Joint
The area of articulation of two or more bones that allows
various types of motion, while some motion is practically
non-existent.
Joint
Stability
The resistance to displacement of the bones that make the
joint. Five factors provide joint stability: (1) The
shape of the bony structure. (2) Ligamentous Arrangement.
(3) Fascia or Fibrous Connective Tissue. (4) Atmospheric
Pressure. (5) Muscle Arrangement, Strength and Strength
Balance.
Jumper's
Knee
Patellar Tendinitis -- prevalent in jumping sports
(basketball, volleyball and weightlifting where squatting
is involved). This is an inflammation of the tendon that
connects the tibia to the patella. The caudal (head) side
of the patellar tendon connects to the powerful
quadriceps muscle. Onset is usually gradual and worsens
with overuse.
Jumping-Power
Tests
Tests to measure leg power are sometimes a part of
fitness or athletic evaluations. The short amount of time
of these tests probably does not actually correlate with
anaerobic power capacity. Two common tests are the
Sargent Jump-and-Reach Test and the Standing Broad
Jump.
