flexibility
ability of a joint to move through its full range of motion
cartilage
cushions the ends of bones that meet in the joint
joint capsule
surrounds the joint; the inner layer secretes synovial fluid
ligaments
connect bones and joints and provides stability
active stretching
take an active role by contracting the muscles opposite to those being stretched
passive stretching
outside force assists in the stretching
ballistic stretching
uses quick jerky or bouncing movements to move joints to the end of their range of motion
dynamic stretching
controlled movement through the active range of motion of a joint
static stretching
a slow and steady stretch with a hold at the end of the range of motion
proprioceptive neuromuscular facilitation (PNF)
originally developed for rehabilitation and affects both connective tissues and nerves in order to increase flexibility
spinal cord
long thin bundle of nerves, fluid, and support cells that extends from the brain down the back
intervertebral disks
flat elastic gel filled disks that act as shock absorbers
functions of the spine
provide structural support, allows upper body to bend and twist, protects spinal cord and roots of nerves, serves as an attachment site for muscles, tendons and ligaments, supports and distributes much of body weight, absorbs impact and helps maintain bal
body mechanics
application of basic mechanical principles to the human body
posture
position of body parts in relation to one another
static posture
standing or sitting straight
dynamic posture
alignment of the body when in motion
Flexibility is most commonly defined as the ability of
a joint to move through its full range of motion
Joints such as those found in the hips and shoulders that move more freely than other joints in the body are called _____ joints
synovial
What are the structures in and around joints that connect bones and provide stability?
Ligaments
What type of stretching involves using a slow steady stretch with a hold at the end of the range of motion?
Static stretching
What type of stretching has the highest risk of injury?
Ballistic
Most fitness experts agree that you should perform stretching exercises a minimum of _____ times per week
2-3
The American College of Sports Medicine recommends that, for static stretches, each stretch be held for a duration of _______ seconds each time
15-60
What is the correct order of the five sections of the vertebrae?
