Evaluation of the results of the study of individual indicators of physical development, special physical fitness and sports nutrition "Power Pro" of graduates of higher education with specific training conditions, engaged in mixed martial arts and law enforcement officers In order to achieve and maintain a high level of functional and physical fitness, high sports results, and maintaining the health of those who practice, a number of pedagogical, methodical, psychological, and medical-biological aspects are necessary. Therefore, the introduction of specialized sports nutrition is expedient. With the rational development of nutrition schemes, it is possible to increase the performance of athletes, improve all necessary indicators and planned results. The purpose of the article is to develop a program and recommendations for optimizing sports nutrition "Power Pro" and research the impact of specialized nutrition on individual anthropometric, indicators of general and special physical fitness of graduates of higher education with specific training conditions, engaged in mixed martial arts and law enforcement officers. The experiment involved young men (average age 19.10±0.74), high school graduates with specific training conditions, engaged in mixed martial arts and law enforcement officers (Dnipropetrovsk State University of Internal Affairs), who were divided into 2 groups – control (n= 15) and experimental (n=15). The purpose of using specialized sports nutrition was as follows: 1. Increasing both general and special fitness (training and competition). 2. Preventive action of possible injuries and disruption of adaptation. 3. Timely and correct recovery of the body of those who are engaged, after a state of overstrain. 4. Providing the body of those who are struggling with food substances, taking into account individual energy consumption. To test the developed program for the introduction of specialized sports nutrition, before and after the experiment, the following parameters were studied: height, weight, dynamometers, VL, impact force. We have developed and implemented schemes for the ratio and combination of food substances: whey protein, BCAA (branched chain amino acids), creatine, taurine, a complex of vitamins and minerals. When developing the program of specialized sports nutrition "Power Pro" for the experimental group, the main factors such as age characteristics and body weight, gender of the test subjects, as well as individual characteristics of their physical development, specifics of the sport were directly analyzed. The obtained results of the study showed a statistically significant improvement of individual anthropometric and indicators of special physical fitness in the experimental group (p<0.05). This makes it possible to draw conclusions about the positive dynamics of the implemented program of specialized sports nutrition on the monitored indicators, which are basic for athletes specializing in mixed martial arts.

A Study of Blood Pressure and Physical Fitness in People with Intellectual Disabilities in South Korea.

Individuals with intellectual disabilities have a shorter lifespan and significantly higher prevalence of conditions such as hypertension and cardiovascular diseases than healthy individuals. Thus, assessing the elements that contribute to their physical fitness is crucial. This cross-sectional study examined the relationship between the blood pressure and physical fitness of people with intellectual disabilities in South Korea, considering differences across sexes, age groups, physical attributes, and disability levels. It used data from 8502 individuals with intellectual disabilities aged 20-59 years who participated in a survey of a National Fitness Standard Center (NFSC) between 2018 and 2021. A series of t-tests, one-way analysis of variance, logistic regression, and the four-quartile method were used for data analyses. The results showed differences in physical fitness levels between men and women considering all aspects except for BMI (Body Mass Index), with men showing higher blood pressure levels. Lower grip strength, lower PEI (physical efficiency index) scores, and higher BMI were associated with increased blood pressure. Additionally, individuals with higher levels of disability tended to have lower levels of physical fitness, while higher physical fitness levels were associated with lower blood pressure. Therefore, low fitness levels and hypertension risk may be important health indicators for people with intellectual disabilities.

Physical fitness of youth students and state of readiness for military service

Among the main state tasks of improving the physical education system, experts single out the orientation of the programmatic and normative foundations of the physical education system of different age groups of the population. Physical fitness and readiness of schoolchildren for military service is a very relevant issue not only in the discussed and mechanisms of action. In the context of our state, the physical training of schoolchildren today is primarily the ability of citizens to protect, defend the territorial integrity of Ukraine and ensure the borders defined by international law. The presented vision regarding the physical fitness of its members and the model of physical fitness of student youth. The preparation of youth for military service is emphasized on the following points: in modern conditions, the preparation of Ukrainian citizens for military service is one of the main directions of state policy, and therefore the preparation of youth for the defense of the Motherland remains one of the factors of strengthening the state's defense capability; Currently, there is a positive trend in the attitude of citizens towards the need for initial military physical training in general educational institutions. This indicates the need to strengthen military-patriotic work with students; in the conditions of an increase in military personnel who serve under a contract, as well as a reduction in the terms of service under the draft, the question of the mobilization reserve often arises.

