This study used participants of the Exercise and Quality of Life in Leukemia Adults (EQUAL) randomized, controlled trial at the University of North Carolina Lineberger Comprehensive Cancer Center (Bryant et al., 2017). Participants in the exercise intervention arm (n = 9) were approached for an interview for this study. Inclusion criteria for participants on the EQUAL trial consisted of (a) being an adult aged 21 years or older, (b) being newly diagnosed with AML or ALL, (c) receiving induction therapy to begin chemotherapy with an expected hospital stay of 3–4 weeks, and (d) being able to speak and understand English. Exclusion criteria included cardiovascular disease; acute or chronic respiratory disease; acute or chronic bone, muscle, or joint abnormalities; altered mental state, dementia, or any other psychological condition that would prevent understanding of informed consent; another active malignancy; and active bleeding, acute thrombosis, ischemia, hemodynamic instability, or uncontrolled pain. Reasons for the low number of participants in the EQUAL study is related to the exploratory aim focused on cardiopulmonary exercise testing (CPET) in the acute leukemia population undergoing treatment. Participants with acute or chronic cardiovascular, respiratory, or bone conditions were excluded from the study because it was contraindicated in CPET; 39% of potential eligible participants were excluded because they had one of these comorbidities.
