California, Walking and running are the most popular
physical exercise. Various studies conducted to discover which is better
effects on the body. Are the conclusions the researchers?
According to the researchers, large or small effect
of this practice depends both on purpose to do it. If for example you want to
control your weight, then you should run, as quoted by the NY Times.
In a study published in Medicine & Science in
Sports & Exercise, researchers examined survey data from 15 237 32 215
runners and walkers registered in The National Runners and Walkers' Health
Study, a large survey conducted at the Lawrence Berkeley National Laboratory,
California.
Participants asked for information about weight,
waist circumference, diet, and weekly mileage walking or running when they join
in this survey. This data was then asked again 6 years later.
As a result, people who exercise almost run leaner
compared to those on foot. Over the years, people who ran maintaining body mass
and waist circumference they are much better than walking.
Reason ran better in the regulation of body weight
than is unclear. However, experts say that running burns more calories per hour
than walking.
Another reason is the effect of running on appetite.
In a study published in the Journal of Obesity, revealed that pedestrians take
about 50 more calories than they burn during a 1 hour walk. While running to consume
200 fewer calories than they burn calories after running for 1 hour.
After each run and walk, runners proved to have
increased levels of the hormone peptide YY. This hormone is proven to work to
suppress appetite. While the people who walk not have elevated levels of
peptide YY, appetite so they stay warm.
However, studies also show that walking can be just
as beneficial as running.
"If you plan to walk, but want the same number
of calories burned as running, then you have to walk about 1.5 times as much
and takes about 2 times longer," said Paul T. Williams, a scientist
Lawrence Berkeley National Laboratories.
