The "winning edge" was tested on fifty athletes* who were divided into two groups, a control group and a group that added Chiropractic care to their usual training procedures.
After six weeks, the group getting Chiropractic care scored significantly better on standard tests of athletic ability. When tested, the control group (not getting care) demonstrated less than one percent improvement their reaction time.
The Chiropractic group achieved reaction times of more than eighteen percent faster than their initial scores
