flexiblity
Flexibility is defined as range of movement
(ROM). It is regarded as joint specific, meaning each joint
needs to be worked on separately. It is possible therefore to be
very flexible in your hip joint but to have very poor shoulder
flexibility.
A joint is made of bone meeting another bone
in a different connective way, whether it is through a ball and
socket joint like the hip
and shoulder, or a hinge joint like the elbow. Muscles will come
together to connect or be connected to the bones through
a tendon.
It is difficult to increase the flexibility
of tendons because they are made of collagen, which has amazing
elasticity and strength. This
is why they take a long time to heal once injured. Conversely,
a muscle will stretch and can help improve flexibility.
There are certain muscle groups that get used
a lot and accordingly hold very important roles in overall flexibility.
The opposite naturally holds true. You may notice some muscles
stretch more easily than others. This
can sometimes cause problems
as certain deeper muscle groups are over looked because either
A,
you don’t know how to stretch them or B, the stretch to
do them is quite awkward.
A Get Personal trainer will
assess your biomechanics, your goals and current joint ROM and
determine which muscle groups will
need to be stretched all the time and which others are not
so important
for you.
Many factors can play a part in your flexibility,
including, genetics, age, exercise history,
stretching and
gender. By the way, even though it appears females are more
flexible than males, no strong scientific evidence has been found
to support
this.
There are three different ways of stretching
a muscle
static
This is the most basic and common way of stretching. It involves
a very low risk level, provides moderate gains, takes up little
time, and can be done quiet easily on its own. That's why it
is always the first type of stretch that a fitness expert will
show
you. It invariably involves you taking a muscle to a mild tension
and then holding that tension for a period of between 20-60 seconds
and repeating
once or twice.
ballistic
This is more commonly seen in athletes. Ballistic stretching
involves a very high risk of injury but provides
good
gains in flexibility. It takes up little time and it can be
done on your own.
You take a muscle to a point
of tension and then repeatedly bounce on it thus opening
up and stretching
the targeted muscle/s. I must stress that this is a very advanced
technique and is only really
used by athletes who have a strong supportive biomechanical
structure capable of handling this repetitive action.
proprioceptive neuromuscular facilitation (PNF)
This can be seen with people training with partners. It has a
low level of risk of injury, and provides excellent gains
in flexibility. It does however, take up a huge amount of
time and does need to be performed with a partner.
PNF involves taking a muscle to its tension and holding for
6-10 seconds. Then, the person who is being stretched,
pushes back against the person stretching them through
the target muscle group for another 6-10 seconds.
The person being stretched
then relaxes and the stretcher then pushes further than the
first point.
This can be repeated 3-6 times until you reach a further
point than what you started with. The final stretch can then
be held for between 20 and 60 seconds.
