Abstract

The aim of this study was to examine the effects of changes in maximal aerobic (MAS) and sprinting (MSS) speeds and the anaerobic reserve (ASR) on repeated-sprint performance. Two hundred and seventy highly-trained soccer players (14.5 ± 1.6 year) completed three times per season (over 5 years) a maximal incremental running test to approach MAS, a 40-m sprint with 10-m splits to assess MSS and a repeated-sprint test (10 × 30-m sprints), where best (RSb) and mean (RSm) sprint times, and percentage of speed decrement (%Dec) were calculated. ASR was calculated as MSS-MAS. While ?RSb were related to ?MSS and ?body mass (r2 = 0.42, 90%CL[0.34;0.49] for the overall multiple regression, n = 334), ?RSm was also correlated with ?MAS and ?sum of 7 skinfolds (r2 = 0.43 [0.35;0.50], n = 334). There was a small and positive association between ?%Dec and ?MAS (r2 = 0.02 [?0.07;0.11], n = 334). Substantial ?MSS and ?MAS had a predictive value of 70 and 55% for ?RSm, respectively. Finally, ?ASR per se was not predictive of ?RSm (Cohen’s = +0.8 to ?0.3 with increased ASR), but the greater magnitude of ?RSm improvement was observed when MSS, MAS and ASR increased together (0.8 vs. +0.4 with ASR increased vs. not, additionally to MSS and MAS). Low-cost field tests aimed at assessing maximal sprinting and aerobic speeds can be used to monitor ?RS performance.  相似文献

Students of Project Adapt (PA), an instructional program for at-risk middle school students in Brooklyn NY, have displayed startling improvement on cognitive outcome measures. Teacher given grades and standardized tests illuminate the progress students have made since entering the program. The current investigation attempts to analyze PA on students' affective responses in a pre/post-test experimental design. Upon entering PA, students completed measures of interest, affect, and their previous teachers' behavior (pre). These ratings were then compared to end of year ratings on the same instruments (post). Results indicate students' perceive PA teachers utilizing different behaviors than their previous teachers. Additionally, student affect and interest increased significantly. Results of this study have implications for both instructional researchers and educational practitioners.  相似文献

This is an extension of an earlier paper by the second author. In the previous work, an algorithm was derived for the moments of an homogeneous equation with noise similar to the white noise, but has small, finite correlation time. In the present work this algorithm is extended for an inhomogeneous equation with the same characteristics. Previous notation has been kept throughout the paper.  相似文献

There is a growing demand for degreed science, technology, engineering and mathematics (STEM) professionals, but the production of degreed STEM students is not keeping pace. Problems exist at every juncture along the pipeline. Too few students choose to major in STEM disciplines. Many of those who do major in STEM drop out or change majors. Females and minorities remain underrepresented in STEM. The success rate of college students who are from low-income background or first-generation students is much lower than that of students who do not face such challenges. Some of those who successfully complete their degree need help in making the transition to the workforce after graduation. A program at Lamar University takes a multidisciplinary approach to addressing these problems. It is designed to recruit, retain and transition undergraduates to careers in STEM, focusing its efforts on five science disciplines and on these “at-risk” students. The program was supported by a 5-year grant from the National Science Foundation and is supported through August 31, 2016 by Lamar University and a grant from ExxonMobil. A formal assessment plan documents the program’s success. The program received an award from the Texas Higher Education Board for its contributions towards Closing the Gaps in Higher Education in Texas. This paper describes the program’s theoretical framework, research questions, methods, evaluation plan, and instruments. It presents an analysis of the results achieved using these methods and implications for improvements to the program resulting from lessons learned.  相似文献

The main focus of this paper is the funding of libraries in Nigeria. The sources of funds for libraries, which include the government, grants, donations and bequests, are discussed. The factors affecting the funding of libraries in Nigeria are highlighted. Finally, alternative sources for funding are also discussed.  相似文献

This study investigated the relationship between people's communication tendencies for sending and receiving verbally aggressive messages with their opinions and feelings about a verbally aggressive television show. Participants (N=216) completed measures of verbal aggressiveness and psychological hurt before viewing a 7‐minute clip from the television show Daddy Dearest. Participants then completed measures for show affinity, character affinity, and show realism. The results showed that people who were verbally aggressive, tended to watch more television weekly, and did not report being hurt by receiving verbally aggressive messages, expressed more affinity for the character and the show and perceived the show to be similar to real life. People who reported greater psychological hurt from receiving verbally aggressive messages and tended to watch more television weekly also reported that the show was similar to real life.  相似文献
