The effects of the press and role-exchange exercises using the competitive style on some physical variables for handball players
Abstract
The current study aims at: Identifying the statistical significant differences of some physical variables for the handball players between the pre-test and the post-test of the experimental group. Identifying the statistical significant differences of some physical variables for the handball players between the controlling and the experimental group in the post-test. In order to verify the objectives of the research, the researchers put forwards the following: There are significant differences in some physical variables for the handball players between the pre-test and the post-test for the experimental group in favor of the post-test. Identifying the statistical significant differences of some physical variables for the handball players between the controlling and the experimental groups in favor of the experimental group. The researchers used the experimental methodology as it suits the nature of the research and the experiment was conducted for a sample that includes AlFotuwwa club handball players, whom were tested using the deliberate method and divided randomly into two groups (the experimental and the controlling groups) and each of the groups consisted of (10) players for each group. Homogeneity and equivalence were achieved in the two groups of the research in terms of the (age, height and weight) variables, in addition to the variables determined by the relevant specialists. The experimental design that is called the design of the controlling group with random selection with pre-test and post-test .The procedures of the research involved press and role-exchange exercises with a competitive style and these exercises were applied to the experimental group. In light of the results reached, the researchers drew the following conclusions: The press and role-exchange exercises using the competition style developed all the physical variables through comparing the results of the pre-tests and post-tests of the experimental groups. The program prepared by the coach resulted in developing the power distinguished by speed for the arms The experimental group, which used the press and role-exchange exercises with the competitive style achieved a better development than the controlling group, which used the program prepared by the coach, in terms of all the physical and skill variables tackled by the research and that was through comparing the results of the post-tests of the experimental and the controlling groups.
