In this section you will learn the basic definitions of stretching and joints.
What is stretching?
What is stretching?
Stretching is a physical exercise that requires putting a body part in a certain position that'll serve in the lengthening and elongation of the muscle or muscle group and thus enhance its flexibility and elasticity.
For example: To stretch your quadriceps (front muscles of your thigh) you need to pull your leg to the back.
Watch the following video to learn more about the definition of stretching.

What is a joint?
What is a joint?
A joint is a structure in the body where two or more bones meet in the body held in place by connective tissues such as ligaments and tendons.
Joints allow our bodies to move in different ways, such as bending and twisting, and they help us to maintain our balance and stability.

What are the parts of a joint?
What are the parts of a joint?
A joint is a complex structure that comprises several different parts, each with its unique function.
Bones: basic building blocks of the joint that form the joint's s articulating surfaces.
Tendons: connect the muscles to the bone, allowing for the muscle's contraction and movement of the joint.
Cartilage: smooth, elastic tissue that covers the ends of bones, providing cushioning and shock absorption.
Synovial Capsule: connective tissue that encloses the joint, containing synovial fluid, which lubricates and nourishes the joint.
Ligaments: tough, fibrous bands of tissue that connect bones to each other, providing stability and limiting excessive movement of the joint.

How do joints work?
How do joints work?
When muscles contract, they pull on the tendons, causing the bones to move at the joint.
The movement of the bones at the joint is facilitated by synovial fluid, which lubricates the joint and reduces friction between the bones.

Why do I need to learn how to stretch properly?
Why do I need to learn how to stretch properly?
Learning how to stretch properly is crucial for preventing muscle strain and joint sprain, which can be painful and limit mobility.
If muscles are not properly prepared and warmed up before exercise, they are more susceptible to injury.
Similarly, if joints are not properly stretched and lubricated, they may become stiff and less flexible, leading to an increased risk of joint sprain or strain.
Improper stretching can also lead to imbalances in muscle development and postural alignment, further increasing the risk of injury.
By learning how to stretch properly, you can reduce the risk of injury, improve flexibility and mobility, and enhance overall physical performance.
Muscle Strain
Muscle Strain
Stretching incorrectly can cause muscle strain by putting too much stress on the muscle fibers, causing them to tear or pull.
This can happen if :
The stretch is held for too long.
The muscle is not properly warmed up.
The stretch is performed too aggressively.
When the muscle fibers tear or pull, it can cause pain, swelling, and limited mobility.
It's important to stretch slowly and gently, gradually increasing the intensity and duration of the stretch over time.
Proper warm-up before stretching can also help to reduce the risk of muscle strain by increasing blood flow to the muscles and preparing them for the stretch.

Joint Sprain
Joint Sprain
When the ligaments are stretched beyond their normal range of motion, it can cause them to tear or become damaged, resulting in pain, swelling, and limited mobility.
In severe cases, it can even lead to joint dislocation or other serious injuries.
To prevent joint sprain, it's important to stretch properly:
With proper form and support.
Gradually increase the intensity and duration of the stretch over time.
Avoid stretching beyond your normal range of motion.
Listen to your body's signals (pain) to prevent injury.
