Abstract

Hypothesis: To determine the effect of receiving the visual feedback of the sphygmomanometer on lumbopelvic motor control (LPMC) tests in professional swimmers.

Method: 31 professional swimmers to participate in the study. The outcome was maximum absolute mmHg variation in the pressure biofeedback unit's manometer with and without visual feedback on four LPMC tests.

Results: Test scores were significantly affected by visual feedback F = 10.07, p = 0.002, η² _p = 0.117 and the type of test F = 32.53, p < 0.001, η² _p = 0.300.

Conclusion: Visual feedback has a positive effect on the Active Straight Leg Raise Test (ASLR), the Knee Lift Abdominal Test (KLAT) scores completed by professional swimmers.
