Does Acute Beetroot Juice Supplementation Improve Neuromuscular Performance and Match Activity in Young Basketball Players? A Randomized, Placebo-Controlled Study.

Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in team sports has been barely studied. In this randomized placebo-controlled study, we investigated the e ects of BJ acute supplementation in improving neuromuscular performance and physical match activity in basketball. Ten young male competitive basketball players aged 15–16 years received 140 mL of BJ or placebo (PLA) on two separated days in a balanced cross-over design. Testing sessions comprised a neuromuscular test battery consisting of a countermovement jump (CMJ), isometric handgrip strength, 10-m/20-m sprint and agility T-test, followed by a 40-minute simulated basketball match. Physical match activity (distances, speeds, accelerations, and decelerations) was monitored using an inertial tracking system (Wimu ProTM) Results revealed no significant e ects of BJ on CMJ (p = 0.304, ES = 0.13), isometric handgrip strength (p = 0.777, ES = 0.06), 10-m (p = 0.820, ES = 0.10), and 20-m sprint (p = 0.540, ES = 0.13), agility T-test (p = 0.979, ES 0.01) and any physical match demands (p > 0.151, ES = 0.13–0.48). Acute moderate doses of BJ (12.8 mmol of NO3 �����) was not e ective in improving neuromuscular performance (jump height, isometric handgrip strength, sprint, and agility) or physical match requirements in young trained basketball players the day of the competition.post-print2977 K

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Efectos agudos de distintas estrategias de calentamiento sobre el rendimiento físico y las habilidades motrices en escolares

The objective of this research is to assess the effects of different types of warm-ups applied in schoolchildren on the quality of movement of motor skills and jumping and sprint performance. The methodology used was based on a randomized crossover study design (n = 27 schoolchildren), which included three experimental conditions to assess the acute effect of different types of warm-up (traditional, based on reduced adapted games and FIFA 11+) on the vertical jump, sprint in 20 meters and motor skills of locomotion and control of objects in children. Descriptive and comparative statistics were used through repeated measures ANOVA and Friedman with its post-hoc tests as appropriate. The results show that all types of warm-up showed significant differences in sprint, vertical jump and motor skills, compared to the control condition without warm-up. The warm-up based on reduced adapted games presented greater effects than the other modalities on the motor skills of locomotion (p <.05). Comparisons between warm-ups showed that the intervention based on FIFA 11+ was shown to be more effective in reducing sprint time by 20 meters and increasing vertical jump height (p <.05).  In conclusion, this study suggests that the selection of an appropriate strategy based on a diversity of motor experiences such as those offered by the FIFA11 + warm-up protocols and reduced adapted games could be key to improving motor performance and the magnitude of the benefits associated with warm-up.El objetivo de esta investigación fue valorar los efectos de distintos tipos de calentamientos aplicados en escolares sobre la calidad de movimiento de las habilidades motrices y el rendimiento de salto y carrera. La metodología utilizada fue a partir de un diseño estudio cruzado aleatorizado (n=27 escolares), que incluyó tres condiciones experimentales para valorar el efecto agudo de distintos tipos de calentamiento (tradicional, basado en juegos adaptados reducidos y FIFA 11+) sobre el salto vertical, sprint en 20 metros y habilidades motoras de locomoción y control de objetos en niños y niñas. Se utilizó estadística descriptiva y comparativa a través de ANOVA de medidas repetidas y Friedman con sus pruebas post-hoc según corresponda. Los resultados muestran que todos los tipos de calentamiento mostraron diferencias significativas en sprint, salto vertical y habilidades motoras, respecto al a la condición control sin calentamiento. El calentamiento basado en juegos adaptados reducidos presentó efectos superiores que las otras modalidades en las habilidades motoras de locomoción (p< .05). Las comparaciones entre calentamientos mostraron que la intervención basada en FIFA 11+ mostró ser más eficaz en reducir el tiempo de sprint en 20 metros y aumentar la altura del salto vertical (p< .05). En conclusión, este estudio sugiere que, la selección de una estrategia adecuada basada en una diversidad de experiencias motrices como las ofrecidas por los protocolos de calentamiento FIFA11+ y de juegos adaptados reducidos podría ser clave para mejorar el rendimiento motor y la magnitud de los beneficios asociados al calentamiento

Flujos de capitales, choques externos y respuestas de política en países emergentes

Las crisis financieras recientes han incrementado de manera significativa la complejidad de la política económica. Hoy día es necesario estar preparado para enfrentar huracanes financieros que surgen de lugares inesperados y que se expanden alrededor del mundo como reguero de pólvora. Para peor, estas crisis producen un profundo desconcierto entre inversores y analistas —incluyendo al propio Fondo Monetario Internacional—. La presente obra contiene un conjunto importante de artículos de alto calibre profesional que se enfocan sobre los nuevos desafíos que enfrenta la política económica en estas circunstancias. Los artículos estudian las características de los flujos de capitales, tanto en su totalidad como en su composición (capital de cartera, inversión directa, etc.) y su interrelación con el mercado de commodities (café y petróleo, en particular). Esto se complementa con un estudio cuidadoso de las vulnerabilidades financieras y un detallado análisis del papel de todos estos factores en la economía colombiana. El libro se convierte en un verdadero pionero en esta literatura y debería transformarse en referencia obligada para todos aquellos que quieran entender los nuevos fenómenos y desarrollar herramientas para prevenir sus peores consecuencias o paliar sus costos en economías emergentes, como la colombiana
