• Forces are oriented primarily in opposite directions
  • Tension stimulates muscle, tendon, ligament and in some cases neurological tissue.
  • Overload with “tension” leads to sprains, strains and in some cases peripheral nerve injury.
  • Examples: hamstring tear, patellar tendonopathy, brachial plexopathy, MCL tear. Insufficient loading leads to muscle atrophy, and weak ligaments and tendons for example.
