3.4. Sequential effect analysis
Further comparisons were made to determine if there were any order effects in the 2 experiments. In Group 1, the first experiment was the speed and accuracy test (X1), and the second experiment (cross-over) was the same test for the exercise group (X2). The difference was calculated as X = |X1 − X2|. In Group 2, the first experiment was the aiming response test for the exercise group (Y1), and the second experiment (cross-over) was the same test for the control group (Y2). The difference was calculated as Y = |Y1 − Y2|. The evaluation method for visual memory and reaction time tests was the same. The difference in results (X and Y) between Group 1 and Group 2 showed no statistically significant differences (Comparison of inter-individual differences in each index after 30 min of exercise.
