Sağlık çalışanlarında fiziksel aktivitenin öfke ifade tarzına etkisi
Authors: AKSOY Yener , SARIYILDIZ Abdurrahman Yunus
Published: June 2022

Bireyler hem sağlıklarını korumak ve geliştirmek hem de zinde bir yaşam için gerekli koşulları sağlamak için fiziksel aktivite yapmaktadırlar. Öfke ise TDK’ya göre; engellenme, incinme veya gözdağı karşısında saldırganlık tepkisi, kızgınlık, hışım, hiddet, gazap olarak tanımlanmaktadır. Burada ortaya çıkan durum bireyden bireye farklılık göstermekle beraber, en basitinden en yoğun öfkeye kadar değişebilmektedir. İşte bu nedenle öfke ifade ediliş tarzına göre değerlendirilmektedir. Bireyden bireye değişen şekilleri vardır. Bunlar; öfke içe vurumu, öfke dışa vurumu ve öfke kontrolü olarak belirtilebilir. Sağlık çalışanları yaptıkları işin gereği olarak stresli bir ortamda çalışmaktadırlar. Aynı zamanda öfke ve şiddet olaylarına da zaman zaman maruz kalmaktadırlar. Kendileri de insan hayatı ile ilgilenmenin bir sonucu olarak öfke ifade tarzlarını kontrol etmektedirler. Bu araştırmada sağlık çalışanlarında fiziksel aktivitenin öfke ifade tarzlarına etkisinin incelenmesi amaçlanmıştır. Araştırma sonuçlarına göre; erkek sağlık çalışanlarının kadın sağlık çalışanlarına göre öfke ifade tarzlarının daha yüksek olduğu tespit edilmiştir. Ayrıca spor yapmayan sağlık çalışanlarının öfke düzeyleri ve ifade tarzlarının daha yüksek olduğu sonucu ortaya çıkmıştır. Bir diğer sonuç ise sigara ve alkol kullanan sağlık çalışanlarının öfke ve ifade tarzları daha yüksek olarak bulunmuştur. Araştırma sonuçlarına göre; sağlık çalışanlarının kendi bireysel özelliklerinden kaynaklanan öfke ifade tarzlarının yoğunluğu onlara verilebilecek eğitimler ile dengelenebilir. Sigara ve alkol kullanımının azaltılması, öfke tarzlarının dengelenmesi açısından önemli olabilecektir. Sağlık çalışanlarının öfke ifade tarzlarını dengeleyebilmek için, fiziksel aktivite yapabilecekleri spor alanları oluşturulabilir.

Authors: LEBLEBİCİ Yeliz , İŞCAN Ömer Faruk
Published: June 2022

Purpose: The study aims to contribute to the management systems and literature by determining whether the mentoring functions of health managers predict the employees' job satisfaction levels.
Material and Method: Mentoring Functions and Job Satisfaction Scales were used as data collection tools. The research universe consisted of health personnel working under the Istanbul Provincial Health Directorate Public Hospitals Presidency-4. The scales were applied to 711 healthcare workers via the web survey application module. SPSS 22.0 and AMOS 24.0 programs belonging to the IBM company were used in the statistical analysis of the article. Descriptive statistics were evaluated as categorical variables as number and percentage, numerical variables as mean and standard deviation. Cronbach Alpha Test and Exploratory Factor Analysis for reliability tests; Pearson product-moment Correlation Coefficient was used to determine the relationships between variables, and the Multiple Linear Regression Analysis test was used to examine the predictor variables. The statistical alpha significance level was accepted as p<0.05.
Results: It was determined that there was a positive and significant relationship between the mentoring functions and job satisfaction perceptions of the healthcare professionals participating in the study (p<0.001). It has been determined that there is a positive and significant relationship between the career development mentoring function and the psychosocial mentoring function of the healthcare professionals. The perceptions of internal and external job satisfaction and the positive mentoring functions of the managers are a predictor of the employees' job satisfaction levels. A positive and significant relationship was found between career development mentoring function and internal job satisfaction. The perception of Career Development Mentoring Function was found to be significantly higher in the employees working in the Training and Research Hospital compared to those working in the State Hospital. The perception of Career and Psychosocial Mentoring Function was found to be significantly higher in doctors than in other occupational groups. External Job Satisfaction According to the hospital employees, it was significantly higher in physicians compared to health licensees and nurses (p<0.001).
Conclusion: It is stated that bringing the mentoring functions of the health managers to the fore will increase the job satisfaction of the employees and that the high job satisfaction in the institutions will increase the self-confidence, morale and performance of the employees; It is thought that it will make institutions more efficient by solving problems such as absenteeism and leaving work due to illness, stress, tension, anxiety, complaints.

