Older adults have a reduced ability in the translation of work from muscle fascicle shortening to the movement of the aponeurosis. Such non-invasive, high-SNR, large Field-of-view imaging with VE-PC techniques allow determination of physiological, clinically significant parameters with good accuracy and reliability
