Caracterización de la marcha humana bajo la influencia de calzado industrial: caso de estudio en inspectores de revisión técnico mecánica

Abstract

The purpose of this case study was to analyze the impact of the use of industrial safety footwear on inspectors of an automotive diagnostic center, through a process of characterizing the progress of a sample of five (5) men using industrial footwear, according to your routine at your workplace. The result of the investigation allowed to assess the level of fatigue in relation to the number of steps performed by the subjects at the end of the workday, establishing an average of 9,205.4 (400.68) steps and a level of fatigue of (2.8) (1.16). There were significant differences in four (4) spatio-temporal parameters, with probability P <0.05. In two (2) subjects of the sample, there was no influence of industrial footwear, P> 0.05. Industrial safety footwear has an impact on workers due to poor ventilation, generating excess sweat on the feet. The rigidity of the footwear and the difficulty to drive, are some of the disadvantages that prevail in the sample. The prolonged use of this footwear causes an average level of fatigue among the workers at the end of the working day. The subjects who registered differences using industrial footwear and frequent footwear, compared intrasubject show a decrease in the length of the step, the length of the stride, cadence of the step and speed of the march with the parameters established in previous investigations.
