NASM- Functional Biomechanics

Question 1

biomechanics

Answer 1

science concerned with internal and external forces acting on the body

Question 2

force

Answer 2

influence applied by one object to another, accelerates or decelerates the second object

Question 3

Torque

Answer 3

A force that produces rotation

**The closer the load to the point of rotation the less torque it creates ( i.e bent arm is easier than straight arm)

Question 4

Lever

Answer 4

rigid “bar” that rotates around a stationary fulcrum

Question 5

1st Class Lever

Answer 5

fulcrum in the middle ( nodding head)

Effort and resistance on either side

Question 6

2nd Class lever

Answer 6

resistance is in the middle (calf raise)

effort and fulcrum on wither side

Question 7

3rd Class Lever

Answer 7

effort in the middle (biceps curl) most common in human limbs .

Question 8

superior

Answer 8

above point of referance

Question 9

inferior

Answer 9

below point of reference

Question 10

Proximal

Answer 10

nearest to a point of reference

Question 11

Distal

Answer 11

farthest from a point of reference

Question 12

Anterior

Answer 12

front of the body

Question 13

Posterior

Answer 13

back of the body

Question 14

Medial

Answer 14

closer to the middle of the body

Question 15

Answer 15

farther from the middle of the body

Question 16

Contralateral

Answer 16

on the opposite side of the body

Question 17
