Background: This paper is part two of a discussion about a new pedagogical model for adventure in the curriculum. It builds upon part one, the advocacy paper, which considered important theoretical foundations, historical influences and research outcomes of outdoor adventure education (OAE) in the UK.
Purpose: This paper outlines how a model for OAE might be implemented in practice in schools in the UK. Four non-negotiable features of a pedagogical model for OAE are identified as essential for pupils to gain maximum benefit from their outdoor adventure experiences. Consideration is also given to other essential features of models-based approaches to physical education that teachers need to consider to underpin the model's authenticity, including pupils’ readiness for learning, teacher expertise and knowledge, and assessment and future model validation.
Conclusions: Four non-negotiable features of a model for OAE are identified as being mainly outdoors, experiential learning, challenge by choice and managed risk. Key concerns arising from the implementation of these non-negotiable features are considered. These include encouraging pupils to take more responsibility for their own learning, developing closer links between school OAE and local opportunities, supporting teachers in making judgements about pupils managing their own risk, developing teachers’ expertise in reviewing and developing assessment tools that measure pupils’ affective learning. 相似文献

Abstract Our aim was to present a mathematical model of rowing and sculling that allowed for a comparison of oar blade designs. The relative movement between the oar blades and water during the drive phase of the stroke was modelled, and the lift and drag forces generated by this complex interaction were determined. The model was driven by the oar shaft angular velocity about the oarlock in the horizontal plane, and was shown to be valid against measured on-water mean steady-state shell velocity for both a heavyweight men's eight and a lightweight men's single scull. Measured lift and drag force coefficients previously presented by the authors were used as inputs to the model, whichs allowed for the influence of oar blade design on rowing performance to be determined. The commonly used Big Blade, which is curved, and it's flat equivalent were compared, and blade curvature was shown to generate a 1.14% improvement in mean boat velocity, or a 17.1-m lead over 1500 m. With races being won and lost by much smaller margins than this, blade curvature would appear to play a significant role in propulsion. 相似文献

The year 1948, as a starting point both of this study and of the organised military sport for Greece, was particularly hectic, since the newly liberated country was embroiled in the Civil War while, simultaneously, it was trying to reconstitute itself. The next two decades were marked by the foundation and the activities of the Higher Coordinating Committee for Sport in the Armed Forces (Anotera Syntonistiki Epitropi Athlitismou Enoplon Dynameon – A.S.E.A.E.D.). This Committee organised and materialised the first steps of the newly established organised sports activities of the Hellenic Armed Forces and evolved as a result, into the Supreme Council for Sport in the Armed Forces (Anotato Symvoulio Athlitismou Enoplon Dynameon) in year 1968. Due to the lack of specific and thorough research on the topic during this era, the purpose of this study was to identify references and the original sources (archives both of the A.S.E.A.E.D. and of the Hellenic National Defense General Staff) and to highlight and reveal the activities of organised Greek military sport, in the organisational field, and the Hellenic Armed Forces' participation in international sports tournaments. 相似文献

This paper addresses issues raised in Paul Ward's essay ‘Last man picked’, focusing on methodological and discipline-refining questions to call for a more open dialogue between sports historians and others in the discipline. The argument includes a call on the wider discipline to both recognise the need for and participation in sub-discipline specific debates. 相似文献

