Be extremely wary of swimming cramps (Part 1)

Swimming cramps are a very dangerous phenomenon. This phenomenon reduces swimming ability, more serious can cause swimmers drowning.

Cramping can happen to everyone, including those who are good at swimming. The following article will help us better understand the phenomenon of swimming cramps.

1. What is cramps?

A sudden muscle spasm is called a cramp. This is an unwanted phenomenon and causes severe pain in the muscles, making it more difficult to move.

Cramps are usually found in the knees and ankles, and can also occur in the thighs, hips, hands, feet, abdominal muscles.

The cramping phenomenon can occur at any age, but the most common subjects for this phenomenon are those who regularly play sports and the elderly.

2. Why swim easy to get cramps?

Some of the main causes of swimming cramps include:

Do not warm up before swimming;

Use excessive force while swimming;

Because the body is not getting enough calcium.

When swimming in water, especially when the temperature drops, cold water causes our body to lose heat quickly. In order to generate internal heat and maintain the main temperature, the body begins to tremble. The thermoregulation mechanism is activated by the hypothalamus, causing the vessels that supply blood to the extremities to begin to contract to prevent heat loss from the major organs. This leads to a lack of oxygen on the limbs, and in low temperature conditions, cold water, it is very easy to swim cramps.

When exercising, if you try too hard, sweating too much (dehydration) also makes you more prone to cramps.

When swimming, the toes stretch causes all the organs of the foot to form a tight line from the calf to the toes. Keeping your feet like this when swimming is also the reason why you are prone to swimming cramps.

Swimming cramps are dangerous because the pain from cramping can reduce your ability to swim, more seriously, drowning.

From Michael Phelps to business lesson (Part 2)

2. Conquer your own mentality

One of the best therapies used by Phelps before a game is sense of breath. This is said to stimulate blood circulation in the body, helping energy circulate better. Another thing Phelps likes to do is listen to music until the very last moment before entering the competition. In 2005, Phelps told The Guardian that “it relaxes me, and takes me into my own little world”.

When Bowman first coached Phelps, he noticed that Phelps had problems coping with stress and his ability to calm down before race. Later, Bowman bought a book about relaxation exercises that read something like this: “Clench your hands into fists and relax. Imagine the tension slowly melting. ” Then he asked Phelps’s mother to read this again to Phelps every night so he could relax his body before going to bed.

Achieving a state of calm can be a bit difficult for many business owners, and it’s really hard to do with a chaotic mind and a tense body. Take the time to find effective relaxation techniques, especially when stressful situations are hidden ahead. A comfortable mind will give us wise choices in business as well as in life.

3. Cultivate good habits

Bowman believes the secret behind Phelps’ victories is the creation of good habits, which helps Phelps become the strongest mentally challenged swimmer. When Phelps was a teenager, Bowman asked Phelps to imagine a perfect race and how he would win it.

Once some core habits are established, all other habits such as maintaining the right diet, exercising muscle tension, and sleeping time properly will automatically appear. According to an article in the Baltimore Sun , Phelps rarely stayed up late after 10 p.m. He also wears devices to determine the depth of sleep and a detailed tracking sheet for each food he consumes each day.

Great business owners will achieve their goals if they pay attention to the habits they build on a daily basis. Good habits will help them solve problems, build good relationships with others, and come up with new ideas that can make their business viable with challenges and time.

From Michael Phelps to business lesson

The rules that make Michael Phelps the most Olympic medalist in history will also help you win the marketplace.

Becoming a business owner is like becoming a professional athlete. You must have strict discipline in managing your own time and resources. You have to be really calm to face the pressure of giving presentations to investors or advising difficult clients. And most importantly, you must be highly focused on achieving the goals you have set for yourself and your company.

So, what athletes can do all of the above?

That is Michael Phelps.

At the end of the 2016 Olympics held in Rio de Janeiro, Phelps brought 5 gold and 1 silver medal to the United States. This achievement also brought the total number of medals he won to 28 (including 23 gold), something no one else in history has done. Phelps also announced that this is his last Olympics. However, I do not know if this is true because, after the end of the 2012 Olympics in London, he said the same thing.

Regardless of whether Phelps will retire in the next Olympics, here are three pocket things you can learn from him.

1. Let challenges lead you to success

An article on the site said Phelps was diagnosed with attention deficit disorder (ADD) as a child. Therefore, swimming has been recommended by the doctor to the Phelps family as a remedy for this. No one expected that when the boy Phelps started swimming at the age of 7, one day he would break a series of records to become the most successful Olympic athlete of all time.

In 2014, Phelps was arrested for driving while drunk, which forced him to find a way to quit drinking and take a strict self-examination. An article by the Baltimore Sunsaid that after going through that incident, he “raised his love of work to a new level”. And when village coach Bob Bowman visits Phelps in a re-education center in Arizona, he finds that he “seems determined to have to deal with the darkest patches of his past”.

As a business owner, sooner or later you will find yourself falling into unintended adversity. Successful people move forward in the midst of challenges, and turn transient failures into spark that ignites the desire to win ultimately.