Duchenne muscular dystrophy is an inherited disease characterized by progressive muscle degeneration and usually affects boys. The authors reported at the neurology department of the national hospital in Niamey, the case of a family whose boys presented proximal motor deficits in all four limbs, and whose mothers were carriers of cardiomyopathy. The first generation consisted of seven boys and four girls, among which, three boys died of walking disability and breathing disorders, and two of unknown cause. Also, the three girls were carriers of cardiomyopathy and the other died of unknown cause. In the second generation, three boys had died (unknown cause), two were alive and aged 10 and 14 years with walking disability whose balance sheets were abnormal, including CPK (creatinine phosphokinase) and myoglobin. The genetic test showed an out-of-phase duplication of exons 8 to 18 in the latter. Duchenne muscular dystrophy is a rare disease. It is important to think about it when there is a family history of limb-girdle deficit in boys, and to systematically search for cardiac disorders in mothers.

Published: June 2022

Background: Although not a communicable disease, the term “stroke epidemic” is being used widely in the literature. The “epidemic” of stroke might be due to over the time social transmission of unhealthy activities such as unhealthy diet, physical inactivity, and smoking. The aim of this study is to determine the endemic/epidemic pattern of stroke in Maputo Central Hospital in the first semester of 2019. Methods: A cross-sectional study was carried out collecting secondary data (registered cases) from hospitalized patients with stroke. Data from 2014-18 were used to generate the epidemic thresholds. Four threshold epidemic detection methods were used: mean + 2SD; C-SUM; C-SUM + 1.96SD; and the 3rd quartile. Data from January to June 2019 were used to analyze the 2019 trend over the thresholds. Results: An epidemic pattern of stroke was observed during the first semester of 2019 when 3rd quartile and C-SUM threshold epidemic method was used. This epidemic pattern of stroke was not observed when mean+2SD and C-SUM+1.96SD threshold epidemic method was used. A relatively stable pattern of stroke occurrence with high registered cases was observed during the study period. Conclusions: Stroke is an endemic disease for the Maputo Central Hospital, with an epidemic pattern during the first semester of 2019. Adoption of threshold methods for stroke surveillance might well add value for the control of the stroke epidemics.

Introduction. The urgency of the problem is caused by the importance of formation of ability to non-violent interaction in students of socionomic (helping) sphere as the most important professional competence that assumes study of factors and conditions of its formation and development. The aim of the research is to identify the relationship between neuropsychological and personal factors with the choice of students ‒ future medical, psychological, pedagogical psychologists in the process of interaction strategies of coercion or nonviolence.
Materials and Methods. The study involved students from a number of universities in the Russian Federation: Moscow, Cherepovets, Vologda region, Ivanovo, Ivanovo region. In total – 334 people. As a diagnostic tool, the authorʼs questionnaire was used to identify the positions of interaction among students, the Carver ‒ White questionnaire in the adaptation of G. G. Knyazev, the questionnaire for the diagnosis of five personality factors in the adaptation of L. F. Burlachuk and D. K. Korolev, the scale “Moral normativity” questionnaire “Adaptability” Maklakov – Chermyanin. Mathematical processing was carried out with the help of correlation analysis; Spearman ʼs rank correlation coefficient was also used.
Results. It was established that the choice of coercion strategy by students in the process of interaction is associated with a high level of behavioral activation, low levels of benevolence, conscientiousness and moral normativity. The choice of manipulation strategy, in addition to this, is correlated with high neuroticism. Nonviolence is positively associated with benevolence, conscientiousness, and moral normativity, and negatively to neuroticism. Noninterference correlates negatively with the Behavioral Inhibition System and positively with the Behavioral Inhibition System, as well as with neuroticism, introversion and closeness to experience and low conscientiousness.
Discussion and Conclusion. The obtained results make a certain contribution to understanding of the problem of the relationship between students’ choice in the process of interaction of strategies of coercion or nonviolence with neuropsychological and personal factors, which makes it possible to develop special programs aimed simultaneously at teaching methods of nonviolent interaction, and at the development of certain personal qualities, taking into account individual severity. systems of activation and inhibition of behavior.

