Early sport involvement in young Portuguese basketball players

The purpose of this study was to examine the quantity and type of sporting activities undertaken by young Portuguese basketball players in early stages of athletic development. 750 basketball players aged between 12 and 16 years served as participants, grouped by sex and competitive level. The Skilled group comprised players representing the 9 highly ranked regional teams (n=378) while the Less-skilled group comprised the players representing the remaining 9 regional teams (n=372). All the participants filled out a previously validated questionnaire based on retrospective information linked to the training activities experienced throughout their involvement in sport. Results suggest that the majority of the players started practicing sports preferentially between 6 and 10 years. However, a significant number of players reported a later start, between 11 and 14 years of age. The pattern of sport involvement confirmed important divergences in the path reported by the players by the team's competitive level. The major findings of this study confirmed that players representing the highly ranked teams demonstrated a tendency to extend their training activities during longer periods during the week and throughout each season.     

Cognitive advantage in sport: the nature of perceptual structures

To extend and clarify the nature of the perceptual processes used by sport experts to perceive schematic sport information, two experiments used schematic football diagrams that varied in structure (structured vs. unstructured) and complexity (complex vs. easy). The primary objective was to examine and characterize the nature of the perceptual structures (chunks) that are initially encoded, stored, and subsequently retrieved. In Experiment 1, compared with nonexperts, experts recalled larger perceptual structures following the initial stimulus presentation of structured stimuli only, replicating the recall findings of previous research in other skill domains. Experiment 2 used a long-term memory recognition task and a sorting task. Experts had superior recall and recognition of structured stimuli only, along with more discriminating sorting criteria of perceptual structures within long-term memory. This suggests that experts possess a highly refined semantic network or organized, structured schematic information. This research extends and clarifies the similarities between the perceptual processes of experts in sport (i.e., football) and experts in skill domains that require obvious cognitive involvement (i.e., chess). The results are discussed with reference to the perceptual and conceptual chunking hypotheses. It is proposed that sport experts' knowledge of a conceptual category enables them to retrieve elements using a "generate-and-test process."     

Does Grit Influence Sport-Specific Engagement and Perceptual-Cognitive Expertise in Elite Youth Soccer?

We examined whether soccer players who score low and high on the personality trait grit can be differentiated based on their sport-specific engagement and perceptual-cognitive expertise. Findings revealed that grittier players accumulated significantly more time in sport-specific activities including competition, training, play, and indirect involvement. Moreover, there was a significant main effect for performance on the perceptual-cognitive skills tests across groups, with grittier players performing better than less gritty players on the assessments of decision making and situational probability. The findings are the first to demonstrate a potential link between grit, sport-specific engagement, and perceptual-cognitive expertise.     

Effects of adult age and level of skill on the ability to cope with high-stress conditions in a precision sport

Younger and older highly skilled and moderately skilled miniature golf players were studied in training and competition. All of the players showed an increase of heart rate and rated anxiety from training to competition. A performance decline in competition was observed for both older players and less accomplished players. Results from a cognitive task (incidental recall of shots) suggest that older players are less proficient in coping with the high-stress conditions in competition, due to an age-related decline in task-relevant cognitive abilities.     

Visual span and change detection in soccer: An expertise study

There is evidence to suggest that sports experts are able to extract more perceptual information from a single fixation than novices when exposed to meaningful tasks that are specific to their field of expertise. In particular, Reingold et al. (2001) showed that chess experts use a larger visual span including fewer fixations when compared to their less skilled counterparts. The aim of the present study was to examine whether also in a more complex environment, namely soccer, skilled players use a larger visual span and fewer fixations than less skilled players when attempting to recognise players’ positions. To this end, we combined the gaze-contingent window technique with the change detection paradigm. Results seem to suggest that skilled soccer players do not use a larger visual span than less skilled players. However, skilled soccer players showed significantly fewer fixations of longer duration than their less skilled counterparts, supporting the notion that experts may extract more information from a single glance.     

Retention of Quiet Eye in Older Skilled Basketball Players

There is mounting research to suggest that cognitive and motor expertise is more resistant to age-related decline than more general capacities. The authors investigated the retention of skills in medium-aged skilled (n = 14) and older-aged skilled (n = 7) athletes by comparing them with medium-aged less skilled (n = 15) and older-aged less skilled (n = 15) participants. Participants performed basketball free throws and dart throws as a transfer task under standardized conditions. Motor performance (accuracy) and perceptual performance (quiet eye) were examined across the four groups. There were significant differences between skill groups and age groups in throwing accuracy on both throwing tasks. Skilled players outperformed less skilled and medium-aged players outperformed older-aged players in basketball and dart throws. There were no significant differences in quiet eye duration across the skill or age groups in either task. These results indicate expertise in a perceptual motor task such as the basketball free throw can be retained in older athletes and that present models of skill maintenance should be re-evaluated to consider the issue of transfer.     

