Mn-doped PbSnanocrystalline thin films of three different dopant concentrations of 1 wt.%, 1.5 wt.% and 2 wt.% Mn were deposited onto glass substrates at 313K by Chemical Bath Deposition Method (CBD) using lead acetate and thiourea as precursors with Manganese acetate as dopant precurser. The as prepared thin films were characterized by using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and Energy Dispersive X-ray (EDAX). Analysis of energy dispersive X-ray confirmed the presence of Pb, Mn and S elements. The particle size of the prepared nanoparticles decrease with the increase of dopant concentrations.For 0 wt.%, 1 wt.%, 1.5 wt.% and 2 wt.% Mn dopant concentrations, the average crystallite sizes were found to be 21 nm, 17 nm, 14 nm and 11 nm respectively. The decrease in crystallite size with the increase in dopant concentrations may be due to the replacement of larger radius lead ions by the smaller radius Mn ions.

Published: February 2023

Objective

Linear growth is impaired in children with type 1 diabetes (T1D) and poor metabolic control. A good metabolic control is a key therapeutic goal to prevent vascular complications and also to ensure appropriate anthropometric development during childhood. In this study, we aimed to identify and characterize the effects of glycemic variability on linear growth in children with T1D.

Methods

Data from 144 prepubertal children with T1D were evaluated. Anthropometric measurements (weight, weight-SDS, height, height-SDS, BMI, BMI-SDS) were collected and glycosylated hemoglobin (HbA1c) was measured at admission and every 4 months over a 2-year period. Glycemic variability indexes (glycemic coefficient of variation (CV), glycemic CV percentage (CV%), and the product between HbA1c-mean and HbA1c-SDS/100 (M*SDS-HbA1c/100)) were calculated. According to height-SDS changes after 2 years of follow-up, the study population was divided into three tertile groups and differences across groups were investigated for variables of interest.

Results

The three groups were similar in terms of age, gender, and follow-up period. After 2 years, all prepubertal children showed a significant positive trend of anthropometric data. Across the three tertile groups, HbA1c-SDS, CV, CV%, and M*SDS-HbA1c significantly decreased from the first to the third tertile of height-SDS. During follow-up, children with lower Δheight-SDS values reported higher values of HbA1c-SDS, CV, CV%, and M*SDS-HbA1c than subjects with higher linear growth.

Conclusions

Glycemic variability correlates with linear growth in children with T1D. Low glycemic variability indexes were reported in higher height-SDS tertiles. Δheight-SDS is inversely correlated with glycemic CV, CV%, and M*SDS-HbA1c.
Relic Particle Production
Authors: Valenzuela Mississippi
Published: February 2023

The last few decades have seen an explosive increase in the amount and precision of data obtained from cosmological observations. Theoretical cosmologists have not yet finished interpreting this amount of data. Likewise, the wonderful ideas we have for the beginning of the Universe have not yet been connected with concrete models of elementary particles. Currently, the existence of dark matter (DM) is accepted in the scientific community. Stars, planets, comets, cosmic dust and other forms of matter make up 5% of the matter in the Universe. The remaining 95% would be "dark matter" and "dark energy", if it is that, it is not known what it is, in fact they exist. In this work, the standard cosmological model is studied, as well as the production of relic particles with the Boltzmann equation applied to the decoupling of relic particles from a reservoir.

El sitio arqueológico Pampa la Cruz está situado sobre una terraza marina, a 200 metros del litoral del distrito de Huanchaco en la ciudad de Trujillo. Por la importancia de este complejo arqueológico, uno de los grandes retos es el estudio de sus pinturas murales y pigmentos para su preservación. En función de esta perspectiva, la presente investigación fue desarrollada con el propósito de estudiar y determinar cualitativa y cuantitativamente la composición mineralógica de los pigmentos de mural por difracción de rayos X de polvo y, de esta forma, determinar la presencia de agentes degradantes. El análisis cuantitativo fue realizado por el método de Rietveld, a fin de obtener información sobre los parámetros estructurales y el porcentaje en peso de cada fase identificada. Fue determinada la composición mineralógica de los pigmentos, encontrándose un alto porcentaje de cuarzo, diversas arcillas como fases minoritarias y sal halita; esta última en pequeña proporción y como contaminante externo. Se espera que estos resultados contribuyan con la preservación, restauración y mantenimiento de este sitio arqueológico.
Methods for the solution of systems of nonlinear algebraic equations and functions’ minimization tasks: elements of theory and applications
Authors:   Institute of Cybernetics of National Academy of Sciences of Ukraine, Zadiraka Valery Konstyantynovich
Published: February 2023

