Diabetes is a chronic disease characterized by high levels of glucose in the blood. It is caused by a lack of insulin or a resistance to its action. Diabetes has been known for thousands of years, but as time passes there have been more and more discoveries about diabetes and the way it is diagnosed has been refined. In this investigation I will be investigating the effect of physical exercise on the blood glucose levels. For one minute, the study participants would exercise intensely, followed by a minute of rest. This will be repeated until they’d completed 10 minutes of intense exercise. The exercise sessions also included a warm-up and cool-down period. The best thing about this type of exercise is that these intervals can be scaled to each participant’s level of fitness so that it’s safe and effective for them. This means that each individual will exercise to an extent well suited for them so that there is no pressure on anyone as participants are not all on the same level of fitness.
Diabetes has become one of the major health threats of the 21st century. Despite the fact that the condition has history, there have been recent prevalence figures that show that the condition is far from getting better because of its massive increase. Condition having an age long history, recent prevalence figures show that numbers have increased drastically. The World Health Organization (WHO) estimated that in 2009, about 220 million people had diabetes globally, predicting that these numbers would rise to about 366 million by 2030. However, a more recent figure from the International Diabetes Federation (2016) has shown that there were already about 371 million people living with diabetes worldwide. In South Africa about 6 million people suffer from the disease. Of these 90% adults and 10% are children. There are several forms of diabetes but Type 1 and Type 2 are the most common. Regular physical activity, which can include structured exercise in a variety of forms, offers a great benefit for most individuals with diabetes.
Regular physical activity enhances insulin sensitivity, increases cardiorespiratory fitness, improves glycemic control, reduces the risk of cardiovascular mortality, and enhances psychosocial well-being. Muscles use glucose as fuel. Exercise also helps the body use insulin more efficiently, which in turn, helps the body use more glucose. Exercise can be categorized into two different types: aerobic and anaerobic, depending on the speed and force of muscle contraction and the utilization of energy substrates, these two categories of exercise have diverging effects on blood glucose levels of a person with diabetes.
