Moderate Exercise Might Be Healthier Than Intense Workouts

Just a 30-minute daily walk can help stave off diabetes, heart trouble,

study finds

 

(HealthDay News) -- Moderate exercise, such as walking 30 minutes a day,

may offer better protection against diabetes and heart disease than a

more rigorous workout regimen, concludes a U.S. study that included 240

middle-age, sedentary people.

 

" On the surface, it seems to make sense that the harder we exercise, the

better off we'll be, and by some measures that's true, " lead author and

exercise physiologist Cris Slentz, of Duke University Medical Center,

said in a prepared statement. " But our studies show 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. More intense exercise doesn't seem to do that. "

 

Perhaps even more surprising is that some of the benefits achieved

through moderate exercise seem to last much longer than the benefits

gained through more intense training, Slentz said.

 

The study was published in the August issue of the Journal of Applied

Physiology.

 

The participants in the study were divided into four exercise groups:

high amount/high intensity; low amount/high intensity; low

amount/moderate intensity; and a control group that did no exercise. The

volunteers started with a two- to three-month " ramp-up " period and then

continued their exercise programs for six months.

 

The Duke team found that no amount of exercise significantly changed

levels of low- density lipoprotein (LDL -- " bad " cholesterol). However,

length and intensity of exercise did improve levels of high-density

lipoprotein (HDL -- " good " cholesterol), and that benefit was sustained

over time.

 

The study also found that low amount/moderate intensity exercise

significantly lowered levels of triglycerides, which are particles that

carry fat around the body and are also a good indicator of insulin

resistance, a marker for diabetes. Reducing triglyceride levels lowers a

person's risk of diabetes and heart disease.

 

" A proper exercise program appears to be able to lower a person's

insulin resistance in just a matter of days. We were also amazed to see

that the lower triglyceride levels stayed low even two weeks after the

workouts ended, " senior author and cardiologist Dr. William Kraus said

in a prepared statement.

Nice conclusions.

Maybe Yoga and others holistic practices of low amout, provides what the

research say.

 

Thanks
