ABSTRACT
PURPOSE: The assessment of hip joint abductor muscle strength is most often carried out using a dynamometric test. However, both in clinical practice and literature, evaluation is performed by means of the single-leg half-squat or the amount of abduction movements performed in the hip joint. In this context, the question arises whether the results of individual tests are convergent. The aim of the study is to evaluate the relationship between strength of the hip abductor muscle measured by dynamometer, the single-leg-squat and the number of repetitions of the movements in time. METHODS: A group of 35 students (20 women and 15 men) between 20 and 24 years old participated in the study. Each student was subjected to three tests assessing the condition of the hip and associated abductor muscles. Those included: assessment of hip joint abduction muscle strength in a dynamometric study, assessment of the number of abdomen movements performed lying on the side and standing, during a 30-second interval, and the single-leg-squat test. RESULTS: Based on the tests conducted, a significant relationship was observed between the muscle strength measurement results for the left and right side in the dynamometric study and the number of hip abduction repetitions in 30 seconds and the single-leg-squat test. CONCLUSIONS: The obtained results indicate a significant relationship between the results of all the tests. In practice, this means that the tests can be used interchangeably.
