Office workers can stave off health problems associated with sitting down all day by regularly exercising, a new study has found.

Being physically active may offset some of the deleterious consequences of spending large amounts of time not being active, the paper published in BMC Public Health has revealed.

The study further emphasises the importance of physical activity in the promotion and maintenance of health.

In contrast, people described as 'couch potatoes' are putting their health at risk by spending too much time sat down and not exercising, the paper said. Low sedentary (sitting) time in the absence of physical activity is associated with higher HDL (good) cholesterol levels.

Sedentary behaviour is defined as habitual sitting time. Higher levels of sedentary behaviour are associated with worse health, whereas higher levels of physical activity are associated with better health. However, the extent to which the combination of these behaviours influence health is less well-known.

They grouped people into the following categories, including the physically active (those meeting the recommended guidelines for physical activity) and low sedentary 'busy bees', the physically active and high sedentary 'sedentary exercisers', the physically inactive (those not meeting the recommended guidelines for physical activity) and low sedentary 'light movers' and physically inactive and high sedentary 'couch potatoes'.

Lead researcher Dr Thomas Yates, from the Leicester Diabetes Centre and the University of Leicester, concluded: "We demonstrate that in comparison to adults who are physically inactive with high sedentary time, those who are physically active have a more desirable health profile across multiple cardiometabolic markers even when combined with high sedentary time. In contrast, low sedentary time in the absence of physical activity is associated with higher HDL-cholesterol levels.
