Implementation of an autonomy support program during Physical Education lessons
El objetivo de este estudio es conocer los efectos de un programa basado en el soporte de autonomía a través de las clases de Educación Física sobre las necesidades psicológicas básicas, la regulación conductual y la percepción del estilo interpersonal del docente. Los participantes del estudio fueron 61 alumnos (25 chicos y 36 chicas) con edades comprendidas entre los 14 y los 17 años de edad (M = 14.97; DT = .85), pertenecientes a dos Centros Educativos españoles. Los estudiantes fueron divididos aleatoriamente en dos grupos (control y experimental). Los instrumentos utilizados fueron la Escala de Satisfacción de Necesidades Psicológicas Básicas, el Cuestionario de la Regulación Conductual en el Deporte y el Cuestionario de Estilo interpersonal del docente. Los profesores aplicaron en el grupo experimental el programa basado en el soporte de autonomía durante las clases de Educación Física en un total de ocho semanas. Los resultados indicaron diferencias estadísticamente significativas respecto a la relación con los demás (p<.01) y a la percepción del estilo autónomo del docente (p<.05), no encontrándose diferencias significativas respecto al resto de variables. Como conclusión principal indicar que un programa basado en el fomento de la autonomía, puede ser óptimo para el incremento de las relaciones entre los alumnos
Analysis of performance parameters of the smash in male and female professional padel
The aim of this study was to analyze the distribution and effectiveness of the different types of smash in professional padel according to the area and direction of the strokes and the gender. Through systematic observation, 1.015 smashes from eight finals (four men’s and four women’s) of the professional matches were analyzed. The smashes were categorized into four types of smash: tray, flat, topspin and off the wall. The results showed both men’s and women’s that the tray is the most used smash by padel players, presenting a percentage of point continuity of almost 90%. The flat and topspin smashes are the strokes that achieve the highest percentage of winning points (near 60%), although this efficiency decreases significantly when the players move away from the net area (p < 0.05), especially in the flat smash. Men perform a higher percentage of winning smashes than women, mainly in the flat smash (p = 0.02). Furthermore, with regards to direction, flat and off the wall smashes are predominantly down the line strokes and women perform significantly more cross court topspin smashes than men (p = 0.005). The results shown could be used to design tasks and exercises by padel coaches at professional players
Effect of a padel match on biochemical and haematological parameters in professional players with regard to gender-related differences
Haematological and biochemical parameters have not yet been analysed in professional padel players. The aim of this study was to determine the basal values of these parameters and to observe the effect of a simulated competition on them, including gender-related differences. A total of 14 male professional players (age: 28.2 ± 7.9 years), and 16 female professional players (age: 29.7 ± 3.7 years) participated in this study. Players were allowed to hydrate ad libitum during the matches. Haematological and biochemical values were obtained before and after a simulated competitive padel match. The men’s group showed higher baseline values in red blood cells, haematocrit, haemoglobin, urea, creatinine, uric acid, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), lactate dehydrogenase (LDH) and creatine kinase (CK) (p < 0.01) than the women’s group. Attending to match effect, significant differences were obtained in urea, creatinine, CK and glucose (p < 0.05). Finally, the group x match interaction revealed significant differences in serum concentrations of sodium and chloride (p < 0.05). In conclusion, high-level padel matches provoke several changes in biochemical parameters related to muscle damage and protein catabolism. Recovery and fluid intake strategies could be added regarding gender. The results obtained could be due to the differences in the intensity and volume of the simulated competition
Aplicación de un programa basado en el soporte de autonomía en las clases de Educación Física
The purpose of this study is to know the effects of a autonomy support program through the Physical Education lessons on the psychological needs satisfaction, behavioral regulation and teacher interpersonal style. Sample were 61 students (25 boys and 36 girls) aged between 14 and 17 years (M = 14.97; DT = .85), belonging to two educational centres in Spain. Students were randomly divided In two groups (control and experimental). The instruments used were the Basic Psychological Needs Satisfaction Scale, the Behavioral Regulation Questionnaire in Sport and the Interpersonal Teacher Style Questionnaire. The teachers applied in the experimental group the autonomy support program during the Physical Education lessons in a total of eight weeks. The results showed statistically significant differences regarding the relation with the others (p<.01) and the perception of teacher autonomous style (p<.05), not finding significant differences with respect to the other variables. As a main conclusion to indicate that a program based on the promotion of autonomy may be optimal for the increase relations between students.El objetivo de este estudio es conocer los efectos de un programa basado en el soporte de autonomía a través de las clases de Educación Física sobre las necesidades psicológicas básicas, la regulación conductual y la percepción del estilo interpersonal del docente.

