Introduction: Symmetry and asymmetry of the limbs’ movement pattern during running are introduced as one of the main critical challenges of human locomotion. The aim of this study was to investigate three planar symmetry of hip, knee and ankle joints’ moments during running at a fixed speed. Methods and Materials: the present study was conducted as a quasi-experimental study. Elite runner (age: 34.75±6.63 years) participated in this study. Running at constant speed was conducted by each subject at 2/5 m.s-1 on treadmill while kinematic (Raptor-4 motion analysis) and kinetic data (Force plate, Bertec) were captured at 150 Hz and 300 Hz, respectively. The internal joint moments in each plane were represented in the joint-coordinate system and were calculated using a standard inverse-dynamics approach and were normalized by the subject’s body mass as well as running cycle over 101 time points. Independent t tests were conducted to examine the symmetry of hip, knee and ankle moments between dominant and non-dominant joints during stance phase of running (P<0.05). Results: results of the present study showed no significant difference between two limb’s peak moments of lower joints in every three plane. Highest values of the dominant limb’s peak moments in sagittal, frontal and transvers plane were derived in (knee, ankle, hip), (hip, knee, ankle) and (knee, ankle, hip) respectively. Conclusion: Symmetry exists in lower joints three planar moments during running at the constant speed. According to the results dominant and non- dominant lower joints play propulsive and absorbent roles cooperatively.
