Physiology: TPR and the diastolic pressure

[Akam ahz]

Hello,

I came across this line in my text book:
"Total peripheral resistance (TPR) increases diastolic pressure more than systolic pressure."

I don't understand how the peripheral resistance would increase the diastolic pressure more than the systolic pressure?

Could some one explain that for me?

Thanks!

Just a hypothesis, but

Im assuming it's because even though systolic rises, diastolic has a greater change since the atria are weaker than the ventricles and thus need to increase force by a greater amt to increase output

to increase output

Increase the output?!
But in diastole there is no output, the heart is filling, right?

Actually, I don't get your point :/
Could you clarify more?!
