Analysis of students’ nervous system’s typological properties, in aspect of response to extreme situation, with the help of multi-dimensional analysis
No full textPurpose: determination of objective and subjective characteristics of students’ with different properties of nervous system fear of heights. Material: In the research 10 students of 18-19 years old age, who did not practice sports, participated. The students fulfilled one exercises: passing suspended ferriage in hiking. This exercise gives subjective perception of height and creates artificial conditions for appearing of fear. He exercise was fulfilled under all required safety measures and supervised by experienced instructor. Cluster and discriminant analysis were used. Results: we have shown that is possible to divide people into groups by indicators of functional changes in extreme situation in combination with indicators of psycho-physiological potentials and properties of nervous system. We have found that the most significant indicators for distribution of students into groups by individual typological properties are speed and accuracy of passing of psycho-physiological tests with different modes of signals’ supply as well as functional changes before exercise of extreme character. Conclusions: It was determined that students with strong type of nervous system had confidently less heart beats rate before fulfillment of extreme exercise than the students with weak type of nervous system. Subjective feeling of fear before fulfillment of extreme exercise was also confidently less in representatives of strong type of nervous system

Development dynamic of healthy life style personality component in relatively healthy students
Get PDFPurpose: to determine effectiveness of different physical culture trainings for development of students’ healthy life style personality components. Material: 1st - 3rd year students, trained at physical culture lessons, participated in the research. All students related to main health group (students, having no health problems). In total 803 students participated in the research. The testing was conducted in periods from 2001 to 2005 and from 2010 to 2015. Results: positive changes of different personality’s component of healthy life style were observed. Parameters of emotional stability and tolerance were found. Teaching in last years develops personality’s components to less extent. The highest changes were determined in 3rd year students, independent on the program of their training. We did not find differences in degree of trainings’ influence of specialized and typical classes. Conclusions: at trainings it is necessary to pay more attention to development personality’s components of healthy life style, especially emotional stability and tolerance in respect to other people

Biomechanics aspects of technique of high jump
No full textThe purpose of work consists in the theoretical ground of optimum biomechanics descriptions in high jumps. A mathematical model is developed for determination of influence on the height of jump: speed and corner of flight of centre-of-mass during pushing away, positions of centre-of-mass body of sportsman in the phases of pushing away and transition through a slat, forces of resistance of air environment, influences of moment of inertia of body. The basic technical run-time errors of sportsman are selected exercises. To biomechanics descriptions, to the step-up effectiveness of high jumps belong: speed of flight of centre-of-mass sportsman (4.2-5.8 meters in a second), corner of flight of centre-of-mass body (50-58 degrees), height of flight of centre-of-mass body (0.85-1.15 meter). Directions of choice of necessary biomechanics descriptions which a sportsman can realize are shown. Offered recommendation on the increase of effectiveness of high jumps
Studying of interconnectios of morphological functional indicators of students, who practice martial arts
No full textPurpose: to study interconnections of students’ morphological functional indicators and their influence on level of sportsmanship. Material: in the research 17 students, practicing martial arts, participated. 62 indicators were determined: anthropometrical, goniometrical criteria of arms joints’ status; tapping test and maximal frequency of grabs in impulse mode. Results: we found that maximal contribution in system is made by hand dynamometry of right and left hands, body length and mass, chest circumference, width of shoulders; maximal frequency of grabs by right and left hands. It was confirmed that there are correlations between students’ morphological functional indicators. The highest contribution to formation of functional system is characteristic for anthropometric indicators. Results of maximal grabs in impulse mode made rather sufficient contribution in system’s formation that is confirmed by great quantity of correlations. Analysis of character, strength and orientation of correlations witnesses about informative potential of this test and permits to recommend it as screening for control of sportsmen’s state. Conclusions: we determined that indicators of hand dynamometry system formation illustrate that for martial arts wrestlers strong grab was very important. It is ensured by strength of hand muscles
Reliability of functioning and reserves of system, controlling movements with different coordination structure of special health group girl students in physical education process
Get PDFPurpose: to study reliability of functioning and reserves of system, controlling movements with different coordination structure of special health group girl students (low health level) in physical education process. Material: in the research special health group girl students (n=136, age 17-19) participated. They were divided into 2 groups - control and experimental. The program, directed to increase reliability and reserves of system controlling movements, was realized. It was based on physical exercises of complicated coordination with novelty elements, which were fulfilled under musical accompaniment. The research continued one academic year. Results: in girl students with health problems we registered higher differential thresholds, when reproducing local movements in complicated conditions. They used visual and hearing feedback channels for informing brain’s programming areas about made mistakes. They were worse teachable in training accurate movements. These girl students have less expressed compensation reserves under impact of hindering factors and interferences. It can be interpreted as non-specific crisscross negative response to motor functional system in case of health problems. All these determine reduction of reserve potentials of motor control system. Conclusions: The main reserve potentials’ criteria of control over different coordination structure movements are: quickness of passing to program mechanism of fine movements’ regulation in stable conditions of functioning; power and effectiveness of compensatory reactions, ensuring interference immunity of system, controlling movements under interfering factors; reliability of maintaining movements’ qualitative parameters in optimal range under interfering factors; reduction of sensor interconnections in stable functioning conditions
Influence of studying in higher educational establishment on students’ harmful computer habits
Get PDFPurpose: to determine influence of educational process on prevalence of students’ harmful computer habits. Material: in the research 1st-3rd year students (803 boys and 596 girls) participated. All they specialized in discipline Physical culture. The students had no health disorders. Results: it was found that in average students have 2 computer habits everyone. The most probable and dangerous in respect to addicting are habits to use internet and computer games. Student, who has these habits, spends more than 4 hours a day for them. 33% of 1st year boys and 16% of 1st year girls spend more than 2 hours a day for computer games. 15-20 % of boys and 25-30% of year girls waste more than 4 hours a day in internet. 10-15% of boys spend more than 4 hours a day for computer games. It is very probable that these students already have computer games’ addiction. Conclusions: recent time dangerous tendency to watching anime has been appearing. Physical culture faculties and departments shall take additional measures on reduction of students’ computer addictions. Teachers of all disciplines shall organize educational process with the help of electronic resources so that not to provoke progressing of students’ computer habits
Features of physical development, physical preparedness and functional state of boys and girls – students of Polish higher educational establishments
No full textThe features of level and structure of indexes of physical development, physical preparedness and functional state of students are considered. In research 50 took part students of Higher School of Sciences about health from Bydgoshch (14 boys and 36 girls, age 18-29 years). Reliable distinctions are exposed in physical preparedness and functional state of boys and girls on the indexes of force. Indexes of psychophysiological possibilities, frequencies of heart-throbs in a state of rest, the index of Ruf'e have no reliable distinctions at boys and girls. It is shown that power capabilities have the most value in complex preparedness of boys. Functional and psychophysiological possibilities have the most value in complex preparedness of girls. The factor structure of preparedness of girls is differ by greater complication as compared to boys. On the level of physical preparedness and functional state of girls in a greater degree of anthropometric information have influence as compared to boys. Power capabilities for girls occupy middle position in the general structure of preparedness, while for boys' power capabilities occupy leading position. It is shown that on employments on physical education of boys it is necessary to do an accent on development of force, while for girls - on development of endurance (functional possibilities) and in a greater degree as compared to boys it is necessary to take into account psychophysiological possibilities
