Authors: Zhang Hui , Zhu Mingjiang , Li Yuanjing , Zhang Chengyun , Bie Yejun , Liu Haishan
Published: February 2023

ABSTRACT Introduction: Cherry extract has a high amount of anthocyanins and flavonoids containing antioxidant effects. Its high antioxidant characteristics have been shown to reduce markers of delayed muscle soreness (DOMS) and exercise-induced muscle damage (EIMD) to improve recovery after exercise. Objective: Verify the effects of the cherry extract on post-exercise muscle damage. Methods: Google scholar, Medline, and Scopus were systematically searched until February 2022. The Cochrane Collaboration tool was applied to determine the risks of bias. Results: The results showed that cherry extract administration did not have a decreasing impact on creatine kinase levels overall: (WMD = 12.85 IU. L-1, 95% CI: −35.94, 61.64; P = 0.606). Considerable heterogeneity was observed among the articles (Cochran's Q-test = 990.80, P = 0.000, I2 = 96.7 %). However, there is a significant reducing effect on pain sensation by the consumption of cherry extract (WMD = −6.105 mm; 95% CI: −11.193 −1.017; p = 0.019). Conclusion: Cherry extract consumption effectively reduced late-onset muscle pain among participants in the overall and subgroup analysis. Thus, the cherry extract may be a complementary alternative in recovery after exercise. Level of evidence II; Therapeutic studies - Manuscript review.

Published: February 2023

ABSTRACT Introduction: Attention is given to developing electrochemical sensors for the rapid and real-time measurement of lactate levels. The synthesis of electrochemical sensors is based on an electrode modified with a nanocomposite. Objective: Analyze an electrochemical sensor's feasibility for sports monitoring sweat in lactate. The Au@CNTs were the main focus of this study. Methods: The Au@CNTs composite was synthesized on the GCE surface and tested under pre-established protocols as a sensor. Results: The shape and structure of the modified electrodes were analyzed using SEM. The results showed that the Au@CNTs nanoparticles in the Au@CNTs nanocomposite were evenly distributed throughout the porous CNTs network. The performance of the developed sensor was measured using cyclic voltammetry and amperometry. The electrochemical biosensor responded linearly to lactate over phosphate buffer solution with a low detection limit and sensitivity. Conclusion: The experiment of this sensor evaluated lactate concentrations in real sweat samples that were exceptionally close to the injection amount, enabling it as an effective biosensor for the detection of lactate in sweat samples.

Published: February 2023

ABSTRACT Introduction: Identifying and measuring the concentration of Triamcinolone (TA) in biological fluids is essential, especially for patients receiving intensive antibiotic medication. Objective: Make a sensor for electrochemical detection of Triamcinolone (TA) as an anabolic steroid in sports using copper oxide nanomaterials-reduced graphene oxide nanoparticles (CuNPs/rGO). Method: After preparing rGO nanoparticles on a glassy carbon electrode (GCE) using the modified Hummers technique, Cu NPs were deposited on rGO/GCE. The applicability of Cu NPs/rGO/GCE was investigated to determine the TA concentration in a real sample that had been prepared. Results: The deposited irregular Cu NPs evidenced a diameter of about 80 nm, in agreement with SEM morphological investigations. Amperometric studies revealed that the linear range, detection limits, and sensitivity of CuNPs/rGO/GCE as a TA sensor were 10 to 80 µM, 10nM, and 0.06584 µA/µM, respectively. Conclusion: The results revealed that the RSD and recovery values were valid, providing adequate quality and reliability for practical analysis of real samples using Cu NPS/rGO/GCE.

Authors: Wang Wenping , Wazir Mohd Rozilee Wazir Norjali , Geok Soh Kim , Gao Yongqi , Xiong Wei
Published: February 2023

ABSTRACT Introduction: Prednisolone causes pro-inflammatory impulses to be inhibited and anti-inflammatory signals to be promoted. As a result, it alters how the body's immune system reacts to certain diseases. The World Anti-Doping Agency, however, has banned SNP and other glucocorticosteroids. An electrochemical sensor can be developed using a gold nanocomposite, polypyrrole nanoparticles and synthesized carbon nanotubes (Au-PPy NPs@CNTs). Objective: Develop an electrochemical sensor to detect prednisolone. Method: Au-PPy NPs@CNTs nanocomposite was chemically synthesized with a modified glassy carbon electrode (GCE) surface. Results: According to SEM data, the nanocomposite was composed of amorphous Au NPs, and PPy NPs deposited in tubes strongly entangled in a CNTs network. The wide linear range and low detection limit of the Au-PPy NPs@CNTs/GCE as prednisolone sensors were attributed to the combined catalytic performance of the Au and PPy NPs@CNTs nanostructures. Conclusion: The results of prednisolone detection in each specimen using the amperometric method indicated good accuracy. The accuracy and precision of Au-PPy NPs@CNTs/GCE for prednisolone detection were explored in blood samples from 5 young athletes aged 20-24 years who used prednisolone tablets (RSD less than 4.25%). In addition to monitoring prednisolone concentrations in athletes’ serum, Au-PPy NPs@CNTs/GCE can be used as a reliable prednisolone sensor.

