This study investigated the effects of different reduced strength training (RST) frequencies on half-squat 1 RM and quadriceps cross-sectional area (QCSA). Thirty-three untrained males (24.7?±?3.9 years; 1.73?±?0.08?m; 74.6?±?8.4?kg) underwent a 16-week experimental period (i.e. eight weeks of strength training [ST] followed by additional eight weeks of RST). During the ST period, the participants performed 3–4 sets of 6–12 RM, three sessions/week in half-squat and knee extension exercises. Following ST, the participants were randomly allocated to one of three groups: reduced strength training with one (RST1) or two sessions per week (RST2), and ceased training (CT). Both RST1 and RST2 groups had their training frequency and total training volume-load (i.e. RST1?=?50.3% and RST2?=?57.1%) reduced, while the CT group stopped training completely. Half-squat 1 RM (RST1?=?27.9%; RST2?=?26.7%; and CT?=?28.4%) and QCSA (RST1?=?6.1%; RST2?=?6.9%; and CT?=?5.8%) increased significantly (p?<?.05) in all groups after eight weeks of ST. No significant changes were observed in 1 RM and QCSA for RST1 and RST2 groups after the RST period, while the CT group demonstrated a decrease in half-squat 1 RM (22.6%) and QCSA (5.4%) when compared to the ST period (p?<?.05). In conclusion, different RST frequencies applied were able to maintain muscle mass and strength performance obtained over the regular ST period. Thus, it appears that RST frequency does not affect the maintenance of muscle mass and strength in untrained males, as long as volume-load is equated between frequencies.  相似文献

This essay comparatively examines U.S.-Russian and U.S.-Mexican interculturality in the Despicable Me movie franchise. We argue that cultural transformations of the main protagonists – Russian Gru and Mexican El Macho – are politically significant cases of U.S.-Russian and U.S.-Mexican interculturality, reflected and constructed by popular culture in general, and by animated cartoons in particular. Conceptualizing and analyzing animation as “equipment for living,” we demonstrate how these cases serve as epistemological and pedagogical tools of confirming U.S.-dominant ideology, and discursively and visually constructing (Russian and Mexican) Others the way that they are currently understood and treated in (the non-fictional) U.S. society.  相似文献

The age for the fastest marathoners is well investigated, but not the age and nationality of the fastest. We investigated the age of peak marathon performance for the annual top 100 women and men competing in four races of the “World Marathon Majors” (Boston, Berlin, Chicago and New York) and the “Stockholm Marathon” between 2000 and 2014 using mixed-effects regression analyses and one-way ANOVA. Race times of Ethiopian men decreased to 2:14 h:min, but remained unchanged for Kenyan (2:14 h:min), Moroccan (2:15 h:min) and South African (2:18 h:min) men. Race times in Ethiopian (2:34 h:min), Kenyan (2:29 h:min) and South African (2:49 h:min) women showed no changes. Age increased in Ethiopian and South African men to 29.0 ± 5.0 and 32.0 ± 1.0 years, respectively. Age for Kenyan (29.9 ± 2.0 years) and Moroccan (34.9 ± 3.9 years) men remained unchanged. Age remained unchanged for Ethiopian (26.5 ± 2.0 years), Kenyan (30.0 ± 0.8 years) and South African (36.3 ± 7.0 years) women. In summary, Ethiopian men improved marathon race times, but not Ethiopian women. Age increased in Ethiopian men, but not in Ethiopian women. For practical applications, female and male marathoners from Ethiopia were the youngest and the fastest.  相似文献

Skilled anticipation is underpinned by the use of kinematic and contextual information. However, few researchers have examined what happens when contextual information suggests an outcome that is different from the event that follows. We aimed to bridge this gap by manipulating the relationship between contextual information and final ball location in a cricket-batting task. We predicted that when contextual information is congruent with the eventual outcome then anticipation would be facilitated. In contrast, when contextual information is incongruent, this would lead to a confirmation bias on kinematic information and result in decreased anticipation accuracy. We expected this effect to be larger in skilled performers who are more able to utilise context. Skilled and less-skilled cricket batters anticipated deliveries presented using a temporally occluded video-based task. We created conditions whereby contextual information and event outcome were either congruent or incongruent. There was a significant skill by condition interaction (p < 0.05). The skilled group anticipated significantly more accurately than the less-skilled group on the congruent trials. Both groups anticipated less accurately on incongruent trials, with the skilled participants being more negatively affected. Skilled performers prioritise contextual information and confirmation bias affects the use of kinematic information available later in the action.  相似文献

