Due to working during most of the limited daylight hours, I have been using the dreadmill lately. The minimum % incline on my dreadmill is 1.5% (can’t get to zero).
Do any of you have any ideas about equivalent times would compared to 0% incline? I have been doing both hard and somewhat-less-than-hard intervals, between 6:00 and 10:00 minute mile pace. The dreadmill speed limit is 6:00 min miles.
What, for example, would a 8:00 minute mile at 1.5% incline be equivalent to? Maybe 7:45 minute miles?
By my calculation, a 1.5% incline is 1.5 feet in 100 feet, which is 0.859 degrees. Doesn’t sound like much, but I can feel it.
I supposed the heavier one is, the more effect an incline would have. I am about 150 pounds max in the off-season.
Since a treadmill doesn’t require you to use energy to accelerate your body forward or through the air
it might actually be near the same as running on flat ground.

I think runners magazine said something like 1% is equivelant to running outside ±.5% so you are probably closer to what it is like running outside than 0%
.

I think you should be more concerned with how far off the treadmill speed is to outside then the treadmill incline.
However 1 percent is normally the accepted incline for it to be similar to outside.
Not quite correct. You do still have to accelerate your body forward, otherwise you’d fly back with the belt. But you’re correct that you don’t have to fight air resistance, though you also don’t get the cooling effect of running through air. Another reason you need to set the incline to above 0 on treadmills is to compensate for the fact that most compress as you land toward the front and thus would be like running down a very slight decline rather than running flat.
i think the apparent speed difference is due to misleading sensory information (running without moving through space). In our lab we’ve tested many runners who said they thought the belt was faster than advertised (we check with a tachometer to verify).
as for the grade, i think the 1.5% would be pretty close to running outside (i would advise running a fan though, for cooling). I believe studies have equated 1% on the treadmill to 0% outdoors, but we have also found that there is exceedingly little difference between 0% and 2% on the treadmill (as such, for max tests we go from 0% right up to 4%, then +2% after that).
I’m going with Grant on this one. My treadmill speed seems to be way off from what I do outside.
I used to run with my garmin on it with footpod. all the treadmills that i have been on at teh gym have been reading between 1mph to 2mph slower then what they were actually going. normally the faster you actually went the more the treadmill would be off. It actually gets pretty rediculous when they are all that far off.

I have to disagree, as said in my post before this. There is no way i am only running 6.0-6.5 on the treadmill, yet i can magically run outside at 7.5 without any problems, with wind and hills. Yet if i set it at 7.5 i feel like i am doing a tempo run instead of a easy/moderate run.
well, i have not used your treadmill, i was simply pointing out that very experienced runners (olympic trials qualifiers running 100mi/wk) on a treadmill at a verified speed thought it felt faster than it was.
your treadmill may also be off, but i do believe that our motor/sensory integration is off due to running in place.

but how expensive is this treadmill that they are running on. Im sure there are treadmills that are set right but i would say the majority at a gym are probably going to be off.
the treadmill i test on is an expensive setup, but the verification is simple, and can be done with a tape measure and a tachometer - just measure the belt length and rpm (put a piece of reflective tape on the belt to reflect the ‘laser’ from the tach). if you have a friend there, have them measure the rpm once you get going (as your weight on the belt will slow it down somewhat).
Grant - Do you set the treadmill at 0% or 1% or ?% grade??? I’m just curious since you seem to be saying that you run slower on the TM than outside whereas I have had the opposite experience, even using 1% grade and especially if I put it on 0%. Due to this, I have given up on running on them unless it is absolutely pouring outside or icy. I’d rather run on an accurately measured track so that I know for sure that I’m going the pace my watch says I’m going…
You understand that what caused the plane to move forward in that is that the thrust far outweighed the rolling resistance right? That doesn’t show that you don’t have to accelerate in order to stay in the same place on a treadmill (which you do and so did the plane).
If you want proof that you have to accelerate your body to stay in the same place on a treadmill it’s very easy to prove to yourself. Get a treadmill going at 2 mph then stand on it but don’t put any energy into moving your body at all and tell me if you stay in the same place or get dumped on your bottom at the back of the treadmill. If you want to stay in the same place, you have to accelerate your body forward at an equivalent rate to the treadmill belt accelerating backwards (relative to you). So my point still stands.
If in all of this rambling I totally missed what you were trying to point out with the Mythbusters reference, I apologize ahead of time.
You are right that the mythbusters episode is a different scenario and proves nothing about accelerating your body through space on the treadmill.
Its just the general failure to grasp physics that is the same.
On a treadmill, you accelerate only your legs
Outside, you move your body through space
You aren’t accelerating your body, just turning over your legs. This mostly only applies as the pace changes but since speed will drop between each stride a little it applies at a constant pace too.

…but I should note the chart isn’t accurate for me, at least if I’m using my heart rate as a gauge of effort. In my case, the cooling effect of having a breeze more than compensates for increases wind resistence. My HR tends to be rather high on treadmills, as I’m a hot/sweaty mess after the first 10 minutes.
