Effects of Power-velocity Muscle Characteristics During Ageing
- Conditions
- Sarcopenia
- Registration Number
- NCT02692612
- Lead Sponsor
- Universitaire Ziekenhuizen KU Leuven
- Brief Summary
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.

- Primary Outcome Measures
Name Time Method Differences in power-velocity characteristics during ageing 1x at baseline (cross sectional study) 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
- Secondary Outcome Measures
Name Time Method Reliability of strength tests on regular and recumbent bike. 1x at baseline (cross sectional study) reliability of peak power and rate of power development outcomes measured twice within a period of 2 weeks
Differences in muscle activation during ageing. 1x at baseline (cross sectional study) Differences in muscle activation pattern during dynamic leg press movements measured via muscle electromyography
Differences in muscle fascicle characteristics during ageing. 1x at baseline (cross sectional study) Differences between young and old people of fascicle shortening velocity during dynamic leg press movements measured via dynamic ultrasound
