The purpose of the present study was to examine the factorial and convergent validity of the German translation of the Exercise Identity Scale (EIS; Anderson & Cychosz, 1994). We introduce a bifactor model as a possible alternative to the previously discussed one- and two-factor models. Using an online study with 530 participants, our results suggest that the EIS should be considered a unidimensional measure. For this one-factor model, temporal invariance (time interval: 2 weeks) and invariance between men and women could be established. Relations to similar constructs were in the expected directions. We provide a psychometrically sound German version of the EIS, which demonstrated factorial and convergent validity in this study. The use of the scale in German samples is likely to advance research on exercise adoption and maintenance by integrating the exercise identity construct. 相似文献

We investigated the associations of cardiometabolic risk factors with academic achievement and whether motor performance, cardiorespiratory fitness, physical activity, or sedentary behaviour mediated these associations. Altogether 175 children 6–8 years-of-age participated in the study. We assessed body fat percentage (BF%), waist circumference, insulin, glucose, triglycerides, HDL cholesterol, and systolic and diastolic blood pressure, leptin, alanine aminotransferase, and gamma-glutamyltransferase (GGT). Reading fluency, reading comprehension, and arithmetic skills were assessed using standardized tests. Speed/agility, balance, and manual dexterity test results were used to calculate motor performance score and physical activity was assessed by combined heart rate and movement sensor and cardiorespiratory fitness by maximal cycle ergometer test. In boys, BF% was inversely associated with reading fluency (β = ?0.262, P = 0.007) and reading comprehension (β = ?0.216, P = 0.025). Motor performance mediated these associations. Leptin was inversely related to reading fluency (β = ?0.272, P = 0.006) and reading comprehension (β = ?0.287, P = 0.003). The inverse association of leptin with reading fluency was mediated by motor performance. In girls, GGT was inversely associated with reading fluency independent of confounders (β = ?0.325, P = 0.007). The inverse association of BF% with academic achievement among boys was largely explained by motor performance. Leptin in boys and GGT in girls were inversely associated with academic achievement independent of confounding factors. 相似文献

While much research has been done to analyze whether socioeconomic status influences prosocial behavior in the form of donations, no consensus has yet emerged in the relevant literature. We contribute to this research by studying, based on a dataset from a questionnaire of volunteers of sports clubs in Palatinate (part of Rhineland–Palatinate, Germany) whether social status affects donations. We measured social status of volunteers of sports clubs along the dimensions income, vocation, education and we considered status crystallization. Results showed that social status has a positive effect on the likelihood of donations. We report similarities and differences across different categories of donations (donations to one’s own sports club, to other clubs, to aid projects, and political parties). 相似文献

This study examines the relationships between the environmental attitudes and environmental knowledge of schoolchildren within the framework of an environmental intervention. We employed questions from the 2-MEV model to monitor students’ environmental attitudes in terms of the model factors Preservation and Utilisation while concurrently monitoring three environmental knowledge dimensions (system, action-related and effectiveness knowledge) at three different test times during the course of a four-day field centre programme for fourth-graders (N = 133, Mage = 9.8 years). Probably due to measurement constraints (e.g. a ceiling effect, social desirability), we found no correlation between environmental knowledge and the attitude Preservation at all test times. The attitude Utilisation correlated negatively with all environmental knowledge dimensions, indicating that students who score higher on Utilisation are more likely, for example, to have and gain more system knowledge through programme participation than the other students or vice versa, as a causal relationship cannot be derived from our analyses: system knowledge may also influence Utilisation. In other words, children who refrain from (ab)using nature also seem to put more effort into improving their environmental knowledge and/or children who engage in learning about the environment will become less exploitative towards the environment. 相似文献

The aim of this paper is to deepen our understanding of the inherent purpose of sports competitions. In ‘On Winning and Athletic Superiority’, Nicholas Dixon states that the central comparative purpose of an athletic contest is to determine which team or player is superior, or, synonymously, to provide an accurate measure of athletic superiority. Dixon identifies athletic skill as the standard of athletic superiority in competitive sport. However, I argue there are three separate standards of athletic superiority: the demonstration of athletic skill, the achievement of prelusory goal using lusory means, and achievement of superior formal result. This stance responds to Dixon’s argument that failed athletic contests are contests that have not fulfilled the central purpose of competitive sport, because they have been undermined by refereeing errors, cheating, gamesmanship or bad luck. I argue that a failed athletic contest occurs when any of the three standards of athletic superiority conflict. 相似文献

Abstract The relative effectiveness of six intensive training programs on the development of four selected skills was studied, with emphasis on limited time encountered within the semester organizational plan. One hundred and twenty college freshmen men volunteers were randomly assigned to training groups of 30 members each, which met for two sessions a week for 16 weeks. Results indicated that: (a) direct practice jumping, alone or combined with repetitive sprinting or weight training, was significantly superior to weight training alone on standing broad jump development; (b) direct practice of a zigzag run was superior to both weight training and repetitive sprinting; and (c) when group acquisition of “adequate” skill is the objective, performance improvements educed over the first nine weeks were great enough to question the merits of persisting at an activity over a full semester. Only the zigzag run was adversely affected by the spring vacation cessation of training. 相似文献

To assess the role of qualitative knowledge of results (KR) in children's motor learning, four-year-old subjects performed a linear positioning task. Children were divided into three groups, each varying on KR precision. A significant reduction in variable error (p < .05) over trials seemed to indicate that children can utilize KR to become more consistent in learning. No significant differences were found among the three KR groups; however, the most precise KR condition tended to show fewer errors than the least precise KR condition. Some recommendations for future research are discussed. 相似文献

Abstract The present study was designed to examine physiological responses during motocross riding. Nine Finnish A-level motocross riders performed a 15-min ride at a motocross track and a test of maximal oxygen uptake ([Vdot]O2max) in the laboratory. Cardiopulmonary strain was measured continuously during the ride as well as in the [Vdot]O2max test. During the ride, mean [Vdot]O2 was 32 ml · kg?1 · min?1 (s = 4), which was 71% (s = 12) of maximum, while ventilation (V E) was 73% (s = 15) of its maximum. The relative [Vdot]O2 and V E values during the riding correlated with successful riding performance (r = 0.80, P < 0.01 and r = 0.79, P < 0.01, respectively). Mean heart rate was maintained at 95% (s = 7) of its maximum. Mean blood lactate concentration was 5.0 mmol · l?1 (s = 2.0) after the ride. A reduction of 16% (P < 0.001) in maximal isometric handgrip force was observed. In conclusion, motocross causes riders great physical stress. Both aerobic and anaerobic metabolism is required for the isometric and dynamic muscle actions experienced during a ride. 相似文献

This article examines to what extent the Nordic countries, which have been characterized as the world's leading information societies, show similar patterns of Internet use. The data consists of the Danish, Swedish, Norwegian, and Finnish sections of the European Social Survey 2002 ( n = 7539) and 2004 ( n = 7211). The similarities and differences in the Internet use are analyzed using sociodemographic and economic information. Temporal changes in the distribution of use between population groups and between countries are also examined. The findings indicate that there are clear disparities in the Internet use patterns, which have not evened out in the early 21st century. 相似文献
