Reliability of simulated combat tasks performed by Brazilian Air Force cadets.
The Brazilian Air Force (BAF) has developed physical evaluations focused on the demands required in combat scenarios, giving rise to the Simulated Tasks (STs). Therefore, the purpose of the present study was to determine test-retest reliability and investigate learning effects of the five STs established among the BAF. Fifty-six subjects performed five STs three times, after completing a previous familiarisation session. Repeated measures analysis of variance (ANOVA) was used to determine the occurrence of learning effects, and the intraclass correlation coefficient (ICC) was used to identify the reliability of each ST. ANOVA revealed no significant differences in the subject's scores across trials for all the STs, and the ICCs ranged from 0.75 to 0.92 (p < 0.01). In conclusion, this study identified that the five STs showed no learning effects across three successive trials and exhibited high levels of reliability.
期刊介绍：
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
