Heat production and storage are positively correlated with measures of body size/composition and heart rate drift during vigorous running     

Buresh R  Berg K  Noble J 《Research quarterly for exercise and sport》2005,76(3):267-274

The purposes of this study were to determine the relationships between: (a) measures of body size/composition and heat production/storage, and (b) heat production/storage and heart rate (HR) drift during running at 95% of the velocity that elicited lactate threshold, which was determined for 20 healthy recreational male runners. Subsequently, changes in skin and tympanic temperatures associated with a vigorous 20-min run, HR, and VO2 data were recorded. It was found that heat production was significantly correlated with body mass (r = .687), lean mass (r = .749), and body surface area (BSA, r = .699). Heat storage was significantly correlated with body mass (r = .519), fat mass (r = .464), and BSA (r = .498). The percentage of produced heat stored was significantly correlated with body mass (r = .427), fat mass (r = .455), and BSA (r = .414). Regression analysis showed that the sum of body mass, percentage of body fat, BSA, lean mass, and fat mass accounted for 30% of the variability in heat storage. It was also found that HR drift was significantly correlated with heat storage (r = .383), percentage of produced heat stored (r = .433), and core temperature change (r = .450). It was concluded that heavier runners experienced greater heat production, heat storage, and core temperature increases than lighter runners during vigorous running.  相似文献   

Initial-link duration and acquisition of preference in concurrent chains     

Berg ME  Grace RC 《Learning & behavior》2006,34(1):50-60

Initial-link response allocation in concurrent chains becomes less extreme as the absolute duration of the initial links increases (Fantino, 1969). The present study asked whether initial-link duration affected how quickly response allocation reached asymptote (i.e., acquisition of preference). Six pigeons were trained on a concurrent-chains procedure in which the terminal links were fixed-interval (FI) 8 sec FI 16 sec or FI 16 sec FI 8 sec and were reversed every 20 sessions. Across conditions, all possible combinations of transitions between variable-interval (VI) 8-sec (short) and VI 24-sec (long) initial-link schedules were studied. Overall, the rate of acquisition was faster when the durations of the initial links preceding the reversal were short rather than long, and when the durations of the initial links following the reversal were long rather than short. By contrast, initial-link duration had no effect on acquisition or asymptotic measures of temporal control of terminal-link responding. These results support the core principle of delay-reduction theory (Fantino, 1969) that the impact of a conditioned reinforcer varies directly with initial-link duration, but also suggest that temporal learning during the terminal links proceeds independently of initial-link duration. nt]mis|These data were presented at the annual meeting of the Association for Behavior Analysis, Boston, May 2004.  相似文献

Dietary Fat Intake and Exercise Among Two- and Four-Year College Students: Differences in Behavior and Psychosocial Factors     

Carla J. Berg  Lawrence C. An  Jasjit S. Ahluwalia 《Community College Journal of Research & Practice》2013,37(5):388-396

Given the demographic differences among two-year colleges and four-year universities and the relatively limited access to health education and campus-based health resources, this study compares the frequency of limiting dietary fat intake and exercising among two- and four-year college students. A total of 2,265 undergraduate students aged 18–25 at a two-year college and a four-year university completed a 108-item online survey in October 2008. We found that two-year college students had less confidence, motivation, and intention to engage in healthy behaviors and reported fewer close friends who exercise regularly but more friends who eat high-fat foods. After controlling for age, gender, ethnicity, and parental education, two-year (versus four-year) college students less frequently limited dietary fat (F(2,2227) = 21.64, p < .001) and less frequently exercised ≥ 20 minutes a day (F(5,2232) = 14.21, p < .001). Thus, research should focus on developing interventions targeting the different psychosocial factors that influence nutrition and exercise among two-year college students.  相似文献   

Pregnancy and diabetes: how women handle the challenges          下载免费PDF全文

Berg M 《The Journal of perinatal education》2005,14(3):23-32

In order to optimize the possibilities for the birth of a healthy child, pregnant women with type 1 diabetes mellitus (type 1 DM) work hard to achieve normoglycemia. In the research presented here, pregnant, diabetic women's experiences of dealing with life circumstances are summarized as a construct of duality: "to master or to be enslaved." The overall experience of challenges and managing is understood to depend on the individual woman's identity, attitude, and resources including health professionals and social environment. Health professionals in antenatal care have a special responsibility to give care that not only optimizes the biological possibility for a healthy child to be born but also supports the woman with type 1 DM to master the situation and, thus, promote her health, well-being, and motherhood.  相似文献

Preservice teachers’ perceptions of an ICT-rich learning environment: Development of an instrument     

Adam Handelzalts  Ellen van den Berg  Geesje van Slochteren  Suzanne Verdonschot 《Learning Environments Research》2007,10(2):131-144

This article reports the development of an instrument to measure preservice teachers’ perceptions of the Study Landscape (SLS), which is an ICT-infused learning environment that encourages preservice teachers to direct their own learning to build a two-way relationship between theory and teaching practice. This study comprised a qualitative and quantitative part. Six factors derived from interviews with users formed the basis of the instrument: (1) Support of Learners’ Initiatives; (2) Support of Information Searches; (3) Support of Interaction; (4) Relationship with Fellow Students; (5) Relationship with Teacher Educators; and (6) Relationship with SLS Staff. Once developed, the questionnaire was responded to by 186 students. Analysis of the data supported five out of six factors.  相似文献   

Highbrows in University Education     

Adriaan Hofman  Muriel van den Berg 《Higher Education in Europe》2004,29(4):509-521

Is it still possible to combine two programmes of study in higher education, and if so, what are the characteristics of these double‐students and what kind of obstacles do they face? In the Netherlands, about 10 percent of students in university education take two studies at the same time.

Different theoretical approaches offer hypotheses to explain the choice of students for a second study, compared to students who pursue the regular one‐study programme. Human capital as well as financial (socio‐economic) capital theory provides some insights in this choice process. Education programme‐related factors, as well as motivational and (social and academic) integration (Tinto, 1987 Tinto V 1987 Leaving College: Rethinking the Causes and Cures of Student Attrition Chicago The University of Chicago Press  [Google Scholar]) factors, will possibly be important determinants for pursuing one or two study programmes in higher education.  相似文献
