The MDC value of 49.17 cm corresponds to which hop test?

The MDC value of 49.17 cm corresponds to which hop test?

• A. Single leg hop for distance
• B. Single leg triple hop for distance
• C. Single limb crossover hop for distance
• D. Stair climb test

Answer: (C)

Minimal detectable change (MDC) is the smallest amount of change that likely reflects a real difference in performance rather than measurement error, usually reported with 95% confidence. In hop tests, MDC values vary because of how dependable the measurement is and how variable a person’s technique can be. The stair climb test yields a time score (seconds), not a distance in centimeters, so MDC expressed in centimeters wouldn’t apply there. Among hop tests that measure distance, the single limb crossover hop for distance tends to have the highest variability due to the crossing pattern and landing dynamics, which increases measurement error and pushes the MDC higher. That’s why a value like 49.17 cm best fits the crossover hop distance test. In practice, a change exceeding about 49 cm would be interpreted as real improvement beyond measurement error for this test.
