The document defines flexibility as the range of movement available at a joint. It discusses the importance of flexibility for improving posture, reducing injury risk, and maintaining a healthy spine. There are three main types of flexibility: dynamic, static-active, and static-passive. When stretching, the body uses a stretch reflex to prevent overstretching and muscle tears. There are two main types of static stretching: passive, using an external force, and active, using opposing muscles. Stretching should only be done after exercise when muscles are warm to avoid injury. Both strength and flexibility training are important.

1. What is flexibility?
Flexibility can be defined as:
“A range of movement available at a joint”.
Why do it?
To improve physical fitness
Effective flexibility will:
-Improves posture
-Reduces the risk of injury
-Maintains a healthy spine
-Reduces the risk of back problems

2. Types of flexibility
• dynamic flexibility
– Dynamic flexibility (also called kinetic flexibility) is the ability to
perform dynamic (or kinetic) movements of the muscles to bring a
limb through its full range of motion in the joints.
• static-active flexibility
– Static-active flexibility (also called active flexibility) is the ability to
assume and maintain extended positions using only the tension of
the agonists and synergists while the antagonists are being
stretched.
• static-passive flexibility
– Static-passive flexibility (also called passive flexibility) is the ability
to assume extended positions and then maintain them using only
your weight, the support of your limbs, or some other apparatus.

3. What happens when we stretght ?
-The body prevents over stretching and tearing of muscles by using a
stretch reflex
-When the body thinks that the muscle is about to overstretch it causes
a big contraction that immediately stops the movement and prevents
damage

5. Types of stretgh
Static stretching
-when stretches are performed with no movement
Static stretching-passive
-Passive- An external force holds and creates the stretch
Static stretching-active
-Active- This is when the opposing muscle holds the stretch in place

6. When do we stretch?
Stretching must only be preformed after
exercise when the muscles are warm and
pliable
Stretching cold muscles can result in tearing
and damage
Flexibility requieres that you are both warm
and relaxed

7. Conclusion
• Strength training and flexibility training should go hand in hand. It is
a common misconception that there must always be a trade-off
between flexibility and strength.
