Perceptual visual skills in young highly skilled basketball players

A simple method was designed to evaluate visual abilities such as disance visual acuity, binocular horizontal visual field, simple and choice visual reaction times, and stereoscopic vision in skilled 11- to 13-yr.-old basketball players participating in a 15-day summer training camp. On a test battery, visual abilities were monitored in 473 players of the Spanish Basketball Federation over a 5-yr. period. The players showed outstanding scores on distance visual acuity and stereoscopic vision, and good visual reaction times and horizontal visual fields. When scores were compared by sex and age, significant differences on certain visual measures were observed. Many layers showed crossed eye-hand dominance. Visual screening programs may help promote visual health among junior basketball players and could be used for performance training.     

An especial skill in elite wheelchair basketball players

We aimed to investigate whether an especial skill is present in elite wheelchair basketball players when taking twenty shots with a regular basketball from five different distances (11 ft, 13 ft, 17 ft, & 19 ft) from the basket including the free throw line (15 ft). Twelve elite male basketball players participated. The results showed that as distance increased shot accuracy decreased in line with force by variability predictions for the 11 ft, 13 ft, 17 ft, & 19 ft distances. However, shot performance at the free throw line where players are more familiar with practicing free throw shots did not follow this trend. A linear regression line was drawn to predict performance at the free throw line based on nearer (11 ft & 13 ft) and farer (17 ft & 19 ft) distances to the basket, this was then compared to actual performance. A significant difference between actual and predicted scores was found (p < .05) supporting the presence of an especial skill. Significant positive correlations were found for the 11 ft and 17 ft distance, age, years of playing, and accumulated practice hours with performance at the 15 ft line (p < .05). These correlations imply the operation of generalization in the especial skill. This observation received support from applying a model in which shot accuracy as a function of distance was approximated by two regression lines.     

Specific effect of a cognitive-motor dual-task training on sport performance and brain processing associated with decision-making in semi-elite basketball players

ObjectivesIn this study, we aimed at evaluating the effects of cognitive-motor dual-task training (CMDT) on sport-specific athletic performance and cognitive functions of semi-elite basketball players. Further, we investigated the CMDT effects on reactive brain processing by employing event-related potential (ERP) analysis. Design: A randomized controlled trial was conducted including 52 young semi-elite basketball players (28 females mean age 16.3 ± 1.1 years) who were randomly assigned into an experimental (Exp) group executing the CMDT and a control (Con) group performing standard motor training. Method: Athletes’ sport-specific performance was evaluated with dribbling tests before and after a five-week training. Cognitive performance was assessed by measuring speed and accuracy in a discrimination response task. Brain activity associated with sensory processing, selective attention, and decision-making was measured through the P1, N1, and P3 components. The CMDT consisted of simultaneous execution of dribbling exercises and cognitive tasks which were realized using interactive devices located around the athlete on the basket court. Data were submitted to a mixed analysis of variance. Results: Both groups showed some improvements from pre-to post-tests, but the Exp group improved basket-specific performance by 13% more than the Con group; in addition, the cognitive performance also improved more in the Exp group (25.8% in accuracy and 5.4% response speed). According to the EEG results, training did not affect sensory processing and attentional processing which were equally increased after both kinds of training; however, decision-making processes were specifically affected by the experimental training. Conclusions: This study confirmed the effectiveness of the proposed CMDT protocol on both sport-specific and cognitive performance of basketball players and showed that the neural basis of these benefits may be mediated by more intense decisional processing allowing faster connection between sensory encoding and response execution.     

Sex differences in sport spectator involvement

Among 107 male and 166 female college students, the present study examined sex differences in involvement with sports as spectators. A 14-item Likert-type scale was used to measure the subjects' emotional, cognitive, and behavioral involvement in sports as spectators. Confirming prior findings, male subjects exhibited higher involvement with sport spectating than did females. The current data also provide support for the unidimensionality, reliability, and validity of the Sport Spectator Involvement Scale.     

Parental involvement in competitive youth sport settings

ObjectivesBased on ecological systems theory [Bronfenbrenner, U. (2005). Making human beings human: Bioecological perspectives on human development. Thousand Oaks, CA: Sage], the purpose of this study was to examine parents’ involvement in competitive youth sport settings.DesignData were collected through two distinct phases of fieldwork. Phase 1 involved longitudinal data collection with four families. Phase 2 involved observations of youth soccer settings.MethodData were collected from four families via individual interviews and audio-diaries and were supplemented through 120 h of observation. Data were transcribed verbatim and analyzed using grounded theory methodology.ResultsParents’ verbal reactions to their children's sport performance behaviors were placed on a continuum moving from more supportive to more controlling comments. These comments were categorized as praise/encouragement, performance contingent feedback, instruction, striking a balance, negative comments, and derogatory comments. Parents experienced empathy in that they perceived sharing the emotions their children felt in sport, and these emotions appeared to change in relation to dynamic game and contextual circumstances. Parents also thought that they possessed knowledge and expertise of sport, which they perceived enabled them to make comments to their children.ConclusionA series of reciprocal and bi-directional relationships were central to parents’ involvement in competitive youth sport.     