Assessing the Relationship Between Youth Sport Participation Settings and Creativity in Adulthood

This article presents an assessment of the relative influences of time spent participating in organized sports and informal sports during childhood with respect to the development of general creativity. In this study, 99 upper-division undergraduate and graduate students completed a comprehensive childhood leisure activities questionnaire and the Abbreviated Torrance Test for Adults. According to the results of the joint generalized least-squares regression analysis, hours spent in organized sport settings was negatively related to creativity as an adult; time spent in unstructured sport settings was found to be positively related to adult creativity. The findings also point to the importance of balancing participation across organized and unstructured settings. The most creative individuals in the sample were those who spent roughly half of their sport participation time in each setting, as opposed to individuals with below-average creativity, who spent upwards of 3/4 of their sport participation time in organized settings. Therefore, fostering creative development through sport may not require a dramatic reorientation from current youth sport development models, but only a shift toward a more balanced distribution of time spent playing in both organized and unstructured settings. Future experiments are needed to test this relationship.     

Gritting One’s way to success – Grit explains skill in elite youth soccer players beyond (deliberate) practice

Practice is one of the most important predictors of skill. To become an expert, performers must engage in practice for a prolonged time to develop the psychological characteristics necessary for outstanding performance. Deliberate practice (DP), that is focused repetitive activities with corrective feedback, is particularly beneficial for skill development. The amount of accumulated DP differentiates experts and novices. However, the predictive strength of DP weakens considerably when it comes to differentiating between differently skilled experts, leaving a way clear for other non-practice related factors to exercise their influence. In this paper, we demonstrate using a large sample (388) of elite youth soccer players that one such factor, the personality trait of grit, predicts expertise level both directly and indirectly. Grittier players accumulated more time in coach-led team practice, the activity, which is arguably closest to DP in team sports, which in turn predicted the skill level. Other practice activities, such as self-led training or playing with peers, were not predictive of skill level, neither were they influenced by grit. Grit, however, continued to exert a direct positive influence on the skill level of players even after accounting for the hours of DP accumulated. Overall, a standard deviation of change in the grit score resulted in at least a third of standard deviation improvement in skill. Our findings highlight the need for the inclusion of additional factors in theoretical frameworks in situations where the predictive power of traditional expertise factors, such as practice, is limited.     

Socialization influences of collegiate female athletes: A tale of two decades

Over the past decade, sport participation opportunities for females have increased dramatically. The purposes of this study were to compare perceptions of encouragement and support from socializing agents for: (a) female collegiate volleyball players competing during the 1979 and 1989 seasons, and (b) female collegiate athletes and female and male nonathletes. Female athletes (n= 345), female nonathletes (n= 128), and male nonathletes (n= 88) completed a questionnaire to assess significant others' influence on sport involvement during childhood, adolescence, and college years. Results indicated that interest and encouragement by parents, older siblings, and friends significantly increased for female athletes over the past 10 years during one or more developmental period. Discriminant analyses revealed that female athletes perceived stronger influences from mother, siblings, friends, and coaches than did male and female nonathletes. These results demonstrate that female athletes received greater social support than their peers a decade earlier, and these influences were significantly different than male and female nonathletes. This study was supported by a grant awarded to the first author by the Center for the Study of Women in Society, University of Oregon, Eugene.     

Skilled players’ and novices’ difficulty anticipating left- vs. right-handed opponents’ action intentions varies across different points in time

A left-handers’ performance advantage in interactive sports is assumed to result from their relative rarity compared to right-handers. Part of this advantage may be explained by athletes facing difficulties anticipating left-handers’ action intentions, particularly when anticipation is based on kinematic cues available at an early stage of an opponent’s movement. Here we tested whether the type of volleyball attack is predicted better against right- vs. left-handed opponents’ movements and whether such handedness effects are evident at earlier time points in skilled players than novices. In a video-based experiment volleyball players and novices predicted the type of shot (i.e., smash vs. lob) of left- and right-handed volleyball attacks occluded at six different time points. Overall, right-handed attacks were better anticipated than left-handed attacks, volleyball players outperformed novices, and performance improved in later occlusion conditions. Moreover, in skilled players the handedness effect was most pronounced when attacks were occluded 480 ms prior to hand-ball-contact, whereas in novices it was most evident 240 ms prior to hand-ball-contact. Our findings provide further evidence of the effect of an opponent’s handedness on action outcome anticipation and suggest that its occurrence in the course of an opponent’s unfolding action likely depends on an observers’ domain-specific skill.     

