KHP 350 EXAM | QUESTIONS AND ANSWERS | 2026 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
, KHP 350 EXAM | QUESTIONS AND ANSWERS | 2026 UPDATE | WITH COMPLETE SOLUTION
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