The electrical resistivity tomography (ERT) represents one of the widely used geophysical techniques for the exploration of the subsurface. In the last few years, this method has been demonstrated to be an efficient reconnaissance tool not only for monitoring degradation status of walls and foundations of historical buildings, but also for imaging the spatial distribution of injected mortar, commonly employed for consolidation purposes. A 3D resistivity tomography survey was carried out on four selected wall portions of the historical church of Montepetriolo, Perugia, Central Italy. The obtained 3D resistivity distribution models before and after grouting provided suggestive images of the internal structure of the studied walls. Moreover, the spatial distribution of the zones being filled with mortar was determined quantitatively by scaling the post- to the preinjection resistivity values. Using a well known correlation between resistivity and porosity, established in the geophysical community, a further step towards a more quantitative assessment was attempted to indirectly determine the unit volumes of the injected mortar The obtained results were satisfactory and in some cases almost similar to the yard data. Furthermore, two flat-jack tests confirmed the local increment of the mechanical resistance of the studied left front (2) and right lateral (3) wall portions.  相似文献

At latest in the upper school, physical education (PE) offers opportunities to deal with games and sport not only in a motor but also in a cognitive manner. The present paper asks if and under what conditions an instructional design integrating theory and practice in PE promotes meaningful learning and knowledge construction. It brings out the less considered cognitive learning potential of upper school PE and advances hypotheses about their occurrence. The results of the empirical study show that pupils in upper school PE already use learning activities that promote meaningful learning. It also shows that meaningful learning activities are restricted to a self-regulated and intrinsic learning motivation. Intrinsic learning motivation itself is highly dependent on the pupils’ academic self-concept in PE.  相似文献

Neuroanatomy has been deemed crucial for clinical neurosciences. It has been one of the most challenging parts of the anatomical curriculum and is one of the causes of “neurophobia,” whose main implication is a negative influence on the choice of neurology in the near future. In the last decades, several educational strategies have been identified to improve the skills of students and to promote a deep learning. The aim of this study was to systematically review the literature to identify the most effective method/s to teach human neuroanatomy. The search was restricted to publications written in English language and to articles describing teaching tools in undergraduate medical courses from January 2006 through December 2017. The primary outcome was the observation of improvement of anatomical knowledge in undergraduate medical students. Secondary outcomes were the amelioration of long-term retention knowledge and the grade of satisfaction of students. Among 18 selected studies, 44.4% have used three-dimensional (3D) teaching tools, 16.6% near peer teaching tool, 5.55% flipped classroom tool, 5.55% applied neuroanatomy elective course, 5.55% equivalence-based instruction-rote learning, 5.55% mobile augmented reality, 5.55% inquiry-based clinical case, 5.55% cadaver dissection, and 5.55% Twitter. The high in-between study heterogeneity was the main issue to identify the most helpful teaching tool to improve neuroanatomical knowledge among medical students. Data from this study suggest that a combination of multiple pedagogical resources seems to be the more advantageous for teaching neuroanatomy.  相似文献

There is a dearth of research and writing on women's cricket in South Africa. In an attempt to enhance understanding of the nature and effects of women's involvement in the game of cricket over the past 200 years, this essay offers a chronological account of the sport and the role women played in it. It draws on readings from the international scholarship on women's early involvement in sport, the fragments that have existed to date about women's cricket in South Africa and some newly discovered primary material from the 1950s onwards. The essay aims to provide a historical context and open a window for historians and social analysts into an area few knew existed before. There is now a distinctive history and subculture of cricket with multiple social dimensions for scholars to explore; here I offer some preliminary insights.  相似文献

Objectives:

The 170-year history of the library of the Royal Society of Medicine in Budapest illustrates both that political and cultural context matter and that “medical” libraries, if they survive, in due course become primarily “medical history” libraries.

Methods:

Two of the authors are on the staff of the Semmelweis Medical History Library; the third is a US scholar who makes frequent use of the library. Together, they avail themselves of archival and published materials—and personal experience with the collection—to establish the context that produced the original library, trace its evolution, and describe its present-day incarnation.

Results:

A tale of transformation emerges that reflects how collections are likely to change. The authors present events and individuals in the life of the Royal Society''s library and paint a picture of the value of today''s Semmelweis Medical History Library. Unique treasures in the collection are described.

Conclusion:

The story told here is of how a particular nineteenth-century library became a twenty-first–century institution. The authors establish its peculiarly Hungarian context and potential value to librarians and historians from outside Hungary. The overall message is that general medical libraries everywhere are perforce likely to become medical historical libraries over time.

Highlights

  • Context matters. The historical background of a library helps determine its functions and its future; shifts in modes of publishing affect and monetary concerns shape the development and preservation of an historical collection.
  • Libraries evolve. Medical libraries undergo a normal and profoundly useful transformation over time into repositories of medical history.
  • Books alone do not a library make: Libraries can and should be settings for continuing education, cultural affirmation, and assistance to scholars by preserving and making available for use a variety of sometimes rare archival and published materials.

Implications

  • Knowing the political and cultural background of a library is essential to understanding its history as well as its present-day status.
  • Preserving and expanding historical collections demands vigilance and creative management, especially under difficult fiscal and political circumstances. The loyal and diligent work of Hungarians and others who helped build and preserve this library can serve as a model for other threatened collections.
  • Sharing the story of a relatively unknown library''s development brings its general assets and unique resources to the attention of a wider audience of librarians and scholars. Few outside Hungary have previously had any way of knowing about the Semmelweis Medical History Library''s rich holdings.