Association of Dietary Fiber and Measures of Physical Fitness with High-Sensitivity C-Reactive Protein.

Dietary fiber intake and physical fitness are independently associated with high-sensitivity C-reactive protein (hs-CRP) levels. Nevertheless, the association between dietary fiber intake, measures of physical fitness, and hs-CRP levels has not yet been fully evaluated. We investigated the influence of a combination of dietary fiber intake and measures of physical fitness, including hand grip strength, resistance training, and metabolic equivalents of tasks, on hs-CRP levels. Data collected from the Korea National Health and Nutrition Examination Survey (KNHANES) spanning 2015 to 2018 were used in this study. A total of 16,934 participants (7434 men and 9500 women aged ≥19 years) were included in this study. After adjusting for confounding factors (age, education, income, marital status, smoking status, drinking habits, total energy intake, and aerobic physical activity), we employed a multivariable logistic model to examine the association of dietary fiber intake and measures of physical fitness with hs-CRP levels. Among women, the odds of high hs-CRP levels were lower in those with the highest dietary fiber intake and superior grip strength compared to in women with the lowest dietary fiber intake and weaker grip strength (odds ratio [OR] = 0.40, 95% confidence interval [CI] = 0.24-0.68). The highest dietary fiber intake who participated in resistance exercise at least three times per week had a reduced odds of high hs-CRP levels compared with those with the lowest dietary fiber intake who did not engage in resistance exercise in both men and women (OR = 0.53, 95% CI = 0.32-0.89; OR = 0.40, 95% CI = 0.19-0.84, respectively). Our findings indicate that dietary fiber intake and high levels of physical fitness were associated with reduced odds of elevated hs-CRP levels.

Motivation of cadet’s higher military educational institutions regarding their improvement physical preparation

In the conditions of the legal regime of martial law in Ukraine, the issue of improving the physical fitness of future officers of the Security Service of Ukraine is gaining particular relevance. For cadets during the entire period of study at higher military educational institutions of the Security Service of Ukraine, the disciplines "Special physical training" and "Physical training" are an integral part of their professional training, the purpose of which is to ensure the training of specialists of the Security Service of Ukraine with a high level of physical fitness , able to withstand physical, mental, neuropsychological loads, effectively solve official tasks without reducing the efficiency of professional activity. Therefore, based on the specifics of the war on the territory of Ukraine, there is a need to improve the system of physical training of cadets of higher military educational institutions of the Security Service of Ukraine. In connection with this, it is important to form knowledge and practical skills in cadets, to lead a healthy lifestyle, to optimize movement regime and physical training, which should contribute to maintaining high combat capability of future officers of the Security Service of Ukraine. The analysis of literary sources devoted to this problem shows that a special place in the psychological provision of physical training is occupied by motivation, which prompts a person to engage in physical culture and sports. In order to determine the motivation of cadets of higher military educational institutions for physical training classes, an anonymous questionnaire survey was used. Using the questionnaire developed by him, a sociological survey of cadets was conducted. Based on the questionnaire data of the first and fifth year cadets, the ways and directions of increasing their physical fitness have been determined, which will be useful for specialists in special physical training, physical training and physical education.

