Please dear god cite the study that proves that lung capacity gives you better aim. The last time the shooting was mixed at the olympics, it was won by a cis woman!
Pretty sure you're getting the archery mixed up with skeet shooting, performed with a gun. I have checked the Olympics records since 1900, and can find no mention of a mixed event.
No-one needs to do a "study". You realise that when you breathe, your chest moves, yes? That means it knocks the bow and your aim aside, too. One technique to deal with this is holding your breath entirely while you take the shot. The greater your lung capacity, the longer you get to aim before your own body's need for oxygen interferes and forces you to move.
Here, I found someone else's explanation and technique to handle it. Again, you see that the greater lung capacity one has, the more time this technique gives you.

Step 4: Check your breathing
You’d be surprised how important breathing is for your ability to properly aim your bow. Not only do the breathing affect the stability of your bow, but it also affects your mental state.
But let’s focus on the bow stability. If you’ve anchored the bow and trying to aim while breathing normally, you’ll see that your bow is much harder to hold steadily.
There is a correct way to breathe that’ll eliminate this issue. Between raising your bow and until you’re at full draw, you’ll breathe normally from your diaphragm. At full draw, you’ll breath out to around 50% of the air, and then hold your breath until the follow-through. Let the air out slowly when following through.
By holding your breath you’ll eliminate the inherent instability your breath introduces to your bow. You’ll be able to aim the bow much better.
If you take too long to aim, you can take a small break, breathe normally to relax, then begin holding your breath again and continue aiming.
Mastring breathing will increase your stability and overall performance.
