Biomechanics Exam 1 Study Guide
Biomechanics - Answer-the physics (mechanics) of motion produced by biological systems; (more
specifically) an integrated field of study that examines the forces acting upon, within, and produced by a
body.
Kinematics (give an example of how this perspective might be used) - Answer-study of the *spatial &
temporal* characteristics of motion W/OUT regard to the causative force.
@ space & time: displacement, velocity
Kinetics (give an example of how this perspective might be used) - Answer-study of *forces* that
inhibit, cause, facilitate, or modify motion of body.
@ forces: gravity, friction
Improvement in technique, equipment, and training, & prevent - Answer-4 general ways can
biomechanical knowledge lead to improvements in performance?
Qualitative analyses (how different from quant.; when and why one would use it) - Answer-based on
direct observation;
Fancy equipment NOT always necessary;
Focus on time and space;
Kinematic
, @ teachers/coaches notice a skill performed incorrectly and provide feedback.
Quantitative analyses (how different from qualit.; when and why one would use it) - Answer-based on
data collected;
Numerical;
Equipment Necessary;
focus on forces;
kinetic;
@ S shaped stroke (researchers in the '70s foudn that lift forces improved propulsion vs. pulling hand
straight back.)
efficiency & safety equipment improvements (resulting in improvements in performance and reductions
in injuries) - Answer-Equipment with *safety improvements*
@ Mountaineers: clothes changed to down coats, suits, boots; prevent hypothermia
Equipment with *efficiency improvements*
@ Mountain bikes: rigid to suspension; absorbs shock
@ bathing suits: shark suits make swimmers faster
Equipment serving Both:
@ tennis shoe : too stiff (not efficient) -> too soft/unstable (rolled ankle) -> stability and cushioning
(efficient and injury prevention)
trial-and-error (examples of how it has led to improvements in a particular skill.) - Answer-(example)
@ High jump: "the fosby flop"; going over backward allows higher "center of gravity"
@ Cross country vs. skate skiing: diagonal is more efficient & faster than parallel
