The Benzodiazepine and Opiate Withdrawal Service: an overview and case studies
Authors: Fernandez Jeff
Published: March 2020

Patients who have a dependency on benzodiazepines and nonbenzodiazepines have always been able to access drug services in the past in primary care. This has now been expanded to include other problematic drug use on mainly prescribed medications, such as tramadol, gabapentin and pregablin, with the development of the Benzodiazepine and Opiate Withdrawal Service across Camden and Islington. This article looks at the population in general practice in Islington who have been on codeine-based medications for a long time. It examines how treatment can be changed and made more beneficial for them with engaging in specialist services supporting GPs in primary care.
Coenzyme Q10 supplementation in non-alcoholic fatty liver disease: an overview
Authors: Mantle David , Hargreaves Iain P
Published: March 2020

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in the UK, for which little effective conventional treatment is available. Mitochondrial dysfunction, oxidative stress and inflammation have been implicated in the pathogenesis of NAFLD. This article focuses on the role of the vitamin-like substance coenzyme Q10 (CoQ10) in NAFLD, since CoQ10 plays a key role in mitochondrial function, as well as having antioxidant and anti-inflammatory action. CoQ10 levels are depleted in NAFLD, and studies in animal models and human subjects have indicated that supplementation with CoQ10 can significantly reduce oxidative stress and the inflammation characteristic of NAFLD. In addition, NAFLD patients are at increased risk of developing heart failure, and supplementary CoQ10 may help to reduce this risk. Supplementary CoQ10 is generally well tolerated, with no significant adverse effects reported in long-term use.
Early identification of dehydration with orthostatic blood pressure monitoring in high-output ileostomy patients
Authors: Edwards Dani Marie , Sell Laura Ruth
Published: March 2020

Background:

High readmission rates among ileostomy patients are often the result of dehydration, but this can be prevented with prompt intervention.

Aim:

This study aimed to determine whether a combination of close follow up and obtaining orthostatic blood pressure would lower 30-day readmission rates in ileostomy patients.

Method:

Colorectal patients with newly formed ileostomies were enrolled in a surgical transitional care programme. Those with high-output ileostomies were offered education on taking their orthostatic blood pressure at home, and registered nurses completed follow up via telephone.

Findings:

From December 2017 to April 2019, 171 ileostomy patients were enrolled in a surgical transitional care programme. Of these, 27 patients were provided with orthostatic blood pressure instruction. Readmission rates for the orthostatic blood pressure group were 7.4%, compared with 15.3% in all other ileostomy patients enrolled in surgical transitional care.

Conclusion:

Orthostatic blood pressure monitoring in high-output ileostomy patients may help to reduce 30-day readmissions.
Knowledge and competencies regarding artificial nutrition among ward nurses and doctors: results of a pilot questionnaire
Authors: Rogers Naomi
Published: March 2020

Background:

Ward staff often lack basic nutritional knowledge in the care of artificially fed patients. Clinical guidelines and training aim to improve nutritional perceptions and maintain patient safety.

Aim:

To evaluate the level of nutritional knowledge and competencies among ward staff and improve the standard of teaching available to healthcare professionals.

Method:

A staff questionnaire was piloted to measure content validity and evaluate study objectives. Nine questions were thought to be essential standards in the care and management of both enteral and parenteral patients. Four multiple-choice and five open-ended questions were used.

Results:

A 100% response rate was achieved from nine nurses and one doctor. They had been qualified for an average of 3.3 years (range 1–6, median 2), and their nutritional knowledge was defined as acceptable.

Conclusion:

Guidelines and recommendations were not being implemented, and nutritional care of patients was a low priority. Health professionals need to be more aware of the role of the nutrition support team to prevent role ambiguity.
Gastrointestinal symptoms of pelvic radiation disease (part 1): literature review
Authors: Ludlow Helen , Green John
Published: March 2020

Radiotherapy used to treat cancers in the pelvic region can have lasting side effects, and the persistence of these symptoms for 3 months or more is described as pelvic radiation disease (PRD). The growing number of pelvic cancer patients being diagnosed and successfully treated is increasing the incidence of PRD. This review examines the literature on the gastrointestinal symptoms of PRD. This includes how PRD is defined, how it is identified and how it relates specifically to the three pelvic cancers in which it most commonly manifests (prostate, gynaecological and colorectal). It pays particular attention to the impact of PRD on patient experience and quality of life. This review is the first part in a series on the GI symptoms of PRD.

