Published: October 2024

This study examines the effects of varying ultraviolet (UV) exposure times on the properties of UDMA/TEG-DMA composite resins, focusing on degree of conversion, surface morphology, water absorption, shrinkage, hardness, and flexural strength. Composite resin samples were exposed to UV light for 30, 60, 90, and 120 min. The degree of conversion was assessed using Fourier Transform Infrared Spectroscopy (FTIR). Surface morphology was analyzed via Scanning Electron Microscopy (SEM). Water absorption and shrinkage were measured following standard procedures, while mechanical properties, including hardness and flexural strength, were evaluated using a Vickers hardness tester and a 3-point bending test, respectively. The results indicate that a UV exposure time of 90 min optimizes the composite resin properties, achieving the highest degree of conversion at 77 %, optimal surface morphology, minimal water absorption and shrinkage, and superior mechanical properties, including maximum flexural strength and hardness. In contrast, both shorter and longer UV exposure times detrimentally affected these properties, with prolonged exposure causing thermal degradation and reduced performance. This research underscores the importance of precise UV curing time control to enhance the performance and durability of UDMA/TEG-DMA composite resins, providing valuable insights and practical guidelines for their application in dental and industrial fields.
HIGHLIGHTS

The incorporation of UDMA/TEG-DMA in composite resin formulations significantly enhanced mechanical properties such as flexural strength and modulus.
Exposure to UV light affected the degree of conversion of the resin, impacting its polymerization kinetics and potentially influencing long-term durability.
The study revealed notable changes in surface morphology, indicating potential implications for bonding characteristics and aesthetic outcomes.
Investigating water absorption and shrinkage behavior provided insights into material stability and dimensional changes over time, critical for clinical longevity and patient satisfaction.

Published: October 2024

Detecting fake accounts is a significant challenge for social media platforms, e-commerce sites, and online services. Malicious users create fake profiles to spread misinformation, commit fraud, or manipulate system behavior. Traditional rule based methods often fail to catch sophisticated fake accounts that resemble genuine user activities. This paper examines the application of Artificial Intelligence (AI) and Machine Learning (ML) techniques to improve the detection of these deceptive accounts. Using KNN model and Gradient Boosting algorithm offer a more robust solution to identifying and combating fake accounts in Social Media Platform.

Authors: Olufeyisola Adesina Opeyemi , Akande Victor Oluwaseun , Adesina Oluwafemi Adewale
Published: October 2024

Background: Quarry workers are exposed to various occupational hazards, including heavy metals, which can impact their health. This study aimed to evaluate selected micronutrients and heavy metals in quarry workers in Ogun State, Nigeria, and assess potential health risks. Materials and Methods: This cross-sectional study was conducted between April and June 2018 at two quarry sites in Ogun State. Blood samples were collected from 60 quarry workers and 30 control subjects. Micronutrients (Copper, Zinc, Iron) and heavy metals (Chromium, Cadmium, Lead, Nickel) were measured using Atomic Absorption Spectrophotometry (AAS). Socio-demographic data and medical history were also recorded. Data were analyzed using SPSS (version 21.0), with t-tests, ANOVA, and Pearson correlation employed to evaluate relationships and group differences. A p-value < 0.05 was considered statistically significant. Results: The mean age of the participants was 30.8 ± 7.4 years, with 88.3% being male. Levels of serum Chromium (p = 0.038) and Cadmium (p = 0.025) were significantly different between quarry workers and controls. Heavy metal levels were also evaluated based on the length of exposure, with significant differences observed for Lead and Nickel. Micronutrient levels, such as Iron and Zinc, showed no significant variation across groups, although differences were noted based on years of work experience.

