The purpose of this study was to analyse the effect of bike type – the 26-inch-wheel bike (26“ bike) and the 29-inch-wheel bike (29“ bike) – on performance in elite mountain bikers. Ten Swiss National Team athletes (seven males, three females) completed six trials with individual start on a simulated cross-country course with 35 min of active recovery between trials (three trials on a 26“ bike and three trials on a 29“ bike, alternate order, randomised start-bike). The course consisted of two separate sections expected to favour either the 29“ bike (section A) or the 26“ bike (section B). For each trial performance, power output, cadence and heart rate were recorded and athletes’ experiences were documented. Mean overall performance (time: 304 ± 27 s vs. 311 ± 29 s; P < 0.01) and performance in sections A (P < 0.001) and B (P < 0.05) were better when using the 29“ bike. No significant differences were observed for power output, cadence or heart rate. Athletes rated the 29“ bike as better for performance in general, passing obstacles and traction. The 29“ bike supports superior performance for elite mountain bikers, even on sections supposed to favour the 26“ bike. 相似文献

AbstractThis paper examines the confluence of global, regional, and national politics in the lead up to the 1991 Pan-American Games hosted by Cuba. Cuba’s contentious selection as host was wholly underpinned by the international politics of the time. Once selected, the preparations for the Games in Havana were surrounded by an unprecedented domestic economic crisis fueled by shifts in global politics. This paper analyzes how international politics informed the hosting of the 1991 Pan-American Games, and shaped the political challenge the Cuban government faced in hosting such an event. The Revolution’s use of sport domestically and internationally came to the forefront in its efforts as host and the results of those efforts proved to be providential given the emerging political economic contexts during and in the ensuing years after the Games. 相似文献

AbstractIn recent years, there has been a wealth of research into how the game of association football developed. However, rather than establishing a common theme this research has led to competing theories with the debate dividing opinion on how the game of football was developed and propagated. While debate is healthy, the approach taken by some could lead to fellow academics looking to those engaged in sport history as unprofessional. This paper seeks to propose a way forward with academics working towards an all-encompassing history of the sport, by suggesting the adoption of a framework based on the work of Fernand Braudel, where indepth analysis of individual events is combined with the identification of transformational cycles. The paper concludes by suggesting that historians interested in soccer’s early history work together within the framework to develop a more detailed and all-encompassing early history of the sport. This framework will not claim that either the orthodox or revisionist view is accurate, instead it will determine how best to work those debates into an all-encompassing approach while searching for detailed evidence on what was actually occurring at local levels. 相似文献

This paper addresses the adult educator's responsibility to establish an emotionally safe learning environment. Such a climate enables students to address constructively the fears they bring to the learning event. This empowers the learner to risk change-the goal of adult education. The research of Maslow, Rogers, Knowles, and Freire supports an atmosphere of mutual respect as the key to adult learning. Trainers/Teachers of adults were interviewed to identify the kinds of fears that adults bring to the learning event. This paper explores the attitudes and techniques used by the facilitator to create an atmosphere of respect. 相似文献

Multi-domain and longitudinal studies of student achievement routinely find moderate to strong correlations across achievement domains and even stronger within-domain correlations over time. The purpose of this study is to examine the sources of these patterns analysing student achievement in 5 domains across Years 3, 5 and 7. The analysis is of longitudinal population data of over 22,000 students and utilizes fixed-effects models to incorporate stable general and domain-specific latent factors. These latent factors correspond to a general cognitive-ability-like factor and specific aptitudes in particular, or types of, subject areas. The preferred model incorporates both general and domain-specific latent factors with stronger effects for the general factor, although the domain-specific factors are particularly strong for spelling and numeracy. When taking into account general and domain-specific latent factors, the effects of student’s socioeconomic status (SES) and school SES are trivial. 相似文献

This study examines a model of college choice by parents on behalf of their eighth-grade children. A sample of 931 Illinois parents nominated 154 identifiable institutions in a 1986 survey. Multivariate multiple regression is used to predict preferred institutional characteristics, including selectivity, highest degree offering, proximity, enrollment, and tuition. Results indicate that socioeconomic, familial, and college planning characteristics explain 35 percent of the variance in selectivity of colleges in the choice sets, with lesser (but significant) percentages of explained variance for the other institutional characteristics. These parental college nominations parallel previously reported matriculation behaviors. 相似文献

This study examines a pre‐school screening survey battery with an aim to validate it in terms of predicting school performance. Subjects participating in the screening were tested at the end of their first year at school. Analysis of the data, using a canonical correlation procedure, suggested elimination of a number of test items ‐‐ age, sex, age of walking, socio‐economic rating, Draw‐a‐Man Test, balance and posture, body image, perceptual motor match, height and weight. Measures of general ability, visual discrimination, visual reception, general development, receptive language, language concepts and positional concepts were the best predictors of school performance. 相似文献