Authors: Harris Richard J , Downey Louise , McDonnell Martin , Borca Florina , Felwick Richard , Phan Hang TT , Cummings Fraser , Gwiggner Markus
Published: March 2020

Inflammatory bowel disease (IBD) clinical nurse specialists deliver a service that is highly valued by patients. Access to a specialist nurse-led IBD helpline forms part of the UK IBD consensus standards. This retrospective cohort study analyses the workload evolution of an IBD helpline and discusses its implications for the design of future services. Helpline activity was shown to increase significantly between 2016 and 2018. While largely due to appropriate increased patient demand for acute advice, significant inefficiencies were demonstrated. These are likely to be present in other comparable helpline services, alongside opportunities for making more efficient use of specialist nurse time. In addition, helpline activity was shown to generate a significant additional workload involving patient follow-up and results. Robust methods for capturing this workload could help units with similar services with service design, job planning and reimbursement.

An Electrohydraulic Pressure Compensation Control System for an Automotive Vane Pump Application
Authors: Jenkins Ryan Paul , Ivantysynova Monika
Published: March 2020

Pressure compensated vane pumps are an excellent solution for supplying hydraulic power with minimal waste in many automotive applications. An electrohydraulic pressure compensation control system for an automatic transmission supply that promises improved pressure response times over the baseline architecture is discussed. Suggested valve specifications are determined through calculations based on available data and refined via a validated simulation model of the proposed system. Two controller designs are formulated and compared: a basic PI control law and a cascaded model following controller including a nonlinear feedback linearization component. Simulations of the proposed system for a given duty cycle reveal that the nonlinear controller provides only minor improvements over a basic PI control law and is thus not an economical solution.

The Australian New Zealand Intergenerational Cohort Consortium (ANZ-ICC) brings together three of the longest running intergenerational cohort studies in Australia and New Zealand to examine the extent to which preconception parental life histories (from infancy to parenthood) predict next generation early health and development. The aims are threefold: (1) to describe pathways of advantage that strengthen emotional health and well-being from one generation to the next, (2) to describe pathways of disadvantage that perpetuate cycles of emotional and behavioural problems across generations, and (3) to identify modifiable factors capable of breaking intergenerational cycles. The Victorian Intergenerational Health Cohort Study has followed 1,943 young Australians from adolescence to adulthood across ten waves since 1992, and 1,030 offspring from pregnancy to early childhood since 2006. The Australian Temperament Project Generation 3 Study has followed 2,443 young Australians from infancy to adulthood across 15 waves since 1983, and 1170 offspring from pregnancy to early childhood since 2012. The Dunedin Multidisciplinary Health and Development Study Parenting Study has followed 1,037 young New Zealanders across 15 waves since 1972, and 730 offspring in early childhood since 1994. Cross-cohort replication analyses will be conducted for common preconception exposures and next generation offspring outcomes, while integrated data analysis of pooled data will be used for rare exposures and outcomes. The ANZ-ICC represents a unique collaboration that bridges the disciplines of lifecourse epidemiology, biostatistics, developmental psychology and psychiatry, to study the role of parental preconception exposures on next generation health and development.
Realization of an all-optical comparator using beam interference inside photonic crystal waveguides
Authors: Jile HuGe
Published: March 2020

Using optical beam interference inside photonic-crystal-based waveguides is a promising method for designing and realizing all-optical logic gates and other digital devices. In this paper we design and propose an all-optical 1-bit comparator using optical beam interference. In the proposed structure, the logic states of input ports are determined based on their initial phases. The 180 deg and 0 deg phases are used as logic 0 and 1. However, the logic states of the output ports are determined based on the amplitude of the optical signal at the output ports. For the proposed structure, the maximum rise and fall times are about 0.6 ps and 0.3 ps, respectively.
Radial and tangential velocity effects of a probed scanning mirror on laser Doppler frequency shift
Authors: Agusanto Kusuma , Lau Gih-Keong , Liu Ting , Zhu Chuangui
Published: March 2020

