WALKING, RUNNING, AND JUMPING

cult in only a few pages. The subject has been approached through physiology, anatomy, mechanics, and motion analysis. Noteworthy among physiologists who have studied locomotion is the British Nobel laureate, A. V. Hill (see par? ticularly, 1949). Fundamental relationships between body size and muscle dynamics have been described. Muscle performance has been related to load, temperature, and rate of contraction. The design of muscles has received attention, and further studies are in progress. Anatomical and mechanical approaches to the analysis of locomotion are usually combined, the emphasis falling sometimes to one and sometimes to the other. As long ago as 1873 a preacher named Haughton wrote a book on the principles of animal mechanics that is still superior to most texts on kinesiology. More recently, impor? tant contributions have come from Cam-
