: Your tendons—especially the massive Achilles tendon —act like high-tension springs. They don't just stay still; they deform and stretch, soaking up kinetic energy and storing it as elastic potential energy . Chapter 2: The Crossroads (The Amortization Phase)

: As your quads and calves lengthen to absorb the impact, specialized sensory receptors called muscle spindles act as tripwires. They sense the rapid stretch and immediately send an urgent signal to your spinal cord: "We're stretching too fast—contract now!" . Plyometric anatomy

In a trained athlete, plyometrics "desensitize" these brakes, allowing the body to tolerate higher workloads without hitting the "abort" button.