A laser Doppler vibrometer (LDV) is precise and fast in measuring the translational velocity of a vibrating diffuse surface. However, it could fail to measure the tangential velocity of a rotating mirror. While the specular reflection away from the mirror can be recovered by a retroreflective collector, the recovered LDV reading is found to deviate from the true tangential velocity of the probed scanning mirror. This happens because the probed spot shifts radially along the rotating mirror surface and thus introduces extra Doppler shift, while the laser beam is aimed at a constant height on the scanning mirror. Here, we derive an analytical relationship between the laser Doppler shift and the tangential velocity of the measured spot. With the input of the prescribed scan profile, we recover the true reading of tangential velocity of the scanning mirror even at a large rotational angle. This corrected LDV reading is as precise as the measurement by a high-speed camera.
Scintillation averaging and fade statistics
Authors: Shaw Scot E. J.
Published: March 2020

This work develops expressions for the variance and power spectral density (PSD) of atmospherically induced amplitude fluctuations of a propagating beam of light, also known as scintillation. This extends a recently published analytic approach for atmospheric propagation studies, previously applied to the phase properties of a propagating beam. In addition to laying out the general principles for manipulating log-amplitude expressions, this work develops novel expressions for scintillation under aperture, path, wavelength, and temporal averaging, first separately and then as a unified expression. The PSD expression is then used to find several statistics of fades of given depth and duration, including fade probability, rate, and average duration. Results are shown throughout to agree with existing literature and wave-optics simulations.
Asymmetric light transmission based on a 1D triangular metal grating
Authors: Lin Yu
Published: March 2020

Here, we present a 1D isosceles triangle silver grating on the dielectric substrate. The grating performs asymmetric light transmission (ALT) characteristics for the light with both transverse magnetic (TM) and transverse electric (TE) polarization states over a waveband in the vicinity of 1.55 µm. By checking the efficiency of each diffraction order and the distribution of the electromagnetic field, we found that the ALT characteristics originate from the high transmitted or reflected diffraction channels excited by forward and backward direction incidence. The grating shows the ALT characteristics in a waveband where incident wavelengths are less and more than the period, so that the grating may be a candidate for the wideband ALT devices. It is worth stressing that the contrast ratio (CR) at a specific wavelength can exceed more than 29 dB (the incident angle is 5.6897°; the incident wavelength is 1.7759 µm) under oblique incidence.

Published: March 2020

We report the polarization preservation of quantum light in the optical systems of the terminals of the world’s first quantum communication satellite, Micius. The main scientific experimental goals and polarization requirements of the satellite and ground station are introduced firstly. Three optical terminals are equipped on Micius to achieve our scientific goals, including a quantum entanglement source (QES), quantum entanglement transmitter (QET) and quantum key distribution transmitter (QKDT), and the function of each optical terminal is described briefly. A polarization-maintaining design for the terminals on Micius is critical for quantum communication, and the optical structure of the QKDT and QET is determined by using three polarization-maintaining methods. The optical configurations of the QKDT and QET are introduced, and the polarization-maintaining methods are described in detail. The final polarization extinction ratios of the QKDT and QET at wavelengths of 850 nm and 810 nm are better than 500:1, which provides critical technical support for realizing the scientific goals of Micius.
Simple autofocusing method by image processing using transmission images for large-scale two-photon lithography
Authors: Fujishiro Yoko , Furukawa Taichi , Maruo Shoji
Published: March 2020

We propose a simple autofocusing technique that can be introduced into conventional two-photon lithography systems without additional devices. Autofocusing is achieved by image processing using transmission images of photopolymerized voxels. The signal-to-noise ratio of transmission images was improved by optimal low-pass filtering to detect voxels in them. The focal point was detected with an accuracy of about 250 nm from the difference images. Further, we demonstrated mass-fabrication of a 5 × 5 spiral square array with an area of 900 × 900 µm2 using this method. The method has potential application in constructing low-cost, compact and versatile two-photon lithography apparatus.

