ESTUDIO TERMOGRAFÍCO EN ÁREAS DEL BRAZO EN MUJERES AL REALIZAR TAREAS REPETITIVAS SIN FUERZA (THERMOGRAPHIC STUDY IN AREAS OF THE ARM IN WOMEN PERFORMING REPETITIVE TASKS WITHOUT STRENGTH)
Resumen
El presente trabajo identifica por medio de la termografía la respuesta musculo esquelético de distintas zonas del brazo de cinco operarias al realizar el ensamble de un conector eléctrico en una estación de trabajo experimental. Las operarias realizaron el ensamble a dos ritmos de trabajo. La metodología empleada consideró los siguientes puntos: 1) Toma de temperaturas a operarias en las zonas del brazo antes y después de la tarea. 2) Determinación de los cambios térmicos en las distintas zonas del brazo. 3) Identificación de las zonas con mayor respuesta musculoesquelético y 4) Generación de resultados y conclusiones. Se determinó que a ritmo normal tuvo mayor impacto en el codo, antebrazo y hombro, y menor en mano y brazo. En el ritmo acelerado el impacto fue mayor en mano, codo y hombro, menor antebrazo y brazo. Se concluye que todas las medias de las deltas de temperaturas son diferentes por el tipo de actividad, condición físicas y edad de las evaluadas.

Abstract
The present work identifies by means of thermography the skeletal muscle response of different areas of the arm of five female workers when making the assembly of an electrical connector in an experimental work station. The operators carried out the assembly at two work rhythms. The methodology used considered the following points: 1) Taking temperatures of operators in the areas of the arm before and after the task 2) Determination of the thermal changes in the different areas of the arm 3) Identification of the areas with the greatest musculoskeletal response and 4) Generation of results and conclusions. It was determined that at normal rhythm it had a greater impact on the elbow, forearm and shoulder, and less on the hand and arm. In the accelerated rhythm, the impact was greater in the hand, elbow and shoulder, lower forearm and arm. It is concluded that all the means of the temperature deltas are different due to the type of activity, physical condition and age of those evaluated.
Keywords: Arm, Repetitive Assembly, Tasks, Thermography.
