What happens to our bodies when we exercise?
Muscles contract to create movement and use up more energy than normal to do so. The body is burning calories of macronutrient from fat or carbohydrate.

It is possible to exercise to the point of heat exhaustion. At that point you would collapse and stop. You'd probably stop at about 39 C. The accumulation of heat during exerc…ise is serious problem that the body needs to solve. An increase in the rate of respiration, and diverting as much blood flow the skin are the two main mechanisms for the dispersal of heat from the body.
Lack of exercise can contribute to cancer, diabetes, heart disease, stroke, cognitive decline and dementia, loss of muscle mass, osteoporosis, depression, obesity, and immune …function.
What could happen to you and your body if you don't perform a proper cool down routine after exercising?
You may have sore, stiff muscles. Blood may not return to your heart, which may leave you feeling dizzy, sick to your stomach, or worn out. ---------------------------_@@@@@@@…_ --------------------------@___________@ -----------------------@_@________@__@ ---------------------@___@______@____@ -------------------@_____@____@______@ -------------------@______@__@_______@ -------------------@_______@@________@ -------------------@________@________@ --------------------@_______@________@ ---------------------@______@________@ ----------------------@_____@_______@ -----------------------_@@@@@@@@@_ -----------------------------APEX =)
It makes you breathe faster and your heart beat faster. Because of this, you get hotter, and sweat more. This means you consume more water, or get dehydrated. Your muscles… will develop micro tears in them. As they heal, they grow, and get bigger and more powerful.
Heart rate and stroke volume will both increase when you exercise because the heart will have to beat faster in order to transport more blood around the body, and every be…at will pump a larger volume of blood out of the heart. This means that oxygen and essential nutrients can be transported around the body more quickly and efficiently to where they are needed. Blood pressure is the pressure of the blood in the arteries as it travels around the body and due to this, it will also increase as a result of increasing heart rate and stroke volume. Respiratory rate and tidal volume will both increase because you breathe more often and heavier when exercising. As a result of this, respiratory minute volume (RR*TV) will increase because the amount of gas inhaled or exhaled from the lungs in a minute will get larger. All of these changes will begin to happen as soon as you start exercising and will continue to increase until you finish exercising.
Regular aerobic activity - such as walking, bicycling or swimming - can help you live longer and healthier. The benefits of aerobic exercise are powerful, and aerobic exercise… needs to be a part of your fitness program. Aerobic means "with oxygen," so when you exercise aerobically your body uses oxygen to help produce energy during the exercise. Your heart and lungs have to work harder to continuously deliver oxygen to your body during aerobic exercise, and this strengthens your heart and lungs. There are plenty of ways that you can exercise aerobically. You can walk, run or bike. You can use a treadmill, stationary bike, stair stepper, elliptical machine or rowing machine. You can take an aerobic exercise class. Here are the top five benefits of aerobic exercise: 1. Helps prevent health problems 2. Strengthens the heart 3. Helps keep arteries clear 4. Strengthens the respiratory system 5. Reduces body fat
Breathing rate increases to ensure more air inside the lungs and so more oxygen Heart rate increases to ensure more blood is available to all working muscles and other tissue…s; this helps in getting more oxygen and more nutrients for energy. Muscles who actually responsible to create activity in the body contracting and relaxing and they cause movement in the joints; in this process energy is spent. Brain needs lot of sugar (glucose) every second to function efficiently and this is maintained by blood sugar at 80-120 mg/DL always and this is the responsibility of liver.Your heart pumps blood through your body at a much quicker pace, which makes you burn more calories/energy. There are a lot of things that happen when we exercise... if you are doing a cardio exercise, the brain tells the body to perform a specific muscle contraction (lets say jogging) the body releases calcium in the leg muscles to perform a contraction, this contraction is just a single action of a repetitious action that will take place when we perform jogging. The body also needs oxygen to make this contraction so the brain tells the body to take deeper or more air to support the muscle contraction needed to perform the cardio exercise . The increase of air intake will also mean an increase of "pumping" for the heart because it is our blood that brings the air (oxygen) to the muscle that contracts. Now we also have to consider the glycogen (carbs) that was stored by the body, it is use by the body as fuel or energy. Normally the body with use the glycogen for the first twenty minutes then it changes to fat for fuel specially if you are between 60% - 70% of your theoretical maximum heart rate. All these happen from the time you start your first step for jogging...
