ABSTRACT
This chapter describes the major biomechanical characteristics. It explains the different motor skills related to different types of technical executions and the different kinematic chains and their actions. The chapter also explains the different leverages used for different techniques and their mechanical advantage, if any. It also describes center of gravity and base of support of the judoka in static and in dynamic position. The chapter examines the major take-down technical characteristics. Talking about take-down, it is obvious that any kind of throwing similar to the judo technique represents a take-down, which is used in jujutsu or sambo. Judo throwing or takedown is executed mostly with a motion that requires total body coordination and the most important is the arms/hands guiding movements. The chapter explores the role of the major neck muscles in the position of the bridge and the role of the neck extensor and flexor muscles.