Due to the rapid development of modern telecommunication and information technologies, there is a great need to develop new and improve existing methods for signal demodulation, information encoding and decoding, automatic objects’ recognition etc. A large number of these tasks is reduced to solving systems of nonlinear algebraic equations and problems of minimizing functions. The monograph presents the methods of localization of all the roots of nonlinear algebraic equations systems based on Jacobian’s non-degeneracy, Kantorovich’s theorem, and Krawchyk’s operator are developed. Based on the method of searching all the roots of systems of nonlinear algebraic equations, the method of global minimization of functions of many variables is developed. Also, based on the developed methods and autoregressive model of speech, the new efficient high-speed methods of calculating the immittance spectral frequencies of speech signals have been developed. It is shown that the method has higher computational efficiency over the methods used in existing communication systems. Conditions for orthogonality and minimization of the Riesz ratio for wavelets based on Jacobi polynomials are established. Basing on maximizing a posterior probability function, the method of demodulation and estimation of channel parameters on the basis of particle filtering is developed, the method of demodulating signals with a continuous phase is developed, which is based on the use of signal phase values only and the method of blind separation of signals with amplitude-phase modulation. It is shown that the proposed particle filtering demodulator provides an advantage over standard demodulators based on the use of Gardner and Costas loops. The developed method of demodulation of signals with a continuous phase has shown greater resistance to phase and frequency distortions of the signal in the communication channel as compared to the traditional demodulator. The method of semi-automatic data classification based on the minimization of Tikhonov functional using discrete Laplacian and the quasi-optimal choice of the regularization parameter has been developed and verified for different data sources. Also a new computationally efficient method for automatic identification of the speaker’s gender based on the Gaussian mixture models was developed based on the maximization of likelihood function. This method is based on the use of information vectors consisting of the pitch period of the speech signal and the set of cepstral coefficients.

James-Stein type estimators in beta regression model: simulation and application
Authors: SEİFOLLAHİ Solmaz , BEVRANİ‎ Hossein
Published: February 2023

Recently, the beta regression model has been used in several fields of science to model data in the form of rate or proportion. In this paper, some novel and improved methods to estimate parameters in the beta regression model are proposed. We consider a sub-space on the regression coefficients of the beta regression model and combine the unrestricted and restricted estimators then we present Stein-type and preliminary estimators. We develop the expressions for the proposed estimators' asymptotic biases and their quadratic risks. Numerical studies through Monte Carlo simulations are used to evaluate the performance of the proposed estimators in terms of their simulated relative efficiency. The results show that the proposed estimators outperform the unrestricted estimator when the restrictions hold. Finally, an empirical application is given to show how useful the proposed estimators are in the practical area.
Exploring intervention of e-textbook in schools: Teachers’ perspectives
Authors: Alibrahim Amal , Alsadoon Elham
Published: February 2023

As an innovative educational tool, e-textbooks has gained wide interest – especially with the growth of e-learning. As with any new technology, understanding how users adopt these technologies is still unclear. In the study reported on here we proposed a theoretical model shaping the determinants of teachers’ attitude toward e-textbooks. Specifically, we identified three contextualised factors (ease of use, usefulness, and concerns) as the factors of adopting e-textbooks. In addition, we examined teachers’ use of e-textbooks. A mixed-methods research design was used in which quantitative and qualitative data were collected and analysed. The results show that teachers held positive attitudes toward using e-textbooks in their teaching and used them as instructional aids. The results might inform education decision-makers who are planning to integrate e textbooks into their schools in line with digital transformation and the knowledge society.
Dlaczego nie lubimy biografii dotyczących osób z czasów PRL?
Authors: Eisler Jerzy
Published: February 2023

