Hey /fit/,I've been doing shock plyometrics at the insistence of my football coach (I have the slowest 40 yard dash on the team), and have noticed some progress. When I read up on it, I learned that depth jumps depend on loading your muscles with force (Ex.: jumping from one meter at 100kg, so the Force would = Mass (100kg)x Acceleration (19.8m/s/s, in this case, so 19.8), so your muscles are loaded with 1980kg of force if you resist hard enough not to buckle under the fall. This momentary maximal contraction is called the "shock."I noticed that if I just jump up and then stomp my feet into the ground as fast as I can, I feel something that feels literally like a shock in my calves, quads, and glutes. What is this, and does this have any training applications? Or should I just stick with depth jumps?
