Investigating the Relationship Between Objective and Subjective Measures of Physical Demand During Passive Exoskeleton Use
… the feasibility of using subjective measures of physical demand in place of costly and less practical objective measures. Normalized electromyography (nEMG) data and ratings of perceived exertion (RPE) were collected from seven different studies conducted by the Occupational Ergonomics and …

Assessing Soccer Referee Performance Using Work Sample and Conventional Testing Methods
… event interview (BEI), a written test, and a physical performance test battery were compared for testing college soccer referees as linesmen. A content-oriented strategy (Alba & Dickinson, 1985) was used to prepare the tests. Sixty-one referees from two testing sites were assigned to one of …

Interactive Effects of Physical and Mental Workload: A Study of Muscle Function, Capacity and Exertion Type
Workers experience combined physical and mental demands in their daily jobs, yet the contribution of these concurrent demands in the development of work-related musculoskeletal disorders (WMSDs) is not clearly understood. There is a need to understand how concurrent demands interact with different …

A Quasi-Experimental Approach for Assessing Air Traffic Controller Workload
… (CHI) and its effect on the cognitive effort and physical task requirements imposed on the controller. The various workload methodologies and techniques were reviewed for specific workload techniques applicable to the operational environment when resources, such as time and funding, are lacking …

The Effectiveness of Biopsychosocial Interventions at the Dallas Spinal Rehabilitation Center: Applying the NIDRR Logic Model
… long-term efficacy, risk of addiction, and the physical and psychological side effects of these medications continue to be heavily debated. There is strong evidence to support a biopsychosocial treatment approach for chronic pain which reduces narcotic dependence and restores daily functioning. …

The Physical and Physiological Demands of Taekwondo Training and International Competition
… aim of this PhD thesis was to characterise the physical and physiological demands of taekwondo in the aftermath of an evolution of rule changes over the last 19 years. The entry of taekwondo to the Olympic games in 2000 brought a spotlight and visibility to the sport that put pressure on the …

Multiple Autonomous Vehicle Extended Reality Immersive Control Systems: A Conceptual Exploration & Empirical Evaluation
… these strengths, limitations such as increased physical demand, ergonomic discomfort, and precise waypoint placement challenges were noted, indicating the need for iterative design improvements. Some participant feedback also indicated that cross-reality GCS interfaces could be valuable to …

Effects of Increases in Mental Workload on Avoidance of Ground Hazards
… increased in variability. Subjective ratings of physical demand and effort obtained across the three levels of mental workload increased significantly, along with perceptions of workload associated with a perceived decline in performance. Subjective ratings obtained across the two levels of …
