Scientists and practitioners in the field of physical culture and sports are trying to solve issues related to increasing the interest of children and youth in physical activity, especially during leisure time. One of the ways to increase physical activity is rationally organized leisure time based on the application of various health and recreational activities. The use of games in the recreational and health-improving activities of children and youth helps to optimize their motor activity, promotes the development of motor skills. The purpose of the study was to develop a program of leisure activities with priority use of badminton exercises for boys aged 13-14. The program development process included three stages: organizational, practical and control. The development of the program was based on the principles of leisure activities: principle of interest, individual approach, differentiated approach, consistency, systematicity, voluntariness, and compliance of leisure services with the existing conditions of the classes. The program lasted 6 months. The study involved 10 boys who attended classes three times a week. Each lesson lasted 60 minutes. The content of the program material was divided into blocks: general physical training, special physical training, technical training, and games, which also included outdoor games. The effectiveness of the training program is proven by the results obtained at the end of the study, which indicate an improvement in physical fitness indicators (strength by 13.6 %, agility by 2.8 %, flexibility by 15.5 %, speed and strength qualities by 5.1 %, speed - by 2.9 %) and motor activity of boys aged 13-14.

The article addresses studying the characteristics of physical activity regimen in middle-aged men who attend a health and fitness bowling club. The objective of the study was to examine the characteristics of physical activity in middle-aged men, in particular, to assess the time they spend in a sitting position. Methods. To determine the physical activity coefficient, the methodology of the International Health, Racquet, and Sportsclub Association modified by S. V. Nachinska and T. M. Parfenova (2003) was used. The study involved 106 adult-aged men (25-45 years old) who attended bowling clubs in Kyiv. Results. As a result of the study, it was found that the majority (>70%) of visitors of health and fitness clubs have low and below average levels physical activity, i.e. their actual physical activity does not exceed 6 hours per day or 40% of the recommended physical activity. The calculated physical activity coefficient of the study participants was on average 0.36 ± 0.07 points, which corresponds to the below average level and highlights the need to increase the amount of physical activity of middle-aged men. To investigate the characteristics of physical activity regimen, we applied time use approach and observation of the physical activity regimen. The majority of respondents have low and below-average levels of physical activity and a low motivation to participate in recreational health and fitness programs. Most of the study participants have a physical activity deficit despite the daily activity they engage in. The above necessitate the development and implementation of accessible health-enhancing and recreational programs aimed at increasing the level of involvement of middle-aged men.

Онтокінезіологічний підхід до фізичного виховання ґрунтується на усвідомленні складнощів рухової діяльності, оволодіння основами системного підходу до аналізу складних явищ м’язових рухів у всіх проявах. Мета дослідження полягала в теоретико-методологічному обґрунтуванні застосування онтокінезіологічного підходу до фізичного виховання студентів. Матеріал та методи. У ході наукової роботи проводили аналіз і синтез філософської, психологічної, педагогічної, загальнонаукової літератури, абстрагування й конкретизацію. Результати. Установлено, що такий підхід, розглянуто як метапредметний як базис спортивної науки, може використовуватися для побудови систему фізичного виховання студентів, що враховує інтеграцію інтелекту- альних і рухових здібностей у процесі фізичного виховання. Охарактеризовано поняття «кінезіологічний потенціал» та кінезіологічні компетентності. Розглянуто теоретико-методичниі підходи до розуміння кінезіологічних компетентностей, а саме антропологічний, культурологічний, особистісно-діяльнісний і компетент- нісний. Означено, що кожен підхід як підсистема включає обов’язкові елементи: поняття, принципи, форми й методи. Визначено основні педагогічні принципи фізичного виховання студентів. Висновки. Отже, педагогічна система фізичного виховання студентів, заснована на онтокінезіологічному підході, являє собою інтегративну єдність антропологічного, культурологічного, особистісно-діяльнісного й компетентнісного підходів, що сприяють досягненню поставленої освітньої мети. Системоутворювальним фактором побудови цієї системи є мета її функціонування – формування кінезіологічних компетентності студентів, що розглядається як здатність і готовність особистості до саморозвитку та самовдосконалення свого кінезіологічного потенціалу, що більшою мірою відповідає сучасним вимогам процесу фізичного виховання у вищій школі.

The study demonstrates the use of various nanomaterials (carbon materials, organic materials, nanocomposites, metals and metal oxides) for the electrodes in the voltammetric determination of drugs. The article presents the findings of the research aimed at increasing the number of identified organic compounds and pharmaceuticals using electrodes made of nanomaterials.

Quantum chemical calculation has been carried out for explaining experimental data of increasing sensitivity of quercetine voltammetric determination on organo-modified electrodes. Quercetin forms the strongest complex with functional group -Ph-COOΔG=-53,4 kJ/mole. For the groups -Ph-NH2 ΔG=-49,5 kJ/mole, and for -Ph-NO2 ΔG=-38,6 kJ/mole. The obtained results correspond by complexation constants with comparative experimental sensitivity values at quercetin voltammetric determinations. The mechanism of increasing sensitivity is explained by quercetin adsorption growth on electrode surface.

The article is devoted the study of the state of carriage of students of economic institute of higher in the process of physical education. The characteristic features of angular descriptions of body of students are exposed. As a result of an experimental research it is proved, that readiness for training is formed during employment and represents the generalized structure of impellent experience (physical readiness) and attitudes of students to the purposes, process and results of training. Motivational-valuable orientations and a kind of physical activity mean, which prefer students

The work is devoted to the development of a new voltamperometric (VА) way of definition of some vitamins and flavonoids on modified electrodes and methods of their definition in pharmaceuticals and vegetative raw material. Based upon the studies performed, method of superficial modification of graphite electrodes by tozylate arenediazonium salts is offered. Conditions are offered and technique of VА definition of vitamins and flavonoids on organ-modified electrodes in pharmaceuticals is developed.
