Participating in motor activities requires mastering the skill of swimming and adoption of principles of safe behavior. Achieving the stadium of swimming is one of the aims of Physical Education Curriculum and one of the criteria for adoption of the programme. A swimmer is an individual who has mastered the skill of swimming, diving, jump into the water, has adopted he habits (behavior which a part of self-protection and strategies of the general safety in and around the water area), gained knowledge (about swimming, self-estimation of the swimming skill and estimation of the surroundings for safe swimming, developed abilities which make him mobile and safe in water. A primary school teacher is identified a possible trainer of swimming and safety in water, and the school as an institution which can fulfill this aim. The subject of this paper is the very definition of a swimmer and the concept of training swimming and safety in water which can be realized in the Physical education classes.

Anaerobic threshold is considered an interesting and scientifically observed measure of physical working capacity in modern ergometry. Anaerobic threshold is defined as working intensity or oxygen consumption where we can notice for the following characteristics: blood plasma lactates increase, production and elimination of CO2 together with the simultaneous increase in respiratory exchange and pulmonary ventilation. The authors have shown two methods for determination of the anaerobic threshold: direct, in which we observe and monitor the concentration of lactates in blood plasma, and indirect, which is based upon observing the parameters of the gas exchange. According to the large number of researches, the authors have presented a considerable number of parameters which determine and describe the working intensity of the oxygen consumption in the area of energetic metabolism known as anaerobic threshold.

Physical education in the only educational subject oriented towards a student, his/her body, motor and cognitive knowledge, accepting values and gaining habits aiming at building a better life. Nevertheless, this pedagogical-educational area records many problems, both in its development and direct work with students. Reflection which is a cognitive method done for the praxis, theories and pedagogical documents of physical education in the area of swimming (the subject of the work), and this points at the fact that this teaching subject needs a new strategy and changes which according to the Physical Education Curriculum and Standards for the end of compulsory education integrated with the aim of training students for swimming and safety in water (the aim of the paper). Within the seven groups of knowledge of teachers (general, general-pedagogical, knowledge about the contents, knowledge about the curriculum, knowledge about the educational context, knowledge about a student and his characteristics, educational aims), this paper includes those concerning the curriculum and the educational aims, which in Serbia, have been placed in two separate but incompatible pedagogical documents, as the example of swimming tells us.

As a sports branch, swimming has been developing through the program of modem Olympic Games. During the period from 1957 until the Games in Atlanta in 1996 swimmers have broken world records 890 times (327 records being beaten during the Games). Competitions are described and analyzed, and the results from the games in Atlanta are stated (three world records). Bio-mechanical bastes (propulsion, resistance) of the new forms of swimmers' movement (diving) after the start and turn are stated, and the instructions for training are given. New forms of swimsuit and breath right are commented on. The performance of Yugoslav competitors (four swimmers, two divers, water-polo team) and their preparation for the Games are separately analyzed.

In the period from 2001 to 2009, a conscious effort was taken in Serbia on many occasions aimed at determining the ways of development of as many factors of the national sports system (NSS) and its associated environment as possible. The term "national mission of a sports visionary" in the title of this editorial indicates that the changes occurred thanks to the individual person. Using ex-post consideration of available material and through inductive reasoning, while striving to realize the vision of Predrag Manojlović, a scholar of progress and development in this field, the paper aimed at reaching conclusions about the professional and scientific foundation of changes in the NSS and the National Olympic Committee (NOC). In order to avoid a subjective approach to inferencing, the analyzed documents were compared with the results presented in periodicals of the same period in terms of their meaning, terminology, timeliness, action plans, etc. The results of this qualitati...

The subject of this paper concerns the nature of individual changes and the origin of organizational ones that have led to the progress and breakthrough results of competitive swimming in Serbia. Serbia's first swimming medals were won at the Olympic Games (OG), World Championships (WCh), and European Championships (ECh) in the senior and junior categories for both men and women, and the world and European records were set during the analyzed period (2000-2016). The Serbian male and female swimmers also marked the period concerned with winning the title of Serbia's best athletes in both senior and junior categories (2008 and 2009, 2010). Descriptive, structural, functional, and causal analysis of the facts related to this period of development of competitive swimming in the Republic of Serbia, as the method applied in this paper, led to the conclusion that the talent of an athlete, top coaches, in addition to new training practice, science, technology, innovation (NIT), SOFT...

Sestavení olympijského týmu pro Olympijské hry mládeže bylo iniciováno srbským NOC bezprostředně po Olympijských hrách v Pekingu. Program byl obsahově velmi bohatý a obsahoval optimální přípravu a stanovený rámcový program. Po hrách, ve kterých Srbsko získalo tři medaile (zlatou, stříbrnou a bronzovou), byla práce v oblasti sportu a opravdových olympijských hodnot ze strany IOC ale i odborníků a vzdělávacích i politických institucí velmi oceněna. Předmětem této studie je jednak účast na 1. Olympijských hrách mládeže, ale i uznání programu, s cílem rozšířit rámcové podmínky pro mladé účastníky a pro systém sportu v Srbsku.

The present study evaluated reproducibility of the inert gas rebreathing method to estimate cardiac output at rest and during cardiopulmonary exercise testing. Thirteen healthy subjects (10 males, 3 females, ages 23–32 years) performed maximal graded cardiopulmonary exercise stress test using a cycle ergometer on 2 occasions (Test 1 and Test 2). Participants cycled at 30-watts/3-min increments until peak exercise. Hemodynamic variables were assessed at rest and during different exercise intensities (i. e., 60, 120, 150, 180 watts) using an inert gas rebreathing technique. Cardiac output and stroke volume were not significantly different between the 2 tests at rest 7.4 (1.6) vs. 7.1 (1.2) liters min−1, p=0.54; 114 (28) vs. 108 (15) ml beat−1, p=0.63) and all stages of exercise. There was a significant positive relationship between Test 1 and Test 2 cardiac outputs when data obtained at rest and during exercise were combined (r=0.95, p<0.01 with coefficient of variation of 6.0%), a...
