The Effect of Different Road Types on Timber Truck Drivers by Assessing the Load Environment of Drivers by Monitoring Changes in Muscle Tension

Our research aimed to quantify stress load in drivers by monitoring the on radial extensor carpi radialis (musculus radialis) different types of forest and other categories roads. We observed changes electrical potential skeletal muscles using electromyographic measurements heart rate a Biofeedback2000 x-pert recorder. measured loading during normal operation timber trucks with trailers, while reference took place passenger car. obtained descriptive statistics from individual evaluated normality data. Differences muscle increased when driving lower-grade The significantly, especially passing through villages, inversely proportional width roads radius their bends. Experiments revealed that loaded vehicles who drove were under higher stress. Muscle truck trailer was more difficult lower grades than grade I 41.3%. Driving is 21.9% For preventive health safety reasons, it optimal alternate trucking type work, thus minimizing chance occurrence disabilities.
