Changes of T cell phenotypes during the exhaustive submaximal endurance and resistance exercises. (A) CD4(+) and CD8(+) T cell populations in peripheral blood lymphocytes at rest, and 0 and 30 min after the submaximal endurance exercises. (B) CD4(+) and CD8(+) T cell populations in peripheral blood lymphocytes at rest, and 0 and 30 min after the submaximal resistance exercises. (C) CD4:CD8 ratio at rest, and 0 and 30 min after the submaximal endurance and resistance exercises. * represents statistical significance between “rest” and “end” (P<0.05). ** represents statistical significance between “rest” and “end” (P<0.01). # represents statistical significance between “end” and “recovery” (P<0.01). CD4(+): CD4 positive helper T cells. CD8(+): CD8 positive cytotoxic T cells. CD4:CD8 ratio: the ratio of CD4 (+) to CD8(+). 85% VO₂max: 85% of maximal oxygen consumption. 85% 1-RM: 85% of one repetition maximum. Recovery: time point at 30 min after each exercise.
