Effects of Power-velocity Muscle Characteristics During Ageing

May 18, 2022 updated by: Universitaire Ziekenhuizen KU Leuven
The purpose of this project is to investigate the age-related differences in force-velocity muscle characteristics during isolated knee extensions variable in speed and load, during cyclic movements on a usual and recumbent bike variable in speed and velocity development and a functional test battery with healthy participants aged between 20-80 years.
