Purpose: The objectives were to develop and validate the Coaches’ Interpersonal Style Questionnaire. The Coaches’ Interpersonal Style Questionnaire analyzes the interpersonal style adopted by coaches when implementing their strategy of supporting or thwarting athletes’ basic psychological needs. Method: In Study 1, an exploratory factor analysis was performed with 265 Spanish male athletes, between 11- and 17-years-old, to confirm the internal structure of the questionnaire. Study 2 was conducted with 430 athletes, also between 11- and 17-years-old. Both confirmatory factor analysis and exploratory structural equation modeling were used to test a set of alternative models to find the best measurement model. Results: The hierarchical exploratory structural equation modeling model showed the best fit to the data and acceptable standardized factor loadings. Concurrent validity was revealed through correlational analysis of the basic psychological need satisfaction and frustration. Conclusion: This study provides a multi-dimensional questionnaire to assess coaches’ interpersonal style perceived by athletes.  相似文献

Abstract

The aim of this study was to compare selected physiological variables and performance markers of soldiers from two “elite” units of the British Army. Ten soldiers from each of the two units were recruited for this study (n = 20). All participants completed three tests while carrying a 20 kg backpack load: (1) a maximal treadmill test using the Bruce protocol; (2) a 2 mile backpack run test specific to Unit A on a consistently flat tarmac road; and (3) a 29 km time-trial over hilly terrain typical of a mountainous area used by Unit B for performance assessment. Heart rate, maximal blood lactate concentration and performance (run time) were assessed during all three tests, with peak oxygen uptake also being measured during the maximal treadmill test. Measurements of anthropometry, isokinetic strength and mental toughness (MT48) were also recorded. There were no significant differences in terms of performance markers between the units (P > 0.05). Performance on the maximal treadmill test correlated with performance on the 2 mile backpack run test (r = ?0.57) and 29 km time-trial (r = ?0.66). Performance on the 2 mile backpack run test in turn correlated with 29 km time-trial performance (r = ?0.77), accounting for 59% of the variance. In conclusion, the maximal treadmill test and the 2 mile backpack run test are useful indicators of performance on the arduous hill march and could be employed in the screening and selection of potential recruits.  相似文献

Abstract

The aim of this study was to determine whether creatine ingested in combination with relatively small quantities of essential amino acids, simple sugars, and protein would stimulate insulin release and augment whole-body creatine retention to the same extent as a large bolus of simple sugars. Seven young, healthy males underwent three randomized, 3-day experimental trials. Each day, 24-h urine collections were made, and on the second day participants received 5 g creatine + water (creatine trial), 5 g creatine + ~95 g dextrose (creatine + carbohydrate) or 5 g creatine + 14 g protein hydrolysate, 7 g leucine, 7 g phenylalanine, and 57 g dextrose (creatine + protein, amino acids, and carbohydrate) via naso-gastric tube at three equally spaced intervals. Blood samples were collected at predetermined intervals after the first and third naso-gastric bolus. After administration of the first and third bolus, serum insulin concentration was increased by 15 min (P < 0.05) in the creatine + carbohydrate and creatine + protein, amino acids, and carbohydrate trials compared with creatine alone, and plasma creatine increased more following creatine alone (15 min, P < 0.05) than in the creatine + carbohydrate and creatine + protein, amino acids, and carbohydrate trials. Urinary creatine excretion was greater with creatine alone (P < 0.05) than with creatine + carbohydrate and creatine + protein, amino acids, and carbohydrate. Administration of creatine + protein, amino acids, and carbohydrate can stimulate insulin release and augment whole-body creatine retention to the same extent as when larger quantities of simple sugars are ingested.  相似文献

The purpose of this study is to resolve ‘moral conflict’ in sport and to present a better approach with respect to right actions for sports participants. While acknowledging that there are many positive values or principles (e.g. Olympism) in sport, some ‘moral conflict’ in sport might still arise and therefore cannot be easily resolved. By introducing Hare's two levels of moral thinking (i.e. intuitive level and critical level), I first clarify the question ‘Why do moral conflicts appear?’ That moral conflicts may arise normally is because people or philosophers tend to think that moral principles ought to be simple and general. In the general situation, it would be fine to follow these kinds of principles when there is no conflicting situation. But in a particular context, there might be a problem. It would be impossible to resolve a conflicting problem if we do not think critically. Second, I suggest that ‘keep the rules’ can be seen as a prima facie principle or duty for sports participants. However, this prima facie principle may not be sufficient or appropriate to resolve the problem of conflict by using the intuitive thinking, since one might face a conflict between ‘keep the rules’ and ‘not to keep the rules’ and s/he cannot select in between. Thus, critical thinking is needed. Third, I try to differentiate critical thinking from intuitive thinking. Critical thinking aims not only to select the best set of prima facie principles for use in intuitive thinking, but also to resolve conflicts between them. So, if we are able to think critically, a prima facie duty sometimes can be overridden by other more important duties (sound and ethical) in a particular situation. However, as not all sports participants are capable enough to think critically, moral education regarding how to develop athletes' ‘critical thinking’ in sport is needed. It may be recommended that virtue ethics play an important role in sport not just through initiating participants into rule‐following but also in cultivating certain dispositions and educating their desires. As it is, what we also need is a good sports education system which can enlighten people toward a better understanding of sport and its values.  相似文献