The first twenty-five years of the Third Polish Republic saw only a few – well or not so well written – monographs devoted solely to important and significant political figures of that time. Monographs with their clear structure – a description of a person’s life from birth to death – are preferred choice of researchers as well as the wider audience of history lovers. These books feature a person against the historical background of a particular epoch and it is therefore essential to keep the right proportions between a personal story and the historical background. Finally, – and in my opinion this is probably most important – distinguished individuals, who in general feature as the main characters of biographies, grasp readers’ attention because the question whether it is an individual who shapes the reality or rather the rather way round, always remains valid. Without biographies then, it would probably be impossible to explain certain issues, phenomena and events.

This paper discusses the status of literary biographic studies at the turn of the 21th century in Poland. It points out to how the methodological transition in literature studies influenced changes in literary biographic studies, namely the weakening impact of structuralism and the introduction of new scientific paradigms. The question how the convention of describing characters in other human and social sciences, i.e. history, psychology, sociology and philosophy, influenced the position and concept of literary biographic studies, is also discussed.

The article discusses the archivist angle of work, i.e. the acquisition of data and materials necessary to bring together different pieces of occupation-time life of Jakub Laskiera. Jakub Laskier was a Polish assimilated Jew, an educated banker and a Zionist (he spent some time in a kibbutz in Degania Alef, Palestine, and was a member of Aron Gordon’s group). He was in Auschwitz and Sachsenhausen concentration camps during the Holocaust and took part in a secret mission called the “Bernhard’s operation”, the historical value of which is worth recalling.
„Eugeniusz Kwiatkowski o Szczecinie i Pomorzu Zachodnim”
Authors: Drozdowski Marian Marek
Published: February 2023

Eugeniusz Kwiatkowski (1888–1974) created the maritime policy of the Second Polish Republic. Before the war, in 1926–1930 and 1935–1939, he had a significant impact on the Polish economic policy. At that time, he saw Szczecin mostly as a competitor for the Polish free-trade harbour zone (Gdańsk & Gdynia) and the West Pomerania region as an exploiter of cheap Polish labour force in their local estates. The post-war boarder changes obviously changed his views. Kwiatkowski became one of the most important supporters of the reconstruction of Szczecin’s harbour, connecting the city and the region to the rest of the country by building infrastructure, and establishing a genuine maritime academy. The plans drawn up in the first post-war years were in large parts abandoned. The West Pomerania region and its neighbourhood, however, remained an important part of Kwiatkowski’s views on modern policies.

Published: February 2023

Abstract: Chuang Tzu (《庄子》), as a traditional Chinese canon, has been translated into English for more than 100 years since 1881, successfully carving a niche in the realm of world literature, which has become an earth-shattering cultural event in the academia of overseas sinology and world literature. According to statistics, the book has been translated into 12 full translations, 50 selected translations, and two adaptations. The metamorphosis process of “full translation - deep translation - diversified retranslation”, has passed through four stages, namely religious, literary, philosophical, and diversified reinterpretation phases. Thus, from the perspective of Damrosch’s view of world literature, this paper summarizes the characteristics of different stages based on different spatial-temporal contexts. In the light of translation form, translational outcomes, and translation mode of reading, the path in which Chuang Tzu entered into the field of world literature is specified for the operational mechanism of promoting national literature to world literature, which is dedicated to the enlightenment for practical translation work of introducing Chinese literature abroad. Meanwhile, by reviewing the history of English translations of Chuang Tzu, this paper sums up the deficiencies of current translation activities and research activities, with an attempt to provide constructive suggestions as well as to point out the direction for the future development of overseas studies of Chuang Tzu.

