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.
