Effects of distinct aerobic trainings and taper-like periods on markers of O₂ transport capacity to tissues in recreational athletes. Mean ± standard deviation values of a hematocrit %, b circulating levels of hemoglobin (HB), and c mean corpuscular hemoglobin concentration (MCHC) of recreational athletes before (white bar), post 4 (gray bar, 4-w) or 8 weeks (black bar, 8-w) of distinct aerobic trainings. Groups: control (without training), undulatory-undulatory (Und-Und), undulatory-linear (Und-Lin), staggered-undulatory (Sta-Und), and staggered-linear (Sta-Lin). Δ, variation; d, effect size; *indicates p ≤ 0.05. Statistical bars indicate comparisons between distinct groups
