El coeficiente de correlación de Pearson (r) entre la fuerza de agarre y la antropometría del antebrazo manual supone una relación existente o no lineal entre ellos. La recopilación de datos de las variables se obtuvo de diez adultos jóvenes, tanto en el antebrazo derecho como en el izquierdo, se tuvieron en cuenta algunas variables cualitativas: ser diestro, el género con cinco (5) hombres y cinco (5) mujeres, y se establecieron como condiciones que el individuo estaba sano y no tenía una carrera previa como atleta. Se concluye una relación lineal directa con la antropometría de la mano y la fuerza de agarre, aunque como se esperaba, existía una gran diferencia entre la fuerza ejercida por un individuo masculino y femenino, siendo la primera más fuerte. Respecto al antebrazo, se encontró una relación inversa entre la circunferencia máxima del antebrazo y la fuerza de agarre. Finalmente, las relaciones más fuertes encontradas fueron en el ancho y largo de la palma, así como en la circunferencia de la muñeca. Los resultados se validaron comparando los resultados de esta investigación con los resultados de literaturas especializadas. Algunas consideraciones pueden ser consideradas para futuras investigaciones. La fuerza de agarre puede promover el riesgo de accidentes y los ergónomos deben considerar este factor de manera adecuada para su diseño.

As a cultural creation, the face has a long history. Our relationship with the face is through its images: Mirrors, reflections, photographs, visions. The experience about the face deserves a genealogy, a careful attention because it is the product of a cultural construction that establishes the social status granted to the person. Different mediums of the image persisted in making faces visible or recognizable. The anthropometry of the 19th century established a new relationship between the face and the Self. Photography allowed us to explore, measure and classify the images of the face and of the human being. This explains the fascination with photography in Bertillon and Darwin. At the same time, the arrival of photography also opened the way to the era of the democratization of the face. But the images of faces that we will approach in this article are images produced by techniques of reconstruction and facial recognition based on biometric and genetic data. Biometrics seeks to recognize individuals through physical and behavioral traits, articulating an image technique with mathematical techniques. Even portraits have become instruments for surveillance. This responds to the conditioning of an apparatus that captures and determines behaviors and discourses. As Giorgio Agamben argues, certain apparatus have imposed themselves as spatial optical articulations, but also epistemic, political and ideological, capable of assuming a specific conception of the vision and position of the subject in front of the world. We define the face as an apparatus. If the history of the portrait pictures theory, as proposed by W. f. T. Mitchell, in relation to the history of the development of the process of individuation of the self, genetic biometrics dissolves it completely, since it is not a measure of the human but its negation.

This study aims to find out to determine the anthropometric factors and dominant physical conditions in the ability to play female futsal. The population of this research is 14 female futsal teams at IAIN Purwokerto. This type of research is quantitative, using a Confirmatory Factor Analysis design. The data collection technique used in this study was by test and measurement. Data from the test results and measurements are then processed and calculated using the KMO and Bartlett's Test program. The results of the study obtained anthropometric factors that were dominantly influential in determining the performance of futsal athletes, namely the ratio of leg length and height. Factors of physical condition that are dominantly influential in determining the performance of futsal athletes are agility.

Objective: We evaluated the current use and fit of structural firefighting gloves and developed an improved sizing scheme that better accommodates the U.S. firefighter population. Background: Among surveys, 24% to 30% of men and 31% to 62% of women reported experiencing problems with the fit or bulkiness of their structural firefighting gloves. Method: An age-, race/ethnicity-, and gender-stratified sample of 863 male and 88 female firefighters across the United States participated in the study. Fourteen hand dimensions relevant to glove design were measured. A cluster analysis of the hand dimensions was performed to explore options for an improved sizing scheme. Results: The current national standard structural firefighting glove-sizing scheme underrepresents firefighter hand size range and shape variation. In addition, mismatch between existing sizing specifications and hand characteristics, such as hand dimensions, user selection of glove size, and the existing glove sizing specifications, is significant. An improved glove-sizing plan based on clusters of overall hand size and hand/finger breadth-to-length contrast has been developed. Conclusion: This study presents the most up-to-date firefighter hand anthropometry and a new perspective on glove accommodation. The new seven-size system contains narrower variations (standard deviations) for almost all dimensions for each glove size than the current sizing practices. Application: The proposed science-based sizing plan for structural firefighting gloves provides a step-forward perspective (i.e., including two women hand model–based sizes and two wide-palm sizes for men) for glove manufacturers to advance firefighter hand protection.