This study aimed to estimate the prevalence of psychoactive substance use by adolescents from public schools. This is a cross-sectional study that used a random sample of adolescents from five public schools located in a municipality in the central-west region of the São Paulo Metropolitan Area, Brazil. Information on demographic, socioeconomic, and drug use was collected using self-report questionnaires. The sample consisted of 1,460 students, 716 (49%) males, aged 10-19 years (13.19±2.04 years). The prevalence of psychoactive substance use in the last month was 51% for analgesics; 48.8% for alcohol; 37.3% for tobacco; 30.8% for tranquilizers; 23.1% for marijuana; 22.6% for anabolic steroids; 21.6% for ecstasy; 15.3% for amphetamines/stimulants; 13.4% for phencyclidine; 12.9% for cocaine/crack; 12.6% for inhalants/solvents; 11.5% for opiates; 11.4% for hallucinogens; and 16.2% for other unclassified drugs. Elementary and middle school students were more likely to consume tobacco (OR = 2.306; 95%CI: 1.733-3.068; p < 0.001), and male students were more likely to consume any type of substance. We identified a high use of psychoactive substances among this study participants, with a higher prevalence among male students.

Published: February 2023

ABSTRACT The aim of this study is to analyze the evolution of the implementation of the School Health Program (PSE) over its 15 years in Brazil. A mixed methodological approach was used, involving a combination of document analysis and ecological study with secondary data from 2007 to 2021 recorded in the historical process of implementing the PSE in Brazil. It was observed that in these fifteen years the PSE has advanced not only significantly impacting the percentage of municipalities that joined the Program, but also in its structure and format, having the territory as the main locus of its development, and the articulation between health and education as the driving strategy of local arrangements. Furthermore, the PSE’s intersectoral management model helps the articulation of health and education networks in an interfederative manner. Therefore, this historical analysis gives an overview of school health in Brazil from the perspective of the PSE and provides the perspective of improvement necessary for the sustainable and qualified continuity of the Program.
Youth participation in the Scholl Health Program in Brazil: a reflection on the role of the Federal government
Authors: Bueno Denise Ribeiro , Köptcke Luciana Sepúlveda
Published: February 2023

ABSTRACT This article reflects on youth participation in the PSE, through the conceptual and operational analysis of the idea of participation in its technical and normative frameworks. It also questions whether the PSE maintains, reduces, or improves youth participation, when comparing it to the Health and Prevention in Schools Project, a precursor of the program. The school, a place that contributes to the formation of the individual, according to guidelines established by law, must promote these spaces for participation, strengthening students in a perspective of recognition of the importance of involving this public in discussions of healthy lifestyles, considering that the PSE works from the perspective of Health Promotion. From the qualitative discussion, carried out through documental and bibliographic analysis, as well as the literature review, it was identified that youth participation was one of the pillars of the SPE, a project whose actions were incorporated into the PSE, but which lost strength by not being promoted within the scope of the Program’s legal instruments. The qualification of dialogue among all members of the school community, including one of the Program’s largest target audiences, the youth, strengthens the recognition of the territory as a central actor in the implementation of social policies.

RESUMO O Programa Saúde na Escola tem como meta a construção de escolas saudáveis. Estudo de caso, de abordagem qualitativa com intenção de identificar e compreender como se comportam, no esforço de integração, profissionais envolvidos no Programa Saúde na Escola, a partir de sua inserção nas atividades preconizadas. Após construção do modelo lógico do programa, foi realizado consenso com experts para elaboração de matriz de indicadores, originando roteiro semiestruturado. Foram realizadas 25 entrevistas, nas Unidades Básicas de Saúde e Escolas de Ensino Fundamental, além das Gerências Regionais da Saúde e da Educação. As práticas foram consideradas multissetoriais, sem soma de esforços e coparticipação efetiva, sendo planejadas por um único setor ou profissional; os gaps existentes são reconhecidos tanto quanto a importância do programa; as práticas acontecem com baixo vínculo entre equipes. A forma fragmentada de perceber os problemas dos escolares dificulta essa integração.