TESTOSTERONE BIOSENSOR IN SPORTS DOPING
Authors: Ni Zhiwei
Published: February 2023

ABSTRACT Introduction: Testosterone is a steroid that can help with blood disorders, sexual dysfunctions, connective tissue diseases, some malignancies, intractable pain, and other serious diseases. However, it must be prescribed under medical supervision because of the risk of major adverse effects such as liver disease, heart disease, stroke, blood clots, and cancer. There is an urgent need for research on developing an electrochemical sensor to detect testosterone as a doping substance in sports. Objective: Develop an electrochemical sensor of poly(ionic liquid)-graphene oxide molecularly printed polymers (PIL/MIs/GO) to detect testosterone as a doping substance in sports. Methods: Morphological characterization of modified electrodes was performed by field emission scanning electron microscopy (FESEM), allowing the GO to be surface-mounted with fragments and apertures. Due to the holes generated by the agglomeration of PIL and MIs molecules on the wavy edges of the GO nanosheets, the surface morphology of PIL/MIs/GO/GCE also revealed a high porosity structure. Results: Compared to other synergistic influences of GO nanosheets with PIL and MIs molecules, electrochemical investigations using a differential pulse voltammetry approach indicated high selectivity, good stability, appropriate linear range, lower detection limit, and higher selectivity. Conclusion: In pharmaceutical samples and human biological fluids, the validity and accuracy of PIL/MIs/GO/GCE for the determination of testosterone demonstrated practical application. PIL/MIs/GO/GCE can thus be used as an accurate and reliable sensor for detecting testosterone as a doping agent in sports.

ABSTRACT Introduction: CrossFit was created to develop the physical and motor skills of athletes in all categories, aiming for the physical limit of everyone who practices it, in accordance with their toning capacity. Objectives: Considering that the quest for these limits has resulted in an increasing number of CrossFitter injuries, the objective of this study was to define the levels of pain and the anatomical regions affected among CrossFitters in the city of Alfenas. Methods: The Corlett diagram was used in association with the Visual Analog Scale, which ranges from 1 to 10. Three CrossFit gyms in the city of Alfenas were visited and their CrossFitters were invited to participate in this research. Those who agreed to participate (109) signed the informed consent form. Results: Of the total number of participants interviewed, 86.63% reported having some type of pain in their daily CrossFit routine. Of the total number of respondents who experienced pain, 56.68% were women and 43.32% were men. The three areas that stand out with the highest prevalence of pain were shoulders at 51.37%, the lower back at 44.03%, and the knees at 40.36%. The One-way ANOVA test was applied with p≤ 0.05 and there was no statistical difference between the pain groups (trunk pain, right limb pain, and left limb pain). Conclusion: When we applied the Corlett diagram to verify the degree and anatomical regions of pain in CrossFitters in the city of Alfenas, it was evident that CrossFit is a sport that, by demanding a lot from those who practice it, ends up causing moderate to severe pain, especially in the shoulder, lumbar, and knee regions.

