Validation of the RT3 triaxial accelerometer for the assessment of physical activity
Article Abstract:
A study to assess and compare the validity of the RT3 accelerometer for assessing the physical activity in boys and men and to compare RT3 and Tritrac accelerometer counts as well as determine cut-off values for moderate and vigorous activity for both is presented. Results show that RT3 accelerometer is a good measure of physical activity and its counts are significantly higher than Tritrac counts for a number of activities.

Intermonitor variability of the RT3 accelerometer during typical physical activities
Article Abstract:
Eight RT3 accelerometers are subjected to two repeated trials of rest, walking, running, and sit-stand position to determine the reliability and variability of the machines. The results demonstrate intermonitor coefficient of variation to be less than 6% during locomotive activities but increased to 8-25% during sit-stand and the vertical axis shows the least variability and is the most reliable.

Technical variability of the RT3 accelerometer
Article Abstract:
Results show inter- and intra-instrument variability in the RT3 accelerometers. Data indicate that the Y axis consistently reads higher than the X and Z at 5.1 and 10.2 Hz.
