First, the factors that restrict the prediction ability of young handball players
Foresight ability is an important part of athletes' sports intelligence, which restricts the exertion of athletes' competitive level and the outcome of the competition. However, athletes' sports intelligence is influenced by congenital genetic factors, life factors and training factors. When selecting handball coaches, priority should be given to the cultivation of young people who are naturally flexible in neural process, quick in conversion, quick in response, strong in acceptance, strong in collective honor, strong in adaptability to fierce competition for ball rights, strong in antagonism, strong in awareness of offensive and defensive conversion, and quick in training, and attention should be paid to cultivating their on-court prediction ability.
Second, measures to cultivate the predictive ability of young handball players
(1) Teach young handball players handball technical and tactical rules and cultivate their predictive ability. The rules of handball techniques and tactics exist objectively, and are not transferred by people's will. People can only understand and apply them through practice. Coaches should pay attention to the movement structure of handball skills and tactics when teaching basic skills and tactics to young athletes, so as to help them understand and master the methods and technical requirements they have learned. Taking the common offensive catch technique in handball as an example, the structure of this technical action is composed of catch opportunity, grab position, catch action and catch attack. However, many coaches only pay attention to teaching small players the catching action and attacking skills, but ignore the teaching and training of catching, grabbing the position and getting rid of the ball. It is common for some small players to run the ball blindly on the court. When they encounter man-to-man defense or tight defense, they will not seize the favorable position of catching the ball, or "run backwards" to get rid of the defense to catch the ball, which leads to their frequent catching mistakes.
(2) Strengthen the stereoscopic vision of young handball players and cultivate their predictive ability. Vision consists of eyes, optic nerve and visual center, which can be divided into central vision and peripheral vision, and is the main source for athletes to obtain external information. The vision when both eyes gaze at an object at the same time is called binocular vision, which can observe the three-dimensional space of the object and produce stereoscopic vision If people's stereoscopic vision is not perfect, it will reduce people's sense of time and space, so that people can't accurately complete the actions such as passing and shooting in attack, and can't accurately distinguish the position relationship between themselves and their teammates in defense, and can't accurately predict the possible changing trend of their offensive and defensive situation with the transfer of the ball, so as to take corresponding countermeasures in advance.
