Effects of Short-Term Physical Activity Interventions on Simple and Choice Response Times

Table 1

Descriptive data for the subjects. Physical activity (PA) data are total median (mean ± SD) minutes per week using REMM analysis. There were two participants from the group intervention arm who had missing preintervention RT data.
