Human Movement Science- HMS

Question 1

stretch-shortening cycle

Answer 1

a loaded eccentric contraction that prepares muscles and tendons for a rapid concentric contraction. The eccentric contraction represents the “stretch” component, which stores elastic energy from the springlike nature of contractile tissue.

Question 2

Which muscle groups work both eccentrically and concentrically in the sagittal plane during a squat?

Answer 2

Quadiricep

Question 3

concentric muscle action.

Answer 3

The development of muscle tension during shortening of the contractile tissue

Question 4

third-class lever

Answer 4

has the effort arm between the resistance arm and fulcrum; thus, the biceps curl is a classic example, as the fulcrum is at the elbow joint, the effort is the tendon attachment at the forearm, and the resistance arm is the load at the hand

Question 5

Synergist function

Answer 5

muscles that work to assist a primary mover in achieving the primary movement of interest

Question 6

Contralateral

Answer 6

something that is positioned on the opposite side of the body.

Question 7

The collective components and structures that represent the human movement system (HMS)

Answer 7

Muscular, nervous, and skeletal

Question 8

What is part of the posterior oblique subsystem

Answer 8

Thoracolumbar fascia and contralateral gluteus maximus

Question 9

isotonic contraction

Answer 9

A contraction that occurs when muscle tension is developed and movement occurs through a given range of motion at a speed that may vary
