| Popis: | BACKGROUND: Physical activity (PA) may need to produce high impacts to be osteogenic.AIMS: to identify threshold(s) for defining high impact PA for future analyses in the VIBE (Vertical Impact and Bone in the Elderly) study, based on home recordings with triaxial accelerometers.METHODS: Recordings were obtained from 19 Master Athlete Cohort (MAC; mean 67.6 years) and 15 Hertfordshire Cohort Study (HCS; mean 77.7 years) participants. Data cleaning protocols were developed to exclude artefacts. Accelerations expressed in g units were categorised into three bands selected from the distribution of positive Y-axis peak accelerations.RESULTS: Data was available for 6.6 and 4.4 days from MAC and HCS participants respectively, with approximately 14 hours recording daily. Three-fold more 0.5-1.0g impacts were observed in MAC versus HCS, 20 fold more 1.0-1.5g impacts, and 140 fold more impacts >1.5g.CONCLUSIONS: Our analysis protocol successfully distinguishes PA levels in active and sedentary older individuals. |
