Why would you think higher heart rate is good? it's bad. Efficient heart will work slow 50-60 bpm. 95 to me looks insanely huge number, unless you was running at that time In fact i feel the apposite effects. Im not saying it's because of MB but now my heart beats less frequently, especially at nights, it feels so efficient and relax. As i was sayin - loooks like i need less oxygen now vs before my MB and acetylsalicylic acid "diet".
Also i would not bring here studies, but i heard that the higher heart rate - the shorter the lifespan. I mean in animals who have high rate, lets say small ones vs those with slower.
Ray says the HR of 70-85 is better. He says that the higher number is stronger, called the "stairstep effect."
Here is verification of that:
http://circres.ahajournals.org/content/58/2/281.full.pdf
"During low levels of exercise, there was a linear increase in cardiac index due to an increase in both heart rate and stroke volume index; stroke volume index increased as a result of an increase in left ventricular filling pressure and end-diastolic volume index and, to a much smaller extent, a decrease in end-systolic volume index."
I think this approximates raising your HR by raising your metabolism. An increase of, say, 15% in HR corresponds to very moderate activity, and this study suggests as Ray has said, that the higher HR means the heart beats "stronger" than it does with a slower heartbeat.
