YOUR VIEWS:Running V walking

from a professor of medicine :
"All things being equal, you will burn more calories by running an
hour than walking an hour. It is true that walking a mile will burn
more calories than running a mile -- although it takes longer to do
so. When you run a mile, you're burning mostly sugar, or
carbohydrates, which is how your body gives you fast energy in bursts.
When you walk a mile, it gives your metabolism time to switch from
burning carbohydrates to burning fat."

agree or disagree? own views?

I don't really understand the metabolism "switch" he's talking about.  If he's saying your body burns carbs through running and fat through walking, why would your metabolism need time to switch over if you were never running in the first place?

I'd just rather run twice as far and burn more calories rather than overthinking it.  But I love to run.

That person is just saying that your workout time is significant. Walking 30 minutes might be equal to running 15 minutes, for example - but obviously, that means running 30 minutes is even better.

The 'switch' means that your body burns off sugar for a certain amount of time, but when you keep exercising after that time, you'll begin burning fat. Whether or not you're walking or running or any other cardio, this is the same - it just means that shorter-but-more-intense exercise isn't necessarily better.

the mad professor.  what i mean is, what's this guy trying to say, and why doesn't he just say it?  whatever, i think i get his message.

but in our world, we exercise for time.  we have 30 minutes to get in a workout, or we have all day to get in three 20-minutes sessions.  whatever the situation, very few people say, "i have to traverse 10 miles today.  how should i do it?  bike? walk? run?" 

if you're going to do something for an hour, run.  if you can't or won't, then walk.

i dont even understand what this is trying to say?

both are good exercise...but i feel like running is a better conditioning tool.  anyone can walk, but not everyone can run [well, do it and enjoy it].  running also batters your body, while walking is gentle.  

walking to burn calories...kinda time inefficient.  walking to get in some exercise, A+.  running to burn fat..probably not gonna happen unless you can sustain it for more than 20-30 min.  running for heart health and body conditioning, A+.

was the professor trying to argue something?  that one is better than the other?  one will always be better than the other...it all depends on the circumstances..
