HIIT-based Exercise Intervention for Improvement of Immunomodulatory, Cardiopulmonary, and Psychosocial Parameters During Maintenance Therapy of Paediatric Acute Lymphoblastic Leukaemia (HEALL) (HEALL)

In this study, the investigators aim to examine the effects of high-intensity interval training (HIIT) on cardiopulmonary fitness and immunological recovery in female ALL survivors who underwent cancer treatment during childhood and adolescence.
