The purpose of this study was to quantify changes in postural stability with fatigue of the frontal and sagittal movers of the lower extremities. There were four test sessions, with a randomized order assigned according to the muscles tested and the plane of motion. Subjects were 20 healthy men (age: 22.6 ± ۲٫۴ years, height: 173.7 ± ۳٫۶ cm, weight: 63.3 ± ۷٫۹ kg). During each session, one set of muscle groups was fatigued using isokinetic contractions: ankle plantar/dorsi flexors, ankle evertor/invertors, hip flexor/extensors or hip abductor/adductors.