Published: March 2020

This Letter presents an effective crosstalk compensation method for color fringe projection profilometry. The crosstalk-induced phase error has been studied, and we find that the phase error doubles the frequency of the color fringe. Therefore, Hilbert transform is applied on the color fringe to shift the carried phase by

Simulations and experiments confirm that the proposed method can effectively suppress the crosstalk-induced phase error to improve the measurement accuracy.
Policy alignment in the European audio-visual sector: A small-market perspective from Estonia
Authors: Rohn Ulrike , Loeser Henry
Published: March 2020

The policy changes in the reform of the EU Audiovisual Media Services Directive (AVMSD) and implementation the digital single market (DSM) have recently been a major topic of debate among policy-makers and stakeholders alike. The European Commission (EC), through its various online publications, has sought to inform this discourse and promote acceptance of the reforms by communicating numerous benefits of the proposed new policy. Deploying a mixed-methods approach, our research examines the benefits of policy reform promised by EC online publications, how these proposed benefits are evaluated by industry stakeholders in Estonia, and if the two are aligned. By our definition, policy can be in alignment with industry stakeholders when it accurately addresses their values, needs and priorities. In detail, the research looks at how each of the proposed benefits aligns with what industry stakeholders in Estonia see as important for the audio-visual industry in general, important for their own professional interests, whether a policy change was needed, and finally whether they think that a policy change would be effective. Though a wealth of research can be found about the impact of policies on stakeholders, our article queries those stakeholders about their views, and addresses a perceived gap in existing research on the alignment of policy.
The impact of citizen journalism engagement in Indonesian television on citizen journalists and society: A case study of the NET Citizen Journalist (NET CJ) programme
Authors: Rastiya Asty , Hendriyani
Published: March 2020

Citizen journalism in television in Indonesia has flourished in the past decade, with two national commercial companies broadcasting citizen programme on occasion and three stations engaging in ongoing citizen journalism initiatives. This article uses a case study of Indonesia’s NET Citizen Journalist (NET CJ) programme to study perspectives of citizen journalists about the impact of citizen journalism in television on themselves and their society. Surveys and interviews with active CJ members indicated that collaboration between citizen journalists and television networks democratizes information by allowing a wider range of people to share information and perspectives, and drives positive changes in citizen’s surroundings and self-development in terms of knowledge and skills in news video production. However, potential negative side-effects are the high risk of being sued by injured parties and dissatisfaction about limited opportunities to have community videos broadcast on television.
EFFECT OF AGE AND GENDER ON ARTICULATION OF VOICED AND VOICELESS STOP CONSONANTS IN CZECH
Authors: Kaňok Martin , Novotný Michal
Published: March 2020

Evaluation of precision of consonant articulation is commonly used metric in assessment of pathological speech. However, up to date most of the research on consonant characteristics was performed on English while there are obvious language-specific differences. The aim of the current study was therefore to investigate the patterns of consonant articulation in Czech across 6 stop consonants with respect to age and gender. The database used consisted of 30 female and 30 male healthy participants. Four acoustic variables including voice onset time (VOT), VOT ratio and two spectral moments were analyzed. The Czech plosives /p/, /t/ and /k/ were found to be characterized by short voicing lag (average VOT ranged from 14 to 32 ms) while voiced plosives /b/, /d/ and /g/ by long voicing lead (average VOT ranged from -79 to -91 ms). Furthermore, we observed significantly longer duration of both VOT (p < 0.05) and VOT ratio (p < 0.01) of voiceless plosives in female compared to male gender. Finally, we revealed a significant negative correlation between age and duration of voiceless (r = -0.36, p < 0.05) as well as voiced VOT (r = -0.45, p = 0.01) in female but not in male participants.
Creative mentoring: A creative response to promote learning and wellbeing with children in care. A service developed by Derbyshire County Council’s Virtual School
Authors: Parker Claire
Published: March 2020

