Stability of Physical Performance Test Scores

On each of three days 73 subjects were administered three trials of a standing broad jump test, and 48 subjects were administered five trials of a side-step test. A significant trial-to-trial variability within days was found for the side-step test. For both the standing broad jump and side-step tests a significant variability among days was found at the .05 level. These findings seem to indicate that a stable test score is not obtained the first two days a subject is administered a physical performance test.
