Treg/(NK + Tδγ + CTL) ratio (a), Treg/NK ratio (b), Treg/Tδγ ratio (c) and Treg/CTL (d) ratio during exercise tests performed prior to and after supplementation with LTE (mean ± SD). Note. Tregs = regulatory T cells; NK = natural killer cells; Tδγ = gamma delta T cells; CTL = cytotoxic T lymphocytes; □ − SUPPL = supplemented group; ● − PLA = placebo group; B = baseline; Ex = post-exercise; R = after a 1-day recovery; # - significantly different compared to baseline level; * - significantly different compared to post-exercise level
