Why Olympia matters for modern sport     

Heather L. Reid 《体育哲学杂志》2017,44(2):159-173

From the modern scientific perspective, Olympia is a ruin at the far end of a fading sense of history that represents little more than the origins from which sport has continuously evolved. Quantitative measurements show continued increases in human performance, equipment efficiency and funding. But some question this athletic evolution. We worry about qualitative issues, such as virtue, meaning and beauty. The source of this contrast is a difference in values: Olympic vs. Efficiency values. Such values establish an ethos in sporting communities that influences how we behave, explain and even conceptualize our activities. I argue from the perspectives of metaphysics, epistemology, aesthetics, ethics and politics, that Olympic Ethos is needed to balance out the modern Efficiency Ethos, which threatens to dehumanize sport.  相似文献   

Individualised dietary strategies for Olympic combat sports: Acute weight loss,recovery and competition nutrition     

Reid Reale  Gary Slater  Louise M. Burke 《European Journal of Sport Science》2017,17(6):727-740

Olympic combat sports separate athletes into weight divisions, in an attempt to reduce size, strength, range and/or leverage disparities between competitors. Official weigh-ins are conducted anywhere from 3 and up to 24?h prior to competition ensuring athletes meet weight requirements (i.e. have ‘made weight’). Fighters commonly aim to compete in weight divisions lower than their day-to-day weight, achieved via chronic and acute manipulations of body mass (BM). Although these manipulations may impair health and absolute performance, their strategic use can improve competitive success. Key considerations are the acute manipulations around weigh-in, which differ in importance, magnitude and methods depending on the requirements of the individual combat sport and the weigh-in regulations. In particular, the time available for recovery following weigh-in/before competition will determine what degree of acute BM loss can be implemented and reversed. Increased exercise and restricted food and fluid intake are undertaken to decrease body water and gut contents reducing BM. When taken to the extreme, severe weight-making practices can be hazardous, and efforts have been made to reduce their prevalence. Indeed some have called for the abolition of these practices altogether. In lieu of adequate strategies to achieve this, and the pragmatic recognition of the likely continuation of these practices as long as regulations allow, this review summarises guidelines for athletes and coaches for manipulating BM and optimising post weigh-in recovery, to achieve better health and performance outcomes across the different Olympic combat sports.  相似文献   

Now you see,now you don’t … the influence of visual occlusion on racket and ball kinematics in the tennis serve     

Georgia Giblin  David Whiteside  Machar Reid 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):23-33

The serve is considered amongst the most important strokes in tennis. Not surprisingly, the development of a mechanically consistent and proficient serve is paramount. Correspondingly, drills that involve players serving with their eyes closed are thought to promote mechanical consistency. The purpose of this study was therefore to contrast the effect of the removal of visual feedback on ball and racket kinematics in the serve. A 10-camera 500-Hz VICON MX motion analysis system recorded the service actions of eight elite young players as they performed three serves with eyes open and three serves with eyes closed. Removal of vision resulted in considerable differences in both racket and ball kinematics, with players failing to make contact on 16 of 24 serves. Temporally, the preparation phase was significantly shorter with eyes closed. Spatially, the ball was located 6.5 cm further to the right at zenith, and 13 cm higher at impact with eyes closed. These results highlight that the serve is not entirely pre-programmable, and that visual feedback is critical to the spatiotemporal regulation of the serve. In turn, coaches need to be aware of the implications of modifying visual feedback in serve, and ensure that the consequence is congruent with their intent.  相似文献   

Art and Science in Challenging Needs Assessments: A Case Study     

Reid A. Bates  Elwood F. Holton 《Performance Improvement Quarterly》2002,15(1):111-130

This paper describes a needs assessment project that implemented two distinctive features to address challenges often faced in the needs assessment process. First, a pre‐assessment planning process was developed that successfully educated clients about the analysis process, generated management commitment, identified and prioritized key performance issues, and established an outcomes‐oriented strategic focus for the assessment. Second, to analyze team performance issues, a theory‐to‐practice process was developed that involved the use of discovery‐oriented inquiry within the project context (an inductive approach) with a deductive approach grounded in existing academic research and theory. The complementary and integrated use of these approaches yielded a more comprehensive understanding of the team performance problems, thorough analysis of those problems, and more focused and refined performance improvement recommendations.  相似文献
