Validity and generalizability of social dance performance ratings.

The purpose of three related studies was to develop a social dance instrument that had logical validity and generalizable performance ratings. Three social dance experts critiqued the instrument and concluded the items described the characteristics of good social dance performance. Twelve couples from a social dance class were videotaped for 5 min while performing the fox trot. Their performances were evaluated by a different set of coders in each of the three generalizability (G-) studies conducted (Subjects x Coders x Days ANOVA design). Dance performances were held constant across coding occasions so the day facet represents degree of consistency in coding, not stability of subjects' performances. Decision (D-) studies were also conducted for various measurement conditions. Results of the G-studies indicated that coders with several years of experience teaching and evaluating dance had less systematic coder bias and less systematic coder bias for a subset of dancers than coders who had little or no experience evaluating movement of any form. The performance ratings given by novice coders could be generalized for any randomly selected coder evaluating on any given day (G = .79). It was concluded the social dance test was valid and coders could be trained to obtain generalizable performance ratings.     

A Cognitive Behavioral Intervention for Improving Basketball Performance

Abstract

The purpose of the present experiment was to replicate and extend previous developmental modeling research by examining the qualitative as well as quantitative aspects of motor performance. Eighty females of two age groups (5–0 to 6–6 and 7–6 to 9–0 years) were randomly assigned to conditions within a 2 × 2 × 2 (Age x Model Type x Rehearsal) factorial design. Children received either verbal instructions only (no model) or a visual demonstration with experimenter-given verbal cues (verbal model) of a five-part dance skill sequence. Children were either prompted to verbally rehearse before skill execution or merely asked to reproduce the sequence without prompting. Both quantitative (order) and qualitative (form) performances were assessed. Results revealed a significant age main effect for both order and form performance, with older children performing better than younger children. A model type main effect was also found for both order and form performance. The verbal model condition produced better qualitative performance, whereas the no model condition resulted in better quantitative scores. These results are discussed in terms of differential coding strategies that may influence task components in modeling.     

Football: A Sociology of the Global Game By Richard Giulianotti. Published 1999 by Polity Press, 65 Bridge Street,Cambridge, CB2 1UR,UK. (256 pp., $29.95)

Martial-arts practice is not quite anything else: it is like sport, but is not sport; it constantly refers to and as it were cohabits with violence, but is not violent; it is dance-like but not dance. It shares a common athleticism with sports and dance, yet stands apart from both, especially through its paradoxical commitment to the external value of being an instrument of violence. My discussion seeks to illuminate martial arts practice by systematic contrast to games of sport and works of performance art, especially dance.     

The psychology of elite cycling: a systematic review

This systematic review sought to synthesise what is currently known about the psychology of elite cycling. Nine electronic databases were searched in March 2017 for studies reporting an empirical test of any psychological construct in an elite cycling sample. Fourteen studies (total n = 427) met inclusion criteria. Eight studies were coded as having high risk of bias. Themes extracted included mood, anxiety, self-confidence, pain, and cognitive function. Few studies had similar objectives meaning that in many instances findings could not be synthesised in a meaningful way. Nevertheless, there was some cross-study evidence that elite cyclists have more positive mood states (relative to normative scores), pre-race anxiety impairs performance (among male cyclists), and associative strategies are perceived as helpful for pain management. Among single studies coded as having low risk of bias, evidence suggests that implicit beliefs affect decision making performance, elite cyclists are less susceptible to mental fatigue (than non-elite cyclists), and better leadership skills relates to greater social labouring. Limitations include non-standardisation of measures, lack of follow-up data, small sample sizes, and overall poor research quality. The findings of this systematic review might be used to inform research and theory development on the psychology of elite endurance cycling.     

A Comparison of Video and Text-Based Questionnaire Methods for Testing Older Adults

Abstract

The purpose of this study was to initiate systematic research on dance as a creative and expressive art form. Although the process of expression through movement has concerned dancers and dance teachers for some time, there have been few attempts at a systematic analysis of either the process or the product of dance expression. Dance has generally been considered immeasurable because of its peculiarities as an art form.

