An educational tool for understanding the cardiovascular changes associated with diabetes

Area of Science:

• Physiology
• Exercise Science
• Endocrinology

Background:

• Diabetes mellitus is a metabolic disorder characterized by hyperglycemia and insulin deficiency.
• Diabetes is linked to cardiovascular complications and autonomic dysfunction, affecting homeostasis.
• Understanding diabetes' impact on physiological responses during exercise is crucial.

Purpose of the Study:

• To develop an accessible laboratory exercise for students to compare cardiovascular responses during exercise in diabetic and non-diabetic individuals.
• To enhance understanding of how diabetes affects the cardiovascular system's adaptive capacity.
• To provide a practical learning tool for analyzing physiological changes under stress.

Main Methods:

• The exercise involves analyzing provided anatomical and physiological data related to diabetes.
• Students interpret graphical representations of cardiovascular variables (heart rate, cardiac output, blood pressure) during exercise.
• Activities include answering questions, performing calculations, completing tables, and plotting graphs using basic tools like rulers and pencils.

Main Results:

• The laboratory exercise facilitates a comparative analysis of cardiovascular regulation in diabetes.
• Students gain experience in interpreting physiological data and applying cardiovascular principles.
• The exercise emphasizes problem-solving and data interpretation skills without requiring specialized equipment.

Conclusions:

• This laboratory exercise offers a unique approach to understanding the physiological impact of diabetes on cardiovascular function during physical exertion.
• It effectively integrates theoretical knowledge with practical data analysis, enhancing student comprehension of diabetes-related pathophysiology.
• The exercise promotes critical thinking and reinforces fundamental cardiovascular concepts in the context of a chronic disease.
