Performance in most sports is not determined by maximum strength, but rather by the speed of the application of strength with environmental resistance. This leads us to the concept of explosive strength. Explosive strength refers to the ability of a muscle to build work tensions rapidly at the beginning of the performance, and to increase them in the course of the performance.
The explosive effect is guaranteed by the sequential expression of the following subtypes of strength:
1) The absolute speed of muscle contractions (V)
2) Starting strength (Q)
3) Acceleration strength (G)
4) Maximum strength (P)
These components are developing independently; progress in one has little effect on the other. The farther apart they are, the smaller their mutual influence (the smallest, therefore, between V and P). Based on this, it is evident that the last contributor to vertical jumping ability is maximum strength. The main relevance is on how fast can you apply your muscles, and how great is their elasticity.
The application of each component demands a specific movement regimen that affects (trains) only one of them, and has little to no effect on the others. As mastery increases, the relative independence of these components increases as well. Training them requires differentiated efforts: P and G are easier to perfect than V and Q.
