*Calculated from ‘athletic exposure’ (one athletic exposure=2 exposure hours).
†Total exposure hour includes activities performed outside training/matches; therefore, exposure hours in training and matches will not sum to total exposure hours^.
‡Data reported on training and matches hours of exposure do not sum to total exposure hours.
NR, not reported.