RESUMO Estudos trazem contribuições sobre o Programa Saúde na Escola, mas poucos investigam o processo de trabalho dos profissionais, a fim de compreender se existe a conformação de projetos intersetoriais e integrados ou tecnologias como mediadoras nas práticas de trabalho. O presente estudo buscou analisar as práticas dos profissionais em uma Unidade de Saúde da Família, em Salvador-BA. Este estudo de caso, de abordagem qualitativa, envolveu uma Unidade de Saúde e quatro escolas. Os procedimentos para coleta de dados compreenderam entrevistas semiestruturadas, análise documental e observação participante. A construção das categorias de análise ocorreu a partir do referencial teórico do processo de trabalho em saúde de Mendes Gonçalves. Os resultados demonstraram: fragilidades nas relações de parceria entre os agentes; percepção do objeto de trabalho pelos profissionais, predominantemente, como identificação de doenças e saber clínico preponderante em relação ao saber da saúde coletiva. As ações de saúde aproximaram os agentes, mas apresentaram práticas hegemônicas, desarticuladas, setoriais, focadas na doença e executadas, principalmente, por meio de palestras. Não existem projetos integrados e intersetoriais ou tecnologia educacional como recurso auxiliar nas práticas de trabalho. Os produtos, resultantes da participação de todos, trarão contribuições para melhor articulação entre os profissionais que atuam nesses espaços.

RESUMO O estudo objetivou compreender as potencialidades e os limites da articulação intersetorial do Programa Saúde na Escola para a promoção da saúde infantil, sob a ótica dos profissionais da atenção primária. Pesquisa de abordagem qualitativa, descritiva-exploratória, realizada com 20 profissionais da área da saúde, residentes em quatro municípios da Região da Grande Florianópolis. A coleta de dados foi desenvolvida por meio de entrevistas, no período de novembro de 2020 a março de 2021. Os dados passaram por análise de conteúdo e discutidos à luz do referencial teórico da promoção da saúde. Destacaram-se, como potencialidades, o acompanhamento das condições de saúde dos escolares, a ampliação do acesso à informação, a parceria com outros setores e a criação de vínculos com a comunidade escolar. Os limites evidenciados foram a cobertura parcial da rede escolar, o desconhecimento sobre o programa, a sobrecarga de atividades, os impactos causados pela pandemia da Covid-19, a falta de recursos humanos e de infraestrutura. Conclui-se que há necessidade de fortalecimento do Programa Saúde na Escola enquanto política pública, com vistas à efetivação de ações articuladas entre saúde e educação para o alcance da melhoria da qualidade de vida dos escolares, com atuação sobre os seus determinantes sociais.

ABSTRACT The promotion of physical activities is one of the 13 actions of the School Health Program. This study aims to describe the actions of body practices and physical activity registered in three accession cycles (2014-2015, 2017-2018, and 2019-2020) by region and Federative Unit (FU). Using descriptive analysis, the number of actions, in each year, cycle, FU, and region were presented. In all regions, the number of municipalities and schools adhering increased in each cycle. When considering the total number of municipalities of each region, 100% of the Northeast region municipalities adhered to the program in the last two cycles. The Southeast region had the lowest proportion of municipalities that adhered to all the cycles. In most FUs, in each cycle, the majority of actions were conducted in the first year. Nationally, there was an increase in the number of actions in all the cycles, mainly in the Northeast and Southeast. From the first to the third cycle, this increase was higher in the Southeast and South. Minas Gerais, Bahia, Ceará, and Maranhão comprised almost half of the actions. The results showed different nuances in the implementation of the promotion of physical activity and can technically subsidize the managers and technicians linked to the program.
O luto da ciência ideal
Authors: Beer Paulo
Published: February 2023

Resumo A ciência moderna tem sido objeto de idealizações desde sua emergência, as quais parecem perdurar mesmo após revisões e críticas presentes na filosofia da ciência contemporânea. Isso indica que parte das tentativas de readequação da imagem que se constrói sobre a ciência - e dos discursos que circulam sobre ela - não parece ter efeito. Propomos, neste artigo, que essas dificuldades resultam, em parte, da complexidade em lidar com os investimentos libidinais dos processos de idealização. Isso é indicado com base na teoria psicanalítica e na filosofia da ciência, sendo seguido por um trabalho conceitual sobre os mecanismos atuantes em processos identificatórios e nos possíveis efeitos da perda de um ideal, sustentando a necessidade de realização de um luto. Assim, afirmamos que desidealizar a ciência é, sobretudo, uma maneira de fortalecê-la.

