Upstairs said right, the main is usually more adaptive training. For example: in the professional boat simulator training, the use of simple training equipment (general naval base has a simple boat simulation rocker for officers and men to anti-seasickness training) and so on.
In addition, the Navy ships or bases are equipped with anti-seasickness drugs for emergency use. When the ship goes out to sea in bad weather, which causes severe vertical and horizontal swaying of the ship, in order to prevent seasickness, the officers and men on board the ship will also take some simple measures, such as reducing the movement, tie their bodies to fixed objects, etc.
On the other hand, the officers and men on board the ship will also take some simple measures to prevent seasickness.
Of course, in order to prevent seasickness, in addition to these, the most important thing is to strengthen the comprehensive physical exercise. But even so, the first few times you go out to sea, you will still encounter seasickness is normal. The first few times you go out on the water, you'll be able to get used to it.
2. In the sea seasickness is difficult to avoid
Seasickness is generally refers to the ship at anchor or sailing, due to the role of the wind and waves so that the ship irregularly bumps, rocking, vibration, so that the human inner ear vestibular equilibrium organs by abnormal ***, causing changes in pulse, blood pressure and respiratory rate, and even vertigo, pale skin, cold sweat and nausea and vomiting and a series of symptoms and physical symptoms of vegetative nervous reaction. The symptoms and signs of vegetative nervous reaction.
The incidence of seasickness is mainly affected by the marine environment, the type of ship, the nature of the work and the seafarer's own ability to prevent seasickness. Such as at the beginning of the voyage, more than moderate wind and wave conditions, the incidence of seasickness seafarers higher, up to more than 80%; larger tonnage, shock absorbing performance of the ship seasickness incidence of lower; the same ship on the cabin personnel than the cabin surface personnel seasickness incidence of high; on board the ship for a long period of time than on board the ship for a shorter period of time seasickness incidence rate is low.
In addition, the incidence of seasickness among seafarers is also affected by some other factors. Such as visual ***, when sailing to watch the external scenery, due to the line of sight constantly change easy to cause dizziness; seafarers in the body fatigue, mood depressed easy to happen when seasickness and so on.
So although seasickness is related to the quality of the seafarers themselves, but also affected by other factors, and not the longer the service at sea, the less likely to be seasick.
3. How the Marine Corps conducts anti-seasickness training
One of the reasons why the Marine Corps is a special force is that most of the time it has to cooperate with the surface ships or air force to accomplish the combat mission.
Marines on amphibious ships are the most basic and common form of force projection, and while Marines are good infantrymen, they must also be competent sailors who are able to adapt to shipboard life and remain mentally and physically fit after maneuvering over long distances on ships and arriving on enemy shores to fight. U.S. Fleet Marine Corps, is based on the operational needs of the mission, the Marine Corps, Marine Corps Aviation, amphibious combat ships mixed organization, Marines live in the amphibious ship for a long time.
Therefore, the Marines must have a good ability to adapt to ship life. The Navy's naval forces know a little bit of understanding of people know, sea sickness is the sea life must be endured test, in the eyes of outsiders, sea sickness is really difficult to people, but for the naval forces, these have been a commonplace, not worth discussing the subject.
In addition to a few regularly deployed task forces, most Marines are not normally deployed on ships. In their daily training, the basis for improving the Marines' adaptability at sea is targeted anti-seasickness training.
Through training, the Marines mastered the pathology of seasickness, maintain a normal mindset towards seasickness, and mastered some of the techniques to prevent seasickness, to ensure that the conveyance process is not reduced due to seasickness, which affects the ability to play in combat. It is a good idea to learn about the pathology of seasickness.
