He diving is a underwater activity It can be done for recreational, research or sports purposes. It consists of entering the water and submerging the entire body , so, in general, it is developed with the help of some type of equipment that allows the diver not to have to go to the surface to breathe.
For example: “I would like to take a diving course before traveling to Mexico”, “Many tourists opt for diving on the lake, although others prefer to hike on the hill”, “The dive instructor suggested that we don't get too far from the boat”.
When the person decides to dive without any device or equipment , talk about Free diving . This practice simply involves immersing yourself in the Water and swim below the surface while holding your breath. For logical reasons, when diving in this way, we must float very frequently to take oxygen. Therefore, it is impossible to reach great depths.
To observe underwater wonders, such as corals or fishes , it is more appropriate to have a diving equipment . Certain basic components are protective eye masks (which facilitate underwater vision), frog's fins or legs (to facilitate movement), a protective suit (which allows us to resist low water temperatures, especially in the deepest areas) and, of course, the tank of oxygen with the rest of the associated elements to be able to breathe underwater.
It is possible to dive near the surface without the help of additional oxygen. We just need a snorkel , which is an elongated tube that goes from the mouth of the individual to the surface and allows breathing even when the subject is with the face under water. The less demanding alternatives of diving are the most sought after by tourists and people who are curious but do not have the training necessary or want to acquire it.
Since many people know how to swim since childhood, the importance and level of demand of the preparation physical and mental to which any individual who wishes to dive must submit; As a curiosity, something similar happens with training to become an astronaut, saving distances.
For humans, water is a very unstable and sometimes unpredictable medium, which forces us to make a greater physical effort to move from what we are used to land. Needless to underline our inability to breathe once submerged, so training should make us able to make the most of our energies to face all limitations and know how to overcome emergency situations.
Proper aerobic work collaborates with the adaptation of systems respiratory and cardiovascular to the diving experience, helping us to improve the aerobic glycolysis (to obtain energy) and to save our resources, to be as efficient as possible when making underwater movements.
One of the exercises The key to training is to extend the time of apnea, that is, what we are able to resist without breathing. It is always advisable to have the supervision of a tutor, to indicate the proper progression of the dives and to assist us in case of dizziness.
Some of the recommended activities to improve lung capacity are swimming, dancing, steps, aerobics and cycling. The most important thing is to be constant in intensity and frequency of practices, and increase the variables progressively, as the body adapts to the demands. It should be clarified that all this depends on the age and conditions of each person, so you should not proceed without adequate knowledge.
