Short-term reliability of inflammatory mediators and response to exercise in the heat

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation.  相似文献

Guideposts and Roadblocks to the Career-Long Scholarly Engagement of Physical Education Teacher Education Faculty     

Catherine P. Berei  Erica Pratt  Melissa Parker  Kevin Shephard  Tanjian Liang  Udon Nampai 《Research quarterly for exercise and sport》2017,88(4):455-467

Purpose: Scholarship is essential for the growth and development of the physical education field. Over time, scholarship expectations have changed, forcing faculty members to alter time spent for research, teaching, and service. Social-cognitive career theory (SCCT) presents a model for understanding performance and persistence in an occupational environment. The interconnected aspects of SCCT have different emphasis related to self-efficacy, outcome expectations, or personal goals pursuit. This study explored physical education teacher education (PETE) faculty members’ continuing engagement in scholarly activity through SCCT. Method: Data collection included interviews with 9 senior PETE faculty members who met the criteria for “productive scholars over time.” Curriculum vitae were collected to verify productivity. Results: Data analysis revealed guidepost themes that included collaborating, finding balance, defining a research process, and maintaining a strong work ethic. Roadblocks encountered included other obligations and lack of support for research. Conclusions: Participants demonstrated strong self-efficacy; held high, positive expectations for success; and set very specific, clear, and deliberate goals. Participant behavior was moderated by their personal attributes (capacity to build relationships, set goals, and maintain interest and passion) and was tempered by the environments in which they worked. Fostering similar behaviors has the potential to guide future and current PETE faculty members in creating supportive and encouraging atmospheres for sustained productivity. The lack of literature relating to this topic warrants the need for more research exploring the influential factors and benefits gained from sustained scholarly productivity over time for PETE faculty members.  相似文献

Children's experiences of fun and enjoyment during a season of sport education     

MacPhail A  Gorely T  Kirk D  Kinchin G 《Research quarterly for exercise and sport》2008,79(3):344-355

This paper reports on a 16-week sport education (SE) unit with just over 70 year 5 students (M age = 10.04 years) in one United Kingdom school during the spring and summer terms and discusses students' SE experiences. Student interviews were conducted throughout the season and a questionnaire on different motivation aspects was administered prior to and before completing the SE season. We report and examine the data in relation to hypothesized influences on fun and enjoyment, including being part of a team, autonomy, and improving game play. The principal reasons SE may be more enjoyable than previous physical education lessons include the greater opportunities for autonomy, affiliation, and competition, plus perceived learning.  相似文献   

The dimensions of reading attitude for children in the intermediate grades     

Ann W. Engin  Fred H. Wallbrown  Dorotha H. Brown 《Psychology in the schools》1976,13(3):309-316

This study represents the first phase of an ongoing research program aimed at identifying the dimensions of reading attitude and determining how these dimensions relate to a broader range of variables such as reading achievement, scholastic aptitude, classroom behavior, and cognitive styles. The 150 items which comprise the experimental edition of A Survey of Reading Altitudes (Wallbrown, Brown, & Engin, 1974) were factor analyzed along with measures of scholastic aptitude, reading vocabulary, and reading comprehension. The analysis was based on the responses of 853 intermediate grade students. The attitude items were presented orally to control for reading problems, but the students also had booklets so they could read the items to themselves. Seven independent dimensions of reading attitude and one reading achievement factor were identified, interpreted, and discussed. The findings are encouraging, since they suggest that investigating the expressed reading attitudes of intermediate grade children constitutes a promising line of educational research.  相似文献   

The impact of an open campus program upon high school students' sense of control over their environment     

Catherine E. Rosen 《Psychology in the schools》1977,14(2):216-219

Students in an experimental and a control high school were compared in the fall and spring on their Locus of Control scores. An Open Campus policy was instituted in the experimental school, which essentially gave its upperclassmen the same freedom and responsibilities as those of a community college student. The experimentals increased significantly more than controls in internal control. Students reported that the Open Campus experience led to: after school jobs, greater time to pursue own interests, feelings of freedom, autonomy, and responsibility, a decline in grades due to “goofing off,” and less time for social activities.  相似文献   

Locus of control and reading attitude     

Dorotha H. Brown  Ann W. Engin  Fred H. Wallbrown 《Psychology in the schools》1979,16(3):336-338

The relationships between three measures of locus of control and eight dimensions of reading attitude were investigated for a sample of 431 inner-city children. The sample included the intermediate grade children enrolled in the 20 regular classrooms of the three elementary schools from the Columbus, Ohio, Public Schools. Correlation coefficients were computed between locus of control scores and the eight dimensions of reading attitude. Reading Anxiety showed a significant relationship with the I- score. This finding suggests that inner-city children who are willing to accept personal responsibility for negative events in their lives also tend to experience more anxiety about their reading. The other seven dimensions of reading attitude were not significantly related to internality scores.  相似文献   

The impact of the National Curriculum on twelve special schools in England     

Ann Lewis 《欧洲特需教育杂志》2013,28(1):95-105

Abstract

The National Curriculum represents one of the most significant UK educational reforms of this century. However, it was planned and introduced with little reference to pupils with special needs, particularly those attending special schools or units. Alongside pragmatic responses to the implementation of the National Curriculum in special education, there has been a lively and continuing debate about its appropriateness, in principle, for pupils in special schools. This paper reports data derived from interviews with headteachers of twelve special schools (encompassing three distinct special needs groups). Continuities of view, notably an acceptance of the principle of a national curriculum for all pupils, are discussed. Divergent Views reflected an adherence to equality or individuality as underlying educational principles. The findings are placed in two contexts: first, the process of curriculum change, and second, the links between integration and curricular conformity as reflected in some European special education literature.  相似文献