Published: October 2024

Background: Panretinal photocoagulation (PRP) impacts macular function in eyes with early proliferative diabetic retinopathy (PDR). Herein, we used the multifocal electroretinogram (mfERG) to objectively investigate this concept.
Methods: In this prospective interventional case series, we enrolled patients with treatment-naive early PDR, absence of clinically significant macular edema, and requirement for PRP. All participants underwent detailed ocular examinations. We measured the best-corrected distance visual acuity (BCDVA), conducted optical coherence tomography imaging to measure central macular thickness (CMT), and performed mfERG at baseline and 3 months post-PRP. Amplitude and latency of the mfERG response were evaluated within the innermost four of the five concentric rings.
Results: We enrolled 29 eyes of 23 patients with a mean (standard deviation) age of 54.3 (8.8) years and male-to-female ratio of 1:1.3. The mean BCDVA was unchanged post-treatment (P >0.05), and the BCDVA in 26 eyes (89.7%) was either improved or unchanged, whereas in three eyes (10.3%) it decreased. The mean CMT was unchanged post-PRP (P >0.05). Concerning the mfERG, the mean P1 amplitudes decreased significantly in all four concentric rings from the foveola at 3 months post-PRP compared with baseline values (all P <0.05); however, the latencies were unchanged (all P >0.05). At baseline, BCDVA correlated significantly with both the amplitude (r = + 0.55; P <0.05) and latency (r = - 0.38; P <0.05) of the mfERG in the central ring, whereas a significant correlation was detected with only the amplitude at 3 months post-PRP (r = + 0.52; P <0.05).
Conclusions: Macular function was decreased 3 months post-PRP in patients with early PDR, as indicated by decreased amplitude of the mfERG, whereas the functional and anatomical parameters were stable. The mfERG served as an objective tool for measuring retinal function and predicting visual outcomes post-PRP in eyes with early PDR. A higher amplitude in the mfERG correlated substantially with a better visual outcome post-PRP. Further multi-center longitudinal studies with robust designs including different PDR severity levels may reveal additional objective aftereffects of PRP.
Crocus sativus (saffron) and age-related macular degeneration
Authors: Shamabadi Ahmad , Asadigandomani Hassan , Kazemzadeh Kimia , Farahmand Kimia , Arabzadeh Bahri Razman , Akhondzadeh Shahin
Published: October 2024

Background: Age-related macular degeneration (ARMD) leads to impaired vision and potential blindness. Globally, it accounts for approximately 9% of vision loss cases, and a projected 288 million individuals will be affected by 2040. Current treatments have limitations such as variable effectiveness, high costs, and potential side effects. Additionally, atrophic ARMD management remains challenging. As saffron has shown promising neuroprotective and antioxidant effects by potentially delaying disease progression, this study aims to review the mechanistic, pre-clinical, and clinical evidence of the effects, safety, and tolerability of saffron in ARMD treatment.
Methods: The Scale for the Assessment of Narrative Review Articles was applied in this narrative review. To find relevant literature, the syntax “(saffron OR crocus) AND (retin* OR “geographic atrophy” OR “choroidal neovascular*” OR “macular degeneration”)” was searched in PubMed/MEDLINE. Pre-clinical and clinical original investigations of the effects of saffron in ARMD along with the eligible studies cited in their reference lists were identified and included.
Results: Saffron and its active compounds, crocin and crocetin, have shown promising results in improving visual function and delaying ARMD progression. Several clinical studies have found that daily supplementation with 20–50 mg of saffron or 5–15 mg of crocin for 3–12 months significantly improved best-corrected visual acuity, contrast sensitivity, and retinal function as measured by electroretinogram and microperimetry, with benefits observed in both dry and wet forms of ARMD. The effects were independent of genetic risk factors and maintained during the follow-up periods, suggesting the potential role of saffron as a long-term treatment option. Saffron reduces ARMD progression via anti-angiogenic, neuroprotective, and antioxidant mechanisms. Moreover, saffron is safe and well tolerated.
Conclusions: Although further research is needed to confirm long-term safety and efficacy, current evidence supports the use of saffron or crocin supplements as a safe and tolerable adjunct therapy for ARMD management.

A thought, in itself, very shallow in the face of constant social changes and the yearnings of an increasingly selective market in the art of buying. Strategic preparation is necessary to get out of the cogitation plan and successfully migrate to the real plan. It is necessary to be aware of unexpected facts, of negative-looking impacts, which, if properly used, can be the window of opportunity for the rescue of products seen as secondary as soaps. In times of pandemic, where healthy hygiene habits were emphasized, such as simple hand washing, these products were seen as allies in times of great uncertainty and uncertainty. Thus, for the launch of the moisturizing soap, a theoretical basis was used to support the established marketing actions with a double benefit.

