( Agyapong-Badu, Warner, Samuel, & Stokes, 2016 ), and there are no data about age-related changes in tendon mechanical properties measured with this equipment. Strain elastography (SE) using ultrasound also allows a noninvasive assessment of tissue mechanical properties ( Park & Kwon, 2011 ). The SE, based

Shear wave elastography (SWE), an expansion of traditional ultrasound, is an imaging technique used to measure the material properties of soft tissues. This is done by noninvasively quantifying the material properties of the tissues in real time. Images are produced by shear waves sent into the

Shear-wave elastography is a technique that was developed to analyze tissue quality, with a focus on elasticity. 17 Shear-wave elastography provides noninvasive quantitative and local elastic information on soft tissues in real time, based on viscoelastic properties. 17 The

Some of the studies assessing muscle tissue are dealing by the means of strain elastography, in which the examiner manually

A common complication associated with aging is the stiffening of skeletal muscles. The purpose of this study was to determine the ability of magnetic resonance elastography (MRE) to study this phenomenon in vivo. Twenty female subjects were included in the study with an age range of 50 to 70 years. Shear modulus was calculated for the tibialis anterior of each subject. There was not a significant relationship between age and shear modulus. However, three subjects had abnormally high values and were among the oldest subjects tested. There was a significant relationship between age and tissue stiffness homogeneity. More research is needed to determine whether the changes seen here are reflective of increased tissue cross-linking or related to reduced muscle quality. However, MRE shows promise as a tool to study aging-related muscle stiffness changes or to evaluate treatments to counteract these changes.

elasticity of the TrA was measured at rest and during hollowing with maximum effort through ultrasonography (HI VISION Avius; HITACHI Aloka Medical, Tokyo, Japan) with the SL-18-5 linear ultrasound transducer in real-time tissue elastography mode. The probe was set to the target region parallel to the muscle

However, no studies have compared the elastic moduli of the hip flexor and shoulder muscle or the lumbar extension angle during a DK between swimmers with
