Abstract:
Background and Study Aim. The objective of the work consisted in studying the ratio and interconnections of functional fitness structure key components of elite combat athletes in the process of adaptation to physical loads at the stage of individual capacity maximum realization. Material and Methods. 55 highly skilled wrestlers aged 19-27 years old, members of the national teams of Ukraine in different styles of wrestling - freestyle, Greco-Roman, judo were examined. The assessment of wrestlers’ functional fitness structure was made according to a complex of indices of physiological systems activity at rest and during performance of a block of testing physical loads on a bicycle ergometer. Results. The components of functional fitness structure of male combat athletes of three wrestling styles (Greco-Roman, freestyle and judo) were studied according to the manifestations of the respiratory and circulatory functions during testing loads performance, and achieved indices of work capacity. It has been revealed that the key integrative components of the general structure of wrestlers' fitness include: the level of special work capacity, general level of functional fitness, mobility of physiological processes, economy, anaerobic power. Greco-Roman wrestlers are superior to freestyle wrestlers and judokas in anaerobic power, mobility and economy. The greatest differences are manifested in the values of anaerobic power, mobility and general level of functional fitness, whereas the least - in indices of economy. The key criteria for the functional fitness of wrestlers in the manifestation of a high level of physical work capacity include: economy of functioning at rest and during muscular activity of anaerobic-aerobic nature, high reactivity of the cardiovascular system to physical load, power of the anaerobic energy supply system, the rate of recovery processes, the state of cardiac activity regulatory mechanisms, the level of metabolic processes and excitability of the heart muscle. The level of development and the ratio of the components of functional fitness structure of elite combat athletes may be used as the reference models for development of differentiated scales for estimation of the key constituents of physical state of wrestlers specialized in freestyle, Greco-Roman wrestling and judo. Complex application of different methods of testing athletes provides more efficient approach to the problem of monitoring and managing functional fitness and special work capacity of wrestlers at the stage of maximum realization of individual capacities. Conclusions. An increase in the proportion of key integrative functional indices in special work capacity of athletes specialized in various wrestling styles - Greco-Roman, freestyle and judo represents the most significant criterion for improving their functional fitness structure.

Abstract:
Background and Study Aim. The present study investigated the effect of a 5x5 exercise program on sleep quality, fatigue, neck pain, head posture, daily walking, sitting, sleeping and smartphone usage time. Material and Methods. An exercise program was applied to 54 university students (17 males, 37 females) between October and November 2019. The five exercises lasted approximately 15- 20 minutes in each training session (diaphragmatic breathing, axial neck extension, cervical stabilization, pectoral stretch, and shoulder retractor strengthening) that was performed 5 times a day, 5 days a week for 5 weeks. The Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), Neck Disability Index (NDI), Forward Head Posture (FHP), number of daily steps, sitting time, sleep time, and smartphone usage time were compared before and after the exercise program. The Paired Samples t-test was used to compare differences between the pre-exercise and post-exercise variables. Statistical significance level was set at 0.05. Results. Following the 5-week exercise program, sleep quality improved, and levels of neck disability and fatigue were lower and the differences were statistically significant (p0.05). Conclusion. The 5-week program of posture correction, stretching and strengthening exercises improved sleep quality, fatigue levels, and neck disability. The findings of this study can be used to improve the sleep quality, fatigue and neck problems of both students and sedentary workers.

Abstract:
Background and Study Aim. There is a significant amount of data on the stressful effects of exercise, which contain conflicting results. Some publications testify to the adaptive processes and the benefits of optimized exercise for various physiological systems, some deny such an effect. Much controversial is the question of combination the physical exercises of different intensity with other stressors. The purpose of the study: to analyze the parameters of lipid metabolism and oxidative-antioxidant system in persons aged 18-23 who lived in territories with different radioecological status, under conditions of moderate physical activity during exercise. Material and Methods. There were examined 50 students from relatively ecologically clean areas (control group) and 50 students from the IV radiation zone (experimental group). The radiation zone is selected by the dosimetry of soil contamination with 137Cs isotopes after the Chornobyl catastrophe. Age of the examined is 18-23 years. Within the framework of the experimental group there were formed two subgroups: the main group for physical training classes (without signs of morphological-functional disorders) and the group for therapeutic physical training classes (TPTC, persons with signs of vegetative-vascular dystonia syndrome). For the control and experimental main group, classes contained all the planned exercises due to the standard curriculum. The program included a combination of aerobic and strength exercises of moderate intensity. For students with signs of vegetative-vascular dystonia, teachers used specially designed therapeutic exercise complexes. The first analysis of parameters was carried out the day before physical training classes, the second one – immediately after the class. Results. Higher levels of total cholesterol and its lipoprotein fractions (LDL-C and HDL-C), triglycerides, oxidative stress index are detected in the experimental group compared to the control group. At the same time lower levels of sulfhydryl groups (SH) were marked. The absence of statistically significant changes in the analyzed parameters in the control group and the experimental therapeutic group after physical exercises is shown in the study. There were evident tendencies of ceruloplasmin level increase in the control along with the absence of such trends in persons with signs of vegetative-vascular dystonia syndrome. This led to the formation of a significant difference between groups for this antioxidant. There is a significant increase in cortisol level and oxidative stress index in the main group of students from radiation contaminated areas. Conclusions. Potentiation of various stress factors in persons who experienced the prolonged exposure to Chornobyl accident reduces the adaptive potential of homeostatic systems. This eliminates the optimization of lipid metabolism and oxidative-antioxidant system through moderate exercise. Exercise therapy does not cause a pronounced stress effect.

