to optimize performance.

Singing off the same hymn sheet? Examining coherence in a talent development pathway (part 1).

Although there is research available into successful Talent Development Environments (TDEs), the data mostly reflects TDEs in elite academies, national groups or in a single successful club. This literature provides insight into the positive characteristics that are commonplace in these effective TDEs. However, little is known about the TDE surrounding an entire amateur national organization where athletes regularly compete across multiple teams, simultaneously representing at both domestic and international level. Importantly this added complexity increases the number of stakeholders across the pathway (e.g., school, club, international) creating a need for coherence throughout the TDE. Additionally considering the lack of research relating to females in talent development, we were interested from a pragmatic view, in examining the TDE of an amateur national hockey organization where young female athletes must navigate the pathway while simultaneously playing on multiple teams, contending with various coaches and contexts. The results suggest that the TDE provides a long term development experience supplemented with a good support network across all contexts. However, the alignment of expectations across contexts and the quality preparation of athletes in this TDE requires more attention to facilitate effective holistic athlete development.

Eliminating buyer's remorse: An examination of the sunk cost fallacy in the National Hockey League draft.

The sunk cost effect describes the tendency to escalate one's commitment toward a certain endeavor, despite diminishing returns, as a consequence of irreversible resource expenditure that has already been made (Organ Behav Hum Decis Process. 1985;35:124). This effect has been observed in a number of professional sports leagues, wherein teams escalate their commitment toward players selected early in the draft, regardless of performance outcomes, due to large financial commitments invested in them (J Sports Econom. 2017;18:282; Adm Sci Q. 1995;40:474). This effect, however, has yet to be explored in the National Hockey League (NHL). The purpose of this study was to test for sunk cost effects in the NHL, by examining the relationship between draft order and playing time, while controlling for a myriad of confounding variables. Findings from our analyses provide support for the existence of this effect in the NHL, as first-round draftees were given significantly more playing time than their peers selected in the second round, regardless of injury, player relocation, penalties, or on-ice performance outcomes. We offer some plausible underlying mechanisms driving this effect. Furthermore, we suggest the observed effects have valuable implications for NHL talent development, given the importance of playing time on various aspects of expertise attainment.

The prediction of thriving in elite sport: A prospective examination of the role of psychological need satisfaction, challenge appraisal, and salivary biomarkers.

OBJECTIVES: To examine (i) whether levels of, and changes in, athletes' basic psychological need satisfaction (BPNS) and challenge appraisals predicted in-match thriving; and (ii) if salivary biomarkers could be defined that were related to thriving. DESIGN: Prospective study design. METHODS: Fifty-one elite male hockey players (Mage=24.94 years, SDage=4.73) completed questionnaires measuring their BPNS and challenge appraisals on seven consecutive days prior to a competitive match, as well as providing saliva samples immediately on waking, and then +0.5, +3, and +5.25h on the day of the match. Saliva was assayed for catabolic (i.e., cortisol) and anabolic (i.e., dehydroepiandrosterone [DHEA]) hormones. In-match thriving was assessed retrospectively using measures of subjective performance and well-being. RESULTS: Latent growth curve modelling showed pre-match levels of BPNS and challenge appraisals to positively predict thriving. Although not statistically significant, small and moderate negative associations were found for thriving with cortisol concentration (+5.25h sample) and total cortisol exposure across the morning of the match, respectively. DHEA concentration shared a small positive, yet non-significant, association with thriving. CONCLUSIONS: Athletes' pre-match levels of BPNS and challenge appraisal predict in-match thriving; thus, offering potential mechanisms through which both high-level performance and the experience of well-being can be facilitated. Furthermore, associations suggest that total cortisol exposure across the morning of the match, and cortisol and DHEA levels in pre-match samples may offer sport science and sports medicine practitioners potential biomarkers for thriving. Future research is required to substantiate this initial finding.

Effect of motor imagery on enjoyment in knee-injury prevention and rehabilitation training: A randomized crossover study.