Published: June 2022

Introduction. The article examines the problem of the formation of readiness and ability for self-development among gifted rural schoolchildren as resource qualities of a personality that characterize the potential of its self-realization. The relevance of the problem is determined by the systematic nature of the support of gifted schoolchildren, which assumes consideration of the individual qualities of gifted subjects, the specifics of which, in this case, is determined by living in rural areas. One of the key tasks of systematic psychological and pedagogical support of gifted children and students in rural schools is to help them to know and understand themselves, to reveal their interests, abilities, to teach them to use the properties of their personality as internal resources for effective interaction in society, successful learning, self-realization and high achievements.
Materials and Methods. The sample of subjects included 420 schoolchildren from eight rural schools of the Altai Territory. Among them, 49 people identified as gifted. The basic model for identifying the giftedness of schoolchildren was the three-factor model of J. Renzulli. To study the readiness for self-development, the ability to self-development and self-education, test methods and questionnaires were used.
Results. It is empirically revealed that the majority of gifted rural schoolchildren has low readiness for self-development and has differences by gender: it is higher in boys than in girls. Among the schoolchildren with undiagnosed giftedness there are more of those who are ready for self-improvement, but not ready for self-knowledge. Intellectual characteristics are more pronounced in gifted boys than in gifted girls; creative characteristics are more pronounced in gifted girls than in gifted boys.
Discussion and Conclusion. The results of the study open up new opportunities for the development of practical methods of psychological and pedagogical activity for the correction and prevention of the identified difficulties in the conditions of rural educational and cultural space. The materials of the article will be useful to the subjects of the educational space, engaged in system interaction in the effective development of the giftedness of children and youth.
The Results of the Combine Design Adaptation to Work with a Stripper Header
Authors: Ozherelev Viktor N. , Nikitin Viktor V.
Published: June 2022

Introduction. A decrease of damaging loose grains by threshing tools when combing standing plants is an urgent scientific problem. The aim of the research is to develop a technical solution and experimentally confirm the possibility of loose grains pre-separation from the stripped grain heap before it enters the threshing chamber of the combine harvester.
Materials and Methods. The most promising technical solution to minimize the damaging of loose grain is an inclined chamber containing an oblong-hole lattice bottom, under which inclined augers are mounted. The experimental studies had two stages. In the first series of experiments, in laboratory conditions there were determined the optimal sizes of the lattice bottom holes to ensure the maximum passage of loose grains. In the second series of experiments, the degrees of separating and damaging loose grains were evaluated in real field conditions.
Results. According to the results of laboratory studies, it was found that the maximum passage of loose grains through the holes of the lattice bottom is 68.7% with the width of holes 8 mm and their length 160 mm. According to the results of field experiments, it was found that the average passage of loose grains through the holes of the lattice bottom is 90%. At the same time, damaging grains in the inclined chamber did not exceed 0.5%, and in the hopper 1.75%. Damaging grains in the bunker was in the range of 5.25% when the combine operated without pre-separation of the combed grain heap on the lattice bottom of the inclined chamber.
Discussion and Conclusion. Pre-separation of loose grains from the combed heap makes it possible to reduce damaging grains at least three times, and also reduces the power consumed by the drive of the threshing machine by 11–12%.
Dynamics of Fractional Composition of Grain-and-Straw Mass Being Threshed in the Threshing Mechanism of a Combine Harvester
Authors: Zhalnin Eduard V. , Chaplygin Mikhail E.
Published: June 2022

