In the sport of futsal, enhancing shooting speed is crucial for performance, yet there is a lack of targeted training methods that effectively improve this skill among student players. This study aimed to analyze the effect of plyometric single-leg hurdle hops combined with backward run training on shooting speed in student futsal players. A quasi-experimental design with a one-group pretest–posttest approach was employed. The population consisted of 25 student futsal players, and the sample included 15 players with a mean age of 14.67 ± 0.49 years, height of 160.73 ± 4.46 cm, weight of 50.20 ± 5.93 kg, and BMI of 19.42 ± 2.02, selected using purposive sampling. Shooting speed was measured using a camera, and the recordings were analyzed with the Kinovea application. The results showed a significant increase (p<0.05) in shooting speed following the training program. The mean shooting speed improved from 28.3±2.02 m/s in the pretest to 30.4±2.20 m/s in the posttest, with a mean difference of 2.04±1.98 m/s and a 2-tailed significance value of 0.001 (< 0.05). In conclusion, plyometric single-leg hurdle hops combined with backward run training significantly improved shooting speed in student futsal players.

The aim of the study is to investigate the impact of surgical and non-surgical rehabilitation programs on anterior and posterior cruciate ligament (ACL) injuries in team sports athletes, such as football, basketball, and handball. The methodology used was the descriptive-analytical approach using objective measures. The study included a sample of 60 players aged between 18 and 30 years who had suffered a cruciate ligament injury. The sample was divided into two groups: one group underwent surgical rehabilitation after ACL reconstruction surgery, and another group underwent non-surgical rehabilitation through specialized therapeutic exercises. The researchers concluded that the study showed that surgical rehabilitation for ACL injuries was more effective in improving range of motion, reducing pain, and increasing muscle strength compared to non-surgical treatment. Additionally, the researchers recommended the necessity of designing specialized rehabilitation programs that consider the nature of the injury and the needs of each player to ensure the restoration of movement and safe return to competition

ABSTRACT “Workation” is a new type of remote work in response to the increasing digitalization and flexibilization of work. By facilitating a combination of the domains of work, recreation and private life with an optional touristic-oriented pursuit, workation spaces promote flexible work practices and have significant impact on the working lives of knowledge workers, companies and several industries worldwide. While the original task of the real estate industry is to provide jobs in the form of offices, new players are suddenly entering the market, such as the hotel industry. This interesting mixture opens up exciting research approaches. There exists a rather extensive knowledge gap in literature understanding these work–leisure activities. Particularly striking is the lack of a clear classification of workation and little empirical evidence on workation exists. Therefore, this paper aims to provide a coherent descriptive basis, definition and classification of workation based on first empirical evidence by outlining a case study. The conceptual analysis finds that workation can be categorized into three types – traditional workation, coworkation and workation retreat – each with different characteristics. Finally, affected industries are studied and effects from workation on economies are shown. By providing a first taxonomy of workation, this paper might serve as a basis for further research.

One of the reoccurring questions that arises during the countermovement vertical jump (CVJ) assessment is whether the learning effect has an impact on the accuracy of the results obtained. Thus, the purpose of the present investigation was to examine the impact of the short-term learning effect on the assessment of lower-body neuromuscular performance characteristics when performed on a portable one-dimensional force plate system. Sixteen recreationally active college-age males volunteered to participate in the present study. Each participant completed four sets of three non-consecutive CVJs with no arm swing throughout a single day. Besides strong verbal encouragement, participants were constantly instructed to focus on pushing the ground as explosively as possible. Fourteen force-time metrics were selected for CVJ performance analysis purposes: eccentric and concentric peak and mean force and power, eccentric and concentric duration, contraction time, jump height, reactive strength index-modified, and countermovement depth. Repeated measures multivariate analysis of variance was used to examine statistically significant differences across four testing time points (p &lt; 0.05). The results indicate an absence of any meaningful differences across four testing time points in force-time metrics of interest during both eccentric and concentric phases of the CVJ. Moreover, no differences were observed in CVJ outcome metrics such as countermovement depth, suggesting that the movement strategy tends to remain consistent. Overall, these findings reveal that CVJ test repeatability is not affected by the short-term learning effect and that data are stable at least within the scope of this study and within this population.

