The research aims at investigating:
- The effectiveness of physical exercises, using (2%) additional weights to the first experimental group, on a number of skillful variables for youth football players.
- The effectiveness of physical exercises, using (4%) additional weights to the second experimental group, on a number of skillful variables for youth football players.
- The effectiveness of physical exercises, using (6%) additional weights to the third experimental group, on a number of skillful variables for youth football players.
- The differences in the number of physical and skillful variables for youth football players in physical exercises by using ratios (2%, 4%, and 6%) of additional weights.
Research Hypotheses:
- There are differences that have moral significance, between the pre-test and post-test of the first experimental group, by (2%) in a number of skillful variables of youth football players.
- There are differences that have moral significance, between the pre-test and post-test of the second experimental group, by (4%) in a number of skillful variables of youth football players.
- There are differences that have moral significance, between the pre-test and post-test of the third experimental group, by (6%) in a number of skillful variables for youth football players.
- There are differences that have moral significance among the three experimental groups, in a number of skillful variables for youth football players.
The researcher used the empirical method, because it corresponds to the nature of this research; the samples of the research are the youth football players of North Gas Sports Club, in (2014-2015) sport season. The players are 24 ones in total, divided into three experimental groups; 8 players for each group. The ratio of the additional weights used for the first group is (2%), and the second group used (4%), while the third one used (6%). Balancing the variables: (training age, length, and the mass of the body), is made in the research for the three experimental groups; in addition to balancing the skillful variables in the research. Concerning the key steps, they were as follows: conducting questionnaires and interviews with specialists, so as to determine the ratios of the additional weights, as well as standardizing the physical exercises and determining how much they fit to the samples of the research. The key steps of the research also comprise the designing of the training program. The researcher conducted the pre-tests for the physical and skillful variables in three sequent days. After that, the training program was applied for two mid-cycles at (1:3) undulating motion, as eight short cycles. The pre-test and the post-test of the skillful variables were conducted in the same procedures adopted in conducting the pre-tests.
Conclusions:
- The training program applied to the three experimental groups, that used different ratios of the additional weights: (2% for the 1st group, 4% for 2nd group, and 6% for the 3rd group), achieved a moral advancement in the whole skillful variables adopted in the research, which are: (dribbling, far shooting, medium pass, ).
- The training program achieved a significant advancement, in the whole skillful variables in the research, to the 3rd experimental group that used (6%) additional weights, more than that is achieved to the 1st group that used (2%), and that is achieved to the 2nd group which used (4%) as well. As a result of the correlation between the physical and skillful aspects, the results of the 3rd group became more advanced in the physical variables, so the group became more advanced in the skillful aspect.
- Using the repetition training method is effective in developing the level of the skillful variables by using physical exercises in different ratios of additional weights; because the used intensities highly correspond to the characteristics of the game, in addition to kind of the recreation used in this method which is complete one; subsequently it provides the players with the possibility of total recovery by reconstructing the energy stores by a large margin.
Recommendations:
- Football coaches are recommended to use the repetition training to develop the physical aspect of the players by using a ratio of additional weights due to its effectiveness; as well as the coaches must provide the players with a period of time in which they could recover, and restore energy sources.
- Conducting similar studies on other sport activities, in different training methods as well. |
