Rowing is an important event in water sports, which coincides with the Olympic Games. What do you know about boating? Let me tell you about boating.

Rowing knowledge:

Rowing is one of the traditional events in the Olympic Games. Rowing is a water sport. One or more rowers sit on the boat with their backs to the direction of the boat, and use their muscle strength to paddle through the simple leverage of paddles and paddles to make the boat move forward. A ship may or may not have a helmsman.

Rowing is mostly carried out in natural waters such as rivers and lakes, with fresh air and plenty of sunshine. Bathing in nature can effectively improve the cardiovascular and respiratory functions of human body, enhance the muscle strength of the whole body, adjust the balance of nervous system, and help to improve the health level of human body.

The vital capacity of rowers ranks first in all sports, reaching 7000 ml. Some people call boating lung gymnastics.

At the beginning of the rowing competition, the boats lined up at the starting line. After the starter gave the order, the ship rowed to the finish line at the fastest speed, and the result of the race was judged by the order in which the bow reached the finish line.

In natural waters, the weather will have an impact on the results of the competition, and even the weather will change before and after the two groups of competitions, so the results of the competition are not absolutely comparable. So there is no world record for rowing performance.

This sport must be played on calm water. From the starting point to the end point, it should be a direct channel with the same width. The waterway is 2000m long and13.5m wide. Generally, there are 6 channels, with a maximum of 8 channels.

In addition to the 2000-meter race distance, the race channel also has appropriate preparation waters. At least 100 meters of free water is left outside the finish line. There should be safety warning waters on both sides of the waterway that are equivalent to the width of the waterway.

Rowing lanes are divided by buoys connected in series. Buoy spacing is10m or12.5m.. The surface of the buoy should be soft and the diameter should not exceed15cm. The colors of buoys in the whole channel are regularly distributed.

The buoy is red from the starting point to100m, orange or white from100m to1750m, and red from1750m to the ending point. There should be obvious distance signs every 250 meters on both sides of the whole track.

Departure Tower Departure Tower is a special facility for rowing competition. At the beginning of the rowing competition, the athletes' boats are arranged behind the starting line, and the starting referee and the boat picking referee at one side of the starting line are responsible for aiming the bow of each boat at the starting line, and the starter stands on the specially set starting tower.

The departure tower is located 30 ~ 50 meters away from the departure route and on the extension line of the center line of the waterway water area.

In order to let the boat athletes clearly see and hear the starter's signal, the starting platform on the tower for the starter to work should be at least 3 meters above the water, but not more than 6 meters. When the flag-raiser signals all the boats to line up with white flags at the starting line,

When the order is given, the starter will start to call the roll one by one. At the end of the roll call, the starter shouted "attention" in English, and then raised the red flag. Shout "Go" at indefinite intervals and wave the red flag at the same time. The athletes saw and heard the orders.

After the rower gives the signal, he can set sail and the race begins.

If a ship leaves before the "departure", it is a sea grab. In case of hijacking, * * * will start again and give warning and punishment to the hijacked ship. Because the starter stands condescendingly on the starting tower, he can find and deal with all kinds of accidents when athletes start in time.

Agsostart starting system, also known as "Qi Qi controller" or "starter" for short, is a special equipment for rowing competition. This controller has a one-arm baffle on the starting line of each channel, and the baffle is concave.

Before starting, the athletes lined up the top of the boat in the depression of the baffle, and at the same time of giving a sound starting command, the baffle fell into the water. If the ship is robbed, the top of the ship will bounce back to the baffle to avoid the phenomenon of artificial rescue in the past.

Qi Qi controller is an electro-hydraulic device, which was first used in canoeing competition. Rowing was introduced in 1995, and was officially used in Atlanta Olympic Games in 1996.

The system is started by light. Each departure platform is equipped with two lights, red and green. When the starter gives "attention", the red light will be on, and when the start signal is given, the green light will be on and the game will start.

At the same time, in order to indicate the end of the navigation area, two white flags should be placed on both sides of the channel at 100 meters to mark this boundary. From the departure route, every 250 meters in the middle, buoys of different colors should be used to indicate this distance.

