Item Current status of sport performance in Boccia: systematic review of the literature.(Retos, 2023) Ferreira, Cátia C.; Gamonales, José M; Espada, Mário C.; Muñoz-Jiménez, JesúsLa Boccia es un deporte Paralímpico y practicado con una perspectiva recreativa por parte de la población. El rendimiento deportivo en este deporte Paralímpico implica complejidad. Por ello, el objetivo de este estudio fue realizar una revisión sistemática de la literatura relacionada con la Boccia, y específicamente en el área del rendimiento deportivo. Las palabras clave “Boccia” y “Performance” se utilizaron como descriptores en la búsqueda de referencias. Las palabras en inglés fueron introducidas en las bases de datos Web of Science, PubMed, Scopus and Google Scholar. Se encontraron 669 documentos usando la palabra “Boccia”, y después de incluir la palabra “Performance” los resultados fueron reducidos a 26 documentos. Para ello, se aplicaron tres criterios de exclusión: i) Documentos no publicados en revistas científicas; ii) Documentos no mencionan en el título o resumen tanto “Boccia” como “Performance”; y iii) Los documentos de Tesis Doctorales, Capítulos de libros, Resúmenes de conferencias o Resumen. Finalmente, se seleccionaron 9 documentos que cumplían con los criterios de inclusión y exclusión hasta Febrero del 2022. Los resultados confirmaron que los documentos relacionados con la Boccia son escasos en comparación con otros deportes para personas con discapacidad. Por tanto, el deporte Paralímpico ha sido analizado desde la perspectiva de una gran diversidad de disciplinas, sin embargo, dentro de la disciplina “Coaching Science” existe un gran espacio y necesidad de aumentar las investigaciones, con la finalidad de mejorar las condiciones de entrenamiento y optimizar el rendimiento deportivo.Item Documents Publication Evolution (1990–2022) Related to Physical Activity and Healthy Habits, a Bibliometric Review.(Healthcare, 2023) Hernández-Beltrán, Víctor; Espada, Mário C.; Santos, Fernando J.; Ferreira, Cátia C.; Gamonales, José M.This research aims to provide an overview of the growing number of scientific literature publications related to Physical Activity and Healthy Habits. A bibliometric analysis between 1990 and 2022 in the Web of Science was carried out, following the bibliometric analysis law, using Microsoft Excel and VosViewer Software for analysis and data processing. A total of 276 documents (262 primary studies and 14 revisions) related to the topic under study were located. The results reveal an exponential growth of scientific production by 48% between 2006 and 2022. Public Environmental Occupational Health, Kaprio, J., and the USA were the knowledge field, author, and country most productive, respectively. A great thematic diversity was found related to the most used keywords by the authors, such as “physical activity”, “health habits”, “exercise”, and “obesity”. Thus, the research related to this theme is really in an exponential phase, with great interest in the importance of physical activity and healthy habits, implying practical decisions in policies to develop programs to promote physical activity and healthy habits.Item Evolution of Documents Related to Biomechanics Research in Gymnastics.(Biomechanics, 2023) Hernández-Beltrán, Víctor; Espada, Mário C.; Muñoz-Jiménez, Jesús; León, Kiko; Ferreira, Cátia C.; Parraca, Jose A; Gamonales, José MBiomechanical analysis has been one of the most used procedures when aiming to improve performance in sports and is also very relevant and decisive in the final classification of competitive events in sports such as gymnastics. Hence, this study sought to provide an overview of the number of scientific literature publications related to biomechanics research in gymnastics. The document search was completed in March 2023 and reflected a bibliometric analysis considering the published manuscripts up to 31 December 2022. Data collection was performed on the Web of Science, following the bibliometric analysis law, using Microsoft Excel and VosViewer Software (v1.6.19) for analysis and data processing. A total of 325 documents related to the topic under study were located. The results highlight that the older manuscripts date from 1980, with a growing trend of publications from that moment until now and a very visible increase in 2015, and that Sport Science is the category associated with more published manuscripts. A total of 30 