Although it might be believed that the eye only comprised a very small area of the face, its injury due to the ball impacts in different sports seems to be severe enough to entice many researchers to determine the level of injury and then attempt to minimize it. Sports-related eye injuries, especially tennis, pose a substantial and preventable problem to the eye due to the high speed of the tennis ball (69 m/s). This is why many ophthalmologists provide a wide range of information for their patients regarding the risks of eye injuries in tennis to prevent the injury to well over 100,000 eyes each year. However, so far although there are some general information regarding the injury to the human eye components due to the tennis ball impact, the details of the stresses and deformations have not been well determined. Therefore, the goal of this study was to determine the stresses and deformations of the eye components, including cornea, aqueous body, iris, ciliary body, lens, vitreous body, retina, sclera, optic nerve, extra and intraconal fats, and muscles, attributable to the tennis ball impact via a Lagrangian–Eulerian computational coupling model. Magnetic resonance imaging was employed to establish a finite element model of the human eye according to a normal human eye. The numerical results revealed the highest amount of stress in the iris (19.2 MPa), whereas the lowest one was observed in the vitreous body (1.77 Pa). The cornea also experienced the stress of 8.27 MPa which might be high enough to invoke rupture in this delicate material. In addition, the results exhibited a decreasing and increasing of the radius of curvature for the cornea and lens, respectively. Finally, the collision of the tennis ball to the eye triggered the resultant displacement of 0.045 µm in the optic nerve which may imply a non-significant injury to that. The findings of this study may have implications not only for understating the values of stresses and deformations in the human eye components but also for helping the ophthalmologists to have a more precise diagnosis about the injury position in the eye due to the tennis ball impact. 相似文献

The present study revisited the problem of estimating Olympic success by critical demo-economic indicators. The sample consisted of the 75 winner countries at the Athens 2004 Olympic Games (not previously analyzed). Medal totals were log-linearly regressed on land, population, GDP, urban population, inflation, growth rate, unemployment, labor force, health expenditures, ex-host, and team size. Multiple regression assumptions were tested with proper diagnostics including collinearity. Olympic team size was the best single predictors of Olympic medals (R2 = 0.690, p < 0.001), and as an alternative criterion variable was significantly regressed on population, growth rate, health expenditure, and unemployment (R2 = 0.563, p < 0.001). Medal totals were significantly regressed on population, ex-host, health expenditure, growth rate, and unemployment (R2 = 0.541, p < 0.001). The classical population-GDP model extracted only 28% of the variance in total medals (R2 = 0.277, p < 0.001), and this was slightly improved when combined with unemployment (R2 = 0.365, p < 0.001). It appears that the size of the Olympic team plays the role of transmitting the composite impact of a country's size and economy to the end-phase of Olympic success. Winning Olympic medals depends on the combined potential of population, wealth, growth rate, unemployment, ex-host, and social-sport expenditures. Larger and wealthier countries win more medals by “producing” larger Olympic teams as a result of possessing more athletic talents and better support for social and sport related activities. 相似文献

This paper investigates the potential of international youth football tournaments for youth development in the Global South. The tournaments under study were East Africa Cup in Tanzania, and Norway Cup in Norway. Through qualitative interviews with tournament participants, we addressed the following research question: What are the participant’s views of the potentials of Norway Cup and East Africa Cup in dealing with development issues facing youth in the Global South? Our findings demonstrate that all interviewees consider the tournaments potentially beneficial for youth development in the Global South. In the analysis, we identified four different categories, mostly representing positive outcomes of tournament participation. We argue that a functionalist neo-liberal notion of sport is visible in the data material. Thus, our findings correspond with Sport for Development and Peace (SDP) research showing how reproductions of the SDP functionalist discourse ‘continue to be leveraged through sport and sealed into the success story of SDP’. 相似文献

We aimed to analyse the handgrip positioning and the wedge effects on the backstroke start performance and technique. Ten swimmers completed randomly eight 15 m backstroke starts (four with hands on highest horizontal and four on vertical handgrip) performed with and without wedge. One surface and one underwater camera recorded kinematic data. Standardised mean difference (SMD) and 95% confidence intervals (CI) were used. Handgrip positioning did not affect kinematics with and without wedge use. Handgrips horizontally positioned and feet over wedge displayed greater knee angular velocity than without it (SMD = ?0.82; 95% CI: ?1.56, ?0.08). Hands vertically positioned and feet over wedge presented greater take-off angle (SMD = ?0.81; 95% CI: ?1.55, ?0.07), centre of mass (CM) vertical positioning at first water contact (SMD = ?0.97; 95% CI: ?1.87, ?0.07) and CM vertical velocity at CM immersion (SMD = 1.03; 95% CI: 0.08, 1.98) when comparing without wedge use. Swimmers extended the hip previous to the knee and ankle joints, except for the variant with hands vertically positioned without wedge (SMD = 0.75; 95% CI: ?0.03, 1.53). Swimmers should preserve biomechanical advantages achieved during flight with variant with hands vertically positioned and wedge throughout entry and underwater phase. 相似文献

