Abstract

Background and purpose. Many studies have been done to look at sport specific muscle development for a variety of sports such as football, baseball, hockey, and soccer. However, there has been little to no research geared towards equestrian athletes. This study was designed to provide a baseline of hip adductor and abductor muscle strength for English hunter/jumper riders and Western riders, as well as to compare the adductor: abductor strength ratio of these different styles of riders to each other and to a non-rider control group.

Methods. Sixty subjects were divided into three groups including English hunter/jumper riders (E-R), Western riders (W-R), and nonriders (N-R) acting as the control group. Hip adductor and abductor strength was measured for each leg using a stabilized hand-held dynamometer. Body weight was also collected. Comparisons were made between the adductors and abductors of each group as well as the ratio of adductors to abductors.

Results. There was a significant increase (p < 0.05) in the left hip adductor muscles as a percentage of body weight in both rider groups. A significant increase in add:abd ratio also occurred in both rider groups compared to the non-riders.

Conclusion and Discussion. A greater increase in hip adductor strength and add:abd ratio occurs in both English and Western riders on the left lower extremity more than the right. This difference in one leg versus the other can be
