In the present study, to determine the efficacy of oral supplementation of ginseng berry extracts in augmenting exercise performance and exercise-associated metabolism, male mice were given orally 200 and 400 milligrams per kilogram of body weight (mpk) of GBC for seven weeks. Although there are no differences in pre-exercise blood lactate levels among (1) the control group that received neither exercise nor GBC, (2) the group that performed only twice-weekly endurance exercise, and (3 and 4) the groups that combined twice-weekly endurance exercise with either 200 or 400 mpk GBC, statistically significant reductions in post-exercise blood lactate levels were observed in the groups that combined twice-weekly endurance exercise with oral administration of either 200 or 400 mpk GBC. Histological analysis showed no muscle hypertrophy, but transcriptome analysis revealed changes in gene sets related to lactate metabolism and mitochondrial function. GBC intake increased nicotinamide adenine dinucleotide levels in the gastrocnemius, possibly enhancing the mitochondrial electron transport system and lactate metabolism. Further molecular mechanisms are needed to confirm this hypothesis.