The impact of language variation on educational outcomes in African rural settings
Authors: Igbokwe Innocent Chinonso
Published: October 2024

The present research discusses how language variation may influence educational outcomes within African rural settings concerning indigenous languages, colonial languages, and dialectal diversity. From the critical literature review, it has been determined that mother-tongue education advances academic performance as well as social cohesion and engagement since students find learning more accessible and relevant to their culture. Conversely, the range of dialects, along with other issues such as a lack of resources and proper teacher training, complicates the implementation of mother-tongue education. On the other hand, the use as medium of instruction of a few colonial languages causes inequalities to worsen, alienating rural learners and causing underachievement. This study has strengthened calls for more flexible and localized language policies, with further research on the longer-term impacts of indigenous language education in rural classrooms and the role of dialects. The resolution of at least these linguistic problems would allow the countries of Africa to come closer to equitable and more inclusive education systems.
Keywords: Language Variation, Educational Outcomes, Rural Africa, Indigenous Languages, Colonial Languages, Dialectal Diversity.
Burosumab (Crysvita)
Authors: CDA-AMC
Published: October 2024

Canada’s Drug Agency recommends that Crysvita be reimbursed by public drug plans for the treatment of X-linked hypophosphatemia (XLH) in adult patients if certain conditions are met. The previous recommendation for Crysvita when initiated in pediatric patients who are at least 1 year of age and in whom epiphyseal closure has not yet occurred, continues to apply to those patients.
Crysvita should only be covered to treat patients aged 18 years or older who have a diagnosis of XLH supported by classic clinical features of adult XLH and a confirmed PHEX gene variant, and who have not previously received it. Patients should also have a specific threshold for kidney function or reduced kidney function if it is confirmed not to be due to nephrocalcinosis, bone pain that is caused by XLH or osteomalacia, and have not had a sufficient response to conventional therapy (therapy with active vitamin D and oral phosphate). If a PHEX gene variant is not confirmed, XLH diagnosis can be confirmed with a serum intact fibroblast growth factor 23 (FGF23) level by a Kainos assay.
Crysvita should only be reimbursed if it is prescribed by a physician who works in a comprehensive team of health care providers experienced in the diagnosis and management of XLH and if the cost of Crysvita is reduced. Reimbursement may be renewed on an annual basis for patients who do not meet any of the discontinuation criteria, which are the development of hyperparathyroidism, nephrocalcinosis, fasting hypophosphatemia, or fractures or pseudofractures based on X-ray.
Bile acid malabsorption investigated by selenium-75-homocholic acid taurine (75SeHCAT) scans, a retrospective single-centre experience
Authors: Vulsteke F , De Gersem R , Arts J , Vanuytsel T
Published: October 2024

Background: Bile acid malabsorption (BAM) is a common entity in patients experiencing chronic watery diarrhea. However, literature suggests that BAM is underdiagnosed and undertreated. In many countries 75SeHCAT is the gold standard for diagnosing BAM (1-5). The aim of this retrospective study was to investigate the frequency of BAM using 75SeHCAT scintigraphy and the response to treatment with bile acid sequestrants.

Methods: We retrospectively evaluated the clinical data of 420 patients who had a 75SeHCAT scan from January 2016 to January 2023. Electronic medical records were investigated for risk factors of BAM. BAM was defined as a 75SeHCAT retention of less than 15%. Response to bile acid sequestrants was evaluated based on outpatient clinical reports.

Results: Median age at the time of 75SeHCAT test was 47 years (range 14-87). Out of 420 patients, 192 (46%) had a positive result for BAM. Cholecystectomy and ileal resection were significant predictors for BAM (p<0.001). BAM type 1 is statistically more likely to be more severe compared to type 2 (p<0.0001) and compared to type 3 (p=0.0021). In patients who fulfilled Rome IV criteria for IBS-D or functional diarrhea, 75 out of 121 (38%) tested positive for BAM. Overall, treatment with bile acid binders was effective in 76%.

Conclusions: This retrospective study of patients who underwent SeHCAT scanning confirms that about 1/3 patients presenting with therapy-resistant chronic diarrhea in secondary care suffer from BAM. Including the test in clinical management protocols of chronic diarrhea allows early and quantitative diagnosis and treatment of BAM.

