Are You a Cardiac Patient? Leave Your Chairs and Be On the Move to Stay Healthy

Sitting too much for a long time will worsen the health of people suffering from cardiac ailments, revealed a new study.

"Limiting the amount of time we spend sitting may be as important as the amount we exercise," said study lead author Stephanie Prince from University of Ottawa in Canada.

Sitting Down At Work Is No Worse for Health Than Standing Up: UK Study
Any stationary posture where energy expenditure is low may be detrimental to health, be it sitting or standing, which raises doubt on the benefits of sit-stand work stations.

‘Heart patients must avoid sitting for longer periods even though they exercise regularly, as it worsens their overall health.’

Previous research has shown that being sedentary increases the risk of cardiovascular disease but until now its effect on patients with established heart disease was unknown.

"Sitting, watching TV, working at a computer and driving in a car are all sedentary behaviors and we need to take breaks from them," Prince explained.

The current study investigated levels of sedentary behavior and the effect on health in 278 patients with coronary artery disease. The patients had been through a cardiac rehabilitation program which taught them how to improve their levels of exercise in the long term.

Walk for Just 10 Minutes After Sitting for an Extended Time
University of Missouri research found that blood flow in the popliteal - an artery in the lower leg - was greatly reduced after sitting at a desk for six hours.

Patients wore an activity monitor during their waking hours for nine days. The monitors allowed the researchers to measure how long patients spent being sedentary, or doing light, moderate or vigorous levels of physical activity.

The researchers also assessed various markers of health including body mass index (BMI) and cardio-respiratory fitness. Next they looked at whether the amount of time a person spent being sedentary (which was mainly sitting) was related to these markers of health.

Frequent Breaks Best to Cut Long Sitting Hours At Workplace or Home
King's College London research have shown that increasing the levels of physical activity is likely to be much less effective at reducing prolonged sitting.

The results showed that patients who sat more had a higher BMI. They also had lower cardio-respiratory fitness. The study was published in the European Journal of Cardiovascular Prevention.
