Research Abstract |
In this study, the muscle hardness of the plantar flexors was determined using ultrasound real-time tissue elastography and two types of custom-made tissue mimicking materials of known hardness and its relations with muscle strength and volume were examined. It was shown that the muscle hardness with no passive tension depends on the muscle size but does not relate to the muscle strength. Thus, it is suggested that interindividual differences in muscle strength per size are not significantly influenced by differences in muscle hardness.
