How all the Body Systems
Relate to Irish Dance
By : Hanna drisko
Muscular System
muscular system effects how much you
lift and for how long. It is essential to
dance and main core muscles are essential
Such as hamstrings, quadriceps, and abs.
To improve fitness you do not have to lift
weights ,you can also do sit ups, push ups,
and calisth ethics.
Digestive system
follow the eat well plate that has
grains, dairy, lean protein, and fruit or
vegetables. Carbohydrate, fats, and
protein.(try not to eat fatty meats before
Irish dance).
Skeletal System
bones function in both their support and
movement functions. The bones and associated
joints of the gesture leg allow for the large
movement occurring at the right hip, while
those of the support leg are key for providing
stability so that the dancer can remain upright
despite a very small base of support. The
support function of bones requires that they be
strong, and understanding of bone remodeling is
key for preventing loss in bone strength
commonly seen in female dancers.
Nervous System
New movements are controlled by cerebral
cortex, and often feel awkward till the new
pathways are established and other parts of
nervous system learn to facilitate the
movement. (Pyramidal system, alpha and
gamma).
Training improves neuro-muscular
coordination. 'Repetition reinforces these
patterns and improves coordination, speed and
skill.' This is why repeating movements makes
your body able to do them more efficiently
Circulatory System
As you dance, your breathing quickens and as a result, your arterioles
(blood vessels) dilate which then causes your heart rate to increase. Your
resting heart rate is usually somewhere around 70 beats/min. Your
maximum heart rate is estimated roughly at 220 - your age. The more you
exercise your heart, the lower your steady-state heart rate will be (the
point at which your heart rate plateaus). Dancers generally have a lower
steady-state heart rate, as they will need to condition their bodies to be
able to dance for long periods at a time. During centre exercises such as
sautes and across the floor exercises, the body is having to continually start
and stop. If your class is fast paced and not too big, this is ideal, as your
body will not have a chance to rest as long and you will be exercising your
heart for a longer time. Since your body needs rich, oxygenated blood and
nutrients to survive and function properly, and the amount of blow flow to
the body dramatically increases from 20% at rest, to around 85% during
exercise, it goes without saying that the more exercise we get, the more
efficiently your body will function.
Immune System
A strong immune system enables you resist
and overcome infection. A strong immune
system is an essential requirement for survival,
since we are constantly being bombarded with
germs- viruses and bacteria that live inside and
outside of our bodies. When our immune
system is weak, we become a perfect host for
viruses and bacteria. Voila! we get sick. It’s not
the germs that make us sick, since we live with
germs all the time. It’s when our stress level
‘increases’, our immune function and resistance
‘decreases’.
Repertory System
When you dance or engage in physical exercise, your body
responds in a variety of ways. The main role of your respiratory
system is to bring fresh air into your body and to get rid of waste
gases. Your respiratory system experiences both short-term and
long-term exercise-associated benefits. The short-term benefits
include, an increase in your breathing rate and tidal volume (which
is the amount of air you inhale or exhale from your lungs in one
breath) which is a good thing, as the more clean, fresh oxygen we
breathe, the better we will feel, both inside and out. Some of the
long-term benefits include an improvement of the efficiency of your
respiration by strengthening your diaphragm and intercostal
muscles (the tiny muscles in between your ribcage which aid in
breathing) as well as increasing the total number of alveoli (the tiny
air-filled sacs where gas exchange occurs). Your circulatory system
then carries this new oxygen rich blood through your body to all
major organs and tissues, creating a much happier body as a whole.
