29 Jan Should You Leave An Empty Stomach Before Swimming?
Normally when people come to swimming, in addition to wanting a supple and healthy body, they need to go swimming to lose weight. This is also very understandable when swimming is considered a sport with miraculous effects in removing excess fat, toning the body.
And some women when it comes to swimming for the purpose of losing weight due to too much desire to lose quickly should enjoy fasting when swimming. So this is good or bad, will fasting while swimming will help women lose weight faster? Let’s go find out.
What is swimming?
Swimming is a water sport, due to the effect of body movement, especially the movement of the legs and arms, that swimmers can cross underwater distances at certain speeds. Thanks to the basic elements of water such as force from the bottom up (buoyancy), drag, lift …, swimmers can move on the water to move forward with many different swimming styles and styles.
Water is a liquid medium, so movement in water is moving in an environment that is foreign to humans. When swimming, the body is lying horizontally on the water surface. For that reason, swimming is different from any sport on land.
Swimming is basically an aerobic exercise because it takes a long time to train and the muscles require a constant amount of oxygen, except in the case of shortened water swimming when the muscles work in an anaerobic fashion. Like most aerobic exercise, swimming is thought to reduce the harmful effects of stress. Swimming can also improve body shape and develop a strong body, commonly known as “swimmer body”.
How does swimming work to lose weight?
Since it is considered an aerobic sport, when swimming athletes perform swimming movements, all muscles on the body must work continuously. At the same time, under the pressure of the water, the swimmer must also constantly use strength to bring his body forward.
It is because of the impact on the body under the pressure of such water that the swimmer’s body is usually very beautiful and standard. Areas such as the biceps, thighs, legs, and abdomen are all active to dissolve excess fat, making the body much cleaner.
How does swimming consume energy?
The first factor that affects the number of calories you burn while swimming is swimming intensity. According to the study, one minute of intense aerobic exercise burns calories equivalent to two minutes of slow or moderate-intensity aerobic exercise. If you swim faster and with higher intensity, you will burn more calories.
There are several other factors that are age and gender. Men tend to burn around 10 to 15% more calories than women when they exercise. And as you age, you burn fewer calories as well, and metabolism plays a major role in calorie expenditure as well. The more muscle mass a person has, the higher the metabolic rate, which means they will burn calories faster. Bodyweight can also affect the number of calories burned as the heavier the person, the more calories a person burns during exercise.
Swimming in cold water can burn more calories because the body will use more energy to keep us warm.
On average, a person weighing about 70kg will burn about 400 calories in 1 hour of swimming moderately and about 700 calories if swimming at high intensity for 1 hour.
Should we have an empty stomach before swimming?
Although swimming burns a lot of calories and fast, and it seems like starving swimming will help you lose weight. But the reality is not so.
When you do not eat anything, there are a number of consequences that you may experience:
– Not strong enough to swim for long and heavy periods. When you don’t get enough carbohydrates and protein, the muscle masses in your body don’t have the energy to metabolize and function.
– Easy to fall into hypoglycemia. When your body has hypoglycemia, you will feel tired, dizzy, and prone to fainting. These are all very dangerous things. You are also at risk of drowning.
– Hard to build muscle mass. Because the muscle masses in your body need the energy to function. So when you don’t put calories in, the muscle mass doesn’t have the energy to function.
– The risk of consuming a lot of calories into the body after swimming. The fact that you let your stomach go swimming will make you feel heavy, tired, and have no energy to function. And when you finish your swimming session, you will be in need of more food. This general invisible makes it easy to gain weight out of control.
Because of the above reasons, you should not allow an empty stomach to swim, especially with this heavy activity. Instead of leaving an empty stomach, you can opt for a healthy, fiber-rich snack.
