Biomechanics Exam
Aristotle - Answer-First to analyze the movement of body
was interested in the way things fell
first analysis of gait
Archimedes - Answer-mathematician, determined the centre of gravity of body segments using floating
bodies
Leonardo Da Vinci - Answer-anatomy as a science, related balance and center of gravity
first to study locomotion, posture and daily actions, made very accurate drawings
Galileo Galilei - Answer-acceleration, inertia, trajectory, projectiles, balance and levers
disproved Aritotle's falling theory, (gravity)
Giovanni A.Borelli - Answer-concept of body levers in segments
muscular contraction, father of modern kinesiology
Isaac Newton - Answer-3 laws, inertia, acceleration and action-reaction
, law of gravity
Marey - Answer-first to use images to evaluate movement, took series of images and put them beside
each other to describe movement, developed fast snapping camera, first qualitative analysis, force
plates
Muybridge - Answer-first to use cinemetography, used video to analyze movement, would look at how
people move
Modern Biomechanics - Answer-relies on non-invasive techniques, relies on knowledge of
biomechanical body constants (CofM, gravity, length, mass)
Movement Analysis System - Answer-video cameras, vicon system: little balls are placed on the body,
the light is shined on the balls and movement is analyzed based of the reflection of the light off the balls
at the joint (space over time)
Dynamic Analysis - Answer-platform strength, ergometer, use force plates to measure force being
applied and kinetic force, what direction the force is being moved in
- Isokinetic Ergometer: has a motorized machine, lever, and then attach a leg to it, and can measure how
much force is being used in that movement, measure strength at certain angles of force, (not as popular
because it is unnatural movement)
EMG - Answer-usually with surface electrodes, will send signal from which muscles are being used, and
when they respond
Sports and Biomechanics - Answer-analyze human movement and how the top athletes do their skill
Goals of biomechanics and researchers - Answer-Hoshizaki: looks at head injuries
Lamontague: occupational biomechanics
