CHANGING SCHOOL-BASED ANXIETY DURING PHYSICAL EDUCATION, TAKING THE INDIVIDUAL TYPOLOGICAL APPROACH INTO ACCOUNT

Purpose of the study: The purpose of the study is to identify changes in school-based anxiety in children aged 12 – 13 during their physical education using a special Program for the individual typological approach implementation. Methodology: Two groups had been formed: reference and experimental (25 people each); three methods were used (Method for studying individual typological peculiarities of middle-school children by A. Belov, Method of Kondash's anxiety scale (1973), and Method of identifying general physical education of students); diagnostic testing of physical fitness was conducted (long jump from the spot; lifting the body in 30 sec. (press); push-up (girls); pulling up on the crossbar (boys); running 30 meters, shuttle running 3x10; bending forward from a sitting position). Main Findings: The results of the study have been statistically processed with Excel 2000 and STATISTICA 8.0, using the Student's t-test for dependent and independent samples. The M average has been found; the differences have been considered significant at p < 0.05. Applications of this study: The Program for the individual typological approach implementation has been compiled with an emphasis on reducing school-based anxiety in children aged 12 – 13; its features, objectives, indicators, criteria, content, and forms of implementation have been substantiated; a set of general physical exercises has been developed for each type of temperament, which includes the exercises for some groups of muscles of the upper shoulder girdle, back muscles, abdomen, and hips. Novelty/Originality of this study: The significant improvement in the physical fitness of students from the experimental group compared to the reference one identified during the term proves the efficiency of the implemented physical education program, taking into account the individual typological approach to the personality of adolescents with an emphasis on reducing their school-based anxiety. The results of the study have allowed formulating recommendations for improving the approaches to conducting physical education classes

Marrow hematopoiesis indices and lipoperoxidation content in the marrow of animals undergoing the emotional-painful stress

The article presents the results of experimental study of the emotional-painful stress effect on the number of indices in interrelation with the level of primary and secondary products of lipid peroxidation in the marrow. It is shown that 6-hour emotional-painful stress has caused the inhibition of eritropoieses in the marrow of experimental animals testifying the damage of their marrow tissue caused by it. The interrelation between marrow hematopoieses indices and indices of lipid peroxidation stress-realizing systems in marrow tissues of experimental animals has been revealed.В статье представлены результаты экспериментального исследования влияния эмоционально-болевого стресса на ряд показателей костномозгового кроветворения во взаимосвязи с уровнем первичных и вторичных продуктов перекисного окисления липидов в костном мозге. Показано, что в результате действия 6-часового эмоционально-болевого стресса наблюдалось угнетение эритропоэза в костном мозге у экспериментальных животных, что свидетельствует о повреждающем действии эмоционально-болевого стресса на ткань костного мозга. Выявлены взаимосвязи показателей костномозгового кроветворения и стресс-реализующей системы перекисного окисления липидов в ткани костного мозга у экспериментальных животны

Показаны количественно-качественные изменения эритропоэза в костном мозге при действии ЭБС, а также их восстановление в течение пяти суток после стресса. In article results of experimental research of influence of emotionally-painful stress on a number of indicators of hematosis in rats' marrow, in particular, erythropoesis's condition, are presented. The article presents qualitative changes of erythropoesis in a marrow, and also its normalisation within two days after stress
