Effects of a strength and stretching program, combined or Iisolated, on active flexibility in physical education setting.

Purpose. To examine the effects of a two-session-per-week strength and stretching program on sit and reach score among high-school students in the physical education setting. Methods. A sample of 46 high-school students (16 girls and 30 boys) aged 12-14 years from four classes were clustered and randomly assigned to a strength group (n=8), a stretching group (n=12), a strength + stretching group (n=16) or a control group (n=10). During physical education classes, the experimental students performed a 1-minute stretching, a 1-minute strength or a 2-minutes strength + stretching program twice a week a total of 20 weeks. Control students performed the same physical education classes, but they did not follow any strength and/or stretching program. Active flexibility (estimated by the classic sit-and-reach test) was assessed at the beginning and at the end of the intervention program. Results. The Wilcoxon test results showed that students that performed a combined strength and stretching program increased statistically significantly their active flexibility levels from pre-intervention to post-intervention (∆ = 1.8 ± 3.2 cm; p 0.05). Conclusiones. Since in physical education many curricular contents need to be developed each academic year and the subject is also restricted by its limited curriculum time allocation, teachers could improve students’ flexibility combining stretching and strength workout. Therefore, in addition to the improvement of students’ flexibility levels, this intervention program might permit regular development of other physical education curricular contents.Universidad de Málaga.

Differences according to modalities, distances and genders of how the triathletes carry their bicycles for the boxes during the first transition in the Spanish Championships

Introduction The purpose was to compare the proportion in the use (by elite or pro category) of the 4 types of hold-riding the bicycle during the transition between triathletes’ sex (men and women), distance or modality (Olympic, sprint, long and cross) at the Triathlon Spanish Championships. Method The sample was composed by 648 Spanish triathletes, participants of eight elite Spanish championship triathlon during 2016. Results Most of triathletes hold-ride the bike by the seat only while driving it (76.2%), followed by the handlebar (14.9%), seat-handlebar (7.1%) and stem styles (1.9%). The same tendency was showed within sex, category and race subcategories, except for Olympic (seat style was used for the 95% of triathletes), sprint (seat and handlebar styles were similar), and long (seat-handlebar and stem styles were equal). The results showed that there were statistically significantly differences in the proportion of triathletes that used each hold-riding of the bicycle between sex, race, and sex-race subcategories (p 0.05; Cramer´s V = 0.000-0.244). Discussion The difference between men and women is that men have twice the grip on the handlebars. The videos show that this may be because the groups of men in the boxes are greater than those of the women, and this sometimes forces them, to take the bike by the handlebar to control it better and avoid incidents. While in the Olympic, sprint and long-distance elite triathletes mostly used the seat style, and in the cross race the handlebar style.Universidad de Málaga.

Comparison of the effect of a Physical Education-Based Stretching Program applied during the Warm-Up, ColdDown and both periods on hamstring extensibility in Primary Schoolchildren.

Purpose. To compare the effects of a physical education-based stretching program applied during the warm-up, cold-down and both periods on hamstring extensibility in primary schoolchildren. Methods. A sample of 237 schoolchildren aged 7-12 years old (128 girls and 109 boys) from two primary school centres participated in the present study and met satisfactorily the inclusion and exclusion criteria. A cluster randomized controlled trial design was used. The classes balanced by grade were randomly assigned to the warm-up (n = 57), cold-down (n = 55), both periods (n = 61) or control groups (n = 64). During the physical education sessions, the students from the interventional groups performed a four-minute stretching program twice a week for eight weeks. The intervention program was applied during the warm-up (4 minutes), cold-down (4 minutes) and warm-up (2 minutes)-cold-down (2 minutes) for the warm-up, cold-down and both periods groups, respectively. Hamstring extensibility (estimated by the back-saver sit-and-reach test) was assessed at the beginning and at the end of the intervention program. Results. The one-way ANOVA (p 0.05). Conclusions. In order to develop students’ flexibility, PE teachers should apply stretching programs during the cold-down period. Due to the negative effect of static stretching on performance as previously found in the literature, it seems that PE teachers should improve students´ flexibility during the cool-down period of the sessions.Universidad de Málaga.

