Optimizing Recovery in Pediatric ALL Survivors: A Training Comparison

This study compared the effects of constant-load aerobic exercise (CL-AEx) and graded aerobic exercise (G-AEx) on cardiopulmonary fitness and functional capacity in pediatric survivors of acute lymphoblastic leukemia (ALL). A cohort of 72 pediatric ALL survivors was randomly assigned to one of three groups: a CL-AEx group (n=24), a G-AEx group (n=24), or a control group (n=24). All groups participated in a structured exercise regimen. The CL-AEx group performed additional moderate-intensity aerobic training at a fixed load, while the G-AEx group performed additional aerobic training with progressive increases in intensity and duration. The control group performed the structured exercise regimen only. Interventions were administered three times per week for 12 consecutive weeks. Cardiopulmonary fitness and functional capacity were assessed in all three groups at baseline and following the completion of the 12-week intervention.
