They caution that additional research is needed to track changes in fitness and brain structure over time, as well as clarify the impact of specific exercise programs (such as strength, aerobic or combined training) or dose of exercise (frequency, intensity, duration) on white matter microstructure.

Selective effects of aging on brain white matter microstructure: A diffusion tensor imaging tractography study (semanticscholar.org)
A new study led by University of North Carolina School of Medicine researchers concluded that patterns of white matter microstructure present at birth and that develop after birth predict the cognitive function of children at ages 1 and 2. (brightsurf.com)
