- Characterizing psychomotor abilities of male handball players of different age categoriesPublication . Martins, Francisco; Śliż, Maciej; França, Cíntia; Sarmento, Hugo; Gouveia, Élvio Rubio; Campos, Pedro; Lopes, Helder; Przednowek, Krzysztof; Pestana Martins, João Francisco; França, Cíntia; Borges Sarmento, Hugo Miguel; Sarmento, Hugo; Gouveia, Elvio Rúbio; Gouveia, Élvio Rúbio; Pereira Campos, Pedro Filipe; Lopes, Helder; Przednowek, KrzysztofSports performance is highly influenced by players’ mental, emotional, and psychomotor abilities. Particularly in handball, training methods aim to maximize players’ performance by fusing physical conditioning with cognitive abilities. The aim of this research was twofold: (1) to characterize players’ psychomotor abilities according to their age categories (U14, U16, and U18), and (2) to analyze the differences between psychomotor abilities profiles according to players’ field positions. The study population comprised 75 male youth handball players (15.3 ± 1.5 years) from different competitive age groups (U14 = 20 players; U16 = 27 players; U18 = 28 players). The psychomotor abilities were evaluated using the Test2Drive system. Three tests were performed to measure psychomotor abilities: (a) a simple reaction time test (SIRT), (b) a choice reaction time test (CHORT), and (c) a spatial anticipation test (SPANT). The only statistically significant difference was observed in the percentage of correct answers in the SPANT, showing that U16 players had a higher rate of correct answers than the others. However, some trends were visible throughout the analysis: (i) the U16 group performed better in terms of reaction time in all the tests, (ii) right-wingers were always the ones who had the best percentage of correct answers, and (iii) central players had the best movement time performance. Future research should include youth players' maturation stage, body composition, and physical fitness performance to characterize their profile deeply and analyze their psychomotor abilities, considering other factors that can impact their sports performance.

- Lower body strength and body composition in female footballPublication . França, Cíntia; Saldanha, Carolina; Martins, Francisco; Nascimento, Marcelo de Maio; Marques, Adilson; Ihle, Andreas; Sarmento, Hugo; Campos, Pedro; Gouveia, Élvio Rubio; França, Cíntia; da Costa Saldanha, Carolina Filipa; Pestana Martins, João Francisco; Marques, Adilson; Ihle, Andreas; Sarmento, Hugo; Pereira Campos, Pedro Filipe; Gouveia, Élvio RúbioAbstract Lower-body strength plays a crucial role in football performance and injury prevention, and thus, monitoring of strength variables has become crucial in the training process. This study aims to (1) assess knee muscle strength performance through intra- and inter-limb asymmetries and (2) examine the relationships between knee muscle strength, body composition, and vertical jump performance (squat jump and countermovement jump). Twenty-seven semiprofessional female football players (21.5 ± 4.9 years) were evaluated for body composition, isokinetic knee muscle strength (60º/s and 180º/s), and vertical jump tasks. Peak torque (PT), peak torque/body weight (PT/BW), bilateral strength deficit, and the hamstring-to-quadriceps strength ratio (H/Q) for knee extensors (KE) and flexors (KF) in both the preferred and non-preferred legs. The H/Q ratio and the bilateral strength deficit revealed no significant intra- or inter-limb asymmetries in knee muscle strength. Strong correlations were found between vertical jump performance and KE strength at both 60º/s (p ≤ 0.01) and 180º/s (p ≤ 0.01). Additionally, a significant negative correlation was observed between vertical jump performance and body fat percentage (p ≤ 0.01). These findings highlight the critical role of knee muscle strength in explosive tasks and underline the negative impact of higher body fat on lower-body strength performance.
- MALDI-TOF MS: a promising analytical approach to cancer diagnostics and monitoringPublication . Sousa, Patrícia; Silva, Laurentina; Luís, Catarina; Câmara, José S.; Perestrelo, Rosa; Sousa Luís, Catarina Grace; Câmara, José; Perestrelo, RosaCancer remains the second most common cause of death after cardiovascular diseases, accounting for nearly 10 million deaths in 2020. Although the incidence of cancer increases considerably with age, the cancer burden can also be reduced and have a high chance of cure through early detection, appropriate treatment, and care of patients. The development of high-throughput analytical approaches, like matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), contributes to identifying a pool of proteins/peptides as putative biomarkers for the early detection, diagnosis, and tumor progression. The purpose of the current review is to present an updated outline of recent proteome/peptidome research to establish putative cancer biomarkers using MALDI-TOF MS and highlight the applicability of statistical analysis in the oncology field. The pros and cons of MALDI-TOF MS application on cancer diagnostics and monitoring will be discussed, as well as compared with tandem mass spectrometry (MS/MS)-based proteomics (e.g., liquid chromatography–tandem mass spectrometry). In addition, pre-analytical (e.g., sample quality control) and analytical (e.g., sample pre-treatment, instrumental analytical conditions) properties that influence the robustness of MALDI-TOF MS data will be also discussed.
