" Diet and exercise, "goes the old mantra- It's hard to better give a short cut to the basics of Of course, the picture may be more complicated, but a new study recalls the importance of both elements, stating that otherwise healthy, smart-eating people who have not exercised are still high In fact, they had the same risk as people who were overweight
The study used data from the National Health and Nutrition Examination Survey and focused on people between the ages of 4o and 79 years. The researchers divided the data into two categories, comparing individuals with a healthy body mass index (BMI) to those with an overweight BMI, and then rated the two groups to Her z-vascular risks. Specifically, they focused on people who had a healthy BMI but had properties that could increase cardiovascular risk: an unhealthy sagittal abdominal diameter (a fancy way to say "a gut"), shortness of breath after exertion, and less than recommended training levels. They were also adapted for other factors, age, race and gender.
Having cracked the numbers, they found that even those with a healthy BMI who had a sedentary lifestyle had approximately the same risk of cardiovascular disease as people with overweight BMI. In an interesting pleat, they also found that people who sit for long periods of time – which has recently been linked to unhealthy outcomes – have reduced cardiovascular risk, even though they were physically active.
In other words, exercise correlated with a lower risk of cardiovascular disease, even in people who otherwise sat much. And, as a rule, lack of exercise is associated with an increased risk of cardiovascular disease, even in otherwise healthy people.
There are some reservations, according to the authors. There is some discussion as to whether the standard method of calculating the risk of cardiovascular disease actually overestimates the threat in some populations. Some of the physical fitness data has been self-reported meaning that it is not an accurate measurement. Overall, however, these data should be generalizable to most adults in the US.
The findings, the authors suggest, suggest that focusing on BMI as a healthy goal is not enough. Those affected may reach the appropriate weight for their size. However, if they do not exercise, the study has shown that they have the same risk of cardiovascular disease as overweight people. The lesson? When it comes to your heart health, exercise is important.
