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. Below, I will share the knowledge of rowing terms for you, hoping to help you!

space

(Stroke distance)

Technical terms of rowing. Refers to the distance that the boat moves with each paddle in the race, that is, the whole race is divided by the number of paddles rowed by the boat. For example, the whole rowing race is 2000 meters, and a boat paddles 250 paddles, which means that the pitch of each paddle is 8 meters. Therefore, the stroke distance reflects the effect of athletes' stroke, which is related to the athletes' stroke width, stroke frequency and other factors. Beginners and young athletes should emphasize the rowing distance and improve their rowing skills from the segmentation effect of each paddle.

Stroke cycle

(Stroke cycle)

Technical terms of rowing. Refers to the whole process of rowing. The rowing cycle of rowing boat consists of entering, separating, discharging and returning. From the athlete's movements, it is to lift, pull, press and push the paddle. The whole rowing cycle is continuous and uninterrupted. If you paddle 40 paddles per minute, the cycle time of each paddle is about 1.5 seconds. Paddling rhythm: the technical term for rowing. Refers to the ratio of speed and strength in each stage of a rowing cycle. In a rowing cycle, it is usually required to pull quickly and slowly, pull hard and relax when pulling back. For example, suppose 40 paddles per minute, then the period of each paddle is 1.5 seconds. Rowing rhythm requires 0.5 rowing? 0.6 seconds, and it takes 0.9- 1 second to return the oar. The rhythm of rowing is a sign of the rationality of athletes' skills.

Rear paddle

(recovery)

Technical terms of rowing. After the paddle comes out of the water, the athlete pushes the paddle handle forward briskly and smoothly with both hands. When the arms are completely straight and the paddle handle pushes over the knee, the slide seat moves forward, and the upper body naturally moves forward to the preparation posture of the next paddle. During the whole process, the blade moves forward horizontally in space, leaving the water surface about 15? 20 centimeters. When pulling back, the body should be stable, natural and relaxed, and the movement is relatively slower than the pulling speed. The time ratio of pullback and pullback is about 2: 1. If the period of an oar is 1.5 seconds, it takes about 0.9 seconds to return to the oar. L seconds, paddle 0.5? 0.6 seconds. Because of the relaxation when paddling, athletes can get a short-term physical recovery every time they paddle. Therefore, it can be considered that paddling and paddling are alternating between relaxation and exertion.

Li Zheng

(positive force)

Technical terms of rowing. All kinds of ships are driven by engines and sails. Whether it is a propeller driven by an engine or a sail fluttering in the wind, its power is endless. The propulsive force of rowing is intermittent, because when an athlete paddles, the paddle produces a powerful effect in the water, and then produces a positive force to push the boat forward. This is positive force. When the paddle comes out of the water, the ship relies on inertial force, and the positive force disappears here.

Negative force

(negative force)

Technical terms of rowing. The propulsion of rowing is different from that of other ships. When an athlete pulls the paddle, the paddle can generate positive propulsion in the water. However, after the paddle leaves the water, there is no propulsion, and because of the movement of the slide and the change of the body mass direction, it has a great negative force on the ship, which is a negative force on the advancing ship. One of the marks of rowing skills is to limit the role of negative forces and make full use of positive forces.

paddle

(driving, boring)

Technical terms of rowing. After paddling into the water, the athlete's weight is forcibly transferred to the pedal frame through his legs, and at the same time, the athlete paddles actively with all his muscles. Judging from the sequence of muscle force, it is generally believed that pulling oars mainly depends on leg strength at first, then back muscles, and finally shoulders and arms. When starting to kick the paddle, the slide seat moves to the bow on the slide rail. At this time, athletes are required to make full use of their own weight, just like hanging on the paddle handle, in order to transfer all their strength to the paddle. On the other hand, the smaller the movement of the paddle in the water, the better the rowing effect. In the whole rowing cycle, rowing stage is the power stage to promote rowing, so athletes should give full play to their physical fitness.

