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 effect of this quadriga phenomenon is important in several clinical situations, including testing for strength, assessing movement of the tendons, and when deciding which exercises to teach the patient after a tendon injury.he quadriga syndrome is a condition in which the flexor. tendon excursion is reduced in an unaffected finger. when the excursion of the flexor digitorum profundus. (FDP) tendon of the adjacent finger is altered by stiff-. ness, injury, or adhesion (Verdan, 1960).
