The purpose of this study was to investigate the effects of interval aerobic training combined with strength exercise in the same training session on body composition, and glycaemic and lipid profile in obese rats. Sixteen lean Zucker rats and sixteen obese Zucker rats were randomly divided into exercise and sedentary subgroups (4 groups, n = 8). Exercise consisted of interval aerobic training combined with strength exercise in the same training session. The animals trained 60 min/day, 5 days/week for 8 weeks. Body composition, lipid and glycaemic profiles and inflammatory markers were assessed.
Results showed that fat mass was reduced in both lean and obese rats following the exercise training (effect size (95% confidence interval (CI)) = 1.8 (0.5–3.0)). Plasma low-density lipoprotein–cholesterol and fasting glucose were lower in the exercise compared to the sedentary groups (d = 2.0 (0.7–3.2) and 1.8 (0.5–3.0), respectively). Plasma insulin was reduced in exercise compared to sedentary groups (d = 2.1 (0.8–3.4)). Some exercise × phenotype interactions showed that the highest decreases in insulin, homeostatic model assessment-insulin resistance, fasting and postprandial glucose were observed in the obese + exercise group (all, P < 0.01). The findings of this study suggest that interval aerobic training combined with strength exercise would improve body composition, and lipid and glycaemic profiles, especially in obese rats. 相似文献

In this article Abraham Lincoln is considered as an alternative to the usual type of patriot's hero. He reminds us of our great historical failings. He remains a figure of controversy, a national hero in only some corners of society. He is the heroic President who serves as the first compassionate defender of the downtrodden, and he is a hero in those subcultures as well. Lincoln's treatment in the movies is discussed, focusing particularly on the recent movie Lincoln. Lincoln is seen as a match for the usual movie hero. His famous immunity to casual treatment in popular culture is discussed as well. 相似文献

The aim of the study was to determine the impact of peer mediation programmes at a secondary school, as compared to another centre that did not have any such programme. The impact would be evaluated by means of three levels of variables: pro-victim attitudes, the roles adopted by the youngsters and the school climate (this last item was analysed from two perspectives: that of the pupils and that of the teachers). In order to attain this goal, students from 12 to 14 years old (N = 323) and 17 teacher-tutors were administered different questionnaires in Time 1 (baseline, prior to intervention) and Time 2 (after programme intervention). Results highlight the validity of peer mediation programmes when it comes to fostering pro-victim attitudes, preventing the increase of negative roles and improving the school climate. 相似文献

ResumenEsta investigación trata, en líneas generales, sobre los factores que influyen en el desarrollo de ta memoria. En ella se enfatiza el papel del conocimiento previo del sujeto, frente al de las estrategias mnemónicas deliberadas, como responsable del incremento del nivel de recuerdo en los niños de E.G.B. Este trabajo es congruente con la Teoría de los Niveles de Procesamiento de la Información propuesta por Craik y Lockart (1972) y revisada por Craik y Tulving (1975). En el experimento se demuestra que aquellos niños a los que se les da una información previa congruente con la información a recordar obtienen mejores resultados mnésicos que aquellos que carecen de ella. Por último se hace una serie de consideraciones pedagógicas basadas en los resultados obtenidos en el experimento. 相似文献

In recent years there has been a spectacular increase in concern within society about problems of service and, in particular, that of university teaching. Teaching quality can be understood as a goal to be achieved in three nurtured phases: course planning; the adoption of a methodological approach; and the evaluation of the results. The teaching of statistics in engineering schools raises common problems as well as certain others specific to each qualification. In this article, proposals are made about how to improve the quality of teaching of statistics to undergraduate engineering students. 相似文献

This study aimed to analyse the association of different components of physical fitness, body composition, cardiometabolic markers and the Mediterranean diet with bone mineral density (BMD) in perimenopausal women, and to test which of these components are independently associated with BMD. The sample comprised 197 perimenopausal women (52.6 ± 4.5 years). Physical fitness was assessed with the “Senior Fitness Test” battery and the handgrip strength and Bruce tests. Fat and lean mass and BMD were measured using dual-energy X-ray absorptiometry. We analysed the markers of metabolic syndrome, C-reactive protein, and components of the Mediterranean diet. Handgrip muscle strength (β = 0.212, P = 0.005), body weight (β = 0.244, P = 0.001), BMI (β = 0.180, P = 0.011) and lean mass (β = 0.379, P < 0.001) were positively associated with BMD. No associations were observed between cardiometabolic markers or the Mediterranean diet with BMD (all P > 0.05). When all relevant indicators of BMD were simultaneously considered, lean mass was the only 1 showing an independent association with BMD (β = 0.392, P < 0.001), explaining 14% of the BMD variability. In conclusion, muscle strength might be a marker of BMD in perimenopausal women. However, lean mass was the only factor independently associated with BMD. Future research to determine whether increasing lean mass through specific exercise-based interventions contributes to increasing BMD is warranted. 相似文献

Two experiments assessed the degree to which Pavlovian facilitators were interchangeable with instrumental discriminative stimuli (Sds). In Experiment 1, rats were trained in a Pavlovian paradigm in which one stimulus (i.e., a facilitator) signaled the reinforcement of another stimulus (i.e., a target). Next, the rats were given instrumental discrimination training in which an Sd signaled the reinforcement of barpressing. A transfer test then assessed the capacity of the Pavlovian facilitator to promote barpressing. The results showed that the facilitator promoted significant barpressing, both when it was presented alone and when it was presented in compound with the Sd. Reliable transfer was not obtained with a “pseudofacilitator” control stimulus that, during training, was uninformative about the reinforcement of its target. Experiment 2 showed that a stimulus trained as an instrumental Sd reliably augmented responding to a stimulus previously trained as a target in a Pavlovian facilitation paradigm. A “pseudo-Sd” that, during training, was uninformative about the reinforcement of barpressing failed to promote such transfer. These results show that Pavlovian facilitators and instrumental Sds are interchangeable to a significant degree, and suggest that facilitators and Sds may act via similar mechanisms. 相似文献

The widespread adoption of computers and Internet in our life has reached the classrooms, where computer-supported collaborative learning (CSCL) based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work, we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study. 相似文献