ABSTRACT: Water scarcity associated with irregular rainfall in the semi-arid region of Northeastern Brazil stands out as a limiting factor for agricultural production. Thus, the use of waters with high concentration of salts is an alternative to expand irrigated agriculture in this region. In this context, this study evaluated the water status, intercellular electrolyte leakage, photosynthetic pigments, and gas exchange of ‘BRS SC1’ sour passion fruit as a function of irrigation with water of different levels of salinity and potassium doses. The experiment was carried out in pots adapted as drainage lysimeters under field conditions at the Experimental Farm of the Federal University of Campina Grande in São Domingos - PB, Brazil. The experimental design was randomized blocks, in a 5 × 4 factorial scheme, whose treatments were obtained by combining two factors: five levels of electrical conductivity of irrigation water - ECw (0.3, 1.1, 1.9, 2.7, and 3.5 dS m-1), associated with four potassium doses (60, 80, 100, and 120% of the recommendation), with three replicates. Water with electrical conductivity greater than 0.3 dS m-1 reduced the relative water content, chlorophyll a and chlorophyll b contents, CO2 assimilation rate, and instantaneous water use efficiency of ‘BRS SC1’ sour passion fruit plants. The estimated potassium dose of 85% of the recommendation (equivalent to 293 g per plant per year) mitigated the deleterious effects of salt stress on stomatal conductance, transpiration, internal CO2 concentration, and instantaneous carboxylation efficiency of passion fruit ‘BRS SC1’.

ABSTRACT: The growing worldwide demand in the pulp market has fostered research that evaluates alternative fiber sources with specific characteristics that attend the needs of the consumer market, with a view to add value to the final product and reduce production costs. Acacia mearnsii De Wild wood is a by-product of the extraction of tannin from the trunk bark, used for firewood, charcoal and pellets. However, its wood is still poorly studied, especially its anatomical characteristics, which can provide important information about its industrial potential. This study evaluated the anatomical characteristics of Acacia mearnsii wood for the production of pulp and paper. Ten trees at approximately seven years old were cut down, five from the seed production area (SPA) and five from the clonal population area (CPA). From each tree, one trunk disc was sectioned at the diameter at breast height (DBH), resulting in 10 (ten) wood samples. From each disc, a sapwood specimen was made oriented in the tangential longitudinal, radial longitudinal and transversal planes, for later obtaining the anatomical cuts and the macerates. The anatomical description of the wood followed the recommendations of the International Association of Wood Anatomists-IAWA. From the dimensions of the fibers, their quality evaluation ratios for the production of pulp and paper were calculated. Results obtained from the anatomical characterization allowed to conclude that the Acacia mearnsii woods from SPA and CPA are indicated as a source of raw material for the pulp and paper production.

Published: February 2023

ABSTRACT: This article analyzed the international competitiveness of exports of forest products from 2008 to 2018. The information is available in the Food and Agriculture Organization (FAO) and the indicators used were: revealed comparative advantage (RCA), trade openness index (Oi) and the contribution to trade balance index (CTB). Results showed that the exportation of forest products are competitive, in addition gains in competitiveness have been observed by the RCA and in Europe, countries had losses in detriment of the financial crises and austerity measures adopted. All countries showed a low degree of openness by the Oi and had a comparative advantage by the CTB, except for China and Germany. It is concluded that the countries with bigger comparative advantages in the exportation of forest products were the ones that had contributed more for its commercial balance.