RESUMO Introdução: A dor lombar é uma das queixas mais comuns nos praticantes de ciclismo. Pode ter como fator predisponente a desarmonia do conjunto ciclista-bicicleta. O Bike Fit é uma técnica que visa ajustar a bicicleta às características individuais do ciclista. Objetivos: Investigar a relação entre o posicionamento do ciclista na bicicleta e a ocorrência de queixas de dor lombar. Métodos: Os dados obtidos durante o Bike Fit de 62 ciclistas amadores foram utilizados no estudo. Os ciclistas foram filmados durante a pedalada em um rolo estacionário e a análise das imagens foi realizada pelo software Kinovea®. Os dados relacionados com a queixa de dor lombar e ao posicionamento na bicicleta foram utilizados no teste do Qui-quadrado e de regressão logística binária. Resultados: A média de idade foi de 38,06 ± 8,82 anos, 87,7% da amostra foi composta por homens e a dor lombar foi constatada em 40,3% (25/62) dos participantes. A análise univariada mostrou correlação positiva entre a dor lombar e as seguintes variáveis: ângulo de dorsiflexão do tornozelo (X2 = 6,947, p = 0,014) e alcance dos membros superiores (X2 = 5,247; p = 0,032). A regressão logística binária mostrou uma associação positiva entre alcance dos membros superiores e dor lombar (r = 2,728; p = 0,002) e associação negativa para avanço dos joelhos e dor lombar (r = -2,281; p = 0,007). Conclusão: Os ciclistas com dor lombar apresentam alterações de posicionamento na bicicleta, o que reforça a importância da avaliação do conjunto ciclista-bicicleta. Entretanto, não é possível afirmar se as alterações de posicionamento observadas na amostra estudada são causas ou consequências da dor lombar.

Published: February 2023

ABSTRACT Objectives: This study aimed to examine the relationship between vertical jumping at forces of specific time phase and sprint performance in teenage sprinters. Methods: Fifteen male teenage sprinters (age: 14±2 years, height: 168±2 cm, weight: 61±1 kg) participated in the study. The subjects performed the following bilateral/unilateral jumps on a force platform: a) squat jump (SJ), b) unilateral SJ (USJ), c) 40cm drop jump (DJ), and d) 20cm unilateral DJ (UDJ). The 60m sprint test was administered on the second day. Brower split timers were positioned to record subjects’ 5m, 10m, 50m and 60m split times. The variables for inclusion were vertical jump height, maximum force, and force output at 120ms in all jumps and sprint time measures. Results: The results of the Pearson Product Moment Correlation analysis showed that SJ120ms was correlated to 5m and USJ120ms was correlated to 10m. UDJ120ms showed a stronger correlation with 50m than DJ120ms. Although significant correlations using maximum force and height were observed, there were inconsistent results between bilateral and unilateral jumps. Conclusion: Our results highlighted that jumps that have similar form with certain force outputs at specific event timing could more precisely predict sprint performance in teenage sprinters. USJ120ms and UDJ120ms could better predict the acceleration (10m) and high-speed phase (50m) in sprint performance, respectively. Moreover, coaches and practitioners should be cautious when using only jump height or maximum force to predict sprint performance, since the results could be inaccurate when specific movement variables are not thoughtfully considered.

ABSTRACT Introduction: Adiponectin plays a significant role in the metabolic system in proinflammatory cytokine inhibition and glucose uptake utilization. The treadmill is an aerobic walking device that stimulates natural walking features. Exercises increase adiponectin levels leading to improvement in insulin sensitivity. Objectives: To analyze the effect of aerobic exercise using a moderate-intensity treadmill with a gradual increase in speed and inclination on adiponectin levels in men with type 2 diabetes mellitus (T2DM). Methods: Twenty-two participants with T2DM were randomized into treadmill exercise and control groups. The experimental group underwent 30-minute sessions of moderate-intensity treadmill exercise with increasing speed and gradual inclination three times a week for four weeks. The control group underwent individual exercise for 150 minutes per week. Participants were assessed for clinical and laboratory parameters before and after the four-week program. Results: There was a significant increase in the adiponectin level from 456.3 ± 42 pg/ml to 586.3 ± 87.8 pg/ml (p=0.04, p<0.05) in the treadmill exercise group. In the control group, adiponectin only increased from 466.7 ± 85 pg/ml to 471.8 ± 59 pg/ml (p=0.646). Conclusions: Moderate-intensity treadmill with increasing speed and gradual inclination was found to lead to a significantly better outcome in improving adiponectin levels than standard individual physical exercise in managing T2DM.

Resumo Objetivo: identificar a situação vacinal e sorológica contra hepatite B entre agentes comunitários de saúde; vacinar contra o vírus da hepatite B e avaliar a resposta imunológica dos agentes susceptíveis. Método: fase I, estudo transversal e descritivo, entre agentes comunitários de saúde de uma capital da região Centro-oeste, por meio de questionário autoaplicável, conferência do cartão vacinal e coleta de sangue para testagem dos marcadores sorológicos para hepatite B. Fase II, estudo de coorte realizado em trabalhadores vacinados não imunes e identificados na fase I. Estes receberam uma dose da vacina (dose desafio) e teste sorológico. Resultados: participaram do estudo 109 agentes. A maioria tinha registro de vacinação (97; 89,0%) e completude vacinal (75; 77,3%), já o marcador anti-HBs (anticorpos contra o vírus da hepatite B) isolado foi detectado em 78 (71,6%) agentes. A prevalência de exposição ao vírus da hepatite B foi de 8,2%. Dos dez agentes vacinados não imunes, após a dose desafio, um permaneceu susceptível. Conclusão: apesar da maioria dos trabalhadores estarem vacinados e apresentarem resposta imunológica para hepatite B, a suscetibilidade após a dose desafio foi identificada. Portanto, é necessário que haja um programa de vigilância da situação vacinal e estado sorológico para este vírus, para promover a segurança destes trabalhadores.

