In some endurance athletics, I've read some coaches use a training technique where you hold your breathe for brief periods during the workout. For example, if you're running, you may hold your breath for 50-100 m, while maintaining a constant pace before, during and after. The 'theory' is that the normal working CO2 level in the blood stream is significantly lower than what the body can tolerate, and this training resets the system to tolerate a slightly higher CO2 level. Since breathing is mainly driven by this CO2 sensing mechanism (strictly speaking, blood pH), it decreases the desire the breathe, which is using up a significant part of your effort in an endurance event. In 'theory' in the long term, something similar might have an effect diving, although with the relatively low exertion levels during most of a dive, any effects would probably be small.
On the other hand, a lot of coaching techniques seem to rely on voodoo and techniques not really proven in any scientific manner, so this could just as likely be just a lot of hot air.
I am learning to improve my breath holding ability for free diving and was wondering if it will have an effect on my Sac rate? before y'all go down a dark rabbit hole, no I am not holding my breath while diving scuba. I breath slow and deep.
With a little practice I was able to improve my breath hold duration from one minute to three, not much changed this was one hour of practice. I am considering what effect it will have on Sac. if any if I continue to practice.
would it be any benefit to practice breath holding before a dive? reduce heart rate, relax etc, however increase blood CO2? good? Bad? how long is this effect? is one longer than the other?
