Abstract

Sports training is a way to raise the level of players physically and mentally , so that they can exercise events and athletics effectively and efficiently to achieve the best results and achievements , and training in accordance with the distances determined in advance to achieve them through training depending on the weight of the tool help to achieve the required achievement in key races is one of the modern training trends Turn them that researchers can not be applied experimentally training Bemba target distances unless the athlete has a cognitive process , considering that the target related to visual perception distances. The research aims to identify the targeted javelin throwing from different positions throwing distances and weights different tool for archers young spear through training, and to identify the effect of throwing according to the target distances of different positions chucking and weights different tool to develop the starting variables Elkinmetekih visual perception and achievement for archers young spear. Applied research on the (10) players from clubs province of Najaf athletics and who practice the effectiveness of the javelin to the category of young people, were sprains coefficient measurements Anthropometric account, were divided randomly into two groups (control group, experimental) (5) players each group was conducted parity to the two sets of Search in the study variables (cruising speed, angle of departure, high starting point, visual perception, achievement), It was variables account through test achievement was filmed for calculating the starting variables , as well as test cognition , was especially according to training and target weights for distances of the different tools that are related to the technical stages of performance status and the duration of the exercises within the setup period and part of the competition by (4) and unit training a week , It was the time of the exercises in part of the Section President within the module ranges between ( 30-40 ) minutes in the days of throwing all , progress training progress through pregnancy training was gradually for three weeks, the fourth week low pregnancy and so on , which is progress 3: 1 , and included drills (24) and training module for each weeks , since the application of the exercises took 6 weeks for your preparation , were determined distance (50 m) as a space targeted by the legal instrument ( shaft 800 grams ), the experimental group was the intensity of training modules ranging from (70% -110 % ) and on target according to distances . Were identified target distances for all weights during training modules according to the target of legal tool for distance , The results showed that evolution incident to the variables of the starting Elkinmetekih ( cruising speed , angle of departure , high starting point ) and variable visual perception experimental group , which was the focus of the proposed training intensity through the distances target different weights led to integration in motor performance and came in line with what was achieved and thus get the best achievement of the control group , which rehearses the usual manner .