OBJECTIVES: The novel MOTor Imagery to Facilitate Sensorimotor Re-Learning (MOTIFS) model takes a uniquely holistic approach by integrating mental and physical aspects into current training programs. The aim of this trial was to evaluate enjoyment of MOTIFS training as compared to Care-as-Usual (CaU) knee injury and/or rehabilitation training. The primary hypothesis was that enjoyment would be greater following MOTIFS training than CaU training. DESIGN: Block-randomized 2×2 cross-over trial. METHODS: Thirty athletes (18-31years, 50% women) currently or previously active in team ball sports, with no pain or injury preventing jump and/or directional changes. MOTIFS training integrates sport-specific experiences and equipment into physical exercises to increase individualized realism and meaning. The CaU condition included solely physical exercise. The main outcome was the Physical Activity Enjoyment Scale (PACES). Secondary outcomes included Self-Assessment Manikin (SAM; subscales Valence, Arousal, Dominance), Perceived exertion, pulse, duration, and movement quality. RESULTS: PACES scores were better following MOTIFS training than CaU (point estimate 24.67; 95% CI: 19.0; 30.3). Between-groups differences in SAM Valence (median 2, quartiles 1;3), Arousal (median 1, quartiles 0;2.25), and Dominance (median 0.5, quartiles 0;2), and RPE (median 1, quartiles -0.3;2), training duration (mean 5.34, 95% CI: -0.17; -0.73), and pulse (median 7.50, quartiles 0.25;16.75) were higher following MOTIFS training than CaU training. CONCLUSIONS: Results suggest that the MOTIFS model, which integrates simultaneous physical and psychological interventions, is a clinically plausible method of influencing enjoyment and other psychological outcomes. Further studies may explore effects of the MOTIFS principles on injury prevention and rehabilitation training.

Accuracy from the slot: Evaluating draft selections in the National Hockey League.

The National Hockey League (NHL) entry draft is a process wherein teams make sequential selections from a pool of eligible players. Given the young age of prospects, drafting requires long-term forecasting of future performance under a high level of uncertainty. This study assessed the selection accuracy across all seven rounds of the draft, as well as between lottery and non-lottery picks within the first round. NHL performance data were collected for all forwards (N = 956) and defensemen (N = 558) drafted between 2007 and 2014. In both groups, Kruskal-Wallis H tests conducted between draft rounds revealed a significant, relatively strong, overall effect of draft order on future performance. However, Mann-Whitney U post-hoc tests showed projecting future performance of forwards was only accurate in the first two rounds, while for defensemen, selection was only accurate in the first round. Moreover, forwards selected with lottery picks in the first round outperformed their non-lottery peers offensively but not defensively. As for defensemen, those selected with lottery picks did not differ from their non-lottery peers in offensive or defensive performance. Our findings highlight substantial inaccuracies in the NHL draft, particularly past the first two rounds of selection. We offer multiple possible explanations driving such inaccuracies that could form the basis for further work in this area.

Examining the impact of the Respect in Sport Parent Program on the psychosocial experiences of minor hockey athletes.

Models of positive youth development suggest that athletes may be influenced by parent education programmes; however, there is little research examining the impact of such programmes on athlete outcomes. This study examined the impact of the Respect in Sport Parent Program on athlete outcomes among minor hockey players over three years. This study consisted of cross-sectional and longitudinal online surveys measuring athletes' positive and negative developmental experiences, prosocial and antisocial behaviours, parental support and pressure, and sport enjoyment and commitment. Athletes completed at least one online survey during the study period (N = 366; 84.2% males; 14-19 years of age; M = 15.4 years), and 83 athletes completed multiple surveys for longitudinal analyses. Cross-sectional results comparing athletes in leagues adopting the programme at different time points indicated significant differences in prosocial behaviours towards teammates. Multilevel longitudinal analyses revealed improvements in athletes' antisocial behaviours towards opponents, initiative, goal setting, and cognitive skills over time, regardless of whether they were in a league that implemented the programme. However, athletes in leagues that implemented the programme during the study reported greater improvements in antisocial behaviours towards opponents, and there were trends with respect to improved personal and social skills. These findings provide suggestions to improve the delivery and impact of parent education programmes in youth sport.

El objetivo del presente estudio fue analizar el efecto de las variables contextuales del partido en la intervención del portero de hockey patines durante las faltas directas. Se realizó un estudio documental basado en la Ok Liga 2015-16 y fueron analizadas todas las faltas directas (n=637). Los datos fueron recogidos de las actas de juego de la Real Federación Española de Patinaje. Se analizaron las variables contextuales: minuto de partido, estado del marcador, momento de la temporada, importancia de la falta directa y localización del partido. Se realizó un análisis correlacional mediante la prueba chi cuadrado de Pearson para identificar la relación entre las variables del estudio y la eficacia del portero. Los resultados constataron que el minuto de partido presenta una relación significativa con la eficacia del portero (χ2= 17,665; Sig.=,04; p < ,05; w = ,167). un aumento de la frecuencia de faltas directas en los momentos finales, el 43,96% son lanzadas en los últimos 10 minutos de partido, y una mejora de la eficacia del portero en los momentos críticos (77,1%). Estos resultados pueden contribuir a una mejor comprensión de la importancia de los porteros en el resultado final de los partidos de hockey patines

