Dance knowledge Flashcards
Alignment
The relationship of the skeleton to the line of gravity and base of support
Aural setting
The sounds that accompany the dance. Music, found sounds, natural sounds & voice
Balance
A state of equilibrium referring to the balance of weight
6 basic actions
Elevation, traveling, stillness, gesture, turning and falling
Fragmentation
To use only part of a motif to isolate movements
Principles of safe dance
Alignment, strength & stamina, flexibility, co-ordination & technical skill and general body maintenance
The correct alignment runs through what?
The ear lobe, shoulder, hip joint, behind the patella, in front of the ankle joint
Which muscles are responsible for maintaining an up right posture?
The anti-gravity postural muscles
Which two muscles work together to balance the body?
The anterior and posterior muscles
What do the anterior and posterior muscles do
Extend and contract to balance the body
What does the spine do?
Protects the spinal nerve chord, supports the head, ribs and hips, maintains an upright posture and absorbs shock
How many curves does the spine have and what do they do?
- They speed stress
What absorbed shock when landing from jumps
The cartilaginous spongy discs between the vertebrae
What are the three main sections in the foot?
The tarsus, the metatarsus and the phalanges (toes)
Possible issues with the spine
The extensor muscles can give an over extended back and the flexor muscles can give a curved spine
What’s plantar flexion?
Pointing the feet
What’s dorsi flexion?
Flexing the foot
What is the strongest joint?
The hip
Why is the hip the strongest joint?
Because of its heavy net of ligaments
What are the problems with having tight muscles around the hip?
It can create misalignment and forces turn out
What type of joint is the hip joint?
A ball and socket joint. It gives great stability but also a large about of movement
What to do when injured?
PRICED Prevent further injury Rest Ice Compress Elevate Diagnosis
What is warm up?
A warm up is a gradual physical and mental preparation for greater exercise later
What does a warm up do?
Increase breathing and heart rate Increases temp. in muscles Increases flexibility Increases reaction speed Increases blood sugar and adrenaline levels
What is a cool down?
A cool down is a gradual slowing down of the circulation in order to return safely to a resting heart rate
What does a cool down do?
Promotes blood circulation to remove waste products like toxins
Prevents soreness in muscles
And prevents pooling of blood
What is flexibility?
Flexibility is the freedom to move. Flexibility involves increasing muscular elasticity so that a large range of motion may be reachable
What are the limits to flexibility?
Tight ligaments, tendons or bone restriction.
What is flexibility effected by?
Age, gender, room temperature, training and body type
What do more flexible bodies do?
Avoids misalignment, muscle tears and general injury
What are the two areas that effect flexibility?
Joints and stretching
What are the three types of joints?
Cartilaginous joints
Fibrous joints
Synovial joints
What are cartilaginous joints?
They are joints that allow little movement but offer great strength. The cartilage, containing water, acts as a cushion between bones. For example the spinal vertebrae
What are fibrous joints?
These joints allow little to no movement. For example the flat bones in the skull
What are synovial joints?
These joints are the most mobile. So in dance these joints offer most concern. For example the hips, the shoulders, the figures, the toes, the knees and the ankles
What do joints range from?
Flexion, extension, addiction, abduction, rotation and circumduction
What is strength?
Strength is the capacity to exert a muscle contraction against resistance.
What does strength do?
Strength reduces risk of injury
Improves flexibility
Improves co-ordination & performance
Enhances the toned ‘look’ to the body
What are the two types of muscle contractions?
Isotonic and isometric contractions
What is an isotonic contraction?
An isotonic contractions is a dynamic contraction where the length of the muscle is changed but the tone remains constant. E.g batment tondu. Kicking the leg to the side
What is an isometric contraction?
An isometric contraction is a static contraction where the length of the muscle remains the same but the tone increases. For example holding the leg up to the side
