Ginseng Does Not Benefit Exercise Recovery


Ginseng Does Not Benefit Exercise Recovery

DETROIT--Researchers from Wayne State University reported ginseng supplementation may not improve either immune function or performance after repeated bouts of strenuous exertion. In a double blind, placebo-controlled, randomized study published in the April Medicine & Science in Sports & Exercise (55, 4:690-696, 2003) (www.ms-se.com), 27 active, healthy adults were given either placebo or a standardized ginseng concentrate (400 mg/d of G115, equivalent to 2 g of Panax ginseng C.A. Meyer root) for eight weeks. Before and after intervention, subjects performed three consecutive 30-second cycling tests.

The researchers found secretory immunoglobulin A secretion rate (a marker in immunity) was lower after exercise than at baseline. In addition, supplementation failed to improve physical performance or heart rate recovery after exercise.
