ABSTRACTThe aim of this study was to investigate the differences and long-term reliability in perceptual, metabolic, and neuromuscular responses to velocity loss resistance training protocols. Using a repeated, counterbalanced, crossover design, twelve team-sport athletes completed 5-sets of barbell back-squats at a load corresponding to a mean concentric velocity of ~0.70 m·s?1. On different days, repetitions were performed until a 10%, 20% or 30% velocity loss was attained, with outcome measures collected after each set. Sessions were repeated after four-weeks. There were substantial between-protocol differences in post-set differential ratings of perceived exertion (dRPE, i.e., breathlessness and leg muscles, AU) and blood lactate concentration (B[La], mmol·L?1), such that 30%>20%>10% by small to large magnitudes. Differences in post-set countermovement jump (CMJ) variables were small for most variables, such that 30%<20%<10%. Standard deviations representing four-week variability of post-set responses to each protocol were: dRPE, 8–11; B[La], 0.8–1.0; CMJ height, 1.6–2.0; CMJ PPO, 1.0–1.8; CMJ PCV, 0.04–0.06; CMJ 100ms-Impulse, 5.7–11.9. Velocity loss thresholds control the magnitude of perceptual, metabolic, and neuromuscular responses to resistance training. For practitioners wanting to reliably prescribe training that can induce a given perceptual, metabolic, or neuromuscular response, it is strongly advised that velocity-based thresholds are implemented. 相似文献

企业移动终端App用户信息隐私关注模型构建 总被引:1,自引:0,他引:1
[目的/意义] 针对企业移动终端App用户,对其信息隐私关注的内在机理进行研究,以进一步丰富信息隐私关注的理论体系,并为企业利用移动终端App进行营销活动和客户关系管理具有重要的指导。[方法/过程] 基于感知价值理论和计划行为理论,将信息隐私关注分为感知信息隐私收益和感知信息隐私支出两个维度,结合移动终端App的特点,探讨用户的行为态度、主观规范和感知行为控制对信息隐私关注两个维度的影响机理,以及信息隐私关注与用户信息披露行为之间的逻辑关系。[结果/结论] 最终构建企业移动终端App用户信息隐私关注模型。 相似文献

This research investigated the relationships among symptoms associated with attention‐deficit/hyperactivity disorder (ADHD), perceived stress, and resilience in college students. In our study of 558 college students (175 men, 383 women), we confirmed the hypothesis that the relationship between ADHD symptoms and perceived stress is mediated by protective factors associated with resilience. The relationships were not significantly moderated by sex. Implications for increasing resilience in college students and lowering perceived stress for college students are discussed. 相似文献

在介绍和评论组织公正感研究成果的基础上,提出公众的社会公正感是反映社会公正价值体现的一个灵敏指标,在公共管理领域开展社会公正感研究十分必要;认为在决策程序上规范政府行为、保障公民有效参与是提高公共管理水平的关键,加强政府与公众之间的信息交流与互动是提高社会公正感、促进公共管理目标实现的有效途径;指出当前要特别重视因分配结果和社会利益阶层收入差距引发的社会不公正感和不稳定因素,做好监测和预警工作。 相似文献

The current loss of biodiversity requires efforts to increase awareness of pollinator conservation. An important tool is education which often uses the honeybee (Apis mellifera) as an exemplary organism to reach this goal. Any successful module needs to focus on reducing the perceived danger associated with fear, in order to support the willingness to protect them. Using a quasi-experimental design, we investigated the effectiveness of two educational approaches: one by authentically encountering living animals at a beehive, the other by using a remote online beehive. We monitored secondary school students’ (N = 354) perception of bees with respect to interest, danger and conservation as well as situational emotions (interest, well-being, boredom) during both interventions. In both cases positive effects on perception levels were observed, even when already a high willingness to protect bees existed. Using living animals in educational settings is crucial, especially when students’ situational emotions need targeting. However, we achieved similar intervention results in perception levels using a remote beehive, which therefore constitutes an excellent alternative to raise awareness of the conservation of bees as pollinators when working with living organisms is not possible. 相似文献

The Course ExperienceQuestionnaire (CEQ) and a short form of theApproaches to Studying Inventory (ASI) wereadapted for use in distance education and wereadministered to students taking six differentcourses with the Open University. Theconstituent structure of the CEQ was preservedin this distinctive context, and a second-orderfactor analysis confirmed its status as ameasure of perceived academic quality. Thestudents' scores on the individual scales ofthe CEQ and the ASI shared almost half of theirrespective variance. It is concluded thatapproaches to studying in distance educationare strongly associated with students'perceptions of the academic quality of theircourses. 相似文献
