Grijota, Diego Muñoz, Marcos Maynar-Mariño. Dominio público. application/pdf Background: Physical training produces changes in the extracellular and intracellular concentrations of trace minerals elements. To our knowledge, only three compartments have been studied simultaneously. The aim of the present study was to analyze the influence of physical training on extracellular (serum, plasma and urine) and intracellular (erythrocytes and platelets) concentrations of Copper (Cu). Methods: Forty young men participated in this study. The participants were divided into a training group (TG; n = 20; 18.15 ± 0.27 years; 68.59 ± 4.18 kg; 1.76 ± 0.04 m) and a control group (CG; n = 20; 19.25 ± 0.39 years; 73.45 ± 9.04 kg; 1.79 ± 0.06 m). The TG was formed by semi-professional soccer players from a youth category with a regular training plan of 10 h/week. All of them had been participating in high level competitions and had trained for at least 5 years. Plasma, serum, urine, erythrocyte and platelet samples of Cu were obtained and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Results: The TG showed lower concentrations of Cu in erythrocytes (p < 0.05) despite similar intakes. There were no significant differences in Cu concentrations in plasma, serum, urine and platelets although the trend was similar to that observed in erythrocytes. Conclusions: The assessment of trace element concentrations should be carried out in both extracellular and intracellular compartments to obtain a proper evaluation and to identify possible deficiencies of the element. We believe that additional Cu supplementation is needed in athletes who perform physical training regularly. info:eu-repo/semantics/openAccess.

Documento no disponible en el fondo. Abstract: The aim of this study was to analyse the effects of floater positioning within futsal Gk+3vs3+Gk SSGs on youth players’ tactical and physical performance. An independent measure approach under four experimental conditions was carried out: Floaters Off (FO), Goal Line Floaters (GLF), Lateral Floaters own court sidelines (LFocsl) and Lateral Floaters full court sidelines (LFfcsl). Thirty male futsal players (U19 age category) participated in the study. Players’ activity was assessed using WIMU PROTM and heart rate (HR) was recorded by HR monitors during the SSGs. Results showed significant differences in the physical variables (ρ ≤ 0.05), not finding such differences in the tactical variables analysed. However, significant differences were observed in relation to the spatial occupation areas. GLF is related to higher distance and speed variables, being the most demanding SSG; in LFocsl, lower HR values were obtained, and FO is linked to the acceleration and deceleration variables, being an indicator of futsal performance. These findings should be considered for the design of futsal training tasks, according to the context (team, players …) and time of the week and the season, since they allow the development of the variables described by optimising training time with the ball.

An analysis according to game principles [Recurso electrónico] / Alba Práxedes, David Pizarro, Bruno Travassos, Miguel Domínguez, Alberto Moreno. Documento no disponible en el fondo. Background: In the last few decades, Nonlinear Pedagogy (NLP) has emerged with the goal to promote a holistic approach through the use of Small-Sided Games (SSG), to optimize specific tactical defensive and offensive behaviours of players. These SSG are designed through the manipulation of relevant task constraints. Specifically, the balance on the number of outfield players is a constraint that has been recently studied because it can change players’ behaviour. However, most of the studies in this domain have only analysed the acute effects of the manipulation of different SSG without any idea about the implications for learning or to improve the transfer between practice tasks to the context of performance. Purpose: The main purpose of this study was to understand the effect of the use of a task of numerical superiority in attack (5 vs 4; NS) before a task of equal number of player in comparison with the use of only two numerical equality (5 vs 5; NE) tasks. A second objective was to examine this effect according to the game principles: keep the ball possession and progress to the goal. Method: Twenty footballers (U14 yrs), grouped in teams of five players, participated in this study. Each team performed two different sequences of SSG (NS + NE and NE + NE) and in two different conditions regarding the game principle. 2176 actions were analysed. Decision-making was measured through the GPET instrument. Also, it was assessed the duration of ball possession and the number of ball touches through a hand notation analysis system. Results: Results show a tendency to decrease the offensive performance in the sequence (NS + NE). However, if we compare both initial situations, significant higher values were observed in the situation with NS. In addition, regarding the two final situations, there are hardly any differences between them. Conclusion: This study highlighted some key pedagogical principles of the constraints-led approach for designing training environment in team games. Coaches in formative stages should promote unequal game situations with superiority number of players in attack, to facilitate the decision-making and develop the technical skills thanks to a greater participation and a greater duration of ball possession. As learning progresses, coaches should design equal situations to facilitate an adaptation to the real game and promote long-term adaptations on players’ performance. Finally, the game principle is another constraint to take into account since it promotes variability and boosts the discovery and exploration of players’ movement solutions.