Introduction. The article presents the results of theoretical and experimental studies of threshing and separation processes in the threshing mechanism of the combine harvester with a digital assessment of the fractional composition of the grain-and-straw material being threshed. The obtained data will allow detecting dynamics of fractional composition of grain-and-straw mass being threshed in the threshing gap of the threshing mechanism depending on its supply.
Materials and Methods. The research was carried out on a special stand in the form of a separate unit of the combine threshing mechanism. Grain-and-straw samplers were installed under each threshing section. The mass feed was changed from 1.0 to 6.0 kg/s at a straw ratio of 1:1. The obtained data were approximated using a standard procedure.
Results. There was determined the amount of grain and straw passed through the threshing section screen and the rest of grain and straw entering the straw separator depending on their initial amount. For each fraction, there were determined the ratio of straw mass to grain mass, the density and thickness of the grain-and-straw heap layer on the shaking board ahead of the grates and at the beginning of the straw separator keys. The dynamics of grain-and-straw separation was identified by scanning the length of the grains with the determination of the density and compression degree of the grain-and-straw mixture layer in the threshing gap.
Discussion and Conclusion. It was found that in the heap of grain-and-straw passed through a threshing section, the ratio of straw mass to grain mass decreases from 0.46 to 0.27 and density increases from 60.1 to 84.0 kg/m3. In the heap of grain-and-straw that fell on the straw separator, the ratio of the straw mass to the grain mass decreases from 11.2 to 2.0, the density increases within a small range from 21.7 to 26.4 kg/m3. Thickness of the heap layer on the shaking board in front of the cleaning sieves varies in the range 0.25‒10.20 cm, and on the straw walker ‒ 2.2‒19.8 cm when changing the supply of the total mass for threshing from 1 to 6 kg/s.
“Gradient” Experiment in Horticulture Lighting
Authors: Rakutko Elena N. , Rakutko Sergey A.
Published: June 2022

Introduction. A characteristic feature of most experimental research works on horticulture lighting is the need to vary the main parameters of the light regime while maintaining other environmental factors at the same level throughout the experiment. The approach to creating the requisite variety of variations of light regime parameters in one cycle of plant cultivation, considered in this work, may be acceptable for reducing the time of experiments or for exploratory works. The aim of the work is to show the possibility of using the illuminance gradient as a source of variation in its value in experimental works on horticulture lighting.
Materials and Methods. We used an LED lamp with a cosine light spatial distribution, placed above the work surface, on which containers with sweet pepper plants were placed. The optical density of the leaves in various spectral ranges was used as a biometric parameter characterizing the response of a plant to the level of illumination.
Results. A significant gradient of illumination was observed on the working surface. With the same range of illumination, the number of containers with plants for a given zone is different and is sufficient to test statistical hypotheses. The values of the average illumination by zones provided the range of illumination change by 2.5 times. The standard deviations of illumination by zones were 97–163 lux and were practically no correlated with the values of the average illumination.
Discussion and Conclusion. The developed mathematical model of a gradient experiment in horticulture lighting makes it possible to determine the possible number of replicates during the experiment, the average illumination value, the standard deviation, the coefficients of variation and uniformity in each zone of plant placement, based on the lighting and layout parameters of the lighting installation. It has been experimentally found that the use of a luminaire with a cosine light distribution provides an illumination gradient on a horizontal surface, the average values of which in individual zones form a linear illumination scale. Coefficients of illumination variation in individual lighting zones with the parameters set in the example were 3.0–11.5%. The coefficients of variation of the optical density of the leaves of pepper plants grown under the conditions of the gradient experiment on illumination were 6.0–11.6%. The differences in the mean values of the optical density of plant leaves in different zones of gradient illumination are statistically significant. This allows us to recommend the use of the proposed method for searching experiments on horticulture lighting.
The Matrixial Screen Encounter: theorising the inter-subjective gaze in the documentary practice of Kim Longinotto
Authors: Mairs Dyer Jolene Alexandria
Published: June 2022

This article applies Ettinger’s (2001) notion of the matrixial to the documentary practice of Kim Longinotto.  It considers this in relation to what I term the matrixial screen encounter, a model that expands the individualistic framing of the unitary auteur and acts as a counter to the notion of the impartial observer within the context of observational documentary.  It applies this model to a scene from Longinotto and Mir-Hosseini’s 1998 documentary, Divorce Iranian Style and demonstrates how the matrixial screen encounter offers a way of mapping and considering the inter-connected, inter-subjective gazes, or layers of power within the scene, which are predominantly female and feminist.  It concludes that the matrixial screen encounter provides a way of re-thinking the unitary, authoritative gaze of the auteur and the supposed impartiality of the camera-as-observer – reinforced by the term observational documentary - where the screen itself becomes a ‘locus of mediation’ at which various matrixes, gazes or layers of power, meet.