Staying in or moving away from structured activities: Explanations involving parents and peers

Adolescent participation in structured activities, meaning those with adult leaders, regular meetings, and skill-building activities, is related to good adjustment. Participation in unstructured, unsupervised, peer-oriented activities is related to poor adjustment. Structured activity participation is high in early adolescence and then declines, raising the question of why youths leave structured activities. The authors examined explanations involving parents and peers. They used longitudinal data from 861 youths (ages 13-17 years). Results showed that, compared with youths who stayed in structured activities, those who switched to hanging out on the streets were less likely to have peers in structured activities and had less positive feelings about the home context and more negative interactions with parents. In addition, delinquency predicted switching to hanging out in the streets and never joining structured activities in the first place. The results concerning parents support a theoretical explanation of how parents might unintentionally affect youths' leisure choices. Furthermore, the authors found some indications that positive feelings at home might protect youths who switch from structured activities to hanging out on the streets from increases in delinquency.     

Understanding enjoyment in youth sport: A developmental perspective

ObjectivesHistorically, the youth sport emotional response literature focused mainly on stress and enjoyment. Although research on these emotional responses has been significant, no systematic examination of these responses from a developmental perspective has been undertaken and therefore, developmental influence and implications for competitive youth sport are largely unknown. To begin to address this issue, the present study examined the developmental progression of sources of enjoyment among youth sport participants.DesignA multivariate analysis of variance (MANOVA) was used to examine the developmental differences in sources of enjoyment among younger (under 11 years) and older (over 11 years) children participating in individual and team sports.MethodsParticipants (n=152) aged 8–15 years were categorized into groups of younger and older children based on underlying cognitive-developmental criteria. Self-report measures of enjoyment, sources of enjoyment, perceived sport competence, and task and ego goal orientation were recorded.ResultsOlder children reported significantly greater enjoyment and other-referenced competency and recognition than younger children. Although all sources of enjoyment predicted enjoyment among younger children, no single source added a unique proportion of variance to the model. Competitive excitement (CE) and other-referenced competency and recognition significantly predicted enjoyment among older children. Team sport participants reported significantly greater self-referenced competency (SRC), affiliation with peers (AP), competitive excitement (CE), positive parental involvement (PPI) and enjoyment compared with individual sport participants. Finally, aligned with previous research, task orientation and perceived competence significantly predicted enjoyment.ConclusionsThe results of the present study underline the importance of understanding the developmental progression of sources of enjoyment among children and adolescents in sport. Furthermore, consideration should also be given to the nature of the sport (team or individual) children participate in for long-term enjoyment and commitment to sport.     

Verbal aggressiveness and state anxiety of volleyball players and coaches

The purpose of the present study was to examine the relation of verbal aggressiveness and state anxiety (somatic, cognitive, and self-confidence) in sports settings based on the ratings by volleyball coaches and their athletes. The sample consisted of volleyball athletes (n=208; 98 men and 110 women) and their coaches (n=20; 16 men and 4 women). Analysis showed that male volleyball players rated somatic anxiety higher and were more affected by the verbal aggressiveness of their coaches than female volleyball players. No mean differences were significant for male and female coaches on somatic or cognitive anxiety, self-confidence, or verbal aggressiveness. Also, correlation between subscale scores for male and female volleyball players and coaches was found. The correlations of verbal aggressiveness with self-confidence and anxiety were positive for these athletes, leading them to better behavior. This relationship needs further examination in sport settings.     

Individual differences in attentional capability are linked to creative decision making

There is a link between visual attention and creativity concerning the generation of rare and flexible decisions/solutions. However, the relationship between individual differences in attentional capability and creative decision making has not yet been investigated in detail. The current study scrutinized this link in a sport‐specific divergent thinking task including videos of real game situations and compared performances between football players being divided into two different expertise levels (expert and amateur football players). We conducted a multiple linear regression analysis to assess whether attentional capability along the attentional focus’ meridians (horizontal, vertical, diagonal) and participants’ expertise level predict creative decision making. The attentional capability along the horizontal meridian of participants’ attentional focus and participants’ expertise level emerged as positive predictors. The findings provide evidence of a relationship between football players’ spatial distribution of attention that match the demands of their sport and an expertise advantage in sport‐specific creative decision making. Implications are not only important for sports, but also for all areas in which spatial attention is required in order to generate unusual solutions.     

