as .56, corresponding to a strong effect. According to post-hoc tests with investigations of adult neuroplasticity as an effect of long-term physical activity in old age 29
Bonferroni correction, there was a trend toward an increase in volume in the
left amygdala from posttest 1 to posttest 2 (p = .085). There were no signifi-
cant group differences. Furthermore, it was shown that BDNF concentration
in blood plasma remained stable over the five-year training period (F(3,45) =
2.591, p = .064, partial η² = .15). No significant group differences were present.

In addition, it was revealed that the Corrected Recognition Performance
in the VLMT was significantly improved over the five-year training period in
the sportive dance group (Chi-Square(3) = 12.197, p = .007, n = 8) and remained
stable in the fitness training group (Chi-Square(3) = 3.387, p = .336, n = 9). No
significant group differences were found.

Moreover, it was shown that the “reaction time” in the LoS was signifi-
cantly improved during the five-year training phase (F(3,42) = 6.379, p = .001,
partial η² = .31). Cohen’s effect size f is .67, representing a strong effect. There
were no significant group differences. The “speed of movement” in the LoS
was also significantly increased during the five-year training period (F(3,42) =
4.925, p = .005, partial η² = .26). Cohen’s effect size f was .59, reflecting a strong
effect. No significant group differences were observed. Furthermore, the “end-
point” in the LoS demonstrated a significant increase over the five-year train-
ing period (F(1.83, 25.58) = 9.221, p = .001, partial η² = .40). Cohen’s effect size f
was .81, indicating a strong effect. There were no significant group differences.
The “maximum deflection” in the LoS was also significantly enhanced (F(3,42)
= 12.476, p < .001, partial η² = .47). Cohen’s effect size f was .94, which corre-
sponded to a strong effect. No significant group differences were present.
