Mortality of sedentary is up to 70% higher than the trained.
The ideal is to have more intense physical activity, and not merely walk.
Individuals with low aerobic capacity have a risk of mortality 70% higher than the trained. If we think only in cardiovascular disease, increased risk is about 60%, again compared with individuals with good aerobic capacity.
More Health Focus
In reaching this conclusion, Japanese researchers conducted a comprehensive review of studies published on this topic. We identified more than 30 scientific papers, involving more than 100 thousand people. Participants were aged between 37 and 57, and monitoring the polls reached 26 years of duration.
Scale
Aerobic capacity is assessed through stress tests which can determine its maximum and can be measured in a unit called MET. Check out the range of call activity index Duke below:
1 to 4 metabolic equivalent
Activities homemade daily.
Walking around the house.
Walking with 1-2 obstacles in the plane to 3-5 km / h.
5 to 9 Metabolic equivalent
Climbing stairs, walking on the hill.
Walking in the plane> 6 km / h.
Running short distances.
Moderate activities (golf, dancing, walking in the mountains).
10 Metabolic equivalent
Extreme sports (swimming, tennis, cycling).
Toil.
Using this standardization the researchers were able to define 3 tracks of conditioning and its impact on the risk of dying. Below 7.0 MET was low aerobic capacity, from 8.0 to 10 MET was mid-range and above 10.9 MET were the most conditioned.
Healthy but sedentary
Healthy but with low aerobic capacity has a 40% greater risk of dying from any cause than those with intermediate ability. The risk of death from cardiovascular disease is 47% higher for sedentary than those with intermediate ability.
An important finding of this review was to quantify the improvement in aerobic capacity on the health of individuals. For each increase of 1 MET in the maximum abdominal circumference of individuals decreases 7 cm, systolic blood pressure fell by 5 mmHg. Triglycerides fall, as well as fasting glucose, and there is an increase in HDL cholesterol, the good cholesterol.
As aerobic capacity can be determined by a cardiac stress test, this might be a good tool for doctors monitor their patients, demonstrating the benefits to motivate them.
