- Introduction
-
-
-
- For our seminar topic "physical activity and disease" we chose diabetes as the focus of our
- research.
-
- Since diabetes is such a complex disease with many different forms, we decided to focus on
- diabetes type I. This is known as insulin-dependent diabetes mellitus (IDDM). This type of
- diabetes includes people who are dependant on injections of insulin on a daily basis in
- order to satisfy the bodies insulin needs, they cannot survive without these injections.

- OVERVIEW OF DIABETES TYPE I
-
-
- What is diabetes type I?
-
- In order to understand the disease we firstly need to know about insulin. Insulin is a
- hormone. The role of insulin is to convert the food we eat into various useful substances,
- discarding everything that is wasteful.
-
- It is the job of insulin to see that the useful substances are put to best use for our
- well-being. The useful substances are used for building cells, are made ready for immediate
- expenditure as energy and also stored for later energy expenditure.
-
- The cause of diabetes is an absolute or lack of the hormone insulin. As a result of this
- lack of insulin the processes that involve converting the foods we eat into various useful
- substances does not occur.
-
- Insulin comes from the beta cells which are located in the pancreas. In the case of
- diabetes type I almost all of the beta cells have been destroyed. Therefore daily
- injections of insulin become essential to life.
-
- Health implications of diabetes type I
-
-
- One of the products that is of vital importance in our bodies is glucose, a simple
- carbohydrate sugar which is needed by virtually every part of our body as fuel to function.
-
- Insulin controls the amount of glucose distributed to vital organs and also the muscles. In
- diabetics due to the lack of insulin and therefore the control of glucose given to
- different body parts they face death if they don't inject themselves with insulin daily.
-
- Since strict monitoring of diabetes is needed for the control of the disease, little room
- is left for carelessness. As a result diabetic patients are susceptible to many other
- diseases and serious conditions if a proper course of treatment is not followed.
-
- Other diseases a diabetic is open to: Cardiovascular disease, stroke, Peripheral artery
- disease, gangrene, kidney disease, blindness, hypertension, nerve damage, impotence etc.
- Basically there is an increased incident of infection in diabetic sufferers. Therefore
- special care needs to be taken to decrease the chances of getting these other serious
- diseases.
-
-

-
- PHYSICAL ACTIVITY
-
- What is physical activity?
-
- (Bouchard 1988) States that physical activity is any bodily movement produced by skeletal
- muscles resulting in energy expenditure. Therefore this includes sports and leisure
- activities of all forms.
-
- Why do we need physical activity in our lives?
- Physical activity and exercise helps tune the "human machine", our bodies.
-
- Imagine a car constantly driven only to stop for fuel. It would be a client for all sorts
- of damage, rusting, oil leaking, dehydration and the chances are most likely it would die
- in the middle of the road not long after. This is what the body would be like if we didn't
- exercise at all. We would be and as a result of todays lifestyle many of us are, the
- perfect target to all kinds of diseases and infections.
-
- For those of us who are carrier of some disease or illness we are still encouraged to
- exercise by our physicians if we have the strength to. This is to help make our organs,
- muscles, bones and arteries more efficient and better equipped to fight against the disease
- or illness. This is our way of counter attacking. And if we are still healthy then we
- reduce the chances of getting an illness or a disease.
-
- PHYSICAL ACTIVITY AND DIABETES (EPIDEMIOLOGY)
-
- Recently insulin injections have become available to dependant patients. However in the
- pre-insulin era physical exercise was one of the few therapies available to physicians in
- combating diabetes.
-
- For an IDDM carrier to benefit from exercise they need to be well aware of their body and
- the consequences of exercising.
-
- If an IDDM carrier has no real control over their situation and just exercise without
- considering their diet, time of insulin intake, type of exercise, duration of the exercise
- and the intensity, then the results can be very hazardous to the patient.
-
- In the first journal article that I used for this part of the research (Sutton 1981) had
- conducted an investigation on "drugs used in metabolic disorders". The article is designed
- to provide some background information on previous beliefs and research conducted early
- this century. As well as his own investigations conducted during the beginning of the
- 1980's. He has compared the results and came to the same conclusion as the investigations
- done early in this century.
-
-
- Sutton's findings show that decrease in blood glucose following an insulin injection was
- magnified when the insulin was followed by physical activity/exercise (see figure 1). This
- shows that if a person gets involved in physical activity or exercise after insulin the
- volume of glucose drops dramatically. This leads to symptoms of hypoglycemia. The reason
- this occurs is that glucose uptake by muscles increase during exercise, in spite of no
- change or even a diminishing plasma insulin concentration. As a result of this type of
- information we know now that if a patient is not controlled through a good diet and program
- then they could put themselves in danger. A person who might be poorly maintained and
- ketotic will become even more ketotic and hypoglycimic.
-
- Good nutrition is of great importance to any individual especially one that exercises. In
- the case of diabetes even more consideration must go into the selection of food before and
- after exercise. Doctors suggest large intakes of carbohydrates before exercise for diabetes
- carriers to meet the glucose needs of the muscles.

- The second article that I used was that of Konen, et al. He and his colleagues conducted
- testing and research on "changes in diabetic urinary and transferrin excretion after
- moderate exercise". This article was a report of the way the research was conducted and
- it's findings.
-
- The researched found that urinary proteins, particularly albumin, increase in urinary
- excretion after moderate exercise. Albumin which is associated with micro- and
- macrovascular diseases in diabetic patience was found to increase significantly in IDDM
- patients, while remaining normal in non-diabetics. (See table 1 and 2 for results)

-
-
- These results cannot be conclusive to say that this shows that exercise causes other micro-
- and macrovascular diseases in diabetics. Since albumin is not associated with any disease
- in non-diabetics then the same may be the case for diabetics as well. However further
- research is required to find out why such a significant increase occurs in diabetic
- patients and what it really means.
-
- It obvious that there are many very complicated issues associated with diabetes which
- cannot be explained at this stage. Therefore much more research is required and it's only a
- matter of time for these complications to resolved.
-
- Although there are no firm evidence to suggest that exercise will improve or worsen
- diabetes still it is recommended by physicians.
-
- Aristotle and the Indian physician, Sushruta, suggested the use of exercise in the
- treatment of diabetic patients as early as 600 B.C. And during late last century and early
- this century many physician claimed that the need for insulin decreased in exercising
- patients.
-
- The benefits of exercise in non-diabetic individuals is well known. For example reduce the
- risk of heart disease. This makes exercise very important to diabetic carriers since they
- are at a greater risk of getting heart disease than non-diabetics.
-
- Unquestionably, it's important for diabetics to optimise cardiovascular and pulmonary
- parameters as it is for non-diabetic individual. Improved fitness can improve one's sense
- of well-being and ability to cope with physical and psychological stresses that can be
- aggravated in diabetes.
-
- In well controlled exercise programs the benefits are many, as shown on table 3.

- CONCLUSION
-
-
- In conclusion we can see that although there are many factors that need to considered when
- a diabetic person exercises, still there are many benefits when an IDDM carrier controls
- and maintains a good exercise program. The risks of other disease such as heart disease and
- obesity are reduced.
