Parkinsons is a
degenerative disease where the brain cells that affect the control of movement
slowly dies, resulting in disturbances in the messages being relayed from the
brain to muscles. This inhibits or negatively affects movement. This mechanism
can be explained physiologically by a chemical produced in the brain cells
called dopamine, which is used by the nerve cells to help control movement.
When an individual has Parkinson’s, these brain cells die making it hard to
control the muscles involved in movement. Another factor involved in the
neurological damage is the occurrence of protein misfolding and formation of
distinct aggregates. This results in a putative pathological protein load on
the nervous system. Symptoms of parkinson’s occurs when there is more than an
80% loss of dopaminergic cells.
Symptom
Classic symptoms
of Parkinson’s include:
1.
Rigidity
and trembling of head
2.
Forward
tilt of trunk
3.
Reduced
arm swinging
4.
Rigidity
and trembling of extremities
5.
Shuffling
gait with short steps
Parkinsons is an
idiopathic condition, therefore it is not clearly known what causes the cells
to waste away. Parkinsons is a highly researched disease to help us possibly
prevent and treat it better.
Speculated causes:
- · genetics
- · mitochondrial dysfunction and antioxidants
- · occupational exposures (pesticides, herbicides, and heavy metals)
- · smoking, coffee, and alcohol.
Exercise and Parkinsons:
Research over the last couple of years has uncovered
a large amount of evidence that exercise is an effective form of treatment for
Parkinson’s disease and could delay the steady decline of the disease. Studies
using animals found that exercise has protective benefits towards the onset of
Parkinsons symptoms. This appears to be due to the release of neurotrophic
factors, greater cerebral oxygenation which both promote new cell growth and
survival.
Exercise helps stimulate dopamine synthesis in the
remaining dopaminergic cells, thus reducing symptoms. Research suggests
exercise enhances neuroplasticity in Parkinson’s patients via 5 key principles:
1. Intense
exercise maximizes synaptic plasticity
2. Complex
exercise promote greater structural adaptation
3. Rewarding
activities increase dopamine levels which promotes learning/relearning
4. “Use
it or Lose It” phenomenon (dopaminergic neurones are highly responsive to
exercise and inactivity)
5. Exercise
if done early slows down the progression of the disease.
Taking into
account these 5 key principles of exercise and Parkinson’s disease, exercise
has shown to provide many benefits to Parkinson’s patients such as:
·
Increased
health related quality of life
·
Decrease
in disease severity
·
Increased
muscle strength
·
Increased
aerobic capacity
·
Increased
physical functioning
·
Increased
balance
·
Improvement
in walking speed/ability
