Abstract Russell, Benton and Kingsley (2010) recently suggested a new association football test comprising three different tasks for the evaluation of players' passing, dribbling and shooting skills. Their stated intention was to enhance ‘ecological validity’ of current association football skills tests allowing generalisation of results from the new protocols to performance constraints that were ‘representative’ of experiences during competitive game situations. However, in this comment we raise some concerns with their use of the term ‘ecological validity’ to allude to aspects of ‘representative task design’. We propose that in their paper the authors confused understanding of environmental properties, performance achievement and generalisability of the test and its outcomes. Here, we argue that the tests designed by Russell and colleagues did not include critical sources of environmental information, such as the active role of opponents, which players typically use to organise their actions during performance. Static tasks which are not representative of the competitive performance environment may lead to different emerging patterns of movement organisation and performance outcomes, failing to effectively evaluate skills performance in sport. 相似文献

Abstract The purpose of the present research was to test the applicability of the Dualistic Model of Passion (Vallerand et al., 2003) to being a sport (football) fan. Three studies provided support for this dualistic conceptualization of passion. Study 1 showed that harmonious passion was positively associated with adaptive behaviours (e.g. celebrate the team's victory), whereas obsessive passion was positively associated with maladaptive behaviours (e.g. risking losing one's job to go to a game). Study 2 used a short Passion Scale and showed that harmonious passion was positively related to the positive affective life of fans during the 2006 FIFA World Cup, psychological health (self-esteem and life satisfaction), and public displays of adaptive behaviours (e.g. celebrate the team's victory into the streets), whereas obsessive passion was predictive of maladaptive affective life (e.g. hating opposing teams' fans) and behaviours (e.g. mocking opposing teams' fans). Finally, Study 3 examined the role of obsessive passion as a predictor of partner's conflict that in turn undermined partner's relationship satisfaction. Overall, the present results provided support for the Dualistic Model of Passion. The conceptual and applied implications of the findings are discussed. 相似文献

Abstract We previously proposed two predictive equations of visceral fat area applicable in a field setting (Demura & Sato, 2007a, 2007b). One uses the fat mass of the trunk measured by bioelectrical impedance as the main predictor (equation 1) and the other uses internal fat mass estimated from several anthropometric variables (equation 2). In this study, we examined the inter- and intra-individual accuracy of estimated values using these equations after 8 weeks of exercise training. Participants were 42 Japanese adults aged 42.7 ± 10.3 years (22 males, 20 females). Visceral fat area, body composition, and blood biochemistry were measured at baseline and after 8 weeks. There were no significant differences in reference visceral fat area measured by computed tomography and visceral fat area predicted by the equations either at baseline or after 8 weeks, and the values were highly consistent (equation 1: baseline R 2 = 0.829, after R 2 = 0.860; equation 2: baseline R 2 = 0.832; after R 2 = 0.850). No significant relationship was observed between the reference and change in visceral fat area for equation 1 (males: r = 0.272, P > 0.05; females: r = 0.428, P > 0.05), but there was a significant relationship for females with equation 2 (males: r = 0.279, P > 0.05; females: r = 0.474, P <0.05). Our findings indicate that these equations have high inter-individual consistency but low intra-individual consistency with the reference and are of limited use for the longitudinal evaluation of visceral fat area. 相似文献

