Do muscles have untapped elastic energy that can increase strength and add to training gains?

Yes, muscles possess untapped elastic energy primarily through the tendons and connective tissues that store elastic potential during stretching. This energy can be utilized to enhance performance, especially in activities involving explosive movements, such as sprinting or jumping. Incorporating exercises like plyometrics can help train the muscles to harness this elastic energy more effectively, potentially leading to increased strength and training gains. However, the extent of these benefits can vary among individuals and requires proper technique and conditioning.
