01Short answer

During leukaemia treatment people often move very little because of tiredness, hospital stays and infection risk. This leads to loss of muscle and stamina. After treatment, physical activity is one of the best-proven ways to reduce fatigue (topic “Chronic fatigue”), strengthen muscles and bones, protect the heart, maintain weight and improve mood and sleep. The general rule: start slowly and build up gradually. In the first days, 5–10 minutes of walking may be enough (topic “Walking”). Then slowly increase the time and pace. The WHO and ACS recommend that adults do at least 150 minutes of moderate activity a week (such as brisk walking) and strength exercises twice a week (topic “Rebuilding strength”); children should average 60 minutes of active movement a day. This is the end goal — it is normal to reach it over weeks and months. Any activity is better than none. Balancing tiredness and rest matters (topic “Balancing fatigue and activity”). If you have heart, lung or bone problems, neuropathy or balance difficulties, a physiotherapist or rehabilitation specialist can help build a safe programme (topics “Rehabilitation” and “Physiotherapy”).

02Simple explanation

Activity reduces fatigue and improves strength and mood.

The rule: start slowly, build up gradually.

The goal: 150 minutes a week and 2 strength sessions.

Any activity is better than none.

If you have problems: a physiotherapist.

03Scientific explanation

Recommendations: the WHO recommends that adults do 150–300 minutes of moderate or 75–150 minutes of vigorous activity a week, plus strength exercises on at least 2 days; children and teenagers should average 60 minutes a day.

Survivors: the ACS recommends that survivors return to normal activity as soon as possible after treatment and avoid long periods of sitting.

Benefits: the ACS and WCRF note that physical activity reduces fatigue, anxiety and depression and improves quality of life and physical strength.

Safety: the COG recommends that survivors with heart, lung or bone late effects talk to their doctor before starting a new intensive sport.

04What happens in the body?

Why be active?

Activity strengthens muscles, bones and the heart, reduces fatigue, and improves sleep and mood.

When can I start?

Often straight after treatment ends, with light activity. Ask your doctor about timing and any limits.

How do I start?

Begin with 5–10 minutes of walking a day. Add a few minutes each week. A pace at which you can talk but not sing is moderate intensity.

Strength and flexibility

Add gentle strength exercises twice a week (using your body weight or a resistance band) and stretching. A physiotherapist can teach good technique.

Children

Play, cycling, swimming and dancing — the best activity for a child is the one they enjoy. Agree the return to school sport with the doctor.

When to call your doctor

Worrying signs — fever, bleeding, new pain, breathlessness — should be reported to your doctor between visits too. Getting in touch early is always better than waiting.
