Abstract:Stress fractures are a common running injury which often occur at the tibia and are the result of repeated loading on the bone. Peak tibial acceleration (PTA) has often been used as an indicator of tibial bone loading (TBL), but a validation of this metric is lacking. This study compared agreement between PTA and TBL across different speeds, step frequencies (SFs) and accelerometer locations. Nine trained runners performed a protocol on a treadmill consisting of running nine trials at 10, 12 and 14 km/h at preferred SF, 10% above preferred SF and 10% below preferred SF. Correlations between PTA and TBL were mostly absent. The findings indicate that the use of PTA as an indicator of the forces acting on the tibia might not be appropriate. An increase in PTA should thus not directly be assumed to also mean an increase in TBL or a higher risk on an overuse injury at the tibia. However, more research is needed on the validity of the used TBL metric. This research has added to the existing research on using PTA as an indicator of tibial bone loading. Key words: peak tibial acceleration, running, tibial bone load, inertial measurement unit
