Avaliação da carga mental de trabalho e da necessidade de descanso em pedreiros do Vale do Jaguaribe utilizando os instrumentos NASA-TLX E ENEDE

Abstract

This study analyzed the mental load and need for rest of bricklayers in Vale do Jaguaribe using NASA-TLX and ENEDE. An analysis revealed that all workers face symptoms of fatigue and a high need for rest. The NASA-TLX results showed high levels of workload, with a predominance of physical demand and significant mental load, with averages between 11 and 12 points. Physical demand and effort were high in all locations, while mental demand and frustration levels varied between Limoeiro do Norte, Jaguaruana and Palhano. ENEDE confirmed a high need for rest, with rates above 45%, highlighting concerns about well-being and occupational health. Influencing factors included the use of heavy equipment, intense physical exertion, adverse conditions such as heat and noise, and lack of infrastructure for breaks.
