Shoulder  Tendonitis

Shoulder tendonitis is considered to be an inflammation of the biceps tendon and / or rotator cuff muscles. It is usually evident because of impingement of surrounding structures on the tendon through pattern overload.

Specificity

Adaptation produced will be specific to the nature of the stimulus.

Spondylolisthesis

Due to a fracture at the pars interarticularis there is a anterior shear displacement of a superior vertebrae. This usually occurs at L4 or L5.

Stabilisation

Stabilization is important throughout the entire body. Ranging from the core to core muscles of our body such as the Transverse abdominus (TVA) to muscles that assist in stabilizing other joints such as the shoulder. To stabilise a joint means to hold in its correct position and allow it to perform it functional role without undue stress or incorrect movement patterns in particular areas causing an intrinsic dysfunction leading to pain and injury. The inability to stabilise the scapula is a common cause of problems surrounding the shoulder. Stabilise the shoulder in general assists in maintaining correct alignment or ideal posture and assists in efficient execution of movement.  

Stabilizers

Muscles that surround the joint or body part and contract to fixate or stabilize the area to enable another limb or body segment to exert force and move; known as fixators, they are essential in establishing a relatively firm base for the more distal joints to work from when carrying out movements.
 

Static Stretching

Slow movement places the muscles on stretch, then held for 5 to 60 seconds at the end of the range. There is no bouncing or jerking action in the movement.

Starch

Starch is the major storage form of carbohydrate in plants. It is composed of long chains of glucose molecules in a straight (amylose) or branching (amylopectin) arrangement.

Stretch Reflex

This is a protective mechanism for the muscle. When stretching a muscle proprioceptors called muscle spindles have a big influence over the stretch taking place. Muscle spindles lie parallel to the fibres and record the change in length of a muscle fibre. This information is sent to the CNS which triggers the stretch reflex. The stretch reflex tries to resist the change in muscle length by causing the stretched muscle to contract. This is a protective mechanism designed to protect the body from injury.
The stretch reflex consists of 2 components
    1) Dynamic component
        The dynamic component of the stretch reflex is momentary and is response to the initial
        changing of muscle length.
    2) Static component
        The static component continues as the muscle is held in a stretched position.

Sprain

Is an injury associated with ligaments caused by excessive or sudden overstretching. The ligament can be stretched, slightly torn or completely ruptured. Strains are graded similar to strains in degrees 1 to 3, 1 being the least severe.     
 

Strain

Associated with muscles and can apply to the muscle itself or attaching tendon. Muscle damage can be in the form of partial tears or full tears. A muscle strain can also damage small blood vessels, causing local bleeding (bruising) and pain (caused by irritation of the nerve endings in the area). 

Supination 

This can be used to describe movement of the hand and foot. At the hand it describes the movement - rotation of the palm upwards and outwards. Rotation of the foot which directs the sole inwards or towards the other foot.

Synergist

Muscles that assist in the action of the agonists but are not primarily responsible for the action; known as guiding muscles, they assist in refined movement and rule out undesired motions.
 

T

Tachycardia

An increased or rapid resting heart rate or pulse.
 

Thermogenesis      The creation of heat.
Thermoreceptors

These are sensory receptors that detect changes in tempertaure.

Target Heart Rate

Prescribed heart rate figure for a training session designed to achieve a physiological outcome.          

Tendon

A band of connective tissue (predominantly collagen, type I) that connects muscle to bone.
Trace minerals

Minerals occur in tiny amounts or traces. They play a major role in health, since even minute portions / amounts of them can powerfully affect your health. They are essential in the assimilation and utilization of vitamins and other nutrients. They can aid in digestion, provide the catalyst for many hormones, enzymes and essential body functions and reactions and also aid in replacing electrolytes lost through intense exercise and heavy perspiration.

U

Unilateral

Affecting one side. 
 

Upper Cross Syndrome

Similar to the muscle imbalance called kyphosis where there is a muscle imbalance of the upper body. Consists of tight anterior muscles such as the pectorals, anterior deltoid, rectus abdominus, and posterior the muscle – latissimus dorsi. Weak posterior muscles include scapula-thoracic muscles such as lower trapezius and rhomboids to name a few.

V

Valsalva Maneuver

This technique is commonly employed during strength training (among weight lifters specifically)and involves forceful exhalation while holding the mouth and nose closed designed to increase thoracic pressure. This maneuver can have dangerous implications. From a clinical standpoint it is used to test autonomic reflex control of cardiovascular function. 
 

Venous Pooling

This is the retention of blood in the venous system and can lead to dizziness and fainting. It occurs due to lack of sympathetic activity and loss of active muscle function in the lower extremities and trunk musculature.

Venous Return

The flow of blood back to the heart from the venous system.

Venous System

Is the system of vein responsible for blood flow back to the heart.
There are three divisions of the veins in the lower limbs
1. Superficial - veins that run close to the surface,
2. Deep - run within deep compartments and muscles,
3. Communicating (also called perforating) Veins - connect the superficial to the deep veins

Viscosity

Refers to a fluids (i.e. blood) resistance to flow under force. Greater viscosity refers to a greater resistance to flow.

Vertebrae

These are the individual bones that comprise the sections of the spinal column.
 

VMO

Correctly labeled the Vastus Medialis Obliquis. It is a division on the quadriceps muscle. Situated anterior and medial to the knee.

Volume                       

This refers to the total amount of work completed in a session or designated time frame and can be expressed in many ways such as km run in a session or week or evenly simply reps, sets and load (kg) lifted. 

W

Watt                                 

A measurement used to describe power output.
 

White Adipose Tissue  

Specialised connective tissue that serves 3 primary functions. It acts as a heat insulator, mechanical cushion and a source of energy for the body mechanisms.

X

There are no "X" listed.

Y

Yoga                 

 Freedom of the self from its temporary state through methods such as exercise and relaxation.

Z

Zygomatic Bone       

More commonly known as the upper cheek bone.