The body does not like to waste energy, it does not like to keep unnecessary things around. If a muscle is not used, there is no stimulation to build it, and the cellular tur…nover will eventually cause it to atrophy. As muscle atrophies, you become weaker and can not exert as much force. You will not burn as much energy with exercise this way due to less strength and endurance. Your resting metabolism will also lower. Essentially, if you are eating the same amount, if you reduce your exercise, the calories normally spent during exercise, repairing muscles and building them will instead be stored as adipose (body fat). Someone who reduces exercise should also reduce calorie intake if it is to excess, to prevent unneeded fat from accumulating. Exercise also has many health benefits. Endorphins are released that make people feel well. The joints are made supple and range of motion can be attained. People can feel stiff and sad without movement. This may also negatively affect the immune system. Exercise can increase cardiovascular health and allow you to breathe better. Without the oxygen, there is less energy to operate the immune system. Your lymphatic system would also not be stimulated without motion and you will have a more difficult time detoxifying your body of contaminants and invaders.
you wouldn't be losing any fat.
Exercising can make you fit. it also makes you more flexible =P, and it is good for you but it also builds up your body and helps your immune system exercising is hard to mant…ain but make sure you give yourself a break for water and after running or whatever eat a banana or something :)
There are minerals which our bodies need (especially during strenous exercise) called electrolytes - Sodium, Potassium and magnesium especially. These regulate functioning o…f muscles (think lubricant) and are run down during strenous activity of long periods of time while exercising. Its these electrolytes which keep your body performing at optimal temperatures and rates of efficiency, when this lubricant is depleted your muscles cant function smoothly and get stuck and knotted with the impending 'why now' reaction a cramp gives you! Its important to keep up good mineral nutrition prior to and in recovery from heavy sessions, to allow your body to perform at its peak condition, and during long periods (especially in warmer weather/regions) to drink sports drinks which include these minerals for this reason. Muscles can also cramp, by going from one extreme to another. A classic example of this which not too many people will be familiar with is when cycling and descending a long steep mountain pass where you do not pedal hard much/at all for up to 30 minutes! when you get to the bottom of the mountain and ride up the next one 'cold' too hard at first you have a good chance of bringing on a cramp if your legs are also tired and full of lactic acid. Lactic Acid: The burn you feel during exercising is mostly due to the buildup of lactic acid in the blood. Lactic acid is a byproduct of strenous exercise, which begins to accumulate at a certain effort and then builds up faster than it can be flushed away at strenous levels. During aerobic exercise this slow buildup of lactic acid over hours (or less with very high levels of effort) causes your muscles to fatigue and this is felt with a burning sensation in muscles used.
It affects you physically. It can also affect you psychologically (emotional & mentally.) Doing at least 30minutes of what ever type of exercise, a day as long as its exercis…e, even just a walk in the park can clear your head and get you thinking about things and can take a lot of the everyday pressures and stress from the environment we live in. By exercising it can also release happy/feel good chemicals called "endorphins" that can make you feel more positive about your out look in life and also how you perceive your body image. Exercise can also keep you fit and healthy and help the blood flow around your body as well as, tone up, lose weight and overall feel and look good. By not exercising, you will not feel any of the above, you will have more mood swings, less energy, weight gain and feel more sluggish!You lose muscle tone and general physical good health.
In response to exercise there is added muscular stress. More energy is consumed, and oxygen is depleted by an increase in aerobic metabolism. To replenish this oxygen, the hea…rt pumps faster. Depleted blood is brought to the lungs faster to be refilled, and this oxygen-enriched blood is pumped faster to the starving cells. More frequent breaths Deep breaths Redness Sweating Dehydration Muscle strain SWEATTTTTTTTTTTTTTT! SWEATTTTTTTTTTTTTTT! SWEATTTTTTTTTTTTTTT!
You breath in oxygen and it circulates your body in the blood. Each cell gets individual help. Oxygen goes into the cell and carbon dioxide comes out. blood goes around your b…ody until it is deoxygenated. it enters your heart through the right side, goes to your lungs where the alvioli produces the oxygen. it the enters your heart though the left side then circulates your body. When you exercise the body uses the energy stored in fat to maintain homeostasis.
Answer If you are eating junkish and are not exersizing, you will become overweight, and eventually, if you keep it up, obese. You will have heart problems, and you…r organs and your entire body will be much worse than they would be if you treated them right. You will also have low self-esteem and will constantly be unhappy with the way your body looks. Unless you have a speedy metabolism, you will gain weight.
Exercise uses energy, but can build the strength and endurance of muscles. Many people use execise to reduce their body fat, but not all of the calories burned are fat: muscle…s use glucose and protein for energy as well. "Aerobic" development allows the body to better use oxygen in the metabolic process, providing more energy and for a longer period.
