In fitness spaces, high-impact activities such as weightlifting and plyometric exercises often result in heavy weight drops that exert significant forces on the floor. The measurement of these impacts is crucial for determining the durability, safety, and acoustic performance of fitness flooring. Effective flooring should extend the impact force impulse over time. Measuring the contact time of the impactor with the finish material and peak force exhibited by the acting force are measurable dynamic properties of a locally reactive material. Fitness floors cannot be excessively soft under human or equipment loading to provide a safe and effective surface for users. A static deflection measurement can be used to determine the perceived "softness" of the floor finish material. An analysis is conducted to determine the relationship, if any, between dynamic localized reaction (contact time) and static deflection of surfacing materials. Single number metrics are propsed to quantify the efficacy of locally reactive floors.