The aim of the present study was to analyze the effect of the match's contextual variables on the roller hockey goalkeeper intervention during free hits. A documentary study based on the Ok Liga 2015-16 was carried out and all the direct free hit of this season were analyzed (n=637). The data were collected from the playing records of the Real Federación Española de Patinaje. The contextual variables analyzed in direct free hit were: the minute of the match, score status, season time, importance of the direct free hit and match location. A correlational analysis has been performed using the Pearson's chi-squared test to identify the relationship between contextual variables and goalkeeper's efficiency. The results show that the minute of the match has a significant relationship with the goalkeeper's efficiency (χ2= 17.665, Sig. =.04, p < .05; w = .167), an increase in the frequency of direct free hit in the final moments, 43.96% are thrown in the last 10 minutes of the game, and an improvement in the goalkeeper's efficiency in critical moments (77.1%). These results can contribute to a better understanding of the goalkeepers' importance in roller hockey matches result

Esses resultados podem contribuir para uma melhor compreensão da importância dos guarda-redes no resultado final dos jogos de hóquei em patins

Achieving a desired training intensity through the prescription of external training load variables in youth sport: More pieces to the puzzle required.

Identifying the external training load variables which influence subjective internal response will help reduce the mismatch between coach-intended and athlete-perceived training intensity. Therefore, this study aimed to reduce external training load measures into distinct principal components (PCs), plot internal training response (quantified via session Rating of Perceived Exertion [sRPE]) against the identified PCs and investigate how the prescription of PCs influences subjective internal training response. Twenty-nine school to international level youth athletes wore microtechnology units for field-based training sessions. SRPE was collected post-session and assigned to the microtechnology unit data for the corresponding training session. 198 rugby union, 145 field hockey and 142 soccer observations were analysed. The external training variables were reduced to two PCs for each sport cumulatively explaining 91%, 96% and 91% of sRPE variance in rugby union, field hockey and soccer, respectively. However, when internal response was plotted against the PCs, the lack of separation between low-, moderate- and high-intensity training sessions precluded further analysis as the prescription of the PCs do not appear to distinguish subjective session intensity. A coach may therefore wish to consider the multitude of physiological, psychological and environmental factors which influence sRPE alongside external training load prescription.

Adolescent hockey players' predispositions to adopt sport and exercise behaviours: An ecological perspective.

Organized sport yields many cognitive, social and physical benefits and is one of the most popular types of physical activity for children and adolescents. Despite the benefits of sports participation, a substantial proportion of adolescents fail to meet Canadian guidelines regarding physical activity. In this regard, it is relevant to understand the mechanisms underlying the adoption of various active behaviours. This study aims to identify the predisposing, enabling and reinforcing factors that potentially influence 4 categories of active behaviours using the Youth Physical Activity Promotion model (YPAP). Data was drawn from 416 male adolescent hockey players (Mage = 15.4; SD = 2) who completed a pre-validated questionnaire. Structural equation modeling and interaction analyses were performed to explain the contribution of each determinant. Findings reveal that there are different behavioural patterns based on the type of activity. The interaction between attitudes and environmental factors was a key predictor for each type of behaviour. Perceived competence was associated with more recreational activities, whereas the support of parents and coaches determined involvement in ice hockey. This study refined our understanding of physical activity participation among adolescents already involved in organized sports and emphasized the importance of considering multiple factors surrounding their environment. Several practical recommendations are made to improve young athletes' predisposition to practice physical activity in an organized sports setting.

History of Sport-Related Concussion and Long-Term Clinical Cognitive Health Outcomes in Retired Athletes: A Systematic Review.