Published: October 2024

Main problem. At the moment, in post-Jungian personality typologies (socionics and MBTI) there are a lot of conflicting hypotheses regarding the intuition / sensory scale.Purpose. Purpose of this article was to testing the content of the Intuition/Sensing scale of Jungian personality types and, namely, the relationship between the Intuition pole and Imagination and Foresight.Methods. For this purpose, we have performed a correlation analysis of typological scales and the scales of the creative thinking model by Williams and the thinking styles model by Epstein.Results and their significance. The results of the analysis demonstrate a statistically significant relationship between the Intuition pole and Imagination. Consequently, it manifests itself in the fact that Intuitive people are more creative than Sensing types people. The Intuition/Sensing scale did not show any correlation with thinking styles by Epstein. According to Epstein, Intuitive thinking style correlateswith the Ethics pole, and Rational thinking style —with the Logic pole. These conclusions are also supported by the relationship between Intuitive thinking style by Epstein and high levels of Emotional Intelligence as measured with the RMET questionnaire. Another important result of this study is the examination of relationship between level of Creativity and Intuitive or Rational thinking styles by Epstein. The results of analysis have shown that high levels of Creativity correlate with high values of both Intuitive and Rational thinking. This suggests that people with a highly developed thinking ability, regardless of its style, are more creative.

Published: October 2024

Este artigo buscou revisar os principais efeitos adversos na saúde bucal de pacientes oncológicos submetidos à quimioterapia e radioterapia, focando em tipos específicos de câncer, como cabeça e pescoço, leucemia e câncer de mama. Apesar de fundamentais para o controle do câncer, esses tratamentos estão associados a complicações bucais severas, como mucosite, xerostomia, infecções orais e osteorradionecrose, que afetam diretamente a qualidade de vida dos pacientes e podem prejudicar a adesão ao tratamento oncológico. A mucosite oral, uma das complicações mais incapacitantes, provoca lesões dolorosas e aumenta o risco de infecções. A xerostomia, causada pela destruição das glândulas salivares, compromete a alimentação e eleva o risco de cáries e doenças periodontais. Pacientes imunossuprimidos são mais vulneráveis a infecções orais, o que aumenta o risco de complicações sistêmicas. A literatura destaca a importância de intervenções preventivas, como laserterapia de baixa intensidade e o uso de saliva artificial, além da presença de dentistas nas equipes multidisciplinares, para melhorar o prognóstico e reduzir essas complicações. A adoção de cuidados odontológicos contínuos desde o início do tratamento oncológico é essencial para garantir melhores resultados clínico.

Exploring Atmospheric Nitrate Formation Mechanisms during the Winters of 2013 and 2018 in the North China Region via Modeling and Isotopic Analysis
Authors: Liu Zhenze , Qi Jianhua , Ni Yuanzhe , Xue Likun , Liu Xiaohuan
Published: October 2024

Abstract. Nitrate (NO3-) has surpassed sulfate as the dominant secondary inorganic ion, posing a significant challenge to air quality improvement in China. We utilized the WRF-CMAQ model and isotopic analysis to investigate nitrate formation mechanisms in inland and coastal cities in North China during the winters of 2013 and 2018. Among the seven nitrate formation pathways, the oxidation reaction of OH radicals with NO2 (OH + NO2) and the heterogeneous reaction of N2O5 (hetN2O5) were dominant pathways (88 %–95.5 % NO3-), while others contributed less than 12.4 %. In inland cities, 63.7 %–85.6 % of nitrate formed via OH + NO2, and 8.3 %–27.7 % from hetN2O5. In coastal cities, about half of nitrate (48.2 %–56.5 %) was produced from OH + NO2, while hetN2O5 contributed 37.0 %–45.7 % due to higher N2O5 concentrations and longer NO3 radical lifetimes. Compared with 2013, the OH + NO2 contribution in 2018 increased by 7.6 % in inland cities and 3.6 % in coastal cities, driven by greater atmospheric oxidizing capacity. Scenario simulations showed that a 60 % reduction in NOx emissions could lower nitrate levels by 38.4 %, while combined reductions in NH3, NOx, and VOCs led to a 59.8 % decrease, from 14.6 μg/m3 to 5.9 μg/m3. These results highlight the need for comprehensive strategies targeting NH3, NOx, and VOCs to reduce nitrate pollution.
A three-stage model pipeline predicting regional avalanche danger in Switzerland (RAvaFcast v1.0.0): a decision-support tool for operational avalanche forecasting
Authors: Maissen Alessandro , Techel Frank , Volpi Michele
Published: October 2024

