Team identification and sports fandom as predictors of fan aggression: The moderating role of ageing
《Sport Management Review》2019,22(2):194-208
In the current study, the explored the moderating role of ageing in the relationship between team identification/fandom and fan aggression. The authors used an online panel-based survey that offered access to a realworld population of sports fans. Participants were 740 fans of Israeli professional basketball. Results from structural equation modelling demonstrated that older fans reported higher levels of mere sports fandom and lower levels of self-reported aggression and acceptance of aggression. Moreover, age moderated the relationships between team identification (or fandom) and self-reported aggression, such that team identification (or fandom) was more strongly associated with selfreported fan aggression among younger fans than among older fans. The moderating role of age in the relationships between team identification (or fandom) and perceptions of appropriateness of aggression was not supported. The findings contribute to our theoretical understanding of the role of ageing in the relationship between fan identification and fan aggression. Based on these findings, the authors assert that managers might particularly benefit from leveraging the potential, but often neglected, segment of senior fans, since older fans can play a key role in reducing the level of aggression during competitive sports events. Suggestions for future research are also discussed. 相似文献

Geotechnical research on historical remains can provide new data and distinctive viewpoint for research on soil mechanics. Two Jiangnan Tu-Dun tombs historical remains were investigated by means of in situ and laboratory geotechnical tests. In the present paper the geotechnical properties of these man-made earthworks, especially ageing effect on consolidation and direct shear, and compaction properties of earth fill are discussed. 相似文献

ABSTRACTThis article explores, from a personal perspective, ageing and adventure in the context of the outdoor environment. Employing an autoethnographic sensibility, and drawing on fields of positive psychology, life course development, Outdoor and Adventurous Learning, and leisure studies, the paper discusses a range of motivations that contribute to my personal pursuit of a ‘fulfilled life’ now and in the future through ‘marine adventuring’. Adventuring is used to refer to my engagement with challenging physical outdoor activities; but also to my pursuit of learning; and, moreover, in my ‘existential’ quest for meaning. The specific activities under consideration are: seakayaking, SCUBA-diving and sailing. 相似文献

随着老年人口的迅速增长,老年教育的地位和作用日益凸显,建立老年教育学科的呼声也越来越高,这既是社会发展的趋势,也是老年教育独特的学科价值体现。从当前理论成果、现实驱动力来看,老年教育学科的“内外在建制”已经基本成熟,需要明确老年教育学科发展的目标,具体包括:加快构建“三大体系”,进入《学科分类与代码》（国家标准）;登上并站稳大学和干部教育讲台,成为师范生和老年教育工作者的必修课;设立老年教育专业,进入教育部招收本科生、研究生培养目录。要实现这系列标,从宏观上必须要做到以下几点:深入学习贯彻落实习近平关于文化自信和建设中国特色哲学社会科学的讲话精神;教育行政部门加大对老年教育学科建设的支持力度;充分发挥老年专家（人才）的主体力量;着力发掘年轻的新生力量,形成学术梯队;整合各方多学科力量,形成学科建设联盟。而在微观学科建设方面,可以遵循“学科、专业、课程”与“课程、专业、学科”两大建设思路,真正实现年龄友好的学习型社会的构建。 相似文献

Abstract The ageing neuromuscular system is affected by structural and functional changes that lead to a general slowing down of neuromuscular performance and an increased risk of falling. As a consequence, the process of ageing results in a reduced ability to develop maximal and explosive force, as well as in deficits in static and dynamic postural control. A decrease in the number and size of type II fibres in particular accounts for the age-related decline in muscle mass (sarcopaenia) and strength performance. Multiple denervation and re-innervation processes of muscle fibres seem to be responsible for the reduced number of muscle fibres. Recently, it has been suggested that it is not the decline in motoneurons that accounts for the loss in number of muscle fibres but the disturbed potential of fibre regeneration and re-innervation. Furthermore, an age-related reduction in the number of satellite cells has also been associated with sarcopaenia. The ability to compensate for platform and gait perturbations deteriorates with ageing as reflected in longer onset latencies and inefficient postural responses. All sites within the somatosensory system are affected by ageing and therefore contribute to postural instability. However, morphological changes of muscle spindles appear primarily to be responsible for the impaired ability to compensate for balance threats in old age. Given these neuromuscular limitations in old age, it is important to apply adequate training interventions that delay or even reverse the onset of these constraints. Strength training has the potential to enhance maximal as well as explosive force production capacity. This is accomplished by neural factors, including an improved recruitment pattern, discharge rate, and synchronization of motor units. Furthermore, an increase in number of satellite cells most likely accounts for training-induced muscle hypertrophy. Recent studies have investigated the impact of balance training in old age on the ability to develop maximal and explosive force. In addition, the effects of balance training on reflex activity during gait perturbations were also examined. Increases in maximal and explosive force production capacity and an improved ability to compensate for gait perturbations were observed. It is evident from the literature that researchers are increasingly studying the effects of more specifically designed training programmes on performance in populations of older adults. Thus, in the near future, strength training could be replaced by high-velocity forms of power training and balance training by perturbation-based training programmes. It is hypothesized that this new approach is more efficient in terms of fall prevention than the traditional approach. 相似文献

Abstract The objective of this study was to compare the three-dimensional lower extremity running kinematics of young adult runners and elderly runners. Seventeen elderly adults (age 67–73 years) and 17 young adults (age 26–36 years) ran at 3.1 m · s?1 on a treadmill while the movements of the lower extremity during the stance phase were recorded at 120 Hz using three-dimensional video. The three-dimensional kinematics of the lower limb segments and of the ankle and knee joints were determined, and selected variables were calculated to describe the movement. Our results suggest that elderly runners have a different movement pattern of the lower extremity from that of young adults during the stance phase of running. Compared with the young adults, the elderly runners had a substantial decrease in stride length (1.97 vs. 2.23 m; P = 0.01), an increase in stride frequency (1.58 vs. 1.37 Hz; P = 0.002), less knee flexion/extension range of motion (26 vs. 33°; P = 0.002), less tibial internal/external rotation range of motion (9 vs. 12°; P < 0.001), larger external rotation angle of the foot segment (toe-out angle) at the heel strike (?5.8 vs. ?1.0°; P = 0.009), and greater asynchronies between the ankle and knee movements during running. These results may help to explain why elderly individuals could be more susceptible to running-related injuries. 相似文献

The health benefits of playing football and the importance of exercise and social contact for healthy ageing are well established, but few older adults in the UK take enough exercise. Football is popular, flexible in format and draws players into engrossing, effortful and social exercise, but the physical demands of play at full speed may make it unsustainable for some older adults. Restricted to walking pace, will play still be engaging? Will health benefits be retained? Will physical demands remain manageable? This pilot study aims to investigate: (1) the experience of older adults playing walking football every week, is it sustainable and rewarding, (2) the intensity and locomotor pattern of walking football, (3) the scale and nature of walking football health benefits and (4) possible cognitive benefits of playing walking football through measures of processing speed, selective and divided attention and updating and inhibition components of executive function. ‘Walking football’ and ‘waiting list’ groups were compared before and after 12 weeks of one-hour per week football. Walking football was found to be engaging, sustainable for older adults and moderately intensive; however, selective health and cognitive benefits were not found from this brief intervention.Highlights
Walking football is a lower impact but authentic form of football that enables older players to extend their active participation.
Walking football is enjoyable and moderately demanding and may be a sustainable form of exercise for older adults.
Health and cognitive benefits to playing walking football were not found.
