The purpose of this study was to investigate the differences of knee concentric and eccentric strength and impact related knee biomechanics between jumpers and non-jumpers during step-off landing tasks. Ten male college swimming athletes (non-jumpers) and 10 track and volleyball athletes (jumpers) were recruited to participate in two test sessions: a muscle strength testing session of concentric and eccentric extension for dominant knee joint at 60 °/s and 180 °/s and a landing testing session. The participants performed five trials of step-off landing in each of four conditions: soft and stiff landing from 0.4 m and 0.6 m landing heights. The three-dimensional kinematics and ground reaction force were recorded simultaneously during step-off landing conditions. The results showed that the jumpers had significantly greater peak knee eccentric extension and concentric flexion torques compared to the non-jumpers. No significant group effects were found for peak vertical ground reaction force and knee range of motion during landing. The jumpers had significantly greater knee contact flexion angle, maximum knee flexion angle and initial knee extension moment compared to the non-jumpers. These results suggest that these athletes adopted a favorable impact attenuation strategy that is related to the greater knee eccentric muscle strength and training. 相似文献

Having language delay—one of the common neurodevelopmental difficulties during childhood—does not only imply an impairment in communication in the 1st few years of life. Previous studies have suggested that language problems have long-term implications for social, emotional, and intellectual development. Researchers have found that early identification and intervention of speech and language delay yields better treatment effects. However, unlike most of the motor developmental assessment tools, language assessment tools are not readily transferred across cultures because of the different linguistic features and the developmental stages of such features in a particular language or dialect. The present study presents an empirical example of the initial development of a culturally sensitive screening protocol, using vocabulary size as the indicator to minimize the effect of linguistic differences. 相似文献

The theory of planned behavior has been applied to sports and exercise behaviors. According to this theory, human intention to take action in a specific context is guided by three antecedents: attitude, subjective norm, and perceived behavioral control. Behavioral intention mediates the relationships between these three considerations and its ultimate performance. However, this theory has seldom been applied to the behaviors of spectators of sporting events. A sample of 269 volleyball spectators in Taiwan was studied to examine whether people's intention mediated their attitudes, subjective norms, and perceived behavioral control toward a given behavior, watching the 2010 Fédération Internationale de Volleyball World Grand Prix in Taipei. Regression analyses did not support behavioral intention as a mediator. This result is discussed in the context of planned behavior. 相似文献

The main purpose of this study is to investigate whether applicants' impression management (IM) tactics indirectly influence hiring recommendations through cognitive mechanisms (i.e. recruiters' perceptions of person–organisation [P–O] fit, person–job [P–J] fit, and person–recruiter [P–R] fit) or affective mechanisms (i.e. recruiters' positive mood) during authentic employment interviews for actual job openings. Participants consisted of 221 applicant–recruiter dyads from 50 companies in Taiwan. The results demonstrated that applicants' self‐focused IM tactics are positively related to recruiter perceptions of P–J fit, which in turn influence hiring recommendations. In addition, applicant other‐focused IM tactics affect hiring recommendations through recruiters' perceptions of P–O fit. Moreover, applicants' non‐verbal IM tactics were positively related to recruiters' positive mood, which in turn affected recruiters' perceptions of P–J fit and P–O fit, thereby affecting hiring recommendations. 相似文献

University students were trained to discriminate between two gray-scale images of faces that varied along a continuum from a unique face to an average face created by morphing. Following training, participants were tested without feedback for their ability to recognize the positive face (S+) within a range of faces along the continuum. In Experiments 1 and 4, the range of stimuli presented during testing was manipulated. In Experiment 2, participants viewed different ranges of faces during an adaptation period that followed training and preceded testing. In all experiments, generalization functions revealed peak shifts or area shifts (fewer “yes” responses to novel faces on the negative side of the S+), but no systematic effects of the test or adaptation range. Peak shift was found both for upright and inverted faces and occurred even if the orientation of the face was reversed between training and test. Using similar methods, either an area shift or range effect (but not both together) was demonstrated for line tilt stimuli (Experiment 3), and the appearance of these effects depended on instructions. It appears that peak shift and area shift are robust across many different kinds of stimuli, but range effects may not readily occur with complex multidimensional stimuli. 相似文献

本文以朱震所列周敦颐<太极图>"动阳"二字的标注为突破口,对比杨甲<六经图>、<道藏·周易图>所列及朱熹改造等诸流变图,结合周敦颐<太极图易说>及<易通>的文字叙述,考证了周敦颐<太极图>的原貌.笔者认为,对<周氏太极图>的考辨,应从其"流变"人手,进而求得其图之原貌,然后方可进入考证其图之来源.文中指出:周敦颐以太极为一气,主太极有动静而生阳生阴之说,而朱熹则以太极为一理,而"理不会自动静",动静只是阴阳自身之动静,出于建立其理学系统的需要,便有意对杨甲所列<周氏太极图>进行了改造.于是,通过比较二人太极观之不同,便可从中分辨<太极图>原图与改造图之间的差别,从而分析其二人各自的理学思想. 相似文献

论道教的"存想"与艺术创作中的"审美想象"之异同 总被引:1,自引:0,他引:1
道教修炼中的"存想"与艺术创作中的"审美想象"作为想象的两种类型,二者存在着较大的区别,也存在着一些相通、相似之处.本文就两种想象所要实现的目的、想象的方式、想象的内容、想象产生的源泉、想象给主体带来的自由等等方面的不同加以比较.同时指出两者存在的一些相似之处,认为"存想"具有着"审美想象"的因子,二者都伴随着强烈的情感体验. 相似文献

Bowenian theory and MRI family therapy model were chosen to treat a Korean male adult client whose symptomatic problems were bullying and game addiction. To test its validity of therapeutic effectiveness, the following case analysis methods were used: narrative analysis of interview contents, categorization of the nine sessions of verbatim, videotaping, and notes according to classified concepts (i.e., triangulation), and explanation using matrix and network. Results showed that low level of differentiation, patterns of emotional cutoff, and dynamics of triangulation were clearly present in this client. After MRI family therapy, changes were evident in perceptive references, communication patterns, stress-coping mechanism, symptomatic behaviors, and intra-family relationships. 相似文献