There are no buoys at the departure line and the finish line. At least 5 meters on both sides of the channel outside the finish line, two large white buoy water drums are set, and a red flag is fixed on each water drum to indicate the end of the channel.

Rowing equipment:

Competition equipment ship

dugout canoe

Rowing is a kind of boat specially used for competition and training. The boat is long and narrow, with sharp and thin ends, like a woven shuttle. In addition to high-quality wood, rowing boats are made of FRP, aluminum alloy, carbon fiber and other materials.

The longest eight-person captain17 ~18m is only 57cm wide. The smallest single length is 8 meters and the widest point is only 29 centimeters. See table for rowing specifications.

oar

oar

Paddle is the accessory equipment of rowing boat, and it is the main tool for athletes to paddle the rowing boat forward, which is divided into double paddle and single paddle sweeping paddle.

There are two kinds of paddles. Made of high-quality wood or carbon fiber or a combination of two materials.

One end of the racket is a round rod for the player to push and pull the racket after holding it, which is called the racket handle; At the other end is an oar in the shape of a shovel. The size and shape of the blade are very important.

The success of rowing equipment reform lies in the use of axe-shaped paddles, changing the paddle surface into axe-shaped paddles and increasing them. Using the same force on the paddle handle will produce greater propulsion.

safe conduct

bowling

The rowers turned their backs to the forward direction and couldn't see the situation in front of the row. In order to reduce accidents safely and as far as possible, the rules stipulate that a white ball with a diameter of 4 cm and made of soft rubber or similar materials must be installed at the bow of the rowing boat as a protective measure. This ball is called a safety ball.

rowlock

Paddle rigging

In early rowing, there was no paddle rack, and only two arms were used to pull and swing the upper body to paddle. There are many structures and forms of paddle racks, usually 4 ~ 5 aluminum alloy thin tubes are combined into a paddle rack.

The outer end of the paddle frame is a paddle ring similar to a paddle fork, which can be opened and closed. The paddle is placed between the paddle rings, and the paddle is in the water. When an athlete paddles, the force is transmitted to the paddle shaft, which pushes the rowing boat forward through simple leverage. The paddle frame on the twin-paddle boat is symmetrical, while the single-paddle boat is staggered.

Pedal frame

Stretcher worker

When the athletes paddle hard on the boat, the pedal frame gives them a good "foothold" There are special sports shoes for athletes on the pedal frame.

This kind of shoes should not only make the athlete and the boat relatively "firmly" combined, but also make the athlete push and pull the paddle freely. There is a string connected to the pedal at the heel. In the event of an accident or capsizing, athletes' feet can fall off quickly, which is called "quick-release" shoes.

Putting the pedal frame too close to the bow will cause a large inlet angle and a small outlet angle; If it is too close to the stern, it will cause a small inlet angle and a large outlet angle. Therefore, the correct placement of pedal frame can ensure that athletes have correct ending posture and reasonable paddling range.

slide

Sliding seat

The slide seat is also called the seat board. There are four wheels that can rotate flexibly under the seat plate. Rowers have high requirements on the wheels of the slide, and they should not be loose or excessively worn, and they should not slide because of the difference of wheels.

The use of sliding seats can give full play to the strength of rowers' backs and legs.

slide

rail

There are two slide rails parallel to the longitudinal axis of the rowing boat below the slide seat, and the four wheels of the slide seat move back and forth on the slide rails. For rowing boats of different ships, the spacing of slide rails is different, such as width 18cm, 23cm and 28cm.

The length of the slide rail varies from 65 cm to 85 cm. In order to ensure the effective length of rowing, the length of the slide rail is generally 70cm ~ 85cm, and the length from the top of the slide rail near the bow to the horizontal line perpendicular to the paddle bolt is not less than 65 cm.

Stabilizing rudder

Fin rudder

Rudder stabilizer is a fixed device for the lower part of rowing boat hull. Because it looks like a fish fin, it is also called a fin rudder. Rudder stabilizer is generally made of metal and installed on the longitudinal axis below the hull, close to the stern, which plays a stabilizing role in rowing without manual manipulation.
