I mean, since all you are doing is pushing the belt back, your weight shouldn’t matter as much; only your fitness should matter.
In actual running, you push your mass forwards, so your weight matters much more.
Agree or disagree?

Wind resistance would play the biggest factor, no?
another treadmill physics thread...
the only things different about a treadmill than normal running are:
1) no wind resistance
2) resistance between the belt and the plastic plate beneath it can slow the motor down if it's not strong enough
at a constant speed, on an ideal treadmill, the physics are exactly the same as outside

Nah, it pulls your foot back. All you have to do is jump higher to make treadmill running easier.

Good troll post, Jeff, although it's been done.
Ignoring other factors (wind resistance being the big one), the amount of work it takes to remain stationary on a belt moving 10 mph is identical to the amount of work required to move 10 mph on a stationary surface.
If you make the treadmill bigger and bigger in your mind, you will start to see the fallacy of the "belt helping you" argument. If you were on a train that had one long car, and you ran down the aisle as it went 10 mph, you would certainly not feel as if there was a belt pulling your feet back as you ran 10 mph to remain in the same place relative to outside the train. However, it would be the same thing.
Only on an antigravity treadmill
It is a softer surface than concrete.
You push your mass forward relative to your foot on the ground in either case. It's not moving at all relative to the ground or the treadmill, so for your center of mass to be moving at a certain speed relative to the treadmill or ground, part of you must be moving even faster. Since that part alternates between right and left, each has to be accelerated in turn, and this requires the same amount of force in either frame of reference.
This is the basic principle of my recently-invented Wheel Method of running. Just like a wheel, everything is moving forward except the point of contact with the ground. Like a wheel, your best means of going fast for a long time is minimizing braking forces and inefficient movements. Just roll.
If de plane is too heavy, it won't be able to take off.

3) no cooling effect from cutting through the air. It's easier to get overheated on a treadmill when the air temperature and humidity is lower outside

This has been done to death 1000 times.
You're wrong - retake physics 101, or just google it. The only advantage against running on the flat outside in still air is that there's no air resistance.
(Also treadmills are often poorly calibrated - so you're not actually doing the pace it says you're doing - but that's a separate issue.)

To add to what mebert said, the advantage of having no air resistance is cancelled out by the lack of the cooling effect of air resistance. Your heart rate increases at any given pace as your body attempts to dissipate the heat.

Incorrect. The arms and legs are in motion relative to the air, and the trailing leg and arm are in faster motion indoors than in still outdoor air, where the trailing foot is stationary instead of moving backwards. There may be less cooling effect, but there is one.
It's easier to get overheated on a treadmill when the air temperature and humidity is lower outside
If indoor temperature is higher than outdoor, then it is not likely that relative humidity will be higher too.

Sounds like pop-physiology.
What’s the use for these troll posts?

I've got to be careful on a treadmill with my chronic gas problem. It's one thing when I'm outdoors on the trails or track and there's a breeze or wind. But man...in these closed environments of some gyms where they cram all the treadmills in one area, having a gas problem is bad news! ?
