Chapter 8 Flashcards
What are the six steps to any resistance exercise?
What is the motion to be performed?
- Determine the direction of resistance
- Determine the starting position
- Monitor joint position/stabilization
- Monitor the path of motion
- Determine and monitor the range of motion
What are the three types of range of motion?
passive, active, resisted
What is active range of motion?
Your muscular ability to move
What are the five sections that make up the vertebral column?
cervical (7), thoracic (12), lumbar (5), sacrum (5 fused), coccyx (3-5 fused)
How many vertebrae make up the vertebral column?
33
What are the four spinal motions?
Flexion, extension, lateral flexion, rotation
What is the number one cause of back pain?
long periods out of a neutral spine
How much does the intradiscal pressure increase when someone goes from a standing position to a seated position?
30-40%
(T/F)? when training the rectus abdominis you can’t create regional emphasis on upper or lower abs.
False; you can create regional emphasis because of segmental nerve innervation.
What muscles play a role in stabilizing the trunk?
Back extensors, lateral flexors, anterior abdominals
What should you look for when assessing someone’s posture?
know your limitations, know when to refer, minimize clothing, analyze “natural” posture
When beginning a strength program what should precede mobility?
Stability before mobility
What is the law of facilitation?
When an impulse passes once through a given set of neurons to the exclusion of others it will tend to do so on future occasion and each time it travels this path the resistance will be smaller.
What is the goal of the seated posture trainer exercise?
To teach proper body alignment and increase postural control and strength.
What is abdominal coordination?
The ability to stabilize the pelvis and lumbar curvature while simultaneously raising and lowering the leg (s).
