越"好看"越容易激发情绪 作为与传统体育有诸多类似的电子竞技,对于赛事而言,越好看越容易激发观众的情绪是一条无需质疑的定律.大卫斯特恩在执掌NBA之后,对于规则的修改与"弱化"使得NBA的赛场上充满了火药味,这也带来了观众的狂热以及NBA日后的成功.NFL的成功更是因为美式足球这项运动本身具备的身体上的碰撞以及荷尔蒙的发泄.  相似文献

新课程实施已近6个年头,由于长期受到体育教学大纲思维的影响,当前仍不同程度的存在用"双基"达成情况作为衡量课堂教学"有为"与"无为"之标准,应及时打破这种教学观,树立与之相对的、符合新课标的新型"无为"教学观。本文通过对传统"有为"教学观的解析、新型"无为"教学观的界定以及两者的区别与联系进行论述,阐明了新型"无为"教学观适应体育课堂的时代要求,有助于学校体育科学发展,并在实践的基础上,将"无为"教学分为有趣、乐趣、志趣三个教学实施阶段的建议以及应注意的问题,以供大家参考借鉴。  相似文献

Little attention has been paid to the multidimensional nature of athletic involvement, which includes identity formation as well as participation in sports activities. Five hundred eighty-one sport-involved undergraduate students completed a questionnaire assessing their sport-related identities, goal orientations, primary sport ratings, and conformity to masculine norms. F-tested mean comparisons and hierarchical linear regressions were used to explore the characteristics associated with two distinct sport-related identities ("athletes" and "jocks"). Jock identity was associated with an ego-oriented approach to sports (men only), whereas athlete identity was associated with a task-oriented approach (both genders). Jock identity was positively associated with conformity to masculine norms, particularly for men, whereas athlete identity was positively associated with some masculine norms (i.e., Winning) and negatively associated with others (i.e., Playboy). These findings help to identify the correlates of a "toxic Jock" identity that may signal elevated risk for health-compromising behavior.  相似文献

Hiking physiology and the "quasi-isometric" concept   总被引:1,自引:0,他引:1  
The literature indicates that the heart rate of a planing-dinghy sailor, in winds of 4 - 5 m . s(-1), is in the range seen in aerobic athletes, yet oxygen consumption (VO(2)) is roughly half that of the same individual cycling at that heart rate. Thus, although upper-body dynamic activity is a contributing factor, the dominant physiological demand must be the "quasi-isometric" stress on the lower-body anterior muscles - especially the quadriceps, which appears to impose 40 - 50% of the total oxygen demand in a typical hiking posture. Therefore, a non-trivial part of the sailor's fitness training should involve sustained quadriceps stress. Estimates of this stress on water vary widely in the literature, but about 25 - 30% maximal voluntary contraction (MVC) tallies with endurance times recorded both in the literature and in an outline of new work reported here. Muscle blood flow is restricted under such a load, but not occluded. Laser Doppler measurements of femoral blood flow on a leg-extension ergometer found similar values during 10 - 30% MVC, much less at 40%, and marked hyperaemia on relaxation from 20% MVC or more - implying metabolic debt. Adding low-amplitude alternating leg movements while holding the same overall load stationary, and therefore increasing only internal not external work, further elevates blood flow and VO(2) both during and after exercise. Femoral-vein lactate concentration is also higher after these movements. Speculations that unusually dynamic lower-body movements by elite sailors might assist hiking endurance are not supported by these findings. Nevertheless, afloat or ashore, capillary lactate concentrations hardly ever exceed 5 mmol . l(-1), even during the post-exercise surge - challenging assumptions that the quadriceps had been profoundly anaerobic while under load. On the contrary, it appears that aerobic metabolism contributes substantially, if not completely, to energy supply. A preliminary comparison of elite sailors with aerobic athletes suggests that isometric endurance at a given percentage MVC does not differ between the two groups, but the sailors have higher MVCs. In individuals not highly strength-trained, greater electromyogram activity immediately before capitulation than in an MVC performed while fresh indicates that physiological (not just volitional) limits have been reached. It is concluded that the literature and the outline of my recent work with colleagues support the view that the predominant physiological load during single-handed dinghy sailing is quasi-isometric in form and accounts for roughly half of the metabolic demand. Any more complete account of the physiology of hiking will require simultaneous on-water measurement of electromyographic, cardiovascular, and metabolic indicators in sailors extending from club to Gold Medal standard.  相似文献