Depression is a common mental health disorder that affects the majority of the population. The exact cause of depression is not fully understood, but various factors such as genetics, environmental stressors, and psychological factors are believed to play a role. Due to the complexity of the etiopathogenesis of depression, the selection of appropriate therapeutic management is sometimes complicated. Treatment for depression typically involves a combination of medication and psychotherapy. Antidepressant medication can help alleviate symptoms by regulating neurotransmitters in the brain, while psychotherapy can help individuals understand and change negative thoughts and behaviors. Physical activity, such as sport, has been shown to have a positive impact on mental health and can help alleviate symptoms of depression. Exercise releases endorphins, reducing stress and improving mood. Health education can also play a role in preventing and managing depression by raising awareness, reducing stigma, and teaching individuals coping skills to maintain good mental health.

The aim of the study was to examine the effect of walking football applied to elderly male sedentary individuals on life satisfaction and heart rate variability. 22 male volunteers whose physical activity level was determined by International Physical Activity Questionnaire (IPAQ) were included to this study. Volunteers were divided into 11 exercise groups and 11 control groups by random sampling. While the control group had no activity participation, the exercise group performed a 20-minute warm-up, they played 60 minutes of walking football, and they performed a 10-minute cool down. This was done 2 days a week across an 8-week period. In the study, the Life Satisfaction Scale (LSS) was used in the exercise and control groups, Heart Rate (HR), Heart Rate Variability (HRV), heart-mind coherence, maximum heart-mind coherence measurements were applied with the Heartmath-Inner Balance device. “Paired t test” was used for analyzing pretest-posttest differences in variables while "Independent t test" was used for analyzing differences between the groups. Findings show that there was a significant difference between the exercise group’s HRV, heart-mind coherence, maximum heart-mind coherence, and pre-post test measurements of the LSS results (p&lt;0.05), although there was no significant difference in the HR variable (p&gt;0.05). No significant difference was found between the pre-test and post-tests mean comparison of all variables of the control group (p&gt;0.05). According to the results, it can be concluded that walking football has a positive effect on life satisfaction, HRV, heart-mind coherence, and maximum heart-mind coherence in older adults.

Background. The COVID-19 pandemic has forced entering numerous changes and restrictions on daily psychosocial functioning. The purpose of our research was to explore the views of adolescents aged 14-20 years attending secondary schools on the role of vaccination and the restrictions put in place during the COVID-19 pandemic. Material and methods. The study was conducted with 504 secondary school students in a small town in Poland. Students were aged between 14 and 20 years (M = 16.6, SD = 1.3). The groups were homogeneous in terms of age and gender. 250 males (M = 16.5; SD = 1.3) and 254 females (M = 16.7; SD = 1.4) completed the sheets.   The survey took place between January 7 and 11, 2022. The study used the author's “Pandemic and My Life” survey method. It contained 7 closed-ended questions covering adolescents' attitudes towards COVID-19. Results. More than half of the students have been vaccinated against COVID-19, and they are convinced of the effectiveness of the vaccines. Females were more likely to reveal anxiety before infection. Despite the presence of the COVID-19 virus in many families’ homes, concerns about infection were rather small. A great number of the respondents assessed restrictions as “more burdensome than beneficial”. Males were more prone to accepting distant education. There was a relationship between students' fear of the COVID-19 infection and the anxiety observed by pupils in their families. Conclusions. The majority of the adolescents surveyed have been vaccinated against COVID-19 and have positive opinions about the effectiveness of the vaccines. There is a strong polarisation of views on some issues. The results obtained can be helpful in building preventive programmes and shaping pupils' health-promoting attitudes.

