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).
