In Adulthood, When Maximum Oxygen Uptake and Cardiac Output Are

question 19

Multiple Choice

In adulthood, when maximum oxygen uptake and cardiac output are measured at rest, what is the usual age-based pattern? When maximum oxygen uptake and cardiac output are measured during exercise, what is the typical age-based pattern?

• A) At rest, there is a systematic decline of about 10% per year. During exercise, there is minimal decrement in capacity.
• B) During adulthood there is minimal age-based decrement in capacity of either of these functions when they are measured at rest or during exercise.
• C) Significant measures of age-based decline are found during rest, and even greater measures of decline in functioning are observed during exercise.
• D) Neither of these functions show significant declines when measured at rest, but when measured during exercise, both functions show systematic age-based declines.
