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.

Definitions:

Sign Test Statistic

A sign test statistic is used in non-parametric statistics to determine if two dependent samples come from the same distribution, focusing on the direction of changes rather than their sizes.

Distribution

Refers to the way in which something is shared out among a group or spread over an area.

Sign Test Statistic

A non-parametric statistical test used to evaluate the consistency of results with a hypothesized median by considering only the signs of the differences, not their magnitude.

Normally Distributed

Describes a dataset that follows a Normal distribution pattern, showcasing a bell-shaped curve when plotted.
