The aim of the study was to analyze the effect of muscle mass asym-metric between upper and lower limbs on postural stability and shock attenuation during landing. Twenty adults (without lower limb disorders and who could land from a 35-cm height) participated in this study (mean age, 21.85±2.97 years; mean height, 1.68±0.10 m; mean weight: 68.64±17.36 kg). Subjects performed one-leg landing from 36-cm verti-cal heights. Ground reaction force components and medial-lateral, an-terior-posterior, vertical and dynamic postural stability index were ob-tained from force platform recordings. We found that muscle mass in right limbs more increased than that of left limbs. Medial-lateral force, vertical force, vertical stability index, and dynamic postural stability in-dex in left leg showed higher value than that of right leg during landing. The asymmetry of muscle mass (%) and ground reaction force vari-ables showed a similar correlation, including dynamic postural stability index (r=0.316). These findings allow us to conclude that the factor of muscle mass asymmetric is a contributor to impulse control and dy-namic postural stability index asymmetry. Therefore, knowledge of bi-lateral limbs asymmetry may provide insights into exercise rehabilita-tion and performance.
