The purpose of study was to develop and to substantiate experimentally the efficiency of the 8-week model of the stage of direct training for main competitions of highly qualified multi-sport athletes in track-and-field athletics. Material and Methodology. 5 highly qualified multi-sport athletes having a sports qualification of the Master of Sports of Ukraine took part in the pedagogical experiment. The average age of the participants was 25.2±1.79 years. The technological basis for introduction of combined events competitions of track-and-field athletes into the requirements of the 8-week model of the phase of direct training for main competitions was constituted by: an algorithm of the individual program for training multi-sport athletes for competitions, which reflects the consistency of actions for the purpose of preparing the athletes to perform given tasks; programming of the training process, which shows the directions of performance of tasks during specific mesocycles while taking into account the feasibility of the development of components of technical and physical preparedness and types of combined events competitions in track-and-field athletics; structuring the process of straining and recovery, which determines the permissible levels and intensity of training loads during separate sessions and microcycles. Results. We reduced the magnitude of training loads (up to 3233 min) and increased their intensity (up to 6.51 points·min-1) during the forming experiment at the phase of direct training for competitions, which allowed to achieve peak sports form and evoke additional resources in the organism of athletes. The introduction of the developed 8-week model of the direct training stage contributed to a statistically significant improvement in the indicators of physical preparedness of the studied multi-sport athletes in running tests by 2.3-3.1%, while it made 4.4-4.9% in the tests representing speed and strength qualities and 4.5-4.9% in strength control exercises (p < 0.05). The improvement of the results of most disciplines in the range of 1.7-5.3% (p < 0.05) confirms the efficiency of the developed 8-week model of the phase of direct training. Conclusions. Solution of specific tasks during final weeks before the main starts requires the establishment of optimum volumes of training work and load dynamics, combining training sessions with training loads of various orientation and magnitude, using rest and recovery means as a whole complex, ensuring operative and current control over the course of recovery and adaptation processes. Taking the aforementioned problems into account, we have developed an 8-week model at the phase of direct training for competitions, in which three mesocycles were determined with strictly defined tasks and corresponding training content.

Aim of study. Cricket is considered a mental game among elite level performers. Specific personality traits characterize elite-level endeavors and high-potential athletes. Previous studies on psychological characteristics of cricket players reported that more skilful cricketers deal more consistently and effectively with their emotions and pressure. Therefore the objective of the present study was analysis of personality traits of cricket players at national, state, and district levels with the help of Five-Factor Model. Materials and Methods. Sample size included 120 male subjects (60 batsmen and 60 pace bowlers) recruited from cricket academies/training facilities/competition venues in India. Big-Five Personality Inventory (BFI-44) was utilized to measure personality dimensions. Differences among personality variables at different competition levels of batsmen and pace bowlers were analyzed using One-way MANOVAs. Results. National level pace bowlers scored high on openness (national vs. district, Mean Difference (MD) = 4.25, p < 0.05; national vs. state, MD = 2.75, p < 0.05) and agreeableness (national vs. district, MD = 4.70, p < 0.05; national vs. state, MD = 3.40, p < 0.05). Similarly, national level batsmen scored high on extraversion (national vs. district; MD = 4.350; p < 0.05), agreeableness (national vs. state; MD = 3.70; p < 0.05), and conscientiousness (national ns. district, MD = 3.25, p < 0.05; national vs. state, MD = 3.450, p < 0.05). Conclusions. National level pace bowlers exhibited greater agreeableness and openness whereas similar level batsmen showed greater agreeableness, openness, extraversion, and conscientiousness as compared to lower levels of participation. Since the concept of “Form” demands multi-factorial approach in the game of cricket, other facets of personality such as focus, mental toughness, self-belief, optimism etc. should also be explored for effective talent identification and coaching in cricket.

The aims of the study were: 1. To analyse the discriminative power of neuromuscular components for classifying the pre and post muscle fatigued states. 2. To examine whether the modification of neural recruitment strategies become more/less heterogeneous due to fatigue. 3. To research the effect of Erector Spinae (ES) muscle activity collectively with Rectus Abdominis (RA) and External Oblique (EO) muscle activity to identify the reduced spine stability during fatiguing Plank. Material and methods. Twelve boys (age – 12-14 years, height 148.75 ± 10 cm, body mass 38.9 ± 7.9 kg) participated in the study. Multivariate Discriminant Analysis (DA) and Principal Component Analysis (PCA) were applied to identify the changes in the pattern of the electromyographic signals during muscle fatigue. In DA the Wilks’ lambda, p-value, canonical correlation, classification percentage and structure matrix were used. To evaluate the component validity the standard limit for Kaiser-Meyer-Olkin (KMO) was set at ≥0.529 and the p-value of Bartlett’s test was ≤0.001. The eigenvalues ≥1 were used to determine the number of Principal Components (PCs). The satisfactory percentage of non-redundant residuals were set at ≤50% with standard value >0.05. The absolute value of average communality (x̄ h2) and component loadings were set at ≥0.6, ≥0.4 respectively. Results. Standardized canonical discriminant analysis showed that pre and post fatigued conditions were significantly different (p = 0.000, Wilks’ lambda = 0.297, χ2 = 24.914, df=3). The structure matrix showed that the parameter that correlated highly with the discriminant function was ES ARV (0.514). The results showed that the classification accuracy was 95.8% between fatigued conditions. In PCA the KMO values were reduced [0.547Pre fatigue vs. 0.264Post fatigue]; the value of Bartlett’s sphericity test was in pre χ2 = 90.72 (p = 0.000) and post fatigue χ2 = 85.32 (p = 0.000); The Promax criterion with Kaiser Normalization was applied because the component rotation was non-orthogonal [Component Correlation Matrix (rCCM) = 0.520 Pre fatigue >0.3Absolute<0.357Post fatigue]. In pre fatigue two PCs (cumulative s2 – 80.159%) and post fatigue three PCs (cumulative s2 – 83.845%) had eigenvalues ≥1. The x̄ h2 increased [0.802 Pre fatigue vs. 0.838 Post fatigue] and the percentage of nonredundant residuals reduced [50% Pre fatigue vs. 44% Post fatigue] from pre to post fatigue. Conclusions. The variability and heterogeneity increase in the myoelectric signals due to fatigue. The co-activity of antagonist ES muscle is significantly sensitive to identify the deteriorating spine stability during the fatiguing Plank. Highly correlated motor unit recruitment strategies between ES and RA, providing supportive evidence to the concept of shared agonist-antagonist motoneuron pool or “Common Drive” phenomenon during fatigue.

