Hello, I’m new to the forum and your post encouraged me to reply.
My advice is to come back to fitness very slowly from covid. There is still a lot of unknowns about the disease, particularly for very fit people. Those who aren’t doctors don’t understand the research developments and will not know that it is now known that repeated covid infection is very bad for us athletes.
I’m a coach originally from England but now based in France. I can see the issues and negative impact in those I coach from their heart rate and also myself, with HRV, and power output across sports decreased. The impact gets worse with each covid reinfection.
What you describe is normal for 1 in 5 to 1 in 10 covid patients, normal post covid or longcovid effects, with very mild or mild covid illness. If you experience reduced lung capacity for more than 12 weeks in the UK this is then called longcovid. You are experiencing endothelial damage. My job means I’m vaccinated and have had 5 MRNA vaccines. They work to reduce the severity, but like you this time round I have extended reduced lung capacity and issues resuming my normal triathlon activities. I’m 41 years old.
If you are a triathlete you should be aware of the issues on your health regarding repeat covid infection.
Do not rely on a single study for information, rely on scientists who translate study of studies and summarise those studies. In the UK doctor cardiologist Rae Duncan provides useful summaries of covid19. She’s the national health service UK longcovid clinic director. The damage even very mild infection does is now obvious, including in children, which is worrying. Repeated infection year after year is having negative effects in athletes. You can prove her credentials by googling her.
The new evidence is that covid reinfection causes damage to accumulate with each infection. Any infected person has a raised of cardiovascular complications and heart problems for 12 to 24 months after infection. If you are catching covid twice a year, you can see why this is going to cause untold damage as you age, your risk factor rockets upwards even if you are a very healthy individual. Covid is S.A.R.S, severe acute respiratory syndrome. You are repeatedly infecting yourself with S.A.R.S and it is now known that this is not good for long term health, as was always obvious to us medics.
Here she describes the endothelial damage seen even in mild covid patients:

Here is the effect on children from repeat infection, which is my concern for the teenagers I coach:

I’ve just noticed she was on the BBC trying to raise awareness of the new developments in covid research which shows repeat infection is actually bad for us. It isn’t a cold, after all:

The US and Canada covid19 lead researcher is Ziyad Al-Aly, if you want to read scientific papers on covid his research unit is a good place to start. Canada, UK, and USA are leading the way with covid research.

People will open up if you speak to them one-on-one about the effect covid infection has had on them. You don’t need to always ask, because you can see it in their strava stats. People blame it on ageing and other factors, but if you have had covid repeatedly you will eventually notice the endothelial damage on your cardiovascular system even if you have no symptoms during infection or had a very mild infection. This is why you are struggling to feel as if you have full oxygenation. It appears in one third to one quarter of mild infections, so it is very common.
Is it healthy? Of course not. Trust how you feel, not how people tell you to feel. I wish you a speedy recovery.