This paper offers some insight into the benefits, impacts and challenges of the ‘creative mentor’ role. It links to a social pedagogy framework, supporting practice, and draws on creative mentors’ work with children and young people living in care. It aims to inform professionals and teams around a child about the transforming nature of working with creativity – beyond the obvious external experiences. Included are descriptions of how feelings of being ‘stuck’ can be shifted through engagement in a creative activity, moving a young person to a place of wellbeing, held within the safety of a trusting relationship. It is hoped that the reader will have a better understanding of the various stages of the creative mentoring process, and will reflect on some of the challenges faced when working with vulnerable children and young people who may have suffered early trauma. This paper describes how beginning work and establishing the relationship can be nerve-wracking for both, and how the skills of creative professionals bring a new dynamic into the work. Vignettes and discussions highlight the similarities in the creative mentor’s practice to that of the social pedagogue, and reflect on concepts and processes. We hope this work will encourage more discussion about the creative mentoring experience, to add to our community of learning around creative practices in care and in education.

Objective: to analyze the provision of medical, including rheumatology, care in Kazakhstan, to study the incidence of systemic lupus erythematosus (SLE), and to develop a registry of patients with this condition.

Material and methods. The investigators analyzed the guidelines for the organization of medical, including rheumatology, care in the republic and the official statistical materials of the Ministry of Health of the Republic of Kazakhstan in the period 2012 to 2017. Articles were searched to select activity indices, organ damages and to assess the quality of life and treatment programs in order to create a registry of patients with SLE.

Results and discussion. The paper presents the basic principles of providing medical, including rheumatology, care in the republic. It gives data on the issues of providing SLE patients with medicines in outpatient and inpatient settings. It also analyzes trends in the incidence of SLE in the population of Kazakhstan in 2012 to 2017. There were 4,448 SLE patients, including 3,986 women; a comparative analysis of indicators demonstrated a 62.8% increase in the incidence of SLE from 2012 to 2017. The purpose and objectives of the registry of patients with SLE were substantiated.

Conclusion. An analysis of morbidity rates suggests that SLE remains to be significant in the republic. The incidence of SLE has been noted to increase in the period from 2012 to 2017; there is a female preponderance (89.6%). The application of the SLE registry in clinical practice will be able to improve the diagnosis of the disease in the early stage and to prevent possible complications.
A case of isolated IgG4-related lung disease in a teenager
Authors: Sokol E. V. , Vasilyev V. I. , Kokosadze N. V.
Published: March 2020

IgG4-related disease (IgG4-RD) is a rare immune-mediated fibroinflammatory disease that is characterized by the occurrence of nodules in one or more organs and proceeds in most patients with the elevated levels of IgG4 in serum and/or in the tissues of the affected organs. The majority of patients are elderly men, and the disease in most cases has a slowly progressing systemic course. The cases of isolated IgG4-related injury to the viscera, which are much less common than the systemic type of the disease, are a very difficult differential diagnosis, and biopsy of these organs is associated with technical difficulties and poses a threat to the patient's health. The paper describes just such a case. It is interesting from several points of view: firstly, a rare site (solitary pulmonary nodular lesion); secondly, clinical and laboratory features (childhood onset, no immunological abnormalities – both higher serum IgG4 levels and lower complement components).

Clinicians should remember that IgG4-RD does not always have a systemic course and characteristic serological markers. In these cases, histological verification of the diagnosis is of particular importance. If the histological pattern of a fibroinflammatory pseudotumor is identified, especially in the presence of multiple nodules, IgG4-RD should always be included in the differential diagnosis.
ANAEROBIC PERFORMANCE AND MORPHOLOGICAL DEVELOPMENT OF YOUNG FOOTBALL PLAYERS DURING THE INITIAL PREPARATION STAGE
Authors: Demidov V , Sivkov V , Nazarenko A , Demidova V , Mavliev F
Published: March 2020