As a result of the spread of the COVID-19 pandemic, tourism, as one of the branches of many national economies, has suffered heavy losses both nationally and regionally. The pandemic as a global phenomenon is bound to change tourism, at least for some time to come. Therefore, questions arise about the nature of these changes and how deep they will be. The aim of the article is to show that for Podkarpackie Province in Poland, the COVID-19 pandemic, apart from the obvious negative consequences for the tourism industry, has also brought new development opportunities. The analyses presented here are based on a survey conducted among 948 adult respondents in 10 different locations within three districts between 15 and 30 August 2020. The analysis showed that during the pandemic, nature-related travel and active tourism, as well as trips aimed at health recovery were in high demand. Ensuring health and safety on holidays became a priority. Therefore, a concentration of tourism was observed in selected domestic destinations, usually in areas not associated with tourism (e.g. rural areas). In the future, this may create opportunities for a revival of local tourism. In contrast, the tourism industry suffered its greatest losses in cities; business and event tourism lost out, and there was a significant drop in revenue from both domestic and foreign tourists. These results indicate the negative effects of the pandemic, but also show new development opportunities. No one knows how long COVID-19 will continue, so the conclusions may be useful both for entrepreneurs preparing their tourist offers in the coming years, and institutions responsible for regional tourism policy.

Os jogos eletrônicos se desenvolveram durante os anos, sendo conhecidos por muito tempo como um tipo de atividade recreacional e de lazer. O crescimento da internet possibilitou o surgimento de um novo cenário, em que alguns jogadores puderam se profissionalizar, originando o e-Sport. Objetiva-se apresentar um histórico sobre o desenvolvimento dos jogos eletrônicos e sua passagem de uma prática de lazer para uma atividade esportiva profissional. Conclui-se que a disseminação dos e-Sports se deve às características modernas, dinâmicas e distintivas que os esportes eletrônicos têm adquirido, à vasta procura e, consequentemente, oferta da prática, sendo visível a presença dos processos de mercantilização, espetacularização, amadorismo, institucionalização e profissionalização que os e-Sports passaram e passam, com cada processo não ocorrendo de forma linear um com o outro, mas sim interconectados.

<p><strong>The aim of the work</strong> is to determine the factors of the course of GERD in children and adolescents which are important for predicting the development of magnesium deficiency.</p><p><strong>Materials and methods of research. </strong>For the study 77 people aged 9 to 14 years, who have gastroesophageal reflux disease with endoscopically positive diagnostic result, were examined. All children who were involved in the study underwent laboratory tests of serum magnesium, intracellular (erythrocyte) magnesium, and calcium levels. The ratio of calcium and intracellular magnesium was also considered as an indicator of latent magnesium deficiency. Magnesium level in patients with GERD were compared with control group, which consisted of 20 children without GERD. The odds ratio and confidence intervals for a large number of anamnestic, clinical and instrumental factors of GERD were calculated to determine significant prognostic factors for the development of magnesium deficiency, after which the indicators of the relative risk and the minimum and maximum predictive coefficients for these factors were determined. Based on the indicators of the minimum and maximum prognostic coefficient, a range of the probability of magnesium deficiency in patients with GERD was formed.</p><p><strong>Results.</strong> Based on the determination of the level of serum, erythrocyte magnesium, and the ratio of Ca/Mg_erythrocyte in children of the control group, who were practically healthy, the standard deviation (δ) was calculated, and the corridors of laboratory parameters corresponding to the normal level of magnesium, indicators of latent deficiency (from δ to 2δ) and indicators of deficiency of magnesium (more than 2δ) were determined. In the group with GERD normal magnesium levels were discovered in 41.6% of children. A total of 19.5% of patients had latent magnesium deficiency and 39% of children had magnesium deficiency. For the analysis were selected: hyperacidity (pH 0.86-1.59), which had an odds ratio of 3.47; the reflux esophagitis 2-3 stages with an odds ratio of 68.64; an increase in LF and HF values day and night, an increase in the daytime LF/HF ratio, an increase in the stress index, an increase in PAPR and average circadian index values. Based on the indicators of the minimum and maximum prognostic coefficient, a range of the probability of magnesium deficiency in patients with GERD was formed. With the sum of the predictive coefficients of each significant factor from 13.3 to 31.0, the probability of magnesium deficiency is low; the range from 31.1 to 48.8 corresponds to the average probability, and the range of 48.9 to 66.5 indicates a significant possibility of a magnesium deficiency in a patient with GERD.</p><p><strong>Conclusion</strong>. It was determined that the factors of hyperacidity and the reflux esophagitis, some indicators of heart rate variability (LF and HF day and night, an increase in the daytime LF/HF ratio, an increase in the stress index, an increase in PAPR and average indicators of the circadian index) can be used to predict the development of magnesium deficiency in children with GERD. The practical application of the predictive coefficients of the given factors will make it possible to timely correct magnesium deficiency and will positively affect the quality of GERD treatment in children and adolescents.</p>

