The Differential Effects of Mechanical Loading on Tendons[1][edit | edit source]

Mechanical Load Level Effects on Tendon

Low

• ↓ Tensile strength
• ↓ Size
• ↓ Collagen production
• ↓ Anabolic activities
• ↑ Catabolic activities

Moderate

• ↑ Tensile strength
• ↑ Collagen synthesis
• ↓ Collagen degradation
• ↓ Adhesions
• ↓ Inflammatory mediator (e.g. prostaglandin E2, PGE2)
• ↑ Tendon stem cells (TSCs) differentiating into tenocytes

Excessive

• ↓ Tensile strength
• ↓ Collagen organization
• ↑ Myofibroblasts
• ↑ Inflammatory mediators
• ↑ TSCs differentiating into nontenocytes (adipocytes, osteocytes, chondrocytes)
• ↑ Leukotrienes (↑ edema)
