Imaging data from two football athlete subjects showing a comparison between abnormal voxels from the season with the higher 50th percentile number of impacts per practice session and abnormal voxels from the season with the lower 50th percentile
number of impacts per practice session. The season with the lower impact frequency in practice sessions was associated with fewer abnormal voxels compared to the season with a higher impact frequency in practice sessions for both athletes.