BACKGROUND: Sport-related concussions (SRCs) are known to have short-term effects on cognitive processes, which can result in diverse clinical presentations. The long-term effects of SRC and repeated exposure to head impacts that do not result in SRC on specific cognitive health outcomes remain unclear. OBJECTIVES: To synthesize and appraise the evidence base regarding cognitive health in living retired athletes with a history of head-impact exposure or SRC. DATA SOURCES: A systematic search of the EMBASE, PsycINFO, MEDLINE/PubMed, CINAHL, Cochrane Central Register of Controlled Trials, and Web of Science databases was conducted from inception to April 2018 using common key words and medical subject headings related to 3 components: (1) the participant (eg, retired athlete), (2) the primary outcome measure (eg, cognitive test used), and (3) the secondary outcome measure (eg, history of sport concussion). STUDY SELECTION: Cross-sectional studies of living retired male or female athletes in which at least 1 cognitive test was used as an outcome measure were included. Two reviewers independently screened studies. DATA EXTRACTION: Data extraction was performed using Strengthening the Reporting of Observational Studies in Epidemiology guidelines. Methodologic quality was assessed independently by 2 reviewers using the Downs and Black tool. DATA SYNTHESIS: The search yielded 46 cross-sectional observational studies that were included in a qualitative synthesis. Most included studies (80%, n = 37) were published in the 5 years before our review. A large proportion of these studies (n = 20) included retired American National Football League players. The other research investigated professional, university, high school, and amateur retired athletes participating in sports such as American and Australian football, boxing, field and ice hockey, rugby, and soccer. The total sample consisted of 13 975 participants: 7387 collision-sport athletes, 662 contact-sport athletes, 3346 noncontact-sport athletes, and 2580 participants classified as controls. Compared with control participants or normative data, retired athletes displayed worse performance in 17 of 31 studies (55%) of memory, 6 of 11 studies (55%) of executive function, and 4 of 6 studies (67%) of psychomotor function and increased subjective concerns about cognitive function in 11 of 14 studies (79%). The authors of 13 of 46 investigations (28%) reported a frequency-response relationship, with poorer cognitive outcomes in athletes who had greater levels of exposure to head impacts or concussions. However, these results must be interpreted in light of the lack of methodologic rigor and moderate quality assessment of the included studies. CONCLUSIONS: Evidence of poorer cognitive health among retired athletes with a history of concussion and head-impact exposure is evolving. Our results suggest that a history of SRC may more greatly affect the cognitive domains of memory, executive function, and psychomotor function. Retired athletes appeared to have increased self-reported cognitive difficulties, but the paucity of high-quality, prospective studies limited the conclusions that could be drawn regarding a cause-and-effect relationship between concussion and long-term health outcomes. Future researchers should consider a range of cognitive health outcomes, as well as premorbid ability, in diverse samples of athletes with or without a history of concussion or head-impact exposure to delineate the long-term effects of sport participation on cognitive functioning.

Neuropsychological Assessment of Professional Ice Hockey Players: A Cross-Cultural Examination of Baseline Data Across Language Groups.

OBJECTIVE: Neuropsychological testing in sports has become routine across all levels of play. The National Hockey League (NHL) has conducted baseline neuropsychological assessment of all players since 1997. This study seeks to examine baseline differences among linguistically and culturally diverse groups within the NHL and to present comprehensive normative data for these groups. METHOD: Baseline data were obtained from 3,145 professional hockey players' baseline symptom reporting, neuropsychological test performance on a battery of traditional "paper and pencil" measures, and self-reported concussion history. In addition, 604 baseline post-injury paper and pencil evaluations were conducted the season following a concussion and 4,780 computerized baseline ImPACT administrations were obtained following the introduction of computerized testing. RESULTS: Normative data for paper and pencil tests and ImPACT are presented for the major language groups within the league: English, French, Swedish, Russian, Czech, Finnish, and German (ImPACT only). It was found that symptom reporting, the number of concussions sustained, and neuropsychological test results vary significantly based on a players' language of origin. This variability was also present when players were tested in their language of origin. CONCLUSIONS: This study provides insight into the significant baseline differences that exist among NHL players regarding symptoms, concussion history, and cognitive functioning. The findings are discussed with respect to the evaluation and management of NHL players who sustain concussion and more generally in the context of neuropsychological assessment in cross-cultural settings, including the importance of examining neuropsychological functioning using culturally specific norms.