Abstract. Despite the increasing use of physical snow cover simulations in regional avalanche forecasting, avalanche forecasting is still an expert-based decision-making process. However, recently, it has become possible to obtain fully automated avalanche danger level predictions with satisfying accuracy by combining physically based snow cover models with machine learning approaches. These predictions are made at the location of automated weather stations close to avalanche starting zones. To bridge the gap between these local predictions and fully data- and model-driven regional avalanche danger maps, we developed and evaluated a three-stage model pipeline (RAvaFcast v1.0.0), involving the steps classification, interpolation, and aggregation. More specifically, we evaluated the impact of various terrain features on the performance of a Gaussian-process-based model for interpolation of local predictions to unobserved locations on a dense grid. Aggregating these predictions using an elevation-based strategy, we estimated the regional danger level and the corresponding elevation range for predefined warning regions, resulting in a forecast similar to the human-made public avalanche forecast in Switzerland. The best-performing model matched the human-made forecasts with a mean day accuracy of approximately 66 % for the entire forecast domain and 70 % specifically for the Alps. However, the performance depended strongly on the classifier's accuracy (i.e., a mean day accuracy of 68 %) and the density of local predictions available for the interpolation task. Despite these limitations, we believe that the proposed three-stage model pipeline has the potential to improve the interpretability of machine-made danger level predictions and has, thus, the potential to assist avalanche forecasters during forecast preparation, for instance, by being integrated in the forecast process in the form of an independent virtual forecaster.

This study investigates the causes of deforestation using panel data for top deforested countries from 1995 to 2022. We apply Panel Corrected Standard Error (PCSE) technique. The findings affirm that urbanization and water stress has negative and significant effect on deforestation and unemployment and agricultural exports have positive and significant effect on deforestation. The results of this study serve as the basis for the recommendations presented in the present research strategy such as labour opportunity cost might be increased to reduce agricultural rent. Stabilization and regeneration of the forest cover should be prompted by a greater demand for and a restricted supply of forest products.

Published: October 2024

The current study empirically probes into the role of economic complexity and green technologies on environmental degradation under STIRPAT framework in world’s top polluting countries over 2000 to 2020 period. To empirically analyze the relationships, Common Correlated Effects Mean Group (CCEMG) estimation technique is used because of the existence of the cross sectional dependence issue in panel data. The findings reveal that economic complexity increases but green technologies decrease CO2 emissions in studied economies. By providing the comprehensive understanding on the relationship between green technologies, economic complexity and CO2 emissions, the present study recommends the governments of the concerned countries to implement relevant policies and practices for improving the production structure and foster the research and development activities to promote the development and use of green technologies to curb CO2 emissions in studied economies.

Mục tiêu: Phân tích một số yếu tố ảnh hưởng đến việc tuân thủ quy trình xử lý trang thiết bị y tế của nhân viên y tế tại Bệnh viện Đa khoa Sài Gòn - Hà Tĩnh năm 2024.
Đối tượng và phương pháp nghiên cứu: Khảo sát cắt ngang kết hợp nghiên cứu định tính thông qua phỏng vấn sâu đại diện lãnh đạo (phó giám đốc và giám đốc điều hành bệnh viện), cán bộ kiểm soát nhiễm khuẩn (2 người) và nhân viên y tế trực tiếp xử lý trang thiết bị y tế (10 người).
Kết quả: Có quy trình hướng dẫn đầy đủ, chi tiết và phù hợp; có quy định về khen thưởng, xử phạt và chế độ độc hại đối với nhân viên y tế khi xử lý trang thiết bị; có cơ sở vật chất, trang thiết bị đầy đủ, hiện đại để kiểm soát nhiễm khuẩn, nâng cao tính tuân thủ trong xử lý trang thiết bị y tế. Tại Bệnh viện Đa khoa Sài Gòn - Hà Tĩnh, chưa có chế độ khen thưởng, xử phạt đối với hoạt động xử lý trang thiết bị y tế, thiếu khu vực chuyên trách xử lý trang thiết bị y tế, phòng rửa dụng cụ còn nóng bức, ngột ngạt; số lượng nhân viên y tế trong mạng lưới kiểm soát nhiễm khuẩn còn ít, đội ngũ nhân viên chuyên môn được đào tạo bài bản nhưng đội ngũ nhân viên y tế bán thời gian trong mạng lưới chưa được đào tạo bài bản. Một số nhân viên y tế chưa nhận thức được tầm quan trọng của việc xử lý trang thiết bị y tế. Dụng cụ càng đơn giản hoặc quy trình xử lý càng đơn giản, càng ít chi tiết thì càng dễ gia công theo quy trình kỹ thuật.
Kết luận: Bệnh viện cần khắc phục những hạn chế và phát huy những yếu tố tích cực để nâng cao năng lực của nhân viên y tế trong việc tuân thủ xử lý trang thiết bị y tế.

