ALL ABOUT FRONT KNEE FLEX

TM

RESEARCH AND DEVELOPMENT

Front Knee Flex (FKF) is the flexing of the front knee right after front foot strike. This is the absorption of energy in preparation to transfer its linear motion upwards into the hips.


The front knee acts as a transfer station within your kinetic chain reaction (KCR). FKF efficiency determines how much energy will move from your lower half into your upper half. The less elasticity in FKF, the more loss of energy.


MECHANICAL COMPENSATIONS

If FKF is not efficient, the front knee buckles. This is seen in pitchers and hitters whose front knees (and front sides) drag past front foot strike and bend disproportionately to leverage loads. You cannot directly train FKF, as it is a byproduct of energy flow. Movement training is the only effective avenue to peak FKF.


ENERGY EFFICIENCIES

According to the physics Law of Energy Dissipation, energy cannot be destroyed, but will find the least path of resistence. Additionally, as in electrical engineering, energy must be downgraded or upgraded into usable form. Otherwise, it will cause breakage or injury. Evidence of such can be found in electrical transfer stations that downgrade energy from transformers to homes.


In baseball, FKF is used as a transfer station. If it is not efficient and proportionate to linear energy loads (created by the back hip drive), energy will flow into the ground or create the front knee to buckle under pressure.
