FAA changes EKG paramaters?
An interesting perspective, I cannot speak to it though as I'm not a medical professional:

Sorry the guy’s wife had a heart problem but HIS findings aren’t uncommon in endurance athletes.
Steve, I am a 66 yr old commercial aviator with no previous heart problems. On Jan 6, my first class medical was deferred, due to 2nd AB block, Mobitz type 2 (see picture of EKG with diagnosis). I am asymptomatic.
I received both Moderna injections (March&April 2021). No booster.
I am an ex endurance athlete (road bike racer) and do not and have not taken any routine medication)
I’m awaiting an appointment with. Cardiologist next week.

33/66 (50%) of the athletes were undertaking endurance training while the other 33 (50%) were involved in a strength-training regimen. Overall 54/66 (81%) sportsmen had significant ECG changes. 68% of these changes were considered as normal training related features, while the remaining 32% were considered abnormal. There were seven common training related ECG changes–Sinus Bradycardia (21%), Sinus Arrhythmia (16%), 1st degree Atrioventricular Heart Block (6%), Type 1 2nd-degree Atrioventicular Heart Block (3%), Incomplete Right bundle branch block (RBBB) (24%), Early Repolarization (42%), Left Ventricular Hypertrophy (LVH) (14%); while three abnormal ECG changes--T-wave inversion (13%), RBBB(4%), Right ventricular hypertrophy (RVH) with strain (29%) were noted. Early repolarization (commonest change), sinus bradycardia, and incomplete RBBB were the commoner features noticed, with a significantly higher presence in the endurance trained athletes.

Conclusion
A high proportion of athletes undergoing competitive level sports training are likely to have abnormal ECG recordings. Majority of these are benign, and related to the physiological adaptation to the extreme levels of exertion. These changes are commoner during endurance training (running) than strength training (weightlifting).Keywords: Electrocardiography, Endurance training, Strength training, Sports cardiology, Competitive sports training

Manifestations of Increased Vagal Tone
Sinus bradycardia, prolonged PR interval, and Wenckebach phenomenon are common in athletes as a result of the high resting vagal tone, or significantly lower intrinsic heart rates.23Authors' Recommendation
We do not recommend further evaluation for any degree of QRS voltage as long as it is isolated (ie, there are no other findings and it is associated with normal axis, acceptable repolarization, and normal atrial activation). Similarly, we do not recommend further evaluation for sinus bradycardia as low as 30 bpm (with sinus arrhythmia, some RR intervals could be prolonged to 3 seconds) or isolated early repolarization. A prolonged PR interval up to 300 ms should not prompt further workup, but longer intervals should be resolved with an exercise test (the PR interval should shorten as vagal tone is withdrawn). Similarly, Wenckebach phenomenon in isolation need not prompt further work up, but an exercise test could resolve any concern.Comparison With European Society of Cardiology Document
These recommendations are in line with those of the ESC.https://www.ahajournals.org/doi/10.1...aha.110.013078

Word to the wise for you hard-core endurance athletes: As you get into your 40's start respecting your textbook max heart-rate.
- Keep your cardio mostly in the green/yellow zone.
- Limit red/max HR to intervals of a minute or two tops.
- Don't push intervals much beyond your max HR.
If you really want to compete seriously, go get a treadmill test to baseline your *actual* max HR (which does vary by individual) and then respect that. It will probably be higher than the theoretical age-derived max, if you were a decent athlete in your youth.

RE: exercise in general
every hard core max endurance athlete I know, has had hip replacements, knee replacements, and other issues. once guy almost died in the middle of a race because blood levels got all jacked up and he went to the ER in an ambulance.
no thanks.
I will do my gentle old-man jog and mostly walking during the week coupled with smart eating, lots of water, and controlling external stress in my life.

I agree that serious extreme is bad as you get older.
But it is now known and accepted that for knees and hips especially, regular exercise actually strengthens cartilage... the impact stimulates growth. That's basically for running and hiking, as well as lifts like squats and deadlifts, ie the natural movement for which your body evolved. Activities like tennis, basketball, etc which involve a lot of side-loading are more likely to be problematic. But running and weights can and will offset that, by keeping the cartilage healthy to begin with (I still ski moguls, just not constantly). I keep it moderate but I still run 3-6 miles 2-3 times/week and do the weights.
And yes watch the electrolytes, eat bananas or some kind of supplements, most especially when it's hot out. The more you sweat and drink, the more you need electrolytes. We had two 50-ish CA's keel over dead while exercising vigorously. Both were fit endurance athletes who lived and exercised in the desert and I'm reasonably sure they both let their electrolytes get out of whack doing daily exercise in the summer heat. You sweat out electrolytes, but you don't replace them when you drink gallons of water.

I am all about that
but Triathlons, ocean swims, etc. I ain't doing it

Doing an Iron-man probably won't wear you out, but consistently training to that level might. I mostly do sprint tris any more, but I'm pretty sure I could train for olympic distance without any issues. More a matter of time, job, family, etc.
My suspicion is that most knee and hip issues result from injuries incurred while young, aggravated by lack of exercise as you get older. I had plenty of injuries, worked through them and stayed active. Glucosamine helps a lot, apparently it works great for some, not so much for others. It's great for me.
