Full textAbstract:
This paper provides a mathematical description based on the theory of differential equations, for the dynamics of lactate production and removal. Analytical and numerical results for training/exercise of endurance of athletes are presented based on the common concept of training impulse (Trimp). The relationships between activity, production rate, and removal strategies of lactate are studied. Parameters are estimated from published data. A model for optimum removal of lactate after exercise is developed. The model provides realistic predictions when compared with experimental results. We show some specific examples for the usefulness of the mathematical model by studying some recent problems discussed in the literature. (a) Is interval exercise more beneficial than steady-state exercise? (b) What is the optimum aerobic power during recovery? We discuss whether steady-state exercise gives higher Trimp than interval exercise, when imposing an upper boundary for the lactate concentration as a constraint. The model allows for testing all imaginable kinds of steady-state and interval exercises in search of the optimal exercise regime for individuals with various kinds of characteristics. In general, the dynamic model constitute a powerful tool describing the processes by which the concentration of lactate can be studied and controlled to decrease fatigue and increase endurance.

Full textAbstract:
The level of person’s physical activity belongs to the main criteria of one’s status. A high work ability level proves one’s strong health status, as well as low level of work ability is believed to be a health risk factor. Health preservation and restoration by means of health-improving fitness exercises becomes one of the most up to date problems. Nowadays, there is no hesitation considering positive influence of physical exercises on one’s physical and psychological health, improvement of one’s cardiovascular, respiratory and hormonal systems, as well as one’s physical qualities development. Health-improving fitness exercises are very popular among women (tae-bo, kibo, pump, terra- aerobics, slide, pilates). Such types of exercises enable to extend the influence of physical activity on one’s organism.
 The purpose of the research is to reveal the influence of different types of health-improving exercises on women’s physical and working ability.
 Methods of the analysis: the analysis of scientific and scientific methodological resources, pedagogical observation, medical-biological methods, methods of mathematical statistics.
 Results of the research have proved that Tabata is the most effective kind of health-improving fitness exercises, which increases working ability for 16 %. Zumba is less efficient – 14%. Body Pump exercises demonstrate the lowest level of productivity – 9%. We assume that such quantitative difference is determined by different health directivity and content of the exercises. High efficiency level of those who practice Tabata and Zumba is inherent in the aerobic nature of the exercises. Body Pump exercises are mainly focused on improving body shape, which makes them less effective.
 In conclusion we may claim that Body Pump, Tabata and Zumba health-improving exercises have a positive influence on women’s physical and working ability.

Full textAbstract:
The Ortvay Rudolf international competition was first organized in 1970. The focus is usually not on routine school-level problems but rather on problem-solving relying on physical reasoning and skills in recognizing the fundamental character and “heart” of the problem. Some problems lead the contestants to so-far unsolved, open questions, while some are accessible to first-year students. However, only for a relatively small number of problems do official solutions exist. The intention of this paper is to be the first in a series of published solutions discussing the competition problems. The problem treated below is a simple exercise about heat transfer in a thermodynamic system, which highlights the limitations and consequences of accepting seemingly intuitive approximations, and gives a didactical example of “explosive” dynamics. The calculation does not use mathematical techniques beyond those commonly expected of high school students.

Full textAbstract:
We describe our efforts at the University of Oregon to use Web-based Instructional Technology (IT) supplemented with interactive Java virtual experiments to change the standard pedagogy associated with large, introductory undergraduate classes in physics and astronomy. We begin by examining some of the problems associated with the standard pedagogy in these classes and how these problems motivated our development of networked courseware. Although we identify and describe five empirical positive outcomes associated with IT, we conclude that the use of HTML-based course material and assignments does not substantially alter the standard pedagogy as this medium alone is not conducive to interactive exercises. To build interactivity into our courseware, we have undertaken a vigorous effort of creating Java-based experiments which are grounded in physical reality and duplicate the kinds of experiments that are done in the physical lab. In so doing, we build experimentation into a curriculum for large lecture-based classes in which the standard pedagogy and resource constraints normally preclude lab sections. The main goal is to create a networked environment where the student can easily retrieve the notes and the demonstrations that were done in class as well as to engage in experiments that are designed to illustrate basic principles. In so doing, we hope to move to a more learner-centered environment which is driven by student inquiry. Five specific Java experiments are described here and each is accompanied by a snapshot of the experimental apparatus and controls. An appendix contains the relevant URLs of the experiments, courseware, and animation described herein.

Full textAbstract:
In view of the differences and uniqueness of intelligence between people, the application of new educational thoughts is the need of the time; in the educational atmosphere created by the intelligent environment, it is urgent to seek a path of integration and symbiosis. This article takes the development of children's sports driven by the intelligent education project as the main research object, selects our city's children's football as the representative of sports events to carry out case studies, and uses the spectrum education program to explore the intelligent development of intelligent children with logical and mathematical advantages in the field of sports. This paper designs a data fusion method for homogeneous smart sensors. The correlation degree of the nodes in the continuous sampling period is obtained by defining the spatial correlation coefficient, and the confidence value and coherent degree of integration are obtained by applying the angle of attraction between nodes in the definition of fusion strategy in the evaluation of neighborhood, and lastly, the node coefficient of weight is reallocated to validate the fused expression. The feasibility of the simulation is used to confirm the trustworthiness of the solution. Based on the development status of children’s physical education, this article uses intelligent mobile networks to find out the problems in the physical education classes of kindergarten teachers and the problems that are not compatible with the development of children’s physical education. The kindergarten normal students receive targeted physical education and acquire solid professional skills. The study indicates that the percentage of basic motor and basic motility classes in the city's kindergartens is 100%, suggesting that all preschools in the city operate fundamental motor practice classes for a group of children. They have fully realized that basic movement exercises have an impact on children’s body shape.

Full textAbstract:
The article addresses the problems of physical fitness assessmentand physical fitnessnormsin respect to foreign servicepersons who study in Russian military educational institutions. The general level of physical fitness inforeign enrollees is rather low, arguably due to the internal policies of other countries regarding physical culture and youth education and the personal attitude of servicepersons. As a result, suchprimary tasks of the educational process as physical training and improvement of moving motor abilities that would be typical for the university level, have to be replaced with general physicaldevelopment and learning of the secondary school level. Consequently, the inability to meetthe physical training standards becomes a challenge for many foreign military studentsduring thefoundation course and the first years of training. It takes more time for them to train themselves to meet the university level requirements to physical fitness and master the discipline of physical training. The relevance of the study roots the contradiction between the need for mastering a large amount of knowledge and skills, the low level of general and special training of foreign enrollees, and the demanding physical fitnessnorms for military personnel. The purpose of the study was to develop reference physical fitnessnorms that could be further readjusted, for foreign military enrollees. The study relied on such scientific and pedagogical methods as theoretical analysis of scientific literary sources, pedagogical observation, control physical fitness tests, mathematical and statistical data processing. The outcome of the study was the proposedreference norms for the exercises included in the control physical fitness battery for foreign enrollees. This approach to setting physical fitness norms can be applied both to one person and to a group of military students who fall behind in physical training, including servicepersons and students of civilian educational institutions. The proposednorms and the method of determining the physical training norms help foreign enrolleesto achieve the required minimum and get a positive grade in the first years of training, and to adapt to the specifics and content of the discipline.
