Myotendinous junction & muscle fibers response to heavy resistance training

The myotendinous junction (MTJ) as the interface between muscle and tendon is known to be the weakest link in the muscle-tendon chain, and ultrasonographic visualization of muscle strain injury in humans indicates that tissue damage involves the MTJ. Microscopy of experimental load-to-failure strain injuries in animals has revealed that the actual site of rupture is…

Technical difference’s in Volleyball players show shoulder anatomical adaptation


In elite volleyball players, repetitive spiking unevenly burdens the (DOM) dominant shoulder, which can result in adaptations or injuries. Spiking consists of the cocking, acceleration and deceleration phases. In the cocking phase, the dominant arm abducts and externally rotates in preparation for forceful adduction and internal rotation in the acceleration phase. Finally, the hand decelerates…

Does Ultrasound really image deliver optimal tendon imaging?


I have to declare that in my clinical practice, I do not use ultrasound to image the patellar or achilles tendon – I use MRI imaging in combination with expert musculoskeletal radiologists – so perhaps I have a bias in feeling that US is often used to demonstrate a clinical suspicion and is very very…