While there is little apparent value in quantitative measurement of dance, qualitative measurement appears to have considerable value. It can sharpen the focus on principles of dance composition, contribute toward increased teaching effectiveness, enlarge dance's expressive range, and increase its ability to communicate.

Specifically, this study attempted to determine how effectively modern dance communicates by using a systematic analysis of individual dance compositions. Samples of dance studies with specific intentions were choreographed and filmed. The dances were then viewed and evaluated by a selected and trained jury on (a) their ability to communicate emotional and physical qualities, (b) the type and structure of their composition, and (c) their choreographic and artistic effectiveness.

Results of this study showed that least agreement was reached by the jurors in rating the dances according to structural strength and in identifying their composition type. Realistic vehicles of expression were more easily recognized than were abstract ones. There was substantial agreement on the emotion communicated by each composition. Presence of all the traditional dance elements appears unnecessary for effective communication.     

A System for the Behavioral Assessment of Athletic Coaches

Abstract

A behavioral assessment system for coding and analyzing the behaviors of athletic coaches in naturalistic settings is described. The Coaching Behavior Assessment System (CBAS) consists of 12 behavioral categories derived from content analyses of coaching behaviors during practices and games. The manner in which coders are trained and the CBAS used in field settings is described, and the results of several reliability studies are reported. These studies indicate that high scorer accuracy and interrater reliability can be attained. The potential use of the CBAS to extend the study of interpersonal behavior into the realm of sport psychology is also discussed.     

Development of an Objective Measure of Rhythmic Motor Response

Abstract

This study was undertaken to develop a test that would objectively measure the rhythmic element in dance, and one that could be used by teachers of dance. The resulting Test of Rhythmic Motor Response was administered to 92 college women enrolled in dance classes. Test reliability coefficients ranged from .90 to .91; validity coefficients with teachers' ratings, .49 to .51. An investigation of the relationship between this test and the rhythm imagery section of the Gordon Measures of Musical Perception yielded correlation coefficients ranging from .52 to .69. These findings are all statistically significant at the .01 level. The Test of Rhythmic Motor Response appears to have a substantial relationship with the rhythmic element in dance.     

Do people with low back pain walk differently? A systematic review and meta-analysis

BackgroundThe biomechanics of the trunk and lower limbs during walking and running gait are frequently assessed in individuals with low back pain (LBP). Despite substantial research, it is still unclear whether consistent and generalizable changes in walking or running gait occur in association with LBP. The purpose of this systematic review was to identify whether there are differences in biomechanics during walking and running gait in individuals with acute and persistent LBP compared with back-healthy controls.MethodsA search was conducted in PubMed, CINAHL, SPORTDiscus, and PsycINFO in June 2019 and was repeated in December 2020. Studies were included if they reported biomechanical characteristics of individuals with and without LBP during steady-state or perturbed walking and running. Biomechanical data included spatiotemporal, kinematic, kinetic, and electromyography variables. The reporting quality and potential for bias of each study was assessed. Data were pooled where possible to compare the standardized mean differences (SMD) between back pain and back-healthy control groups.ResultsNinety-seven studies were included and reviewed. Two studies investigated acute pain and the rest investigated persistent pain. Nine studies investigated running gait. Of the studies, 20% had high reporting quality/low risk of bias. In comparison with back-healthy controls, individuals with persistent LBP walked slower (SMD = –0.59, 95% confidence interval (95%CI): –0.77 to –0.42)) and with shorter stride length (SMD = –0.38, 95%CI: –0.60 to –0.16). There were no differences in the amplitude of motion in the thoracic or lumbar spine, pelvis, or hips in individuals with LBP. During walking, coordination of motion between the thorax and the lumbar spine/pelvis was significantly more in-phase in the persistent LBP groups (SMD = –0.60, 95%CI: –0.90 to –0.30), and individuals with persistent LBP exhibited greater amplitude of activation in the paraspinal muscles (SMD = 0.52, 95%CI: 0.23–0.80). There were no consistent differences in running biomechanics between groups.ConclusionThere is moderate-to-strong evidence that individuals with persistent LBP demonstrate differences in walking gait compared to back-healthy controls.     

