BackgroudBlood flow restriction (BFR) with low-intensity resistance training has been shown to result in hypertrophy of skeletal muscle. In this study, we tested the hypothesis that BFR during the rest periods between acute, high-intensity resistance exercise sessions (70% of 1 repetition maximum, 7 sets with 10 repetitions) enhances the effects of the resistance training.MethodsA total of 7 healthy young men performed squats, and between sets BFR was carried out on one leg while the other leg served as a control. Because BFR was applied during rest periods, even severe occlusion pressure (approximately 230 mmHg), which almost completely blocked blood flow, was well-tolerated by the participants. Five muscle-specific microRNAs were measured from the biopsy samples, which were taken 2 h after the acute training.ResultsDoppler data showed that the pattern of blood flow recovery changed significantly between the first and last BFR. microRNA-206 levels significantly decreased in the BFR leg compared to the control. The mRNA levels of RAC-β serine/threonine-protein kinase v22, nuclear respiratory factor 1, vascular endothelial growth factor, lupus Ku autoantigen protein p70 genes (p < 0.05), and paired box 7 (p < 0.01) increased in the BFR leg. The protein levels of paired box 7, nuclear respiratory factor 1, and peroxisome proliferator-activated receptor γ coactivator 1α did not differ between the BFR leg and the control leg.ConclusionBFR, during the rest periods of high-load resistance training, could lead to mRNA elevation of those proteins that regulate angiogenesis, mitochondrial biogenesis, and muscle hypertrophy and repair. However, BFR also can cause DNA damage, judging from the increase in mRNA levels of lupus Ku autoantigen protein p70. 相似文献

This article examines the strategies that can be used to enhance students' understanding of how subjects link together and whether cross‐curricular approaches, through a gallery project, have any real impact on students' understanding of the links between subjects. A substantial part of this article, however, describes the methodological aspect of the project. A phenomenological case study approach was used in order to engage fully with individual students' learning experiences. It was found that the students who were involved directly with the study felt that the links between subjects had more relevance to their learning when the teacher made such links explicit. They were unaware of the relevance of many cross‐curricular links made in lessons, but the study indicated that cross‐curricular learning can enable students to transfer skills and knowledge in order to understand concepts more fully. 相似文献

This paper is devoted to the non-fragile exponential synchronization problem of complex dynamical networks with time-varying coupling delays via sampled-data static output-feedback controller involving a constant signal transmission delay. The dynamics of the nodes contain s quadratically restricted nonlinearities, and the feedback gain is allowed to have norm-bounded time-varying uncertainty. The control design is based on a Lyapunov–Krasovskii functional, which consists of the sum of terms assigned to the individual nodes, i.e., it is constructed without merging the complex dynamical network’s nodes into a single large-scale system. In this way, the proposed design method has substantially reduced computational complexity and improved conservativeness, and guaranties non-fragile exponential stability of the error system. The sufficient stability condition is expressed in terms of linear matrix inequalities that are solvable by standard tools. The efficiency of the proposed method is illustrated by numerical examples. 相似文献

In the last few decades, researchers are paying more and more attention to study the connections between sports and urban development. The main purpose of this study is to examine the changing role of sports in urban development through the example of Debrecen and to present the differences between the various historical periods. As a result, it can be concluded that on the one hand, in the inter-war years and in the period after 2000, the broader influence of sports was recognised, and local government made special efforts to use sports for the development of local economy, as well as for the improvement of the image of the city. By contrast, in the period between 1945 and 1990, the main approach used was from the side of mass sports, with satisfying the needs of workers and the general population deemed as the most important. On the other hand, from the early 1930s, i.e. from the beginning of urban planning (with the exception of the period during World War II and the 1950s), the leaders of the city paid special attention to ensure that sports facilities be included in the local development plans of Debrecen. 相似文献

Based on the experience of evaluating 2 cross-age peer-tutoring interventions, we argue that researchers need to pay greater attention to causal mechanisms within the context of school-based randomised controlled trials. Without studying mechanisms, researchers are less able to explain the underlying causal processes that give rise to results from randomised controlled trials. Studying implementation fidelity is necessary but not sufficient for causal explanation; the study of causal mechanisms through the application of mixed methods is also required. Due to the increasingly complicated nature of many classroom-based innovations that are subject to evaluation, and the potentially distal nature of hypothesised effects, particularly on attainment, programme theory and articulation of mechanisms are essential in enhancing causal explanation and promoting the accumulation of knowledge of what works and why in classroom settings. 相似文献

Starting in 2008, debate about potential hazardous effects from exposure to bisphenol A (BPA) migrated from the pages of scientific journals to the U.S. media, regulatory authorities, and state legislatures. In the context of deep scientific conflict about the existence of adverse health effects attributable to BPA, this article asks why it was the case that some state legislatures considered or adopted legislative bans on products made from BPA, whereas others did not. Drawing on existing theories of agenda-setting and policy change via punctuated equilibrium as well as a well-defined methodology (event history analysis), evidence of agenda-setting is presented. Particularly, it is argued that routine and high-impact health coverage was significantly related to the chance that a state legislature considered legislation banning products made with BPA. This was indirectly, but importantly, related to the actual adoption by state legislatures of legislative bans on products made with BPA. 相似文献