- Postural stability of polish special forces operatorsPublication . Dziadek, Bartosz; Paśko, Wojciech; Podgórski, Rafał; Śliż, Maciej; Krawczyk, Grzegorz; Brożyna, Maciej; Marszałek, Patryk; Iskra, Janusz; Maciejewski, Konrad; Gouveia, Élvio Rúbio; França, Cíntia; Przednowek, Krzysztof; Gouveia, Élvio Rúbio; França, CíntiaThe level of balance can play an essential role in a soldier’s performance. For a Special Forces soldier, the footwear used or extra weight may be important factors affecting their balance level during combat operations or trainings. Therefore, the purpose of the study was to assess the level of static balance of Special Forces Operators and to determine the influence of select elements of a soldier’s combat uniform and equipment on balance levels. The study group consisted of 37 Polish Special Forces Operators. To assess the level of static balance, the Romberg test was used in three variants (barefoot, with shoes, and with shoes, helmet, and vest). The measurements were made using the AMTI AccuGait portable force platform. The results of the analysis showed that the calculated average values of selected static balance parameters of soldiers differed depending on the variant of the Romberg test used, and in most cases, those differences were statistically significant ( α<0. ). The lowest average values of parameters characterizing the level of static balance of Special Forces soldiers were calculated for barefoot measurements. The measurements with shoes and additional loads showed a statistically significant increase in almost all analysed parameters compared to barefoot measurements.
- Prevalence of autism spectrum disorder in children in the Azores Islands (Portugal): sociodemographic and clinical profilePublication . Conde, Ana Rita; Mota, Pilar; Botelho, Tânia; Caldeira, Suzana; Rego, Isabel; Silva, Osvaldo; Sousa, Áurea Sandra Toledo de; Freitas, Carina; De Barros Freitas, Carina Patrícia; Freitas, CarinaAbstract Prevalence studies are essential to provide objective indicators about Autism Spectrum Disorder (ASD) and are a source of information for public policies. This study aimed to estimate the prevalence of ASD among children in the Azores Islands (Portugal). Administrative data on the number of children with a proven diagnosis of ASD were collected from all schools. Parents completed a questionnaire about the child’s sociodemographic characteristics, the diagnostic process, and clinical history. The overall prevalence of ASD in the Azores region was 9.92 per 1000 children, approximately equivalent to 1% (0.99). The prevalence of ASD in the Azores seems to be higher when compared with the global rate in Portugal, as well as with other regions of Europe. There appears to be a concentration of children with ASD in the region, and the results appear to support the hypothesis of a heritable predisposition to ASD.
- Psychomotor abilities, body composition and training experience of elite and sub-elite handball playersPublication . Śliż, Maciej; França, Cíntia; Martins, Francisco; Marszałek, Patryk; Gouveia, Élvio Rubio; Przednowek, Krzysztof; França, Cíntia; Pestana Martins, João Francisco; Gouveia, Élvio RúbioBackground: Handball is characterized by fast and dynamic movements requiring appropriate psychomotor abilities and body mass composition. High levels of reaction and movement time can be crucial factors influencing quick reactions and in-time decision-making at the handball court. The aim of this study was to assess psychomotor abilities among elite and sub-elite Polish and Portuguese male and female handball players at the different levels of competition. Methods: Computer Test2Drive systems were used to assess reaction time, movement time and percentage of correct responses of 199 handball players (60 females). Results: Statistically significant correlation was noted between SIRT cr and the Elite group (r = 0.44) and between the CHORT cr and all groups (r = 0.33). A statistical correlation between CHORT MT and total body water (r = 0.44) was also noted in Elite handball players. Conclusions: High level of psychomotor abilities and body composition seems to have impact on the competitive level in male and female handball players.
- Understanding the tolerance of different strains of human pathogenic bacteria to acidic environmentsPublication . Figueira, Priscilla Porto; Câmara, José S.; Vigário, Ana M.; Pereira, Jorge A. M.; Porto-Figueira, Priscilla; Câmara, José; Augusto Machado Pereira, JorgeIt is known that many bacteria are susceptible to low pH, but it is less clear how the acid nature influences this susceptibility. The objective of this work was to evaluate the susceptibility of selected bacteria to different low pH conditions and to understand if their tolerance is affected by the type of acid (organic vs inorganic) in the media acidification. Strains of different species of human pathogenic bacteria were cultivated at different acidic conditions, using organic or inorganic acids. Overall, we verified that tolerance to acidic conditions is dependent on the type of acid used to acidify the growing medium, organic or inorganic. The strains analysed, although having different tolerance to low pH, were shown to be more susceptible to organic than inorganic acids. This result shows that beyond the pH of the media, the nature of the acid affects bacterial growth. Such a result has consequences in the evaluation of the efficiency of an antibacterial extract, which should take into consideration the differential susceptibility of bacteria to low pHs obtained using organic or inorganic acids.
