The main aim of the research is knowing the differences between the jump serving in volleyball game and the far shooting skill in jumping in the handball game.
The importance and need for the research arises, in studying the most important biokinematic variables to perform the jump serving in volleyball game and the far shooting in jumping in handball game, to provide an amount of specific information for both skills for the researchers in the studies of transforming the impact and generalized the motor programs between these two skills,because these informations have an impact in identifying the stages which help in transforming the effective impact through learning operation between these skills.
The researcher have chosen the subjects on purpose representing six players from the national teams,three of them are volleyball players and the other three are handball players. The exploration test is done on 2352012 ,then the main test is done on 2752012. The researcher have used a video camera of 25 photsec.These results have been analyzed and got the biokinimatical variables by Dartfish program.
The researcher have got many result . The most important result is appeared the random differences in( impulse angle , launching , approach, knee and hip)variables. Where as spiritual differences for the jump serving in volleyball in (speed, the shoulder angle,the ball launching angle, the approach steps speed, the hip hight in the moment of leaving the ball and the totaltime of performance). Where as spiritual differences are appeared for the far shooting skill in jumping in the handball in the ball launching speed variable.
The two researcher have many recommendations. The most important are the necessity of emphasis the teachers and coaches on making the transforming operation of the impact of learning between the jump serving skill and the far shooting skill in jumping in the impulse angle, launching, approach, knee and hip variables,because of the similarities between the two skills in these variables. The necessity of stressing on cutting the impact transforming between the jumping serving skill and far shooting skill in jumping in the ball launching angle,angular speed of shoulder, ball launching speed, the approach steps speed, the hip hight and the total performance time because of the unsimilarity of performance between the two skills in these variables . |
