The purpose of this study was to investigate if force enhancement (FE) in vivo is influenced by stretch-induced changes of muscle architecture. Therefore, 18 subjects performed maximum voluntary isometric (100 degree knee flexion angle) and isometric-eccentric-isometric stretch contractions (80 degrees-100 degrees; ω=60 degrees.s(-1)) whereby pennation angle and fascicle length of vastus latera...

Isometric evaluation of hip and knee muscle strength can be a useful objective assessment tool in the clinic and may be preferred over other forms of dynamic muscle testing, such as isokinetic assessment or variable-resistance weight-lifting. Assessment of isometric strength with use of a handheld dynamometer requires little skill and is easily administered, relatively inexpensive, valid, relia...