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.     

Comparison of sport achievement orientation between wheelchair and able-bodied basketball athletes

Differences in sport achievement orientations between 31 recreational wheelchair and 76 able-bodied basketball athletes were tested. Athletes from the New England region completed the three subscales of the Sport Orientation Questionnaire (competitiveness, win orientation, and goal orientation). Wheelchair athletes responded higher on the Competitiveness and Goal Orientation subscales. In discriminative function analysis competitiveness scores were the only significant discriminator between the two groups.     

Anticipatory representation of visual basketball scenes by novice and expert players

This paper studies the anticipatory nature of perception in relation to subjects' expertise in basketball. The two experiments conducted showed that experts encode game situations by automatically building a representation of the next‐likely state of the observed scene. In Experiment 1, subjects had to quickly compare pairs of configurations presented in succession. The results indicated that expert subjects differentiated the second configuration from the first less accurately and more slowly when the second configuration was the next‐likely state of the first, than when it was a possible previous state. In Experiment 2, subjects had to study game configurations and then perform a recognition task. The results showed that experts more often falsely recognized new configurations when they were the next‐likely state of an already‐encoded configuration than when they represented a possible previous state. Based on these results, we discuss the nature of expert knowledge, the integration of anticipatory components in perceptual processes, and the impact of expert knowledge on visual‐scene encoding and memorization.     

Social class influence on female sport involvement

The purpose of this investigation was to analyze specific socioeconomic variables that may influence female participation in various sport types (team, individual, dual, and mixed). The first hypothesis predicted that sport type would be function of socioeconomic status. This hypothesis was verified, since team sport participants tended to come from a lower class background, while individual and dual sport participants had a higher social class status. The second hypothesis examined the relationship between reference group influence (family versus peer) and type of sport participation. No relationship was found between sport type and reference group influence. In addition, no relationship was found when socioeconomic status and type of reference group influence were examined together.     

The commitment of young soccer players

The main purpose of this study was to test the Sport Commitment Model in young soccer players. Participants' ( N = 437) age ranged from 14 to 16 years. Based on the sport commitment model proposed by Scanlan and colleagues, 6 scales and 28-items constitute the Sport Commitment Questionnaire (SCQ). Results of this study provide some support for the reliability and validity of the SCQ, using a sample of young soccer players. Reliability analysis provided acceptable internal consistency for four scales: Sport Commitment, Sport Enjoyment, Involvement Alternatives and Social Constraints. Sport Enjoyment (Beta= .56, p <.001) and Involvement Alternatives (Beta= -.40, p <.001) were the strongest sport commitment predictors. Further studies with a broader age range, different genders, and other sports or competitive levels are required to continue analyzing the sport commitment model.     

Personality profiles of young chess players

Although the game of chess has often featured in psychological research, we know very little about people who play chess, especially about children who take up chess as a hobby. This study presents the personality profiles as measured with the Big Five model (BFQ-C; Barbaranelli, Caprara, Rabasca, & Pastorelli, 2003) of 219 young children who play chess and 50 of their peers who do not. Children who score higher on Intellect/openness and Energy/extraversion are more likely to play chess while children who score higher on Agreeableness are less likely to be attracted to chess. Boys with higher scores on Agreeableness are less likely to take up chess than boys with lower scores. Considering that girls score higher on Agreeableness, this factor may provide one of the possible reasons why more boys are interested in chess. Although none of the Big Five factors were associated with self-reported skill level, a sub-sample of 25 elite players had significantly higher scores on Intellect/openness than their weaker chess playing peers.     

Comparison of mood states of college able-bodied and wheelchair basketball players.

The mood states of 26 college wheelchair basketball players were examined in relation to 11 varsity college basketball players and normative data from 340 college men. Multivariate analysis indicated that the wheelchair basketball players had significantly better mental health profiles than the two comparison groups.     

Ethnic identity and interethnic dating in Portuguese young adults

Forty undergraduate Rutgers-Newark students (21 women and 19 men) of Portuguese descent, aged 18 to 28, participated in a study on identity com-mitment and attitudes toward interethnic dating. High commitment to a Portuguese identity was associated with a collectivist orientation and with having a social network densely populated with Portuguese people. High personal concern with the ethnicity of one's dating partner was positively correlated with commitment to a Portuguese identity, and with having a social network densely populated with Portuguese people. High importance placed on parents' opinions about the ethnicity of dating and marriage partners was associated with a collectivist orientation. For women but not men, commitment was associated with high concern with one's partner's ethnicity. Results are discussed in terms of gender and the development of commitment to an ethnic identity.     

Observational analysis of the free throw shot made by grassroots basketball players

This article represents an approach to the free throw from the perspective of observational methodology. Faced with the obvious difficulty of transferring quantitative data resulting from the habitual biomechanical studies to everyday sports intervention, an easily accessible observational tool has been produced which, as a main contribution, allows the detection of T-patterns in free-throw shots. As the endorsement of the usefulness of the designed observational tool, an example is presented of the results obtained in a research design that studies a selection of grassroots basketball players (11-12 years).     