Abstract Swain (1997) employed the mathematical model of Di Prampero et al. (1979) to predict that, for cycling time-trials, the optimal pacing strategy is to vary power in parallel with the changes experienced in gradient and wind speed. We used a more up-to-date mathematical model with validated coefficients (Martin et al., 1998) to quantify the time savings that would result from such optimization of pacing strategy. A hypothetical cyclist (mass = 70 kg) and bicycle (mass = 10 kg) were studied under varying hypothetical wind velocities (?10 to 10 m · s?1), gradients (?10 to 10%), and pacing strategies. Mean rider power outputs of 164, 289, and 394 W were chosen to mirror baseline performances studied previously. The three race scenarios were: (i) a 10-km time-trial with alternating 1-km sections of 10% and ?10% gradient; (ii) a 40-km time-trial with alternating 5-km sections of 4.4 and ?4.4 m · s?1 wind (Swain, 1997); and (iii) the 40-km time-trial delimited by Jeukendrup and Martin (2001). Varying a mean power of 289 W by ± 10% during Swain's (1997) hilly and windy courses resulted in time savings of 126 and 51 s, respectively. Time savings for most race scenarios were greater than those suggested by Swain (1997). For a mean power of 289 W over the “standard” 40-km time-trial, a time saving of 26 s was observed with a power variability of 10%. The largest time savings were found for the hypothetical riders with the lowest mean power output who could vary power to the greatest extent. Our findings confirm that time savings are possible in cycling time-trials if the rider varies power in parallel with hill gradient and wind direction. With a more recent mathematical model, we found slightly greater time savings than those reported by Swain (1997). These time savings compared favourably with the predicted benefits of interventions such as altitude training or ingestion of carbohydrate-electrolyte drinks. Nevertheless, the extent to which such power output variations can be tolerated by a cyclist during a time-trial is still unclear. 相似文献

Abstract Coaching has been recognised as a demanding occupation, associated with a range of stressors. The extent to which coaches perceive stress is likely to be influenced by various personal and situational factors. The purpose of this study was to identify coaches' levels of perceived stress and examine the personal and situational factors that may influence coaches' perceptions of stress. In total, 502 coaches working with university, college, Canada Games, and/or nationally identified athletes completed this study. Coaches completed an online survey, which included questions regarding demographics, work/job-related considerations, and aspects relating to their contract. Coaches also completed the Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983). Overall coaches indicated slightly below average levels of perceived stress (M = 15.13 out of 40) compared with norm-values (Cohen & Janicki-Deverts, 2012). Demographic factors, job-related characteristics, and certain aspects of their contract were associated with coaches' perceptions of stress. In particular, unclear expectations, long-working hours (>40), lack of agreed evaluation criteria, higher salaries, and a lack of social support were related to higher perceptions of stress. As such, the findings of the current study indicate that a reduction in perceived stress is likely to be achieved through a multifaceted approach that addresses multiple factors associated with coaching. 相似文献

Abstract The aim of this study was to examine stressors, coping, and coping effectiveness as a function of gender, type of sport, and skill. The sample consisted of 749 undergraduate athletes (455 males, 294 females) aged 18 – 38 years (mean = 19.8 years). Skill was classified as international/national, county, university, and club standard. Participants completed a stressor and coping concept map (Novak & Gowin, 1984). The results revealed gender, type of sport, and skill differences in relation to stressor frequencies, coping strategy deployment, and coping effectiveness. In contrast to previous research, females used a variety of problem-focused (e.g. planning, communication, technique-orientated coping) strategies more frequently than males. Team sport athletes reported a variety of sport-specific stressors relating to the demands of playing in a team environment. The group of national/international athletes reported using more planning, blocking, and visualization, and also reported that their coping was more effective than that of less-skilled athletes. 相似文献

