#69 - The heart and exercise: Should middle-aged men pull on lycra? With Dr Andre La Gerche

Рет қаралды 3,249

Күн бұрын

Dr Glenn McConell chats with Associate Professor Andre La Gerche a world leading Sports Cardiologist from St Vincent’s Institute of Medical Research, Melbourne, Australia. Andre is a very big advocate of exercise and recently won the over 50 category at the Melbourne Marathon (running 2:36). However, acute exercise for long periods at a high intensity can result in abnormal right ventricle function. In addition, years of long, hard exercise training is associated with increased coronary artery calcium (CAC) levels and atrial fibrillation (AF). Despite this, again, Andre recommends exercise across the population and generally even in these individuals. The evidence is that exercise training increase healthspan and reduces mortality rates despite some of these changes. A very important, interesting, long chat. Twitter: @@ALaGerche

Excellent insights clearly explained...particularly the paradoxical aspects of calcium burden and exercise , and many other topics.

Thank you! May I say, this is the best channel for those of us who are interested in exercise from a more scientific angle. This channel deserves a ton more subs - and it will happen in time.

I only recently discovered your channel and find it very informative, pertinent and beneficial for our overall healthspan and well-being. This was one of the more "accessible" and broadly appealing episodes with an affable guest who was articulate, unambiguous and educational, facilitated by your own knowledge and genuine interest! I'm a mature-age runner and cyclist and just completed the Melbourne half-marathon. Exercise is a necessity, not a luxury! Cheers from Melbourne.

Ive always wondered if it's not the actual exercise that's causing calcium buildup but the sugar gels bikers and runners consume. Sugar is said to cause inflammation and the calcium is the "scab" that moves in to heal it (as stated in this video) but it takes years/decades. My aorta calcium has DECREASED since getting serious about exercising in the form of trail running and hiking 5 days a week on a KETO diet. I'm 68 years old and I have only one kidney as I lost the other one to cancer 12 years ago. I have not had a CAC scan but Ive had a LOT of regular CT scans because of the cancer and you can see the calcium in the artery but is less now after 5 years of endurance exercise hiking 20 miles a day. I have never taken a statin but all my doctors have tried talking me into taking a statin but I just tell them I wont take a drug like that just to chase a small statistic when it's known that just as many people have heart disease with good lipid profiles. There just too much to this topic that can probably be covered here but exercise improves the lipid profile but not by lowering colesterol but raising HDL and lowering *oxidated* and *glycated* LDL (healthier, younger lipids so to speak) Have you heard of Dave Feldman and the *"lean mass hyper responder"* studies that have just come out recently? Speaking of inflamation . . . I do have exercise induced vasculitis that shows up on the calves when I do 20 miles on a hot day but when I'm backpacking 20 miles a day EVERY day then I dont get it. I wish I knew why that was but vasculitis is an autoamune condition. It maybe can cause the artery blockage spoken of @34:14 . . . corticosteroid have no affect on my vasculitis but I was wondering if s statin would help but I read that they do not reduce vasculitis.

I have had afib but it wasn't due endurance exercise but rather mitral valve regurgitation which changed the shape of the atria. The changed shape or remodeling is believed to have set off the afib, which was quite severe. Severe means experiencing bpm from 60 to 200 within seconds and back down again. It was way more than uncomfortable but downright hazardous in terms of stroke risk. I have always been an amateur cyclist and that gave me the reserve to survive open heart surgery to fix the mitral valve and afib.

Amazing talk! Learnt a ton. Would have loved to hear if HRV is a good measurement of cardiac recovery. My big take away is duration * intensity is the dose. Training easy miles you can likely do more than 6 hours a week but if you compete the intensities required to do so will limit duration for optimal health

I feel like this is a good place to make this comment. A decade ago, a loved one went to hospital with angina, he was in advanced age, calcified coronaries 70%, and the doctor said we have to stent. This person died during the stent procedure, as a risky maneuver was used to get past the calcification. After the event, I poured over the literature and discussed with other doctors who agreed he should've never been touched. The angina was not frequent enough nor debilitating enough to justify stents which had almost no evidence of increasing longevity for this particular demographic. The doctor who did the procedure built his reputation on preventing heart surgery, at a prestigious hospital whose initials are C.S. in California. You have to be your own advocate. Listen to these two discussing and make better medical decisions. Not all doctors are bad, but there are enough to do irreparable harm. Get second and third opinions. Not medical advice, just common sense.

I found this a really informative podcast. Being a well trained athlete and having just had a heart attack, I've been wondering to what degree exercise might have contributed to the problem. I have one burning question for Andre - is there any link between endurance training and the development of Coronary Artery Ectasia?

I recently read the book “Up to speed” by Christine Yu about women and sport. Perhaps you’d cover this topic at some point. Louise Burke from Australian Catholic University and Anthony Hackney from University of North Carolina seem pretty interesting 😇😇

@insideexercise 8 ай бұрын

Thanks. I’ve had two episodes about exercise physiology in women (episode 11 and 35) and also I’ve had Louise Burke on talking about sports nutrition (episode 7). Anthony Hackney unfortunately declined my offer to come in the podcast. I will indeed have more women in sport episodes. Thanks again.

Yes indeed. I’ll definitely have more specifically on that women and sport/exercise. I have two booked in actually. The podcast episode with a Louise Burke wasn’t specifically on women. These two are: episode 11 and 35.
