From: Alterations in the innate immune system due to exhausting exercise in intensively trained rats

Effect of exercise training on the spleen NK cell proportion (A) and the spleen NK cytotoxic individual activity (B). SED = sedentary rats, S-TE = rats with a short intensive training and a final exhaustion test, T = trained rats, TE = T rats with an additional exhaustion test, and TE24 = TE rats 24 h after the final exhaustion test. Data are expressed as mean ± SEM (n = 6–12). Values not sharing letters denote significant differences (p < 0.05) (Mann–Whitney U test).