Aim. The purpose of the study is to determine the morphological features and anaerobic performance of young football players. Materials and methods. 20 young football players aged 12–13 years were examined. The anaerobic performance test was carried out on a Monark 891E hand ergometer (Sweden). Physical and technical preparedness was assessed with the following pedagogical tests: the 15 m standing and crouch start running test, standing long jump, vertical jump, 30-second running, 3×10 m 3×10 m shuttle run. Hip circumference as a morphological basis of anaerobic performance of the legs was evaluated by using a measuring tape. Body length and weight were measured by standard anthropometric methods. Results. The young football players have a significant heterochrony of morphological development, which is expressed in a significant dispersion of the parameters of body weight and length. At the same time, neither actual age nor training loads are the determining factors for the demonstrated strength, but the level of morphological development (i.e. biological age), as evidenced by the correlations between the hip circumference and absolute peak power (r = 0.75, at p = 0.0001). There are no similar correlations with age (both in years and in days). Technical tests, such as basketball dribbling, basketball ball handling drill, and shuttle running with the ball, as well as basketball obstacle course did not have statistically significant differences between more or less physically developed athletes. Conclusion. The approach to differentiation of athletes according to the development of speed-strength qualities based on morphofunctional data can be used in coaching practice when working with young athletes aged 12–13 years. This will allow coaches to plan training sessions aimed not at balancing differences, but at improving the training process taking into account the individual characteristics of an athlete.
MINERAL DENSITY OF BONE TISSUE AND INDICATORS OF BONE REMODELING IN HIGHLY SKILLED ATHLETES IN THE ANNUAL TRAINING CYCLE
Authors: Nikitina K , Abramova T , Nikitina T
Published: March 2020

Aim. The article aims at studying the relationship between the mineral density of heel bone and bone remodeling in cyclistduring the annual training cycle. Materials and methods. The study involved 14 highly skilled male cyclists (cycle track, MS, MSIC) aged 20–25 years with a sports experience of 5 to 16 years. The measurements were performed in the preparatory, pre-competitive and competitive periods of the annual training cycle. Bone mineral density (BMD) was measured by the method of quantitative ultrasound densitometry (QUS) using the Achilles Express ultrasonometer (Lunar, USA). BMD was estimated as a percentage of the peak norm for a given section of the skeleton (reference norms for 20–29 years). Results. The dynamics of BMD in the annual cycle correlates with a change in bone remodeling and phosphorus-calcium metabolism. A decrease in BMD during the competitive period is associated with an increase in β-Cross Laps and a decrease in osteocalcin, alkaline phosphatase, ionized calcium and serum phosphorus. Conclusion. A decrease in BMD is associated with an increase in the activity of osteoclasts and a decrease in osteoblastic activity. Indicators of bone remodeling and phosphorus-calcium metabolism reflect the status of bone tissue and the processes of general adaptation to training loads, and can be used as markers of risk of decreased BMD. The heel bone QUS method can be used to identify athletes at risk for hypotrophic conditions.

Published: March 2020

Aim. The purpose of the article is to introduce innovative approaches to training female basketball players for responding and resolving conflict situations, reducing aggressiveness, building effective interpersonal relationships during training to achieve high results. Materials and methods. The study involved two groups of female basketball players. The experimental group (EG) consisted of 32 subjects aged 18–25 years old, members of the women's basketball teams of universities in Chelyabinsk. The control group (CG) consisted of 28 subjects of a similar age, who were part of the amateur university women's basketball teams. The study used the “Aggression Test” by L.G. Pochebut, the K. Thomas Conflict Mode Instrument (adaptation by N.V. Grishina), and the T. Leary Interpersonal Behavior Circle Personal Inventory. Statistical analysis of the results was carried out using the SPSS Statistics 17.0 program. Results. High level of aggressiveness, conflict and inadequacy of interpersonal relations in basketball players was revealed. The author’s innovative modular psychological and pedagogical program for the correction of destructive types of aggression, as well as conflict and ineffective interpersonal relationships was developed and implemented. Monitoring showed a decrease in the level of physical, emotional aggression, self-aggression. The choice of adequate strategies for behavior in the conflict was formed, which indicates the effectiveness of the program when working with athletes of basketball teams during training. Conclusion. An analysis of the data obtained indicates that after the modular psychological and pedagogical program the athletes learned to neutralize conflict and at the same time switch their aggression to neutral objects, express aggression verbally with less emotional coloring, resolve conflict situations and construct harmoniously interpersonal relationships.

