Dancer In Action

The Dancer;

• Tight but moveable (eg. cotton) clothes should be worn. This is so that the lines the dancer makes can be see but also so that the dancer is in no way restricted by their clothes
• Hair should be tied back so that it does not detrect from the performance of the dancer
• bare feet or jazz shoes should be woren
• no jewellery should be worn

The Studio;

• The temperature of the studio should be at 21 degrees
• The floor should be sprung to prevent the dancers from injuring themselfs when landing jumps ect.
• There should be no objects in the way, or sharp ones on the floor
• No spillages on the floor
• Only bottled water should be taken into the studio
• There should be no lose wires around the sterios
• No power shocked should be left switched on

The Session;

• There should always be a warm up; this is because -
• it increases the dnacers heart rate
• it increases the blood flow to the working muscles
• it makes the muscles more elastic
• it get the dancers into the right frame of mind for dance
• it can get the dancers motivated
• There should also be a cool down; this is because -
• it prevents blood pooling in the legs
• it decreases heart rate back down to resting
• allow the body to get rid of waste products such as latic acid
• gets the dancer back into the right frame of mind for everyday life

The Bones;

• Head; Cranium
• Arms; Scapula, Clavicle, Humerous, Ulna, Radius
• Hands; Carples, Metacarples, Phalangies
• Spine; Cervical vertebrate, Thoratic vertebrate, Lumbar vertebrate
• Torso; Sternum, Ribs, Pelvis
• Legs; Femur, tibia, fibula
• Feet; tarsels, metatarsels, phalangies

Bone groups - Long Bones; produce the red blood cells!

Shorts Bones; weight bearing bones, needed for balance!

Flat bones; protect vital organs!

Irregular bones; create shape & protect!

Five functions of the skeleton is to protect, support, create movement, create shape, and blood production.

Muscles;

• Head; Frontalis
• Arms; Triceps & Biceps
• Torso; pecs, abdominals,
• Back; trapzious, detoils, latissamus dorsi
• Legs; Gluets, Quadriceps, gastrinimious

Muscles need a constant supply of oxygen to work.

Strecthing;

Active; This is when the stretch held is isometric.

Passive; This is when the muscle is being strecthed by a partner or a resistance.

PNF: Is the quickest and most effective method of increasing flexablitiy. It is when The strecth is held against a resistance, then released and then pushed further. 

The Respiratory system; This is the cardio-vascula system but it includes the lungs.The cario-vascula system; This is made up of the heart, the veins, the arteries and the capillaries.The blood; 5% plasma, 20% haemyoglobin, 75% hydrogen carbonate

The muscles need oxygens as energy. When oxygen is transported to the working muscles it diffuses into the muscles and latic acid and carbon dioxide (waste products) are taken away.

Movements! Adductions - Movements towards the body

Abduction - Movements away from the body

Rotation - Turning

Extention - Straightening of the joint

Flexion  - bending at the joint

Circumduction - Full circle

A balanced diet is including sufficent amounts of food from each of the seven classes of food in moderation.

• Carbohydrates; Energy source
• Proteins; Muscle repair
• Fiber; Aids digestion
• Minerals; eg. calcium, strengthens bones
• Vitamins; Aid digestions, helps break down amino acids 
• Fats; Secondary energy source 
• Water; Hydration
