RESUMO

The agricultural work is considered one of the most stressful since it demands elevated efforts The operation of agricultural machinery formulates a petition of the worker long hours in the same position, executing repetitive movements This fact leads to the fatigue compromising the health of the operator The work of the operator of agricultural machinery is carried out in the cabin being that this one very often presents problems ergonÃmicos what together with the physical conditions inapropriadas of the operator compromise again still more the efficiency of the work and his health In this context the objective of the work carried out the diagnosis biomecÃnico ergonÃmico and physiologic preliminary of operators of agricultural machinery of the Federal University of Plowing and also he valued if the machines used by them present the characteristics ergonÃmicas appropriate For each operator there were collected the data referring to the blood pressure the VO2mÃx the rate of physical mass (IMC)the reason waist / hip (RCQ) the stature the mass the percentage of fat and the measures antropomÃtricas basic There were done tests of flexibility of manual prehension and the test of horizontal impulse In the tractors there were collected the measures of distance of the seat driving of the seat to the pedal from the seat to the platform and of the base of the seat There were obtained also the levels of noise given out by the machines From the physiologic point of view the operators presented on the whole good results as for the IMC percentage of fat and blood pressure However they all presented low physical capacity Strong correlation was observed also one between the IMC and the RCQ Regarding the biomechanics the operators presented very weak results for the strength of inferior and superior members As for the flexibility a regular result happened considering to activity carried out by the workers Ergonomicamente the tractors presented acceptable values for the standards antropomÃtricos of the operators to the exception for the distance of the seat up to the platform which needs corrections The level of noise of the machines was left above the recommended one for work without the equipment of individual protection (EPI) Being so his use becomes compulsory the time of exhibition allowed for all the machines is inferior to the workload of daily work