Background. A lot of studies have shown the Differential Training (DT) is more effective than the traditional training based on repetition at constant conditions. The aim of this study was to find the changes in dynamical concatenation between ECG parameters during the DT task. Methods. Participants (13 healthy adult males) performed two balance tests standing on LIBRA balance board. Continuous ECG registration during both balance tests and during the rest was 3 minutes. The changeable parametric interactions and its dynamics during exercise tasks while monitoring ECG parameters and its data sequences analysis based on mathematical method based on matrix theory were applied, the concatenation between ECG parameters were analysed. Results. Results obtained during the study showed that there were no drastic differences between ECG parameters while performing both balance tests. The concatenation between analysed ECG parameters increased or there was no significant change. The decrease of concatenation was observed during the second task while the participants performed the squats standing on the balance board. This type of change in concatenation was found during the analysis of all ECG parameters, i.e. between duration of RR intervals and QRS, between JT and RR intervals and between QRS and JT intervals. Conclusion.  DT  tasks  trigger  the  decrease  of  concatenation  between  cardiovascular  parameters  that  allows discussing about the hypothesis that decrease of concatenation between systemic regulatory commands and cardiac metabolic changes could be one of possible chain activating and enhancing the efficiency of long-term adaptation at conditions of DT. Keywords:  cardiovascular system, concatenation, Differential Training.

Research background and hypothesis. The objective methods of measuring physical activity (PA) are used more and more widely in various types of research. However, in Lithuania there is a lack of such studies with adolescents. Thus, we conducted a pilot study to objectively measure boys’ PA and to develop a more accurate PA assessment methodology in Lithuania. The purpose of this study was to analyse the objectively measured adolescent boys’ weekly physical activity and its relation to their body composition and physical fitness. Research  methods.  The  participants  of  this  study  were  104  healthy  adolescent  boys.  Physical  activity  of schoolboys was measured using actigraphs (Tri-axis ActiTrainer Activity Monitors). The level of the intensity of physical activity was determined by calculating energy consumption in MET’s. Low PA (LPA) equals up to 3 MET’s, moderate PA (MPA) – 3–6 MET’s, and vigorous PA (VPA) – 8 or more METs. Based on the frequency of VPA and MPA per week, the participants of this study were divided into physical activity groups. For health-related physical fitness  assessment  the  following  tests  were  used:  body  composition  (using TANITA  Body Analyser, TBF-300); flexibility (sit and reach test, Eurofitas, 2002), power (vertical jump was measured using a jump parameter gauge (SBM-1), muscular strength and endurance (modified push-up test (Suni et al., 1994)). Research results. All of the schoolboys demonstrated LPA on each day of the assessment. MPA on each day was experienced by 59.6% of the boys. No participants achieved VPA . The most frequent MPA and VPA were observed 5–7 and 1–3 days per week, respectively. Results of body composition indicated that boys experiencing VPA had lower body fat mass compared to those who experienced only MPA and LPA (p < 0.05). Analysis of physical fitness results indicated that boys who experienced VPA were better muscular in strength and endurance test (p < 0.05), but results of high jump and sit and reach test were not significantly different. Discussion and conclusion. Boys who experienced VPA at least for 3 days/week demonstrated better muscular strength and endurance results and had lower body fat content (%) (p < 0.05). For boys who did not experience MPA at least for 6 days/week, the total amount of weekly physical activity decreased and they could not produce better results in strength and endurance test (p < 0.05). Better results of boys’ muscular strength and endurance were  significantly related to their body lower BMI (r = 0.279; p < 0.05) and fat mass (r = 0.387; p < 0.01). Objectively Measured Weekly Physical  Activity among Adolescent Boys and its  Relation to Health-Related Physical Fitness Keywords: physical activity, MET’s, actigraphs.

