Motivation counteracts fatigue-induced performance decrements in soccer passing performance

Recent theories suggest that negative effects of fatigue on performance are determined by perception of effort and motivation rather than being directly caused by reaching physiological limits. In the current experiment, the influence of motivation on fatigue-induced decrements in soccer performance was experimentally investigated. Sixty amateur soccer players performed a validated soccer-passing test before and after a fatigue protocol. Results showed that players’ motivation and performance decreased after the fatigue protocol for players in the control group. In contrast, players in the motivation group (i.e., with motivation experimentally induced after the fatigue protocol) were able to uphold their motivation and increase their performance. These results indicate that motivation plays a crucial role in performance under fatigue, as fatigue-induced decrements in soccer passing performance can be counteracted by high levels of motivation. Future research may explore the limits of this counteracting effect and extend findings to other relevant performance aspects.     

Effects of oncoming target velocities on rapid force production and accuracy of force production intensity and timing

The present study aimed to clarify the effects of oncoming target velocities on the ability of rapid force production and accuracy and variability of simultaneous control of both force production intensity and timing. Twenty male participants (age: 21.0 ± 1.4 years) performed rapid gripping with a handgrip dynamometer to coincide with the arrival of an oncoming target by using a horizontal electronic trackway. The oncoming target velocities were 4, 8, and 12 m · s^?1, which were randomly produced. The grip force required was 30% of the maximal voluntary contraction. Although the peak force (Pf) and rate of force development (RFD) increased with increasing target velocity, the value of the RFD to Pf ratio was constant across the 3 target velocities. The accuracy of both force production intensity and timing decreased at higher target velocities. Moreover, the intrapersonal variability in temporal parameters was lower in the fast target velocity condition, but constant variability in 3 target velocities was observed in force intensity parameters. These results suggest that oncoming target velocity does not intrinsically affect the ability for rapid force production. However, the oncoming target velocity affects accuracy and variability of force production intensity and timing during rapid force production.

网络时代的图书馆内部组织结构也需网络化

随着网络信息资源的不断开发与利用,传统图书馆的组织管理模式已不能满足读者需求,于是,一种新的网络化的组织结构模式开始产生,即在保留图书馆内部原有的职能部门基础上,建立一些跨职能部门的工作任务委员会,以更好地发挥图书馆员的潜力,提高机构总体工作质量和效率。参考文献3。

立法语篇中权威性的体现

立法语言指规范性法律文本使用的语言。法律规范是由国家制定和认可,并由国家强制力保证实施的最高的行为准则,具有无可置疑的法律效力,因此在语言运用中必须充分显示出法律规范的权威性。以系统功能语言学派德语域理论为基础,从语篇的语言实现形式入手揭示《中华人民共和国宪法》“公民的基本权利和义务”的法律规范蕴涵的法律权威性。
