I mean it's the look alone that could tell

Triumphant music in the background 😂

can someone give me the short and tall of this in about a paragraph or so please... 28 minutes long and i can't be bothered to watch it all !!!

As a retired 80 year old scientist and former competitive rower, with over 34,000 citations, let me say that I found this talk to be absolutely superb, brilliant! I feel like I learned a tremendous amount from this.l Thank you so much, Dr. Baggish!

Since I got the JJ vax,I’ve been having pain in the side of my stomach. What could it be?

Dude, why are you talking so fast? It's too much information as a passive listener. Slow down, take a deep breath and let the listener write things down. Not criticizing your content,just delivery.

I cried watching this

Always refreshing to see a presentation by someone who is clearly extremely competent.

I’m 66yo, not sure I qualify as an “endurance athlete”, zone 2 trail run 6k/day/365 added CrossFit 3d/week (for BD and sarcopenia) plant based, I keep apoB<45 (ldlc low 30’s) [baby statin] in the hope of keeping arteries clear.. ct.a showed cac:0, “no vessel disease”. I am worried about afib, “slightly” dilated LA .. but oh well, I’ll keep'it “slow” … for me .. exercise upregulates BDNF / klotho …

Great talk!!!

Jim Fixx, take note.

So, couch potato 🥔 is much healthier. 😊

Exercise doesn't actually pass the tests you put it to. Rather, it fails pretty much all them, but with plausible explanations. There are also things like AFIB and stenosis, where you actually concede. Are the data all in? No. Certainly eight crazy people aren't going to take us far, and the kinds of controlled experiments required for proof can probably never be done. This is just to point out that you are an apologist for exercise, and we viewers must take that bias into account.

Only light excercise is for human

Human body is not designed for hard work human is known because of brain so physical excercise is for animals

BRILLIANT Talk. FIRST TIME EVER that I really nicely understand WPW and it's role in sports medicine

Would be interesting to learn whether some of these people tend to revert to sinus rhythm during exercise "warmup" and whether their performance is impaired or not as to competitive level My impression is that when and if atrial fibrillation has become persistent into exercise then the level of performance drops very severely. (As to the oxygen intake or "mets" that can be sustained during running or even whether anything more than a feeble slow jog at a high perceived effort level can be attained.

Great summary, should be over emphasized in low resource settings where even in professional leagues the AED remains luxury

With regards to the personable Ryan Shay another name also comes to mind (death/drowned in the pool,possibly had a genetic cause for a "right ventricular dysplasia"? (Same thing that the now late John C. Bogle had his heart transplant to remediate (?),he went on to live for many more years) : Tate Ramsden ? College Varsity Swimmer Was he intending to study for a career working at somewhere like Vanguard? (John C. Bogle's financial house)

Circa 23:00 Runners often "carbohydrate load" before a race which might lead to loading up the porta potty and might not be all that good for health. Might even be a sort of abuse of the body (although I don't think runners should skimp on nutrition)

Thanks for your informative sharing👏

I watched this video just now. Will be 80 yr old in 2 weeks. Retired primary care physician in HK. Recently I involve myself in intensive internet searching and reading/studying re: the subjects on endothelial glycocalyx (initially inspired by ESL - Endothelial Surface Layer, and non-osmotic sodium storage in skin). I am not an investigational scientist/academician. I submit that the following SPECULATION might explain, at least in part, the harm caused by "too much" of exercise. I am quite happy with my 22 minutes per day low-to-median intensity jogging fairly consistently (154 minutes/week) - as mentioned in the video at about 6-minute-time. The Glycocalyx is endothelia/vessel protective. In basal/healthy conditions, after 22 minutes' exercise, there would be shedding of the glycocalyx, (proteoglycans/glycoproteins) due to oxidative stress (hopefully my vit C might help as an antioxidant) and others. Regeneration of the glycocalyx in the next 23 hours 38 minutes is assumed to be enough. If one jogs "too much" (duration- and intensity-wise), the body does not have enough time/capability to regenerate all the glycocalyx lost. Remember that the glycocalyx is protective. The rest is self-explanatory. I am certain that there are other factors involved. Recently, I only need to get up once to visit the washroom from 2-3 times (LUTs). Two years ago I took alpha-1 blocker but got occasional extra systoles/with no syncope. Since then, not taking anything except glucosamine OTC and vit C OTC. Lastly thank a million to those medical scientists I came across in the net.

