Nonresponse to exercise has been extensively examined in young athletes but is seldom reported in studies of aerobic exercise interventions in older adults. This study examined the prevalence of nonresponse and poor response to exercise in functional and quality of life outcomes and response patterns between and among older adults undergoing 12-weeks of supervised exercise therapy for the management of peripheral artery disease (N = 44, mean age 72.3 years, 47.7% female). The prevalence of nonresponse (no change/decline in performance) in walking distance was 31.8%. The prevalence of poor response (lack of a clinically meaningful improvement) was 43.2%. Similar patterns of response were observed in both objective and patient-reported measures of physical function. All participants improved in at least one outcome; only two participants improved in all measured outcomes. Additional research should examine modifiable predictors of response to inform programming and maximize an individual’s potential benefit from exercise therapy.
