Abstract: A plethora of research has examined bilateral and reciprocal concentric strength relationships of the thigh musculature in a variety of athletic populations. However, little research has reported strength values of the trunk and hip musculature. Thus, the purpose of this investigation was to examine concentric and eccentric strength of the trunk and hip flexor and extensor muscle groups in female runners. Twenty-one habitual female runners were assessed for trunk and hip strength via isokinetic dynamometry (KinCom, Chattecx Corp.). Strength was reported in newtons (N) and calculated as the average force over the range of motion in which the joint was tested. Eccentric strength at the trunk was greater than concentric strength. Similar results were found at the hip. Reciprocal muscle group ratios revealed that concentric trunk flexion was 52% of extension. Eccentric trunk flexion was 39% of extension. Concentric hip flexion was 98% of extension. Eccentric hip flexion was 103% of extension. The ratios were not significantly different. These findings establish previously unreported isokinetic strength values for the trunk and hip in female runners.
