A vertical jump or vertical leap is the act of raising one's center of gravity higher in the vertical plane solely with the use of one's own muscles; it is a measure of how high an individual or athlete can elevate off the ground (jump) from a standstill. Contents.
Tendon excursion takes place as the muscle contracts and the joint rotates. The amount of tendon excursion is related to the amount of the joint rotation. A pulley-type constraint keeps the tendon path close to the bone when the tendon crosses a joint.roper excursion and gliding of the tendon determine the efficiency of this function. Studies of the tendon excursion and gliding based on two simple mechanical concepts have resulted in several significant clinical implications.
A peroneal tendon injury is a problem with the tendons and muscles on the outer side of your lower leg and foot. Tendons are strong bands of tissue that attach muscle to bone. The peroneal tendons help keep your foot and ankle stable when you walk. Tendons can be injured suddenly or they may be slowly damaged over time. You can have tiny or partial tears in your tendon. If you have a complete tear of your tendon, it is called a rupture.
