The jump height may alsobe calculated by applying the workâenergy theorem to theforceâdisplacement curve, again using numerical integration.II. FORCE PLATFORMForce platforms have a wide range of applications, includ-ing automobile crash tests, clinical gait analysis, and sportstechnique analysis.
However, severe forces or repetitive force over time can cause tiny microtears in tendon tissue, leading to injury. Tendinitis is inflammation (redness, swelling, heat, soreness) that occurs when the body's immune system detects an injury and responds. In the case of tendinitis (also spelled âtendonitisâ), the body increases the flow of blood and infection-fighting substances to the injured tendon. Tendinosis is a degenerative injury to the tendon that doesn't provoke an immune response. It occurs when repetitive, unrelenting stress over time causes the breakdown of collagen, growth of abnormal blood vessels, and thickening of the tendon's sheath (covering).
Biceps tendinitis is inflammation of the tendon around the long head of the biceps muscle. Biceps tendinosis is caused by degeneration of the tendon from athletics requiring overhead motion or from the normal aging process. Inflam-mation of the biceps tendon in the bicipital groove, which is known as primary biceps tendinitis, occurs in 5 percent of patients with biceps tendinitis. Biceps tendinitis and tendinosis are commonly accompanied by rotator cuff tears or SLAP (superior labrum anterior to posterior) lesions.