Perceptions of dual career development among elite level swimmers and basketball players

ObjectiveThe purpose of this study was to (1) examine swimmers' and basketball players' perceptions of their dual career development (2) explore these perceptions for possible differences between male and female participants as well as between swimmers and basketball players.Design and methodSemi-structured interviews with 12 retired Slovene elite level swimmers and basketball players (six males and six females) were used to discuss about transitions, demands and challenges which occurred throughout their dual career development. The interviews were transcribed verbatim and analysed using the qualitative analytic software program Nvivo 10.ResultsQualitative analysis of interviews revealed that athletes perceived their athletic career in strong and reciprocal connection to other domains in their lives, i.e. academic/vocational, psychological, psychosocial, financial level. Some of the transitions occurring in their dual career were experienced as particularly important (e.g., transition to university, finishing university study) and connected to several challenges occurring at different levels of development. Differences between male and female participants, swimmers and basketball players in this study were identified.ConclusionThe study revealed a usefulness of using a holistic perspective when investigating athletes' dual career development, and a reciprocal nature of transitions occurring at different levels of athletes' development.     

Social acceptability of sport for young women

Historically, according to Metheny, the acceptability of sport for women varies across several factors including ethnicity. 111 college age men and women were asked what sports they would allow and what sports they would forbid their daughter(s) to play. Results were consistent across ethnicity, sex, and religion. This younger generation would allow young women to participate in virtually all sports including contact sports.     

Intimacy,sport and young refugee men

This article is about research with a group of young refugee men from Sudan and their relationship to football (soccer) as they resettle in Australia. It provides evidence of the resilience, independence and autonomy that such young refugees possess and what these young men's intimate knowledge of these qualities can teach us. In other words, how can we as researchers learn from these young refugees about how they perform these qualities and how may we accommodate this during ethnographic research and in sports-based intervention programs aimed at empowering such young people? Further, the article explores the role of intimacy in this process by accounting for the role of affective connections on and off the sporting field. The argument is that intimacy can help those involved negotiate the power inequities present in sports-based intervention programs and in associated research.     

Physical activity and sport involvement in French high school students

The links between morphological, biological, sociological, psychological, and environmental characteristics, the practice of organized sports, and moderate to vigorous physical activities were examined by means of a questionnaire given to 48 high-school students aged between 16 and 19 years and their continuous heart-rate monitoring. Few correlations appear between these characteristics and moderate to vigorous physical activities. Only maximal oxygen uptake is linked to this type of activity in girls. Concerning sport involvement, correlations were more numerous for girls than boys. Physical and sports activities of girls were linked with maximal oxygen uptake, sport involvement of father, support, and encouragements of practice, perception of own activity, and private environment. Among boys, physical and sport activities were only linked with sport involvement of friends and perception of own activity. Unlike boys, physical and sport activities among girls seemed more strongly linked to sociological characteristics than other ones.     

Number of players who gain ball possession as a function of basketball mass among 9-11-year-old male players

This study analyzed whether a ball with a higher (540-g) or lower (440-g) mass than the regulation ball (485-g) resulted in a larger number of participants gaining ball possession during games. Prior studies have indicated that ball handling is facilitated by decreasing the mass of the ball. It was assumed that a greater number of children gaining possession of the ball indicated greater ease of use and more control. Thus, the hypothesis was that the number of participants who gained ball possession would increase when using a ball of lower mass. The participants were 54 boys from six youth basketball teams. Participants played four games with each one of the three different balls and the number of possessions was calculated using videos of each game. The hypothesis was only partially supported: the number of participants who gained possession with the regular ball was similar to that with the 440-g ball and with the 540-g ball, but a greater number of participants gained possession with the 440-g ball in comparison to the 540-g ball. This result suggests balls that differ by more than 65 g may affect actual game outcomes.     

Relationship between biological markers and psychological states in elite basketball players across a competitive season

ObjectiveThe main objective of the study was to examine the relation of different biological markers to a variety of pleasant and unpleasant psychobiosocial (PBS) states in response to precompetitive stress in sport.DesignA longitudinal design was adopted to assess biological markers and PBS states before several games.MethodA whole team of high-level professional basketball players (9 men, aged from 23 to 37 years) took part in the study. The biological measures included the salivary concentration of testosterone, cortisol, aamylase, and chromogranin A. The psychological measures involved emotional, cognitive, motivational, bodily, kinesthetic, performance, and communicative components of PBS states assessed according to the dimensions of their intensity, frequency, and direction (i.e., perceived effect on performance). Assessment was conducted within 1 h prior to competition on an approximately weekly basis across the whole championship for a total of 12 games played at the team's home.ResultsA series of canonical correlation analyses showed that an increase in the salivary concentration of biological variables was associated with enhanced intensity and frequency scores of pleasant PBS states, as well as enhanced directional values (i.e., perception of facilitative effects) of a range of both pleasant and unpleasant PBS states.ConclusionFindings suggest that elevation of testosterone, cortisol, α-amylase, and chromogranin A in basketball players prior to competition can have a perceived functional effect with respect to the upcoming performance.
