Ever wondered how breathing exercises can help those with long-term health issues? A recent look into different studies found that working our breathing muscles through something called "voluntary isocapnic hyperpnoea" can be a safe and helpful tool for patients with chronic diseases. This wasn't a fancy new experiment but a careful review of what's already been done. The studies came from various places like PubMed, Google Scholar, and even the Cochrane Library. They found 12 studies with almost 257 people in total. The studies weren't always alike, and some had missing details or weren't blinded properly, which makes the results a bit uncertain.

The good news is, these breathing exercises seem to help patients endure more when it comes to breathing. Picture this: you're climbing stairs, and you don't feel out of breath as quickly as before. However, it's not clear yet if these exercises also help improve the amount of oxygen you can use during exercise, boost your peak work rate, increase how far you can walk in 6 minutes, or ease feelings of breathlessness and tiredness.

So, while we know breathing exercises can improve respiratory endurance, we're still figuring out who benefits the most and exactly how it works. More high-quality studies are needed to answer these questions and to understand if these exercises work best on their own or as an extra part of regular lung rehab programs.
