​

Purpose: To test the hypotheses that jumping, sprinting, and change-of-direction speeds (CODS) represent separate and specific motor abilities, and that the jumping ability based on concentric and slow stretch-shortening cycle (SSC) is relatively independent of the same ability based on fast SSC.

​

Conclusions: These results supported our hypotheses regarding the specificity of jumping, sprinting, and CODS abilities, and specificity of the concentric/slow SSC and fast SSC jumping abilities.

​

IN PLAIN ENGLISH: Specificity. It is all about EXACTNESS.
