Figure 1: Normalised data for placebo and TE group across after 90 minutes exercise. In the TE group, statistically significant improvements were observed (ANOVA) in both co-normalised detection score and detection time at this time point (* denotes P<0.05). Normalised identification scores and speeds trended toward significance († denotes P<0.1), whereas no effect was observed for normalised one card learning scores and speeds

Figure 2: Relationship between score achieved and response time plotted as a percentage of placebo. The ratio score to speed is significantly higher (ANOVA) at 90 minutes for detection (P=0.03) i.e. a higher score was achieved in a faster time. A similar phenomenon was observed for the identification test, which trended towards significance (P=0.1) test
