Knockout power is a similar concept relating to the probability of any strike to the head to cause unconsciousness or a strike to the body that renders an opponent unable to continue fighting.
Knockout power is related to the force delivered, the timing, the technique, precision of the strike, among other factors.
The core is perhaps the most important element in a powerful punch, since it connects the powerhouse of the legs to the delivery system of the arms.
While the core may be important, experienced boxers have greater contributions from the legs compared to less experienced boxers meaning strong powerful legs are the foundation for punching power.
[2] When it comes to throwing a powerful jab, one must take a lead step forward to allow the body's momentum to carry forward with a braced lead arm to transmit this momentum to the target.
