Not per the kinetic linking video, my post #5 and study on boxing's straight punch:To me the kinetic linking explains both cases, doesn't it? So there is no conflict, they are complementary methods?
Trunk Rotation in Straight Punches (kinetic linking).At this stage, boxers used the lead leg as a pivot point and executed straight punches such that only lead leg supported the body weight and the rear leg bore no GRF. At this stage, GRF of the rear leg decreased, while GRF of the lead leg increased, which was exactly opposite from the starting position or the first stage.
In the OP, Choi throws the jab from neutral position (down), moves up, drops back to neutral position (down) then strikes to generate power. It's gravity: down -> up -> down vs kinetic linking: up -> down -> up.It seems Choi is stepping forward to the quick, and utilises gravity to reflect the kinetic wave and add power to the strike, this is why he syncs the strikes with the up -> down.
The other examples, does not use gravity, it reflects the kinetic wave from the ground, and uses an upwards push to add power, thus the strik is synced with down -> up.
Choi's gravity sine wave in the jab-reverse punch has less:
- Trunk rotation
- Whole body torque
- Power come from back -> forth
- Angle
- Momentum towards the target
- Weight transfer
- Elastic energy
- Punch accuracy
- Non-telegraphing
- Follow through
In Tyson vs Golota, Tyson...
1. from neutral position (up) simultaneously fakes a jab to the right of Golota's head, slips (defense) to his right (down) and steps forward and to the left with his lead foot. Now, Tyson's weight is on the back foot with his head on the left side of Golota's head.
2. pushes off his back foot crosses the centerline as he shifts his weight to the front foot (up). Tyson's head is now on the right side of Golota's head. Tyson follows through with the rear straight, at a trajectory where Golota cannot brace his head, knocking Golota down.
Tyson's jab-reverse punch is different and has the missing elements from Choi's sine wave.
Yes. Boxing can also use gravity with the jab, Dempsey falling step. Sine wave works better if target is down (e.g., breaking boards below you). Boxing and MMA also punch when moving back but use the more powerful kinetic linking, rather than gravity.Even in kyokushing we do both methods depending on the attack and movement combination. I think it comes natural, to work with gravity whe nyou strke down, and push off the ground when striking upwards. For pure horizontal strikes I think both methods partially would work, but not sure which one is more powerful. I thikn it depends on where your feet are at the impact?
