Dyslipidemia is a problem with the metabolism of fats. Patients with hyperlipidemia, hyperlipidemia, excess cholesterol, excess triglycerides and low levels of HDL (good cholesterol). Physical activity balances the level of fats in the blood in patients with lipids in the blood, but the improvement is related to the amount of physical activity more than to the degree of exercise that is performed. This is revealed by new research published in the latest issue of the New England Journal of Medicine.
A total of 111 overweight men and women with mild to moderate blood lipids were involved in the research. The participants were divided into a control group without physical activity (6 months), and into three training groups (8 months): high and high physical activity, low and high physical activity, and low and high physical activity Medium. All participants were asked to try to maintain their starting body weight.
It was found that in 84 of the participants who completed the fixed program, the effect of physical activity was the best for most of the variables determining the level of lipids, except for the level of general cholesterol, and the level of LDL cholesterol. The results were more prominent among the participants in the group that did physical activity in a large amount and at a high degree.
Participants in the large amount training group showed significant improvement in 10 of the 11 variables that determine the level of lipoproteins, compared to participants in the small amount and high level training group. Similarly, participants in the small to large degree training group showed significant improvement in 11 of the 11 lipoprotein level-determining variables, versus the control group.
On the contrary, when they compared the improvement in the level of lipoproteins in participants in the training group with a small amount and a high degree, versus the levels of lipoproteins in participants in the training group with a small amount and a medium degree, there was no preference for either group over the other. In addition, with the exception of the control group, participants in both training groups showed significant improvement in all 11 lipoprotein level-determining variables.
The researchers summarized these results by saying that the amount of physical activity had a greater effect on the level of lipoproteins than the degree of activity. These data refute the conclusion reached by previous research that relied on physical activity in a small amount, because physical activity has a limited impact on the level of lipids.
