Abstract

Numerous epidemiological investigations have shown that low physical fitness and low physical activity are related to the incidence of coronary artery disease (CAD). Most studies, however, have not examined both variables concurrently to determine which has the strongest association with CAD risk. The purpose of the investigation was to cross-sectionally examine the relationships among physical fitness, physical activity, and risk factors for CAD. Male law enforcement officers (N = 412) from the City of Austin, Texas, were subjects for this study. Physical fitness, physical activity, and risk factors for CAD were assessed through health screenings and from data collected as part of an annual physical fitness assessment. Multivariate analysis of covariance revealed that physical fitness, but not physical activity, was related to several single CAD risk factors. Percent body fat, smoking habits, and Type A behavior score were negatively related to physical fitness level, and high density lipoprotein (HDL) cholesterol was positively related to physical fitness level. Univariate analysis of variance found both physical fitness and physical activity to be significantly related to a composite CAD risk score. Low physical fitness and low physical activity were associated with a high CAD risk score. These data suggest that physical activity must be sufficient to influence physical fitness before statistically significant risk-reducing benefits on single CAD risk factors are obtained, although minimal engagement in weekly vigorous activity provides a significant benefit for the composite CAD risk score. It is plausible, however, that physical fitness is a stronger measure than physical activity and optimally characterizes the relationship among physical activity and CAD risk factors.  相似文献   

An Analysis of the Relationship between Somatotype and Personality Traits of College Women     

Mary Slaughter 《Research quarterly for exercise and sport》2013,84(4):569-575

Abstract

The underlying rationale for the study was based on the conviction that biological factors are important in accounting for human behavior. This study was undertaken to compare the results of selected personality traits with the somatotypes of college women. Somatotypes were determined by the use of somatotype ratings as established by Sheldon. The personality profiles were determined by two personality measuring instruments: (a) the Sixteen Personality Factor Questionnaire, and (b) the California Psychological Inventory. Of the 23 hypotheses which were arbitrarily derived from Sheldon's work on physique and temperament of men, only one proved to be tenable. This tenable hypothesis stated that the component of mesomorphy is significantly correlated with the second order Factor I of the 16 PF (Low Anxiety).  相似文献   

Effect of Guided Practice on Overhand-Throw Ball Velocities of Kindergarten Children     

Lolas E. Halverson  Mary Ann Roberton  M. Joanne Safrit  Thomas W. Roberts 《Research quarterly for exercise and sport》2013,84(2):311-318

Abstract

Forty-five children from two intact kindergartens in one school were randomly assigned by sex to (a) an experimental group which received a movement program that included 120 min of guided practice in the overhand throw; or (b) a control group which received the same movement program but no exposure to the throw. A third group (N = 24), randomly selected by sex from a comparable school, received no movement program. Before and after the eight-week instructional period, ten trials of each child's overhand throw for force were filmed. Horizontal ball velocities were simultaneously recorded. ANOVAs on pre- and posttest ball velocities for each sex within each treatment group revealed no significant practice effect over ten trials (p > .05); thus, the trial mean was used as each subject's score. Two-way ANOVAs (treatment X sex) on the pre- and posttest data indicated no significant velocity differences (p > .05) between groups either before or after instruction. Boys had significantly greater velocities than girls (p < .05). Eight weeks of instruction that included 120 min of guided practice in the overarm throw did not significantly change the ball velocities of kindergarten children when compared to two groups with no formal throwing experience.  相似文献

Number of Reinforcements and Memory Trace for Kinesthetically Monitored Force Reproduction     

Dr. Mary Lou Norrie 《Research quarterly for exercise and sport》2013,84(2):338-342

Abstract

The effect of the number of reinforcements on the memory trace for a kinesthetically monitored force reproduction task was studied. Sixty college women were divided by a balanced order into three groups of 20 each. One group had one reinforcement, one had five reinforcements, and the third had nine reinforcements. The reproduction attempt was either immediate or after a 30-sec. delay. Analysis of variance for constant error indicated that multiple reinforcements improved the accuracy of performance for immediate reproduction but that the improvement was not retained over a retention interval of 30 sec. The tendency to overshoot the standard occurred for both the immediate and delayed reproduction conditions.  相似文献   

