In the current experiment, we examined optimal focus for novices during a movement sequence in which performance was measured on accurate movement form/technique. A novel gymnastics routine was practiced under either an internal skill-relevant, internal skill-irrelevant, external, or no attention focus. Retention and transfer tests were then completed. During acquisition, adopting an internal irrelevant focus significantly improved performance, whereas an external focus degraded performance. There were no significant group differences in the retention and transfer tests. This suggests that learning of movement form/technique did not benefit from a specific focus of attention. The results are interpreted via an attentional capacity viewpoint and the notion that form tasks do not always contain obvious movement effects central to common coding and the constrained action hypothesis. 相似文献

随着特殊的训练计划被教练员们采用以促进运动员的肌肉适应能力,肌肉训练也成为渐进式康复的重要组成部分,它能阻止与丧失运动能力、老化、疾病或微重力相关的萎缩效应。为了优化不同类型的干扰措施,需要更好地理解运动训练产生的反应,以及识别决定肌肉功能的各种机制。虽然整体肌肉活动在某种程度上是通过适应运动神经元爆发、运动单元补充模式或者肌肉量来进行的,本研究着重探讨肌肉纤维类型的表达以及训练后收缩肌的功能性适应能力。单一无皮纤维被证明是常用的实验模型,用于研究与肌浆球蛋白重链对碘氧基苯甲醚相关的试管内收缩特性。人体纤维主要的功能和生化特性在过去二十年中已经被详细研究了,但近来,无皮纤维模式正被用于研究不同类型的诱发训练后单纤维的功能适应性。本文的目的是概述收缩肌对于特定运动训练计划的反应,以及帮助形成适用于运动科学和康复的训练计划。 相似文献

The development of external, nontraditional degree programs has stimulated discussion as to the usefulness of the diplomas received through such programs. Questionnaires completed by 686 graduates of Illinois' statewide Board of Governors Bachelor of Arts Degree Program measure the extent to which the degree is acceptable to graduates and their employers, the degree to which student goals were met upon graduation, the quality of program services, and the success rate of students applying to graduate schools. The results are overwhelmingly positive, suggesting that non-traditional degrees are gaining general acceptance among a wide variety of groups.For assistance in collecting, tabulating and analyzing data for this article, the authors are grateful to C. Edward Gilpatric, Judith Hofstrand, Elizabeth Stanley, and Donald Tedder. 相似文献

This paper deals with an application of PERT to R & D scheduling for the National Center for Drug Analysis, U. S. Food and Drug Administration. The Center is a pharmaceutical-chemistry laboratory having specialized functional responsibilities for research and development of analytical chemical procedures. The model was constructed based on the empirical data obtained at the Center for a five-year period. The model has been statistically tested and interpreted. It assists the management of the Center in developing a complete work-planning process and in controlling the project tasks, thus achieving the effective utilization of human and physical resources. 相似文献
