A comparison of visual search strategies of elite and non-elite tennis players through cluster analysis     

Nicholas P. Murray 《Journal of sports sciences》2017,35(3):241-246

Considerable research has documented that successful performance in interceptive tasks (such as return of serve in tennis) is based on the performers’ capability to capture appropriate anticipatory information prior to the flight path of the approaching object. Athletes of higher skill tend to fixate on different locations in the playing environment prior to initiation of a skill than their lesser skilled counterparts. The purpose of this study was to examine visual search behaviour strategies of elite (world ranked) tennis players and non-ranked competitive tennis players (n = 43) utilising cluster analysis. The results of hierarchical (Ward’s method) and nonhierarchical (k means) cluster analyses revealed three different clusters. The clustering method distinguished visual behaviour of high, middle-and low-ranked players. Specifically, high-ranked players demonstrated longer mean fixation duration and lower variation of visual search than middle-and low-ranked players. In conclusion, the results demonstrated that cluster analysis is a useful tool for detecting and analysing the areas of interest for use in experimental analysis of expertise and to distinguish visual search variables among participants’.  相似文献   

A novel sleep optimisation programme to improve athletes’ well-being and performance     

Emer Van Ryswyk  Richard Weeks  Laura Bandick  Michaela O’Keefe  Andrew Vakulin  Peter Catcheside 《European Journal of Sport Science》2017,17(2):144-151

Objectives: To improve well-being and performance indicators in a group of Australian Football League (AFL) players via a six-week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior-level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n?=?25) received ongoing feedback on their sleep, and a mid-programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six-week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20?min (498.8?±?53.8 to 518.7?±?34.3; p?<?.05) and a 2% increase in sleep efficiency (p?<?0.05). There was a corresponding increase in vigour (p?<?0.001) and decrease in fatigue (p?<?0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well-being. More research is required into the effects of sleep optimisation on athletic performance.  相似文献

认知负荷对乒乓球运动员注意空间的影响*     

杨〓义  岳珍珠 《广州体育学院学报》2019,(2):99-101

目的 同时注意空间中多个目标刺激对于乒乓球运动员非常重要。考察认知负荷对青少年乒乓球运动员注意分布的影响。方法：实验中采用计算机行为实验，控制认知负荷（同时注意的目标数量为2、4或6个），并且在不同注意范围（离中央注视点3°、6°和9°视角）的位置上同时呈现刺激，要求被试对刺激的亮度变化做辨别反应。结果：:认知负荷对于乒乓球运动员的注意范围有显著调节。当刺激个数为2时，在3°和6°视角条件下呈现的刺激反应时均显著快于9°视角条件下的刺激。当刺激个数为4时，视角为3°条件下的反应时快于视角为6°和9°时的反应时，而视角为6°时又比视角为9°时的反应时显著要快。当刺激个数为6时，视角为3°时的反应时均快于视角为6°和9°时的反应时。结论：当前研究证明随着认知负荷增加，乒乓球运动员注意焦点范围显著缩小。可以通过测量运动员在高负荷条件下注意焦点的范围来进行运动员的选拔。  相似文献   

乒乓球运动员以预防损伤为主的功能训练          下载免费PDF全文

李男  叶晶龙 《体育科研》2019,(5):95-98

功能训练的理念来源于康复领域，现已逐步应用到运动训练中。由于乒乓球运动的项目特征，乒乓球运动员肩关节、腰椎关节、膝关节、踝关节、腕关节等部位容易出现运动损伤。通过对乒乓球运动员常出现的功能问题进行分析，寻找存在的常见问题，进而提出相应的功能训练建议。乒乓球运动员可根据情况，增加改善肩关节、胸椎关节、髋关节、踝关节的活动范围的训练，提高肩胛骨、核心和下肢稳定性的训练，以及改善肩袖、躯干肌力不平衡的训练，通过针对性的功能训练有效减少乒乓球运动员损伤的发生。  相似文献   

The effect of smartphones and playing video games on decision-making in soccer players: A crossover and randomised study     

Leonardo S. Fortes  Dalton De Lima-Junior  Lenamar Fiorese  José R. A. Nascimento-Júnior  Arnaldo L. Mortatti  Maria E. C. Ferreira 《Journal of sports sciences》2020,38(5):552-558

ABSTRACT

The objective of this study was to analyse the effect of the use of social networks in smartphones or playing video games on the passing decision-making performance in professional soccer athletes. Participants were 25 male professional soccer athletes (mean ± SD: age 23.4 ± 2.8 years). The participants performed three randomised conditions divided into three groups: control (CON), smartphone (SMA), and video game (VID). Before and after each experimental condition, the Stroop Task assessed the level of induced mental fatigue. Then, the athletes performed a simulated soccer match. A CANON® camera recorded the matches for further analysis on passing decision-making performance. A group effect was identified (p < .01) with impairment on passing decision-making performance for the SMA (p = .01, ES = 0.5) and VID (p = .01, ES = 0.5) conditions. We concluded that the use of social networks on smartphones and/or playing video games right before official soccer matches might impair the passing decision-making performance in professional soccer athletes.  相似文献   

Body composition differences by age and playing standard in male rugby union and rugby league: A systematic review and meta-analysis

ABSTRACT

This systematic review and meta-analysis aimed to determine differences in body compositionn between playing standard and age in male rugby union and rugby league athletes. The MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines for design, implementation, and reporting were followed. Studies were required to be in male rugby union or league and have body composition as the primary or secondary outcome. Data was required to be presented separately for positional groups and body composition presented as whole-body. A systematic search was performed in PubMed, Cochrane Library, MEDLINE, SPORTDiscus, and CINHAHL via EBSCOhost. 57 studies were included for meta-analysis. Results highlighted significantly higher fat-free mass in senior elite than senior sub-elite or junior elite athletes for all RU and RL forwards. Small and non-significant differences were found in fat mass between rugby union playing standards and age categories. Rugby league senior elite forwards had less fat mass than junior elite forwards. Practitioners should prioritise training and nutritional strategies that maximise fat-free mass development, especially in junior elite cohorts.  相似文献
