Objective: To carry out an epidemiological analysis characterizing the type and location of the injury, severity based on recovery time, game position, and injury for hours of exposure. Methods: Data collection was carried out in the sub 15, sub 17, and sub 20 categories and verified records made by the medical team of the club, which was trained to use the F-MARC form (a form of the medical research center of the International Football Federation - FIFA) at the beginning of the season. To perform the data analysis, the GraphPad Prism software was used. All variables were analyzed using the Kolmogorov-Smirnov test. Results: In relation to the 129 athletes monitored during the season, 62 athletes presented some injury during the season, presenting 42.2 injuries for every 1000 hours of play, the Sub 15 category was the one with the highest incidence of injury, followed by the Sub17 and U20. The average time of leave after injury was 3.65 ± 4.2 weeks, the Defenders were the ones with the highest injury rate. There were 27 articular injuries (43.54%), 25 muscle injuries (40.32%), 9 bone injuries (15.41%), and one pathological injury (1.61%), and the most affected regions were ankle and knee. Conclusion: It is concluded that the moment of the game is the moment when the greatest number of injuries occurs, having a greater incidence in the athletes of the category Sub 15, the Defenders suffered more injuries and the Lower Limbs were more affected, mainly by articular traumas.

IntroductionWork accidents (WA) in agriculture are a problem all over the world. There are over 1,3 billion agricultural workers, that counts more than 50% of all the worlds’ workforce. Even if the most of work tasks become more automated, farmers, family members and farm workers are facing risks at work that are higher than in most other occupations. Many accidents involve the handling of machinery or animals. The costs of WAs are increasing, exhausting national economy as a whole. The aim of this study is to analyse the main causes and consequences of WAs in Estonian agriculture.MethodThe database of accidents in agriculture (2008–2017) has obtained from the Estonian Labour Inspectorate. WAs statistics is based on official reports of employers. Causes and consequences including injury severity, type and body region are described in the present study.ResultsThe main cause of WAs in agriculture is disregarding of safety requirements (28,9%), whereas more than half of cases remain unclear. Loss of control over animals or machinery (33,4%), falling and slipping (21,5%) and an attack or an assault by cattle (15,8%) are the main activity-based reasons of WAs. During the last decade the most were minor injuries (72,8%). By the type of injury most often wounds and superficial injuries (40,4%), bone fractures (25,6%) and concussion or internal injuries (16,2%) have been registered. Upper and lower limbs (35,7% and 33,6%) were the most often injured body regions.ConclusionsAgriculture is a sector with high accident risks, where injury rate shows steady tendency to increase. It is important to pay more attention on improvement of safety culture and prevention of work accidents in agriculture.

Resumen Objetivo: Analizar la relación existente según el género, la edad y el nivel de los jugadores de pádel con la cantidad de lesiones descritas por ellos mismos. Método: Participaron 148 jugadores (75 hombres, 73 mujeres, 33.95 ± 9.87 años). Se registraron un total de 151 lesiones clasificadas en función del tipo de lesión, localización anatómica y situación (entrenamiento o competición). Estudio descriptivo retrospectivo utilizando una adaptación de un cuestionario de lesiones deportivas autocompletado por los jugadores. Se utilizó la prueba de Chi-Cuadrado, los Residuos y la V de Cramer para conocer el grado de asociación entre las variables. Resultados: Los resultados mostraron: i) predominio de lesiones musculares en los miembros inferiores; ii) alto número de lesiones en el tronco en hombres y de los miembros superiores en mujeres (p = 0.046); iii) mayor índice de lesiones musculares en mayores de 35 años y tendinosas en menores de 35 años (p = 0.009); iv) mayor número de lesiones en jugadores de menor nivel, especialmente en tendones y hombro (p = 0.031). Conclusiones: Las lesiones más frecuentes en pádel son las musculares, localizadas en los miembros inferiores. El género masculino presenta más lesiones en el tronco mientras que el número de lesiones en mujeres se centra en el miembro superior. Los jugadores mayores de 35 años presentaron más lesiones musculares mientras que se registró un mayor número de lesiones tendinosas en menores de 35 años. Finalmente, el nivel de los jugadores está relacionado inversamente con el número de lesiones (a mayor nivel, menor número de lesiones). Abstract Objective: To analyze the relationship according to gender, age and level of padel players with the number of self-reported injury history. Method: A total of 148 players (75 men, 73 women, 33.95 ± 9.87 years old) take part in this study, from whom 151 injuries were registered and classified regarding the type, location and injury situation (training or competition). A retrospective, descriptive study was set out, using an adapted version of a self-reported sports injury questionnaire. Chi-Squared, Residuals and Cramer’s V were calculated to study the strength of association between variables. Results: Findings revealed: i) overall predominance of muscle injuries in the lower limbs; ii) greater number of trunk injuries in men and upper limbs in women (p = 0.046); iii) higher rate of muscular lesions in players older than 35 years and tendinosis in younger than 35 years (p = 0.009); iv) higher rate of injuries in lower level players, especially in tendons and shoulder (p = 0.031). Conclusions: Muscular accounted for the majority of injuries in padel, particularly on the lower limbs. Males reported more trunk injuries, whilst females suffered more on the upper limbs. Players older than 35 years informed more muscular injuries; by contrast, tendinous injuries prevailed in younger than 35 years. Finally, the level of players revealed an inverse relationship in the number of injuries (the higher the level, the lower the injury rate).

