/Highlights/ How to test whether accelerometer has been calibrated at all? Dr Timo Rantalainen

Dr Timo Rantalainen - Accelerometry | Gait | Elderly In this episode, we have Dr Timo Rantalainen, who is Research Fellow at the Gerontology Research Center, Faculty of Sport and Health Sciences, University of Jyväskylä, Finland. Dr Rantalainen’s area of expertise pertains to neuromuscular and skeletal systems, specifically skeletal adaptation to mechanical loading and neural control of muscles, with a focus on estimating lower limb loading and bone responsiveness. His current research interests include: 1) the effect of loading on bone geometry, 2) neuromuscular function of muscle, 3) muscle and bone adaptations with age, and 4) the measurement of bone geometry using peripheral quantitative computed tomography (pQCT). --- This podcast episode is sponsored by Fibion Inc. | The New Gold Standard for Sedentary Behaviour and Physical Activity Monitoring Learn more about Fibion: https://fibion.com/research --- Physical Activity Researcher Podcast have created a ‘Purchase Guide for Researchers: Accelerometer-based Activity Trackers’.
