Effects of isometric squat training on the tendon stiffness and jump performance.

Conclusion. These results suggest that isometric squat training changes the stiffness of human tendon-aponeurosis complex in knee extensors to act negatively on the effects of pre-stretch during stretch-shortening cycle exercises.
