I believe the greatest emphasis in training for quicks need to be placed on improving eccentric strength.
However, what is the best method to achieve eccentric strength gains?
The prime objective in any of my progs is the rule of specificity.
I would suggest that the best way to improve specific strength is by sport specific application.
This is problematic in that a bowler will breakdown over time if all they do is full approach /max effort bowl.
Forces are too great for repetition.
Full intensity bowl is not the answer, which is why the action is broken down into segment (SDE) and train for the requirements at BFC. SKILL STABILITY PARADIGM.
I’m of the opinion that the best way to convert horizontal kinetic energy may not be the type of eccentric training you find in the weight room.
I use TRIPHASIC STRENGTH to train the basic lifts which support specific eccentric overload but Improve the capacity to absorb force indirectly.
So in effect everything is essential but understand why you are doing something.
While ‘negatives’ are essentially eccentric contractions, we must consider the overload principal in assessing the effectiveness of these exercises in developing sport specific strength.
Much higher intensities than found in typical negative-type exercises may be needed to adequately overload the eccentric contraction mechanism to the extent required for the intensities found in fast bowling “A study by (Christou & Carlton, 1999) suggests that eccentric contractions might be more variable due to an alternative recruitment of motor units, as also suggested by Nardone et al. (1989).
The results of this study, provide further evidence to the hypothesis that eccentric contractions might be uniquely controlled by the CNS (Enoka, 1996)”
To provide specific overload; both event-specific and to challenge the “uniqueness” of eccentric contractions, I split my fast bowling eccentric training in the following groupings;
1. Single-leg ground contacts
2. Shortest possible ground contact duration / Highest Rate of Force Development
3. Creation of “Super-Maximal” eccentric load/demand
4. Nearest approximation of event specifics in the exercise performance
Assess don’t guess
