The influence of a regular exercise program of isometric contractions of the thigh adductor muscles upon the range of passive thigh abduction and the maximum isometric strength of the adductors was examined. A sample of 52 female college students divided in four groups were trained during 2 weeks under conditions which combined two dependent variables: (1) degree of thigh abduction, and (2) percentage of maximum isometric force developed for each contraction during the program. No change in the angle of passive thigh abduction was found after training. On the other hand, a significant increase in maximum isometric strength occurred. It was noted that under conditions of maximal work (100% of isometric strength), the anatomical position was the most effective in increasing strength of the adductor muscles. The findings indicated that a program increasing the maximum isometric strength of the adductor muscles did not improve the range of passive thigh abduction during a ten day period. On the other hand, within a two-week training period, the development of strength did not restrict the flexibility at the hip joint. / Simultaneously, an objective method for the measurement of passive thigh abduction was tested; it was designed to maximize the reproducibility of the testing positions, the torque responsible for the passive movement and the level of muscular tension. / It was found that under condition of muscular relaxation controlled by electromyography, the reliability coefficient for the measurement of passive thigh abduction reaches .94. / Source: Dissertation Abstracts International, Volume: 41-02, Section: A, page: 0587. / Thesis (Ph.D.)--The Florida State University, 1980.