I am a 79 year old (in 2 weeks) retired ER physician and I am a rabid advocate of the health benefits of cycling. It truly works miracles and as an example I can still do 4 minute 19 second on the USAA Cycling 5 minute TT (a 4% average upgrade at 6300 foot elevation in Colorado Springs). I weigh low 170 pounds. I can't believe how good I still feel thanks to cycling BUT one area doctors never discuss (and this is huge) is alcohol and the heart. Alcohol is a potent cardiomyotoxin (meaning it is toxic to the heart muscle and causes heart muscle inflammation) but this is dose related. When I was in training I had a 23 year old die from his excessive alcohol intake causing congestive heart failure. In the ER I would see young people come in with an arrhythmia over the holidays due to excessive alcohol (thus the title "Holiday Heart"). As one gets older the risk of Atrial Fibrillation goes up logarithmically and AF can be exercise induced. AF causation is multifactorial and these precipitators make it much more likely during a ride: dehydration, low potassium, hypothermia (even drinking a smoothie can bring it on!), lack of sleep, too much caffeine, thyroid excess, and others. But no one ever seems to bring up the subject of excessive alcohol prior and the risk of AF. I love a nice red wine and this leaves me conflicted but I have found that half a bottle 2-3 days a week seems to not precipitate AF so one does not need to totally do without. My take home message to all us geriatric cycling advocates is keep all those precipitators to a minimum including alcohol and you can continue to partake of the Fountain of Youth and not need what most doctors would recommend: blood thinners or cardiac ablation! Also, watch your heart monitor (Garmin or whatever) like a hawk and when your rate starts getting in the upper ranges just back off to keep it out of trouble. Very high rate from exertion can bring on AF. AND be sure you are not overweight because any fatty tissue on your body gives off inflammatory cytokines (signaling molecules) which leave you in a chronically inflammed state prone to AF (and cancer). I will add that American physicians are so terrified of lawyers that they make recommendations which are to the serious detriment of their patients. Today I rode 48 miles and climbed 5000 feet and it felt wonderful.

What with incomplete left bundle branch block? Seems not to be integrated in the Seattle criteria..

This is so scary, how do I prevent this?

That's such a great summary

ruclips.net/video/ZK7FdI-vyWY/видео.html&ab_channel=MayoProceedings

They went into V-tach. The seizure like activity they go into, happens every time our patients go into v-tach and is hallmark for it. Definitely cardiac arrest

Never exercising again! Dear God its so scary, scarring and ischemia and what not! I'm better off laying on my couch 😂

You forgot to add never take the booster shots.

Why does this happen, I’m honestly scared I feel their have been a ton of athletes recently

How do you treat pvc of 48

what you forgot is to remind people not to gather around a collapsed person or yanking their heads. I keep seeing this in football. It will only injure the person more.

When you watch this video when you are getting 20 hours a week….. and they give you the guidelines for an hour a week of exercise.

Thanks, can dr Aaron Baggish update this after 5 years.

This compliments the recent work of South Wales Ulster Rugby Supporters Club ❤️🤍🖤💛 #ChainOfSurvival ruclips.net/user/livekL-88QXFP-c?feature=share

MEAT LOAF!

Thanks for putting this together Dr. Drezner. As a former college soccer player and 2x SCA survivor, this is very hard for me to watch but so important for the public to recognize how SCA shows up in sports and how we need to respond with the cardiac chain of survival.

COVID vaccine…. Enough said.

Thanks for creating and sharing this importance message Jon!

Please add: Someone (maybe two or three people) must greet the ambulance so they know exactly where to enter (building, sports complex).

Very interesting lecture, love from Indonesia 🇲🇨

16:30

And maybe the pro CrossFit athletes would also be a good study

Sir I would love for you guys to do a study on UFC Fighters of all ages and backgrounds of health maybe this could help you ,they are hard core endurance athletes .ultimate fighting championship fighting MMA sport

Thank you. I am 70 yo wLVNC and hf and ef of 25% . On all the new heart failure meds and hoping ef comes up. Appreciate your info . Also have some sort of generalized chronic pain syndrome

At 5:13 Dr. Baggish gives exclusions and states a t wave inversion in 3 and aVF does not constitute an abnormal finding. Can someone direct me to more resources or explain this to me in detail?
