Final answer:
The elasticity of tendons and ligaments can increase with the application of heat, typically between 5% to 20%, but this can vary. Consulting a professional for personalized advice is recommended for safe practice.
Step-by-step explanation:
The application of heat can increase the elasticity of tendons and ligaments, possibly aiding in the flexibility and injury prevention during activities such as sports or physical therapy. While it is known that heat can help improve the elasticity of these tissues, the exact percentage increase varies depending on the individual and specific circumstances. In a controlled environment, studies have shown that increases can be in the range of 5% to 20%. Due to physiological variations and differences in methodology, there isn't a universally agreed-upon percentage. It is also important to apply heat properly to avoid potential injury. As such, it's best to consult with a healthcare professional or physiotherapist for personalized advice and safe practice.
