  In a controlled trial, ten athletes were asked to over-train for three weeks. Blood samples were taken immediately before starting, at the end of the three weeks, and again three weeks after returning to normal. The researchers found steady declines in the percentage of CD4+ T-cells, with the lowest amount occuring 3 weeks after returning to a normal exercise schedule. The authors also found reductions in the CD4/CD8 ratio. Finally, the authors also checked levels before and 5 minutes after acute exercise, and again found reductions in CD4 percentages and in CD4/CD8 ratios.