From the point of view of exercise physiology, seasickness is a kind of adaptive disease, mainly caused by the human nervous system to irregular movement, the internal environment of the ship (including smell, noise, bumps) and other maladaptive trigger, this adaptive can be improved through scientific training, and is reversible. The physiological mechanism of anti-sport disease adaptive training is that a series of physical and chemical *** are repeatedly applied to the sensory organs and nerve reflex centers which are closely related to sport disease, so that the corresponding sensory organs, nerve centers and mental processes will produce an adaptive phenomenon, and through the integration of the overall function and the regulation of the nerves and body fluids, the body will produce a kind of reversible and adaptive change of its physiological state, thus reducing the risk of the disease and reducing the risk of the disease. The body is able to produce a reversible, adaptive change in physiological state through the integration of the overall function and the regulation of nerve and body fluid, thus reducing the degree of reaction to a specific ***, improving the body's ability to withstand, and achieving the enhancement of the ability to resist sports disease, which is a physiological state of function and the adaptive change of the psychological feeling of the process.
Scientific studies have shown that 85% of people can improve their ability to resist seasickness through adaptive training, which in turn enhances their adaptability to shipboard life. Therefore, the anti-seasickness training of marines, first of all, to organize the learning of relevant pathological knowledge, in order to eliminate the fear of marines on the phenomenon of seasickness, and master the skills to overcome the phenomenon of seasickness, help to eliminate or minimize the negative impact of seasickness.
Physical fitness. The Marine's adaptation to seasickness is based on the principle of respecting physiological patterns and gradual progression.
In general, the physical fitness of the players, the adaptability of the ship will be stronger, and can quickly overcome the effects of seasickness.
In general, a good physical fitness for the ship will be better, and can quickly overcome the effects of sea sickness.
Targeted physical training includes strength, endurance, speed, sensitivity and flexibility training. The training centers around the following key aspects: strengthening muscle strength, especially waist and back, leg muscle strength training, to prevent the trunk and lower limbs muscle fatigue, soreness and weakness due to the long sailing time and limited space for limb movement, which affects the player's athletic ability.
Through long-distance cross-country running and pulling programs, aerobic endurance training is strengthened to meet the physical requirements of long-distance sailing at sea and carrying out high-intensity combat tasks after disembarkation. The training of endurance for special environment is strengthened to enhance the endurance for special environmental conditions such as lack of oxygen and poor air quality in the cabin.
The U.S. Marine Corps maritime adaptive training simulation chamber training. Simulated cabin training, that is, the construction of simulated sea ship rocking and cabin odors, noise and other environmental conditions, "anti-dizziness simulation cabin", the Marines close to the living environment of the special simulation of the ship training.
Simulated cabin training is the basis of the actual sea navigation training, the implementation of the process, according to the team's ability to withstand, and gradually increase the training intensity and length of time. You can also use simple training equipment, such as spinning ladders, wave wood, fixed rollers and other training equipment, to organize targeted training, improve the ability of the players to adapt to the unbalanced environment, to improve the adaptation to the purpose of ship life.
Or through the unarmed anti-seasickness combination drill, supplemented by anoxic interval running, etc., to reduce the sensitivity of the body's sensory organs to the rocking of the ship under the action of the sea (surging) waves, to improve the stability of the body's functions, and to enhance the human body's adaptability to the harsh environment of the ship's cabin and its ability to withstand. Overcome the harsh environment of ship life, enhance adaptability, psychological quality is very important.
Marine anti-seasickness training must be synchronized with targeted psychological training. It mainly includes psychological tolerance training and attention transfer training.
Through training, eliminate the fear of seasickness, enhance the ability to adjust the mind, so that the marines from the psychological "desensitization" to seasickness, to improve the ability to resist seasickness purpose. The actual sailing training with the ship.
Marines and ship forces to bundle training, is to improve the amphibious warfare ability of the effective form of training. Marines anti-seasickness training, the most important part of the training is to go to sea with the ship, the actual work and life on the ship.
In the training, the choice to take the current service of the main battle amphibious transport ships, the actual sea navigation training. Organization and implementation, adhere to the principle of gradual and orderly progress, first choose the small wind and wave sea conditions for adaptive navigation, training time can also be relatively short Marine Corps and landing ship training, so that the players feel the actual ship life.
Then gradually lengthen the training time, intentionally choose the larger wind and waves for continuous long-distance sailing training.
These are the first time I've ever seen a ship in the air, and I've never seen a ship in the sea.
