While this may be the case, we do see that poor workload management can be one of many major contributing factors that may lead to one experiencing injury. One big question was how many telephone operators were necessary to run the switchboard. Automated central offices hadn’t yet been invented, so human operators were required to establish connections for callers. introduced the concept of the acute:chronic workload ratio (ACWR) with acute workload hypothetically representing the fatigue component and chronic workload the fitness component of Banister's model (Figure 1).

H., Marques, A. R., & Blanch, P. (2020). Acute:Chronic Workload Ratio: Conceptual Issues and Fundamental Pitfalls. Acute:Chronic Workload Ratio: Conceptual Issues and Fundamental Pitfalls. Methods Agent-based modelling (ABM) was used to model the occurrence of sports injury in a synthetic athlete population. Background The acute:chronic workload ratio (ACWR) is commonly used to manage training load in sports, particularly to reduce injury risk. The main goal was to provide a tool to assess load dynamics that incorporates load orientation and weekly density (frequency normalized) in addition to proxies of volume and external/internal load. A discussion with exercise scientist and conditioning coach Dr Jason Tee on the acute:chronic workload paradigm. Dr Jason Tee is a sports coach and scientist with broad experience in the areas of talent development, injury prevention and coach education.

In recent years, TL-injury research has grown exponentially, particularly after 2 publications 6,7 and subsequent editorials 8,9 that contributed to catalyzing the interest in this area. He also states that the operator's physiology, a reflection of bodily functions, is further removed from operator-system performance than, e.g., primary-task performance. Jason’s approach is to combine … The ABM was developed based on sports injury causal frameworks and was applied in the context of distance running-related injury (RRI).
