Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise.  相似文献

数学教学中的开放式教学——创造一种课堂数学文化   总被引:5,自引:4,他引:5  
数学教学中需要对开放式教学进行合作研究。在日本的开放式教学中,数学问题被选择是用来说明一个问题的多种解法或多个正确答案。数学教学要实现一种全新的课堂数学文化,这种数学形式的特点是:问题开放、解决问题的过程开放、构建问题开放、评价开放,使学生能自由地思考,发展学生的思维能力。  相似文献

Lapides, J. “Teaching styles in adult education. An exploratory essay,” Revue ATEE Journal 3 (1980) 191‐205.

Two approaches to teaching styles are explored. The first is a static approach borrowed from management research and organizational development practice. In this approach teaching styles were derived from Maslow's hierarchy of needs. They were seen as the interpersonal styles of behavior with others, which grow out of people's needs. Seven teaching styles were identified and described. The second approach, in contrast with the life‐style approach, is based on the assumption that teachers can be trained in alternative styles. Mosston believes that everyone can change through learning and that teaching style is a learned characteristic. Seven styles from command to discovery have been identified and described. Suggestions for teacher training are included.  相似文献

This paper focuses on seven major managerial practices and three negative conditions that must be managed to enhance employee growth and development. These managerial practices and conditions have significant potential for human resource development practitioners and performance improvement technologists by providing new perspectives to improve employee performance through employee growth and development activities. Surveys measuring employee perceptions of manager behaviors were administered to 503 MBA and PhD students from the United States, resulting in 463 useable responses. The hypotheses were tested using linear regression and structural equation modeling. Based on the analysis, the researchers found that involving employees in decision making, motivating employees, treating employees as unique individuals, and making certain that managers are effective have the highest influence on employee growth and development.  相似文献

The concepts of having fun and being aware of feeling states are presented as two critical factors in ski racing. First, the positive motivational characteristics of ‘fun’ are outlined. It is suggested that fun is not only a concept for young athletes but elite ones as well. Preliminary data based on a questionnaire, completed by the United States Alpine Ski Team and approximately 150 ski coaches, are presented. Second, the discussion on feelings refers to the mental programming of tactile sensations and determining one's emotional arousal (feeling state) prior to, and during, competition. Practical suggestions are made with regard to the psychological states and their effects on ski racing.  相似文献
