Visual function,performance, and processing of basketball players vs. sedentary individuals

BackgroundAthletes tend to have better visuo-motor performance than do sedentary individuals. However, several basic visual-function and perceptual parameters remain unexplored to date. In this study, we investigated whether differences exist in visual function, performance, and processing between basketball players and individuals without a sport-involvement background.MethodsA total of 33 healthy men with no visual impairment or pathology were divided into 2 groups, depending on the involvement in sport (semi-professional basketball players and sedentary individuals). We tested their baseline heart-rate variability in the resting position apart from subjective questionnaires to determine their physical fitness level, and we checked their visual function, performance, and processing through an extended battery of optometric tests.ResultsThe 2 groups differed in resting heart-rate variability parameters (p < 0.001), confirming their dissimilarities in regular time practising sports per week. The basketball players showed a closer breakpoint and recovery nearpoint of convergence, a higher fusional-vergence rate, better discriminability halos, and better eye–hand coordination (all p values < 0.05).ConclusionThese results show evidence that athletes, basketball players in this case, exhibit better performance in several visual abilities in comparison to a group of individuals without sporting backgrounds, suggesting an improvement due to the systematic involvement of those skills during basketball practice.  相似文献

例谈新课程理念下小学数学练习设计     

杨金海 《中国教育发展研究杂志》2007,4(3):23-24

笔者认为，在进行数学练习题设计时，要注意把握以下几点：①练习题的设计要注意与实际的联系，强调对数学知识的应用。②练习题的设计要体现操作性，关注学生的学习体验。③练习题的设计要因材施教，兼顾学生差异，呈现训练梯度。④练习题的设计要有效促进学习方式的变革，从而提升学生的能力。  相似文献   

体育价值观与大学生体育锻炼行为的关系探讨     

孙柱兵 《毕节学院学报》2016,(4):144-150

通过随机抽样调查了209名大学生体育价值观与体育锻炼行为之间的关系,并对样本数据进行描述统计分析、因子分析、相关分析和线性回归分析,实证研究表明：体育价值观及其各因素与大学生体育锻炼行为两者之间存在显著的线性回归关系。理论拓展认为,体育锻炼行为的发生一方面得益于体育价值观内在驱动力的诱发作用,另一方面也是建立在客体环境上外因合力的结果。建议在大学体育教学中重视对学生体育价值观的培养,从而引导他们积极参与体育锻炼,增强学生的身体素质。  相似文献   

The effects of sotalol on ventricular repolarization during exercise     

Li J  Wang JA 《Journal of Zhejiang University. Science. B》2005,6(4):249-253

Objective: Although after pacing animal and human studies have demonstrated a rate-dependent effect of sotalol on ventricular repolarization, there is little information on the effects of sotalol on ventricular repolarization during exercise. This study attempted to show the effects of sotalol on ventricular repolarization during physiological exercise. Methods: Thirty-one healthy volunteers (18 males, 13 females) were enrolled in the study. Each performed a maximal treadmill exercise test according to the Bruce protocol after random treatment with sotalol, propranolol and placebo. Results: Sotalol significantly prolonged QTc(corrected QT) and JTc (corrected JT) intervals at rest compared with propranolol (QTc 324.86 ms vs 305.21 ms, P＜0.001; JTc245.04 ms vs 224.17 ms, P＜0.001) and placebo (QTc 324.86 ms vs 314.06 ms, P＜0.01; JTc 245.04 ms vs. 232.69 ms, P＜0.001).The JTc percent reduction increased progressively with each stage of exercise and correlated positively with exercise heart rate(r=0.148, P＜0.01). The JTc percent reduction correlation with exercise heart rate did not exist with either propranolol or placebo.Conclusions: These results imply that with sotalol ventricular repolarization is progressively shortened after exercise. Thus the specific class Ⅲ antiarrhythmic activity of sotalol, present as delay of ventricular repolarization, may be attenuated during exercise.Such findings may imply the need to consider other antiarrythmic therapy during periods of stress-induced tachycardia.  相似文献
