Swimming in water is connected with different environment and thus the necessity of performing different movements in it. We usually swim in water of temperature lower than the body temperature; this prevents getting a common cold and hardens the organism. Water has exceptionally beneficial influence over the condition of respiratory system. The special way of breathing in water, called the ‘swimming breath’, increases the force of respiratory muscles and enlarges lungs breathing capacity as compared to the body surface area. The position most frequently taken while swimming is hori- zontal position. In connection with almost total elimination of the gravitational force influence and reduction of the hydrostatic pressure influence, it provides the optimum conditions of even blood supply to all tissues. Cyclical movements performed while swimming result in overcoming water resistance with individual frequency and this allows for improving the muscle force of the swimmer. Strength exercises of this type are particularly recommended for children and people requiring body compensation. Water and movement in water offer even further benefits positively affecting the widely understood human health. Only the major ones are presented here. At the same time, we do not even mention the utilitarian aspects of the swimming skill constituting a separate, extremely large area of knowledge. For these reasons, numerous research programmes are conducted worldwide, of results which document the importance of activity in water, irrespective if it is under- taken for recreation, health, rehabilitation or sport reasons. Researchers working in this field exchange their views at numerous seminars, conferences and congresses. Also, plentiful popular science and science works and studies on this subject are published all over the world. All the same, ordering and describing knowledge on swimming still requires extensive work. Thus, it seems that meetings of researchers studying various areas of swimming, held cyclically in Wroc³aw, may to some extent supplement the knowledge on the subject. A monograph Science in Swimming II continues presentation of interesting results of research projects conducted in various research centres all over the world. Since our last meeting, new research concepts have appeared; more modern methods and measuring instruments have been applied and new conclusions have been drawn based upon it. These conclusions will undoubtedly enrich knowledge and in many cases will become useful for all those dealing with implementing them in practice. The monograph contains issues related to the Swimming Education. In this area, it is worth paying attention to the innovative educational concepts connected with kinaesthetic differentiation, kinaesthetic sensitivity, swimming education of seven-year-olds or teaching effectiveness as a result of applying trademark teaching programme in the form of instruction. The next chapter – Swimming Technique – performs biomechanical analysis of young swimmers’ technique as a result of training in water, studies the influence of the movement form on movement stability, the interconnection between the co-ordination abilities and the sports results of 11–12 years old swimmers and presents objective (mathematic) methods of assessing learning progress and improvement of the swim- ming technique. Further research results are presented in the chapter about the issues connected with Swimming Training. It presents some interesting solutions, having influence, (as empirically documented), on the effectiveness of training. In this chapter it is worth paying attention to works on analysing selection of training exercise and re- sults of 12-year-old swimmers, metabolic reaction to reducing breathing frequency during effort making, stabilization of lactate concentration while swimming with criti- cal and maximum speed and frequencies of movement cycles, cyclical nature and selection of training exercises in preparing great class swimmers for competition, the relationship between the swimming pool length and assessment of critical speed of young swimmers in freestyle and finally the relationship between

  • The Country of Origin Effect on Sports Apparel Users' Brand Perceptions
    DOES COUNTRY MATTER? The Country of Origin Effect on Sports Apparel Users' Brand Perceptions Marketing Master's thesis Liisa Räty 2009 Department of Marketing and Management HELSINGIN KAUPPAKORKEAKOULU HELSINKI SCHOOL OF ECONOMICS HELSINKI SCHOOL OF ECONOMICS (HSE) ABSTRACT Department of Marketing and Management August 2009 Master’s Thesis Liisa Räty DOES COUNTRY MATTER? The Country of Origin Effect on Sports Apparel Users’ Brand Perceptions Objectives The purpose of this master’s thesis is to study the factors that affect consumers’ perceptions of a brand and determine if country of origin is one of these factors. Country of origin is divided into country of manufacture, country of design and brand origin to simulate the complexity of the country of origin concept in today’s highly globalized economy. All three elements of country of origin are thought to affect brand image directly and indirectly through intrinsic and extrinsic product cues. Consumer values are also thought to influence the way in which country of origin information impacts brand image. Methods Data was collected using a web‐based questionnaire that was sent out to 1326 licensed competitive swimmers whose contact information was acquired from the Finnish Swimming Federation’s database. The questionnaire contained 44 statements measuring the respondent’s attitudes toward goods, clothes and swimwear produced or designed in Asia or Western countries as well as the overall importance of country of origin information in decision making. 343 usable questionnaires were returned. The data was analyzed using the t‐ test and ANOVA to determine if males and females or the different age groups differed in their attitudes.

  • Athletics, Badminton, Gymnastics, Judo, Swimming, Table Tennis, and Wrestling
    INDIVIDUAL GAMES 4 Games and sports are important parts of our lives. They are essential to enjoy overall health and well-being. Sports and games offer numerous advantages and are thus highly recommended for everyone irrespective of their age. Sports with individualistic approach characterised with graceful skills of players are individual sports. Do you like the idea of playing an individual sport and be responsible for your win or loss, success or failure? There are various sports that come under this category. This chapter will help you to enhance your knowledge about Athletics, Badminton, Gymnastics, Judo, Swimming, Table Tennis, and Wrestling. ATHLETICS Running, jumping and throwing are natural and universal forms of human physical expression. Track and field events are the improved versions of all these. These are among the oldest of all sporting competitions. Athletics consist of track and field events. In the track events, competitions of races of different distances are conducted. The different track and field events have their roots in ancient human history. History Ancient Olympic Games are the first recorded examples of organised track and field events. In 776 B.C., in Olympia, Greece, only one event was contested which was known as the stadion footrace. The scope of the games expanded in later years. Further it included running competitions, but the introduction of the Ancient Olympic pentathlon marked a step towards track and field as it is recognised today. There were five events in pentathlon namely—discus throw, long jump, javelin throw, the stadion foot race, and wrestling. 2021-22 Chap-4.indd 49 31-07-2020 15:26:11 50 Health and Physical Education - XI Track and field events were also present at the Pan- Activity 4.1 Athletics at the 1960 Summer Hellenic Games in Greece around 200 B.C.

Higher expertise swimmers obtained faster average velocities and longer distances in all the turn phases (p < .001, ES = 0.59), except the approach distance. In addition, national level swimmers showed the ability to maintain most of the turn parameters throughout the race, which assisted them in improving average velocity at the end of races.
