Diseño e implementación de componentes software para dar soporte a la plataforma MEWiN en el sistema operativo Contiki

El presente proyecto final de carrera que tiene como título: "Diseño e Implementación de componentes software para dar soporte a la plataforma MEWiN en el sistema operativo Contiki" pretende dar soporte software al dispositivo MEWiN desarrollado. En la actualidad el sistema operativo Contiki es uno de los más utilizados en el ámbito de las redes inalámbricas de sensores, dada su característica de código libre y su alta escalabilidad. La mayoría de fabricantes de dispositivos electrónicos usados en redes de sensores tienen en proyecto dar soporte en este sistema operativo a sus equipos, con lo que se ha considerado importante compatibilizar un dispositivo hardware desarrollado en el seno de la universidad con un sistema operativo tan popular y con las ventajas de Contiki. Para llevar a cabo esta labor, el proyecto se ha desarrollado en varias fases que, en si mismas, constituyen objetivos intermedios del proyecto: 1) Búsqueda, estudio y análisis del estado del arte en dispositivos WSN y en sistemas operativos. 2) Análisis de las limitaciones del sistema ZigBee de Texas utilizado en el sistema MEWiN actualmente. Comparativa con Contiki 3) Instalación y configuración del sistema operativo Contiki en Ubuntu bajo LINUX. 4) Adaptación del sistema para poder compilar y cargar código en el dispositivo MEWIN. 5) Creación de las bibliotecas necesarias para poder utilizar de manera intuitiva y sencilla los periféricos de MEWiN en Contiki: modulo de almacenamiento en tarjeta SD, RTC y módulo de radio.Escuela Técnica Superior de Ingeniería IndustrialUniversidad Polítécnica de Cartagen

Effect of ACTN3 R577X Genotype on Injury Epidemiology in Elite Endurance Runners´.

The p.R577X polymorphism (rs1815739) in the ACTN3 gene causes individuals with the ACTN3 XX genotype to be deficient in functional α-actinin-3. Previous investigations have found that XX athletes are more prone to suffer non-contact muscle injuries. This investigation aimed to determine the influence of the ACTN3 R577X polymorphism in the injury epidemiology of elite endurance athletes. Using a cross-sectional experiment, the epidemiology of running-related injuries was recorded for one season in a group of 89 Spanish elite endurance runners. ACTN3 R577X genotype was obtained for each athlete using genomic DNA samples. From the study sample, 42.7% of athletes had the RR genotype, 39.3% had the RX genotype, and 18.0% had the XX genotype. A total of 96 injuries were recorded in 57 athletes. Injury incidence was higher in RR runners (3.2 injuries/1000 h of running) than in RX (2.0 injuries/1000 h) and XX (2.2 injuries/1000 h; p = 0.030) runners. RR runners had a higher proportion of injuries located in the Achilles tendon, RX runners had a higher proportion of injuries located in the knee, and XX runners had a higher proportion of injuries located in the groin (p = 0.025). The ACTN3 genotype did not affect the mode of onset, the severity, or the type of injury. The ACTN3 genotype slightly affected the injury epidemiology of elite endurance athletes with a higher injury rate in RR athletes and differences in injury location. However, elite ACTN3 XX endurance runners were not more prone to muscle-type injuries.post-print248 K

Intelligent thermal image-based sensor for affordable measurement of crop canopy temperature

Crop canopy temperature measurement is necessary for monitoring water stress indicators such as the Crop Water Stress Index (CWSI). Water stress indicators are very useful for irrigation strategies management in the precision agriculture context. For this purpose, one of the techniques used is thermography, which allows remote temperature measurement. However, the applicability of these techniques depends on being affordable, allowing continuous monitoring over multiple field measurement. In this article, the development of a sensor capable of automatically measuring the crop canopy temperature by means of a low-cost thermal camera and the implementation of artificial intelligence-based image segmentation models is presented. In addition, we provide results on almond trees comparing our system with a commercial thermal camera, in which an R-squared of 0.75 is obtained.This research was funded by the Agencia Estatal de Investigación (AEI) under project numbers: AGL2016-77282-C3-3-R, and PID2019-106226-C22 AEI/https://doi.org//10.13039/501100011033.

