Why do some people swim so fast?

Some people swim quickly, and the reasons may include the following:

1.Technique: A fast swim requires proper technique and posture. Professional instructors can provide guidance and training to help swimmers increase speed and efficiency.

2.Body Structure: Some people have a body structure that is suitable for swimming. For example, they may have longer arms and legs, which can help them paddle farther and faster.

3.Strength and endurance: Swimming requires strength and stamina. Regular exercise and training can help swimmers improve their abilities in these areas and thus swim faster.

4.Psychological factors: Psychological factors can also affect swimming speed. For example, self-confidence and determination can help swimmers overcome difficulties and challenges to swim faster.

Overall, swimming speed depends on a variety of factors, including technique, body structure, strength and endurance, and mental factors. With training and practice, everyone can improve their swimming speed.

Swimming is a highly technical sport that requires special practice or training to master the technique.

The person you said about swimming faster must have practiced hard and mastered the movement skills of swimming, so they swim faster.

I've been swimming for more than 10 years, and I've learned the essentials of water and breaststroke, and I've improved a lot compared to when I started, I can swim more than 1,000 meters at a time, and I can reach 5 minutes in 200 meters, but there is still a lot to improve.

For beginners, the most important thing is to be regular, followed by relaxation in the water, and finally to be able to breathe freely. Survive these three levels and you'll be at least faster than many people.

Ask again.

You choose a good coach and you're going to make a qualitative leap right away.

Indicate a talent for swimming.

The breaststroke is the slowest of the four strokes because the breaststroke involves extending the arms and tucking the legs underwater. Extending arms and tucking legs not only does not produce propulsion, but also drag.

Whereas, breaststroke has a shorter stroke arm distance, a short distance to act on the water, and less propulsion is generated. If you want to improve the breaststroke speed, you should start from three aspects: 1. Reduce the forward resistance. Second, improve the efficiency of propulsion. 3. Master the timing of arm and leg coordination.

Freestyle. 1. In the freestyle competition, any swimming style can be used. However, in individual medley and medley relay competitions, freestyle refers to swimming styles other than butterfly, backstroke and breaststroke.

2. Every time you turn and reach the finish line, a certain part of the athlete's body must touch the pool wall.

3. During the entire swim, a certain part of the athlete's body must be exposed to the water. After the start and each turn, the athlete is allowed to be completely dewatered, and the athlete's head must be exposed to the water before 15 meters (inclusive).

Backstroke. 1. Before the start signal is issued, the athlete should face the starting end in the water and grasp the starting handshake with both hands. Do not put your feet in the sink, on the sink, or hook your toes on the edge of the sink.

2. After starting and each turn, the athlete should kick off the pool wall, except for the turning action, the athlete should always be in a supine position during the whole swimming process, and the body is allowed to rotate, but must maintain a supine posture with the horizontal plane less than 90°, and the head position is not subject to this limit.

Bodybuilding, life lies in sports. Strengthens lung function.

Because that's their hobby.

Because the density of human beings is about the same as the density of water, they can float like ice can float.

In fact, the way to learn to swim is to let people learn how not to sink, people are actually born with water, because the baby is in the mother's womb is in the amniotic fluid.

When it comes to how to float, we have to talk about why it floats:

According to Archimedes' principle, we know that the buoyancy of an object is equal to the gravitational force expelled by the object into the water, and the more volume you enter the water, the more volume you expel from the water, the greater the gravity of the water, and the greater the buoyancy you are subjected to, the easier it is to float.

Another way, you can take a deep breath, so that the chest cavity expands in volume because it enters the air, and the volume expands, and the water discharged is more, and the buoyancy is greater.

In addition, if you say that you want to learn quickly or improve your grades, I can say that it is impossible. Because swimming is a gradual process, another professional athlete can improve by 0 in a year. A few seconds is a pretty good result.

If you want to learn to swim well, there is only one way: follow a coach who is not rubbish, and then stick to it yourself!!

Because man is clever and nimble.

Learning frogs, man learned breaststroke, and then, intelligent humans improved on the basis and created all kinds of new ways of swimming.

If the hands and feet move reasonably and rhythmically, the water can have a reaction force on the person, allowing the person to move forward without sinking.

And there is a lot of air in the human body cavity, so it is not difficult to float.

Buoyancy = density of water * volume of water discharged by a person * g

Human gravity = human density * human volume * g

The density of people is the density of water.

So, buoyancy "gravity".

First of all, the swimming time should not be too long, and soaking in the water for a long time will cause damage; Continuous swimming for long periods of time can cause muscle fatigue and, in severe cases, muscle fiber damage and pain.

Because the water environment can not meet the needs of health, inflammatory diseases, such as chronic inflammation, fungal infections such as ringworm, and some diseases caused by long-term stagnation such as eczema and erosion.

Long-term swimming is also not conducive to the recovery of arthritis patients, because the water temperature is relatively low, and the humid and cool environment is not conducive to the recovery of arthritis.

Long-term swimming may lead to a decrease in people's resistance due to the cold and humid environment, and induce viral infections such as colds.

There are pros and cons to swimming. In water, we naturally consume a lot of energy, and the flow of water will massage our muscles and help with plasticity.

Compared with the stationary state, the muscles and organs of our whole body are mobilized during exercise, which can temper the functions of our major systems, so it can improve our resistance. Therefore, people who swim regularly tend to be less prone to colds and other illnesses.

Depending on what you want to achieve.

1. If you want to take the test to enhance your physique and forge your body, then you can do it 2 or 3 times a week.

2. If you want to swim**, you need to swim 3 or 4 times a week, and it is best to swim for more than 2 hours each time within the range that the body can bear, because after 45 minutes of underwater exercise, you will start to digest body fat, which is provided by the glycogen stored by the body after 45 minutes of underwater exercise.

3. If you want to become a good swimmer, then 5 to 7 times a week will be better.

Before swimming, you need to make adequate preparations, such as warm-up, because swimming needs to digest the body's very large physical strength and endurance, so we need to put ourselves in the best state to prevent cramps, drowning and other phenomena in the process of swimming, so it is best to swim in a state full of energy, good appetite and sufficient sleep, and the time for everyone to appear in this state is different, so when to swim varies from person to person.

Anything is too much.