Student attitudes towards and use of ICT in course study,work and social activity: A technology acceptance model approach     

Rob Edmunds  Mary Thorpe  Grainne Conole 《British journal of educational technology : journal of the Council for Educational Technology》2012,43(1):71-84

The increasing use of information and communication technology (ICT) in higher education has been explored largely in relation to student experience of coursework and university life. Students' lives and experience beyond the university have been largely unexplored. Research into student experience of ICT used a validated model—the technology acceptance model—to explore the influence of work and social/leisure contexts as well as course study, on attitudes towards and take up of technology. The results suggest that usefulness and ease of use are key dimensions of students' attitudes towards technology in all three contexts but that ICT is perceived most positively in the context of work and technology use at work is an important driver for technology use in other areas.  相似文献   

How inconvenient assumptions affect preservice teachers’ uptake of new interactional patterns in mathematics: analysis and aspiration through a bifocal lens     

Mary Klein 《Educational Studies in Mathematics》2012,80(1-2):25-40

In this paper, I highlight the inadequacies of contemporary theoretical and philosophical orthodoxies to fully address pedagogic change. The required change is in mathematics education, and it has to do with enabling preservice teachers, upon graduation, to rework extant power relations in implementing new interactional patterns that centre the mathematics and the learner in dynamic, productive interaction. I interpret data from published research and my own teaching using psychological, overlaid with poststructuralist, constructs of the relationship between knowledge and action. In data interpretation I read through the words for a psychological interpretation (meaning), and I look at the words for poststructuralist indications of subjectification and identity formation (related to how well students recognise themselves as full participants in the combined discourses of mathematics and education). I have my cake and eat it; contradictory notions of the learner and learning to teach in innovative ways are held together to demonstrate (a) how it can happen that a teacher educator’s aspirations can be held ransom to constituted assumptions that inconveniently work against change, and (b) how the recognition that humanist assumptions, mathematical proficiency and agency are discursively constituted (Davies, 1990) can suggest avenues for change in teacher education.  相似文献

From the contribution to the action approach: White teachers' experiences influencing the development of multicultural science curricula     

Regina L. Suriel  Mary M. Atwater 《科学教学研究杂志》2012,49(10):1271-1295

In this exploratory case study, we sought to understand teacher's integration of multicultural curricula in science curriculum units, and how personal experiences influenced the level of integration in light of Bank's typology of ethnic content integration into school curricula. Five research participants volunteered and were selected so as to be representative of the demographic of pre‐service and in‐service teachers in the southern United States. The aim was to explore teachers' personal experiences with cultural others that either facilitated or impeded their adoption of multicultural curricula strategies in science curricula units. Case narratives present and discuss interview data and assigned curricula projects. Findings suggest that participants who had transformative cultural experiences and who identified as the marginalized cultural other, transformed science curricula at higher levels of Bank's typology for curricula' multicultural approaches. © 2012 Wiley Periodicals, Inc.

Growing confidence in educational research: Threats and opportunities     

Mary James 《British Educational Research Journal》2012,38(2):181-201

We live in difficult times—socially, economically and politically—and it is right that learned societies, such as the British Educational Research Association, reflect on their purpose and direction. We cannot take for granted the social contract that supports the funding of social science and educational research. This paper reflects on enduring themes and new pressures and argues for special attention to: collaboration within and beyond the community of university‐based educational researchers; support for, and recognition of, the importance of reviews of research; the development of accessible forms of communication of findings and their implications, to guide sound decision making; more direct engagement with practitioners, policy makers and the public. It argues that it is time for communities of educational researchers to have confidence to become outward looking and strengthen alliances with other groups of researchers at home and abroad, across disciplines, with different types of research institutions and also with practitioners and policy makers. What drives this should be our principal aim to pursue educational research and its application for the improvement of education and the public benefit.  相似文献
