Proof?
Here ya go. Here are 6 case studies. All dealing with eurupean socer. If you google there are hundreds of studies in the last 20 years why European soccer players are dying of heart attacks and more every year.
The basic gist or common element is most soccer players are from very poor countries such as East Africa which has a very high history of genetic family heart issues and they are very hard to diagnose. It takes very specialized test which most people do not have done or do not have the capability to have done Kosovo and Serbia was another area where many soccer players come from to play in Europe with large genetic family issues of the heart
So the question is why are not American sports players dying of heart attacks like soccer players? I have not seen a single AMERICAN football, baseball or basketball play die on national tv of a heart attack in the last 2 years during covid? Have you?

Soccer and Sudden Cardiac Death in Young Competitive Athletes: A Review (hindawi.com)
If you do not understand the difference in activity levels in players of soccer as compared to baseball and football where they are sitting or standing around 90% of the time... it illustrates only your extreme willful ignorance.
Even basketball does not compare to soccer when it comes to a cardiovascular workout. “Soccer players run 2.5 times the distance of a basketball player at about double the speed.” “On average, soccer players run about 7 miles per game, and some players run upwards of 10 miles in a single game. Covering this much of the field at staggering speeds of up to 20 mph in World Cup play with no time-outs”.

So stop quoting idiotic theories and acting like an ignorant fool... it is unbecoming.