ANALYSIS OF THE PERCEPTION OF BODY IMAGE IN FIT KID ATHLETES
Authors: Selva Lucía , Ávalos-Ramos María Alejandra
Published: October 2024

The aim of this research was to analyze the degree of dissatisfaction with body image—defined as the dissatisfaction resulting from the difference between the desired silhouette and the perceived one—among Fit Kid athletes. The study compared data based on age ranges and levels of competition and examined the possible association between higher weight and BMI with increased concern for body image. The Body Shape Questionnaire (BSQ) was used, and data were analyzed using the SPSS 28.0 statistical package. The main findings reveal a higher degree of body image dissatisfaction at the highest level of competition (national level) and among athletes with higher BMI and weight. Specifically, the factor with the highest scores was body dissatisfaction with the lower body. This suggests a higher risk of body image issues in late adolescence and at higher competitive levels, as well as among athletes with higher BMI values. These findings could offer valuable insights for coaches, who might address these issues through collaboration with nutritionists and sports psychologists.

Rhythmic gymnastics is characterized by high mobility demands on the spine, which can lead to structural changes and associated injuries or pain. The aim of this study is to assess and compare spinal posture in different positions, mobility, and pain perception among RG athletes. The sample consisted of 34 gymnasts (age: 14.18 ± 2.17) of grassroots and federation levels. Spinal posture and mobility were analyzed using the Spinal Mouse® system, along with pain perception (location and intensity) and body composition. Most gymnasts exhibited normal spinal curvature in both standing and sitting positions. Significant differences (p<0.05) were only found in the sacral curve during extension. Regarding lumbar mobility, differences in sacral mobility from standing to extension were noted, with the federation-level gymnasts showing a greater tendency for hyperlordosis in extension. In terms of pain, the lumbar region was the most affected, with 32.4% of cases reporting pain. It was observed that gymnasts experiencing pain displayed more pronounced lumbar hyperlordosis in the standing position. A low but significant correlation was found between lumbar pain and its intensity (p=0.045), and a moderate correlation was observed between hip pain and pelvic tilt. The gymnasts demonstrated a greater tendency for lumbar hyperlordosis in the standing position and during the transition from standing to extension, which was more pronounced among federation-level gymnasts. Furthermore, there appears to be a stronger correlation between hyperlordosis and the occurrence of lumbar pain, as well as the intensity of pain.
JUMP PERFORMANCE IN TRAMPOLINE ATHLETES AND HOW TO MEASURE IT: DEVELOPING A REPEATED JUMP TEST

A competitive trampoline routine consists of ten scored jumps on which trampoline gymnasts need to exhibit an adequate strength endurance performance of their lower extremities. These strength endurance requirements are assessed with “Repeated Jump Tests” (RJT). However, existing tests are not designed for trampolining, but rather for game sports. Such tests aim, for example, at different number of repetitions and for minimizing ground contact time, thus lacking the specific repetitions and intensity of a trampoline routine. Therefore, the aim of this study is to develop a RJT specifically for trampolining that will assess jump height, performance decrement (PD) during RJT, and jump-to-jump fluctuations. Twenty-nine elite trampoline gymnasts (TR) from the junior national squad (JNS-TR; n = 21) and the senior national squad (SNS-TR; n = 8), 21 athletes from jump-intensive game sports (GS; comprising volleyball n = 15; handball n = 6), and 16 PE students (PE) completed the RJT consisting of twelve repeated jumps. Group differences were analyzed by ANOVA and trampoline squad differences via t-tests. Results showed that TR had a lower PD compared to GS and PE (p < .05). SNS-TR trampoline gymnasts show lower jump-to-jump fluctuations than JNS-TR trampoline gymnasts (p < .05). TR exhibited a superior performance in the RJT regarding PD compared to GS and PE. In conclusion, our RJT is proposed as a new tool for validly measuring repeated jump performance in trampoline gymnasts.
