Effects of Power-velocity Muscle Characteristics During Ageing

Completed
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
NameTimeMethod
Differences in power-velocity characteristics during ageing1x 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
NameTimeMethod
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