The aim of this study was to examine the effect of play-based early intervention on psychomotor development of 4-6-year-old children suffering from autism spectrum disorder. The research design was semi-experimental with pretest-posttest and a control group. 30 qualified children (15 males and 15 females) were randomly selected from 4-6-year-old children of Isfahan city in 2015 by convenience sampling method and assigned to experimental and control groups. Data were collected by Gesell Motor Developmental Scale (1940) completed by parents in pretest, posttest and follow-up. Then, experimental group received ten 90-minute treatment sessions once a week in which children participated in play-based early intervention. Control group received no treatment. Follow-up was conducted 30 days later. Data were analyzed using analysis of variance with repeated measures. Results indicated a significant difference between experimental and control groups in psychomotor development. Moreover, intra-group differences, the interaction between two positions and changes in pretest, posttest and follow-up were significant in psychomotor development. Therefore, it can be concluded that play-based early interventions influence psychomotor development in children with autism spectrum disorder. Such interventions can be applied to improve and enhance these children’s skills.

Este artigo descreve as condições do surgimento e da construção de um novo recurso territorial local baseado no desenvolvimento da presença das dunas de areia. Merzouga, no deserto pré-sahariano do sudeste do Marrocos, tornou-se assim um centro mundial do turismo no deserto. A imersão turística na areia (ou o psamoturismo) é em dobro : um turismo de excursão clássico para uma clientela internacional e um turismo de bem-estar que consiste, para os curistas marroquinos, na prática de banhos de areia. O recurso arenoso está vinculado a outros recursos, culturais e identitários, que o ancora localmente e o torna um recurso territorial específico, reconhecido do exterior e controlado localmente. A massificação do psamoturismo, especialmente através da criação de uma “frente do deserto”, ameaça com a banalização dos recursos que marcaram a especificidade e o sucesso deste destino turístico.

The first appearance of the daily newspaper Politika in Belgrade, in January 12th, 1904, marked a great step toward independent journalism in the Kingdom of Serbia. During its first two years of publishing, Politica delivered judgments and reportages on concerts that have been taking place in Belgrade. Articles have evolved from the announcements of concerts into a detailed accounts of the events enriched with interesting details about performed works and performers. From them it is seen that the musical life in Belgrade was extremely rich, and that various ensembles, orchestras and soloists, both from the country and abroad were performing in numerous cultural institutions.The aim of the paper is twofold. Firstly, to present musical criticism in the first two years of publishing Politika, both chronologically and systematically, in order to provide insight into the mainstream of critical thinking and developing of the musical criticism. Secondly, to provide the better understanding of the cultural, i.e. musical life in the capital of Serbia in the observed period. The main contribution of the research lays in its methodological approach, according to which there is no essential difference between the nature and the methods of musical criticism and musical history, which is seen as diachronic criticism. Furthermore, music history is considered as a totality of musical culture of the time. In this view each data, indirect reference, and literary source can be beneficial and useful for musical history. The implication of the work is the necessity of further research which would contribute to Serbian music historiography and bibliography.

Este estudo investigou os efeitos do treinamento em corrida de baixa intensidade (TCBI) sobre propriedades estruturais e mecânicas da epífise proximal do fêmur de ratas osteopênicas. Ratas Wistar [idade = 20 semanas; massa corporal = 271,42 ± 17,6 g] foram submetidas à ovariectomia (OVX) ou laparotomia (SHAM) e alocadas em quatro grupos: corrida OVX (CO, n = 12), controle OVX (CONO, n = 12), corrida SHAM (CS, n = 12) e controle SHAM (CONS, n = 12). Quinze dias pós-cirurgia, os grupos CO e CS foram submetidos ao TCBI em esteira (16 m/min, 60 min/dia, cinco dias/semana) por 10 semanas. O TCBI não alterou os efeitos deletérios da osteopenia induzida por ovariectomia sobre a densidade mineral do fêmur, a quantidade de osso trabecular no trocanter e colo do fêmur, a tenacidade e a força máxima de fratura do colo do fêmur de ratas.
