attention to the physical and physiological needs of a soccer referee plays an important role in his performance in a match as in order to regulate the rules of the game, the referee should track the event and players by moving inside the pitch continually with no restriction. the aim of this research was to study the variations in workload, heart rate and blood lactate in elite soccer referees...

The performance of any system cannot be determined without knowing the workload, that is, the set of requests presented to the system. Workload characterization is the process by which we produce models that are capable of describing and reproducing the behavior of a workload. Such models are imperative to any performance related studies such as capacity planning, workload balancing, performanc...

In this paper we test the hypothesis that organizational structure, and the history of that structure, influences mutual workload awareness. More specifically, we explored the congruence of workload awareness among a number of decision makers acting in two organizational structures (functional vs. divisional) with different histories (divisional followed by functional vs. functional followed by...

The role of humans in aviation and other domains continues to shift from manual control to automation monitoring. Studies have found that humans are often poorly suited for monitoring roles, and workload can easily spike in offnominal situations. Current workload measurement tools, like NASA TLX, use human operators to assess their own workload after using a prototype system. Such measures are ...

Complex traffic situations and high driving workload are the leading contributing factors to traffic crashes. There is a strong correlation between driving performance and driving workload, such as visual workload from traffic signs on highway off-ramps. This study aimed to evaluate traffic safety by analyzing drivers' behavior and performance under the cognitive workload in complex environment...
