Jump Height and Absolute Strength: An Indirect Relationship

[email-subscribers namefield=”YES” desc=”” group=”Public”]

 

One of the most commonly talked about topics in strength and conditioning is the role that maximal strength plays in performance and whether or not it is necessary.

Before I dive into this topic, let me get some of the confusion out of the way. Maximal strength is not only important for performance, but it is mandatory. Without some level of maximal strength, there is no way any effort of great power could ever be performed.

Explosive Strength Development

Explosive strength is not an independent quality, meaning there is no specific exercise that directly trains all of the components involved in its production. Instead, it is comprised up of four “elementary qualities” (listed below and in figure 1). These elementary qualities are independent of each other and must be developed through separate means. Together, they form the expression of explosive strength.

 

  1. Maximal Velocity (Vo)
  2. Starting Strength (early stage rate of force development) (SS)
  3. Acceleration Strength (late stage rate of force development) (AS)
  4. Maximal Strength (So)
