Answer

To determine why dynamic flexibility tests are not used as often as static flexibility tests, we can analyze the provided options one by one.

A. Dynamic flexibility tests involve more subjective measurements.

B. Static flexibility tests are less expensive to perform.

C. Dynamic flexibility tests do not provide useful data.

D. Static flexibility tests are more difficult to standardize.

Given this analysis, the most compelling reason among the choices for why dynamic flexibility tests are not used as often as static tests is:

A. Dynamic flexibility tests involve more subjective measurements.

This is the best answer since subjective measurements can lead to variability in testing and results, making static tests more favorable for consistent and reliable data collection.
