How does exercise affect the body?
When we exercise, our muscles become more efficient at consuming oxygen and converting it to useable energy. One of the body’s natural reactions to aerobic stimulation is an increase in oxygen-transporting enzymes, which carry oxygen out of the bloodstream and into the muscle.
What is the energy produced by mitochondria?
Here are the basics of energy production in the mitochondria: Your cells are already storing fuel, in the form of fats and carbohydrates that you’ve eaten. Once oxygen is introduced into a cell, it causes a chain of chemical reactions that lead the mitochondria to burn the fat/carbohydrate fuel stored in your muscles.
How does aerobic exercise work?
For humans the aerobic process begins with breathing. When you exercise, the body demands more oxygen than it would while resting. As a result, your breathing must increase to keep up with demand. At rest, adults typically inhale about 12 liters of air per minute. That number can jump to over 100 liters per minute when exercising. Our atmosphere is approximately 20% oxygen, so the oxygen that we need to function must be processed by our bodies first. When you take a breath, the lungs fill with air. That air is filtered through small tubes called bronchioles. The filtered air passes the bronchioles, eventually reaching thousands of microscopic sacs called alveoli. Inside the alveoli, Oxygen is diffused and begins to enter the bloodstream. The freshly-oxygenated blood travels to the heart, where some is used and the rest is sent along for reassignment.
How are mitochondria similar to cars?
Muscle s are similar to cars, in that they need fuel to run. The mitochondria is an organelle (a specialized structure within a cell), where the processes of respiration and energy production take place. The mitochondria is the ‘power plant’ that I referenced earlier, where oxygen is used in a chemical reaction to burn the body’s primary fuel sources, fats and carbohydrates. Think of mitochondria as tiny engines that use fats or carbohydrates as fuel, like a car uses gas. Here are the basics of energy production in the mitochondria:

Why is it important to train your heart?
This is good news for folks that haven’t been as active as they’d like, but want to get moving again. Aerobic training increases the diameter and mass of the heart, allowing it to pump faster and more efficiently. As a result, there is an increase in the amount of blood that the heart pumps with each beat. The amount of blood pumped per beat is called the ‘stroke volume’. A higher stroke volume means that the heart won’t need to pump as quickly to meet the demands of exercise. This is why well-trained athletes have lower resting heart rates than their non-trained peers.
How does aerobic respiration produce ATP?
Aerobic respiration can also use fatty acids from fat reserves in muscle and the body to produce ATP. In extreme cases (like starvation), proteins can also be broken down into amino acids and used to make ATP. Aerobic respiration would use carbohydrates first, then fats and finally proteins, if necessary. Aerobic respiration takes even more chemical reactions to produce ATP than either of the above systems. Aerobic respiration produces ATP at the slowest rate of the three systems, but it can continue to supply ATP for several hours or longer, so long as the fuel supply lasts.
How does the body respond to glucose?
By two minutes of exercise, the body responds to supply working muscles with oxygen. When oxygen is present, glucose can be completely broken down into carbon dioxide and water in a process called aerobic respiration. The glucose can come from three different places: 1 remaining glycogen supplies in the muscles 2 breakdown of the liver's glycogen into glucose, which gets to working muscle through the bloodstream 3 absorption of glucose from food in the intestine, which gets to working muscle through the bloodstream
How does glycogen get to muscles?
remaining glycogen supplies in the muscles. breakdown of the liver's glycogen into glucose, which gets to working muscle through the bloodstream. absorption of glucose from food in the intestine, which gets to working muscle through the bloodstream.

How often and for how long should I do these exercises?
The American Heart Association recommends that everyone reach a minimum of 30 minutes of some form of cardiovascular exercise 5 to 7 days per week. This can be broken up into 10-minute time periods. This means that taking 3 walks of 10 minutes each would let you reach the recommended minimum guideline for reducing the risk of heart disease, diabetes, hypertension, and high cholesterol. You would also burn the same number of calories as you would if you walked for the full 30 minutes at 1 time.

What is aerobic exercise?
Aerobic exercise provides cardiovascular conditioning. The term aerobic actually means "with oxygen," which means that breathing controls the amount of oxygen that can make it to the muscles to help them burn fuel and move.
How long should an aerobic workout last?
This allows the body to increase blood flow to the muscles and decreases the likelihood of a muscle or joint injury. The warm-up should last between 5 and 10 minutes. The cool-down session should last a similar amount of time as the warm-up, with the pace gradually decreasing. Stretching exercises would be appropriate after aerobic exercise.
How does heart rate affect exercise?
Your heart rate increases in direct correlation with the intensity of the exercise. Heart rate levels can vary significantly from one person to another based on fitness level, genetics, environment, and exercise tolerance. If you wish to train based on heart rate, contact your health care provider to determine what the appropriate range is for you. Some medications, most often blood pressure drugs, control heart rate, making it impossible to determine exercise intensity in this way. Ask your physician to determine if you are on any of these medications.
