Measure of within-subject measurement error. It represents how much a performance measure may vary if the test is repeated on the same individual (e.g., how much CMJ jump height measurements from the Output Sports IMU fluctuate due to measurement error across multiple CMJ trials from the same individual). SEM is a measure of the device’s absolute reliability for repeated measures from the same individual (1, 2).