Vasquez-Bonilla, Alba Camacho-Cardeñosa, Rafael Timón, Ismael Martínez-Guardado, Marta Camacho-Cardeñosa, Guillermo Olcina. Dominio público. application/pdf Abstract: Muscle oxygen consumption could provide information on oxidative metabolism in women soccer players. Therefore, the objective of this study was to analyze muscle oxygenation dynamics during repeated sprint ability (RSA): (8 sprint × 20 s recovery) by near-infrared spectroscopy (NIRS). The sample was made up of 38 professional women soccer players. To measure the external load, the best time, worst time, average time, individual speed, sprint decrement, and power were assessed. In connection with the internal load, the desaturation (sprint) and re-saturation (recovery) rates, as well as the oxygen extraction (∇%SmO2) in the gastrocnemius muscle and maximum heart rate (%HRmax) were measured. A repeated measures statistic was applied based on the inter-individual response of each subject from the baseline versus the other sprints, with linear regression and nonlinear regression analyses between variables. There was an increase in the SmO2 : desaturation rate after four sprints (∆ = 32%), in the re-saturation rate after six sprints (∆ = 89%), and in ∇%SmO2 after four sprints (∆ = 72.1%). There was a linear association between the rates of desaturation and re-saturation relationships and the worst time (r = 0.85), and a non-linear association between ∇%SmO2 and speed (r = 0.89) and between ∇%SmO2 and the sprint decrease (r = 0.93). The progressive increase in SmO2 during RSA is a performance limitation to maintain a high speed; it depends on the capacity of fatigue resistance. Therefore, monitoring the muscle oxygenation dynamics could be a useful tool to evaluate the performance in women soccer players. info:eu-repo/semantics/openAccess.

Dominio público. application/pdf Abstract: The actual coronavirus disease 2019 (COVID-19) pandemic has led to the limit of emergency systems worldwide, leading to the collapse of health systems, police, first responders, as well as other areas. Various ways of dealing with this world crisis have been proposed from many aspects, with fuzzy multi-criteria decision analysis being a method that can be applied to a wide range of emergency systems and professional groups, aiming to confront several associated issues and challenges. The purpose of this critical review was to discuss the basic principles, present current applications during the first pandemic wave, and propose future implications of this methodology. For this purpose, both primary sources, such as scientific articles, and secondary ones, such as bibliographic indexes, web pages, and databases, were used. The main search engines were PubMed, SciELO, and Google Scholar. The method was a systematic literature review of the available literature regarding the performance of the fuzzy multi-criteria decision analysis of emergency systems in the COVID-19 pandemic. The results of this study highlight the importance of the fuzzy multi-criteria decision analysis method as a beneficial tool for healthcare workers and first responders’ emergency professionals to face this pandemic as well as to manage the created uncertainty and its related risks. info:eu-repo/semantics/openAccess.

Dominio público. application/pdf Abstract: The present study examines the association between the success at junior and senior level for British swimmers in World Championships (WCs). It also explores the relationships between swimming performance and the swimmers’ gender, swim stroke, distance, status (finalist, semifinalist and heats) and swimming category. Data were collected for swimmers participating in junior and/or senior World Championships (29,000 entries: 5585 swimmers) from 2006–2017. The final filtered database included only swimmers from the United Kingdom (836 entries: 141 swimmers). A descriptive analysis was made to characterize the swimmers who reached elite status in the senior category. A lineal regression model was run by gender to predict the influence of category, swim stroke, and distance in the results reached in the senior category. The results showed that the ratio of conversion from junior to senior was quite low. Females who participated in both junior and senior WCs were likely to reach top positions in the senior category. Overall, few British swimmers participated in a junior category before the senior level, but female swimmers participating in both junior and senior WCs were likely to reach top positions in the senior category. info:eu-repo/semantics/openAccess.
