Sarcopenia
Conditions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 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 |
| 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 |
