... characteristics were measured in an ankle dynamometer using simultaneous motion-capture-assisted ultrasonography. Oxygen consumption and ankle kinematics were also measured on a treadmill at the marathon pace. All measurements were performed before and after the marathon. AT stiffness did not change significantly...

... which tendon elongation was measured using ultrasonography and two cameras. Tendon force was calculated by dividing measured ankle torque by magnetic resonance imaging-derived AT lever arm length. Tendon stiffness remained unchanged, being 430±200 N mm −1 before and 390±190 N mm −1 after the exercise...

... MRI ultrasonography tendon plasticity in vivo exercise strain Mechanical load induced as cyclic strain, imposed externally to fibrous connective tissues such as tendons, may induce several signals at the extracellular matrix. This happens through mechanotransduction pathways affecting...

The caimans showed the same rapid and reversible changes of organ size and identical histological features...

... the alternative idea that external handling times constrain intake rate). Gizzard size within individual birds was manipulated by varying the hardness of the diet on offer, and was confirmed by ultrasonography. The results upheld the `shell-crushing hypothesis' and rejected the `handling time hypothesis'. Intake...

...Constantinos N. Maganaris; John P. Paul ABSTRACT In the present study, we measured the in vivo load–elongation characteristics of the human tibialis anterior tendon and its central aponeurosis. Measurements were taken in five men using dynamometry, muscle electrical stimulation and ultrasonography...
