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.
Strains. Muscles and tendons can become strained or pulled if they are stretched beyond their normal range of flexibility; a strained tendon is likely to experience soreness and possibly pain if its muscle is engaged.hronic Soreness. Tendon soreness may fade on its own without further sign of harm, but it can also potentially become a chronic problem due to conditions like tendonitis and tendinosis, where tendons become inflamed or accumulate damage over time.
