An educational tool for understanding the cardiopulmonary changes associated with aging

Area of Science:

• Physiology
• Gerontology
• Exercise Science

Background:

• Normal aging involves significant cardiac, vascular, and pulmonary adaptations impacting homeostasis.
• Understanding these age-related physiological changes is crucial for maintaining health and function.

Purpose of the Study:

• To develop an interactive laboratory exercise comparing cardiopulmonary responses to exercise in young versus older individuals.
• To enhance student learning through active engagement in analyzing and interpreting physiological data related to aging.

Main Methods:

• The exercise provides anatomical and physiological data on aging.
• Students analyze figures illustrating cardiopulmonary variables (heart rate, cardiac output, blood pressure) during exercise.
• Activities include data analysis, calculations, graphing, and problem-solving without specialized equipment.

Main Results:

• The exercise facilitates the analysis and interpretation of age-associated changes in cardiopulmonary function.
• It emphasizes the application of basic science principles and problem-solving skills.
• An evaluation instrument was developed to assess the instructional tool's effectiveness.

Conclusions:

• This laboratory exercise offers a practical approach to understanding the physiological impact of aging on cardiopulmonary function during physical activity.
• Active learning through data interpretation enhances comprehension of complex physiological adjustments.
• The tool effectively integrates scientific principles with practical application for academic settings.
