摘要：
The operation and maintenance of sports venues is the basis of ensuring the orderly organization of various events in large-scale comprehensive sports games. Due to the lack of evaluation methods and an index system, it was difficult to predict the input of operating and managing sports venues in large-scale comprehensive sports games. Excessive manpower is often put to guarantee the smooth operation work, causing the problem of waste on all resources. Based on the practice of the operational work for specified sports fields during the 7th World Army Games, this paper establishes a staffing allocation model for the maintenance and operation of sports venues. On the premise of building up a clear maintenance scope, a clarified organization structure and working procedure, the maintenance index of 15 specified venues is evaluated with analytic hierarchy process (AHP), and a set of allocation criteria of the operation team is put forward. The maintenance coefficients of studied venues range from 0.08 to 0.91, and the venues with highest coefficients are the main stadium, the naval pentathlon venues and the soccer field, etc.

摘要：
Physical activity performed in a natural environment, especially among green spaces, is associated with mental health benefits. Yet few studies have explored the separable influences of visual perception on the effects of green exercise. The present study assessed the extent to which two components of visual perception (form and color) contributed to mental health benefits by separating the form and color characteristics of an image of a green tree. In total, 76 healthy college students (18–24 years of age) engaged in incremental cycling exercise at a moderate intensity while viewing an image in front of them on a large screen. Participants were randomly assigned to one of four groups in which the image they viewed was a green tree, an achromatic tree, a formless color green, or a formless achromatic color. Before and after cycling (test time), participants’ selective attention, mood state, and self-esteem were assessed using the Perception and Attention Function battery and the Chinese versions of the Profile of Mood States scale and the Rosenberg Self-Esteem Scale, respectively. Significant interactions detected between test time and form perception indicated that scores in total mood disturbance decreased and scores in the esteem subscale and self-esteem scale increased after cycling while viewing trees. A significant interaction between test time and color perception indicated that anger decreased in the two green color conditions. A significant interaction of color perception by form perception by test time was associated with a significant decrease in response times on the attention task after cycling among participants who viewed the green tree. Our findings are important for interpreting mechanisms underlying characteristics attributable to environmental benefits and revealed that single (color or form) or combined (color and form) visual perception improved the mental health benefits of exercise. These findings may also inform the design and planning of urban green spaces to maximize green exercise effects.
摘要：
目的：探讨视频模拟训练对新手散打运动员预判能力和反应时的影响以及实验室训练的迁移效果。方法：采用专业摄像机记录2名专业运动员的进攻动作，用Adobe Premier CS 6软件剪辑视频，将剪辑好的视频用Matlab软件编辑成测试与训练程序。以30名新手散打运动员为被试，根据情景干扰理论随机分到随机训练组(训练材料按ABC、BAC排序)、组块训练组(训练材料按AAA、BBB排序)和对照组，每组10名运动员。随机训练组和组块训练组进行2周的知觉认知技能训练，对照组完成每项测试，但不接受视频模拟训练。采用视频分析技术计算运动员在实验室以及现场测试当中的准确率和反应时。结果：(1)训练后及现场测试中，随机组和组块组的预判准确率均显著高于对照组(P<0.05),反应时无统计学差异；(2)训练后，随机组和组块组的准确率无统计学差异；(3)现场测试中，随机组和组块组的预判准确率显著高于对照组(P<0.05),随机组和组块组的准确率无统计学差异。结论：视频模拟训练可以提高新手散打运动员的预判准确率；基于实验室的视频模拟训练能够提高新手散打运动员在现实运动情景中的预判能力，但对反应时的影响不明显。情景干扰效应对训练效果无显著影响，随机训练组在延迟测试中未表现出绩效优势。

摘要：
With the rapid development of media network technology, college students’ exercise is influenced by the use of fitness apps. How to improve the impact of fitness apps on college students’ exercise is a current research hotspot. The purpose of this study was to explore the influence mechanism of fitness apps usage intensity (FAUI) on college students’ exercise adherence.
