Difference in swimming in different depths

Shallow depth will cause more bounce back if a pack or loaded swim practice is causing lots of waves. Lighting seems to be more of a concern for me. Dark pools & turns make sighting turns more difficult for me.

All things being equal a deeper pool will be faster(to about 7 1/2 ft as I remember,depth past that doesn't matter.Before they built the Indy pool they did tests to see how far the turbulence from a swimmmer extended.)It really doesn't matter for workout as long as it is deep enough for your turns

I have some experience with swimmimg and when I have try a shorter depth I felt like the swimmimg was a bit more easy I've noticed the same thing. I think it's an illusion - optical or otherwise. In a shallow pool, when your eyes are closer to the bottom of the pool, you can see the bottom more clearly and the amount of the pool bottom that's in your field of vision is smaller and thus appears to be moving at a faster rate. When Long Beach's Belmont Plaza pool is set up for the annual and very well-run master's short-course-meters meet, the starting blocks are in the deep end, with the diving boards, and the turn is in relatively shallow 6 feet of water or so. The deep end is dark, thanks to the early 1960s design, while the turn has pretty good lighting. I've always felt the swim into the shallow turn was faster than the swim into the deep end. The first time I swam an IM in that pool, for example, as I killed myself trying to get to the finish in the deep end, I felt that I was just floating and the bottom was hardly moving.

Deeper pools are supposed to be faster. In a deeper pool when you turn you can get under your wake. Also a shallow pool apparently can reflect the turbulence back at you. What matters more though I think are the lane ropes and the walls. Good lane ropes can keep your lane calm. For the purpose of training I don't think the depth matters much.

The reason is they want the pool deep to prevent turbulence. As stated before if the pool is shallow this turbulence can bounce off the bottom. The deeper the pool the less this will be a problem. The turbulence has much more space to diffuse in a deeper pool. FINA facility standards specify a minimum depth of 2 meters for Olympics and World Champs with 3 meters recommended.

Well, I meant 71/2 the official for olympic pools, whats the reason for this mark versus a shallow pool in where you can stand

In deep pools I also feel my muscles are exercising more, do you think this could be true?

Your muscles do not know -- it's your brain that is the difference.Having been in very shallow pools in H S the deeper pools of now are much nicer to swim in .

What´s the reason for the 7ft mark in olympics pools then? In deep pools I also feel my muscles are exercising more, do you think this could be true? Maybe they have new data.It is certainly cheaper to make a 7'pool vs 71/2.
