Too much exercise can cause stomach problems or blood poisoning, a study found.
People who exercise vigorously for more than two hours put themselves at risk of gut damage, research showed.
Running and exercising in hot weather increases the risk, researchers said.

The research, by Monash University in Australia said that ‘with increasing intensity and duration of exercise there was a proportional increased risk of gut damage and impaired gut function.’
The authors reviewed findings in a host of studies looking at the effects of excess exercise on the gut, including cycling and marathon running.
They found that after a ‘threshold’ of two hours the intestine gets injured and the gut becomes leaky, allowing harmful bacteria contained in the intestine to pass in the bloodstream.

They said that ‘exercise induced gastrointestinal syndrome’ may lead to acute or chronic health complications.
The authors found that running caused more gut problems than cycling in terms of numbers of incidents, severity and duration.
Between 96 per cent and 73 per cent of competitors in a 24 hour ultra-endurance marathon over 161km reported severe gastrointestinal symptoms, compared to only between 11 per cent and 7 per cent of marathon and half-marathon runners.

Negative effects of exercise kicked in at a threshold called 60 per cent of their capacity, as measured by VO2 max – which measures how much oxygen is being carried by the blood.
The review said for patients who have irritable bowel syndrome or inflammatory bowel disease, low to moderate physical activity may be beneficial, but care should be taken over taking too much exercise.
The health implications of more strenuous exercise has not been researched, but is likely to be detrimental for such patients, they said.
Dr Ricardo Costa, lead author of the research published in Alimentary Pharmacology Therapeutics review said: ‘It is recommended that a full gut assessment during exercise should be undertaken by individuals with symptoms of gut disturbances during exercise, to ascertain what is causing the issue and to develop individually tailored management strategies.’