Published: February 2023

Resumen Objetivo: el propósito de este estudio de viabilidad previa fue examinar percepciones y experiencias con respecto a la actividad Sit-to-stand entre los adultos mayores de Brasil que viven en sus hogares en comunidades urbanas. Método: el método de exploración se enfocó en la etnografía. Se utilizó muestreo intencional para reclutar 20 adultos mayores. Se emplearon cinco medios para generar datos, a saber: encuestas sociodemográficas, observaciones participantes, entrevistas informales, entrevistas formales semiestructuradas y notas de campo. Para el análisis de los datos se recurrió a análisis de contenido cualitativo. Resultados: la experiencia de los adultos mayores con problemas de movilidad en relación con la actividad Sit-to-stand dependió de sus expectativas en torno a la movilidad, las cuales implicaron muchos factores que actuaron en conjunto para influenciar sus creencias y actitudes con respecto a la actividad, al igual que preferencias, conductas y percepciones culturales. Aparentemente, a los participantes de este estudio la actividad les resultó amena; sin embargo, los inconvenientes más notorios para adoptar la actividad Sit-to-stand surgió en la forma de déficits en sus necesidades personales e intrapersonales. Conclusión: las recomendaciones resultantes de los hallazgos del estudio indican la necesidad de diseñar estrategias de implementación para la intervención Sit-to-stand a la medida de las necesidades de este grupo poblacional específico.

Resumo Objetivo: o objetivo deste estudo de pré-viabilidade foi examinar percepções e experiências da atividade de Sit-to-stand com idosos brasileiros residentes em suas casas, no meio urbano. Método: o método exploratório foi etnografia focada. Foi utilizada a amostragem intencional para recrutar 20 idosos. Foram utilizados cinco meios de geração de dados: inquéritos sociodemográficos, observações participantes, entrevistas informais, entrevistas formais semiestruturadas e notas de campo. Os dados foram analisados mediante análise de conteúdo qualitativo. Resultados: a experiência dos idosos com problemas de mobilidade na realização da atividade Sit-to-stand dependia de suas expectativas de mobilidade envolvendo muitos fatores coordenados que, de forma conjunta, influenciaram suas crenças e atitudes em relação à atividade, suas preferências, seus comportamentos e percepções culturais. Os participantes deste estudo pareciam considerar a atividade aprazível; no entanto, as deficiências mais perceptíveis para o engajamento dos participantes na atividade Sit-to-stand surgiram de falhas em suas necessidades pessoais e intrapessoais. Conclusão: as recomendações geradas a partir dos achados do estudo convocam a concepção de estratégias de implementação da intervenção Sit-to-stand adaptadas às necessidades dessa população em particular.

Abstract Objective: to analyze nursing technicians’ training in patient safety. Method: a convergent parallel mixed-methods study, where qualitative and quantitative elements were concomitantly implemented and equally prioritized, carried out in three technical colleges linked to a federal public institution in the Brazilian Northeast region. In the qualitative phase, semi-structured interviews were conducted with 24 professors and thematic analysis was applied. In the quantitative study, of the survey type, an instrument was used to screen terms about patient safety with 84 students. The results were combined during the general data interpretation, which was based on the Patient Safety Curricular Guide. Results: two thematic categories emerged: The professors’ understanding about the theme of patient safety in nursing technicians’ training; and Application and projection of the teaching of patient safety in nursing technicians’ training. In the quantitative study, among the 46 screening terms, their identification in the theoretical-practical context predominated in Courses A and C, totaling 36 (78.3%) and 25 (54.3%), respectively. Theoretical teaching stood out in Course B, with 26 terms (56.5%). Conclusion: professional training of Nursing Technician students has a technical focus and does not fully contemplate patient safety issues in the teaching-learning process and, thus, constitutes a challenge for training institutions and professors alike.
