![]() One-Side Breathing
When breathing on one side, I understand you have to inhale from the mouth, and immediately exhale from the nose until the next air breath. What about Bilateral breathing? I. Which one is the correct cycle: a. Inhale, hold, hold, exhale-inhale (get rid of the CO2 at the end) b. Inhale, exhale, exhale, exhale-inhale (progressively get rid of the CO2) I ask because a Coach previously suggested to do a. in order to float better (holding air in the lungs for longer before exhaling). It seems strange because that would mean storing CO2 II. Proportion INHALE vs EXHALE in Bilateral breathing If the "Inhale part" takes 1 unit of time (T=1), how long is the recommended "EXHALE part"? Assuming cruise speed for 1 Mile (35min) III. Swimming vs. Jogging Comparing a "Jog" and a "cruise speed long distance swim". Assuming a Heart rate of 120 for both... Would breathing be the same? Or would Swim require a different type of breathing ? Thanks. ALEX Last edited by Alex-SG : 08-06-2009 at 07:32 PM. |

![]() Good luck with the 150 bpm for jogging. I routinely average 155-165 when I run and I'm not even that fast. My resting heart rate is about 45 so its not that I'm not in condition. When I was training for my last marathon, one of the coaches suggested that a more disciplined "deep breathing" would be more effective for us. So I think highly trained runners may breathe more like a good swimmer. But my guess is that there is a world of difference between the way the average runner and the average swimmer breathe. What keeps me refining my technique as opposed to swimming relatively long distances with bad form is that I cannot handle the oxygen requirements of swimming badly. I see a lot of people that can but I'm not one of them. So I constantly try to fine tune my technique so that one day the oxygen that I am able to supply will fuel my swimming for whatever distance or time that I choose to do.

![]() Let's simplify all this . When your face is in the water you emphasize the exhale steadily from the nose and keep your lips slightly parted which means some air is also going to come out of the mouth .You exhale the last bit as you roll to the air and then you inhale through the mouth until the exact second that your face returns to the water and do it over again .

Personally I just exhale slowly as long as my face is submerged and just before when I'm about to take a breath I let everything out so my mouth is clear from water. So that's about 80% out slowly and then the rest of the 20% out quickly. |

![]() I am trying to figure out the best breathing pattern for myself as well. Logic seems to imply that holding the breath and exhaling before the turn to air is the best option, because it keeps the most air in the lungs so that the most CO2 can diffuse into the air in the lungs and the most O2 can go from the air into the blood. If you start exhaling immediately after inhaling, the average amount of air in the lungs is smaller, therefore its capacity to take up CO2 from the blood vessels and to give a large amount of O2 to the blood vessels is reduced. This comes on top of the fact that one floats less well.
However, I have heard the advice to start exhaling immediately so often that I think there must be some good reason for it. Then again, I am by no means an expert and just starting to learn myself. |

![]() ".....the most CO2 can diffuse into the air in the lungs and the most O2 can go from the air into the blood...."
There is not a significant enough difference in this scenario to justify it. It is the respiratory rate that has an effect, not the lung inflation. Holding your breath creates tension in the chest which is your core. The pressure this creates also increases your heart rate needlessly. On the other hand, forceful exhalation can cause the same problems. The best way to do it is to gently exhale in between inhales. You will usually have some excess air before you inhale so you can gently "dump" that air without trying to excessively "squeeze" all the air out of your lungs. In general, it seems to me that the best breathing is to match the type of breathing you have as you take a brisk walk -- more active than if you were sitting down but taking nice lungfuls of air without forcing it in or out.

![]() madvet, are you sure this is insignificant? The amount of o2 one take up and CO2 one can get rid of per breath must be correlated somehow to the avg. amount of air inside the lung during the breath, no? That's why lung volume is not umimportant.
I agree that the tension this causes might negate any positive effect. But I have not determined yet if this is actually the case. |
