ABSORPTION OF ENERGY
All movement activity generates energy. Energy directly returned to the body can result in shin splints, back and knee problems, fatigue, strains, and even broken bones. A non-energy absorbent floor or flooring system is dangerous. It can result in injury and law suits. Concrete is non-energy absorbent. Any substance put directly on concrete does not remove you from the concrete unless it contains air (like foam). Basket weave and foam sprung floating subfloors provide shock absorbent characteristics that eliminate the problems associated with hard, non-absorbent floors.
No floor can be the most absorbent and the most resilient at the same time. There is only so much energy and it can only be diffused in varying relationships of absorption and resilience. We call that "feel" and it affects performance. Different surfaces and subfloors have different "feels," each appropriate for different activities.
LATERAL FOOT SUPPORT
Perhaps the most important and most overlooked attribute of a floor is lateral foot support. Without lateral foot support, you can not maintain balance. Today, the leading cause of injury is not shin splints but ankle injury, due in part to flooring systems that rely solely on absorbent materials or systems that are too spongy.
A term you may come across is point elastic, meaning deflection of the floor at the point of impact. The greater the deflection, the more unstable the floor.
In addition to absorbency, energy can be dissipated by resiliency-think of a diving board or trampoline. Energy transfers from the body to a subfloor that deflects and safely returns energy (spring). Wood is the best of the resilient materials.

Safety is the number one issue when it comes to floors. The first safety concern is the non-slip characteristic of the surface. What to do?
Aerobic, step, and jazzercise need one kind of surface while people working with weights and machines need something entirely different. Multi-purpose, track, and ball sports have their own ideal characteristics.
Aeson has floors and subfloor systems ideal for each discipline.
Safety and Shock Absorbency
The second safety concern has to do with the ability of the floor to absorb and dissipate energy, and/or safely return energy (resilient energy). If the floor fails to absorb or safely return energy, the body becomes the shock absorber, resulting in fatigue, pain, and injury. The nemesis of physical fitness is concrete or any other surface that is hard and unyielding.
All floor surfaces without foam underlayment provide no relief from a concrete slab. Check the flooring charts on page 5 for relative characteristics and the ideal combination for your movement activity.
