Stiffness is often viewed as limited or decreased flexibility, particularly in the joints and muscles. While this type of stiffness is a reality, if we think of stiffness in simple physics terms, it is the extent to which a structure resists deformation in response to an applied force. That second definition is the one we are most concerned with when…
Stiffness is a word that has several definitions. It’s poorly understood among some in the athletic and fitness community. However, most coaches and conditioning specialists understand the value of athletic stiffness. That’s what PK & I discuss today. We define stiffness and introduce some simple physics to help you gain an appreciation for the quality that is crucial for the…
