Would a giant human run fast or would they run slow like in movies/shows?

1. If they’re anything like humans who actually grow really tall because of certain diseases or else just happen to be naturally tall they’d be super slow.Most of the time in sports, after a certain height people just get slower and slower.

   If a man with gigantism who is 7,9 is barely mobile then you’d have to think one who was like 14 foot probably couldn’t do anything more than a zombie shuffle

2. Depends if their body can handle that size. If there is no structural weakness and can exert the same force as a normal size person, they would run pretty fast.

3. They would collapse under their own weight

4. How giant? Like 10’ or like 30’?

5. Square cubed law needs to be considered. Aka, as you increase size squared you increase weight cubed.

   Assuming a 1:1 increase in humans a human will move slower as it gets bigger.

6. The movement itself would look and feel slow, but the distance traveled would be greatly increased.

7. Big things don’t move slow, they look slow because their movement is “smaller” compared to their size.

   Trains are a real life example. Drivers see a train slowly approaching the crossing, they think they can pass and bam! they are ran over by a not slow train.

   Do you know how fucking fast is the Moon?

8. Giant human?

   You mean just a tall person?

   Odd way to ask a question.

9. Real fast lol , just like elephants we think they are slow big fucks , just google an elephant speed when charging at something, it’s more than a small 🏍️ lol

10. Depends how big. Do you mean 12 feet tall or 120 feet tall?

    The only advantage to being bigger is longer stride length. Everything else gets worse. Your muscle and bone strength increase to the square of length (e.g. 4 times the height, 16 times the strength) while your mass increases to the cube of length (e.g. 4 times the height, 64 times the mass) and the rotational inertia of your limbs increases to the cube (e.g. 4 times height, 1024 times the rotational inertia).

    If you’re walking on level ground, your average vertical foot forces must be equal to your body weight. Standing still, each foot is 1/2 BW. Walking, when each foot is on the ground ~50% of time, it’s 1 BW. Running, where there’s an airborne phase, it can be 3 times body weight. Now consider that your weight increases faster than bone or muscle strength.

    If the person is simply big but within the normal scope of human variation, they’re likely faster, but as you get to increasingly outlandish sizes, these nonlinear effects predominate, and the giant person get relatively slower and eventually absolutely slower. Beyond some point, their legs snap just from standing up.
