| Re: Heart rate with cardio. Fat Burn vs. Cardio Training
In response to the original question of this post:
As a rule of thumb, a lower resting heart rate means that you are healthier.
The heart pumps blood because it transports the oxygen and nutrients that every cell in your body needs. (It also takes out the waste from the cells.)
If your cells are oxygen-deprived or starving for nutrients (i.e. you're unhealthy), then it will demand more blood to deliver more fuel/food - thus a faster resting rate.
As you exercise and require energy, the cells convert the fuel into actual energy to enable you to run, and lift, and swim, etc. etc.
Naturally, this increases the need for more fuel, thus your heart rate increases. As you stop exercising, your body's energy consumption decreases accordingly.
As a rule of thumb, you should focus on how fast you recover.
In order words, how long does it take to go from your high intensity heart rate down to your normal resting rate?
The faster you are able to recover, the healthier you are. (for example, your arteries are NOT clogged, thus requiring less pumping to transport the blood.) |
