Análisis de la fatiga neuromuscular después de distintas series de juegos reducidos en jugadores de baloncesto en silla de ruedas
Get PDF28 p. -- Bibliogr.: p. 18-22El objetivo del presente estudio fue analizar las diferencias entre jugadores con (SCI) y sin (No SCI) lesión medular en la respuesta fisiológica y en la fatiga neuromuscular en las diferentes series de un juego reducido (SSG) en baloncesto en silla de ruedas (BSR). Trece jugadores de BSR de alto nivel realizaron una vez por semana una sesión de SSG de 5 vs. 5 jugadores durante 5 semanas consecutivas. Se registraron la FC absoluta y relativa durante los SSG y la percepción del esfuerzo, la temperatura timpánica y la capacidad de aceleración (5 m, 20 m y 5-20 m) al finalizar cada serie de SSG. No se observaron diferencias significativas entre jugadores SCI y No SCI en las variables de FC relativas, mientras que en las variables absolutas el grupo SCI mostró valores más bajos. Con respecto a la evolución de la respuesta fisiológica, el grupo SCI no mostró diferencias entre series, mientras que el grupo No SCI mostro un aumento en las variables de FC absolutas y relativas y de percepción del esfuerzo. Por otro lado, el grupo SCI mostró una pérdida de la capacidad de esprint entre series, mientras que el grupo No SCI no mostro ninguna variación. Sin embargo, el grupo SCI declaró valores más altos de RPEmusTL. Los resultados del presente estudio ponen de manifiesto la necesidad de que los entrenadores consideren el que los jugadores tengan o no SCI a la hora de planificar y modular las cargas del entrenamiento y recuperación
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Condición física y ansiedad competitiva en jugadores amateur de pádel
No full textThe aim of this study was to analyze differences in physical fitness and competitive anxiety among amateur padel players based on their age, skill level, court position, and training frequency. Fifty-four male amateur players (35.6 ± 11.4 years) participated in the study. The observed results included a vertical jump, grip strength, a 5-meter acceleration, and a CODA test. Cognitive and somatic anxiety levels were moderate, while self-confidence was relatively high (3.3 ± 0.5 points). Significant differences were observed in physical fitness based on age and court position, and in competitive anxiety based on age, court position, and training frequency. Younger players showed superior vertical jump and change-of-direction performance, while skill level had no significant effect. In conclusion, age and court position appear to influence players' physical and psychological capabilities, highlighting both as key factors in the design of training strategies.El objetivo de este estudio fue analizar las diferencias en la condición física y la ansiedad competitiva entre jugadores amateur de pádel en función de su edad, nivel de juego, posición en la pista y frecuencia de entrenamiento. En el estudio participaron cincuenta y cuatro jugadores amateur varones (35,6 ± 11,4 años). Las variables analizadas incluyeron el salto vertical, la fuerza de prensión manual, la aceleración en 5 metros y una prueba de cambio de dirección (CCD). Los niveles de ansiedad cognitiva y somática fueron moderados, mientras que la autoconfianza fue relativamente alta (3,3 ± 0,5 puntos). Se observaron diferencias significativas en la condición física en función de la edad y la posición en la pista, y en la ansiedad competitiva según la edad, la posición y la frecuencia de entrenamiento. Los jugadores más jóvenes mostraron un mejor rendimiento en el salto vertical y en el cambio de dirección, mientras que el nivel de juego no tuvo un efecto significativo. En conclusión, la edad y la posición en la pista parecen influir en las capacidades físicas y psicológicas de los jugadores, lo que resalta la importancia de ambos factores en el diseño de estrategias de entrenamiento.
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Physical Activity Practice And Health Perception Of Physically Active People With Disabilities
No full textObjective: The aim of this study was to analyze the level of physical activity (PA) and the perception of health in people with disabilities, as well as to identify possible differences according to sex. Method: 52 people with disabilities (32 women and 20 men) participated and the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) and the SF-36 questionnaires were used to analyze the level of practice and the perception of health, respectively. Results: The results show that the participants have an adequate level of PA practice and a moderate perception of health. Regarding gender differences, no significant differences were found in terms of level of PA practice, however men showed a better health perception than women in several of the items (p < 0.05). Conclusions: The present study shows that those people immersed in a physical activity program or who do some kind of sport reach the recommended levels of PA practice, without finding significant differences between men and womenObjetivo: Este estudo tem como objetivo analisar o nível de prática de atividade física (AF) e a percepção de saúde em pessoas com deficiência, além de identificar possíveis diferenças em função do sexo.