Genetics and sports performance: the present and future in the identification of talent for sports based on DNA testing.

The impact of genetics on physiology and sports performance is one of the most debated research aspects in sports sciences. Nearly 200 genetic polymorphisms have been found to influence sports performance traits, and over 20 polymorphisms may condition the status of the elite athlete. However, with the current evidence, it is certainly too early a stage to determine how to use genotyping as a tool for predicting exercise/sports performance or improving current methods of training. Research on this topic presents methodological limitations such as the lack of measurement of valid exercise performance phenotypes that make the study results difficult to interpret. Additionally, many studies present an insufficient cohort of athletes, or their classification as elite is dubious, which may introduce expectancy effects. Finally, the assessment of a progressively higher number of polymorphisms in the studies and the introduction of new analysis tools, such as the total genotype score (TGS) and genome-wide association studies (GWAS), have produced a considerable advance in the power of the analyses and a change from the study of single variants to determine pathways and systems associated with performance. The purpose of the present study was to comprehensively review evidence on the impact of genetics on endurance- and power-based exercise performance to clearly determine the potential utility of genotyping for detecting sports talent, enhancing training, or preventing exercise-related injuries, and to present an overview of recent research that has attempted to correct the methodological issues found in previous investigations.post-print1358 K

Placebo Effect of Caffeine on Substrate Oxidation during Exercise

By using deceptive experiments in which participants are informed that they received caffeine when, in fact, they received an inert substance (i.e., placebo), several investigations have demonstrated that exercise performance can be enhanced to a similar degree as a known caffeine dose. This ‘placebo effect’ phenomenon may be part of the mechanisms explaining caffeine’s ergogenicity in exercise. However, there is no study that has established whether the placebo effect of caffeine is also present for other benefits obtained with acute caffeine intake, such as enhanced fat oxidation during exercise. Therefore, the aim of this investigation was to investigate the placebo effect of caffeine on fat oxidation during exercise. Twelve young men participated in a deceptive doubleblind cross-over experiment. Each participant completed three identical trials consisting of a step incremental exercise test from 30 to 80% of . VO2max. In the two first trials, participants ingested either 3 mg/kg of cellulose (placebo) or 3 mg/kg of caffeine (received caffeine) in a randomized order. In the third trial, participants were informed that they had received 3 mg/kg of caffeine, but a placebo was provided (informed caffeine). Fat oxidation rates were derived from stoichiometric equations. In received caffeine, participants increased their rate of fat oxidation over the values obtained with the placebo at 30%, 40%, 50%, and 60% of . VO2max (all p < 0.050). In informed caffeine, participants increased their rate of fat oxidation at 30%, 40%, 50% 60%, and 70% of . VO2max (all p < 0.050) over the placebo, while there were no differences between received versus informed caffeine. In comparison to placebo (0.32 ± 0.15 g/min), the rate of maximal fat oxidation was higher in received caffeine (0.44 ± 0.22 g/min, p = 0.045) and in informed caffeine (0.41 ± 0.20 g/min, p = 0.026) with no differences between received versus informed caffeine. However, the intensity at which maximal fat oxidation rate was obtained (i.e., Fatmax) was similar in placebo, received caffeine, and informed caffeine trials (42.5 ± 4.5, 44.2 ± 9.0, and 41.7 ± 10.5% of . VO2max, respectively, p = 0.539). In conclusion, the expectancy of having received caffeine produced similar effects on fat oxidation rate during exercise than actually receiving caffeine. Therefore, the placebo effect of caffeine is also present for the benefits of acute caffeine intake on substrate oxidation during exercise and it may be used to enhance fat oxidation during exercise in participants while reducing any risks to health that this substance may have.Francisco de Vitoria University UFV-18/202