A Prospective Study

Context: As the number of injuries in young soccer players increases, an epidemiological study is the first step in improving preventive strategies. Objectives: To analyze the injury profile of a Spanish professional soccer club’s academy during 4 consecutive seasons and to examine the injury incidence across different chronological age groups. Design: Prospective cohort design. Setting: Aggregate injury and exposure data collected during 4 consecutive seasons. Participants: Three hundred nine elite male young soccer players. Main Outcomes Measures: Injuries that led to participation time missed from training and match play prospectively reported by medical or coaching staff of the club. Results: A total of 464 time-loss injuries were observed during this study period. The overall injury incidence was 2.93 injuries per 1000 hours, with higher incidence during matches than during training (10.16 vs 2.10 injuries/1000 h; rate ratio [RR] = 0.21; 95% confidence interval [CI], 0.17–0.25; P < .05), with the U14 age group presenting the lowest injury rate (2.39 injuries/1000 h; RR = 1.15–1.57; P < .05). In terms of injury severity, moderate injuries were the most frequent (1.42 injuries/1000 h). Muscle injuries were the most common type of injuries (57.7%; 2.75 injuries/1000 h; RR = 1.84–13.4; P < .05), and hamstrings (93/268) were the most affected muscle group (0.58 injuries/1000 h; RR = 1.58–2.91; P < .05). Injury incidence showed a seasonal variation as indicated by peaks in August and October. In matches, specifically, the match period between 75 and 90 minutes showed the highest injury incidence (10.29 injuries/1000 h; RR = 1.89–6.38; P < .01). Conclusions: The findings of this study suggest that specific preventive strategies must be implemented to try to reduce the injury incidence in Spanish elite young soccer players attending to the characteristics of each age group.

The One of many way to connect to the database through the android application is using volleyball and RESTAPI. By using RestAPI, the android application does not directly connect to the database but there is an intermediary in the form of an API. In android development, Android-volley has the disadvantage of making requests from large and large data, so an evaluation is needed to test the capabilities of the Android volley. This research was conducted to test android-volley to retrieve data through RESTAPI presented in the form of an application to retrieve medicinal plant data. From the test results can be used by volley an error occurs when the back button is pressed, in this case another process is carried out if the previous volley has not been loaded. This error occurred on several android versions such as lollipops and marshmallows also on some brands of devices. So that in using android-volley developer need to check the request queue process that is carried out by the user, if the data retrieval process by volley has not been completed, it is necessary to stop the process to download data using volley so that there is no Android Not Responding (ANR) error.Keywords: Android, Volley, WP REST API, ANR Error

The paper deals with the organization and decisions of the conference of the Minister-Presidents of German lands in Munich on June 6-7, 1947, which became the one and only meeting of the heads of the state governments of the western and eastern occupation zones before the division of Germany. The conference was the first experience of national positioning of the regional elite and clearly demonstrated that by the middle of 1947, not only between the allies, but also among German politicians, the incompatibility of perspectives of further constitutional development was existent and all the basic conditions for the division of Germany became ripe. Munich was the last significant demonstration of this disunity and the moment of the final turn towards the three-zone orientation of the West German elite.

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.

This study aimed to investigate the moment carrying behavior of typical Tibetan timber beam-column joints under monotonic vertical static load and also evaluate the influence of length ratio of Gongmu to beam (LRGB) and dowels layout on the structural performance of the joint. Six full-scale specimens were fabricated with same construction but different Gongmu length and dowels position. The moment carrying performance of beam-column joints in terms of failure mode, moment resistance, and rotational stiffness of joints were obtained via monotonic loading tests. Test results indicated that all joints are characterized by compressive failure perpendicular to grain of Ludou. Additionally, it was found that greater LRGB leads to greater initial rotational stiffness and maximum moment of the joint by an increase of restraint length for beam end; however, offsetting dowels toward column resulted smaller stiffness and ultimate bending moment of joints, particularly, offsetting Beam-Gongmu dowels toward column changed the moment-rotation curve pattern of the beam-column joint, accompanied by a hardening stiffness at last phase. Furthermore, a simplified trilinear model was proposed to represent the moment-rotation relationship of the typical Tibetan timber beam-column joint.

