This study compared motor actions and spatiotemporal changes between weight divisions from Ultimate Fighting Championship (UFC™), conducting a practical application for mixed martial arts (MMA) training. For this, we analyzed 2814 rounds of all weight divisions by motor actions and spatiotemporal changes according actions and time of the Keeping distance, Clinch and Groundwork combat phases. We observed differences between weight divisions in the keeping distance on stand-up combat (p ≤ 0.001; with lower time in Featherweight 131.4 s and bantamweight 127.9 s) clinch without attack (p ≤ 0.001; with higher timer in Flyweight 11.4 s and Half-middleweight 12.6 s) and groundwork without attack (p ≤ 0.001; with higher timer in Half-middleweight 0.9 s). During keeping distance, half-middleweight presented a higher frequency of Head Strikes Landed (p = 0.026; 7 ± 8 times) and attempted (p = 0.003; 24 ± 22 times). In clinch actions heavyweight present a higher frequency (p ≤ 0.023) of head strike landed (3 ± 7 times) and attempted (4 ± 9 times) and half-middleweight for body strikes (p ≤ 0.023) landed (2 ± 5 times) and attempted (3 ± 5 times). At the last, during groundwork, Bantamweight present a higher frequency (p ≤ 0.036) of head strikes landed (8 ± 10 times) and attempted (10 ± 13 times) body strikes landed (p ≤ 0.044; 3 ± 5 times) and attempted (3 ± 6 times). This study reveals important point to training and provide a challenge applied referential to the conditioning plains. From the weight divisions differences should be aware of the increase in the frequency of distance actions, especially in light and middleweights. On the Ground, bantamweight can focus on striking and grappling actions than others. 相似文献

Recent research suggests that some imagined future events are encoded in memory, leading to the formation of “memories of the future”. However, questions remain regarding the exact components of future event simulations that are encoded and the factors that determine their accessibility. To address these questions, the present study investigated memory for previously imagined future events using both free and cued recall tasks. The results showed that most future event simulations were successfully encoded and remained available in memory after a one week delay, but only some of them were readily accessible, whereas others could only be accessed when relevant cues were provided. Persons and locations were particularly well remembered, suggesting that these components are central to the simulation and memorisation of future events. We also found that memory for future event simulations was related to the clarity and familiarity of represented persons, the subjective feelings of pre-experience and mental time travel, the importance of imagined events to personal goals, and their emotional intensity during the initial simulation phase. Taken together, these findings expand our understanding of the formation, accessibility, and characteristics of memories of the future. 相似文献

不安全依恋者的注意偏向是指依恋焦虑和回避个体对依恋信息产生或趋近或回避的注意偏好, 这一注意偏好使得个体形成了处理与依恋对象关系的特殊认知机制:依恋回避个体偏好采用防御性机制, 倾向于回避对依恋信息的注意; 依恋焦虑个体偏好采用夸大性机制, 倾向于夸大威胁性信息, 因而会积极寻求与依恋对象的亲近。不安全依恋者注意偏向的差异主要体现在情绪信息、痛觉感受和工作记忆三个方面; 加工阶段特征主要涉及P1、N1波等代表的注意自动加工和LPP波代表的注意控制加工; 脑网络上主要包括两个子网络, 即负责情绪评估的边缘系统和负责情绪调节的以前额叶为代表的神经网络。未来研究中更应该关注刺激物的生态效度, 检验依恋系统是否激活, 不安全依恋者注意偏向的自动加工和控制加工阶段的关系, 不安全依恋者注意偏向产生的分子遗传机制以及注意偏向的跨文化研究。 相似文献

IGNACIO MATTE BLANCO 《The International journal of psycho-analysis》2005,86(5):1463-1476
Matte Blanco examines four paradoxical positions that arise out of Freud's writings on the death instinct. He notes that death is not a content known to the unconscious. Furthermore, the absence of time and space in the unconscious means that the conditions necessary for any process such as instinct are similarly absent. Matte Blanco demonstrates the way in which the antinomies that he explores can be explained in terms of the logics that obtain in the unconscious, and he suggests that the concept of the death instinct is one of the most profound expressions of the relationship between the modes that underlie conscious and unconscious logic. 相似文献

我国3~6岁儿童个性类型及发展特点的研究 总被引:2,自引:0,他引:2
该文在以往中国儿童个性结构研究基础上,以问卷调查(n=927)方式,将层次聚类和迭代聚类两种方法结合起来,同时采用理论分析等方法最终确定我国3~6岁儿童的个性类型包括认可型、矛盾型、拒绝型及中间型四类。其中认可型属于积极个性类型,矛盾型和拒绝型属于消极个性类型。研究表明,中班到大班阶段是幼儿个性发展相对重要的时期。男女幼儿在多个个性维度及大部分具体特质方面存在着明显的性别差异。 相似文献

儿童青少年的创造性人格发展特点的研究 总被引:9,自引:0,他引:9
本研究以《威廉姆斯创造性个性倾向测验》为测验工具、以3729名(9~19岁)学生为研究对象,考察了儿童青少年的创造性人格发展的特点及影响因素。研究发现:儿童青少年创造性人格的发展存在阶段性;单亲家庭与双亲家庭的学生在创造性人格水平上没有差异;女生在创造性人格的总水平以及冒险性、想象力维度的得分显著高于男生;不同类型学校学生的创造性人格水平在各个学段都存在差异,并存在不同的发展趋势,其中重点学校学生创造性人格的变化方向是向下的,其显著的下降发生在初高中之间。 相似文献
