ABSTRACT

Interval exercise training is increasingly recommended to improve health and fitness; however, it is not known if cardiovascular risk is different from continuous exercise protocols. This systematic review with meta-analyses assessed the effect of a single bout of interval exercise on cardiovascular responses that indicate risk of cardiac fibrillation and infarction compared to continuous exercise. Electronic databases Medline, CINAHL, Embase, Scopus and Cochrane were searched. Key inclusion criteria were: (1) intervals of the same intensity and duration followed by a recovery period and (2) reporting at least one of blood pressure, heart rate variability, arterial stiffness or function. Cochrane Risk of Bias tool and GRADE approach were used. Meta-analyses found that systolic blood pressure responses to interval exercise did not differ from responses to continuous exercise immediately (MD 8 mmHg [95% CI ?32, 47], p = 0.71) or at 60 min following exercise (MD 0 mmHg [95% CI ?2, 1], p = 0.79). However, reductions in diastolic blood pressure and flow-mediated dilation with interval exercise were observed 10–15 min post-exercise. The available evidence indicates that interval exercise does not convey higher cardiovascular risk than continuous exercise. Further investigation is required to establish the safety of interval exercise for clinical populations.  相似文献

Open-field behavior of wild and domestic Norway rats     

Edward O. Price  U. William Huck 《Learning & behavior》1976,4(2):125-130

The open-field behavior of wild and domestic Norway rats was compared in 15-min tests administered over 5 successive days. Wild rats exhibited more ambulation, jumping, grooming, and time inactive than domestic rats and spent more time along the arena wall. Within- and between-trial changes in behavior were generally greater for wild rats. Factor analyses revealed major loadings on factors identified as “locomotor behavior” and “grooming.” Support was obtained for the hypothesis that domestication has raised the threshold for avoidance-escape behavior in response to a novel environment.  相似文献

Teaching with technology in higher education: understanding conceptual change and development in practice     

Claire Englund  Anders D. Olofsson  Linda Price 《高等教育研究与发展》2017,36(1):73-87

Research indicates that teachers’ conceptions of and approaches to teaching with technology are central for the successful imple-mentation of educational technologies in higher education. This study advances this premise. We present a 10-year longitudinal study examining teachers’ conceptions of and approaches to teaching and learning with technology. Nine teachers on an online Bachelor of Science in Pharmacy and a Master of Pharmacy programme at a Swedish university were studied using a phenomenographic approach. Results showed clear differences between novice and experienced teachers. Although novice teachers initially held more teacher-focused conceptions, they demonstrated greater and more rapid change than experienced colleagues. Experienced teachers tended to exhibit little to no change in conceptions. Supporting conceptual change should, therefore, be a central component of professional development activities if a more effective use of educational technology is to be achieved.  相似文献   

A study of race and gender bias in the punishment of handicapped school children     

Anna C. McFadden  George E. Marsh II  Barrie Jo Price  Yunhan Hwang 《The Urban Review》1992,24(4):239-251

There is scant research concerned about punishment of handicapped, minority students in public schools. The purpose of this study was to investigate race and gender, types of rules violations, types of punishments, referral rates, referral frequencies, and follow-up activities to determine differences in treatment by race, sex, and handicapping condition. The sample consisted of 4,391 discipline files representing records from 9 schools in a district (K-12). All data were analyzed using the Chi Square statistic. It was demonstrated that racial bias existed in the administration of punishment, and that Black, male handicapped students were punished more severely than others for commission of the same offenses.  相似文献   

The Influence of Teacher Expectations about Twice-Exceptional Students on the Use of High Quality Gifted Curriculum: A Case Study Approach     

Tracy C. Missett  Amy Price Azano  Carolyn M. Callahan  Kimberly Landrum 《Exceptionality》2016,24(1):18-31

Twice-exceptional students show evidence of high academic performance or potential and also have a disability that impedes their ability to learn. Twice-exceptional students remain under-represented in gifted programs, and some researchers attribute such under-representation to the negative beliefs and low expectations about twice-exceptional students held by teachers. While researchers have begun to investigate the curricular models and instructional strategies that are effective for twice-exceptional students, little research addresses how teacher beliefs and expectations about student ability are reflected in the ways teachers implement such models and strategies for twice-exceptional students in gifted classrooms. Even less research addresses gifted students with emotional and behavioral disabilities. We used a case study of a third-grade teacher using a structured, model-based language arts curriculum to better understand how her expectations about a gifted student with an emotional disability influenced her instructional choices. Using observational and interview data, the case study approach allowed the researchers to personalize the experiences of this teacher and provided a context in which to examine the subtleties of teacher expectations when teaching a gifted student with an emotional disability. Implications for educational practice, particularly the need for comprehensive school-based support systems for students with emotional disabilities, are discussed.  相似文献

Disconnections Between Teacher Expectations and Student Confidence in Bioethics     

Nikki L. Hanegan  Laura Price  Jeremy Peterson 《Science & Education》2008,17(8-9):921-940

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation.  相似文献   

Learning to Play Soccer: Lessons on Meta-cognition from Video Game Design     

Amy Price  Dave Collins  John Stoszkowski  Shane Pill 《Quest (Human Kinetics)》2018,70(3):321-333

Over the past decade, there has been ongoing debate relating to the use of suitable pedagogical approaches for designing learning environments to develop skillful games players. There has, however, been little consideration of the “digital age of learning” and the global success of the digital video game industry. Using the educational work of James Gee, this article attempts to rationalize how a “digital video games approach” differs from other learner-centered pedagogies currently employed for teaching and coaching games. Examination of the literature suggests that the learning gains from Teaching Games for Understanding and the Constraints Led Approach ignore the meta-cognitive dimension of learning how to play games—surely an important consideration for long-term development. Accordingly, by drawing on experiences from digital video game design, we examine how games practitioners might utilize such an approach for meta-cognition in coaching or teaching practice to stimulate player learning.  相似文献
