No 2 bowlers will land on the back foot the same.

 

The quality of the contact can have a massive impact on the quality of the full ‘Kino-sequence’ of fast bowling.

 

Based on bowling type Ground contact times of 0.112 on BFC for a hip DOMINANT bowler and 0.502 for a KNEE DOMINANT bowler confirms my belief that bowling type dictates how they should be trained.

 

The amortization phase (coupling time) of the back-foot contact is critical to successful fast bowling and that the strength needed most by the bowler is not for extension/pushing off but for the prevention of excessive flexion at the plant.

 

This is a function of eccentric strength.

 

However, understanding whether knee flexion occurs due to an ingrained motor pattern/habit or a lack of strength is really important.

 

Some have a large knee flexion due their dominance- they are knee dominant and more often than not out squat everyone.

 

They love the ‘bend in the knee’.

 

Allows them to create more time and allows them to utilise the longer SSC.

 

So over squatting a knee dominant bowler would actually be detrimental.

 

Increasing the strength deficit would interfere with the timing and the ‘quickness’ of the back foot.

 

Some knee dominant bowlers , despite massive squat numbers may infact look weak on BFC as they sink further to increase time and therefore increasing the time on BFC and losing GRF.

 

They don’t utilise the ‘spring mass model’ effect on BFC.

 

While heavy-resistance strength training ultimately produces a greater maximum force, the greater force production comes at a cost in time of application.

 

Rate of Force Development (RFD) is of prime importance in the efficient conversion of horizontal kinetic energy to vertical impulse.

 

Although some mechanics and angles may differ on BFC (HIP OR KNEE) it’s about the conversion and / or conservation of energy at BFC.

 

While all bowlers will lose energy, the vertical velocity at ground release from BFC into FFC is a determining or limiting factor in the maximum height that the bowlers centre of mass (CM) will reach during the delivery.

 

Matching up a bowlers biomotor strengths with their current bowling type can have a massive impact in their success and career.

 

Assess don’t guess
