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.

Differences in power-velocity characteristics during ageing
peak power and rate of power development (slope) at different velocities during knee extension movement and cyclic multijoint leg press movement compared between young and old people
Time frame: 1x at baseline (cross sectional study)
Reliability of strength tests on regular and recumbent bike.
reliability of peak power and rate of power development outcomes measured twice within a period of 2 weeks
Time frame: 1x at baseline (cross sectional study)
Differences in muscle fascicle characteristics during ageing.
Differences between young and old people of fascicle shortening velocity during dynamic leg press movements measured via dynamic ultrasound
Time frame: 1x at baseline (cross sectional study)
Differences in muscle activation during ageing.
Differences in muscle activation pattern during dynamic leg press movements measured via muscle electromyography
Time frame: 1x at baseline (cross sectional study)
