Describe the different types of stretching exercises used to increase flexibility, including the
advantages and disadvantages of each.
I found six different types of stretching exercises.
The first one is Ballistic stretching, this type of stretching uses the momentum of a moving body
or a limb in an attempt to force it beyond its normal range of motion. (types of stretching) one of
the disadvantages of this type of stretching would be that it does not allows the muscles to adjust
to and relax in the stretched position, therefore it can lead to an injury.
The second one is the dynamic stretching, this one involves moving parts of the body by
gradually increasing the reach, speed, and movement.

There are three factors that contribute to joint stability, these are
the shape of the articular surfaces because these are the ones that make direct contact with the
other skeletal structure.
Ligaments, because they prevent the excessive movement in a joint.
And muscle tone because this helps maintain the posture of the joints.
List and describe four different joint injuries or pathologies.
There is Dislocation which displaces the articulating bones of a joint and makes you loss the
ability to move and produce symptoms of pin and swelling (joint disorders)
There are sprains, which are the result of overstretching or tearing the connective tissues,
ligaments, and tendons associated with a joint. When someone experiences a sprain joint the
person will be limited to move and experience pain. (joint disorders)
There is bursitis which can be the result of excessive use of a joint or stress on a bursa.

(joint disorders)
And finally there is arthritis which causes inflamed, painful and swollen joints. One of the most
common from of arthritis in rheumatoid arthritis which is the most painful and debilitating for
the person who experiences it. (joint disorders)
Describe one type of PNF stretch.
One type of PNF stretch I found is the hold and relax.
In this type of PNF stretch the person puts a muscle in a stretched position and hold it for a few
seconds.
Then the person has to contract the muscle without moving by only pushing gently against the
stretch without actually moving.
The the person has to relax and stretch and then stretch again while exhaling the second stretch it
should be deeper than the first. (PNF stretching; a how to guide)

Each bone in a synovial joint has articular cartilage at the articulating surface. The C-shaped medial and lateral menisci serve to deepen the articulation at the superior surface of the tibia, thus enhancing the bony stability of the joint.
The surfaces of the joint are organised to allow only back and forth motion such as bending and straightening. This type of joint can be found between your upper arm and your lower arm, in the elbow. This type of joint is incredibly important as it allows an up and down movement, without this type of joint, we wouldn’t be able to move our arm up and down. Muscles are attached to this type of joint by tendons to allow it to contract and relax and be able to move the bone within this joint. Ligaments attach the bones in a hinge joint together, for example, the humerus and the tibia are joined by ligaments but they also have antagonist muscle pairs attached to them by tendons which allow the bone to move by contraction and relaxation of the muscles. This type of joint mainly includes long bones as it’s necessary for movement in the skeletal
Arthritis can also affect other parts of a person, such as the hearts, eyes, lungs, kidneys, and skin
Arthritis is a general term for approximately 100 diseases that produce either INFLAMMATION of connective tissues, particularly in joints, or noninflammatory degeneration of these tissues. The word means "joint inflammation," but because other structures are also affected, the diseases are often called connective tissue diseases. The terms rheumatism and rheumatic diseases are also used. Besides conditions so named, the diseases include gout, lupus erythematosus, ankylosing spondylitis, degenerative joint disease, and many others, among them the more recently identified LYME DISEASE.
Before you even start lifting weights, strength and conditioning coaches would advocate for players to do a dynamic warm ups instead of static stretches. Dynamic warm ups are series of sports specific movement preparing the body for maximum exertion of a workout allowing your joints and muscles to be limber as possible, while static stretching wants you to stretch out as far as you can and hold it for 15 seconds which is advocated at the end of each workout allowing the body to cool down. The reason why static stretching is advocated after your workout is because your muscles are already warmed up which allows your muscles and joints to stretch as far as possible without tearing. An example of a dynamic warm up and a static stretch is to take two rubber bands and stick one in the freezer; the rubber band in the freezer represents a static stretch and the other rubber band represents a dynamic warm up. When you take the rubber band out of the freezer and try to stretch it as far as possible it will break instantly because it is cold but the other rubber band which is warm would be super springy because it’s warm enough allowing you to keep stretching but return back to its normal state without tearing
Recent trends have pointed the continuing promise and growth of massage therapy as a health care career. Applied kinesiology is the scientific study of muscular movement, physical activities and the anatomy, physiology, and mechanics of the movement of body parts. Kinesiology was first created by the American/Italian chiropractor Anthony Gil in Milano, Italy. This relatively new study has many different branches of specialized studies. Many similar goals of kinesiology are to: restore normal nerve functions, have... ...
Joint fusion- when the damaged joint cannot be replaced, the joints are fused together and realigned.
Coaches talk about flexibility and its benefits every day. I knew that what I eat can influence how I perform, and how I recover. Another thing that I knew was that most health professionals are not found of much static stretching, especially without any form of a dynamic warm up. That has been frowned upon in recent years. I did learn a when reading this article as well. I was not aware of some of the injury specific training that goes on. The closest thing that I have experienced to that is rehad, but that comes after you are already injured. The numbers that specific training produces are crazy in my mind, and these types of prevention will help an enormous amount of people in the coming

Flexibility is the amount of movement your joints can move. Stretching is the key to maintaining good flexibility. As you get older, your tendons begin to shorten and tighten, restricting your flexibility. By the time you hit your mid-twenties, your bones begin to harden and your joints have already set in place. This is not bad in any way. It also means that you’re less likely to have any dislocated joints throughout your life. However, your movement becomes slower and not as smooth. You find it much more difficult to do co...
