- Assessment of body composition, lower limbs power, and anaerobic power of senior soccer players in Portugal : differences according to the competitive levelPublication . Tereso, Diogo; Paulo, Rui; Petrica, João; Duarte-Mendes, Pedro; Gamonales, José M.; Ibañez, Sergio J.Background. During a soccer game, the most diversified stimuli occur all the time, the physical condition level plays a determinant role, and there may be variations according to the competitive level. In this sense, the present study aimed to verify differences in body composition, lower limbs power, and anaerobic power, comparing senior soccer players of different competitive levels. Methods. Participants were 81 players belonging to six soccer teams, aged between 18 and 35 years, with a mean age of 23.14 ± 4.23 years, who were divided into three distinct competitive levels: Elite, Sub-Elite and Non-Elite. The players performed bioimpedance evaluations on a tetrapolarInbody270 scale (body composition), the Countermovement Jump (CMJ) through the ChronoJump (lower limbs power), and Running Anaerobic Sprint Test (RAST) (anaerobic power). Results. Based on the competitive level analysis, we verified that the players present body composition values similar to each other regardless of the competitive level in which they play. Concerning the performance evaluations, we verified that the elite players present higher values of highest jump (p = 0.012; d = 0.76, moderate; and p = 0.022; d = 0.71, moderate) and maximum force produced (p = 0.05; d = 0.64, moderate; and p = 0.002; d = 1.00, moderate), together with higher values of anaerobic power (p < 0.001; d = 2.43, very large; and p < 0.001; d = 2.22, very large), compared to the others. Conclusions. We can thus conclude that there is a homogeneity regarding the body composition of soccer players, regardless of their competitive level; in turn, elite players show better performance indicators in all variables.

- Avaliação da composição corporal, da potência de membros inferiores e da potência anaeróbia de jogadores de futebol: diferenças consoante a posição em campoPublication . Tereso, Diogo; Gamonales, José M.; Petrica, João; Ibañez, Sergio J.; Paulo, RuiO objetivo do estudo foi avaliar a composição corporal, a potência de membros inferiores e a potência anaeróbia, comparando as posições em campo de jogadores de futebol. Participaram 81 jogadores de futebol e foram realizadas avaliações de bioimpedância, Countermovement Jump e Running Anaerobic Sprint Test. Verificou-se que existem diferenças na composição corporal, apresentando os guarda-redes e os defesas centrais os valores mais elevados. Relativamente à variável altura, as principais diferenças ocorrem quando comparamos os alas (p< 0.001) com as restantes posições e os defesas centrais em comparação com os médios centros (p= 0.002), e avançados (p= 0.010). Também os alas em relação à maioria das outras posições, na variável massa corporal (p≤ 0.010), massa muscular (p≤ 0.033), massa livre de gordura (p≤ 0.024) e massa gorda (p≤ 0.045). Na avaliação da potência de membros inferiores, verificaram se diferenças entre os guarda-redes e avançados, na variável maior salto (p= 0.021), por sua vez, foram encontradas diferenças quando comparamos os guarda-redes com os alas, médios centro e avançados (p≤ 0.028) e entre os defesas centrais com os alas, na força máxima produzida (p= 0.002). Nas avaliações de potência anaeróbia, não se verificaram diferenças. Pode-se assim concluir que existem características específicas de composição corporal entre as posições de jogadores de futebol. As posições que envolvem movimentos explosivos e um maior número de ações aéreas, apresentam melhores desempenhos nestas avaliações como se verificou. Por fim, nas avaliações de potência anaeróbia, esta homogeneidade poderá ser explicada pelas exigências comuns que o futebol moderno apresenta.

- Study of body composition and motor skills of futsal athletes of different competitive levelsPublication . Belo, João; Santos, João Valente dos; Pereira, João R.; Duarte-Mendes, Pedro; Gamonales, José M.; Paulo, RuiThis study aimed to verify whether there are differences in the body composition, functionality, lower-limb power, agility, and cardiorespiratory capacity in futsal players, comparing futsal athletes by competitive level. The athletes (N = 84) were divided into three groups: group Elite (N = 29), group Sub-Elite (N = 29), and group Non-Elite (N = 26). Anthropometric variables were analyzed through a bioimpedance scale (Inbody 270), and functionality was analyzed through a functional movement screen battery. The power of the lower limbs was tested with the Abalakov jump, the agility with the zigzag agility test, and the cardiorespiratory capacity through the futsal intermittent endurance test. Anthropometric data from futsal athletes revealed a homogeneity in relation to the variables analyzed, regardless of the level of competition in which they operate. In performance variables, the power of the members and functionality was considered a discriminating factor of the level of competitiveness of the athletes, with the Elite group athletes presenting the best values. We concluded that there were no differences in relation to the body composition of the athletes. However, the athletes of higher levels, as a rule, present better performances in physiological aspects, results that can be explained by the fact that there is a better periodization in terms of training, with more intense loads and more complex competitive calendars, thus resulting in a greater specialization of these athletes.
- Analysis of sports injuries in academy integrated u-16 and u-18 football players Análisis de las lesiones deportivas en jugadores de fútbol sub-16 y sub-18 integrados en academiaPublication . Gamonales, José M.; Hernández-Beltrán, Victor; Barguerias-Martínez, Jesús; Gómez-Carrero, Sergio; Ferreira, Cátia; Paulo, Rui; Espada, Mário C.The problematic of analysis and the possible causes of injuries in football continues to be a topic of extreme relevance. In this sense, the aim of this study was to analyze the injuries of U-16 and U-18 soccer players, according to the category and game position. In this ex post facto study (Quasi-experimental methodology) 111 players participated, belonging to the U-16A (n=25), U16B (n=24), U-18A (n=20), U-18B (n=22), and U-18C (n=20), youth teams of a professional soccer team in the First Division of the Spanish Soccer League. Were considered as independent variables the number of injuries, the body part of the injury, affected tissue, affected side, type of incidence, and occurrence of the injury. To measure the incidence of injuries, official medical reports were considered, by an observer previously trained in recording data. A descriptive analysis of the dependent variables was carried out. To analyze the relationship between variables, Chi-square, Cramer's Phi Coefficient, and Corrected Standardized Residuals were used. The sample distribution was analyzed (Kolmogorov-Smirnov). As the sample presented a non-normal distribution, the Mann-Whitney and Kruskal Wallis test were used (SPSS software). The results show the U-18A (X̅=2.55 injuries/player), obtaining significant differences with the rest of the age-categories (exception U-18C). The category does not influence the body part of the injury, the affected side and affected tissue, the type of incidence, and the occurrence of injury. The context influences the body part of injury (p=0.000). On the contrary, there are no significant differences between the affected side, the affected tissue, and the type of incidence.
