A. Build muscle
When swimming, we move almost all the muscles in the body, from head, neck, upper limbs, chest, abdomen, back, hips, lower limbs, and feet. When moving in the water, the body expends energy is greater because they have to 'fight' the mass of water that can strengthen and flex the muscles of the body.
2. Enhance the ability of cardiac function and lung
Movement of water pushed and kicked by members of the body especially the hands and feet, can stimulate blood flow to the heart, blood vessels, and lungs. That is, the swim can be categorized as aerobic exercise in the water.
3. Increase height
Swimming is good and right will make the body grow taller (to which is still in the growth of course).
4. Trained respiratory
Highly recommended for people who get to swim because of asthma and respiratory system crdiovaskular can be strong. Respiratory us become healthier, smoother, and breathing may become longer.
5. Burn more calories
When swimming, the body will be felt more heavily engaged in the water. Automatic energy required becomes higher, so as to effectively burn about 24% of calories the body.
6. Self safety
With swimming we do not have to worry if one day experience things that are not desirable, especially relating to water (falling into the sea, etc.).
7. Relieve stress
Psychologically, swimming can also make your heart and mind more relaxed. Motion carried with a relaxing swim and slowly, to increase endorphins in the brain. Mood so cool, more cool mind, free agency was stifling.
Before the swim, so the body does not 'surprise', it is recommended to warm up movements to prevent muscle cramps at the same time also serve to increase body temperature and heart rate gradually and also cool down after swimming to body temperature and heart rate did not decrease drastically with how to swim slowly for 5 minutes.
For heating can be started by doing light movements, such as swinging arms and legs or walking around the pool for 10-15 minutes. Then gradually start with one lap to cross the pond, then rest for 30 seconds several times and peak swimming for 20-40 minutes without stopping. After several weeks, the exercise could be improved. Instead, changing the style of swimming so that all muscles trained.
The only 'shortage' of this sport is apparently less favorable for bone health. Absence of gravity forces them to swim just a bad influence on bone mass. To fix this, you can do other sports, like jogging, walking, or cycling.
