So i’m talking to a friend of mine tonight, regarding my current workout program. I was explaining JB’s TMA Routine to him, and was explaining HIIT to him and the intervals etc.
Anyway, he says that according to his “doctor” High intensity training above 65% of your max heart rate will damage your heart valves.
I politely disagreed, and didn’t really argue too much, since he seemed convinced. I then proceeded and changed the topic.
So I hit google, and couldn’t find any valid sources of this type of claim.
So if you let your heart rate go above 65% it damages the heart. I think he heard wrong.
Even doctors would be so narrow minded…would they?[/quote]
The more likely situation, one I see every single day, is that the patient either heard wrong (ie. what they wanted to hear) or they completely misunderstood what was said. I have literally been in the room when a previous doctor last spoke with a patient only to have them see me at a later date and tell me they were not told what the appointment was for.
They tell us that patients only assimilate about 20% of what they hear. I think it is probably less than that. I repeat things often only because I have the luxury of more time. I can imagine that civilian practices just don’t have the time to repeat this info 300 times for each patient to make up for this.
