Intro to biomechanics Flashcards
biomechanics
study of forces and their effect on living things
3 parts of mechanics
statics, dynamics, fluids
statics
no change in motion
fluids
gasses and liquids
dynamics
experiences a change in motion
what type of mechanics is blood in the heart an example of
fluids
kinematics
how things move
kinetics
why things move
energy
capacity to do work
work
change in energy
power
rate that work is performed
2 types of mechanical movement
kinetic and potential energy
what type of mechanical energy is gravity
potential
chemical energy
energy stored in chemical bonds
what makes muscle a special case
contractility
contractility
ability to contract and product force
what 5 things affect a muscles ability to produce force
motor unit recruitment, firing rate, muscle architecture, length-tension relationship, force-velocity relationship
