In Adulthood,when Maximum Oxygen Uptake and Cardiac Output Are Measured

question 17

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