When a child is diagnosed with acute leukaemia—the most common childhood cancer—parents understandably focus on chemotherapy and medical treatment. But researchers who reviewed 18 rigorous studies in Frontiers in Pediatrics found that what happens alongside treatment is equally important: structured exercise significantly improves recovery outcomes.
The problem is real. Intensive chemotherapy weakens children's bones, depletes their strength, causes severe fatigue, and can affect heart and lung fitness—effects that often persist long after treatment ends. This is where supervised movement becomes transformative.
Exercise rebuilds what chemotherapy breaks down
Children who follow structured exercise programmes during and after leukaemia treatment show measurable improvements in bone density (critical since chemotherapy makes bones fragile), cardiovascular and lung fitness, and overall quality of life. Many experience less fatigue and better emotional wellbeing. These aren't minor benefits—they're foundational for recovery.
One-size-fits-all won't work
The research emphasises that every child's exercise programme must be personalised. A paediatric oncology physiotherapist should assess your child's specific treatment phase and capabilities, then design a programme tailored for them. Equally important: timing matters. The same exercise won't suit intensive chemotherapy as it does during maintenance or after treatment ends. Programmes need continuous adjustment as your child progresses through different phases.
Games work better than clinical exercise
The studies show that game-based, play-focused activities significantly improve how well children stick with exercise programmes. Movement designed as a game or play activity—rather than formal "exercise"—keeps children engaged and motivated without feeling like clinical work.
Three steps to get your child moving
- Ask your medical team about physiotherapy and supervised exercise from day one of treatment, not as an afterthought.
- Request an assessment by a physiotherapist experienced in paediatric oncology to design a personalised programme for your child's specific needs.
- Work with your team to ensure the programme adjusts as your child moves through different treatment phases and recovery stages.
