通过文献资料、逻辑分析等方法,对马拉松的起源、马拉松到城市马拉松的演进、城市马拉松在国内外的发展进行考察。在此基础上对城市文化内涵及马拉松与城市文化的契合进行深入地分析：认为马拉松是健康、积极向上的城市形象的展现;马拉松的包容精神打破城市的社会排斥;马拉松促进城市的和谐及培养市民对城市的认同感、增强城市的凝聚力;举办城市马拉松本身是一种城市文化标识;马拉松彰显的是城市积极的进取精神等。最后,依据我国城市马拉松举办过程中存在的问题提出优化路径。 相似文献

Prolonged running results in lowering of the foot arch and a low arch is associated with subsequent chronic injuries. Foot posture alteration and recovery following a marathon run remain unknown. Therefore, the present study aimed to evaluate foot posture alteration following a full marathon run. The three-dimensional foot posture data of 11 collegiate runners were obtained using an optical foot scanner system before, and immediately, 1 day, 3 days, and 8 days after a full marathon. The navicular height and arch height ratio significantly decreased from before to immediately, 1 day, 3 days, and 8 days after the marathon (navicular height: before, 44.2?±?5.0?mm; immediately after, 39.4?±?5.5?mm; 1 day, 37.7?±?6.2?mm; 3 days, 38.7?±?5.5?mm; 8 days, 37.6?±?5.7?mm; arch height ratio: before, 18.4?±?1.9; immediately after, 16.5?±?2.5; 1 day, 15.7?±?2.5; 3 days, 16.2?±?2.6; 8 days, 15.6?±?2.2, P?, respectively). By contrast, the dorsal height significantly increased from before and immediately after to 1 day after the marathon, and then significantly decreased until 8 days after the marathon (P?). These results indicate that the recovery patterns of the dorsal and navicular heights following a marathon did not coincide; the dorsal height rose temporally at 1 day after and subsequently decreased, but the navicular height decreased throughout the 8-day period after the marathon. More than one week may be necessary for sufficient foot alignment recovery from marathon-induced changes. 相似文献

马拉松运动通过符号化成为人们的一种文化消费方式,并受到城市中产阶层的青睐捧。基于文化身份认同的视角,借助布迪厄的阶级理论,深入探究城市中产阶层热衷于马拉松的动因。研究认为,马拉松经由个人趣味,演变而成阶层惯习,进而产生社会区隔,被区隔出来的马拉松爱好者群体,通过对自我意识和所处阶层意识的强化以及这种阶层文化消费水平的保持实现了其文化身份的认同。对城市中产阶层热衷于马拉松而产生的问题有一个新视角的思考,并通过规避方案的设计,促进健康、理性的马拉松消费氛围的形成,使得城市中产阶层的文化身份认同感更为稳定,同时推动马拉松赛事的可持续发展。 相似文献

Literature has established that a range of physiological, biomechanical, and training variables influence marathon performance. The influence of anthropometric characteristics has also received attention. However, despite major marathons exceeding 40,000 participants and approximately a third of these runners being female, no data exist on the influence of the breast on running performance. This cross-sectional study aimed to explore the impact of breast mass on marathon finish time. One hundred and sixty-eight of 321 female marathon runners contacted completed an on-line survey focusing on marathon performance during the 2012 London marathon. Participants were categorised as smaller (<500?g, 54%) or larger breasted (>500?g, 46%). Regression analysis identified that 24% of marathon performance variance could be explained by body mass index (BMI), but breast mass improved the model to explain 28% of performance variation. The model determined that for women with 32/34 or 36/38 underband each increase in cup size equates to a performance decrement of 4.6?min or 8.6 min, equivalent to 34.4?min difference between a woman with 36A compared to 36DD breast size. Larger breasted runners had greater BMIs, completed less marathons and had slower marathon finish times (316?±?48?min) compared to smaller breasted runners (281?±?51?min). Twenty-five per cent less larger breasted women finished in the fastest quartile. These results suggest that differences in breast mass are an important factor for female athletes and should be considered in future research in this area. 相似文献
