The diving is an underwater activity that can be performed for recreational sporting purposes or research. It consists of entering the water and submerging the entire body, which is why, in general, it is developed with the help of some type of equipment that allows the diver not to have to come to the surface to breathe.
For example: “I would like to take a diving course before traveling to Mexico”, “Many tourists choose to dive in the lake, although others prefer to go hiking on the hill”, “The diving instructor suggested that we stay close to too much of the boat ”.
When the person decides to dive without any type of apparatus or equipment, we speak of free diving. This practice simply involves diving into the water and swimming below the surface while holding your breath. For logical reasons, when diving in this way, we must go afloat very often to take oxygen. Therefore, it is impossible to reach great depths.
To observe underwater wonders, such as corals or fish, it is more appropriate to have a diving equipment. Certain basic components are protective masks for the eyes (which facilitate vision under water), fins or frog legs (to facilitate movement), a protective suit (which allows us to resist low water temperatures, especially in the deeper areas) and, of course, the oxygen tank with the rest of the associated elements to be able to breathe underwater.
It is possible to dive close to the surface without the aid of additional oxygen. We only need a snorkel, which is an elongated tube that goes from the individual’s mouth to the surface and that allows breathing even when the subject is with his or her face under water. The less demanding alternatives to diving are the most sought after by tourists and people who are curious but do not have the necessary training or want to acquire it.
Since many people have been able to swim from a young age, the importance and level of demands of physical and mental preparation that any individual wishing to dive must undergo is often overlooked; As a curiosity, something similar happens with the training to become an astronaut, saving the distances.
For human beings, water is a very unstable and, at times, unpredictable environment, which forces us to make a greater physical effort to move than we are used to on land. It goes without saying that we are unable to breathe once submerged, which is why training should make us able to make the most of our energies to face all limitations and know how to overcome emergency situations.
Adequate aerobic work collaborates with the adaptation of the respiratory and cardiovascular systems to the diving experience, helping us to improve aerobic glycolysis (obtaining energy) and to save our resources, to be as efficient as possible when performing movements under Water.
One of the key exercises of the training aims to extend the time of apnea, that is, the time 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 the intensity and frequency of the practices, and to 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.