ABSTRACT Introduction: Gymnastics requires high-level body coordination and control. The key to success for gymnasts is to control and adjust the center of gravity through the abdominal core muscles. Abdominal core resistance training is mainly aimed at fulfilling this purpose. Objective: Analyze the results of abdominal core resistance training on the fitness of gymnasts. Methods: 20 volunteer gymnasts were selected by random sampling. The experimental participants were tested for functional exercise capacity. The study focused on the athletes' weaknesses during exercise. After completing the abdominal core resistance training, the fitness test was performed. The data obtained were analyzed statistically. Results: The peaks of the flexor and dorsal muscles were significantly enhanced (P<0.05). There was no significant difference between the two groups before and after training of body flexors and extensors (P>0.05). Conclusion: Abdominal core resistance training plays a positive role in improving the fitness of gymnasts. Coaches can actively introduce abdominal core resistance training into their regular exercises to improve athletes' fitness.

ABSTRACT Introduction: Chinese basketball players have poor lower limb strength, and their movements may be distorted due to insufficient explosive strength in hostile environments. This will cause basketball players to make mistakes. Objective: Evaluate the effect of resistance training on lower extremity explosive strength in basketball players. Methods: 18 basketball players were selected by random sampling. The volunteers were randomly divided into the experimental and the control group. The experimental group used the resistance and routine training protocol for 12 weeks. The data were analyzed employing mathematical statistics. Results: There was no significant difference between the experimental and control groups regarding age, height, weight, and years of training (P>0.05). After explosive training, the standing jump performance of both groups of athletes improved, but the experimental group’s performance improved significantly (P<0.05). After explosive training, both groups significantly improved the vertical jump in situ, with higher intensity in the experimental group (P<0.05). The performance of the 30-meter start improved in both groups after explosive training. Conclusion: The presented protocol for resistance training on the lower extremity has a very significant effect in improving the performance of basketball players.

Published: February 2023

ABSTRACT Introduction: Suspension training is a new activity in which exercises are performed exploring the body weight as resistance, using a suspension tape. The body remains in constant motion due to the support reaction force formed by the open kinetic chain, requiring rapid muscle contractions for continuous balance adjustment. It is believed that this training can improve proprioceptive neuromuscular function, although there is little scientific evidence of its benefits on body posture in athletes. Objective: Explore the function and application of the overhead training method in athletes. Methods: Sixteen male athletes from a provincial badminton team volunteered for the research. Divided into two groups, the experimental group added suspension training. In contrast, the control group kept only traditional training, the other training contents were the same between the two groups, and the experiment lasted 12 weeks. The relevant data were collected before and after the intervention period by the GoodBalance balance tester, and the balance ability of all athletes with eyes closed on one foot was evaluated. Results: The balance ability of the athletes in the experimental group was significantly improved, while the balance ability of the athletes in the control group changed little. Conclusion: Suspension training can significantly improve the balance ability of athletes and can be used as an effective auxiliary training method for balance improvement. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

ABSTRACT Introduction: Chinese boxing demands the maximum potential from its practitioners. The quality of executions of single or multiple punches depends on adequate strength training, and the quality of speed is a crucial factor for victory in Chinese boxing competitions. Objective: Explore the effects of strength training on the speed of punches in Chinese boxing athletes. Methods: Eighteen Chinese boxers were selected by random sampling. The competitors perform functional exercises directed at strength training for ten weeks. Several key points of sports aerobics were comprehensively evaluated. Mathematical and statistical methods were applied in processing the data before and after the intervention. Results: The speed quality of Chinese boxing practitioners after strength training was statistically beneficial (P<0.05). Only the particular qualities of strength did not show significant differences among the four unique qualities of strength analyzed; there were significant differences among the other three abilities (P<0.05). Conclusion: The introduction of functional strength training into the physical training of high-level Chinese boxing athletes can significantly improve the quality of movement speed. Functional strength exercises are a safe and efficient form of exercise. This training protocol provides a good reference to compensate for the shortfall in conventional strength exercises.
