Elements of Stretching

There are three factors to consider when determining the effectiveness of a particular stretching exercise:

Isolation
Leverage
Risk

Isolation:

A particular stretch should work only the muscles that are being stretched. Isolating the muscles worked by a given stretch means that there's no worry about having to overcome the resistance offered by more than one group of muscles.

Leverage:

Having leverage during a stretch means having sufficient control over how intense the stretch becomes, and how fast. If there is good leverage, a person can not only achieve the desired intensity of the stretch but also does not need to apply as much force to the outstretched limb in order to effectively increase the intensity of the stretch. This gives greater control.

Risk:

A stretch may be very effective in terms of providing a person with ample leverage and isolation, the potential risk of injury from performing the stretch must be taken into consideration. Even an exercise offering great leverage and great isolation may still be a poor choice to perform. Some exercises can simply cause too much stress to the joint (which may result in injury). They may involve rotations that strain tendons or ligaments or put pressure on the disks of the back or contain some other twist or turn that may cause injury to seemingly unrelated part of the body.

Digestive System

The digestive system is made up of the digestive tract- a series of hollow organs joined in a long, twisting tube from the mouth to the anus and other organs that help the body break down and absorb food. Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine also called the colon-rectum and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract. Two "solid" digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts. The gallbladder stores the liver's digestive juices until they are needed in the intestine. Parts of the nervous and circulatory systems also play major roles in the digestive system.

PNF Stretching

PNF is an acronym for Proprioceptive Neuromuscular Facilitation . PNF is not really a type of stretching but is a technique of combining passive stretching and isometric stretching in order to achieve maximum flexibility. PNF was originally developed by a physical therapist as a method of rehabilitating stroke victims. PNF consists of a muscle being passively stretched, then contracted isometrically against resistance while in the stretched position and then being passively stretched again through the resulting increased range of motion. PNF usually employs the use of a partner to provide resistance against the isometric contraction and to then take the muscles through its increased range of motion.

What is Anatomy?

WHAT IS ANATOMY? Anatomy is the branch of biology, concerned with the study of the structure of living organisms and their parts. It is the structural study of the organism including their systems, organs, and tissues. In simples words, anatomy is the GPS of our body. This picture represents the STANDARD ANATOMICAL POSITION which one must remember in order to learn about anatomy. source: google WHAT IS STANDARD ANATOMICAL POSITION? Standard anatomical position is what will help us to have reference points. We need to know that standard anatomical position because the human body is dynamic and keeps changing position. Anatomical position is like a body-map, it is the reference position where: Body is standing upright feet shoulder width apart and parallel Toes forward Arms to the sides Palms facing forward face in the front Eyes are wide open This is the starting position for all muscle actions. The body is standing upright with the arms at t...