Things to know about first aid for drowning (Part 2)

2. Things to avoid when drowning

Most victims of asphyxiation when taken to the emergency department of hospitals do not receive first aid or improper first aid resulting in death or brain sequelae due to lack of oxygen. Incorrect first aid methods include:

– Spending a lot of time on the water shock: the upside down movement is unnecessary and should not be done because often the amount of water entering the lungs is very little, not the lungs filled with water like people think. This very small amount of water is expelled when the victim breathes again. In addition, flushing also slows down the emergency time and increases the risk of choking.

– Roller roll: for children to lie on their stomach on a pot to let the burning straw inside roll back and forth in order to “drain the water” in the child’s body. This method is ineffective, and also causes burns to the child.

– The victims of cardiac arrest apnea are not given first aid to suffocate and press the heart at the place where the accident occurred or while transporting the victim to the medical facility. This causes the brain and organs to be chronically deprived of oxygen, brain cell death leads to death and severe brain sequelae. So, it is best to have ambulance as soon as possible to get the victim’s head out of the water before bringing it ashore.

3. The following factors increase the risk of asphyxiation

  • Can’t swim or appreciate his swimming ability.
  • Risky behaviors such as bathing in the river, playing on the banks of lakes, …
  • Lack of adult supervision.
  • Hypothermia leads to rapid exhaustion and inability to swim.
  • No primary arrhythmia was detected.
  • In older children it can be caused by drinking alcohol, drug use …
  • Injury, cerebral vascular accident , myocardial infarction .
  • Increasing ventilation before jumping into water reduces PaCO2, while PaO2 decreases to 30-40 mmHg due to consumption. Because the PaCO2 is reduced, it does not stimulate respiration. This causes cerebral hypoxia, convulsions, loss of consciousness leading to drowning.

Things to know about first aid for drowning (Part 1)

Drowning is a form of asphyxiation, caused by water being inhaled into the lungs, or blocked airways from spasm of the larynx while the victim is in water. This is a common accident that occurs while swimming, boating and during water activities. However, it can also happen at home such as in a water tank, a jar, a drain, etc.

When suffocated, the victim stops breathing, the heart beats slowly due to reflexes. Apnea continues to lead to hypoxia, increasing heart rate, and blood pressure. If breathing stops persist for about 20 seconds to 2 – 5 minutes (depending on the victim), the threshold is reached and the breathing reappears, causing water to be inhaled causing immediate laryngospasm. second breath apnea followed by forced breathing breaths causing water and foreign objects to be inhaled. As a result, the heart rate slows down, arrhythmia, cardiac arrest and death.

1. How to first aid drowning

First aid in place and the right technique is the most important, determining the survival or sequelae of the victim’s brain.
In order to save the life of a suffocated victim, the above processes must be promptly stopped, preferably right from the first stop of breathing, i.e. within the first 1- 4 minutes of being submerged in water, and handling well. comorbid injuries (especially head, neck and spine injuries ).

The correct first aid method is as follows:

  • Quickly remove the victim from the water surface by holding the victim’s arm, long pole to grasp, tossing the victim or picking up the victim.
  • Place casualty in a dry, well-ventilated place
  • If the victim is unconscious, check if the victim is still breathing by observing the movement of the chest:
    + If the chest is not moving, the victim is not breathing, perform the cardiac out of the chest half. under the sternum. Combine cardiac pressure and asphyxiation at the rate of 15/2 (2 ambulance) or 30/2 (1 ambulance) for 2 minutes and then reassess if the victim is breathing again? Are lips pink? Is there a reaction when shaking stimulates pain? If not and must continue these emergency operations even on the way to transfer the victim to a medical facility.
    If the victim is still breathing on his or her own, place the victim in a safe position lying on his side so that the vomit can easily escape if the victim is vomiting.
  • Remove wet clothing and keep warm by covering the victim with a blanket or dry towel
  • Promptly bring victim to a medical facility even if the victim appears to be normal or recover completely from first aid as the risk of secondary dyspnea can occur several hours after suffocation

Science has shown why we should go into the water and swim for its exceptional benefits.

1. Swimming is good for the lungs

When your face is underwater, oxygen is at a high level. Your body will adapt to use oxygen more efficiently. Plus, it will learn to breathe in cleaner air with each breath and release more C02 with each exhale.

A study in the Indian Journal of Physiology and Pharmacology also found that swimmers have better heart rates than runners. This means they have lower blood pressure and will function better.

2. You will run better

By increasing your ability to absorb and use oxygen efficiently, swimming increases your stamina.

According to the 2013 Journal of Sports Medicine and Science, controlled swimmers improved running performance by 6% after just 12 swimming sessions.

Your stress level will decrease when you go into the water to exercise. According to research published in Pain Research & Management, being submerged in water really feels calm and relaxed.

4. You could be smarter

According to a study in the Journal of Physiology, blood flow to the brain increases up to 14% when the body is submerged in water. Researchers believe that the pressure of water on the chest cavity may be related to it, and they are currently investigating whether water exercises improve blood flow to the brain better than the upper exercise. ground or not.

5. Swimming offers a great experience

Swimming is a life skill and it opens many interesting doors. Mastering swimming will help you have a great experience when it comes to participating in better water activities more easily.