Longitudinal Evaluation of Physical Fitness in Adults with Cystic Fibrosis in the Era of CFTR-Modulating-Therapies

ABSTRACT Purpose: Maintaining physical fitness plays an important role in the management of people with cystic fibrosis (pwCF). Longitudinal data on the course of physical fitness and the potential impact of the introduction of highly effective CFTR modulator therapy with elexacaftor/tezacaftor/ivacaftor (ETI) in adult pwCF are scarce. Methods: Health-related and skill-related components of physical fitness were assessed using an incremental cycle test (Wpeak), plus forward bend (FB), prone bent knee hip extension (HE), plank leg raise (PLR), standing long jump (SLJ), and standing on one leg (OLS). Relevant disease-specific clinical data (body mass index [BMI] and forced expiratory volume in 1 second [FEV1]) were recorded. Results: Twenty-eight adult pwCF (age 26.0 ± 7.8 years) were followed over 5.6 ± 0.9 years; 21 started ETI therapy during this period. Significant improvements from baseline were noted in BMI (p < 0.001) and health-related fitness components (HE, p = 0.002; PLR, p = < 0.001), whereas Wpeak and FB remained stable over time (all p > 0.05). Skill-related components (SLJ, OLS) showed no change (all p > 0.05). Subgroup analysis revealed significant improvements in BMI, FEV1, and health-related fitness measures of muscular strength and endurance (HE, p = 0.009; PLR, p < 0.001) only in pwCF using ETI. Conclusion: Despite the improvements, the impact of ETI on the individual parameters was small. Other factors than implementation of ETI alone need to be considered on the way to a high level of physical fitness in adult pwCF.

Alterations of the gut microbiome are associated with epigenetic age acceleration and physical fitness.

Epigenetic clocks can measure aging and predict the incidence of diseases and mortality. Higher levels of physical fitness are associated with a slower aging process and a healthier lifespan. Microbiome alterations occur in various diseases and during the aging process, yet their relation to epigenetic clocks is not explored. To fill this gap, we collected metagenomic (from stool), epigenetic (from blood), and exercise-related data from physically active individuals and, by applying epigenetic clocks, we examined the relationship between gut flora, blood-based epigenetic age acceleration, and physical fitness. We revealed that an increased entropy in the gut microbiome of physically active middle-aged/old individuals is associated with accelerated epigenetic aging, decreased fitness, or impaired health status. We also observed that a slower epigenetic aging and higher fitness level can be linked to altered abundance of some bacterial species often linked to anti-inflammatory effects. Overall our data suggest that alterations in the microbiome can be associated with epigenetic age acceleration and physical fitness.

METHODS OF CONDUCT OF A FORMAL EXPERIMENT FOR STUDYING THE STATE OF FORMATION OF THE PHYSICAL READINESS OF FUTURE OFFICERS FOR MILITARY-PROFESSIONAL ACTIVITIES

The article presents the results of the formative stage of the pedagogical experiment and a statistical analysis of its results in terms of the formation of physical readiness of future officers for military and professional activities.&#x0D; The analysis of feedback from graduates - officers of the Land Forces (hereinafter - AF) - revealed that 20% of the feedback contains information about the low level of physical fitness and readiness of young officers for military and professional activities. This necessitates more effective contextual approaches to the development of physical qualities and military-applied physical skills and combat abilities of future officers of the Land Forces (hereinafter - future officers) as subjects of military management.&#x0D; It is found that an officer, as the main figure in the organization and conduct of hostilities, must meet the requirements of modern hybrid warfare. At the same time, its experience demonstrates that officers are required to have a high level of physical fitness and readiness for military and professional activities.&#x0D; The methodology for conducting physical training with future officers has been improved, which should be carried out primarily taking into account the loads adequate to the conditions of their future combat activities and through its pedagogical modeling in accordance with the peculiarities of military and professional activities in combat conditions.&#x0D; It has been experimentally determined that the methodology of physical training of the experimental group (hereinafter - EG) demonstrated effectiveness, which allowed to increase the level of their physical fitness in the power complex by 15.05%, while in the control group (hereinafter - CG) such an increase was only 3.1%. The functional state of future officers also changed positively. The level of the studied scales improved by an average of 15.6% in the EG, and by 7.2% in the CG. Improvements in the running complex were not so obvious and amounted to 2.7% in the EG and 1.5% in the CG. This may indicate that the improvement of speed (both on short and long distances) is very slow and requires more intense, intensive, specially directed work.&#x0D; The results obtained during the experiment allow us to assert that the level of physical readiness of the EG is good and allows it to successfully perform the assigned combat tasks.

