QuoteKen I guess this should be obvious, and if so I missed it. Is the study correlating a short period of high MET activity (a few weeks or daily) to initiating an particular afib episode? Or is the correlation between those individuals with years of high MET activity (athletes) being more susceptible to afib during their lifetime? My interpretation is it is lifetime. From the studyby GeorgeN - AFIBBERS FORUM
QuoteKen There seems to be two issues. One, the paper doesn't define "remodeling with intense exercise"., In other words, what is intense and for how long. It assume that athletes that trained at a very high level for years are more susceptible to afib than normal people. I am one of those and maybe that explains why am here sharing information. But what about the recreationalby GeorgeN - AFIBBERS FORUM
As the paper that PC links in his post in the thread below this one notes, exercise helps most people with afib. However those, especially males, who are at the far end of the intensity/volume spectrum can be damaged by exercise. As I've posted before, for me the trigger is the product of intensity times duration. I've found that limiting my intensity on exercise sessions of longerby GeorgeN - AFIBBERS FORUM

I'm a big fan of vitamin D and of doing things that reduce TNF-α (for example, my doc, Gundry's, clinical experience is that eliminating foods high in lectins that humans are sensitive to will reduce TNF-α). However, from PC's link. "On the other hand, intense physical activity can produce adverse remodelling consequences that increase AF risk. Intense endurance trainiby GeorgeN - AFIBBERS FORUM
Thanks PC! As I've posted, Dr. Gundry likes our 25(OH)D levels high - around 100 ng/mL. He also tests TNF-α. My last value in Nov 2019 was 1.9 pg/mL (goal <3.0). I've been an advocate of moderating exercise as I've previously posted. Here is resized version of your graph below.

I don't make too much of it. Magnesium has to be really low to get a low serum value. Same with calcium, high or low. Potassium varies all the time. They sampled once and then looked at outcomes over 20 years. Also, they were average age 44 at sample time. Unless athletes, would not expect afib in this group.by GeorgeN - AFIBBERS FORUM