Published: March 2020

Aim. The purpose of the article is to study the frequency of consumption of certain products as a factor affecting students’ health. Materials and methods. The eating habits of 97 university students (78.35% – females, 21.65% – males, average age – 23.56 ± 0.08 years) are analyzed. We used the method of estimating the frequency of consumption of the main food groups in a diet. Results. There is a lack of meat and dairy products, which leads to a decrease in essential amino acids. The fatty component of the diet is represented by vegetable oils and butter, and basically corresponds to hygienic recommendations. There is enough sources of carbohydrates (bread, cereals, pasta) in the diet. Inadequate consumption of fresh vegetables, fruitsand nuts makes it possible to predict a deficiency of microelements, vitamins, pigments, dietary fiber and other “minor” components of nutrition. Consumption of sugar, tea and coffee should be assessed as a risk factor for health. In addition to the so-called “empty calories” it significantly increases the consumption of stimulant substances. Conclusion. Students’ nutrition should be assessed as irrational. The range of basic products is not diverse. A lack of essential nutrients can be assumed. This makes it possible to talk about nutrition as a risk factor for the development of alimentary prenosological states and requires correcting diet imbalances. The approved method can be used for screening in studies on the monitoring of public health. The content of health-improvement and disease-prevention programs must necessarily include strategies for optimizing nutrition.

The empirical study of technical and tactical training conducted in 2005–2015 involved 1275 persons at the age from 10 to 72 years with musculoskeletal disorders, hearing or visual impairments. The criteria for assessing the effectiveness of technical and tactical training were diagnostic questionnaires, specialized chess tests, as well as the following psychodiagnostic techniques: the Spielberger State-Trait Anxiety Inventory (STAI); well-being, activity, mood test (“SAN”-test); The Short Form-36; the UCLA Loneliness Scale. Results. The survey revealed the actual factors hindering effective sports training: difficulties in reaching the training sites, lack of information about chess sections and Internet availability. The upward trend in the technical and tactical training (TTT) dynamics is confirmed by the growth of results due to implementing strategy and tactics – up to 31 %; the development of operational thinking – up to 25 %; recent memory – up to 27 %, evaluative function – up to 31 %. As a result of sports training 72 chess players achieved the ranks and titles of The International Chess Federation, including the title of “International Chess Grand Master”. Conclusion. The pedagogical concept realized by a set of standard and innovative means, methods, organizational forms of adaptive TTT along with psychological and pedagogical support and comprehensive supervision allows to effectively transform the intellectual potential of a chess player into a sports result.

Aim. The purpose of the article is to study the patterns of forming heart pumping function reserves in schoolchildren in the conditions of hypo- and hyperkinesia. Materials and methods. The heart pumping function was assessed with the help of Ergoracer cycle ergometer (Kettler) and the load adjusted using ERGO-KONZEPT software developed for this equipment. Reserves were established by the difference between the indicators of the heart pumping function: heart rate, stroke volume, minute blood flow at maximum load and at rest. The peculiarities of heart pumping function reserves were studied in the conditions of adaptation to different movement modes in schoolchildren aged 7–18 years. Results. It was established that heart reserves in terms of heart contractions increase with age mainly by lowering the frequency at rest. Heart reserves in terms of stroke volume and minute blood flow also increase with age, especially in trained persons. The nature of changes in the reserves of minute blood flow coincides with the pattern of changes in heart reserves in terms of stroke volume. Conclusion. The study of heart reserves allowed to find the peculiarities of changes in the chronotropic and inotropic responses of the heart, which were established as the difference between heart rate frequency, stroke volume, and minute blood flow at maximum stress and the data obtained at relative rest during adaptation to different movement modes.

Aim. The aim of the article is to establish the effect of anaerobic glycolytic performance on the functional status and cognitive efficiency in primary schoolchildren. Materials and methods. Children aged 7–8 (n = 181) and 9–10 (n = 168) years participated in the study. All children belong to the main health group. A set of indicators characterizing physiological, psychological, and behavioral aspects, as well as physical performance and motor fitness was studied. Results. During the study, anaerobic glycolytic abilities of the body were considered as one of the main characteristics of physical performance in children aged 7–8 and 9–10 years. It was established that the functional status of children aged 7–8 and 9–10 years during quiet wake and under information load depended on the level of anaerobic glycolytic abilities. Using the data obtained with the analysis of variance it was found that anaerobic glycolytic abilities provided a statistically significant effect (p < 0.05–0.001) on background activity, psychophysiological reactivity, cognitive efficiency and anxiety level. The importance of the effect of anaerobic glycolytic performance on changes in various indicators of the functional status ranged from 4 to 9%. Conclusion. The results obtained prove that anaerobic glycolytic abilities are the leading factor determining not only the inner structure of primary schoolchildren’s functional status and its age-related changes but also the peculiarities of psychophysiological shifts in the functional status under information load.

