Different durations within the method of best practice affect the parameters of the speed–duration relationship

The aim of the study was to determine whether estimates of the speed–duration relationship are affected using different time-trial (TT) field-based testing protocols, where exhaustive times were located within the generally recommended durations of 2–15?min. Ten triathletes (mean?±?SD age: 31.0?±?5.7?years; height: 1.81?±?0.05?m; body mass: 76.5?±?6.8?kg) performed two randomly assigned field tests to determine critical speed (CS) and the total distance covered above CS (D?). CS and D? were obtained using two different protocols comprising three TT that were interspersed by 60?min passive rest. The TTs were 12, 7, and 3?min in Protocol I and 10, 5, and 2?min in Protocol II. A linear relationship of speed vs. the inverse of time (s?=?D??×?1/t?+?CS) was used to determine parameter estimates. Significant differences were found for CS (p?=?0.026), but not for D? (p?=?0.123). The effect size for CS (d?=?0.305) was considered small, while that for D? was considered moderate (d?=?0.742). CS was significantly correlated between protocols (r?=?0.934; p?D? (r?=?0.053; p?=?0.884). The 95% limits of agreement were ±0.28m?s^?1 and ±73.9?m for CS and D?, respectively. These findings demonstrate that the choice of exhaustive times within commonly accepted durations results in different estimates of CS and D?, and thus protocols cannot be used interchangeably. The use of a consistent protocol is therefore recommended, when investigating or monitoring the speed–duration relationship estimates in well-trained athletes.  相似文献

Word Spotting in Bitmapped Fax Documents     

William J. Williams  Eugene J. Zalubas  Alfred O. Hero III 《Information Retrieval》2000,2(2-3):207-226

Images and signals may be represented by forms invariant to time shifts, spatial shifts, frequency shifts, and scale changes. Advances in time-frequency analysis and scale transform techniques have made this possible. However, factors such as noise contamination and style differences complicate this. An example is found in text, where letters and words may vary in size and position. Examples of complicating variations include the font used, corruption during facsimile (fax) transmission, and printer characteristics. The solution advanced in this paper is to cast the desired invariants into separate subspaces for each extraneous factor or group of factors. The first goal is to have minimal overlap between these subspaces and the second goal is to be able to identify each subspace accurately. Concepts borrowed from high-resolution spectral analysis, but adapted uniquely to this problem have been found to be useful in this context. Once the pertinent subspace is identified, the recognition of a particular invariant form within this subspace is relatively simple using well-known singular value decomposition (SVD) techniques. The basic elements of the approach can be applied to a variety of pattern recognition problems. The specific application covered in this paper is word spotting in bitmapped fax documents.  相似文献   

Critical Race Theory and the Transfer Function: Introducing a Transfer Receptive Culture     

Dimpal Jain  Alfred Herrera  Santiago Bernal  Daniel Solorzano 《Community College Journal of Research & Practice》2013,37(3):252-266

In California, the majority of students of color who enter postsecondary education do so in the community colleges. However large numbers of them leave and do not transfer to four-year institutions; in particular to highly selective public four-year colleges and universities. By using the theoretical perspective of critical race theory, transfer can be seen as a dual commitment between both the sending and receiving institution as we put forth the conceptual framework of a “transfer receptive culture.” We define a transfer receptive culture as an institutional commitment by a four-year college or university to provide the support needed for students to transfer successfully—that is, to navigate the community college, take the appropriate coursework, apply, enroll, and successfully earn a baccalaureate degree in a timely manner. We outline five elements, informed by critical race theory, that are necessary to establish a transfer receptive culture and outline specific strategies within each element that practioners can employ on their home campuses.  相似文献   

Validity of the ActiGraph GT1M during walking and cycling     

Bjorge Herman Hansen  Ingvild Børtnes  Maria Hildebrand  Ingar Holme  Elin Kolle  Sigmund Alfred Anderssen 《Journal of sports sciences》2013,31(6):510-516

Abstract

The ActiGraph activity monitors have developed and newer versions of the ActiGraph accelerometers (GT1M, GT3X and GT3X +) are now available, including changes in hardware and software compared to the old version (AM7164). This is problematic as most of the validation and calibration work includes the AM7164. The aims of the study were to validate the ActiGraph GT1M during level and graded walking and to assess the potential underestimation of physical activity during cycling. Data were obtained from 20 participants during treadmill walking and ergometer cycling. Energy expenditure was measured via indirect calorimetry and used as the criterion method. Activity counts were highly correlated with energy expenditure during level walking (R² = 0.82) and graded walking at 5% and 8% (R² = 0.82 and R² = 0.67, respectively). There was no linear relationship between activity counts and energy expenditure during cycling. The average activity counts for all data points during cycling was 1,157 counts per minute (CPM) (SD = 974), and mean energy expenditure was 5.0 metabolic equivalents. The GT1M is a valid tool for assessing walking across a wide range of speeds and gradients. However, there is no relationship between activity counts and energy expenditure during cycling and physical activity is underestimated by ≈73% during cycling compared to walking.  相似文献   

Effects of the Active Smarter Kids (ASK) Physical Activity School-based Intervention on Executive Functions: A Cluster-Randomized Controlled Trial     

Katrine Nyvoll Aadland  Yngvar Ommundsen  Sigmund Alfred Anderssen  Kolbjørn Selvåg Brønnick  Vegard Fusche Moe  Geir Kåre Resaland 《Scandinavian Journal of Educational Research》2019,63(2):214-228

The purpose of this study was to examine the effects of a seven-month curriculum prescribed physical activity (PA) intervention (the Active Smarter Kids [ASK] intervention) on executive functions in 10-year-old Norwegian children. A linear mixed model was used to analyze data from 971–1,123 fifth grade children at 28 intervention schools and 29 control schools. The intervention constituted three PA elements: PA educational lessons, PA breaks, and PA homework, adding 165 minutes of PA to the mandatory 135 minutes of PA and physical education. There was no effect of the intervention on executive functions in the intention-to-treat analyses. Per protocol analyses (n?=?776–850) revealed small effects of the intervention on the composite score of executive functions, cognitive flexibility, and motor skills. Cognitively engaging and coordinative demanding activities/games seem viable options to increase executive functions and possibly improve academic performance in children.  相似文献   

Building and sustaining community in asynchronous learning networks     

Alfred P. Rovai   《The Internet and Higher Education》2000,3(4)

This article applies the concept of classroom community to asynchronous learning networks (ALNs) by taking on the issue of how best to design and implement a course that fosters community among learners who are physically separated from each other. The following factors that can influence sense of community among distant learners are examined: student–instructor ratio, transactional distance, social presence and instructor immediacy, lurking, social equality, collaborative learning, group facilitation, and self-directed learning.  相似文献