The app for the System for Observing Play and Recreation in Communities (iSOPARC®) was developed to enhance System for Observing Play and Recreation in Communities data collection and management. The study aim was to examine the usability and inter-rater reliability of iSOPARC®. Trained observers collected data in 16 park areas in two Latin America cities (Curitiba, Brazil; Bogotá, Colombia) using both the original System for Observing Play and Recreation in Communities (mechanical counter) and new iSOPARC® (electronic counter) methods. A total of 8,707 park users (3,958 females and 4,749 males) were observed. Reliabilities among observers were determined using the intraclass correlation coefficient and relative overall agreement (%) in three ways: (a) mechanical versus mechanical, (b) mechanical versus electronic, and (c) electronic versus electronic. When both used mechanical counters comparisons overall agreement was over 78% (intraclass correlation coefficient = .982; p < .001) for variables in all analysis. When one used a mechanical counter and the other used electronic (iSOPARC®) comparisons overall agreement was higher for age (84%; p < .001) than for physical activity (83%; p < .001) variables and average intraclass correlation coefficient was .965. Using both used iSOPARC® comparisons overall agreement was 81% to physical activity and 83% to age group. Results suggest iSOPARC® can be used reliably for examining variables previously validated in System for Observing Play and Recreation in Communities. 相似文献

Accelerometer-based systems are often used to quantify human movement. This study’s aim was to assess the reliability and validity of the Myotest® accelerometer-based system for measuring running stride kinematics. Twenty habitual runners ran two 60 m trials at 12, 15, 18 and 21 km·h?1. Contact time, aerial time and step frequency parameters from six consecutive running steps of each trial were extracted using Myotest® data. Between-trial reproducibility of measures was determined by comparing kinematic parameters from the two runs performed at the same speed. Myotest® measures were compared against photocell-based (Optojump Next®) and high-frequency video data to establish concurrent validity. The Myotest®-derived parameters were highly reproducible between trials at all running speeds (intra-class correlation coefficient (ICC): 0.886 to 0.974). Compared to the photo-cell and high-speed video-based measures, the mean contact times from the Myotest® were 34% shorter and aerial times were 64% longer. Only step frequency was comparable between systems and demonstrated high between-system correlation (ICC ≥ 0.857). The Myotest® is a practical portable device that is reliable for measuring contact time, aerial time and step frequency during running. In terms of validity, it provides accurate step frequency measures but underestimates contact time and overestimates aerial time compared to photocell- and optical-based systems. 相似文献

Tudor-Locke and colleagues previously assessed steps/day for 1 year. The aim of this study was to use this data set to introduce a novel approach for the investigation of whether individual’s physical activity exhibits periodicity fluctuating round a mean and, if so, the degree of fluctuation and whether the mean changes over time. Twenty-three participants wore a pedometer for 365 days, recorded steps/day and whether the day was a workday. Fourier transform of each participant’s daily steps data showed the physical activity had a periodicity of 7 days in half of the participants, matching the periodicity of the workday pattern. Activity level remained stable in half of the participants, decreased in ten participants and increased in two. In conclusion, the 7-day periodicity of activity in half of the participants and correspondence with the workday pattern suggest a social or environmental influence. The novel analytical approach introduced herein allows the determination of the periodicity of activity, the degree of variability in activity that is tolerated during day-to-day life and whether the activity level is stable. Results from the use of these methodologies in larger data sets may enable a more focused approach to the design of interventions that aim to increase activity. 相似文献

