UPDATE | WITH COMPLETE SOLUTION
Biomechanics Answer - study of how forces interact to produce movement
skeletal musculature Answer - system of muscles responsible for movement
origin
insertion Answer - proximal attachment of muscle
distal attachment of muscle
agonist
antagonist
synergist Answer - prime mover; main muscle responsible for movement
muscle that slows down or stops movement
muscle that assists indirectly
first-class lever Answer - lever for which muscle force and resistive force act on
opposite sides of fulcrum (pivot point)
mechanical advantage Answer - ratio of the moment arm which applied force
acts through which resistive force acts
- greater than 1.0 person can apply less muscle mechanical advantage
,- less than 1.0 means person apply greater muscle mechanical disadvantage
second class lever Answer - resistance is between fulcrum and applied force
- mechanical advantage
third class lever Answer - muscle force and resistive force on same side
- mechanical disadvantage
patella Answer - increases mechanical advantage; maintains tendon distance
farther insertion Answer - more strength less speed
closer insertion Answer - less strength more speed
sagittal plane Answer - divides left/right (ex: running)
frontal plane Answer - divides front/back (ex side lunge)
transverse plane Answer - divides upper/lower (ex: twisting movements)
strength Answer - ability to exert force at any speed
power Answer - rate doing work (power = work/time)
work Answer - force x displacement
, acceleration Answer - change in velocity over time
powerlifting Answer - High force, but slower movements
Olympic weightlifting Answer - High power output due to explosive
movements
concentric Answer - muscle shortens (lifting phase)
eccentric Answer - muscle lengthens (lowering phase)
isometric Answer - no change in muscle length (plank)
force-velocity curve Answer - higher contraction speeds -> lower force
generation
strength to mass ratio Answer - smaller athletes have higher ratio
body mass increases more rapidly than muscle strength
gravity Answer - affects strength based on weight position
inertia Answer - resistance due to mass and acceleration
friction & fluid resistance Answer - found in machines and water based training
lower back Answer - maintain neutral spine
