test: flexibility Flashcards
define: flexibility
the range of motion around a joint or series of joints
what are the two types of flexibility?
static flexibility and dynamic flexibility
define: static flexibility
the range of motion around a joint in a still position
what are the two types of static flexibility?
- static active flexibility
- static passive flexibility
define: static active flexibility
when the performer themselves moves a joint to the point of resistance
using the agonist muscle, without any other assistance
define: static passive flexibility
when the joint is moved to the point of resistance with assistance
define: dynamic flexibility
the range of motion around a joint moving or at speed
what are the 4 main factors that affect flexibility?
- type of joint
- length of surrounding connective tissue
- gender
- age
how does the type of joint affect flexibility?
the joint type determines the number of planes that a joint can move in
and therefore the range of motion/flexibility
e.g. ball and socket joints (3 planes) have a greater range of motion than hinge joints (1 plane)
how does length of surrounding tissue affect flexibility?
the longer the length and elasticity of the surrounding tissue,
such as ligaments, tendons and muscles,
the greater the range of flexibility
how does gender affect flexibility?
females tend to have greater flexibility than males
due to higher levels of the hormones oestrogen and relaxin.
these hormones increase connective tissue elasticity
how does age affect flexibility?
flexibility is greatest in childhood and declines with age
as elasticity in the surrounding connective tissue is lost
what other factors affect flexibility?
- joint
- shape
- muscle elasticity
- age
- gender
- temperature
- muscle size
what are the two ways of evaluating flexibility?
- sit and reach test
- goniometry
what are advantages of the sit and reach test?
- equipment is relatively cheap
- the test is easy to administer
- standardised tables are available for comparing test results
