This study was designed to examine the magnitude and duration of excess postexercise oxygen consumption (EPOC) following upper body exercise, using lower body exercise for comparison. On separate days and in a counterbalanced order, eight subjects (four male and four female) performed a 20-min exercise at 60% of mode-specific peak oxygen uptake (VO2) using an arm crank and cycle ergometer. Prior to each exercise, baseline VO2 and heart rate (HR) were measured during the final 15 min of a 45-min seated rest. VO2 and HR were measured continuously during the postexercise period until baseline VO2 was reestablished. No significant difference between the two experimental conditions was found for magnitude of EPOC (t [7] = 0.69, p greater than .05). Mean (+/- SD) values were 9.2 +/- 3.3 and 10.4 +/- 5.8 kcal for the arm crank and cycle ergometer exercises, respectively. Duration of EPOC was relatively short and not significantly different (t [7] = 0.24, p greater than .05) between the upper body (22.9 +/- 13.7 min) and lower body (24.2 +/- 19.4 min) exercises. Within the framework of the chosen exercise conditions, these results suggest EPOC may be related primarily to the relative metabolic rate of the active musculature, as opposed to the absolute exercise VO2 or quantity of active muscle mass associated with these two types of exercise.  相似文献

This study investigates professional autonomy as experienced by psychotherapists in Korea and in the United States using data collected as part of a collaborative international study of the development of psychotherapists (Orlinsky et al. (1999). Psychotherapy Research, 9(2), 127–153; Orlinsky & Rønnestad, (2005). How psychotherapists develop: A study of therapeutic work and professional growth. Washington, DC: American Psychological Association). The major aims are: to compare the extent of professional autonomy experienced by psychotherapists in Korea and by their counterparts in the USA; and to explore the professional and social correlates of the professional autonomy experienced by Korean therapists and compare these with the correlates of autonomy experienced by American therapists. These aims are pursued through analyses of a database of questionnaire responses. Results indicate that Korean therapists, compared to American therapists in our sample experience significantly lower levels of professional autonomy. For Korean therapists, whether they have a salient theoretical orientation in their practice is the single most important influence in their experience of work autonomy. Seniority and work setting are also significant correlates of autonomy for the Korean therapists. Similar to Korean therapists, seniority and having a salient orientation are also important influences on the way American therapists experience professional autonomy. American therapists, who work in independent practice experience higher work autonomy, whereas American social workers tend to experience lower professional autonomy.  相似文献

The validity and reliability of curriculum‐based measures in reading as indicators of performance and progress for secondary‐school students were examined. Thirty‐five grade 8 students completed reading aloud and maze‐selection measures weekly for 10 weeks. Criterion measures were the state standards test in reading and the Woodcock–Johnson III Test of Achievement. Different time frames for each measure were compared. Most alternate‐form reliability coefficients were above .80. Criterion‐related validity coefficients ranged from .77 to .89. No differences related to time were found. Only maze selection reflected significant growth, with an average increase of 1.29 correct choices per week. Maze growth was related to the reading performance level and to change on the Woodcock–Johnson III from pre‐ to posttest.  相似文献

Jenny Morris, freelance researcher, David Abbott, research associate at the Norah Fry Research Centre at the University of Bristol, and Linda Ward, Director of the Norah Fry Research Centre at the University of Bristol, carried out research to look at whether the current system of legislation and regulation is adequately protecting and promoting the interests of disabled children placed at residential schools. This article summarises some findings from the research which investigated the decision-making processes leading to residential special school placements and explored the involvement of education and social services authorities after placements have been made. The research found that the needs of individual children are not central to these decision-making processes; and that the local authorities who make such placements do not pay sufficient attention to protecting and promoting children's educational or care needs once they have gone away to school. Jenny Morris, David Abbott and Linda Ward indicate some of the ways in which current practice could be improved; make recommendations for future developments; and call for further research into the role of special residential schools in the context of policy on educational and social inclusion.  相似文献

This paper is an overview of the issues and concerns in the last decade of electronic records research. It highlights some achievement and identifies areas in which there remains a need for work, but mostly it examines the changing perception of what constituted the important questions in a field which was evolving quickly.  相似文献