Motor performance and bodyweight of children and adolescents in Saarland – Status quo

Abstract

The motor performance of children and adolescents has been a subject of controversial discussion. As part of a pilot project, 839 schoolchildren from 14 different schools in Saarland were studied and their height, weight and sport motor performance were measured using the German motor performance test DMT 6-18. The results show a slight increase in the number of overweight children compared to reference samples. However, these discrepancies are minor and cannot be judged to be practically relevant because of the weakness of the effects. The average motor test performances of the Saarland schoolchildren were above the average performance of the reference samples in almost all individual performances. There are also hardly any weaker performances in comparison to older studies. The current results for motor performance of Saarland children and adolescents do not, therefore, give any great reason for concern. Further evaluation steps will be needed to clarify the influences that might be associated with adverse characteristics for motor performance (socio-economic status, living situation, leisure behaviour, school performance, etc.).

Expectancy effects in tennis: The impact of opponents' pre-match non-verbal behaviour on male tennis players

Abstract

In this study, we examined the impact of a male opponent's pre-match body language and clothing (general vs. sports-specific) on how his performances were judged by an observer. Forty male tennis players viewed videos of a male target tennis player warming up and then observed playing footage of the target. Each participant viewed the target player warming up displaying one of four combinations of body language and clothing (positive body language/tennis-specific clothing; positive body language/general sportswear; negative body language/tennis-specific clothing; negative body language/general sportswear). Participants rated the performance of the tennis player and gave their perceptions of the likely outcome of a tennis match with the target player. Analyses of variance indicated that clothing and body language had an interactive effect on both outcome expectations and ratings of performance. The findings support the contention that the initial impressions athletes form of their opponents can influence the way in which they judge the performances of opponents and their perceived likelihood of success against the same opponents.     

Participation Profiles and Socialisation into Dance Among Non‐Professional Dancers

Abstract

The study was designed to determine how individuals become socialised into folk, competitive ballroom, ballet and modern dance through an investigation of background variables, the influence of significant others and the participation profiles of dancers, and the identification of those socialization and involvement variables that best discriminate among different groups of dancers.

The subjects were 308 adolescent and adult dancers of at least 16 years of age who had pursued their main dance form for a minimum of three years. The data were collected by questionnaire, supplemented with some additional data gathered through personal interviews. Differences between the four dance groups were analysed using t‐test, Chi Square analyses, analyses of variance, Scheffe's multiple‐range test and discriminant analysis.

Most subjects were from the middle or upper socio‐economic classes. Most art dancers were women while social dancers displayed a more even distribution of sexes. Ballet dancers were youngest and ballroom dancers oldest when they started dancing. Mother's influence was significant among those who had started dancing at a young age while a friend of the same sex was influential among all respondents regardless of the age at which they had taken up dancing. Among men the influence of a friend of the opposite sex was also significant. The involvement of other family members in dance correlated most strongly with folk dancing, least strongly with modern dance. The dance teacher or coach was perceived as the most encouraging person in every dance form.

The most wide‐ranging past and present dance activities were found among modern dancers. The variables which best discriminated between dance forms were starting age, the variety of present dance activities and the intensity of practising one's main dance form. Such differences in socialisation into different dance forms should be taken into account when developing dance and dance teacher education curricula, teaching dance and planning recreational dance activities.

The development of a reliable amateur boxing performance analysis template

Abstract

The aim of this study was to devise a valid performance analysis system for the assessment of the movement characteristics associated with competitive amateur boxing and assess its reliability using analysts of varying experience of the sport and performance analysis. Key performance indicators to characterise the demands of an amateur contest (offensive, defensive and feinting) were developed and notated using a computerised notational analysis system. Data were subjected to intra- and inter-observer reliability assessment using median sign tests and calculating the proportion of agreement within predetermined limits of error. For all performance indicators, intra-observer reliability revealed non-significant differences between observations (P > 0.05) and high agreement was established (80–100%) regardless of whether exact or the reference value of ±1 was applied. Inter-observer reliability was less impressive for both analysts (amateur boxer and experienced analyst), with the proportion of agreement ranging from 33–100%. Nonetheless, there was no systematic bias between observations for any indicator (P > 0.05), and the proportion of agreement within the reference range (±1) was 100%. A reliable performance analysis template has been developed for the assessment of amateur boxing performance and is available for use by researchers, coaches and athletes to classify and quantify the movement characteristics of amateur boxing.     

