Maximal power output and peak oxygen consumption. Evolution of the maximal power output (Pmax, a) and peak oxygen consumption (VO 2 peak, b) before and after each of the three test series in the placebo and donation group. Data are expressed as means ± SEM. n = 7 in placebo and n = 13 in donation for test series 1; n = 5 in placebo and n = 13 in donation for test series 2 and 3. ### p < 0.001 vs. -1w of test series 1, same group. *p < 0.05, ***p < 0.001 vs. -1w of the same test series, same group. Symbols are placed above the curves for the placebo group and under the curves for the donation group