After having studied in great detail the observational HR diagram (log Teff, Mbol) composed by 40 main sequence stars of the Hyades (Perryman et al.,1997, A&A., in press), we have tried to apply the same method to the observational main sequences of the three next nearest open clusters: Coma Berenices, the Pleiades, and Praesepe. This method consists in comparing the observational main sequence of the clusters with a grid of theoretical ZAMSs. The stars composing the observational main sequences had to have reliable absolute bolometric magnitudes, coming all from individual Hipparcos parallaxes, precise bolometric corrections, effective temperatures and metal abundances from high resolution detailed spectroscopic analyses. If we assume, following the work by Fernandez et al. (1996, A&A,311,127), that the mixing-lenth parameter is solar, the position of a theoretical ZAMS, in the (log Teff, Mbol) plane, computed with given input physics, only depends on two free parameters: the He content Y by mass, and the metallicity Z by mass. If effective temperature and metallicity of the constituting stars of the 4 clusters are previously known by means of detailed analyses, one can deduce their helium abundances by means of an appropriate grid of theoretical ZAMS’s. The comparison between the empirical (log Teff, Mbol) main sequence of the Hyades and the computed ZAMS corresponding to the observed metallicity Z of the Hyades (Z= 0.0240 ± 0.0085) gives a He abundance for the Hyades, Y= 0.26 ± 0.02. Our interpretation, concerning the observational position of the main sequence of the three nearest clusters after the Hyades, is still under way and appears to be greatly more difficult than for the Hyades. For the moment we can say that: ‒ The 15 dwarfs analysed in detailed in Coma have a solar metallicity: [Fe/H] = -0.05 ± 0.06. However, their observational main sequence fit better with the Hyades ZAMS. ‒ The mean metallicity of 13 Pleiades dwarfs analysed in detail is solar. A metal deficient and He normal ZAMS would fit better. But, a warning for absorption in the Pleiades has to be recalled. ‒ The upper main sequence of Praesepe, (the more distant cluster: 180 pc) composed by 11 stars, analysed in detail, is the one which has the best fit with the Hyades ZAMS. The deduced ‘turnoff age’ of the cluster is slightly higher than that of the Hyades: 0.8 Gyr instead of 0.63 Gyr.

BackgroundAcute muscle injuries in elite athletes are responsible for a large portion of time loss injuries.AimTo describe the frequency, the anatomic distribution, and severity of imaging-detected acute muscle injuries among athletes who competed in the Rio de Janeiro 2016 Summer Olympics.MethodsWe recorded all sports injuries reported by the National Olympic Committee medical teams and the Organising Committee medical staff during the 2016 Summer Olympics. Imaging of acute muscle injuries was performed at the IOC’s polyclinic within the Olympic Village using ultrasound and 3.0 T and 1.5 T MRI scanners. The assessment of images was performed centrally by three musculoskeletal radiologists. The distribution of injuries by anatomic location and sports discipline and the severity of injuries were recorded.ResultsIn total, 11 274 athletes from 207 teams were included. A total of 1101 injuries were reported. Central review of radiological images revealed 81 acute muscle injuries in 77 athletes (66% male, mean age: 25.4 years, range 18–38 years). Athletics (track and field) athletes were the most commonly affected (n=39, 48%), followed by football players (n=9, 11%). The majority of injuries affected muscles from lower limbs (n=68, 84%), with the hamstring being the most commonly involved. Most injuries were grade 2 injuries according to the Peetrons classification (n=44, 54%), and we found 18 injuries exhibiting intramuscular tendon involvement on MRI.ConclusionImaging-detected acute muscle injuries during the 2016 Summer Olympics affected mainly thigh muscles in athletics disciplines.

Squat exercise is acquiring interest in many fields, due to its benefits in improving health and its biomechanical similarities to a wide range of sport motions and the recruitment of many body segments in a single maneuver. Several researches had examined considerable biomechanical aspects of lower limbs during squat, but not without limitations. The main goal of this study focuses on the analysis of the foot contribution during a partial body weight squat, using a two-segment foot model that considers separately the forefoot and the hindfoot. The forefoot and hindfoot are articulated by the midtarsal joint. Five subjects performed a series of three trials, and results were averaged. Joint kinematics and dynamics were obtained using motion capture system, two force plates closed together, and inverse dynamics techniques. The midtarsal joint reached a dorsiflexion peak of 4°. Different strategies between subjects revealed 4° supination and 2.5° pronation of the forefoot. Vertical GRF showed 20% of body weight concentrated on the forefoot and 30% on the hindfoot. The percentages varied during motion, with a peak of 40% on the hindfoot and correspondently 10% on the forefoot, while the traditional model depicted the unique constant 50% value. Ankle peak of plantarflexion moment, power absorption, and power generation was consistent with values estimated by the one-segment model, without statistical significance.