Background: Pleasure is often a key feature of school physical education (PE) and, indeed, a lot of students find pleasure in and through PE while others do not. However, pleasure is rarely considered to be of educational value in the subject [Pringle, R. (2010). “Finding Pleasure in Physical Education: A Critical Examination of the Educative Value of Positive Movement Affects.” Quest 62: 119–134]. Further, since pleasure is linked to power [Foucault, M. (1980). Power/Knowledge: Selected Interviews and Other Writings, 1972–1977. New York: Pantheon; Gerdin, G., and R. Pringle. (2015). “The Politics of Pleasure: An Ethnographic Examination Exploring the Dominance of the Multi-Activity Sport-Based Physical Education Model.” Sport, Education and Society. doi:10.1080/13573322.2015.1019448] it is in fact not entirely straightforward to legitimise the educational value of PE in relation to pleasure.
Purpose: In this paper, we explore how a group of boys derive pleasures from their involvement in PE, but also how these power-induced pleasures are integral to gender normalisation processes. The findings presented are particularly discussed in terms of inclusive/exclusive pedagogical practices related to gender, bodies and pleasures.
Research setting and participants: The research setting was a single-sex, boys’ secondary school in Auckland, New Zealand. Participants in this study were 60 Year 10 (age 14–15) students from two PE classes.
Data collection and analysis: Using a visual ethnographic approach [Pink, S. (2007). Doing Visual Ethnography. London: Sage] involving observations and video recordings of boys participating in PE, the boys’ representations and interpretations of the visual data were explored during both focus groups and individual interviews. The data were analysed using (a visually oriented) discourse analysis [Foucault, M. (1998). “Foucault.” In Michel Foucault. Aesthetics, Method and Epistemology, edited by J. D. Faubion, 459–463. New York: The New Press; Rose, G. (2007). Visual Methodologies: An Introduction to the Interpretation of Visual Materials. London: Sage].
Findings: By elucidating the discursive practices of PE in this setting and employing (Butler, J. (1993). Bodies that Matter: On the Discursive Limits of ‘Sex’. New York: Routledge] concept of ‘materialisation’, we suggest that boy’s bodies materialise as productive and pleasurable or displeasurable bodies through submitting/subjecting to certain bodily regimes, developing embodied mastery when it comes to certain sports, and displaying bodies in particular ways. The analysis indicate that the discursive practices of PE contribute to boys’ bodies materialising as pleasurable or displeasurable and the (re)production of gender in the subject as shaped by discourse and the productive effect of power.
Discussion and conclusions: In line with [Gard, M. (2008). “When a Boy’s Gotta Dance: New Masculinities, Old Pleasures.” Sport, Education and Society 13 (2): 181–193], we conclude that the focus on certain discursively constructed bodily practices at the same time continues to restrict the production of a diversity of bodily movement pleasures. Hence, traditional gender patterns are reproduced through a selection of particular sports/physical activities that all the students are expected to participate in. We propose that the ongoing constitution of privileged forms of masculinity, masculine bodies and masculine pleasures as related to fitness, health and sport and (certain) boys’ subsequent exercise of power in PE needs further critical examination. 相似文献

Abstract We analyse the evolution of the slope (critical speed) and the y-intercept (anaerobic distance capacity) of the linear distance–time relationship over a century of Olympic running performances. The distance–time relationship of each Olympic Games (1920–2004) was plotted using the performances in the 800-, 1500- and 5000-m track events. Values for critical speed and anaerobic distance capacity were determined by linear modelling. Mean performances for the 800, 1500 and 5000 m were 104.9 ± 1.5 s (1.4%), 217.2 ± 2.8 s (1.3%) and 808.9 ± 18.4 s (2.3%), respectively. Critical speed improved during the first three-quarters of the twentieth century to reach a plateau in 1984. This is in accordance with the literature (Peronnet & Thibault, 1989) and suggests that “human aerobic endurance” has improved within the century (+13.4%) and tends to stabilize. Anaerobic distance capacity was highly variable over the century (coefficient of variation = 9.4%) and did not show a linear improvement over the years as has previously been suggested (Peronnet & Thibault, 1989). This could be due to an artefact in the application of the two-parameter model to only three Olympic performances. A limitation to the use of this linear mathematical model to fit physiological data may have been demonstrated. 相似文献

Abstract Baldo et al. (2002) and Helsen et al. (2006) considered the flash-lag effect to explain errors made by assistant referees when judging offside in association football. The main aims of the present study were as follows: (1) to determine whether the flash-lag effect emerges in offside situations on the field of play or off the field when presented as computer animations or as video footage of real-life matches; (2) to examine offside decision-making errors in two standards of assistant referee – international FIFA and Belgian national referees. The results support the flash-lag hypothesis in several ways. First, both the FIFA and Belgian assistant referees were more likely to make errors by raising their flag when they had to assess offside situations on the field of play and when presented as three-a-side computer animations. Second, more flag errors were made when the defender moved in the opposite direction to that of the attacker. Third, the strategy of raising the flag in case of doubt was not observed when an interpretation of the offside law had to be made about the involvement of play of an attacker. Future research is needed to examine the extent to which on- and off-the-field training sessions can be used as training tools to improve offside decision-making. 相似文献

