Health benefits of moderate exercise

A new study finds that moderate exercise may be able to provide better protection against diabetes and heart disease than a more intense workout regimen. Researchers from the Duke University Medical Center report that “a modest amount of moderately intense exercise is the best way to significantly lower the level of a key blood marker linked to higher risk of heart disease and diabetes. Some of the benefits achieved through moderate exercise seem to last much longer than the benefits gained through more intense training”

Exercise did not significantly changed the levels of low-density lipoprotein (LDL cholesterol). Duration and intensity of exercise did improve levels of high-density lipoprotein. Low amount/moderate intensity exercise significantly lowered levels of triglycerides, which is correlated to a person’s risk for diabetes and heart disease.

I think that “intense” exercise (e.g., interval training) has its role in a well-balanced fitness program. It increases a person’s anaerobic energy system, and creates a margin of safety from a functional standpoint. IMHO, one is better able to handle the occasional physical stresses in daily life much more effectively. Strength training would also be a necessary component in creating an optimal exercise routine.
