On how the selection of outstanding talent long jump


long jump and triple jump,ralph lauren paris, long jump, including two projects belong to the explosive force of nimble project, technical architecture chosen by the run, jump, fly and floor components, the athlete's speed, speed-strength, dexterity and other physical fitness are have a very high demand, especially for body shape has special requirements.
First, the body weight requirements
tall shape, weight, leg length, body circumference and width of the small, upturned like the hip muscles were tight, long the Achilles tendon, the arch is high, short toe Qi powerful, flexible soles.
long jump is a movement to overcome its own weight, so weight has a greater influence on the results, which requires athletes to height and body light, so to overcome the body's gravity, vault higher, more conducive to the long jump. Another athlete's body have a certain impact on the long jump, tall, short torso,abercrombie paris, long legs in training have a greater potential for long jump the athlete's lower extremities and the ratio of height and muscle development in various parts of the body of the former affect the movement magnitude and location of the body center of gravity, the latter part of the activities related to the ability of the body. Study abroad was the length of the longest leg is the long jump athletes, accounting for 51.5% of height, the specific form of indicators can be used Ketuo Lai index (weight / height × 1000) to be reflected in comparison.
Second, movement qualities and personality traits
technology and quality of movement is closely related technology is built on the basis of the quality movement. Good athletic ability, jumping into the technology of the master, under intensive training and intense competition, increasing athletic performance, prevent injury, and extend the campaign life are important. In particular, absolute speed, jumping ability and speed-strength, movement quality is the main jumping athletes, is the selection of key indicators.
absolute speed: jump sport requires a strong high-speed run-up to accurately complete the jump. In the run-up speed to establish the basis of only the absolute speed is an important factor in decision to jump performance. Project start using standing height of 30 meters, far-degree program starting 60 m using stand-test absolute speed.
jumping ability and speed-strength: Select a standing long jump, standing triple jump, the net run-up Mogao jump height, five four-step run-up stride long jump and shot put after throwing five tests, they can reflect the athlete's jumping ability, speed strength and body coordination, and with the jumping events although there are common characteristics, but the movement of each item, there are different forms and requirements, the requirements of the sport are not the same quality, selection should not only attach importance to the overall development level of athletic ability, but also consider the different characteristics of the project focused, long jump and triple jump, focus on the standing long jump, standing triple jump and long jump four-step run-up five stride.
Third, the physiological indicators
characteristics of the project requires athletes to jump in a short time to maximize the physical potential, we must have fast speed, but also have great power, and the two organically combined. Therefore, the great strength of muscle activity, the cerebral cortex dominant excitatory process. Selection has generally adopted a step test measured the heart work index. Cardiac function index is a quantitative function of the load test is a reflection of the level of the body an important indicator of heart function. On a small table when the pulse rate, systolic force that big, strong heart function; immediately after exercise pulse rate less that complete quantitative load occurs when the heart function to save the phenomenon; fewer pulse recovery, restore heart function that quickly . The smaller the heart work index, indicating that the heart function better.
long jump requires athletes to feature in a short time to maximize the physical potential to create the largest outbreak of the power take-off, focus on the muscle force and explosive force demanding fast. Long jump off of the muscles involved in movement: nervous - muscular system to reflect the explosive way to complete compromise so long, restrained shrinkage, swing leg swing, the integrity of the braking power, coordination,abercrombie france, consistent, complete a take-off action to achieve the standard take-off . Rapid contraction of white muscle fiber characteristics and muscle fiber is composed of a priori during training can not change the red muscle and the percentage of white muscle composition, selection of specialized equipment available at the time, measured by the ratio of leg white muscle fibers. Another athlete with a step test measured the heart work index, to the selection effect.
indicators in addition to the appeal, should take into account the athlete's mental situation. Athletes with high levels of intelligence to better understand the coach's training requirements, intent, can think better, understand the action; there are athletes physical maturity: early in the physical capabilities of young people, although stronger than the late-maturing, but is a temporary phenomenon, often late even greater potential, easy to reach high levels.
Finally, psychological
psychology plays in regulating the movement, control, and a leading role, a good physical and mental quality is the prerequisite skills to full play to the conditions. Jumping movement due to technical complexity, in the air to complete a series of actions, as well as a springboard from the constraints of the athlete's psychological requirements are particularly high. Selection must attach importance to psychological testing and inspection, selecting the nervous system more flexible and dynamic response as a particularly fast, the space body feels good, directional ability,birkenstock paris, there is a strong aggressive player.
