    Learning Objectives
    • Name and describe the methods by which the muscle system contributes to homeostasis and quality of life.
    • Describe the effects of aging on four of the following parameters for muscle cells and describe practical effects on maintaining homeostasis and quality of life from these age changes.
    • Describe the effects of age changes in motor neurons and action potentials on muscle performance.
    • Describe the effects of age changes in neurons other than motor neurons (i.e., sensory, CNS) on muscle performance.
    • Describe the effects of age changes and disease changes in the circulatory system on muscle functioning.
    • Describe the effects of aging on muscle mass and name six effects from these changes.
    • Describe the effects of age changes in the muscle system on (1) reaction time, (2) speed of motion, and (3) skill.
    • Describe the effects of aging on the four aspects of stamina; i.e., performing extended vigorous activity.
    • Describe the effects of aging and changes in exercise on VO2 max and describe the effects from these changes.
    • Describe effects on the muscle system and three other systems - circulatory system, skeletal system, endocrine system; on quality of life; on diseases; and on life expectancy from staying physically active - i.e., maintaining high level of exercise.
    • Describe the effects from reducing levels of physical activity.
    • Describe effects on the muscle system and three other systems - circulatory system, respiratory, nervous, skeletal, endocrine system; on quality of life; on diseases; and on life expectancy from increasing activity when older.
    • Explain why exercise programs for older people must be individualized.
    • Name six important steps or considerations in planning an exercise program for elders.
    • Describe effects of age changes and abnormal changes on ability to drive motor vehicles.
    • Explain why driving a motor vehicle is important to many elderly.
    • List ways by which adequate transportation can be retained longer in spite of age changes.
