Physical activity reduces the risk of the metabolic syndrome this much

News: Dec 22, 2015

Only a minute’s worth of training per day is actually enough to reduce the risk of cardiovascular disease. A study by researchers at Sahlgrenska Academy and GIH, has studied how risk decreases when inactivity is exchanged with physical activity, depending on the intensity level.

A sedentary lifestyle increases the risk of the so-called the metabolic syndrome (MetS), a constellation of factors that increase the risk of cardiovascular disease. The factors increase the risk individually, but combined they increase the total risk.

In short, it is about the metabolic syndrome of abdominal obesity in combination with risk factors such as blood lipids, cholesterol, high blood pressure and reduced glucose tolerance or diabetes type 2.

Exchanged inactivity

Researchers at Sahlgrenska Academy, the University of Gothenburg have together with GIH (Swedish School of Sport and Health Sciences) studied how the risk of the metabolic syndrome is affected when inactivity is exchanged with three different intensity levels of physical activity.

“The results show that it is sufficient if inactivity is exchanged with ten minutes of low intensity physical activity, which generally corresponds to a walk, per day in order to significantly reduce the risk of the metabolic syndrome. If this physical activity is done at medium or high intensity level, as with exercise/training, the risk is further reduced,” says Mats Börjesson, Professor at Sahlgrenska Academy.

836 participated

In the study that was published in the European Journal of Preventive Cardiology, 836 men and women between the ages of 50 and 64 participated in the study, which is part of a larger and ongoing SCAPIS study financed by the Swedish Heart-Lung Foundation.

The participants underwent a large number of tests and their physical activity was measured with an accelerometer more than 14 hours per day. On average, they were entirely inactive nearly 8 hours per day.

10 minutes per day

The study examined how the risk of the metabolic syndrome is reduced with low, medium or high levels of physical activity when inactivity is exchanged with one minute to 120 minutes of motion per day.

The curve representing results with high intensity physical activity, showed the most dramatic drop. With 10 minutes of high intensity training per day, the risk is halved and is completely eliminated with one hour of training per day.

“This means that people who are very active no longer bear the risk factors that are involved in the metabolic syndrome,” says Göran Bergström, Professor at Sahlgrenska Academy and Chair of the entire SCAPIS study.

The table that shows how much physical activity/motion along with the level required to reduce the risk of cardiovascular disease may be of great use to doctors to explain the importance of physical activity to patients in a simple way.

FACTS
SCAPIS stands for Swedish CArdioPulmonary bioImage Study and is a globally unique research project within heart, blood vessels and lungs. The study is led by a national research group, conducted by six different university hospitals in Sweden and coordinated by Sahlgrenska University Hospital and the University of Gothenburg. The project’s main financier is the Swedish Heart - Lung Foundation but it also receives significant contributions from the Knut and Alice Wallenberg Foundation, Vinnova, the Swedish Research Council and the University Hospital itself.
Within the framework of the SCAPIS study, comprehensive studies on the heart and lung status is being done on 30,000 Swedes in the 50-64 year age group.

In 2012, a pilot study was conducted in Gothenburg where over 1,100 persons were examined and now a further 5,000 men and women have been randomly selected to participate. The research that is the basis of this published study has been done within the framework of the pilot study in Gothenburg.

The article, Isotemporal substitution of sedentary time by physical activity of different intensities and bout lengths, and its associations with metabolic risk, was published in the European Journal of Preventive Cardiology, online in December.