Strengthen the handling of special circumstances, the players appeared serious seasickness vomiting phenomenon, to take some necessary medical measures, and supplemented by psychological guidance, to help the players to establish confidence to overcome seasickness, so that the gradual improvement.
4. What are the main naval sea clothing
The clothing worn by the sailors on the surface of the ship when they go out to sea for combat and training.
Usually, the top shirt is a small lapel, and the bottom shirt is a pair of pants. It is windproof, waterproof, warm and lightweight.
Winter sea clothing for the upper and lower garment decomposition, waterproof cover and warm layer separate, under the sea cap has a large shawl and the top knot. The waterproof cover is made of neoprene scraped tape, and the warmth layer is a mixture of fine wool and acrylic flakes.
The fabric is waterproof rubberized cloth, with a warm layer of cold protection. The warm layer is generally made of synthetic wool, or made of acrylic fiber and wool processing.
Yacht sea clothing for missile, torpedo speedboat cabin surface personnel to wear when sailing, with windproof, waterproof, warmth and other properties. Sea service training clothes are the standard work clothes used by the ship personnel on duty at sea.
When the ship sails, fights, and anchors at sea, in order to ensure that the personnel can live and work normally under the harsh conditions of the sea environment, different kinds of ships are equipped with work clothes with corresponding protective performance. Chinese people's *** Navy to the late 1970s, the initial formation of sea service special workwear series, mainly speedboat sea clothing, speedboat boots, submarine linen undershirts and pants, submarine work shoes, surface ships, submarine cold suit, submarine cold suit, nuclear submarine coveralls, speedboat carpet socks and so on.
5. Crew how to prevent seasickness knowledge
As a usually chatty me, usually see the company waiting for business seafarers, will often pull them nagging, after all, the life of the sea for me is strange and magical.
Different seafarers have different descriptions and memories of the sea. Some seafarers will talk excitedly about having crossed a certain strait to enjoy the beautiful scenery of a foreign country and lament the wonders of nature; others will proudly talk about having survived the stormy winds; and even seafarers who have never sailed before have completely different imaginations of the sea.
But most seafarers who have been to sea are plagued by one problem: seasickness! Even experienced veteran seafarers will occasionally experience seasickness. So why do seafarers get seasick, and how can they not get seasick? Today, I will teach you! The sea is unpredictable, the last second is calm sea, the next second may be rough.
The ship by the wind and waves will be irregularly bumpy and rocking, when some seafarers will appear dizziness, pale skin, cold sweat, nausea and vomiting and a series of symptoms, which is seasickness. Want to solve the problem of seasickness, then we first need to understand why seasickness.
Seasickness Seasickness is caused by the brain receiving incorrect information in the environment, the sensory organs are constantly collecting information from the outside world and transmitting it to the inner ear. The vestibular apparatus of the inner ear is the body's balanced sensory organ that organizes the transmission of this information to the brain.
Seasickness occurs when the ship's rocking *** reaches the vestibular apparatus of the inner ear, and the balance system realizes that the information it receives is different from that received by the eyes. The vestibular apparatus of the inner ear produces excessive bioelectricity, which affects the central nervous and vegetative nervous systems, followed by symptoms such as cold sweats, nausea, vomiting, dizziness, irritability, and sleep disturbances.
Here to the seafarers who have not yet been on the ship to take a precaution Oh, according to a study in 2001, the Second Military Medical University, the 100 first sea voyage of the University of line for observation, in 13d, 4 wind and wave changes occurred, 4 times all the seasickness disease accounted for 39% of the people, 92% of the seasickness of the people for the moderate seasickness. Mild Dizziness, drowsiness, pharyngeal discomfort, increased salivation, pallor, cold sweat Moderate Anorexia, nausea, vomiting, pallor, headache, dizziness Severe Worsening of the above symptoms, more than vomiting, dehydration, debilitating weakness, cold extremities No reaction No any of the above symptoms As long as the phenomenon of seasickness occurs, it affects the life and work at sea, and prolonged seasickness may even make people resistant to working at sea. The first thing you need to do is to get rid of the symptoms of seasickness, which will affect your health.