From Exclusion to Inclusion: Changes in Women’s Roles in Folk Sports and Indigenous Physical Culture in China

Abstract

The physical culture of Chinese folk sports is embedded in religions and rituals that have been predominantly ruled by men. However, this situation has been changing as the forms and meanings of folk sports transform in modern China. Based on the literature and interviews, in this research, the Funeral Dance of the Tujia ethnic group was considered as a case to explore how gender roles in Tujia indigenous physical activity changed during the modernizing process. Given the transformation of Funeral Dance from an indigenous funeral ritual to a national fitness programme and public and commercial performances, Tujia women have gained social access, legal status, national identity, and value, allowing them to participate in the dance. Policy interventions, capitalist drive, and social progress constituted an integral force that has systematically challenged the engendered nature of Chinese folk sports. Nevertheless, in Tujia’s conceptual framework, there is an invisible curtain between the stage and backstage of Funeral Dance performances. In the ‘front’, the participation of women is fully encouraged; however, ‘backstage’, the gender taboo remains as a so-called sporting tradition. The inclusion of both genders in folk sports is an unavoidable tendency in China, though the gendered boundaries continue to impact on women’s participation.     

Injury rates and characteristics in recreational,elite student and professional dancers: A systematic review

The purpose of this study was to systematically review the literature and synthesise the evidence on injury rates and characteristics in recreational, elite student, and professional dancers. Five online databases were searched from inception to January 2018 and screened by two independent reviewers. Primary research studies were eligible for inclusion if they reported injury rates in recreational, elite student, and/or professional dancers of any genre and measured individual dance exposure at the hour, event, or day level. Sixteen studies were included, with only three studies incorporating recreational dancers. Reported injury incidence rates were less than 5 injuries per 1,000 dance hours, however substantially different definitions and methods for measuring injury and dance exposure were used. Based on the current evidence there is not an identifiable difference in injury rate or characteristics between recreational, elite student, and professional dancers. However, there remains a lack of high quality comprehensive data available across levels and genres of dance participation, and greater focus on consistency and completeness of reporting in dance injury research is still required.     

Causal Attributions following Success and Failure at an Achievement Motor Task

Abstract

Past research has shown that success is predominantly attributed to internal factors and failure attributed to external factors. The purpose of the present experiment was to determine whether this attributional pattern was also found when subjects were performing a motor task. The degree of ego involvement in the task (evaluation) and the effect of prior practice (novelty) were also investigated in order to determine the extent to which these variables affect subjects' self-attributions. Thus, the effects of ego involvement and past experience following success and failure on causal attributions were investigated in a 2 × 2 × 2 (evaluation × novelty × outcome) factorial design with 80 college undergraduates. The task was a motor maze. Consistent with past research, subjects showed a relative tendency toward internal attributions over external attributions and a tendency toward stable attributions over unstable attributions. Moreover, success increased the relative bias toward internal attributions. However, evaluation apprehension and experience with the motor task did not interact with outcome to affect internal and external attributions.

广场舞联盟：草根社会组织的生存与发展

广场舞是近年来在全国各地广泛开展的一种群众性文体活动,影响已经波及到国外。在上海数不胜数的广场舞团队中大多是自发的团队,遍布市内各社区和公共场地。为了用组织化方式实现基层治理,上海市嘉定区文化广播电视管理局委托一个正规注册的“民非”机构,以大赛为载体,成立了广场舞联盟。从“嘉定区广场舞联盟”到“上海市民广场舞联盟”,这一草根社会组织发挥了积极的作用,也缓解了一些社会矛盾和冲突,但缺乏登记注册的“合法身份”,却成为其更好地生存和发展的体制障碍。这也正反映了当下中国社会重新组织化的趋势和特点。