manuscripts have 30 or more citations, 746 authors and co-authors are associated with the publications, and 58 co-authorships have published one or more studies. Moreover, 47 countries or regions have been associated with the topic under study, with the USA, England, and Australia being the countries with the most published articles and citations. The study also found that the highest frequency keywords are: “gymnastics” (n = 122), “biomechanics” (n = 73), “simulation” (n = 27), and “performance” (n = 25), considering the average year of publication of the documents, “balance” (n = 11), “artistic gymnastic” (n = 14) and “training” (n = 25) are the most frequently used terms. This study reveals that the topic of biomechanics in gymnastics has shown sustained growth and deserves the attention of the scientific community, but at the same time, there is still much room for research development.Item Lower Limb Unilateral and Bilateral Strength Asymmetry in High-Level Male Senior and Professional Football Players.(Healthcare, 2023) Espada, Mário C.; Jardim, Marco; Assunção, Rafael; Estaca, Alexandre; Ferreira, Cátia C.; Pessôa Filho, Dalton M.; Verardi, Carlos E. L.; Gamonales, José M.; Santos, Fernando J.This study sought to assess the relationship between different jumping asymmetries and associated performance variables in high-level male senior and professional football players. Nineteen football players with at least 12 years of training experience (23.2 ± 3.1 years of age; 75.2 ± 4.8 kg of body mass and 181 ± 0.06 cm of height) participated in this study performing countermovement jump (CMJ), squat jump (SJ), single-leg CMJ and drop jump (DJ), associated performance variable eccentric utilization ratio (EUR), stretch-shortening cycle (SSC), bilateral deficit (BLD), and limb symmetry index (LSI) were determined. High correlations were observed between different methodologies of jump tests and associated performance indicators (SSC, BLD, EUR), except LSI. Moreover, CMJ and SJ results were different (p < 0.05), but no differences were found between interlimb in CMJ (p = 0.19) and DJ (p = 0.14). Between the same limbs and different jumps differences were detected in CMJ and DJ (p < 0.01), and it has also been found that the laterality effect size on strength was small in CMJ (ES = 0.30) and DJ (ES = 0.35). LSI between CMJ and DJ was not different despite higher mean values in CMJ, and although mean BLD was positive (>100%), the results highlight the need for individual evaluation since eight players scored negatively. An in-depth and accurate analysis of performance in preseason screening jump tests should be considered, aiming to detect injury risk, specifically evaluating different jumping test methodologies, and determining jumping associated performance variables for each test, namely EUR, SSC, BLD, and LSI. Specific muscle-strengthening exercises could be implemented based on this study results and outcomes, aiming to reduce injury risks and lower extremity asymmetries and to enhance individual football performance in high-level male senior and professional football players. Sports institutions should pay special attention regarding potential health problems in athletes exposed to daily high training loads.Item Research Trends in the Effect of Caffeine Intake on Fat Oxidation: A Bibliometric and Visual Analysis.(Nutrients, 2023) Gutiérrez Hellín, Jorge; Del Coso, Juan; Espada, Mário C.; Hernández-Beltrán, Víctor; Ferreira, Cátia C.; Varillas Delgado, David; Mendoza Laiz, Nuria; Roberts, Justin D.; Gamonales, José MIn the last few decades, numerous studies pertaining to research groups worldwide have investigated the effects of oral caffeine intake on fat oxidation at rest, during exercise, and after exercise. However, there is no bibliometric analysis to assess the large volume of scientific output associated with this topic. A bibliometric analysis of this topic may be used by researchers to assess the current scientific interest in the application of caffeine as a nutritional strategy to augment fat oxidation, the journals with more interest in this type of publication, and to draw international collaborations between groups working in the same area. For these reasons, the purpose of this study was to assess the research activity regarding oral caffeine intake and fat oxidation rate in the last few decades by conducting a bibliometric and visual analysis. Relevant