Flat paddle

(eclosion)

Technical terms of rowing. This means that athletes put their oars flat on the water. When the paddle is flat, the athlete's body relaxes, the back of the paddle touches the water, and the front of the paddle faces the sky. The flat paddle is also a password, which can be used by the helmsman or coach when an athlete encounters obstacles or needs to stop paddling when approaching the dock? Flat paddle? Password, tell the athletes to stop paddling.

Inverted oar

(Backwater, reversing)

Technical terms of rowing. When rowing normally, the athlete puts the paddle into the water, pulls the paddle with the front end of the paddle, and the boat carries the athlete forward. When the paddle is inverted, on the contrary, the athlete puts the paddle into the water, pushes the paddle with the front end of the paddle, and the boat paddles in the direction in front of the athlete, that is, the tail. Inverted oars are usually used in departure, berthing or other emergency situations.

Paddle lifting

(elevator)

Technical terms for rowing. When the paddle rotates to an angle perpendicular to the water surface and the paddle is inserted into the water from the water surface to the paddle neck, lift the paddle handle immediately. The center of gravity of the human body moves backward quickly from the pedal, and the arms and back muscles are pulled hard at the same time. It is the first stage to exert force in periodic paddling, which requires quick and powerful action to tie the water support point and push the ship forward by the reaction force of the water support point.

Press the oar

(Reporter)

Technical terms for rowing. After the paddle is pulled, the legs are pushed straight on the swimming lane, and the trunk leans back about 35 degrees in the vertical position of the slide seat. Bend your arms to the diaphragm, gently grasp the paddle handle with your palm and move to the abdomen, and press the wrist in an arc shape, so that the paddle can quickly come out vertically. It needs to be neat, fast and light. Otherwise, the blades will sweep the water and affect the speed. This is the preparation process for rowing to enter the second cycle.

Paddle into the water

(entry)

One of the technical terms for boating. After the athlete returns to the paddle, his arm naturally leans forward completely, that is, the front of the paddle has turned from upward to forward, and the paddle is perpendicular to the water surface or slightly forward. Using the weight of the paddle head, the two arms and hands are naturally lifted at the same time, so that the paddle cuts into the water, forming the optimal depth for the paddle and the paddle neck to dive into the water. At this time, the athlete can quickly make the paddle catch the water by lifting his body and pulling his arm, and at the same time completely transfer his own weight and strength to the pedal frame, so that the boat can be pushed forward by force. Entering the water is the beginning of a rowing cycle, which requires quick action rather than excessive force, and does not require splashing.

Release; Emissions; issue

(release)

Technical terms of rowing. At the end of pulling the paddle with both legs straight, tilt the paddle back and forth about 25 degrees, and at the same time bend the arm to pull the paddle to the diaphragm. At this time, lightly press the paddle handle with the palm of your hand and the root of your palm to make an arc turn, so that the paddle can jump out of the water vertically and quickly turn to a horizontal state. This action of turning the paddle requires gentleness and quickness, so that the paddle will be clean when it comes out of the water, and there will be no phenomenon of picking water or stopping running. Because after rowing, the ship gained propulsion and was gliding at the fastest speed. If the speed of the paddle moving out of the water is slower than that of the ship, it will form a paddle to block the water and affect the forward speed of the ship.

Paddle frequency

(speed)

Technical terms of rowing. Refers to the number of paddles per unit time. That is, the number of paddles in the whole game divided by the performance of the game. From the biomechanical point of view, the speed of the boat is determined by the rowing frequency and the rowing distance. These two variables are influenced by technology and equipment. Therefore, we can improve the speed of the boat mainly from two aspects: rowing distance and paddle frequency, but we can't increase the paddle frequency indefinitely, and we can't reduce the effect of rowing in order to improve the paddle frequency. The paddle frequency of rowing competition ranges from 30? 40 paddles per minute. The rowing frequency of men's eight-person rowing is the highest, especially when sailing, even as high as 48 paddles/minute. In training, different stroke frequencies can often reflect different training intensity.
