Does Core stability training influence spatio-temporal factors of Front crawl and Upper quarter functional stability in Deaf elite swimmers?

The aim of this study was to investigate the effect of core stability training on some of the spatio-temporal factors of front-crawl and upper quarter functional stability in deaf elite swimmers.

In this RCT study, which was a semi-experimental with pre and post-test research design along with experimental and control group; 28 deaf male swimmers who had participated in tournament preparation camp as research samples were divided into fourteen members two groups; experimental (20.92 ± 2.94 Y) and control (20.25 ± 3.41 Y). The experimental group, in addition to continuous swimming exercises, performed six weeks of core stability training program. For measuring of spatio-temporal variables of the front-crawl was used specialized high speed camera (250fp) and for evaluating of upper quarter functional stability was used YBT-UQ test. After checking the normal distribution of the results with shapiro-wilk, ANCOVA test was used to investigate the effect of core stability training program on variables in pre and post-test.

Base of ANCOVA , there was significant difference between result of pre and post-test on record time of 50m sprint front-crawl, swimmer speed, stroke length, stroke index and dominant hand YBT-UQ test, however no significant difference was observed in stroke rate, stroke time and non-dominant hand YBT-UQ test.

Base on the result of this study; core stability trainings have been able to improve swimmers performance and upper quarter functional stability. Therefore, it is recommended that swim coaches use combination of core stability trainings in a swimming practice program.
