What changes take place?

Hi guys - I just have a general query about freediving and apnea training.

When you lift weights, you destroy muscle fibres, that grow back bigger next time, which is why they grow.

When you run, you increase the strength of your heart, making it better at distributing O2 around the body, meaning you can run longer etc

But what happens in your body when you're doing your apnea training that means you can hold your breath for longer next time? I can't think of anything!

Thanks

Hi ironic,not sure of the science bit but basicly you are training your body to tolerate the higher levels of co2 and lower levels of o2 starting out the body is not used to the situation but with training grows used to it. Also the blood thickens with time training and allows better "gaseous exchange or o2 bonding cant remember if thats right but its a long that line i think. The body also adapts with the dive reflex moving blood from the peripheries and shifting it to the core heart lungs and brain.

Ah I see! I knew about the dive reflex, but didnt know the blood thickens with the training, that's so cool!
