To cause a significant effect through a strike, what duration of energy transfer is necessary?

To achieve a significant effect through a strike, energy transfer must occur over a brief but specific duration. Approximately 30 milliseconds is often recognized as a threshold that allows enough time for the body to properly absorb and respond to the energy being delivered through the strike. Striking with this duration enables the necessary kinetic energy to penetrate deeply enough into the target to cause effective damage, whether through physical pain or incapacitation.

In less than 30 milliseconds, the energy transfer might not provide sufficient time for the muscles and structures involved to react adequately, possibly leading to a lack of impactful effect. Conversely, a duration of more than 30 milliseconds could lead to diminished effectiveness, as the target may have a better chance to react or evade. The option of zero milliseconds is impractical since no energy transfer occurs without at least some measurable duration.

Understanding this timing aspect is critical in defensive tactics, where quick and effective strikes can enhance personal safety and defensive success.