Aim. The purpose of the article is to develop a method of comprehensive diagnostics for assessing the functional status of weightlifters. Materials and methods. The study involved 14 highly skilled weightlifters at 2 pre-competitive stages of training. The parameters of cardiovascular (heart rate, blood pressure, Gench test), central nervous (differentiation of large and small muscular efforts, statokinetic stability of the body, the speed of sensorimotor reactions), neuromuscular (muscular response threshold) systems were determined. Power capabilities of athletes were investigated. On the 3rd minute of recovery after load blood sampling for lactate analysis was carried out. Results. The results obtained show that at 1 precompetitive stage of training when special exercises are primarily used athletes demonstrate the initial symptoms of fatigue (cardiovascular system and a number of indicators of the central and neuromuscular systems) along with the high level of development of power qualities and high anaerobic capacity. When re-testing athletes during their preparation for the most important competitions provided by a versatile training program, the functional status of the body systems was considered to be high. Conclusion. A comprehensive study allows assessing the fitness of weightlifters from a systemic perspective. The use of the developed method allowed to prove new approaches to training of highly skilled weightlifters.

Aim. The objective of this study is to investigate the effectiveness of Crossfit training in order to minimize performance loss of elite wrestlers during 30-day rest period. Materials and Methods. Total 23 elite male wrestlers who competed at the last national championship participated in this study. The participants were divided into two groups as Crossfit and control group. The Crossfit group performed 5 pull-ups, 10 push-ups and 15 squat exercises consecutively (Crossfit-Cindy) for total 20-min, during the 30-day period, 6 days per week. The Control group did not perform any exercise programs during this period. Before and after the 30-day period, athletes were applied anthropometric measurements as well as VO2max (aerobic capacity), bench press and squat (maximal dynamic strength), leg and handgrip strength (isometric strength), pull-up and push-up (strength endurance) tests. Results. After the 30-day period in the control group, body weight and body fat percentage (BF %) increased significantly, whereas all performance variables decreased significantly. Maximal dynamic strength and aerobic capacity values decreased significantly in the Crossfit group, while body weight, body fat percentage, isometric strength and strength endurance values were maintained. Moreover, the decrease in VO2max and bench press tests was higher in the control group than in the Crossfit group. Conclusion: Consequently, the present study showed that 20-min Crossfit training was highly effective in maintaining the form of elite wrestlers during a 30-day rest period

Aim. In the present paper we aim at highlighting the influence of motion games in improving the components of psychomotricity in the physical education lesson in primary school education (the preparatory school year) and in shaping, among pupils, the belief that the physical education activity is a personal necessity. Methods. During the 2018–2019 school year, within the physical education classes we implemented a program of 20 motion games, for the first semester, and 17, for the second semester, meant to improve the psychomotor components. The research was carried out within the secondary school no. 1 Matca, Galati County, on a group of 50 preparatory school year pupils – the control group (24 subjects – 10 girls and 14 boys) and the experiment group (26 subjects – 13 girls and 13 boys), aged 6–7 years. For the evaluation of psychomotricity, we used the Bruininks-Oseretsky battery of tests, for segmental coordination and upper limb coordination, and the Motorin Test for general coordination. Results. In the final test, due to the implementation of motion games specific to the components of psychomotor activity, we noticed an ease of execution in the experiment group as compared to the control group, which still showed awkwardness and uncertainty in executing certain components of psychomotor activity by repeating the errors made in the initial test. Conclusions. After the creation and application of the training program in the school teaching activity, we reached the conclusion that it led to the acquisition of a high-level psychomotor components, and that it was qualitatively more valuable than the simple use of methods based on simple strength, sprint or endurance running, or dexterity exercises
