Abstract

The aim of this study was to examine the acute response to plasma and salivary cortisol and testosterone to three training protocols. Ten trained endurance athletes participated in three experimental trials, such as interval training (INT), tempo run (TEMP) and bodyweight-only circuit training (CIR), on separate days. Blood and saliva samples were collected pre- and 0, 15, 30 and 60 min post-exercise. Peak post-exercise salivary cortisol was higher than pre-exercise in all trials (P < 0.01). After INT, salivary cortisol remained elevated above pre-exercise than 60 min post-exercise. Salivary testosterone also increased post-exercise in all trials (P < 0.05). Plasma and salivary cortisol were correlated between individuals (r = 0.81, 0.73–0.88) and within individuals (r = 0.81, 0.73–0.87) (P < 0.01). Plasma and salivary testosterone was also correlated between (r = 0.57, 0.43–0.69) and within individuals (r = 0.60, 0.45–0.72), (P < 0.01). Peak cortisol and testosterone levels occurred simultaneously in plasma and saliva, but timing of post-exercise hormone peaks differed between trials and individuals. Further investigation is required to identify the mechanisms eliciting an increase in hormones in response to CIR. Furthermore, saliva is a valid alternative sampling technique for measurement of cortisol, although the complex, individual and situation dependent nature of the hormone response to acute exercise should be considered.  相似文献

Since the introduction of nursing into tertiary institutions in Australia in 1975, there has been increasing interest in the teaching of physical science to nurses. Various courses in physical science for nurse students have been developed. They vary in length and content but there is agreement that concepts taught should be closely related to nursing applications. The choice of relevant concepts tends to be made by individual curriculum developers. This paper reports an examination of the use of physical science concepts and their relevance from the perspective of registered nurses practising in general ward areas. Inherent in this study is the premise that for registered nurses to have ideas of the physical science underlying their practice they must have constructed meaning first for these concepts. Specific chemical concepts related to solutions are discussed in these terms. Specializations: phenomenology, thinking, caring, euthanasia and palliative care, curriculum development for nurses. Specializations: thinking, science curricula for nurses, isotope geochemistry, mass spectrometry.  相似文献

In 1997, the DfEE suggested that schools should consider 'setting' pupils by ability as it was believed that this would contribute to raising standards. This survey of primary schools aimed to establish the extent to which primary schools, with same and mixed age classes, implement different grouping practices including setting, streaming, within class ability and mixed ability groupings for different curriculum subjects. Schools were asked to complete a questionnaire indicating their grouping practices for each subject in each year group. The findings showed that schools predominantly adopted within class ability groupings, either mixed or ability grouped, for most subjects. Ability grouping (within class and setting) was most common in mathematics, followed by English and science. Its implementation increased as pupils progressed through school. The type of setting adopted, same or cross-age, tended to reflect the nature of the class structures within the school.  相似文献

Using narrative inquiry as a research method, four mathematics and mathematics education faculty members explored the integration of theoretical perspectives into their personal narratives as they developed a community of practice. Initially their focus was strictly on improving their students’ mathematical knowledge. As their community of practice matured, however, their work took on a larger meaning as they contributed to the institution’s strategic goal of raising the annual dollar amount of external funding and to the development of their personal and collective identities. This unusual level of inter-departmental collaboration has been recognized by the institution’s highest administrators, who have called upon its members to develop new, collaborative partnerships with regional school districts and community colleges.  相似文献

The Microelectronics WebLab at MIT allows students to do actual (not simulated) laboratory research on state-of-the art equipment through the Internet. This study assesses the use of WebLab in a junior-level course on microelectronic devices and circuits in 2004–05 and 2005–06. In quantitative surveys and qualitative interviews, students and faculty reported that WebLab was effective as an instrument of learning, and grew more so with refinements of the program. WebLab allowed undergraduates to learn at their own pace and on their own schedules. It enabled them to use different processes of learning (intuitive, visual, abstract), and it gave them an opportunity to link individual and collaborative effort in creative combinations. Online laboratories on this model have broad applications in the experimental sciences and in other research-oriented disciplines.  相似文献

Mothers' Concepts of Young Children's Areas of Personal Freedom   总被引:2,自引:0,他引:2  
White suburban working- to upper-middle-class mothers ( N = 40) of children ages 5 and 7 were interviewed regarding their concepts of children's areas of personal discretion, autonomy, and individuality. Mothers treated standardized moral, conventional, and prudential items as issues that mothers should control, while standardized personal items were treated as up to the child. In open-ended interviews, mothers reported setting limits around issues of safety, family conventions, and daily routines but permitted children to make decisions about food, recreational activities, clothes, and playmates. Mothers viewed mother-child conflict as occurring over these same issues and viewed children's choices as helping them to develop autonomy and competence. Mothers viewed their roles as educators and nurturers and valued the development of individuality in their children, which was thought to emerge in infancy or toddlerhood. Few age differences were observed, but gender differences were found in the ways mothers characterized boys and girls' resistances to parental authority and in the content of mother-child disputes. Results were interpreted in terms of the emergence of the personal domain in children.  相似文献
