What is Water Polo?

Water polo is a competition between two domestic teams. When participating in this game, 2 teams try to score by throwing the ball to the opponent’s court. A playing team consists of six players and one goalkeeper. The winner will be the one who scores more goals.

This sport requires good swimming and floating skills. Players pass the ball when blocked by the opponent and score by throwing the ball into the net protected by the goalkeeper. Water Polo has many similarities with terrestrial handball. They are sometimes compared to ice hockey because it requires a lot of physical strength.

Water Polo is usually played in a deep pool meaning that the player cannot touch the bottom.

The origin of water polo

The water ball originated from swimming skills shows at fairs and festivals in England and Scotland in the late 19th century. William Wilson was said to be the game developer during this period.

This game was developed under the formation of the London Water Ball Federation and has since evolved in many parts of the world such as Europe, the United States, Brazil, China, Canada and Australia.

Today’s water ball consists of 7 players each (plus 6 substitutes). The ball used for this sport is quite similar in size to the ball in football. However, the ball was made of impervious nylon to ensure the best underwater performance. Previously it was called “water rugby” but later changed to “water polo” in the English pronunciation of The word pulu (meaning ball) in Balti.

For an aquatic volleyball match to take place, there must be players, referees and water balls. The players move under water, pass the ball and throw into the opponent’s goal in a team. Each playing team will have different tactics and lineup like football. However, water balloons are physically demanding and are considered the hardest sport to play.

1. The skills to prepare before entering the game with inflatable Kayak.

Be mentally and physically prepared before kayaking

If you’re new, learn about Kayaks first. Kayak is not only one type but there are many types of boats with all materials including Wooden Kayaks, Composite Plastic Kayaks, Inflatable Kayaks, etc. In which, the line of inflatable Kayaks is becoming more and more popular. Variable by featured compact, safe, flexible, maneuverable.

The boat lines have different narrow designs suitable for each purpose of use, travel kayaks, fishing kayaks, surfing kayaks, sport kayaks, etc.Choose which boat design is mainly based on ability rowing your boat.

New players should choose a quiet water area

Participating in training sessions, kayaking classes (at Kayak sale and rental agents, or Kayak clubs, etc.) are necessary before you decide. Sitting on the boat alone and “going to the sea”. Training sessions will help you gain basic skills on how to balance on a boat, how to row, fix your legs and thighs when rowing, and skills to handle emergencies when on your own boat.


Basic technique and guideline you should know when sailing (Part 3)

Maintain an “inclined angle” with the oar handle by gently pushing toward the bow when the blade surface is open, toward the stern when it is closed.


Lower the paddle’s tongue into the water on one side of the boat, then the other to slow down the thrust.

Start sailing backwards as needed. This is simply reversing the step forward.

Remember to turn your body while paddling backwards.


More than any other factor, the wind has a great effect on kayaking. Any wind above 18.5 km/h (10 knots) affects kayaks. (Water currents can also affect boats.) When on the water, your body or any part of the boat can catch the wind and create resistance. This will affect your speed and direction.

Upwind is the most difficult challenge for rowers. Usually the wind will push your boat in a direction different from the direction you want.

For example, if you want to row in the direction of 12 o’clock, and the wind is coming from the direction of 2 o’clock, the stern will rotate and go straight towards the wind. Therefore, the bow will tilt in the wind.

How does the boat go in the direction you want? Block the wind with rowing steps, for example, perform a rowing step on the other side of the boat. Or you can remove the steering wheel. The rudder is primarily designed to control the stern and keep it from blowing in the wind. You can also use rudder, but rudder is mainly used to minimize wind influence.

In addition, you can also use boats with fins – fixed fins, which cannot rotate like rudders. The fins work like a rudder, but can’t be used to turn a boat, making it easier for you to travel in a straight line when you’re facing strong winds or when one hand tends to use too much force. compared to the other hand when performing the paddle.


Basic technique and guideline you should know when sailing (Part 2)

Visualizing the paddle step is to put the blade of the paddle in the water and push the person over the paddle, rather than pulling the paddle tongue across the water. This helps to push the boat more effectively when sailing.

Stage 1 (catch water): Turn when performing steps of rowing, lowering the paddle into the water from one side of the boat. If the oar blade is placed to the right of the boat, the right shoulder should be inclined towards the bow (forward).

The best place to lower the paddle into the water is in a position parallel to your feet.

Stage 2 (push the boat away): Turn your body when the oar blades push the water back. Use the basics to propel the person over the paddle rather than pulling the paddle’s tongue through the water by hand. This increases the effectiveness, reducing hand and shoulder fatigue.

Stage 3 (return to the position for the next step): When the paddle is lifted out of the water, prepare for the next step with the other shoulder tilted toward the bow of the boat. 

