Playing a vertical game of football underwater would be very difficult, and likely hazardous.
1. As anyone who's gone diving will attest, you physically can't dive very quickly. You have to constantly equalize your ears as you descend to avoid pain. This would limit how fast you can go down. (Especially at shallower depths, where the effect is more pronounced.)
2. At deeper depths, you'll quickly hit your no-decompression time limits. At 40 meters depth, you only have 8 minutes of no-decompression time. And that's if you don't run out of air first.
3. Recreational diving is usually limited to 130 feet / 40 meters - and that's with extra training. At deeper depths not only does nitrogen have a narcotic effect, but oxygen quickly becomes toxic. A 100 meter dive is well within the realm of technical (not recreational) diving and would require special breathing gas and careful planning.
4. Rapidly going up and down, like you'd need to play a game of football, is recipe for giving yourself the bends. You need to ascend slowly. (And again, that's assuming you haven't exceeded your no-decompression time.)
On the other hand, you could play a horizontal game just fine. You're practically weightless underwater (at neutral buoyancy), so the game would be the same the same either way. (For Ender's Game fans: "The enemy's gate is down.")
- dragonsky67 8y agoHow about playing football whilst free diving and so avoid the joys of gas bubbles forming. The current free dive depth record is something around 250 meters and people who do free diving spear fishing frequently dive down to 20 - 30 meters. It would change the game somewhat but I could imagine having a ball that was buoyant at about 10 meters would force the play underwater. Having the goals on the bottom either side of a submerged wall would force vertical movement. You would have a challenge with viewing the action, but there are some pretty amazing underwater drones around so I think you could really get with the action.

When reaching the surface, athletes are required to say "I'm Ok" and do a sign with their hands. Some times they can't do that because they're in a hypoxia state and very close to pass out. it's not a situation you want in a contact sport.
