A long term effect of exercise on the heart is that it can have a lower resting heart rate (known as Bradycardia). Why is this?

It’s weaker and so it pumps less times a minute
B
It’s weaker so pumps less blood each beat, meaning it needs to beat more times a minute
C
It’s stronger and therefore pumps more times a minute
D
It’s stronger so pumps more blood each beat, meaning it does need to beat as much
Explanation: 

Detailed explanation-1: -People who regularly exercise can have bradycardia because they are in good physical shape. Bradycardia doesn’t affect these people because their heart pumps blood more efficiently and meets their body’s needs even though it beats slower.

Detailed explanation-2: -Bradycardia is normal for some people, especially if you’re extremely fit. However, it can also be caused by: damage to your heart due to aging or heart diseases (such as heart attack), cardiomyopathy or myocarditis. hypothyroidism.

Detailed explanation-3: -Also, your body’s hormonal state (adrenaline) and recovery processes keep your heart rate up for several hours after training. If your RHR is elevated, your body could be in a state of overtraining due to too much training and too little recovery.
