Too many bad Sitting With Little Sport

Sitting all day may greatly increase the risk of diseases related to lifestyle, even if someone adds dose for moderate or vigorous exercise routine, said several scientists.

Health benefits of physical activity that accelerates the heart rate no longer debated; that, among other things, help prevent heart disease and blood vessels, diabetes, and obesity.

But scientific findings recently also showed that the condition of prolonged motionless while people sit may be independently associated with such conditions.

"When sitting should be defined as muscle activity and not a lack of exercise," concluded a team of Swedish researchers.

"We need to consider that we are dealing with two different behaviors and its impact," they report in the Journal of Sports Medicine, UK.

Led by Elin Ekblom-Bak of the Karolinska Institute in Stockholm, the scientists proposed "new paradigm of psychology did not move", and urged other researchers to rethink the definition of lifestyle sit constantly.

They pointed to a study recently of Australian adults who showed that every day an hour increase in the sitting while watching television increases metabolic syndrome rates among women by 26 percent - no matter the amount of moderate exercise diligently-until-done.

Daily physical exercise for 30 minutes reduce the risk of the same percentage, thus showing that a person who had spent most of her spare time sitting or lying on the couch, for example, can eliminate the benefits of using "treadmill" or cycling.

Metabolic syndrome is defined as the presence of three, or more, factors including high blood pressure, abdominal obesity, high cholesterol or insulin resistant conditions.

New research is needed to see if there is a causal relationship between the immobile and this condition and, if so, how do they work, the researchers said.

One candidate is "lipoprotein lipase" - an enzyme produced in fat cells (adipocytes) and tied at the capillary walls - or LPL.

This enzyme plays an important role in the break down of fat in the body into a useful form.

A recent study shows that LPL activity, in mice, in striking down through stretching activities - as low a level that enables one-tenth of a rat running.

LPL levels for such activities "not too different from the rats exposed at levels higher motion", the scientists said.

"This emphasizes the importance of local muscle contractions, and not a strong stretch," said the researchers reported the French news agency, AFP.

All studies showed that people not only need frequent exercise, but also to avoid sitting in one place for too long, they said.

Walk up the stairs and not use the elevator, rest for five minutes from the desk, and walk when possible to deliver a messenger and not a car is strongly recommended. (AntaraNews)
