AbstractThis study compared the use of sand and grass training surfaces throughout an 8-week conditioning programme in well-trained female team sport athletes (n = 24). Performance testing was conducted pre- and post-training and included measures of leg strength and balance, vertical jump, agility, 20 m speed, repeat speed (8 × 20 m every 20 s), as well as running economy and maximal oxygen consumption (VO2max). Heart rate (HR), training load (rating of perceived exertion (RPE) × duration), movement patterns and perceptual measures were monitored throughout each training session. Participants completed 2 × 1 h conditioning sessions per week on sand (SAND) or grass (GRASS) surfaces, incorporating interval training, sprint and agility drills, and small-sided games. Results showed a significantly higher (P < 0.05) HR and training load in the SAND versus GRASS group throughout each week of training, plus some moderate effect sizes to suggest lower perceptual ratings of soreness and fatigue on SAND. Significantly greater (P < 0.05) improvements in VO2max were measured for SAND compared to GRASS. These results suggest that substituting sand for grass training surfaces throughout an 8-week conditioning programme can significantly increase the relative exercise intensity and training load, subsequently leading to superior improvements in aerobic fitness. 相似文献

I should like to talk to you about a matter which was a great concern to Ruth Wong, as it is to me – the question of what ‘education’, in the brod sense, can or should do to alleviate the plight of the many millions of the world's children, who, for one reason or another, are unlikely to live full, healthy, productive and happy lives as their more fortunate fellows. ‘Disadvantage’ has been interpreted in many ways. Indeed, each of us has his or her own concept of what constitutes the term, just as each of us has personal ideas about ways of eliminating or minimizing its effects. What I have to say represents my own feelings and opinions. I hope you will forgive me if I begin with some general ideas, one or two of which may seem a little academic, but I think it is important to be clear as a great deal of damage has been done because of confusion of thinking. 相似文献

This article describes a qualitative study of the beliefs and principles of one science teacher. The study employs the Repertory Grid Technique of Kelly (The psychology of personal constructs, New York: Norton, 1955). This technique is illustrated thoroughly by the case study, and ample segments from an interview with the teacher concerned are provided. All relevant information obtained from working with this teacher is used to establish the dominant beliefs held by her. The significance of the study is argued within the framework of curriculum and instructional innovation and implementation. 相似文献

This article establishes a 2-sided media market in which readers have heterogeneous beliefs, media outlets choose their reporting biases, and advertisement prices are determined by bargaining between media outlets and advertisers. The authors have shown that the presence of advertisers strengthens the reporting bias. The bias is increasing in the advertisers' bargaining power and is generally stronger if the advertisers can advertise in multiple outlets. Finally, the authors present an extension of the model on the formation of joint operating agreements for advertising sales among competing newspapers and show that the media bias will be mitigated. 相似文献

Hugh Hartshorne Ph.D.∗ 《Religious education (Chicago, Ill.)》2013,108(3):223-230
The purpose of this column is to keep religious educators abreast of the relevant significant research in the general field of psychology. Its implications for methods and materials in religious education are clear. Religious educators may well take advantage of every new finding in scientific research. Each abstract or group is preceded by an evaluation and interpretative comment, which aims to guide the reader in understanding the research reported. All of these abstracts are from PSYCHOLOGICAL ABSTRACTS, and used by permission of that periodical. The abstract number is Volume 29, Number 3, June, 1955. 相似文献
