Influence of Chlorella powder intake during swimming stress in mice.

We used the forced swimming test to investigate the influence of Chlorella powder intake during muscle stress training in mice. After day 14, swimming time was about 2-fold longer for Chlorella intake mice than for control swimming mice. Microarray analysis revealed that the global gene expression profile of muscle from the Chlorella intake mice was similar to that of muscle from the intact (non-swimming) mice, and the profile of these two groups differed from that of the control (swimming) mice.