Promoting light hydrocarbons yield by catalytic hydrodechlorination of residual chloromethanes using palladium supported on zeolite catalysts

Gas catalytic hydrodechlorination (HDC) of trichloromethane (TCM) and dichloromethane (DCM) was analyzed using Pd (1 wt.%) on different zeolites as catalysts. The aim of this study was to know the surface properties of the catalysts and reaction conditions that promote the yield to light hydrocarbons in this reaction. Five different zeolite supports were used from three commercial zeolites (KL, L-type; NaY, Faujasite; H-MOR, Mordenite). KL and NaY were submitted to ionic exchange treatments in order to increase their acidity and analyze the effect of the acidity in the activity and selectivity of the HDC reaction. Exchanged zeolites (HL and HY) showed the highest Pd dispersion due to their higher surface acidity. The best TCM/DCM conversion and selectivity to light hydrocarbons was obtained using the two non-exchanged zeolite-catalysts, KL and NaY. Low surface acidity seems to be the key aspect to promote the formation of light hydrocarbons. The formation of these products is favored at high reaction temperatures and low H2: chloromethane ratios. KL showed the highest selectivity to olefins (60%), although with a lower dechlorination degree. Non-exchanged NaY catalyst showed high selectivity to paraffins (70% and 95% for the HDC of DCM and TCM, respectively)Authors gratefully acknowledge financial support from FEDER/Ministerio de Ciencia, Innovación y Universidades—Agencia Estatal de Investigación/ CTM2017-85498-R.

Simulador de comportamiento de enjambre con Quorum Sensing bacteriano

One of the most useful tools in the design of path-planning solutions is simulators. Thanks to them, it is possible to predict the performance of certain control strategies. In this paper, a simulator is presented that implements a swarm of automatons, which perform a wild motion in a user-selected environment. The robots will have the quality to avoid collisions with different obstacles that affect their mobility since they are equipped with proximity sensors. The interface of this simulator was designed entirely with the Qt Designer software. Successful configurations that replicate the performance of the real prototype are presented.  Una de las herramientas más útiles en el diseño de soluciones de planificación de trayectorias son los simuladores. Gracias a ellos, es posible predecir el rendimiento de determinadas estrategias de control. En este trabajo se presenta un simulador que implementa un enjambre de autómatas que realizan un movimiento salvaje en un entorno seleccionado por el usuario. Los robots tendrán la cualidad de evitar colisiones con diferentes obstáculos que afecten a su movilidad ya que están equipados con sensores de proximidad. La interfaz de este simulador se ha diseñado íntegramente con el software Qt Designer. Se presentan configuraciones exitosas que replican el desempeño del prototipo real. &nbsp

Midiendo el Sentimiento del Ciclo Económico Nacional a través de los pronunciamientos del Banxico

Se elabora un indicador de confianza con los anuncios de política monetaria de Banco de México (Banxico) para revisar el comportamiento del ciclo económico contemporáneo. La metodología consiste en identificar los enunciados que hacen los miembros de la junta de gobierno del banco central en relación a su evaluación del ritmo de la actividad económica reciente y se transforman en un índice. Los resultados muestran un indicador cíclico con respecto a la trayectoria de la economía en el período enero 2003-enero 2011, por lo que puede ser usado en el análisis oportuno de la situación económica del país dado el rezago de la publicación de indicadores que describen la evolución del ciclo tal como el Producto Interno BrutoCiclo económico, indicadores de confianza, política monetaria

A definitive version was subsequently published in Pattern Recognition Letters 26.16 (2005): 2628 – 2639, DOI: 10.1016/j.patrec.2005.06.008A novel adapted strategy for combining general and user-dependent knowledge at the decision-level in multimodal biometric authentication is presented. User- independent, user-dependent, and adapted fusion and decision schemes are com- pared by using a bimodal system based on ¯ngerprint and written signature. The adapted approach is shown to outperform the other strategies considered in this pa- per. Exploiting available information for training the fusion function is also shown to be better than using existing information for post-fusion trained decisions.This work has been supported by the Spanish Ministry for Science and Tech- nology under projects TIC2003-09068-C02-01 and TIC2003-08382-C05-01
