The mechanism of calena’s "supporting power"

The Support Theory
The Support Theory

The surface of the back expands when bending forward. “calena” turns this force into tensile strength of its elastic fabric, reducing the muscle load. Additionally, the elastic fabric is loose and free of tension when one is standing upright, so there is no tight sensation to the wearer.

A Power-net Structure that Sustains the Supporting Power
A Power-net Structure that Sustains the Supporting Power

The special power-net structure balances out and disperses the supporting power that is transmitted down the back throughout the pelvis area, with a focus on the ischial bones. This results in no unwanted pressure and wedging in the bottom areas.

Evidence of Reduced Load Effects
Evidence of Reduced Load Effects

Results confirming that there was a 10% reduction of muscle stress in the back area were found in experiments having the subject bend down and maintain a 40 degree angle.