Exploring PM2.5 variations from a low-cost sensor network in Greater Kampala, during COVID-19 imposed lockdown restrictions: Lessons for policy
Authors: Green Paul , Okure Deo , Adong Priscilla , Sserunjogi Richard , Bainomugisha Engineer
Published: June 2022

Air pollution is considered a major public health risk globally, and the global South including sub-Saharan Africa face particular health risks, but there is limited data to quantify the level of pollution for different air quality contexts. The COVID-19 lockdown measures led to reduced human activities, and provided a unique opportunity to explore the impacts of reduced activities on urban air quality. This paper utilises calibrated data from a low-cost sensor network to explore insights from the diverse ambient air quality profile for four urban locations in Greater Kampala, Uganda before and during lockdown from March 31 to May 5 2020, highlighting the uniqueness of air pollution profiles in a sub-Saharan African setting. All locations saw year to year improvements in 24-hour mean PM2.5 between 9 μg/m3 and 25 μg/m3 and correlated well with reduction in traffic (up to approx. 80%) and commercial activities.
The greatest improvement was observed in locations close to major transport routes in densely populated residential areas between 8:00 pm and 5:00 am. This suggests that the reduction in localised pollution sources such as nocturnal polluting activities including traffic and outdoor street cooking characteristic of fast-growing cities in developing countries, coupled with meteorological effects led to amplified reductions that continued well into the night, although meteorological effects are more generalised. Blanket policy initiatives targeting peak pollution hours could be adopted across all locations, while transport sector regulation could be very effective for pollution management. Likewise, because of the clustered and diffuse nature of pollution, community driven initiatives could be feasible for long-term mitigation.
Air pollution abatement by selective nanoparticle deposition on filtration systems
Authors: Nag Ishika
Published: June 2022

Air pollution kills an estimated seven million people worldwide every year. The data from the World Health Organization (WHO) shows that almost all the global population (99%) breathe air that exceeds WHO guideline limits. The growing population and urbanization such as in Africa, which has the fastest growing population, may lead to substantial worsening of the air quality. Urbanization is also a powerful driver of the epidemiologic transition from traditional threats like infectious diseases and malnutrition to chronic, non-communicable diseases. Particulate matter less than 2.5 microns in size, PM2.5, is the leading contributor to air pollution which results in such diseases like chronic obstructive pulmonary disease (COPD), bronchitis, and lung cancer. Recent studies have shown a strong correlation between ambient air pollution and COVID-19 cases, which has affected the lives of billions of people around the world. Abatement technologies such as ionic and other high efficiency filtration systems are quite expensive and hence unaffordable to communities with limited resources. The goal of this study was to develop an air pollution filtration method utilizing selective nanoparticle deposition in optimized concentrations, to maximize the entrapment of PM2.5 particles. The experimental set-up consisted of a wind tunnel with incense sticks as the PM2.5 source, measured by laser particle detectors upstream and downstream of the filters. Different nanoparticle coated filters were tested using the ‘Design of Experiments’ methodology and it was concluded that an optimized mixture of zinc oxide, titanium dioxide & graphene improved filtration efficiency of a baseline filter by 206% and was 70% cheaper than high efficiency filters. The versatility and cost-effectiveness of this design makes it applicable for personal masks & filters, air-conditioning and car-cabin filters, and fire-fighting equipment. The significant correlation between air pollution and fatalities from viral infections like COVID-19, makes such abatement technologies with innovative filtration systems critical to save human lives.
use of dirty fuels by low-income households on the South African Highveld
Authors: Pauw Christiaan , Murray H. Montagu , Howard Marcus A.
Published: June 2022

Meaningful proportions of households on the South African Highveld regularly use energy carriers that result in the emission of significant quantities of particulate and gaseous pollutants. Dirty fuels are mostly used by lower-income households, with the exception of recreational wood use that is also prevalent in higher-income households. The dirty fuel use patterns and trends observed on the Highveld are the result of the unique combination of the utility, accessibility, affordability, availability, and desirability of the energy carriers and equipment, climatological factors, markets and infrastructure, as well as the inertia of historic energy use patterns. There are no systematic reviews and prognosis of the use of dirty fuels by low-income households on the South African Highveld that consider critical recent events such as the Covid pandemic and emerging dynamics such as the just transition movement. In this article we will use a literature review as well as our own research to describe dirty fuel use by low-income households on the Highveld, paying specific attention to changes over time. We will attempt to describe what is being used, who the users are, and for which utilities fuels are being used. From these descriptions, specific patterns emerge that shed light on possible avenues and prospects for ending dirty fuel use on the Highveld.
A street-level assessment of greenhouse gas emissions associated with traffic congestion in the city of Nairobi, Kenya
Authors: Sitati Cynthia N. , Oludhe Christopher , Oyake Leah , Mbandi Aderiana M.
Published: June 2022

