The indirect measurement of biomechanical forces in the moving human body

摘要: Inexpensive experimental techniques now exist for indirectly measuring forces within the moving human body. These involve nontrivial applications of basic physical principles, have practical uses, and are appropriate undergraduate experimentation. A two-dimensional video motion analysis is used to find accelerations various parts body, anatomical geometry determine specific biomechanical torques. The simple movement a dancer landing from vertical jump analyzed through use theoretical model leg in tendons attached knee. It shown that these can be sufficiently large lead injury if jumps performed repetitively.
