Optimal and maximal loads during hip adduction exercise by asymptomatic people

Abstract

[Purpose] The purpose of this study was to provide data for decision making regarding the optimal and maximal hip adduction loads for clinical and fitness purposes, respectively. [Subjects] Forty-eight (24 males, 24 females) asymptomatic adults participated in this study. [Methods] Subjects performed optimal and maximal hip adduction loads. Regarding the gender, body weight and height variables, a stepwise multiple regression analysis was used to identify the most informative variables for predicting the optimal and maximal loads during the hip adduction exercise. [Results] The regression model for optimal hip adduction load (kg) was: 34.3 + 0.4 × weight - 0.27 × height (r2= 0.77); and the regression model for maximal hip adduction load (kg) was: 39.5 + 0.5 × weight - 0.3 × height (r2= 0.75). [Conclusion] These models can aid in deciding the optimal and maximal hip adduction loads for clinical and fitness purposes, respectively. Thus, the optimal hip adduction load model can be used to strengthen the hip adductor muscles or enhance core stability in clinical settings. © 2014 The Society of Physical Therapy Science.
