Primary outcome measures | ||||||
VLT | Verbal memory | Learning curve ratio | (Trial 1 + (Trial 2-Trial 1) + (Trial 3-Trial 2) + (Trial 4-Trial 3) + (Trial 5-Trial 4)) / 5 | 0–3 words per trial | Better learning capacity | 98% |
 | Mean number of recalled words trial 1–5 | (Trial 1 + Trial 2 + Trial 3 + Trial 4 + Trial 5) / 5 | 0–15 words | Better short-term verbal memory |  | |
 | Number of words recalled in delayed trial |  | 0–15 words | Better long-term verbal memory |  | |
TMT | Task switching | Time to complete part B minus time to complete A in sec |  | 0-∞ sec | Worse shifting capacity | 96% |
SST | Inhibition | SSRT in ms | The SSRT is estimated in accordance with De Jong et al. [42] and Tannock et al. [43]. Negative SSRT values are excluded from the analyses [44]. | 0–1500 ms | Worse inhibition | 90% |
LDST | Processing speed | Number of correct substitutions |  | 0–125 subs | Better processing speed | 96% |
Physical activity | ||||||
ActiGraph GT3X-BT | PA | MVPA minutes per week | Data downloaded with frequency extension on with ActiLife software [45]. Valid if worn 4 days during 10 h or more [46]. Non-wear definition by algorithm of Choi et al. [47]. PA scoring by Freedson-VM cut-off points [48] and by Aguilar-Fariaz cut-off points [49]. | 0–6720 min | More MVPA | 96% |
 | LPA minutes per week |  | 0–10,080 min | More LPA |  |
