Muscle Contraction: Eccentric, Amortization, Concentric SSC works in 2 ways: 1: Neurophysiologic (Muscle Spindle activation) 2: Mechanical (Tendon stretch/ Series Elastic Components) Stretch Shortening Cycle Training Adaptation: Faster the Countermovement the more contribution from the SSC Too long of ground contact time= SSC dissipates as heat Good ground contact time tends to be less than around 0.25 seconds Extending time longer increases muscle tension closer to peak and may activate GTO Depth Jump height of around 30-32 inches seems to be optimal for most athletes Also, it’s important to consider that Training increases muscle stiffness not elasticity. This can improve Reactive Strength Index: Jump height / Ground contact time Make sure you check out some of the other CSCS Prep Videos I have done: CSCS Nutrition:    • CSCS Nutrition Calculations: Calories...   CSCS Work to Rest Ratios:    • NSCA CSCS Work to Rest Ratio Explaine...   Muscle Levers:    • Muscle Levers 1st Class, 2nd Class, 3...   Olympic Lifting Technique:    • Olympic Lifting Technique: Snatch, Cl...   Comment below if you have any questions! 🧠 Learn more at www.themovementsystem.com This is the CSCS Practice Test that I recommend: https://www.themovementsystem.com/off...
