The biomechanical advantage of lordosis and hip extension for upright activity. Man as compared with other anthropoids.
The mechanics of the muscle-ligament system for a weight lift in man is described. The adaptations of the human spine and the hip to this mechanism are indicated. The efficiency of this mechanism in the human is compared with other primates showing the vast superiority of man in this aspect over his nearest relatives.
