| Research Abstract |
Bipedalism, being substantially related to the human land locomotion, involves several critical disadvantages, such as back pain, hemorrhoids, dizziness when standing up, and relatively lower maximal running speed. In spite of those biological disadvantages, bipedal locomotion takes some advantages such as higher locomotion economy that can save energy expenditure and relatively larger head volume that results in an intellectual growth as human beings. Leg extremities for executing bipedal locomotion involve several sets of synergists. From a biological viewpoint, the existence of synergist in the leg extremities seems to be a biological vain, but it may play a compensatory role in a case that a part of synergetic muscle is fatigued. The present study examined muscle activities of the synergists in the leg extremities during human locomotion and dynamic/static knee extension exercises for examining its physiological polymorphism and functional potentiality.
