The effect of Rondo chains with weighting on some bio-motor abilities of advanced Football players

Abstract

Through the researchers' follow-up of the Kerbala clubs, they noticed a weakness and deficiency in the level of bio-kinetic abilities and in most of their elements, in addition to handling the ball and sometimes the inability to make the right decision. This indicates a clear weakness in terms of sufficient attention to bio-kinetic abilities. The study aimed: to prepare rondo chains with weighting. For advanced Football players, Identifying the effect of rondo chains on some bio-motor abilities of advanced Football players. The researchers used the experimental method by designing two equal groups with pre- and post-tests. The researchers defined the research population as the players of the Karbala second-class clubs applying for the season (2023-2024), who numbered (9) clubs. The researchers chose the research sample intentionally, represented by the 27-player fan club. The researchers divided the sample by a simple random method (lottery) into two groups, experimental and control, and each group contained (10) players after excluding (7) players. As a exploratory experiment, rondo chain exercises were used. With intensity (85-100%), the training continued for a period of 8 weeks, at a rate of 3 training units per week.