Fat but Fit: How physical fitness can mitigate the cardiovascular risks of obesity?

Obesity has long been recognized as a major independent risk factor for cardiovascular diseases (CVD). However, intriguing paradoxes such as the "obesity paradox" and the "fat but fit" phenomenon have been associated with it. The "fat but fit" paradigm suggests that overweight or obese individuals might face a lower risk of developing cardiovascular disease if they possess high levels of physical fitness. In other words, higher fitness levels may mitigate the negative impact of obesity on cardiovascular risk, leading to a reduction in overall mortality due to CVD. The evidence surrounding this paradox is conflicting, highlighting the necessity for further research. The complex relationship between physical fitness, obesity, and cardiometabolic health is influenced by individual and environmental factors. Consequently, it becomes imperative to conduct more studies to comprehend this intricate interplay fully. To address this issue, it is important to focus on formulating strategies that promote the maintenance and enhancement of cardiorespiratory fitness in overweight and obese individuals. Moreover, including fitness evaluations in comprehensive risk stratification can significantly improve clinical decision-making.

Associations Between Physical Fitness, Cognitive Function, and Depression in Nursing Homes Residents Between 60-100 Years of Age in South-Western Poland.

BACKGROUND Healthy aging depends on physical fitness, cognitive function, and emotional well-being. Reduced physical activity in the elderly impacts daily activities, increasing morbidity risk. Cognitive decline affects learning, attention, and independence. Depression, prevalent among the elderly, correlates with loneliness and affects overall health. Physical fitness positively influences cognitive health and mood. This study examines these associations in Polish nursing homes residents. MATERIAL AND METHODS We assessed 93 people aged 60-100 years living in nursing homes. The Short Physical Performance Battery (SPPB) test was used to assess physical fitness. The Abbreviated Mental Test Score (AMTS) was used to assess cognitive functions. The Geriatric Depression Scale (GDS) was used to assess depression. RESULTS In the SPPB test, the mean score was 4.85 points, indicating moderate limitations. On the AMTS, 55% of subjects had cognitive impairment. On the GDS scale, 44% of respondents had depressive symptoms. Seniors without mood disorders were characterized by faster gait compared to those with suspected depressive disorders (P=0.036). Men performed significantly better in the whole SPPB test (P=0.024) and in the standing up from a chair and gait speed tests (P=0.046, P<0.001) compared to women. We found a negative correlation between the AMTS test scores and the SPPB gait test scores and age (P<0.05) and a positive correlation between the SPPB gait test scores and the GDS scores (P<0.05). CONCLUSIONS Older nursing homes' residents in better emotional and cognitive state tended to have faster gait. Men tended to have a higher level of physical fitness compared to women. Older age was associated with worse cognitive state of the examined seniors.

Association between nutritional status, body composition, and fitness level of adolescents in physical education in Casablanca, Morocco.

This study aims to analyze and compare dietary intake, as well as to examine the associations between energy intake in terms of macronutrients, body composition, and physical fitness (PF) specifically cardiorespiratory endurance (CE) among a sample of young adolescents aged 15 to 18 years, who participate in physical education and sports sessions in public schools in Casablanca, Morocco. A total of 311 participants, including 156 girls and 154 boys, were included in the study. Each participant maintained a food diary for 3 days during the same study week. Additionally, body composition measurements were taken using bioelectrical impedance analysis (BIA). The PF was assessed using the validated mini-Cooper test (6 min). The results show that the participants had an average total energy intake of 2386.7 ± 492.7 kcal. A significant difference was observed between boys and girls, with average energy intakes of 2468.8 ± 531.1 kcal and 2304.0 ± 437.0 kcal, respectively. These dietary intakes were significantly lower than their needs and nutritional recommendations. The associations of nutritional status, sex, body mass index (BMI) and physical fitness (PF) were tested and a positive correlation was observed following an adequate intake of carbohydrates (CHO) and proteins on Vo2max, while a negative association was observed with regard to Body fat for both sexes. Boys exhibit significantly better PF than girls (p < 0.01). Obese participants had the lowest PF and an unbalanced nutritional status, the adolescents with a normal weight p < 0.01 displayed a high level of PF compared to individuals in other weight categories. The PF is significantly associated with macronutrient intake status and body composition, especially BMI and BF. The Underweight, overweight, and obese students demonstrated poorer performance in physical fitness indices compared to normal-weight. Adolescents adhering to recommended CHO and protein intake levels tend to exhibit enhanced physical fitness. Implementing strategies to encourage students to maintain a balanced diet and engage in regular physical exercise is essential.

