Safe dance principles, alignment and posture
Transcript of Safe dance principles, alignment and posture
The term 'lordosis' can be used to refer to the normal lordotic curves (cervical and lumbar). The term is also very often used to describe abnormal curvature in any area of the spine in which the bones go forward (when viewing from the side). In lumbar and cervical abnormal lordosis, the normal curves are exaggerated. Although this doesn't happen very often, the term lordosis would describe a reversal of the curve in the thoracic area of the spine. A variety of conditions can cause lumbar lordosis such as obesity, kyphosis, spondylolisthesis, or discitic. The condition is sometimes referred to as “swayback,” “saddleback,” or “hollowback.”
Safe dance principles, alignment and posture
The Pull of gravity is the primary reason why alignment is so important for safe dance practice. Alignment is most often defined in curriculum syllabuses as "the relationship of the skeleton to the line of gravity and the base of support". For ideal alignment, your bones (rather than the muscles) should carry most of your body weight whereby the line of gravity pulls downward through the joints of the base of support along the vertical axis-in other words, each body part should be properly balanced over the part below. Alignment is not static- it is dynamic. There are rules to help achieve proper dynamic alignment. Particular attention should be placed on safe aligning of the head, shoulder girdle, spine, pelvic girdle, hip, knee and ankle joints and the feet. These are the principles of alignment.
Good posture is paramount for good ergonomic. It should be dynamic and strong. It is also affected by your individual body type. A good posture should keep you free from pain, allow you to stay flexible and provide the strength and motion necessary to perform your task without undue stress on any component of your body. Good posture is standing up straight, without your head tipped forward, your butt poked out or your shoulders rolled forward. You achieve it by getting strong core muscles and not tilting your head forward when you stand or sit, and roll your shoulders back. Imagine you have a string attached to the top of your head and it's pulling you upwards, that is what makes good posture.
Faulty Posture- Scoliosis
Scoliosis is a condition in which the spine bends to the side abnormally; either to the right or left. The curvature can be moderate to severe. Any part of the spine can be bent in scoliosis; but the most common regions are the chest area (thoracic scoliosis) or the lower part of the back (lumbar scoliosis). Those who do require treatment use a back brace, which is usually effective. A very small number of patients with scoliosis may require surgery. If left untreated, the condition can lead to serious spine, chest, pelvis, heart and lung damage
When scoliosis occurs, the spine can curve in one of three ways:
1. The spine curves to the side as a single curve to the left (shaped like the letter C), called levoscoliosis
2. The spine curves to the side as a single curve to the right (shaped like a backwards letter C), called dextroscoliosis
3. The spine has two curves (shaped like the letter S).
This type of kyphosis is the most common and causes a loss of height and interference with breathing. Technically, the term kyphosis can be used to describe any abnormal curve of the spine that goes in the backwards direction. So, in some instances kyphosis can be used to describe a reversal of the low back curve.
The term kyphosis also refers to the type of curve formed by the sacrum and the thoracic spine. When used this way, kyphosis refers to normal curvature. When looking at a side view of the spine, the direction of a kyphosis will be backwards. While kyphosis can occur at any age, it's most common in older women where the deformity is known as a dowager's hump. Age-related kyphosis often occurs after osteoporosis weakens spinal bones to the point that they crack and compress. A few types of kyphosis target infants or teens.
Safe Dance Principles
Safe dance principles are what help dancers move, stay active and exercise without the risk of an injury. All dancers need specific skills to follow the safe dance principles to make them a better dancer. Safe dance principles are awareness of how the body moves, correct alignment of the body, consistency, decreasing injury and increasing the dancers life in performance.
Exercises to Avoid
There are exercises that you should avoid to prevent injuries such as ballistic stretching (pulsing), straight leg sit ups, jumping into splits. You also need to remember to warm up before you dance.
