Dance As A Performer Flashcards
Why should the body stay aligned when dancing
Effortless carriage of head Ease of movement Feeling of freedom Full body awareness Dynamic position
What influences flexibility
Age Gender Training Body temp Room temp
What exercise can you do for flexibility
Alexander technique
What concerns are there surrounding flexibility
Stretching
Joints
Name the three different joints
Cartilaginous
Fibrous
Synovial
What is the most mobile joint?
Synovial
What joint has little movement but great strength
Cartilaginous
What joint had no movement
Fibrous
5 names for the structure of a joint
Joint cavity Articular cartilage Capsule Synovial membrane Synovial fluid
What is the joint cavity
Space inside the joint
Articular cartilage - what does it do
Covers the bones, reduce friction
What does the capsule do
Surrounds the joint holding the bones and encloses the cavity
Synovial membrane what does it do
Lines the joint
What does the synovial fluid do
Fills the cavity and lubricates the joint
Flexion
Bending joint
Extension
Straightening joint
Abduction
Away from centre line
Adduction
Towards the centre line
Rotation
Around the joint axis line
Circumduction
All of the them plus motion
What is the correct posture line
Vortex of head Lobe of ear Point of the shoulder Greater trochanter at the hip joint Behind the patella In front of ankle joint
What is strength
Capacity of exert a muscle resistance against resistance
What is isometric contraction
Static resistance during which muscle tone increases but doesn’t change length
What is isotonic contraction
Dynamic resistance - muscle changes length but tone constant
What does a warm up do?
Reduce the risk of injury
Gradually prepares you mentally and physically
A warm up should include…
Pulse raiser
Mobilise the joints
Raise internal body temp
Stretch
Piles help strengthen…
Abs
Quads and hamstrings (legs)
Gracilis, adductors
Gluteus maximus (ass)
Piles help
Alignment and strength
What does moving through the feet exercise (nandos)
Warm up ankle joint and muscles in joint
Developing strength and alignment in the foot
Weight distribution
Why should you cool down
To prevent dizziness
Avoid pulls and aches
Removes waste products from muscles to prevent soreness
What is co-ordination
Transferring the direction of force in the body so that complex dance skills combinations can be performed
Two parts of the nervous system
Automatic NS
Somatic NS
What occurs in the automatic NS and the somatic NS
Automatic Functions of digestion Hormones Cardiovascular activity Somatic Movement Perceptions of movement
Two types of neurons
Motor neurones
Sensory neurones
Motor neurons…
Passes impulses from the brain to the muscle
Sensory neurons
Transmit messages
What do you get out of stretching
Overcomes blocking Safe recovery Concentration Release muscle tension Increase muscle temp Improve alignment Joint and muscle more elastic Prevent injury
Balletic method of stretching
Not recommended
Bouncing - tear muscle fibres
Static method of stretching
Long sustained stretch
Gravity increases extension
Still
Proprioceptive neuromuscular facilitation
Muscles contract whilst over relaxes
What is stamina
Endurance of either the muscle or the heart and breathing
Different types of stamina
Muscular endurance
Cardiovascular endurance
Muscular endurance
Ability of a muscle to continue to contract over a period of time
Cardiovascular endurance
Ability to continue aerobic activity over a period of time
