Fatigue is the state of being tired or inability to maintain an expected force. Fatigability is a measure of how fast someone gets tired and defined as susceptibility to fatigue a tendency to get tired or lose strength. Research shows that normal aging in older adults is associated with increased performance fatigability including loss of muscle, reduced endurance, worsened typical gait pattern, deteriorated typical healthy walking strides, and reduced maximal oxygen capacity compared to younger adults. Increased performance fatigability often leads to increased perceived fatigability that is associated with increased mental cost of completing normal activities of daily living. Assessing perceived and performance fatigability becomes useful when evaluating older adult healthiness because it shows potential early onset of chronic disease states with normal aging. Research shows performance fatigability is related to morbidity, mortality, hospitalizations, slower gait speed, worse six-minute walk distance, and functional decline in older adults. Veterans at VA Pittsburgh Gerofit health promotion program often report tiredness and fatigue that interfere with activities of daily living such as work-related duties, grocery shopping, yard and house work. Presented here is a needs assessment of Veterans perceived and performance fatigability with implications for Gerofit program future inquiry and practice to better address Veterans health concerns.
