Increasing vertical jump by focusing on concentric acceleration post maximum eccentric or isometric contraction.
What do heavy eccentrics, iso holds and oscillation reps all have in common?
1. Emphasizes constant muscle tension even through deep ranges
2. (Important) Are followed by a neurologically maximal concentric contraction.
Q. Are the force production adaptations from these things due to the eccentric or iso nature of the movement or in the intent behind the concentric contraction following them?
1. Would if we focused on maximally accelerating concentrically following supramax eccentric heavy movements (even overspeeding the concentric if needed)
2. We rarely focus on the final concentric contraction following a long duration or osci Iso. It happens to an extent because of the nature behind trying to get out of the position, but would if the intent focused on acceleration post isometric?
I think of it like a rubber band.
The eccentric being- pulling back the rubber band creating tensions.
The isometric - stretching the rubber band to its max potential.
The concentric - the byproduct of stored energy and the rubber band fires
If the concentric is hindered I see it as benefiting strength (example: weight releasers), but if the acceleration of the concentric can be maximized I see it as possibly benefiting speed and elasticity