The Football Players on Plyometric Exercise: A Systematic Review

Achieving peak performance in sports necessitates athletes having a high level of physical fitness. Among the key physical components, both overall fitness and movement fitness play significant roles in competitive sports, particularly those involving muscles. Football, a globally popular sport, demands explosive movements like kicking, tackling, jumping, sprinting, and rapid changes in direction. Training effectiveness is crucial for attaining success in football matches. This paper focuses on investigating studies that utilize plyometric training to enhance football performance. In order to search for articles, using the keywords plyometric training, physical fitness, performance football by using database from Google Scholar, PubMed Central, and Science Direct. 13 articles were obtained and analyzed from 2013 to 2022. Search results were arranged based on the format of P (Population), I (Intervention), C (Comparison), O (Outcome). A review of 13 articles concluded that there was an improved level of agility, speed, strength, explosive power, physical fitness, aerobic endurance, acceleration power, on the physical performance of football players. The goals and demands of each training session must be adapted through plyometric training, and each exercise can then be performed regularly to reduce the possibility of injury. Based on the results of the review, plyometric training has been extensively studied to understand its impact on football players. The training program, lasting 6-10 weeks with 2-3 sessions per week, can enhance physical performance by increasing explosive lower body strength, specific physical abilities, and endurance. Plyometric exercises come in different intensity levels, such as low, moderate, and high, and positively affect leg strength, explosive speed, power, aerobic capacity, body composition, flexibility, and muscle endurance in elite athletes and can be customized to target specific goals like speed or strength enhancement, benefiting football players.

Determination of 15 Functional State Biomarkers in Human Urine by High-Performance Liquid Chromatography with Tandem Mass Spectrometric Detection

The capabilities and limitations of complex procedures for targeted metabolomic analysis using liquid chromatography in combination with tandem mass spectrometry (HPLC-MS/MS) are discussed. An HPLC-MS/MS procedure for the simultaneous determination of the concentrations of 15 biomarkers of the functional state of a human being in urine is presented. The target analytes are biogenic substances of various chemical natures, the basic concentrations of which in biomatrices can vary significantly, up to three orders of magnitude or more. Complex analysis is also difficult to perform due to significant differences in the hydrophilic and hydrophobic properties of the analytes. The testing of the procedure in a bioanalytical experiment made it possible to establish significant differences in the concentrations of a number of biomarkers in the urine of persons with different levels of physical fitness. With a high level of physical fitness, the concentrations of these compounds in urine have lower values in comparison with those in the control group.

ELECTROENCEPHALOGRAPHIC MARKERS OF CNS FUNCTIONAL STATE IN SPORT

All over the world, sports professionals are interested in attracting new technologies to work-out sessions to increase sportsmanship. Literature reveals that EEG markers of cognitive function dynamics, sensorimotor integration, and psychological stability are important in assessing the functional state of athletes. In addition to a high level of physical fitness, elite athletes develop cognitive skills specific to a particular sport. Besides they demonstrate high sensorimotor integration, improved attention, perception and information processing and other characteristics ensuring high performance. The review systematically analyzes publications devoted to the correlation between physical activity and CNS functional state. It is established that indicators of EEG alpha rhythm power and frequency are significant neurophysiological markers of cognitive function state. These indicators contribute much to studying high- and low-intensity physical activity.&#x0D; The authors analyzed such databases as Medline, Web of Science, Scopus, Pubmed, Cochrane, Embase, Google Scholar, and eLIBRARY.
