The Rodgers Muscle Fatigue Analysis was proposed as a method to assess fatigue accumulation in muscles during various work patterns over 5 minutes. It hypothesizes that rapidly fatiguing muscles are more susceptible to injury. The method evaluates tasks performed for over an hour that involve awkward postures or frequent exertions to determine the risk of fatigue accumulation and priority for change. It involves rating effort levels, continuous effort duration, and effort frequency for different body regions to determine a priority for change from low to very high.
