The purpose of this study was to determine if a difference in interleukin-6 (IL-6) and delayed onset muscles soreness (DOMS) exists in two different phases of the menstrual cycle. Nine runners performed one 75-min high-intensity interval running session during the early follicular (EF) phase and once during the midluteal (ML) phase of the menstrual cycle. Estrogen and progesterone levels were significantly reduced in the EF phase when compared to the ML phase. IL-6 levels increased from pre- to postexercise in the EF and ML phases (p < .001). There was no relationship between the IL-6 level and DOMS. The results suggest that menstruating female runners need not vary training throughout the month to reduce DOMS.  相似文献   

Psychological Mood Profiles of Sighted and Unsighted Beep Baseball Players

Purpose: Decline of motor performance in older individuals affects their quality of life. Understanding the contribution of sport-related training in advanced ages might help to attenuate motor performance decay as one gets older. The purpose of our study was to evaluate the extent to which long-lasting training in running or sport-specific skills during old age preserves motor performance in different motor tasks. Method: Older runners and tennis players with at least 10 years of training were assessed as were age-matched and young exercisers. Performance was evaluated for 6 motor tasks requiring different functions of sensorimotor control expected to decline with aging. Results: Analysis revealed that runners had increased aerobic fitness in comparison with the other older participants and that they presented similar performance to older exercisers in the motor tasks. Tennis players outperformed the other groups of older participants on coincident timing and simple reaction time and achieved similar performance to the young group on the timing task. Conclusions: These results suggest selective maintenance of task-specific processing through extensive practice of tennis-related motor skills in older adults.  相似文献   

The Effects of a Group Contingency Strategy on Behaviorally Disordered Students in Physical Education     

E. William Vogler  Ron W. French 《Research quarterly for exercise and sport》2013,84(3):273-277

Abstract

An A-B-A-B time-series design was used to determine the effectiveness of a group contingency strategy in modifying on-task behavior of behaviorally disordered students in a physical education setting. A younger group (n = 12) with a mean age of 7.8 years, and an older group (n = 11) with a mean age of 11.2 years, participated in a study in which activity reinforcement for each group was contingent upon correct observation of the rules established for class. The group contingency strategy was significantly effective in increasing the percentage of on-task behavior of both groups of students. In addition, there was no significant difference in the response to treatment between younger and older students, and there were no individuals within either group who did not respond favorably to treatment.  相似文献   

Economic stress, parenting, and child adjustment in Mexican American and European American families   总被引：1，自引：0，他引：1  

Parke RD  Coltrane S  Duffy S  Buriel R  Dennis J  Powers J  French S  Widaman KF 《Child development》2004,75(6):1632-1656

To assess the impact of economic hardship on 111 European American and 167 Mexican American families and their 5th-grade (M age=11.4 years) children, a family stress model was evaluated. Structural equation analyses revealed that economic hardship was linked to indexes of economic pressure that were related to depressive symptoms for mothers and fathers of both ethnicities. Depressive symptoms were linked to marital problems and hostile parenting. Paternal hostile parenting was related to child adjustment problems for European Americans, whereas marital problems were linked to child adjustment problems for Mexican Americans. Maternal acculturation was associated with both higher marital problems and lower hostile parenting. The utility of the model for describing the effects of economic hardship in Mexican Americans is noted.  相似文献   

The Correspondence Principle and the 1988 Education Reform Act     

Lucy Bailey 《British Journal of Sociology of Education》1995,16(4):479-494

This article applies the correspondence thesis devised by Bowles and Gintis (1976) to the 1988 Education Reform Act. Theoretical shortcomings of the thesis are identified, and a reformulated version is suggested which incorporates resistances into the analysis of the education system. More limited claims for the thesis are posited. The Education Reform Act is then explored with reference to the revised correspondence principle. Building on the work of previous theorists, it is argued that we may be seeing shifts to post-Fordist education, although contradictions and tensions in this movement are identified. It is suggested that the quasi-market in education is to some extent a change in the legitimating processes of reproduction, rather than a change in what is being reproduced.  相似文献   

The impact of fostering relationships through music within a special school classroom for students with autism spectrum disorder: an action research study     

Katrina Skewes McFerran  Grace Thompson  Lucy Bolger 《Educational Action Research》2016,24(2):241-259

Music therapists have been working in special education contexts for many decades, utilising research and case studies to inform practice. Growing interest in the link between the creative arts and well-being has led music therapists to consider what aspects of their knowledge others could feasibly appropriate in the school system. An action research approach was utilised to explore this question, grounded in partnerships between university-based music therapy researchers and staff at a school for learners on the autistic spectrum. Five cycles of planning, action, observation and reflection framed the collaborative partnership, with a music therapist acting as consultant to explore how music could be used across the school day. The greatest shift evidenced through qualitative and quantitative analysis was in the area of relationship building. Rather than seeing music as a tool that supports the acquisition of specific skills, the professionals and students in the school came to understand that music could be a meaningful part of their encounter with one another. This is congruent with music therapy research findings that also emphasise the ways music can be used to motivate, evoke and elicit meaningful responses from young people. Some limitations were identified in the sustainability of music practices in the school, particularly when other parts of the school culture were changing.  相似文献

Classroom Activities and Areas: Regularity of Use and Perceptions of Adaptability by General Early Educators     

Mark Wolery  Carol Schroeder  Catherine G. Martin  Martha L. Venn  Ariane Holcombe  Jeffri Brookfield  Kay Huffman  Lucy A. Fleming 《Early education and development》1994,5(3):181-194

This report describes a mail survey of general early educators from Head Start, public school pre-kindergarten, public school kindergarten, and community preschool/child care programs. The purposes were to secure information about the availability of classroom activities and areas, and to obtain the respondents' perceptions of the ease with which activities and areas could be adapted to accommodate children with disabilities. Of the 893 mailed questionnaires, 483 (54.1%) were returned and coded. The respondents reportedly used a wide range of classroom activities and areas, and they rated those activities and areas as moderately easy to adapt. Also, respondents from mainstreamed programs used slightly more activities and perceived the activities as easier to adapt than did respondents from non-mainstreamed programs. The findings appear to indicate that placement of children with disabilities in segregated programs cannot be justified on grounds that integration will restrict the range of activities available to typically developing children, or on the grounds that the adaptations are perceived by program staff as too difficult to be accomplished.  相似文献

Itinerant Booksellers: Necessary Evils to the Book Trade in Ghana?     

Kwasi Opoku-Amankwa  Anatu Kande Mahama  Lucy Ry-Kottoh 《Publishing Research Quarterly》2012,28(3):250-258

Itinerant booksellers play very significant but less noticeable role in the book trade in Ghana and many developing economies. They are the mobile booksellers who carry their collections to the doorsteps of their consumers. This paper highlights the contributions of itinerant booksellers to book distribution in Ghana. The paper makes a case for and against itinerant bookselling in Ghana. First, the paper raises issues with the quality and content of some of the reading materials peddled by the itinerant booksellers and discusses their implications for copyright and book development. The paper then argues that in spite of their shortcomings, itinerant booksellers have the potential to assist in finding a lasting solution to the book distribution problems of the country, and, need to be encouraged and assisted by book industry players such as the Ghana Development Council, Ghana Book Publishers Association, and the Ghana Booksellers Association to contribute meaningfully to Ghana??s book business.  相似文献
