The effect of periodized resistance training on accelerative sprint performance     

Moir G  Sanders R  Button C  Glaister M 《Sports biomechanics / International Society of Biomechanics in Sports》2007,6(3):285-300

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6-10%). However, both groups increased 0-10 m sprint times (experimental group = 6%; control group = 3%) while 10-20m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0-10m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training.  相似文献   

Differential effects of norm-referenced and self-referenced feedback on performance expectancies,attributions, and motivation     

Wendy McColskey  Mark R. Leary 《Contemporary educational psychology》1985,10(3):275-284

When feedback is provided to students in a norm-referenced manner that compares the individual's performance to that of others, people who perform poorly tend to attribute their failures to lack of ability, expect to perform poorly in the future, and demonstrate decreased motivation on subsequent tasks. The present study examined the hypothesis that the deleterious effects of failure might be attenuated when failure is expressed in self-referenced terms—relative to the individual's known level of ability as assessed by other measures. In this study, subjects received feedback indicating that they did well or poorly on an anagram test, and this feedback was described as either norm-referenced (comparing the individual's performance to that of others) or as self-referenced (comparing performance to other measures of the individual's ability). As predicted, compared to norm-referenced failure, self referenced feedback resulted in higher expectancies regarding future performance and increased attributions to effort. Contrary to expectations, attributions to ability were not affected. The implications of the results for the structure of academic feedback are discussed.  相似文献   

Helping the “Non-Law” Librarian Understand Law Library Requirements for Interlibrary Loan Copy Requests     

David Mark Zopfi-Jordan 《Journal of Interlibrary Loan, Document Delivery & Electronic Reserve》2013,23(2):111-118

Law library interlibrary loan departments must work under the constraints of The Bluebook Uniform System of Citation when requesting materials for cite checkers. This article discusses the issues that arise during the interlibrary loan process for requesting sources cited in legal articles.  相似文献   

Attributions in a mastery instructional system: Is an emphasis on effort harmful?     

Mark Grabe 《Contemporary educational psychology》1985,10(2):113-126

Self-worth theorists have claimed that students of lower ability may reduce effort in likely failure situations to avoid the attribution of poor performance to their own incompetence. The likely success of mastery learning, an instructional technique stressing student persistence, has been questioned because of this phenomenon. Several studies which examined the hypothesized relationship between achievement, effort, and perceived ability within a mastery context were conducted. In none of the studies did it appear that students reduced effort because of the threat of failure or that expending effort led to lower estimates of ability. In fact, students expending effort rated their ability as having a more positive influence on performance than less persistent students. It is argued that mastery learning, like some achievement change programs, encourages students to attribute their performance to their level of effort.  相似文献

Optimized versus corrected peak power during friction-braked cycle ergometry in males and females     

James DV  Wood DM  Maberly TC  De Ste Croix M 《Journal of sports sciences》2007,25(8):859-867

The aim of this study was to compare optimization and correction procedures for the determination of peak power output during friction-loaded cycle ergometry. Ten male and 10 female sports students each performed five 10-s sprints from a stationary start on a Monark 864 basket-loaded ergometer. Resistive loads of 5.0, 6.5, 8.0, 9.5, and 11.0% body weight were administered in a counterbalanced order, with a recovery period of 10 min between sprints. Peak power was greater and occurred earlier, with less work having been done before the attainment of peak power, when the data were corrected to account for the inertial and frictional characteristics of the ergometer. Corrected peak power was independent of resistive load (P > 0.05), whereas uncorrected peak power varied as a quadratic function of load (P < 0.001). For males and females, optimized peak power (971 +/- 122 and 668 +/- 37 W) was lower (P < 0.01) than either the highest (1074 +/- 111 and 754 +/- 56 W respectively) or the mean (1007 +/- 125 and 701 +/- 45 W respectively) of the five values for corrected peak power. Optimized and mean corrected peak power were highly correlated both in males (r = 0.97, P < 0.001) and females (r = 0.96, P < 0.001). The difference between optimized and mean corrected peak power was 37 +/- 30 W in males and 33 +/- 14 W in females, of which approximately 15 W was due to the correction for frictional losses. We conclude that corrected peak power is independent of resistive load in males and females.  相似文献   

Survey on Teaching Contemporary British Fiction   总被引：1，自引：1，他引：0  

Philip Tew  Mark Addis 《Changing English: An International Journal of English Teaching》2007,14(3):313-324

The teaching of contemporary British fiction in English departments in the United Kingdom is reviewed. The study primarily focuses upon evaluative engagement with current teaching. The literary and theoretical texts taught on courses are considered, as are the use and availability of different kinds of supplementary literary‐critical materials. Data collection was through semi‐structured interviews and a survey of online material. The periodisation and focus of general contemporary British fiction teaching is emerging from a more diffuse field where postmodern, gendered and post‐colonial readings still tend to shape courses and modules. A new post‐1970s idea of the contemporary is rapidly emerging.  相似文献
