Abstract
A leg-protecting apparatus is arranged in close contact with a body surface of a wearer to cover a thigh, a knee, and a calf of the wearer, including a biomechanically protecting strap arranged to correspond with structural locations and paths of tendons and ligaments of the knee and muscles proximal thereto during an exercise process. The strap comprises a cruciate ligament protecting strap, a patellar tendon protecting strap, a thigh muscle group protecting strap, and a calf muscle group protecting strap. Elastic moduli of the cruciate ligament protecting strap and the patellar tendon protecting strap has a step-change upon a change in a fabric tensile ratio caused by the knee bending of the wearer, wherein the step-change occurs after an initial low tensile modulus stage, during a tensile sudden-change stage, and before a high tensile modulus stage transitioning between the stages as knee angle decreases.