The purpose of the article is to study prerequisites for the development of preventive measures against office syndrome among women of working age. Material and methods. The research involved 52 female office employees 21 to 57 years old. Results. The extended clustering of the original data using EM method with the performance of V-fold crosschecking has shown that female office employees are clearly divided into two clusters depending on the manifestation of office syndrome. Despite our assumptions, their division does not depend on age or length of service in the office, but on the manifestation of office syndrome and behavioral characteristics in the work process. Women assigned to different clusters are characterized by statistically significant (p < 0.05) differences between the level of pain in the joints and spine. The research has found that among female office employees with increased musculoskeletal pain, there are statistically significantly (p<0.05) more women with significant overweight and spinal diseases. They are less likely to take active breaks when working at a computer and a larger percentage of them use information technology for entertainment purposes outside the office for 3-4 hours a day. However, a smaller percentage of them work with a PC for more than 7 hours a day. Women with predominant musculoskeletal pain differ in their lifestyle and point to fundamentally different reasons that stop them from taking measures to prevent the risk of occupational diseases. In particular, among female office employees with no office syndrome, a statistically significant (p<0.05) larger share does not need to expand knowledge about the organization of health care in the office and among them the share of those who lead a passive lifestyle predominates. Conclusions. Thus, these women are potentially at risk of developing office syndrome and, with the absence of preventive measures, are expected to move to the cluster of women with signs of office syndrome. The results of the research indicate the need for different approaches to planning health measures in the work environment, depending on the presence of office syndrome and the level of their responsible attitude to health in the work process.

The study objective is to improve the structure and content of the annual training macrocycle for athletes aged from 15 to 16 years old in pankration, taking into account the specifics of their competitive performance. Materials and methods. Theoretical analysis and generalization were used during work with literary sources on the problems of the research. Survey (questionnaire) was used for studying general approaches to the structure and content of young athletes’ training (aged from 15 to 16 years old) in pankration. There were also analyzed official programs for experienced pankration athletes which are used in Ukraine. Pedagogical experiment was held during September 2018 – July 2019. Its total duration was 10 months and 906 hours. Two identical six-month training macrocycles were performed. The control (21 athletes) and experimental (22 athletes) groups were formed. Results. It was more effective for the development of technical and tactical actions and special physical fitness of young athletes aged from 15 to 16 years old. It was confirmed by significant intra-group increases in indicators of athletes’ preparedness (p≤0.05-0.01). The total number of significant changes in the experimental group (p≤0.05-0.01) during the first and second stages of the experiment was 12 of 13 indicators, and their values were higher than in the control group. In the control group, significant positive changes (p≤0.05-0.01) were found in 6 indicators during the first stage of the experiment and 8 – during the second one. After the second stage of the experiment athletes of the experimental group performed about half of the technical and tactical actions with a higher level of stability, economy, efficiency in various situations during sparring matches. Conclusions. An experimental program made it possible to achieve an earlier deployment of adaptation processes to the specific physical activity available in training and competitive activities in pankration.

Quality of life (QL) is defined as the subjective perception of one’s own well-being in a socio-cultural context, the satisfaction of one’s desires and the achievement of an ideal level of well-being. Quality of life is related to health (HRQOL), refers to the functioning and well-being in the physical, mental and social dimensions of life. Research purpose: to analyze the main factors of quality of life of male and female population in modern Ukrainian society. Material and Methods. 482 men and women aged 20-60 took part in sociological research. The following research methods were used to solve the problemsset in the work: analysis and processing of special literature and data from the Internet; pedagogical observation; questionnaires (SF36); methods of mathematical statistics. Results. The results of their own research show that the male population had a better quality of life on all scales of the SF-36 questionnaire compared to women (p <0.05). Respondents under the age of 20-29 had indicators of quality of life above average on the scales of physical and role physical functioning; pain in this age group did not have a significant impact on quality of life. The general state of health was assessed above the average level by respondents aged 20-29 and 30-39, regardless of gender, they were characterized by high scales of social activity and viability. Conclusions. It is established that the indicator General health is a system-forming factor of quality of life for men and women in terms of the number of correlations. The obtained results allowed to determine the expediency and speed of implementation of preventive measures for men and women depending on the content of certain scales. Decreased overall health (GH) in men and women after the age of 50 significantly affects their quality of life, as evidenced by the large number of significant correlation coefficients. In women over 50 years of age, there is a sharp decrease in RP (role functioning due to physical condition) to 46 points, vital activity (VT) to 50 points, role functioning (due to emotional state) (RE) to 53 points. In men at this age, role functioning increases to 90 points, and social functioning (SF) to 89 points, which may indicate an uneven distribution of family and social functions in the lives of people of different sexes, overloading women with household chores, which prevents them from spending free time, affects the emotional state.
