Experts discovered that as little as 14 days spent sitting around reduces our muscle mass, increases body fat and raises the potential for high cholesterol. And they warned that taking at least 10,000 steps a day – widely regarded as a target for maintaining good health – should be something people strive for to avoid the risk of disease.
Dr Dan Cuthbertson, who led the new study and is presenting his findings at the European Congress on Obesity in Porto, Portugal, said any physical activity – even walking – is better than being sedentary.
He said: “This doesn’t need to be structured exercise – it could be things like getting off the bus a stop earlier or walking to the shops instead of driving. If you think of a typical mum at home who is always busy and on the go but doesn’t go the gym regularly, there are still significant health benefits in what she’s doing.”
Dr Cuthbertson’s team, from the University of Liverpool, followed a group of 28 healthy people of a normal weight with an average age of 25. Participants usually took 10,000 steps per day or more but did not have more than two hours of structured exercise – such as going to the gym or playing sport – per week
The results showed significant changes to the body, including loss of muscle mass (average loss 0.36kg) and increases in total body fat, with central body fat going up by around 1per cent. There was also an increase in liver fat and an increase in bad cholesterol markers. Overall, cardio-respiratory fitness levels also declined.
“The take-home message is two-fold,” he said. “If you do formal exercise, it may not be enough and keeping active as part of your daily life is important. And for those who don’t exercise, avoiding prolonged sitting and increasing your daily step counts has clear health benefits.”
He added: “It does appear that there is something in this idea of 10,000 steps a day being good for you. People have become obsessed with 10,000 steps a day and this research shows it’s a good thing.”
“If you take obese people, older people or those at risk of diabetes, all the risks of a sedentary lifestyle may be even greater,” he added. “Our day-to-day physical activity is key to abstaining from disease and health complications. People must avoid sitting for long periods of time.”
So once again, the virtues of using a standing desk everyday has significant health and wellbeing benefits. Why wait until it’s too late?