publications from 1992 to 2022 were retrieved from the Web of Science (WoS) Core Collection database. Quantitative and qualitative variables were collected, including the number of publications and citations, H-indexes, journals of citation reports, co-authorship, co-citation, and the co-occurrence of keywords. There were 182 total publications, while the number of annual publications is saw-shaped with a modest increase of 11.3% from 2000 to 2009 to 2010 to 2019. The United States was the country with the highest number of publications (24.17% of the total number of articles), followed by the Netherlands (17.03%). According to citation analyses, the average number of citations per document is 130, although there are 21 documents that have received more than 100 citations; the most cited document reached 644 citations. These citation data support the overall relevance of this topic in the fields of nutrition and dietetics and sport sciences that when combined harbored 85.71% of all articles published in the WoS. The most productive author was Westerterp-Plantenga with 16 articles (8.79% of the total number of articles). Nutrients was the journal that published the largest number of articles on this topic (6.59% of the total number of articles). Last, there is a tendency to include keywords such as “performance”, “carbohydrate”, and “ergogenic aid” in the newer articles, while “obesity”, “thermogenic”, and “tea” are the keywords more commonly included in older documents. Although research into the role of caffeine on fat oxidation has existed since the 1970s, our analysis suggests that the scientific output associated with this topic has progressively increased since 1992, demonstrating that this is a nutritional research area with a strong foundational base of scientific evidence. Based on the findings of this bibliometric analysis, future investigation may consider focusing on the effects of sex and tolerance to caffeine to widen the assessment of the effectiveness of oral caffeine intake as a nutritional strategy to augment the use of fat as a fuel, as these terms rarely appear in the studies included in this analysis. Additionally, more translational research is necessary as the studies that investigate the effect of oral caffeine intake in ecologically valid contexts (i.e., exercise training programs for individuals with excessive adiposity) are only a minor part of the studies on this topic.Item The effect of pitch size manipulation during small sided-games performed by different age category football players: a pilot study.(Journal of Men's Health, 2023) Espada, Mário C.; Gamonales, José M.; Verardi, Carlos E.L.; Pessôa Filho, Dalton M.; Ferreira, Cátia C.; Robalo, Ricardo A.M.; Dias, Amândio A.P.; Hernández-Beltrán, Víctor; Santos, Fernando J.This research aimed to analyse the pitch size manipulation effect on internal and external load and to study the age effect on the studied variables in different smallsided games (SSGs) formats. Male U-12 (n = 8), U-15 (n = 8) youth football players, and U-23 (n = 8) professional cohorts participated in the study. Two SSGs formats were analyzed, goalkeeper (GK) + 4 vs. 4 + GK, 3 minutes play in 20×30 m and 24 × 36 m, with 3 minutes rest between bouts. The variance analysis Anova two-way was used to analyse two independent factors, pitch size, and age group. The playing area manipulation had an effect under the following variables: distance (p<0.001), speed 0–6 km/h (p < 0.001), speed 12–18 km/h (p < 0.001), speed 18–21 km/h (p < 0.001), accelerations (Ac.) 1–2 m/s2 (p < 0.001), decelerations (Dc.) 2–3 m/s2 (p < 0.001), metabolic power (Pmet) (p < 0.001) and high metabolic load distance (HMLD) (p < 0.001). The age group influenced the distance covered (p < 0.001), speed 0–6 km/h (p < 0.001), speed 6–12 km/h (p < 0.001), speed 12–18 km/h (p < 0.001), speed 21–24 km/h (p = 0.030), Ac. 1–2 m/s2 (p < 0.001), Ac. 1–2 m/s2 (p < 0.001Pmet (p < 0.001), HMLD (p < 0.001) and training impulse (TRIMP) (p < 0.001). Playing area manipulation in football SSGs promotes an increase in external load intensity, namely, larger areas are suitable for larger effects at high speeds (>21 km/h) and TRIMP. A careful and detailed evaluation of training tasks, considering the different age category football players, is important to optimize the planning in football, aiming at improving players’ condition and performance and avoiding health problems and injuries