The 5C’s Model of Successful Partnerships in Elite Beach Volleyball Dyads

An athlete–athlete partnership is a form of athletic dyad in which both members equally share power and responsibility. Although research on the coach–athlete relationship is prevalent, research on the unique interpersonal dynamics of athlete–athlete partnerships in elite sport is sparse, particularly in beach volleyball. The purpose of the present study was to explore the interpersonal components of successful, elite athlete–athlete beach volleyball partnerships through the lens of interdependence theory and Jowett and colleagues’ 3?+?1C’s theory of coach–athlete relationships. Interpretative Phenomenological Analysis was applied to semistructured interviews with four Olympic-level beach volleyball players (3 male, 1 female). Results revealed 5 higher order themes: (a) compatibility, (b) commitment, (c) complementarity, (d) coorientation, and (e) closeness, which became the key constructs in the proposed 5C’s model of the successful athlete–athlete partnership. Interpersonal awareness, interpersonal maturation, and context were identified as 3 overarching meta-themes, whereas interdependence connected all interpersonal components. For example, in consultation, increasing athlete individual and interpersonal awareness (e.g., in the areas of personal and dyadic philosophy, personal and shared values, and individual and dyadic coping) requires careful contextualization and thoughtful implementation. Future studies need to examine diverse samples of athlete–athlete dyads to advance interpersonal theory in sport and add to emerging theories of performance behavior and expertise in sport.

Lay Summary: Successful beach volleyball partnerships share a philosophy and commitment to their sport. Desired partners are supportive and adaptive, are compatible, depend on one another, and continually appraise and reflect on their relationship to grow as individuals and as teammates.     

The use of anticipatory visual cues by highly skilled tennis players

The authors examined 13 skilled and 12 novice tennis performers' ability to use visual information of an opponent's movement pattern to anticipate and respond. In Experiment 1, skilled and novice players anticipated the type of stroke and the direction in which the ball was hit in a highly coupled perception-action environment. Both groups of players correctly anticipated at greater than chance levels. Skilled players were significantly more accurate than novices with live and video displays but not with point-light displays. In Experiment 2, the reaction latencies of 10 expert performers were significantly faster when they returned balls hit by a live opponent than when they returned balls projected from a cloaked ball machine. The findings indicate that experts are able to use movement-pattern information to determine shot selection and to use that information to significantly reduce their response delay times. The findings are discussed in terms of perception-action coupling in time-stress activities.     

On the advantage of being left-handed in volleyball: further evidence of the specificity of skilled visual perception

High ball speeds and close distances between competitors require athletes in interactive sports to correctly anticipate an opponent's intentions in order to render appropriate reactions. Although it is considered crucial for successful performance, such skill appears impaired when athletes are confronted with a left-handed opponent, possibly because of athletes' reduced perceptual familiarity with rarely encountered left-handed actions. To test this negative perceptual frequency effect hypothesis, we invited 18 skilled and 18 novice volleyball players to predict shot directions of left- and right-handed attacks in a video-based visual anticipation task. In accordance with our predictions, and with recent reports on laterality differences in visual perception, the outcome of left-handed actions was significantly less accurately predicted than the outcome of right-handed attacks. In addition, this left-right bias was most distinct when predictions had to be based on preimpact (i.e., before hand-ball contact) kinematic cues, and skilled players were generally more affected by the opponents' handedness than were novices. The study's findings corroborate the assumption that skilled visual perception is attuned to more frequently encountered actions.     

Recognition accuracy by experienced men and women players of basketball

This study examined 30 experienced basketball players' recognition accuracy by sex, playing position (guard, forward, and center), and situations in the game of basketball. The study used a perceptual cognitive paradigm in which subjects viewed slides of structured and unstructured game situations and accurately recognized the presence or absence of the basketball. A significant difference in recognition accuracy by sex, players' position, and structure of the game situation was found. Male players' recognition accuracy was better than the female players'. The recognition accuracy of subjects who played guard was better than that of subjects who played forward or center. The players' recognition accuracy was more accurate when observing structured plays versus unstructured plays. The conclusion of this study suggested that experienced basketball players differ in their cognitive and visual searching processes by sex and player position within the sport of basketball.     

Perceived verbal aggressiveness of coaches in volleyball and basketball: a preliminary study

This study examined verbal aggressiveness of coaches as perceived by their athletes, 108 senior athletes (57 boys and 51 girls) ages 15-19 years. Participants were basketball players (56 athletes) and volleyball players (52 athletes) who completed questionnaires. The scale of verbal aggressiveness showed high internal consistency. A two-way analysis of variance, conducted using sex and sport as independent variables to examine interactions, yielded significant differences between adolescent volleyball and basketball athletes. Volleyball athletes had lower scores on the Verbal Aggressiveness Scale than basketball players. Research with larger samples and other sports is recommended.
