Understanding the effects of training in different footwear on sporting performance would be useful to coaches and athletes. Purpose: This study compared the effects of computerized agility training using 3 types of footwear on change-of-direction and balance performance in young adults. Method: Thirty recreationally active young adults (Mage = 22.8 ± 3.1 years; Mheight = 1.71 ± 0.7 m; Mbodymass = 73.4 ± 10.3 kg) were randomly assigned to a 6-week computerized agility training intervention in 1 of 3 footwear groups (n = 10/group): barefoot, minimal footwear, or traditional shoes. Participants had no previous barefoot or minimal-footwear training experience. Dependent variables included change-of-direction test time to completion, Star Excursion Balance Test, and single-leg stability evaluation. Testing was performed at the start of the training program, after 2 weeks, after 4 weeks, and at the end of the training program. Results: No group or time interactions were found for any of the dependent variables. Time main effects were observed for the performance measures of change of direction, Star Excursion, and single-leg-with-eyes-open stability evaluation. Participants improved in all 3 tests as early as 2 weeks into the intervention, with improvements continuing through the entire 6-week intervention. Conclusions: The lack of interaction and footwear effects suggests that agility and balance improvements during foot agility training are independent of footwear in a recreationally active young-adult population. Computerized agility training improves change-of-direction and balance performance within 2 weeks of training implementation. Future studies should consider footwear training effects in different populations, including frail older adults and athletes.  相似文献

Maintaining that academic freedom is necessary if schools are to function effectively, Dr. Dahl presents lucid arguments to support his position.  相似文献

This study was part of a larger project directed by C. E. Osgood and J. C. Nunally of the University of Illinois, conducted under a grant from the National Institute of Mental Health. It is especially interesting, not only because of the current controversy over television program control, but for the light it throws on the operation of the network departments charged with the censorship function.  相似文献

All universities in Australia are asked to develop various attributes in their degrees. From 2011, the Australian Qualifications Framework has stipulated some of these attributes for the various levels of qualifications. There are many challenges that face assuring the development of graduate attributes in a Bachelor of Arts as the degree typically has very few core units (if any), a wide choice of subjects, a limited prerequisite structure and, unlike many professional degrees, the BA does not have an external accrediting body. This paper describes an approach used to identify the pathway undertaken by each individual student in a History major of the Bachelor of Arts. This pathway was used to identify the graduate attributes that each student should have developed, as articulated by the lecturers. Student perceptions were then compared with the graduate attributes that were intended to be developed through each individual's combination of units studied. In summary, through analysing the two methods (student perceptions and unit pathway) we found that they concurred with respect to only three-quarters of the graduate attributes. Possible reasons for the discrepancies and future research are discussed. The need for multiple methods of providing evidence of the development of graduate attributes is confirmed.  相似文献

Through a qualitative interview design, this study investigated how participation in a rigorous academic environment may influence gifted students who demonstrate high levels of perfectionism. The study also examined how their responses to a rigorous academic and residential environment may differ according to the type of perfectionism. Findings indicated that some socially prescribed perfectionists reported an increase in perfectionism, whereas some self-oriented perfectionists reported an increase followed by a decrease in their perfectionism. Overall, the majority of the participants, regardless of their type of perfectionism, indicated a decrease in their perfectionism as a result of their new academic environment. Reactions to experiencing imperfections ranged from calm to guilt or even anger, depending on the type of perfectionism. Implications for working with gifted students who show high levels of perfectionism are discussed.  相似文献