This is not a sensationalist Oh, the following facts tell us that seasickness is not a small matter, seafarers must pay attention to friends, this is related to our own physical and mental health. *** The 421st Hospital conducted a survey of the medical and health personnel on board of a Ministry of Hospital, and found that after sailing for a period of time, there will be 54% of the people appearing seasickness symptoms, followed by difficulty in concentrating, easy to agitation, easy to cry, loss of appetite, vomiting, sleep disorders, and other symptoms.
*** 442 Hospital on 638 Navy and 432 land soldiers of the gastroscopy results of comparative analysis, the Navy group peptic ulcer, chronic gastritis and duodenal bulbous inflammation of the three categories of disease, the incidence rate is 60.89%, while the land soldiers for 23.11%. Among the seafarers suffering from chronic upper gastrointestinal diseases, 32.1% were accompanied by bile reflux, compared with 12.65% of land soldiers.
The high prevalence of peptic ulcers and bile reflux are two characteristics of seafarers. The authors of their article believe that it is mainly related to the reaction to seasickness, which disturbs the central nervous and vegetative nervous systems and is a disturbance of gastrointestinal function and intestinal hormone secretion.
At the same time, vomiting due to seasickness can cause digestive esophagitis, hypovolemia, hypokalemia, hypokalemia, hyponatremia, alkalosis and other problems. The Second Military Medical University conducted a study on the effect on amino acid metabolism during seasickness through rats, which showed a significant increase in amino acid content in the liver and a significant decrease in amino acid content in the brain.
Amino acids are the basic components of proteins, proteins but the body's three major energy-supplying substances, when their metabolism produces changes in human health is also very unfavorable. Finally explained seasickness, but only explain not solve the problem of seasickness I am not good me.
The following text highlights the blackboard, must pay attention to the knowledge. Seasickness essential knowledge 1 Seasickness gymnastics Nanjing Medical University in 2006, an experimental study of 128 students to prevent seasickness training and evaluation of the effect of the disease.
It was found that after 20d-40d of comprehensive training, it played a better role in preventing seasickness, and the longer the training time, the more often, the better the effect. Since the report does not give specific anti-seasickness drill, I still search for a set of anti-seasickness gymnastics for you on the Internet, we quickly collect.
The first section: the beginning of the preparatory state, legs open, two hands on the waist, eyes closed. Head quickly to the right, to the left.
Move at 2 times per second for 30 seconds. Section 2: Squat down and support your body with your left leg, right leg outward.
Rotate your body 90-180 degrees at regular intervals, 3-4 times, then change to the other direction. Section 3: Legs apart, hands on the waist, eyes closed.
Nod your head back and forth quickly, 30 seconds per section, 2 times per second. Section 4: Legs apart, hands spread, lean back and land as hard as you can with your hands.
Then lean forward and put your hands between your feet. Repeat the whole movement 4-6 times.
Section 5: Hands on the waist, eyes closed. Tilt your head to the left and right, 30 seconds per section, 2 times per second.
Section 6: Split your legs, spread your hands flat, body to the left, left hand behind your back, right hand up. Then change direction and repeat 4-6 times.
Section 7: Stand upright, jump upward in place, while rotating the body 180-360 degrees, or even more drastically, and then jump upward. This continuous jump 2 times to change the direction of rotation, repeat 6-8 times.
2 drug prevention People around often say, seasickness in advance to eat on the seasickness medicine on the good, I think when there is no heavy seasickness or try not to use seasickness medicine. When there is frequent vomiting, you can use anti-5 hydroxytryptamine drugs, belonging to the strong antiemetic drugs.
Specific use, seafarers friends or to consult the doctor do not use their own arbitrary Oh. 3 strong tea Many people have heard, in the car before the boat drink a small cup of strong tea (strong tea refers to each cup with more than 3-4g of tea brewed tea), you can prevent or alleviate seasickness and motion sickness.
Although this practice I have not found the exact scientific basis, but many people.
