There needs to be a greater emphasis in training placed on improving eccentric strength.

The question is, how best can one achieve eccentric strength gains?

The prime directive in this case, is the rule of specificity.

I’ve found the best way to improve eccentric strength is by event specific application.

This is problematic in that an athlete will breakdown over time if all they do is full approach /max Intent bowling.

So if constant, max effort bowling is not the answer, then the next step would be to break down the event by segment and train for the requirements at BFC/FFC-SKILL STABILITY

This is where the conservation thru conversion of kinetic energy becomes the focal point.

The search for the best way to convert horizontal kinetic energy eliminates the use of “negatives” such as one would find in the weight room.

“…While these are essentially eccentric contractions, we must consider the overload principal in assessing the effectiveness of these exercises (negatives) 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”

“When comparisons between isometric, concentric and eccentric contractions were normalized to the mean force or time produced, eccentric contractions were found to be more variable. The findings of this study support previous results (Christou & Carlton, 1999) and suggest that eccentric contractions might be more variable due to an alternative recruitment of motor units, as 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, we are left with the following parameters in the search for optimal, eccentric 

1. Single-leg ground contacts

2. Shortest possible ground contact duration / Highest Rate of Force Development

3. Creation of “Super-Maximal” eccentric load/demand

Assess don’t guess