Does the individual zones of optimal functioning model discriminate between successful and less successful athletes? A meta-analysis 总被引：1，自引：0，他引：1
According to the individual zones of optimal functioning (IZOF) model, an athlete's performance is successful when his or her pre-competition anxiety is within or near the individually optimal zone. When anxiety falls outside the optimal zone, performance deteriorates. The model also suggests that skilled athletes are aware of, and are able to accurately recall and anticipate, their pre-competition anxiety. A meta-analysis of 19 studies from 1978 to 1997 (146 effect sizes based on 6387 participants) was conducted to examine the validity of the assumptions regarding the in-out of the zone notion and the accuracy of recalls and anticipatory measures of anxiety. The findings provide fairly good empirical support for the IZOF anxiety model, with an overall effect size (d) for the in-out of the zone notion of d = +0.44 (41 effect sizes, n = 3175). In other words, the performance of athletes who were within their individually optimal zones were almost one-half a standard deviation unit better than that of athletes who were outside their zones. Furthermore, both effect sizes (r(w)) for accuracy of precompetition anxiety measures, recall (r(w) = +0.71, 24 effect sizes, n = 369) and anticipatory (r(w) = +0.69, 81 effect sizes, n = 2843), exceeded the 'large effect' suggested for correlations by Cohen. The implications for future research extending the IZOF model to a wider range of positive and negative emotions are discussed. 相似文献

The outcome of penalty shoot-outs is often referred to as a “lottery”, suggesting that luck, rather than the skill level of the player, predetermines outcome success. Throughout this article, we hope to show why such attitudes towards physical and psychological preparation can increase anxiety, diminish perceptions of control and negatively affect the behaviour and subsequent performance of penalty takers. From the synthesis of this evidence, we provide task-specific recommendations that are structured around the dynamic nature of emotions that players are likely to experience during each phase of the shoot-out and which can be implemented or adapted to suit the individual needs of the player. These recommendations are designed to provide a framework to help applied professionals to optimise the psychological preparation for this scenario with the overall aim of helping players to (re)gain control of this situation. 相似文献

AbstractThis study examined whether athletes’ attachment styles with the coach were linked to aspects of the coach–athlete relationship quality and, in turn, whether relationship quality was linked to athletes’ well-being. One hundred and ninety-two athletes completed a questionnaire measuring their attachment styles and relationship quality with the coach as well as their feelings of positive affect (PA) and negative affect (NA). Structural equation modelling (SEM) analysis found athletes’ avoidant and secure attachment styles to be associated with aspects of coach–athlete relationship quality such as social support, relationship depth, and interpersonal conflict. Interpersonal conflict appeared to play a key role in athletes’ PA and NA. From a practical perspective, an understanding of conflict management could provide a resource that allows athletes (and coaches) to enhance the quality of their sporting relationships. Specifically, an awareness of proactive strategies (e.g., steps to clarify expectations) and reactive strategies (e.g., cooperation during the discussion of disagreements) could potentially lead both coaches and athletes to “broaden” their viewpoints and in turn “build” connections that are capable of generating positive emotions including interest, excitement, happiness, and zeal. 相似文献

This study examines the coverage given to the US women’s national soccer team by its governing body, the US Soccer Federation (USSF), immediately before, during and immediately after the 2011 World Cup. Content analysis of two of the USSF’s Twitter accounts showed that although the differences in both quantity and quality of coverage between men’s and women’s soccer are not as great as those detected in traditional media between men’s and women’s athletics, a gender gap remains. Similar to traditional media, the USSF framed the women’s team as less important than the men’s, even though this study was purposefully conducted at a time when female soccer was supposed to be prominent because of the international schedule. 相似文献
