The study, published online in January 12, in the European Journal of heart is the first in a population important, representative and multi-ethnic to look at the links of the total amount of the meeting of time and jumps in time of indications of risk of heart diseasemetabolic diseases such as diabetes and inflammatory processes which can play a role in atherosclerosis (blockage of the arteries).
It was considered that long periods of sedentary time, even among those who also spend some time to moderate to strong exercise, have been associated with the worst indicators of cardio metabolic function and inflammation, such as the circumference of the larger sizelevels lower HDL ("good") cholesterol, high levels of c-reactive protein (an important marker of inflammation) and triglycerides (blood fats).
However, the study also revealed that, in people who have spent much time meeting, who took jumps during this period, a decrease in size and lower levels of protein c - reactive.
There was some racial and ethnic differences. The most important was that sedentary time already a negative effect marked on the circumference of the size to non-Hispanic white, but he did no difference with Mexican Americans and appears to be beneficial for non-Hispanic blacks.
Dr. Genevieve Healy, researcher at the school of population health, University of Queensland, Australia, who led the study, said: "in General, long sedentary, clinically significant findings were fat in the blood and markers of insulin resistance". The number of jumps in sedentary time, were the most significant differences of the circumference of the size. "25% Of people who took the most hopping had, on average, a circumference 4.1 cm less 25% less size.
Dr. Healy and its analyzed data from colleagues for 4,757 people 20 years and more, he took part in the study of the national review of health and nutrition between 2003 and 2006. The participants wore a small device called an accelerometer, which monitors the number and intensity of walking or running activity. It has been used in the right hip during waking hours seven days and provides information to investigators on the sedentary time and jumps in time sedentary. Measurements were taken from waist circumference, blood pressure, cholesterol levels and the concentration of protein c - reactive and also measured the levels of glucose, triglyceride and plasma insulin in a sub-sample of participants who have been fasting to attend an examination of tomorrow. Researchers have statistically represented socio-economic-demographic differences among participants in the study, their medical history and lifestyle (smoking, alcohol consumption, diet).
The less sedentary time was 1.8 hours per day, the majority 21.2 hours per day. the number least of jumps in seven full days was 99, and the majority was 1,258.
Dr. Healy, said: "are also accepted for scientifically the benefits of regular participation in the exercise of moderate to high intensity and by the general public." However, the potential adverse effects of prolonged sitting (which is something we do on average more than half of our days), as soon as it is done. Our research highlights the importance of sedentary time extended for health risk behaviour to ensure notice explicit on the future directions of public health. In particular, the results may have implications for the configuration where the prolonged meeting is widespread, as in the offices.
"Our research has shown that even small changes, which could also be that the defence of a minute, could help reduce this risk to health." It is likely that regular breaks extended during meeting time could be easily incorporated into the work without negative effect on productivity environment, but it must always be determined by further research. It could be used as a motto for this message. "
He said that existing health and safety guidelines recommend regular changes in posture and a variety of tasks and that they would contribute to incorporate breaks most of the session of the working hours and could lead to less sedentary overall time. Practical advice that might help to do so in a book based on the included office space:
Quality to receive telephone calls.
Walk to a friend over the phone or electronic mail;
permanent meetings or encouraging regular breaks, meetings of people to walk or go to a bathroom at a different level;
Centralize things like printers and garbage cans so that you have to walk to them;
Take the stairs instead of the elevator as soon as possible.
Dr. Healy said that the size of the differences in metabolic and inflammatory of the cardio biomarkers risk of various between 25% upper and lower of the people of his sedentary time is large enough to suggest "in theory, reductions in the overall population in sedentary time of one to two hours per day.", could have" "a substantial impact on the prevention of cardiovascular disease."
He concludes: "prolonged sedentary time is likely to increase with future technological and social innovations, and it is important to avoid long periods of sitting and to move more throughout the day." An important message of Deputy of health, with the recommendation for regular participation in exercise can reduce and regularly breaking sedentary time. While most of the evidence of causal nature is required, less time meeting would be unlikely to harm. "At least it would contribute to the overall increase in daily energy costs and could help prevent the dollar rising".
