How much can tendon and ligament elasticity increase with heat application?

The correct answer indicates that tendon and ligament elasticity can increase significantly, up to 25%, with the application of heat. This increase occurs because heat enhances the elasticity of the collagen fibers present in tendons and ligaments. When these tissues are warmed, the molecular structure becomes more pliable, allowing them to stretch to a greater extent without injury. This improved elasticity is particularly beneficial during warm-up routines, as it can enhance flexibility and decrease the risk of strains and tears during physical activity.

Research in sports science supports the idea that thermal applications can lead to greater tissue extensibility, which is crucial for optimizing performance in strength training and conditioning. Therefore, the ability to improve flexibility and range of motion through heat application is a valuable aspect of athletic training and rehabilitation.
