Background
High quality evidence supports the integration of exercise to mitigate treatment- related side effects in a wide range of paediatric and adult cancer cohorts. However, the implementation of exercise in adolescent and young adult (AYA) cancer patients is yet to be explored in depth. FiGHTINGF!T is a randomised controlled cross over trial designed to determine if a supervised, structured and progressive exercise program can reduce the decline in physical fitness (V02peak) associated with cancer treatment in AYAs from diagnosis.
Methods/Design
A total of 40 AYAs recently diagnosed and due to commence systemic treatment (± 2 weeks) for a primary haematological malignancy or solid tumour will be recruited and randomised to either an immediate exercise intervention or usual care (delayed exercise) for 10 weeks. This randomised controlled crossover trial will see both groups engage in a supervised exercise intervention from either diagnosis (baseline assessment) for 10 weeks (0-10 weeks) or following an interim assessment to 20 weeks (10-20 weeks). The bi-weekly tailored exercise program will combine aerobic and resistance exercises and be supervised by an Accredited Exercise Physiologist. Participants will complete a range of assessments at 0, 10 and 20 weeks including cardiopulmonary exercise tests, 1 repetition maximum strength measures, physical functioning and self-reported quality of life measurements. Patient reported treatment-related toxicities will be recorded on a weekly basis.
Discussion
The FiGHTINGF!T trial will provide insight into the potential benefits of a supervised exercise program in AYAs undergoing cancer treatment. This trial will contribute to the evidence supporting the necessary integration of exercise during cancer treatment, specifically in the under-reported AYA cohort.
