The effect of enhanced dimensional activation exercises using weight belts on the maximum transition speed of 50-meter freestyle swimmers

The study aimed to reveal the differences in maximum transition speed between the experimental group, which would apply enhanced post-test activation exercises, and the control group in the post-test. To verify the research objective, the researcher hypothesized that there would be statistically significant differences in maximum transition speed between the experimental and control groups in the post-test. The researcher used the experimental method because it was suitable for the nature of the current research. The research was conducted on a sample that was chosen purposively, which consisted of the Iraqi national team swimmers in the advanced category, numbering (10) swimmers. They were randomly divided into two groups (experimental and control) with (5) swimmers for each group. The researcher used the experimental design called the (equivalent groups) randomized test design with pre-test and post-test. The researcher also used (content analysis, tests and measures) as means of collecting data. Homogeneity was achieved between the two research groups in the following variables (age, height, weight, and training age), in addition to conducting equivalence in the physical variable under investigation.

The research procedures included designing enhanced post-activation exercises. The pre-physical test was conducted, and then the enhanced post-activation exercises were performed using weight belts on the experimental group, while the control group performed the special warm-up by the team coach with traditional equipment. The implementation of the training program took (6) weeks, from 4/1/2025 to 12/2/2025 during three medium cycles, with (2) minor cycles and with a wave (flat loading), with (4) training units per week (Saturday, Sunday, Tuesday, and Wednesday). The exercises proposed for the research were applied in the (Al-Shaab International / Baghdad) swimming pool. After that, the researcher conducted the post-physical test with the same procedures and steps that were followed in the pre-test.