Estado de ánimo y calidad de vida en mujeres adultas practicantes de pádel
The purpose of this study is to analyze the level of quality of life and to determine the profile of mood state in adult padel women and to compare it with sedentary women. The sample were 60 women from Extremadura (average age = 40,43 ± 5,73 years), divided into two groups, distinguishing between sportswomen who practice paddle and sedentary women. The International Physical Activity Questionnaire was used to clasify the participants in the groups (athletes and sedentary). The questionnaire of the Mood Profile and a quality of life questionnaire (EuroQol-5D) were applied. The results of this work showed higher levels in every dimension of mood state for the group of sportswomen. However, it does not appear that practicing padel influence on the dimensions of quality of life, outside of the measure in the analog visual scale, which is higher in the women padel players.El objetivo de este estudio es analizar la percepción del nivel de calidad de vida y determinar el perfil de estado de ánimo de las mujeres deportistas que practican pádel y compararlo con los resultados obtenidos por las mujeres sedentarias. Las participantes del estudio fueron 60 mujeres extremeñas (Edad media = 40,43 ± 5,73 años), divididas en dos grupos, distinguiendo entre mujeres deportistas que practican pádel y mujeres sedentarias. Se utilizó el Cuestionario Internacional de Actividad Física para dividir a las participantes en dos grupos (deportistas y sedentarias) y posteriormente se aplicó cuestionario del Perfil de Estado de Ánimo y el test EuroQol-5D para conocer la percepción de calidad de vida. Los resultados de este trabajo mostraron valores significativamente más elevados en el todas las dimensiones del estado de ánimo en las mujeres deportistas. Sin embargo, no parece que la práctica de pádel influya significativamente en las dimensiones de calidad de vida excepción de la medida en la escala visual analógica, que es superior en las mujeres practicantes de páde
Doping Liquid Argon with Xenon in ProtoDUNE Single-Phase: Effects on Scintillation Light
International audienceDoping of liquid argon TPCs (LArTPCs) with a small concentration of xenon is a technique for light-shifting and facilitates the detection of the liquid argon scintillation light. In this paper, we present the results of the first doping test ever performed in a kiloton-scale LArTPC. From February to May 2020, we carried out this special run in the single-phase DUNE Far Detector prototype (ProtoDUNE-SP) at CERN, featuring 770 t of total liquid argon mass with 410 t of fiducial mass. The goal of the run was to measure the light and charge response of the detector to the addition of xenon, up to a concentration of 18.8 ppm. The main purpose was to test the possibility for reduction of non-uniformities in light collection, caused by deployment of photon detectors only within the anode planes. Light collection was analysed as a function of the xenon concentration, by using the pre-existing photon detection system (PDS) of ProtoDUNE-SP and an additional smaller set-up installed specifically for this run. In this paper we first summarize our current understanding of the argon-xenon energy transfer process and the impact of the presence of nitrogen in argon with and without xenon dopant. We then describe the key elements of ProtoDUNE-SP and the injection method deployed. Two dedicated photon detectors were able to collect the light produced by xenon and the total light. The ratio of these components was measured to be about 0.65 as 18.8 ppm of xenon were injected. We performed studies of the collection efficiency as a function of the distance between tracks and light detectors, demonstrating enhanced uniformity of response for the anode-mounted PDS. We also show that xenon doping can substantially recover light losses due to contamination of the liquid argon by nitrogen

A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force-the W+, W-, and Z(0) bosons-as well as to the fundamental quarks and leptons. The CMS Collaboration has observed, with a statistical significance of five standard deviations, a new particle produced in proton-proton collisions at the Large Hadron Collider at CERN. The evidence is strongest in the diphoton and four-lepton (electrons and/or muons) final states, which provide the best mass resolution in the CMS detector. The probability of the observed signal being due to a random fluctuation of the background is about 1 in 3 x 10(6). The new particle is a boson with spin not equal to 1 and has a mass of about 1.25 giga-electron volts. Although its measured properties are, within the uncertainties of the present data, consistent with those expected of the Higgs boson, more data are needed to elucidate the precise nature of the new particle