Traffic congestion significantly contributes to climate change due to the emissions of Greenhouse Gases (GHGs) such as Carbon Dioxide (CO2), Nitrous Oxide (N2O), and Ozone (O3). Rapid urbanization and poor planning coupled with increased motorization and fragmented public transport system in cities such as Nairobi have led to increased vehicular emissions especially during heavy traffic along the various roads and within the Central Business District (CBD). To reduce GHG emissions in the urban transport sector, institutional coordination and relevant policy tools must be considered. This study aimed at estimating CO2 emissions from different vehicles during traffic congestion, using Uhuru Highway as a case study. The relationship between traffic congestion and CO2 emissions was analyzed using qualitative and quantitative methods, through a bottom-up approach. Questionnaires were administered to get individual vehicle characteristics and opinions on the best actions for the reduction of CO2 emissions along Uhuru Highway in Nairobi. The Average Annual Daily Traffic (AADT) for different vehicles from 2014 to 2019 was used to estimate the CO2 emissions. Results showed that private cars predominate over other vehicle types, contributing to 73% of the total CO2 emissions in Nairobi (CBD). Private cars are the highest contributor of CO2 emissions with a total of 25.3 million Carbo dioxide equivalent (gCO2e), between 2014 and 2019. In comparison, Public Service Vehicles, commonly referred to as Matatus emitted 6.89 million gCO2e, Light Commercial Vehicles (1.82 million gCO2e), Heavy Goods Vehicles (251,683 gCO2e), and motorcycles (181,054 gCO2e). To minimize CO2 emissions, the study recommended the enforcement of strong mobility policies to control the high motorization rate. One of these policies is the prioritization of the development of the mass public transport systems to achieve the potential health, economic and environmental gains within the CBD.
Effect of Physical Development Self-Assessment Indicators on Value Orientation Structure Formation in Senior School Age Students
Authors: Bakiko Ihor , Krutsevich Tetiana , Trachuk Sergii
Published: June 2022

Background. Physical education as a subject in general secondary education institutions aims not only to solve health and educational problems but also to form a value attitude to health, healthy lifestyle, fostering the interest in and the need for physical activity.

Research purpose. The study aims to investigate the relationship between senior school age students’ value orientations and physical development self-assessment indicators to determine incentives to increase motivation for self-improvement by means of physical education.

Materials and methods. The research methods used to solve the tasks set in the paper were as follows: analysis and generalization of data of scientific and methodological literature; content analysis; comparison and juxtaposition method; Ye. Bochenkova’s test-questionnaire Self-description of physical development, M. Rokych’s technique for defining value orientations; methods of mathematical statistics. 

Results. Based on examining correlations between the 11th grade students’ terminal values and physical development self-assessment, a tendency was found to shift the priority of youth values towards life values, values of professional realization, and values of interpersonal relationships. Based on the results of the study, we found that the formation of value orientations in boys and girls in high school can affect self-esteem, which in turn is a stimulus for self-improvement and, through an effective component of physical activity, increases the importance of “health” for senior school age boys. On the other hand, girls have no such pattern, and the value of “health” is declarative for them.

Conclusions. It has been determined that the formation of value orientations through an effective component of physical activity can affect the self-esteem of boys and girls, which in turn is an indicator of self-awareness and expresses the individual’s attitude to himself and is the basis for regulating their own behavior.

The study purpose was to compare high impact aerobic dance exercise versus Zumba to increase Maximum Oxygen Volume (VO2max) in adolescent women.

Materials and methods. This research is quasi-experimental with a two-group pretest-posttest design research design. A total of 30 adolescent women from the Student Activity Unit (UKM) aerobic gymnastics at Universitas Nusantara PGRI Kediri, aged 18-24 years, body mass index (BMI) 18.5-24.9 kg/m2, normal blood pressure participated in the study. Respondents were randomly divided into two groups, namely ZADE (n = 15, Zumba aerobic dance exercise) and HADE (n = 15, High impact aerobic dance exercise). HADE and ZADE were conducted for 30 minutes/session, with an intensity of ≥ 85% HRmax, as often as 3 times/week, and both types of training were performed for 8 weeks. Measurements of VO2max, oxygen saturation (SpO2), and heart rate at rest (HRrest) were pre-test and 1×24 hours post-test after 8 weeks of training intervention. Statistical analysis used Paired Sample T-Test with a significance level of 5%.

