Women\u27s in Fitness Social Belonging and Physical Activity in the Context of Quality of Life
Get PDFForming as many interpersonal relationships as possible is one of the most important goals in peoples’ lives. Mutual physical activities create a basis for social belonging. Therefore, the goal of the study is to determine the correlation between the components of social belonging and physical activity among women in fitness. The social belonging analysis was conducted with the use of questionnaires (adopted in Latvian), and a shortened version of IPAQ to determine the levels of physical activity. The components of social belonging were defined, and several weak, but significant, correlations between these components and the level of physical activity were found. According to the data obtained in the current study we can conclude, that social belonging has positive impact on PA. Those, who more often feel the relatedness, satisfactory from interpersonal relationship and inclusion in the social groups are more physically active. In order to evaluate, how the quality of life aspect of social belonging for women in fitness correlates with physical activity, they must be taken into account.
Characterization of Attack Element Execution Speed in Taekwondo ITF
No full textTaekwon-do as a combat sport technique has a characteristic feature – very fast element execution, and it is one of the factors that determine how successful is a fight. One of the main tasks of the training process is to develop kick speed both in attack and counterattack, where an athlete should react adequately and execute a purposeful element as fast as possible to overtake his opponent.
In the training process a coach tries to perfect an athlete’s technique and increase his speed ability. But the question arises how to test whether the applied method and means have increased the speed of the element execution by the trainee. In many cases the result will be stated subjectively observing the kick imitation or element execution in training or competition fights. In the best case the result will be measured using a stopwatch, the fighter executing several kicks, taking the total execution time and dividing it with the number of kicks.
To evaluate objectively both the execution of the element technique (trajectory) and speed and acceleration in different kicking phases, it is necessary to apply more effective instrumental methods and carry out a detailed movement analysis. Nowadays technologies with high-speed video (100 Hz and higher) allow us to evaluate these parameters objectively. In many countries research is carried out in different combat sports as karate, taekwondo WTF (World Taekwondo Federation) etc. Unfortunately in Latvia such research is not so widespread and is done only in some kinds of sport. So, it is valuable to introduce new technologies to research technique and speed ability in taekwon-do ITF (International Taekwondo Federation), that will help to organize, perfect and control the study-training process better.
The aim of the research was stating of the attack element execution speed in taekwon-do ITF. The data registration was done in LASE wrestling hall on taekwon-do ITF special mat. Movement analysis was performed using two high speed Basler A602fc cameras (100 Hz) and SIMI Motion software. Light-reflecting markers were placed on three body landmarks: hip (Trochanter Major), knee (Condylus Lateralis) and ankle (Malleolus Lateralis). The research subject was a black belt (dan 1) taekwondo fighter (age: 26 years; height: 165 cm; weight: 60.1 kg; experience in sport: 15 years), first, second and third place winner at national and international tournaments. The present research is a pilot study; the experimental setup and necessary adjustments of methodology were tested using with participant, aiming at a further development of the research
ESSENTIAL CHARACTERISTICS OF THE FITNESS CONCEPT AND THE AREA OF FITNESS IN LATVIA AND THE WORLD
Get PDFDespite the great popularity of fitness around the world, it is still unclear what fitness is and how people understand it. The essence of fitness has gradually evolved from simple physical fitness to a cultural phenomenon. The second path of fitness development is from the physical health of a person reflected in a person’s readiness to do physical work to the desire to improve their own quality of life. That is why the aim of this study was to investigate in depth the essential characteristics of the fitness concept and the area of fitness. The study is based on 41 literature sources and scientific articles, 8 of which are in Russian and 33 – in English. The essence of the content of the fitness concept has been investigated and the hierarchy of concepts has been evaluated in different theoretical contexts, starting from the historical beginning of the fitness concept. Definitions were grouped in a broader and a narrower sense: 1) fitness as a set of attributes and abilities and 2) fitness as a way of life, lifestyle and quality of life. The essential categories of the fitness concept were compiled. The change of fitness area and its influence on the society was discussed. By summarizing the analysis of fitness definitions and evaluating fitness according to various theoretical aspects, it can be concluded that fitness is interpreted as sport competition fitness, as an implementation of a healthy way of life and as physical fitness or health-oriented physical fitness. Due to constant change and improvement of the body ideal sometimes it is complicated to participate in the process of improving health, also achieving it requires a lot of energy and time. People don’t understand where is the difference between healthy body and fitness body prepared for competition or commercial. Therefore the greater the beauty industry and fitness area becomes, the weaker becomes the human.
CHARACTERIZATION OF THE ESSENCE OF THE HUMAN PHYSICAL CAPITAL CONCEPT IN RELATION TO THE FITNESS INDUSTRY
Get PDFA large part of the society perceives the body as a fundamental tool to advance in social life, as a capital in labour relations and in sexual relations as well. The possibility to transform one’s own physical capital into economic, social or cultural capital, which is an opportunity a person receives through carrying out physical activity, is also a value in the field of fitness which is an industry that is worth billions. That is why the aim of this study was to investigate in-depth characterization of the nature of the physical capital concept, linking it to the field of fitness. The study is based on 48 literature sources and scientific articles, 2 of which are in Latvian, 5 in Russian and 41 – in English. The essence of the content of the physical capital concept has been investigated and the connections of notions in different theoretical contexts has been evaluated, starting from the beginning of the physical capital concept. The definitions were grouped in a broader and narrower scope. In the narrower sense, physical capital is a person’s skills and abilities – innate or acquired over time –, which help to perform a specific physical work, move, strengthen or improve physical health and capacity for work. In the broader sense – as values and investments in the body, building of a body in society. In the broader sense of physical capital, the main goal is its transformation into other forms of capital in order to obtain additional benefits or a new status in the society.
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
