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

9 de novembro de 2026 atualizado por: University of Erlangen-Nürnberg Medical School

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.