Background: Student-Centered Inquiry as Curriculum (SCIC) is an activist approach [Oliver, K. L., and H. A. Oesterreich. 2013. Student-Centered Inquiry as Curriculum as a Model for Field-Based Teacher Education. Journal of Curriculum Studies 45 (3): 394–417. doi:10.1080/00220272.2012.719550] inspired by years of research with youth. It was designed as a means of listening and responding to youth in order to better facilitate students’ interest, motivation, and learning in physical education settings. While we have a strong and growing body of activist research with youth in physical education, SCIC as a specific approach to working with youth is in its infancy; thus, there is a need to further explore the challenges teachers/researchers face learning to use this approach to teaching.
Purpose: This study explores how educators, in different contexts, learn to use an activist approach called SCIC, in order to better facilitate students’ interest, motivation, and learning in physical education and physical activity settings.
Research setting and participants: Participants included a university professor, a college instructor, a postdoctoral student, a doctoral student, and a pre-service teacher. Data were collected between January and May 2016.
Data collection and analysis: Data collection included weekly field notes and debriefings following observations, teacher artifacts, weekly collaborative group meetings, and two individual interviews per teaching participant.
Discussion and conclusions: The main challenge that emerged was learning how to move from a theoretical understanding of student-centered pedagogy to the practice of student-centered pedagogy. Specifically, the amount of time that was necessary to build a foundation that allowed for student and teacher understanding, respect, and comfort, negotiating teacher and student assumptions that were embedded in the status quo of physical education (PE), and the struggle to gather and use meaningful data to guide pedagogical decisions. We negotiated these challenges through our professional learning community whereby we worked to all be able to see and name what was happening in our individual classes and collectively planned what was needed to move forward through these challenges. 相似文献

The aim of this research was to develop an exercise-related goal orientation measure in an attempt to further researchers' and practitioners' current understanding of individuals' motivation to exercise for health and recreational purposes. The Goal Orientation in Exercise Measure (GOEM) was developed to assess individuals' proneness to endorse task or ego goals. Participants included 372 males and females from 16 recreational physical activity clubs in Southeast England. Confirmatory factor analysis (CFA) supported the two-factor model and demonstrated invariance between sexes. Internal consistency for task and ego subscales was .78 and .88, respectively, while correlations between the goal orientations and behavioral regulations (Markland & Tobin, 2004) served to provide initial evidence for the construct validity of the measure. The development of the GOEM may allow for a broader understanding of the motivational processes implicated in exercise-related domains. 相似文献

Abstract The aim of this study was to compare maximal accumulated oxygen deficit (hereafter O2 deficit) estimated from the methods of Whipp et al. (1986), Medbo et al. (1988), and Hill et al. (1998) to determine whether they agree sufficiently to be used interchangeably. Nineteen moderately to highly trained endurance runners first performed an incremental test to exhaustion for the determination of maximal oxygen uptake ([Vdot]O2max) and peak treadmill speed, followed by six randomly ordered constant-speed tests at 95, 100, 105, 110, 110, and 120% of peak treadmill speed. All tests were separated by at least 72 h and were performed within 4 weeks. The method of Whipp produced an O2 deficit estimate that was lower than that derived from the method of Hill or Medbo (bias ± 95% limits of agreement: ?29.6 ± 36.6 and ?26.1 ± 32.8 ml · kg?1, respectively; P < 0.001). The O2 deficit did not differ between the methods of Hill and Medbo (bias ± 95% limits of agreement: 3.5 ± 41.6 ml · kg?1; n.s.). However, poor correlations (0.21 < r < 0.33; n.s.) together with wide limits of agreement between O2 deficit estimates (70 – 80% of the mean response) clearly question using these methods interchangeably. 相似文献

