The effect of gradually decreasing the training volume (Tapering) in different proportions on some physical characteristics of futsal players

The research aims to identify the effect tapering in three different proportions (30%, 50%, 70%) on a number of physical variables between the pre- and post-tests for the research sample, and to identify the differences in a number of physical variables in the second post-test. Among the experimental groups.To achieve this goal, the researchers assumed the presence of significant differences between the pre-test and post-test for a number of physical characteristics after the experimental group implemented a reduction in training volume by (30%, 50%, 70%) and the presence of significant differences in the second post-test for the experimental groups.The researchers used an experimental design with three equivalent groups.The research sample consisted of 18 youth futsal players. The research sample was divided into three groups based on their physical levels. The first group implemented the tapering program with a reduction rate of (30%), and the second group implemented the tapering program with a reduction rate of 30%. (50%), and the third group implemented the gradual decrease program at a rate of (70%) in (4) training units per week.The researchers used the following statistical methods:(Arithmetic mean, standard deviation, T value for correlated samples, ANCOVA value for analyzing differences between the three experimental groups).The researchers concluded the following, The reduction percentage (50%) showed a development in all the physical characteristics of futsal game (flexibility, explosive power, motor speed, agility, strength characterized by speed, transitional speed, speed table), while the reduction percentage (30%) showed a development in physical attributes (flexibility, explosive power, and strength characterized by speed), while the reduction percentage of (70%) showed a significant improvement in physical attributes (flexibility, explosive power, motor speed, transitional speed, and speed table), while no significant improvement was shown in Characteristic of motor response speed after a period of gradual decrease in the three reduction rates (30%, 50%, 70%).
