Abstract

The research aimed to use rubber bands to achieve practical blood flow restriction (PBFR) and measure its effect on the anterior and posterior quadriceps muscles on the increasing in systolic blood pressure associated with high training intensity during the performance of the squat lift skill by nine strength athletes in some clubs within Baghdad city, whose ages were (19.25±0.89) years.
The researcher used an experimental method of experimental and control groups design. The experimental group performed squat skill exercises with (PBFR), while the control group performed the same exercises without blood flow restriction.
The SIG value for the Wilcoxon statistical coefficient for the experimental group before performing the exercises (0.043 ≤ 0,05) and after performing the exercises (0.042 ≤ 0,05) showed a statistically significant difference due to the blood restriction by rubber bands, favoring the post-test results for measuring systolic blood pressure. While the SIG value for the control group before performing the exercises (0.59 ≥ 0,05) and after performing the exercises (0.66 ≥ 0,05) didn’t show any statistically significant difference due to unrestricted blood flow by the rubber bands in the selected muscle during the practical performance of the squat lift skill exercises. The researcher recommended using the rubber bands for (PBFR) for the arm muscles during the bench press skill and using other exercises performed by the legs for the deadlift skill.