The wrist is the most frequently injured body region among snowboarders. Studies have shown that the risk of sustaining a wrist injury can be reduced by wearing wrist protection. Currently, there are a wide variety of wrist protection products for snowboarding on the market that offer a range of protective features. However, there are no minimum performance standards for snowboarding wrist protectors worldwide. The International Society for Skiing Safety convened a task force to develop a White Paper to evaluate the importance and necessity of a minimum performance for all wrist protectors used in snowboarding. The White Paper outlines the need for a general framework for a harmonized international standard and reviews the existing evidence. Therefore, this White Paper may serve as a common base for future discussions. The broader goal of developing and implementing such a standard is to reduce the incidence and the severity of wrist injuries in snowboarding without increasing the risk of adverse events, such as upper arm or shoulder injury. The European standard for inline skating wrist protectors (EN 14120) can serve as a starting point for efforts related to a standard for snowboard wrist protectors, but certain modifications to the standard would be required. It is hypothesized that implementation of a snowboarding wrist protector standard would result in fewer and less severe wrist injuries in the sport and could translate into more riding days for healthy snowboarders and significant health-care costs savings.  相似文献

The urban university and urban culture   总被引:1,自引:0,他引:1  
Conclusion We have briefly described an urban university in contrast to the traditional university, and we have recommended several strategies for changing the traditional university. The urban university plays a much more important role in the intellectual life of the urban community. It reaches throughout the community and, in becoming a center of intellectual activity in its urban settings, gives the intellectual life of a community greater focus. We believe that many urban communities would be anxious to develop an urban university and that such communities would be attractive to a great many people.William L. Blizek and Robert B. Simpson are, respectively, Associate Professor of Philosophy and Assistant Professor of Sociology at the University of Nebraska at Omaha.This paper is a revised version of one presented originally at the First National Conference on Urban Education, Kansas City, Missouri, November 25, 1975.  相似文献

A distinct and complex definition of attitude is evolving within the literature. A mental readiness to respond and a correlational consistency between attitude and behavior—although controversial and in need of further study and analysis—remain viable subcomponents within the definition. Most agree that evaluation is the heartbeat of attitude. The impact of social influence on attitudes is becoming increasingly important. Attitudes are learned and not inherited.  相似文献

Concluding Observations From the presentations of the survey outcomes is has become clear that substantial differences exist between both types of institutions as well as between countries. To a large extent, the results for the universities in particular still reflect the dominant notion of professional expertise, especially where the primary processes of teaching and research are concerned. At the same time, it also has become clear that the role of the central institutional administration is a non-negligible factor in higher education, especially for what we can call the ‘non-primary processes’ issues. With respect to differences between countries, the study shows substantial variation between the countries. This alone appears to provide sufficient basis to question the general assumption of the continental model. On the European continent clearly different institutional governance systems exist, and it would appear logical to relate these to the different ways in which national governments in these systems have changed their policies and policy priorities over the years. However, to shed further light on these differences, a more detailed analysis of the data will have to be performed, for example relating the survey out-comes to differences in governmental steering paradigms.  相似文献

This article reflects the results of an investigation involving economics and law students and focusing on the quality and impact of their expertise (or prior knowledge) in relation to the course, Economics and Money. Attention was paid in this project to the construction of different tests intended to grasp the complex nature of prior knowledge at the content level. In relation to the quality of expertise, the results of this project could reveal that economics and law students possess a composite of different expertise components. In relation to the impact of prior knowledge on the acquisition of subject‐oriented knowledge, regression analysis shows that expertise accounts for 16 to 17 percent of the variance in posttest scores. Although this percentage is limited, further analysis could reveal that optimal requisite knowledge and mathematics are important in this perspective. These results are important since they might be helpful in order to guide future initiatives to support students in the initial stages of their studies to cope with the demands of specific domains to be studied. In this study, study time was also used as an independent variable to hypothesize about differences in expertise in the impact on the acquisition of new subject matter. No significant findings could be derived to support hypotheses in this context.  相似文献