Abstract:
Background and Study Aim: The article presents the results of analyses of students’ foot pressure distribution on the ground, as well as their body balance before and after exercise (Harvard Step Test). The aim of the paper was to carry out a comparative analysis of foot pressure distribution on the ground, as well as assess the degree of body balance before and after exercise. With that purpose in view, the following research hypothesis was formulated: in the students participating in the study, the distribution of foot pressure on the ground and the degree of body balance differ significantly after physical effort compared with the at-rest conditions. Material and Methods: The study encompassed n=48 students, including 37 women and 11 men. The tests were carried out using such tools as: an EPS/R1 podobarographic mat and the impedance methods – i.e. the InBody 270 body composition analyser. An analysis was performed for the parameters concerning body composition, the distribution of foot pressure on the ground, and the level of body balance. Results: The results obtained revealed statistically significant differences in the physiological parameters of foot arching and the functional efficiency of the body balance system under different measurement conditions that reflected the impact of effort stimuli. Conclusions: Significant differences reflecting the impact of the effort stimuli were expected to be achieved during the mathematical analysis of the results of podobarographic tests that allow for the assessment of the physiological parameters of foot arching and the functional efficiency of the body balance system under different measurement conditions. The authors’ assumption was mathematically and statistically confirmed by significant differences foe most of the parameters arising out of the possibilities offered by the research method applied. Comparative assessment unquestionably revealed a negative change in foot arching, as well as lower body posture stability in the female and male subjects, resulting from the physical exercise applied.

Abstract:
Background and Study Aim. The aerobic fitness in soccer is an important performance component. The aerobic endurance level of players may positively effect performance of critical match activities. The examination of Yo-Yo intermittent recovery test (YYIRT) performance of young soccer players at different playing positions was aimed in this study. Material and Methods. The research group was consisted of 75 young soccer players playing at U-21 category of professional soccer teams at different leagues. The soccer players at 5 different playing positions participated in study voluntarily (centerback: n=15, fullback: midfielder: n=15, winger: n=15, forward: n=15). The YYIRT (level 1) was performed for determination aerobic endurance parameters (covered distance during test, maximum oxygen uptake (VO2max) and maximal aerobic speed (MAS) of players. The one-way ANOVA analysis was used for comparison between playing positions of YYIRT parameters. Results. It was determined that difference between YYIRT parameters of players at different playing positions was non-significant (p>0.05). However, the midfielders covered more distance (2425,33±440,42 m) than forward (2146,67±339,64 m), winger (2137,33±615,18 m), fullback (2056,00±512,43 m) and centerback (1960,00±313,51 m) players. The positional requirements of midfielders may be decisive on covered distance during YYIRT. Conclusions. Consequently, it may be said that the young soccer players at different playing positions had similar YYIRT performance and the playing position effect on YYIRT performance could vary depending on league level and individual features of players.

Abstract:
Background and Study Aim: The target of this paper was to examine the effects of strength training with different frequency on physical, performance and strength features on untrained university male students. Material and Methods: 24 subjects (age= 21.47+1.50) were divided into three groups; 8 for strength training group once a week (ST1), 8 for strength training group three times a week (ST3) and 8 for control group (CG). The training groups were applied a 6-week ST that lasted approximately 80-90 minutes for each training 3 days a week for ST3 and once a week for ST1. Analysis of intergroup, intragroup and the effect of training were carried out with repeated measures ANOVA. Significance was set at 0.05. Results: There was no difference in body weight and body mass index values in training groups, while a significant increase was found in CG. In addition, there was a significant decrease in body fat percentage and a significant increase in skeleton muscle mass without any change in body weight and body mass index in ST3. No statistical difference was seen in 10-20 m sprint and agility tests in all groups. For vertical jump, balance test for right and left leg, there was a significant difference between the pre and post-test measurements of ST1 and ST3. In standing long jump measurements, significance was seen in favor of ST3. In strength parameter, while a significant difference was detected in bench press, shoulder press and push-up due to the development of training groups, a statistically significance was found in squat and biceps curl by reason of improvement in ST3. Conclusion: As a conclusion, it can be said that 6-week strength training with different frequency applied on untrained male students has a positive effect on physical, performance and strength features.
