It was observed that wearing the "Powerunit" stabilized the body core and made it possible for runners to run more effectively and fast. Shoulder blades also moved efficiently, which made the mobility of the pelvis better, and as a result runners were able to fling legs further forward. Even with high speed the form was not much disturbed.

It was observed that maximum oxygen consumption (VO2 max) was increased when the "Powerunit" was worn.
