I couldnt find much on ST on this topic.
I read this in connection with this. Has anybody have any experience with Respibelt? I cannot find any decent users’ reviews on the internet.
What’s the overall opinion of ST on inspiratory muscle training?
Why shouldn’t the principles and benefits of training also apply to the muscles of breathing? Ventilatory muscle fatigue may contribute to general fatigue during prolonged endurance events. My breathing reserve during hill workouts always seems better after several days of SCUBA diving (higher airway resistance). Don’t know any specifics about the gadget.

Well for one, ventilation and pulmonary respiration appear to only limit performance in some isolated circumstances (e.g. at extreme altitudes) or with disease conditions in which a significant amount of the lung has been destroyed (COPD) or the airways are blocked (COPD or asthma).
Lungs are considerably over built in respect to endurance performance needs.

Respiratory muscle training (RMT) can also improve performance in healthy persons, including athletes. Don’t confuse laboratory testing for VO2max and endurance performance.

I was just answering his question 
I’m aware some studies show improvement in performance, some don’t. Like many of these sorts of things, appears to depend on the population examined, type of assessment, etc.
I feel it has the potential to improve performance for swimmers, maybe, but I just don’t believe at triathlon paces it makes a difference.
exactly.
there is normally no need for isolated inspiratory and expiatory training.

Interesting. Data?
I hope you’re not looking for data that the lungs are not the limiting factor in endurance performance

Not sure what you mean by “need” for RMT. According to a 2012 systematic review of 46 studies: “RMT improves endurance exercise performance in healthy individuals with greater improvements in less fit individuals and in sports of longer durations.” http://www.ncbi.nlm.nih.gov/pubmed/22765281
For decades, exercise physiology textbooks have downplayed the role of pulmonary function in endurance (especially ultraendurance) performance. Accumulating evidence indicates that pulmonary work is significant in long events and respiratory muscle fatigue is real. Apparently, training with breathing resistance is something to consider.
But think about that statement, saying strength training with these devices improves the endurance capabilities of respiratory muscles is the same as saying strength training improves endurance performance when we know it doesn’t, why, because it does nothing to affect the mitochondria which is the source of endurance capabilities.
Thanks for the good laugh. 30 some years later and the crazy Cuban is still at it. Back up the clock, way back and I mean way back. I am riding along the River Road near Baton Rouge, just South of the LSU Athletic complex somewhere in the late 70s or early 80s. Low and behold here comes this guy with a plexiglass tank on his back and a scuba like hose on his mouth, clipping along at about a 6 min or less per mile run pace. Wait,I recognize this guy, it is Alberto hisself Salazar. I talked with him on the LSU track and he said is a hypoxic trainer, forcing you to breath lower oxygen (used) air in a rebreather fashion.
You guys been seeing his Hydro running? Now he has the belt. That guy has just about tried every toy ever made to get faster . He won the NCAAs later that year on the very track if my mind still serves me. I love Alberto and he is a very proven coach way back to the Athletics West days. The guy is brilliant, but not all of what he swears by works all the time.
I am just saying that the applied physiology of these devices should be further explored.
Focusing only on the respiratory muscles, wouldn’t an increase in strength reduce the percentage of their maximal capacity utilized and thus RQ, thereby improving endurance? SCUBA divers have higher respiratory muscle strength and endurance than fitness-matched controls.
I agree, explore all you want, and I think if you are a sprint swimmer or an elite middle distance athlete you may see a very small benefit, but the oxygen saving are quite small, even by the persons standard who was mentioned in the article. She said 10-15 percent at max effort, so more like 7 percent at sub threshold levels. Take the 1 percent improvement she indicates and that’s not even a tenth of one percent more oxygen, probably would take extremely sophisticated equipment to even detect the difference.
I hope you’re not looking for data that the lungs are not the limiting factor in endurance performance
Why not? Where’s the data?
Because at any intensity you still exhale oxygen that your body was unable to utilize, there is an abundance of it because your lungs have an absolutely enormous surface area through which oxygen can diffuse into the blood stream.
If you had only 1 lung though, you may in trouble, it’s probably just redundancy like your kidneys

Conjecture is not equal to data. We base reality on data, not conjecture.
A friend of mine is an exercise physiologist that does VO2max testing on dozens of athletes per week. Testing of athletes he’s done indicates that well-trained cyclists that take up wind instrument players increase their VO2max. The numbers don’t lie.
The statement on exhaling oxygen is not conjecture, it’s a simple fact. If you believe in your data then get a methodology and publish a paper, but I guarantee it will contradict studies which hope to prove the same thing. Isolating for one variable is extremely difficult, I don’t care if you think they help but it makes no sense why a person could utilize more oxygen with stronger respiratory muscles, there is already plenty of oxygen there. The difference in vo2 max values occurs because of how efficiently we use the oxygen, we all take in the same breath.
My friend will eventually publish (that project is not his current first priority). When he does, I’ll post it on ST.
You’ve alluded to data, but still not provided any. Where’s your data?
Ok here is some data. Oxygen consumption does not go up in individuals exercising in o2 concentrations above 21 percent going to 100 percent. Like I said, your lungs already deliver plenty if oxygen, yet you can’t utilize it all, it’s the whole nature of vo2 max, how much oxygen can you use. You can ask your friend how much oxygen his subjects are using, it will be much less than they are actually breathing in.
