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.
Muscle and tendon injuries are often obvious because of local pain and swelling. Initially the injury may be underestimated as patientsâ are often reluctant to move local joints when they are sore from injury. Joint movement should return within days if the muscle/tendon is intact.uscle and tendon injuries are often obvious because of local pain and swelling.