Abstract In the present study, a measure to assess the motivational qualities of music in exercise was redesigned, extending previous research efforts (Karageorghis et al., 1999). The original measure, the Brunel Music Rating Inventory (BMRI), had shown limitations in its factor structure and its applicability to non-experts in music selection. Redesign of the BMRI used in-depth interviews with eight participants (mean age 31.9 years, s = 8.9 years) to establish the initial item pool, which was examined using a series of confirmatory factor analyses. A single-factor model provided a good fit across three musical selections with different motivational qualities (comparative fit index, CFI: 0.95–0.98; standardized root mean residual, SRMR: 0.03–0.05). The single-factor model also demonstrated acceptable fit across two independent samples and both sexes using one piece of music (CFI: 0.86–1.00; SRMR: 0.04–0.07). The BMRI was designed for experts in selecting music for exercise (e.g. dance aerobic instructors), whereas the BMRI-2 can be used both by exercise instructors and participants. The psychometric properties of the BMRI-2 are stronger than those of the BMRI and it is easier to use. The BMRI-2 provides a valid and internally consistent tool by which music can be selected to accompany a bout of exercise or a training session. Furthermore, the BMRI-2 enables researchers to standardize music in experimental protocols involving exercise-related tasks. 相似文献

AbstractApplied research suggests that athletes and coaches need to be challenged in knowing when and how much a movement should be consciously attended to. This is exacerbated when the skill is in transition between two more stable states, such as when an already well-learnt skill is being refined. Using existing theory and research, this paper highlights the potential application of movement variability as a tool to inform a coach's decision-making process when implementing a systematic approach to technical refinement. Of particular interest is the structure of co-variability between mechanical degrees-of-freedom (e.g., joints) within the movement system's entirety when undergoing a skill transition. Exemplar data from golf are presented, demonstrating the link between movement variability and mental effort as an important feature of automaticity, and thus intervention design throughout the different stages of refinement. Movement variability was shown to reduce when mental effort directed towards an individual aspect of the skill was high (target variable). The opposite pattern was apparent for variables unrelated to the technical refinement. Therefore, two related indicators, movement variability and mental effort, are offered as a basis through which the evaluation of automaticity during technical refinements may be made. 相似文献

Abstract In this study, I examined the main and interactive effects of attribution dimensions on efficacy expectations in sport. A sample of 162 athletes (102 males, 60 females) aged 20.9 years (s = 3.4) from various sports were recruited. The participants, who were of club to international standard, completed the Causal Dimension Scale II (McAuley et al., 1992) in relation to their most recent performance. They then completed a 7-item measure of efficacy expectations in relation to their upcoming performance. The key predictors of efficacy expectations were stability and personal control, but their function differed after more or less successful performances. After more successful performances, attributions to stability and personal control were associated with main effects upon efficacy expectations, in a positive direction; after less successful performances, attributions to stability and personal control were associated with an interactive effect upon efficacy expectations. The form of this effect was such that the participants were more likely to have high efficacy expectations only when they viewed the cause of their performances as both personally controllable and stable. 相似文献

The Trichotomous Achievement Goal Scale was developed by Agbuga and Xiang (2008) by including selected items from the scales of Duda and Nicholls (1992), Elliot (1999), and Elliot and Church (1997) and adapting them into Turkish. The scale consists of 18 items, and students rated each item on a 7-point Likert scale. To ascertain the validity and reliability of the Trichotomous Achievement Goal Scale, it was administered to 845 female and 861 male Turkish high school students attending three public schools in the 2008–2009 spring semester. Exploratory and confirmatory factor analyses were conducted, and Cronbach's alpha and Fornell and Larcker's (1981) criteria were tested on the items that measured the students' achievements, screening for the three distinct types of achievement goals proposed by the trichotomous framework. Based on the results of the study, the 16-item Trichotomous Achievement Goal Scale can be claimed as a valid a reliable scale. 相似文献

Abstract Although the relative age effect has been widely observed in youth sports (Musch & Grondin, 2001), it is unclear whether it generalizes across the lifespan. The purpose of this study was to examine the relative age effect among a population of Masters athletes using archived data. Two successive studies examined the frequency of record-setting achievements (Study 1) and the frequency of participation entries (Study 2) at the US Masters track-and-field and swimming championships as a function of an individual's constituent year within any 5-year age category. Results of Study 1 indicated that the probability of setting a record increased if Masters athletes were in the first year, and decreased if they were in the third, fourth or fifth year, of an age category. Results of Study 2 indicated that the likelihood of participating in the National championships increased if Masters athletes were in the first or second year, and decreased if they were in the fourth or fifth year, of an age category. We highlight and discuss potential advantages afforded to Masters athletes who are relatively younger than their peers in the same 5-year age category. 相似文献
