We present and validate a test able to provide reliable body sway measurements in air pistol shooting, without the use of a gun. 46 senior male pistol shooters who participated in Spanish air pistol championships participated in the study. Body sway data of two static bipodal balance tests have been compared: during the first test, shooting was simulated by use of a dumbbell, while during the second test the shooters own pistol was used. Both tests were performed the day previous to the competition, during the official training time and at the training stands to simulate competition conditions. The participantś performance was determined as the total score of 60 shots at competition. Apart from the commonly used variables that refer to movements of the shooters centre of pressure (COP), such as COP displacements on the X and Y axes, maximum and average COP velocities and total COP area, the present analysis also included variables that provide information regarding the axes of the COP ellipse (length and angle in respect to X). A strong statistically significant correlation between the two tests was found (with an interclass correlation varying between 0.59 and 0.92). A statistically significant inverse linear correlation was also found between performance and COP movements. The study concludes that dumbbell tests are perfectly valid for measuring body sway by simulating pistol shooting.
Actualmente se prepara una nueva Ley para la economía social en España, y en un entorno de crisis económica global es momento de reflexionar sobre las fuentes de financiación existentes en este sector así como sobre su correcta utilización. El objetivo de este artículo es demostrar no solo la necesidad urgente de dicha Ley, sino de que la misma recoja con claridad las fuentes de financiación a las que puede acudir una entidad englobada en la parcela de la economía social, concienciando de la importancia de poseer una información adecuada sobre ellas, pues de esa información dependerá, en ocasiones, su propia subsistencia. La metodología empleada consiste en un análisis de las normas existentes así como de las fuentes de financiación recogidas en ellas. El análisis de los resultados muestra que la actual normativa es deficiente y constituye un lastre para el desarrollo de la economía en España. Como conclusión principal destaca la necesidad de que la nueva Ley, en apariencia bastante próxima, recoja con detalle todas las posibles formas de financiación, a sabiendas de que la dinámica de la economía impondrá la necesidad de reformarla o añadir nuevos apartados muy pronto.
