I'm a physiologist, not a physiotherapist. These are two very different roles. As a physiologist, I am a scientist who works with people performing measurements to assess bodily function, for me, the cardiopulmonary system. I work mainly in clinical research in a exercise lab and have extensive experience testing older adults in clinical cardiac testing. When I previously worked on the clinical cardiac side, I was the person who performed and interpreted the results of your cardiac or pulmonary stress tests prior to them being sent to a physician. Cardiac stress testing In a clinical cardiac environment 85% of max HR is considered to be diagnostic and where we'd typically expect to see heart abnormalities to make themselves known. In the clinic that I previously worked at, our cardiologists did allow tests to continue the testing past 85% to see if any abnormalities did manifest at a higher HR. Again, this only happened because it was in a clinical environment where the patient would be safe even if things happened to go sideways. But, I'm not a fan of pushing older adults beyond 85% without having them hooked up to an EKG and having a clinical support staff for patient safety. VO2max testing To the average person VO2max is great at telling us about your overall health, because you're looking at the bodies ability to consume oxygen and produce energy. Most people aren't getting a VO2max for anything besides seeing a big number (me included), and that's obviously okay too! On the measurement side, VO2max is the max sustainable amount of O2 that your body can consume during a maximal effort. If your bodies ability to consume oxygen is impaired (low VO2) it may suggest a wide variety of issues such as reduced mitochondrial health (number, size, mutations, etc), impaired gas exchange or ventilation, reduced cardiac output, or a ton of other issues. During VO2max testing we are only getting into the what is happening by measuring VO2, and not the why, as that's a different type and part of testing. Is there a point of VO2max testing? In general I think testing and screening gives some peace of mind that everything is working as it should. In the small chance that you do have an issue, like an undiagnosed asthma, testing is one step that can lead you to being healthier and stronger in the long run. Quote:

You'd have to chat with your cardiologist to determine whether it's reasonable or safe to continue to a higher HR during testing. At the end of the day, a lot of these things are about liability, and the Dr. is the person to make those decisions since they'll be the person accepting responsibility if anything were to happen.

This type of perspective alone would send me running in the opposite direction. I'd do some more digging, but there's essentially no information on their website describing anyones background at the company to justify why this type of testing is important. Lots of the information is lacking specificity, and in general isn't satisfactory in my opinion. https://www.dexafit.com/faq Quote:

UMass Amherst UMass Boston UNH Tufts Springfield College Some programs will offer testing for a fee if done outside of a research study, but sometimes there'll be a research study if you're lucky that'll have testing as a component. Not as convenient as going whenever you want, but you'll be working with a team whose main concern is getting the most accurate information possible. Last edited by mjf; 04-13-2024 at 10:50 PM. |

It’s generally frowned upon to trigger an arrhythmia and not be able to do something about it. I doubt they were acls trained or had a crash cart handy.
Pretty wild if you’re testing older athletes. Not common for endurance athletes to develop afib, though that’s usually an issue when your RHR lives on the super low end iirc. I think lactate threshold HR is a more useful metric for older endurance athletes. I doubt you spend as much time in your VO2max range on the bike since it’s way more taxing and will hinder recovery. Anyway. Not my area of expertise etc etc. Last edited by ridethecliche; 04-14-2024 at 01:16 PM. |

I know GCN, however he is doing it to, you might find his testing and progress interesting. https://www.youtube.com/watch?v=YIEjavvzCfU
