Análise da diminuição de forças de aderência na mão por se uso de luva em atividades de limpeza e cafetaria

The literature reports studies related to grip strength decrease due to gloves in risk activities such as aviation or electricity maintenance. However, this factor has not been studied in cleaning tasks where the use of gloves is needed. Objectives: therefore, the need arises for measuring the strength which may be lost by the use of gloves and its implications in the performance of duties in different positions, in a population characterized by their vulnerability and muskulosqueletal injuries. Materials and methods: a 2x3 experimental design was made with two independent variables: the position into three different levels (neutral position, leaning on elbow and keeping forearm extended) and the use / not use of gloves so that the dependent variable was the grip strength. The experiment was made among 11 women who belonged to the cleaning and cafeteria area in a services company. Results: the glove factor exerts meaningful effect over grip strength with a significance level of 0.000. In addition, the decrease of the grip strength fluctuates from 18 % to 54 % according to the position of the measuring. Conclusions: the relation between the strength developed the nature of the task and the use of gloves produces suggestions to future researches such as, materials, strength detail measuring, and design of tools between others.