In general, the forward paddle step is a simultaneous, continuous push-and-pull motion – pushing with the upper hand, pulling with the lower hand, which helps to rotate smoothly while rowing.

To add strength, follow the steps below.

Focus on your hands when stretching

Imagine yourself throwing a punch with one hand

Grab the paddle, place one hand on your shoulder

From the shoulder, unleash an imaginary punch for additional force. The vigorous rotation of the body also increases the force.

In general, when rowing, good techniques bring more benefits than the force of the upper body.


What is the simplest way to rotate a moving boat? Just put the paddle blades on one side of the boat underwater. The boat will immediately rotate in that direction – but the boat will sharply decrease its speed when turning.

Kayaking, Rowing

Basic technique and guideline you should know when sailing

This article will guide you on the basic techniques of sailing as progress, rotation and rowing control boat so you can row as you like.

Here are ways to hold the paddle

The distance between your hands when holding the handle of the paddle is approximately equal to the shoulder.

If the distance between your hands is too wide, you will have strong rowing force but quickly tired because the position of this hand requires more effort of the upper body to pull the paddle through the water.

If the distance between your hands is too narrow, then there is a high chance that your steps will have no force.

No matter where you hold the paddle, avoid holding it too tight, which can make you tired, instead, hold it comfortably, open your fingers a bit and hold the paddle moderately.

In each hand, press the forefinger and thumb and form an O-shape to hold the paddle handle comfortably. This is a favorite way of holding down, reducing fatigue, reminding you to push the paddle while padding forward.

When hands are placed in the correct position as follows.

The knuckles point up

Paddle blades erect

Beginners often use unfeathered paddle blades. Although, in windy conditions, the use of “feathered” (angled) paddle blades can reduce wind resistance.

When you pull the paddle out of the water, the wind can affect a flat paddle blade and cause it to catch the wind, creating resistance. Feathered paddle blades have a lower wind-less surface, creating less resistance. 

Most modern paddle handles have a switch in the middle that allows you to turn the oar blades 30 degrees, 45 degrees or 60 degrees. The common rotation angles are 45 degrees and 60 degrees.

Ideal angle? Depending on personal preferences and experience of each person. Most rowers prefer a larger angle because it reduces wind resistance. However, if this angle is greater than 60 degrees, the rower’s wrist will be painful, uncomfortable in the long run.


The step forward is the most basic movement when sailing, involving many factors, not just the arm force. A good stride is made possible by the effort to connect the upper part of the arm and the basic muscles (back, abdomen and glutes). Combining these muscle groups allows you to push the boat efficiently and without causing arm and shoulder fatigue.

Essential steps you should remember when swimming

Let’s have a look at the essential steps and swimming tips you need to know when swimming.

Before entering the water

It takes necessarily about 30 minutes to warm up the body.

Do movements to start muscles and joints. Can do the morning exercise; should practice twice with different intensity.

Run a short distance (100 m) slowly – faster – slower and return to equilibrium.

Continue to activate the joints in the following order: the joints of the neck vertebrae, back support, hip joints (groin), knee joints, ankles, toes, shoulder joints, elbows, wrists, fingers. Perform movement to rotate the joints clockwise and vice versa.

When being in the water

When exposed to the water environment, in the body, there will be a reaction process with 3 stages:

Inhibition (about 10-15 minutes)

Although it has been started to be ready for swimming, but when exposed to water, the body still has peripheral vasoconstrictor reflexes, a slight increase in blood pressure, and the heart. Beats faster, breathing increases and pulse becomes faster.


This is a period of energy consumption, lasting about 1-3 hours depending on the health and training of each person. At this time, the body has begun to adapt to the water environment, the inhibitory manifestations gradually disappear; Your heart rate, pulse, breathing rate and blood pressure are steady and back to their original state.

During this period, movements should be coordinated gently, accurately, and comfortably. When swimming, attention should be paid to avoid swirling areas or currents. Do not swim too far from shore, far from rescue equipment.

Recovery (offset)

At this time, the body has consumed a lot of energy, it should be offset the lost energy. In fact, swimmers will see muscle fatigue, discrete coordinated movements, no longer rhythm, signaling the body needs to rest. Trying to continue swimming will result in secondary cramping or cold.

When feeling tired, swimmers need to slow down, swim to the shore or near rescue equipment, then relax the whole body in a floating position 3-5 minutes and then ashore. If you feel cold, you must go ashore immediately, look for a place with no wind or fire for heating or you can drink some hot sugar tea.

When ashore

Need to rest, relax for 10-15 minutes in a well-ventilated place, then wash again with warm water in an air-conditioned room for 5-10 minutes. Dry yourself and wear warm clothes right in the room.

Pay attention to dry ears, nose, eyes; When necessary, can instill drops. If you’re tired, drink a cup of hot sugar tea.
