Millions of people with osteoporosis should not be afraid to exercise, as experts have said in guidance aimed at boosting bone health, cutting the risk of falls and improving posture.
More than 3 million people in the UK are affected by the condition, which weakens bones and makes them more likely to break.
A broken wrist, hip, and spine are the most common injuries. More than half a million people are treated for osteoporosis on the National Health Service every year.
UK guidance on exercise and osteoporosis has been absent. There are some in the US, Australia, and Canada.
It's important that people with osteoporosis don't miss out on regular exercise because it strengthens bones, reduces the risk of falls and improves posture.
Uncertainties about what type of physical activity is safe, particularly later in life or when bones have weakened, have left doctors unsure what to recommend and deterred some patients from regular activity.
In order to clear up the confusion, a multidisciplinary panel of experts reviewed existing evidence and drew on clinical and patient opinion to come up with recommendations to maximize bone health.
The British Journal of Sports Medicine published the consensus statement endorsed by the Royal Osteoporosis Society.
It says that people with the condition should be encouraged to do more by doing an exercise routine that focuses on muscle strengthening on two to three days a week and brief bursts of moderate-impact activities, such as jogging, aerobics or Zumba on most days.
The advice is to include lower-impact exercise up to the level of brisk walking for 20 minutes a day for those who have previously sustained a vertebral fracture.
Anyone who is new to regular physical activity, worried about their technique or unsure how to build their fitness can seek advice from any trained exercise instructor, according to the chair of the panel. Those with a history of falls can contact their local falls service.
