Biochemical and Physical Performance Responses to a Soccer Match after a 72-Hour Recovery Period

The physiological and neuromuscular responses at 72 h post-match are not widely researched, despite evidence showing substantial changes in recovery markers at 72 h post-match. Consequently, the aim of this study was to determine the biochemical and physical performance responses to a soccer match after a 72-h recovery period. Male soccer players of a semiprofessional team participated in this study. Before playing a friendly match, blood values of testosterone, cortisol, the testosterone-to-cortisol ratio and urea were collected and the squat jump and the Bangsbo Repeated Sprint Ability test were performed. These measurements were considered as baseline (pre match) and were obtained again after a 72-h recovery period. Results indicate that physical performance at 72 h post-match was similar to baseline (squat jump: p = 0.974; total Repeated Sprint Ability time: p = 0.381; Repeated Sprint Ability fatigue index: p = 0.864). However, perturbations in the biochemical milieu derived from the soccer match metabolic and physiological stress were still evident at this time point. While no significant differences compared to pre match were obtained in testosterone and urea concentrations after the recovery period, cortisol and testosterone-to-cortisol ratio values were significantly higher (14.74 ± 3.68 µg/dL vs. 17.83 ± 2.65 µg/dL; p = 0.045; ES 0.92 [0.00; 1.84], very likely) and lower (39.08 ± 13.26 vs. 28.29 ± 7.45; p = 0.038; ES −0.96 [−1.89; −0.04], very likely), respectively. In conclusion, soccer players have similar physical performance to the pre match after a 72-h recovery period, even with signs of biochemical and physiological stress

Match Loads May Predict Neuromuscular Fatigue and Intermittent-Running Endurance Capacity Decrement after a Soccer Match

How the match-derived load metrics relate to post-match fatigue in soccer is scarcely researched. Thus, the aim of this study was to determine the associations between soccer match-related internal and external loads, neuromuscular performance decrease and intermittent-running endurance capacity decrement immediately post-match. Vertical jump (countermovement jump), straight-line sprinting (10- and 20-m sprint), change of direction ability (T-test) and intermittent-running endurance capacity (YO-YO intermittent recovery level 2) were measured one day before and immediately after a friendly match in male soccer players. During the match, players’ internal and external loads were also monitored, including heart rate-derived indices, total distance at various speed thresholds, average running velocity, maximal running velocity, number of sprints and number of accelerations and decelerations at various intensity thresholds. The results show that match-induced fatigue was reflected on neuromuscular performance and intermittent-running endurance capacity immediately post-match (p < 0.05). The quantification of percentage change of match external-load metrics, particularly accelerations and decelerations, provides a useful non-invasive predictor of subsequent neuromuscular fatigue status in soccer players immediately post-match (p < 0.05). However, only internal load metrics present a practical application for predicting intermittent-running endurance capacity impairment (p < 0.05). In summary, internal and external load metrics may allow for predicting the extent of acute fatigue, and variability between halves may represent a valuable alternative to facilitate the analysis of match-related fatigue both for research and applied purposes

Impacto en la autoestima y en la Salud Mental provocado por el uso continuado de las redes sociales

Hoy en día, con el gran avance y auge de la tecnología, son cada vez más, las personas que pasan un mayor tiempo delante de las pantallas, conectadas a Internet y a las redes sociales. Todo ello, está acarreando un impacto enorme en la sociedad, y a nivel mundial. Este estudio pretende dar a conocer las consecuencias que pueden provocar el mal uso de ellas tanto en la Salud Mental como en la autoestima. Para lograr la consecución de los objetivos establecidos, se diseñó una encuesta, que se lanzó a personas entre los 16 y 64 años, para poder hacer una comparación del uso entre las diferentes franjas de edad. Los principales resultados a destacar son que, para el 91.4% que hacen uso de las redes sociales, WhatsApp, Instagram y Facebook son las más utilizadas. Además, el tiempo medio que pasan conectados a las redes sociales es entre 3 y 6 horas, conllevando un mayor tiempo los más jóvenes. En definitiva, las personas opinan que las redes sociales afectan a las personas en muchos factores, como por ejemplo en la privacidad, rendimiento, etc. Es por ello, que, con los resultados obtenidos, se propondrán una serie de recomendaciones para solucionar el posible mal uso que ciertas personas hacen de las redes sociales. <br /

Plan de intervención de fisioterapia para la reincorporación deportiva en un caso de esguince del ligamento lateral interno de rodilla: a propósito de un caso.