Results. Paired Sample T-Test results showed significant differences in average VO2max, SpO2, HRrest between pretest vs. posttest in both groups (p ≤ 0.001).

Conclusions. Based on the study results, we have concluded that both HADE and ZADE increase VO2max, SpO2, and decrease HRrest. But HADE is more effective in increasing VO2max, SpO2, and lowering HRrest than ZADE in adolescent women.

Background. Telerehabilitation used as an exercise method has become increasingly common in recent years. Various methods have been used to increase hamstring flexibility, but more research is required on the optimal program.
The study purpose was to investigate the effect of hamstring stretching exercises given as telerehabilitation and home exercise program on hamstring flexibility.
Materials and methods. Sixty-eight healthy adults were randomly assigned to two groups, namely telerehabilitation and home exercise. Exercises were performed for 8 weeks (4 sessions/week) in both groups. Active and passive range of motion (ROM), sit and reach test (SRT), and International Physical Activity Questionnaire Short Form (IPAQ-SF) were conducted in the pre- and post-intervention and after a 6-month period. 
Results. At the end of 8 weeks, a significant improvement was observed in the SRT scores in both the telerehabilitation group (p = 0.001) and the home exercise group (p = 0.001). In addition, significant improvements were observed in the passive ROM measurements of both the telerehabilitation group (p = 0.005) and the home exercise group (p = 0.001). At the end of 8 weeks, the telerehabilitation group was found to be significantly superior to the home exercise group in the SRT results (p = 0.034). As for the long-term results, significant improvement was maintained in both SRT (p = 0.001) and passive ROM (p = 0.014) in the telerehabilitation group.
Conclusions. Eight-week telerehabilitation and home exercise program was observed to have positive effects on passive and active ROM. The telerehabilitation method may prove to be more effective than the home exercise method in the long term.

Research purpose. The purpose of this study is to verify if there are significant differences between different anthropometric and jumping ability variables by testing two groups of elite and amateur volleyball players (under 16) after having submitted the two groups to the same training protocol performed 4 times a week for 4 months.

Materials and methods. The study was carried out on 24 volleyball players divided into two groups. The following anthropometric and jumping ability parameters were assessed in all subjects: height, weight, body mass index, height with a stretched arm and height with two extended arms. The jumping ability measurement was carried out with the Vertec jump test.

Results. The results of the anthropometric parameters showed significant differences between the two groups on all the variables considered:  in height (p = 0.00), in weight (p = 0.00), in Vertec attack with a stretched arm, AH1 (p = 0.00) and in Vertec wall with two outstretched arms, AH2 (p = 0.01). The results of the jumping ability parameters showed significant differences between the two groups (elite and amateur):  in Vertec Wall, VW (p = 0.00) and Vertec Attack with run-up, VA (p = 0.00); and a high correlation was shown for both the groups.

Conclusions. Above all, in high-level youth volleyball, the anthropometric and jumping ability profile is directly linked to the evaluation; training and continuous monitoring of physical qualities and jumping ability become an important aspect for the control of performance and the possibility of selecting talented players.

The study purpose is to establish differences in the joint activities of soccer teams of different age.

Materials and methods. Psychological methods for indicators of joint activity of sports teams were used. Statistical analysis was performed using non-parametric analysis of variance (Kruskal-Wallis H-test). The study involved 105 soccer players, including 37 boys aged 15–18, 45 juniors aged 19–21 and 23 adult athletes aged 22 and over.

Results. In the young soccer players, group interaction, intellectual communication, psychological compatibility, as well as indicators of real and reflective group subjectivity are higher than in the adult and junior teams. The levels of group organization, diligence and success in performing sports tasks are dominant in the adult teams. At the same time, the integrative characteristic of joint sports activities is group efficiency, which is presumably the most pronounced in adults, thus characterizing the processes within the mental organization of joint activities of soccer players. It is the result of their cooperation, a transformed form of external teamwork.

Conclusions. The organization of joint mental activity differs in different age groups. This affects the formation and development of intra-group position of the athletes, influencing their optimal involvement in the team in the performance of designed or creative functions.