Evaluación e intervención psicológica en jugadoras de hockey sobre hierba femenino / Evaluation and psychological intervention in female grass hockey players / Avaliação e intervenção psicológica em jogadoras de hóquei em grama

El objeto de este estudio de caso fue evaluar las habilidades psicológicas de jugadoras de hockey hierba, y, por otro lado, la eficacia de la participación en un programa de entrenamiento psicológico en las características psicológicas relacionadas con el rendimiento deportivo. Participaron 10 jugadoras de hockey de 16 a 26 años de la selección de hockey hierba femenino de categoría senior. La intervención psicológica se realizó en Montevideo-Uruguay, durante 16 sesiones a través de trabajo individualizado (voluntario) y trabajo grupal (obligatorio) con un enfoque cognitivo-conductual. La intervención estuvo formada por técnicas y estrategias como la reestructuración cognitiva; la autocaracterización; la técnica de la Rejilla de concentración y Stroop; habilidades de comunicación y de autoconocimiento; auto-registros conductuales; observaciones-confrontaciones e interpretaciones; y técnicas de relajación y visualización. Se administró el Cuestionario de Características Psicológicas relacionadas con el Rendimiento Deportivo en jugadores de fútbol (CPRD-f, Olmedilla, García y Martínez, 2007) antes y después de la intervención de 4 meses de duración. Los resultados indican que las habilidades psicológicas en estas deportistas son caracterizadas por niveles altos de autoconfianza; impermeabilidad a la evaluación del rendimiento; manejo de la ansiedad competitiva y de la atención-concentración. Aparecen diferencias significativas tras la intervención que favorecen la calma ante las diferentes situaciones relacionadas con la competición, con un aumento del manejo de la ansiedad competitiva. Se plantea la necesidad de transferir esta información a psicólogos del deporte que intervengan a jugadoras de hockey, facilitando la selección y ajuste de estrategias psicológicas específicas en los planes de entrenamiento con el objetivo de mantener y fortalecer sus habilidades psicológicas llegando a conseguir que se manifiesten al máximo nivel

The purpose of this pilot study was to evaluate the psychological skills of grass hockey players, and, on the other hand, the effectiveness of participation in a psychological training program on psychological characteristics related to athletic performance. Ten hockey players from 16 to 26 years old participated in the senior women's field hockey team. The psychological intervention was carried out during 16 sessions through individualized work (voluntary) and group. The intervention consisted of techniques and strategies such as cognitive restructuring; self-characterization; the technique of the concentration grid and Stroop; communication and self-knowledge skills; behavioral self-records; observations-confrontations and interpretations; and relaxation and visualization techniques. The CPRD-f (Olmedilla, García and Martínez, 2007) was administered before and after the 4-month intervention. The results indicate that the psychological skills in these athletes are characterized by high levels of self-confidence; impermeability to performance evaluation; management of competitive anxiety and attention-concentration. Significant differences appear after the intervention that favor calm against the different situations related to the competition. The need arises to transfer this information to sports psychologists who intervene hockey players, facilitating the selection and adjustment of specific psychological strategies in training plans with the aim of maintaining and strengthening their psychological skills, getting them to manifest themselves to the maximum level

O objetivo deste estudo de caso foi avaliar as habilidades psicológicas de jogadoras de hóquei na grama, assim como a efetividade durante a participação em um programa de treinamento baseado nas características psicológicas relacionadas com o desempenho esportivo. Dez jogadoras de hóquei entre 16 e 26 anos participaram da seleção feminina ha categoria sênior. A intervenção psicológica foi realizada em Montevidéu, Uruguai, por meio de 16 sessões, através de trabalho individualizado (voluntário) e trabalho em grupo (obrigatório) com uma abordagem cognitiva/comportamental. A intervenção foi realizada por técnicas com o emprego de estratégias como reestruturação cognitiva, autocaracterização, técnica da capacidade de concentração e habilidades de comunicação e autoconhecimento, registros autocomportamentais, observações, confrontos e interpretações e técnicas de relaxamento e visualização. Foi aplicado um questionário das características psicológicas relacionadas ao desempenho esportivo em jogadores de futebol (CPRD-f, Olmedilla, García y Martínez, 2007) antes e após a intervenção de quatro meses. Os resultados indicam que as habilidades psicológicas desses atletas são caracterizadas por altos níveis de autoconfiança e permeabilidade à avaliação do desempenho da gestão competitiva da ansiedade e concentração. Diferenças significativas apareceram após a intervenção que favorecem a calma diante das diferentes situações relacionadas à competição, com um aumento no gerenciamento da ansiedade competitiva. Surge a necessidade então de transferir essas informações aos psicólogos esportivos que intervêm junto aos jogadores de hóquei, facilitando a seleção e o ajuste de estratégias específicas nos planos de treinamento como objetivo de manter e fortalecer suas habilidades psicológicas, fazendo com que elas se manifestem no mais alto nível