Introducción: en la lesión de la articulación de la rodilla, el deporte supone el 80% de la etiología. Dentro de las lesiones más comunes de la rodilla, los esguinces ocupan el 27,3%. Estas disfunciones de rodilla provocan déficits funcionales y una disminución de la calidad de vida. Por este motivo, es fundamental una intervención de fisioterapia para la recuperación del movimiento y de la función. Objetivo: diseñar y comprobar la efectividad de un programa de intervención de fisioterapia para la reincorporación deportiva en un sujeto con un esguince grado II del ligamento interno de rodilla. Metodología: diseño intrasujeto (n=1, caso clínico) test-retest en el que se realizó un examen fisioterápico valorando el dolor, función de la rodilla, movilidad articular, fuerza muscular y perimetría. Se realizaron 10 sesiones presenciales de 45 minutos en los que se aplicaron diferentes técnicas de fisioterapia y se enseñaron los ejercicios que debía hacer diariamente en su domicilio. Desarrollo: la aplicación del tratamiento basado principalmente en un entrenamiento de fuerza y propiocepción, produjo una mejora importante de los síntomas y un aumento de la fuerza del miembro inferior afecto y de la estabilidad de la rodilla. Conclusiones: tras la intervención de fisioterapia se produce una disminución del dolor durante la práctica de la actividad deportiva y después de la misma; un aumento de la fuerza de la extremidad afecta, un incremento considerable de la estabilidad de la rodilla y una mejora en la funcionalidad de la rodilla y en la calidad de vida.<br /

Soil Degradation and Soil Quality in Western Europe: Current situation and future perspectives

Abstract: The extension and causes of soil chemical, physical and biological degradation, and of soil loss, varies greatly in different countries in Western Europe. The objective of this work was to review these issues, the strategies for soil protection, and the future perspectives for soil quality evaluation, under the light of present legislation for soil protection. Agriculture and forestry are responsible for many of them, especially for physical degradation, erosion and organic matter loss. Land take and soil sealing have increased in the last decades and can enhance these problems. In agricultural land, conservation farming, organic farming and other soil-friendly practices have been seen to have site-specific effects, depending on the characteristics of soils and the particularities of land uses and land users. No single soil management strategy suitable for all regions, soil types and soil uses exists. Except for soil contamination, specific legislation for soil protection is lacking in the region. The development of a Thematic Strategy for Soil Protection in the European Union has produced valuable information and the development of networks and databases. However, soil degradation is addressed only indirectly in environmental policies, and through the Common Agricultural Policy of the European Union, which encourages farming practices supporting soil conservation. Despite these efforts, there is still a need for soil monitoring networks and decision-support systems based in soil quality optimization in the region. The pressure to European soils will continue in the future, and a clear regulatory framework is needed.JRC.H.5-Land Resources Managemen

Neonatal feeding trajectories in mothers with bipolar disorder taking lithium: pharmacokinetic data

Purpose: Women who take lithium during pregnancy and continue after delivery may choose to breastfeed, formula feed, or mix these options. The aim of the study was to evaluate the neonatal lithium serum concentrations based on these three feeding trajectories. Methods: We followed 24 women with bipolar disorder treated with lithium monotherapy during late pregnancy and postpartum (8 per trajectory). Lithium serum concentrations were determined by an AVL 9180 electrolyte analyser with a 0.10 mEq/L detection limit and a 0.20 mEq/L limit of quantification (LoQ). Results: There was complete lithium placental passage at delivery, with a mean ratio of lithium concentration in the umbilical cord to maternal serum of 1.12 ± 0.17. The median times to LoQ were 6–8, 7–8, and 53–60 days for formula, mixed, and exclusive breastfeeding respectively. The generalized log-rank testing indicated that the median times to LoQ differ according to feeding trajectory (p = 0.037). According to the multivariate analysis-adjusted lithium serum concentrations at birth, times to LoQ are, on average, longer under exclusive breastfeeding (formula, p = 0.015; mixed, p = 0.012). No lithium accumulation was observed in infants under either exclusive or mixed breastfeeding. During the lactation follow-up, there was no acute growth or developmental delays in any neonate or infant. Indeed, lithium concentrations in the three trajectories declined in all cases. However, the time needed to reach the LoQ was much longer for those breastfeeding exclusively. Conclusions: In breastfeed infant no sustained accumulation of lithium and no adverse effects on development or growth were observed.Peer ReviewedPostprint (published version
