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.
The extensor tendons are a group of tendons on the top of the foot. They start up in the front of the leg (in the anterior anatomic compartment) and pass down the leg along the shin, in front of the ankle, and across the top of the foot at they head out into the toes. They lie just under the skin on the top (dorsal surface) of the foot.
