There is the content of lactate dehydrogenase in youth blood with the various levels of physical training during the athleticism training.
Get PDFIt was established that the primary data do not extend beyond the norm (195 - 462 unit of litre), but show us the specified action (increase and decrease of LDG in the blood) by various kinds of dimension index and intensity of physical activity of the groups. The process of adaptation to a three-month training cycle loads are accompanied by a decrease in average group levels of LDG in the blood by 4.4% after a training lesson in comparison with the dormancy. It was established that the process of change in the level of LDG in the blood of participants of the groups significantly affect the structure and various kind of the training components, consequently during the athleticism trainin
ВАРИАБЕЛЬНОСТЬ СЕРДЕЧНОГО РИТМА У НЕТРЕНИРОВАННЫХ ЮНОШЕЙ В УСЛОВИЯХ РАЗЛИЧНЫХ РЕЖИМОВ СИЛОВОЙ НАГРУЗКИ
Get PDFAim: to study features of variability of a rhythm of heart at unexercised young men under the influence of power loadings in the conditions of application of certain training modes in the course of long occupations by athleticism. Patients and methods: 40 young men participated in inspections at the age of 19–20 years, not having contraindications for occupations with burdenings. Research of indicators of training loading of both groups used by representatives in the course of occupations conducted a method of definition of an index of training loading in athleticism. For determination of values of indicators of the statistical and spectral analysis of a rhythm of heart the Polar RS800CX cardiomonitor was used. Control of studied indicators at rest and after power loading carried out for 3 months of occupations by athleticism with an interval in 1 month. Results: use in the course of occupations by athleticism of power loadings with large volume of work and low intensity considerably increases activity of the central mechanisms of neurohumoral regulation of a rhythm of heart due to decrease in parasympathetic activation of autonomous nervous system on sinusovy knot of heart, than loading of high intensity with a small volume of work. Conclusions: the result of long-term adaptation to occupations by athleticism, in the conditions of different modes of loading, is characterized by existence of an ekonomization of functioning of cardiovascular system of the unexercised contingent.Цель исследования: изучить особенности вариабельности ритма сердца у нетренированных юношей под влиянием силовых нагрузок в условиях применения определенных тренировочных режимов в процессе продолжительных занятий атлетизмом. Пациенты и методы: в обследованиях участвовали 40 юношей в возрасте 19–20 лет, не имеющих противопоказаний для занятий с отягощениями. Исследование показателей тренировочной нагрузки, используемых представителями обеих групп в процессе занятий, проводили методом определения индекса тренировочной нагрузки в атлетизме. Для определения значений показателей статистического и спектрального анализа ритма сердца применяли кардиомонитор Polar RS800CX. Контроль исследуемых показателей в состоянии покоя и после силовой нагрузки осуществляли на протяжении 3 мес занятий атлетизмом с интервалом 1 мес. Результаты: использование в процессе занятий атлетизмом силовых нагрузок с большим объемом работы и низкой интенсивностью значительно усиливает активность центральных механизмов нейрогуморальной регуляции ритма сердца за счет снижения парасимпатической активации автономной нервной системы на синусовый узел сердца, нежели нагрузки высокой интенсивности с малым объемом работы. Выводы: результат долговременной адаптации к занятиям атлетизмом в условиях разных режимов нагрузки характеризуется экономизацией функционирования сердечно-сосудистой системы нетренированного контингента.
Methodological aspects of values for determining the physical load in sport.
No full textThe main aspects of the control system of training in sport and identified two methodological concepts determine the amount of physical activity during the training sessions. It is established that the physical training and sports activities in the course of employment estimate the value of physical activity mainly due to the reaction rates of the functional systems of the body to an external stimulus. Such an assessment, especially in a narrow range of controllable parameters (for the reaction of the cardiovascular and respiratory systems), is more theoretical in nature and does not allow to clearly define the critical load levels for a particular organism. This problem highlights the need to use a single, integrated, suitable for precise mathematical analysis of the universal, possibly conditional, indicator or criteria for evaluating physical activity. Development of this criterion will optimize the training process at different stages of training opportunities tailored to individual athletes
Nature of changes in body composition indices in students during physical training using a set of athleticism.
Get PDFDuring investigations it was established that there are important changes in body composition parameters university students, who in the classroom with the general physical culture introduced by the training facilities with athleticism. The level indicators of body composition and dynamics are fully dependent on the employment structure, volume and intensity of physical exertion their focus. It is established that achieving the optimal performance of body composition may occur even with minimal training work. Planning sessions with physical cultures s light variation of volume and intensity of stress, achieves the required level of adaptation processes
Contents hormone cortisol in the blood youths with different levels of physical training and its changes in the single training sessions under athleticism
Get PDFObtained and summarized the results of studies indicate that the content of the hormone cortisol when exposed to body exercise power orientation exhibits rapid reaction type, which have no signs of consolidation over the three years of occupation by force sports. The studies found that reducing the amount of cortisol in the blood, fixed after the training load in all four study groups, showing a certain dependence on the magnitude and intensity of training loads, and possibly on the level of fitness
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
