Feasibility of a progressive protocol of high-intensity interval training for overweight/obese, sedentary African American women: a retrospective analysis

ConclusionAlbeit based on a limited number of participants, we found an attrition rate that was higher than what has been reported previously for HIIT (~  17.6%) when previously-sedentary overweight/obese AA women performed a protocol with work-interval intensity progressed from 75 to 90% HRR during a 14-week intervention. With respect to intensity, the precipitous drop for achievement of the target HR during the fourth stage (weeks 8–14) for tho se who did complete the protocol implies that it might be advisable to restrict work-interval intensity to<  90% HRR.Trial registrationClinicalTrials.gov.
