Figure 3

Blood sampling protocol (A) and acute BDNF changes in response to the interventions in serum (B) and in plasma. (C) BDNF concentrations in serum increase in response to physical exercise (sample 1 to 2 in PE and PE + COG groups; sample 2 to 3 in COG + PE group) but not in response to cognitive training (sample 1 to 2 in COG and COG + PE; sample 2 to 3 in PE + COG group). BDNF concentrations in plasma increase independent of intervention. Note that the hypothesis testing involved specific group comparisons and merging of groups. PE = physical exercise, COG = cognitive training.
