Measure
tDCS and Aerobic Exercise
Each participant will undergo a 20-minute session of transcranial direct current stimulation (tDCS) delivered to the dorsolateral prefrontal cortex (DLPFC). Each session of tDCS will be immediately followed by a supervised 30-minute, moderate-intensity bout of exercise. These procedures will occur 3x/week for 8 weeks. tDCS: Participants in transcranial direct current stimulation (tDCS) will receive tDCS over the dorsal-lateral prefrontal cortex for 20 minutes, 3 times per week for 8 weeks. Aerobic Exercise (AE): Participants will engage in supervised, 30-minute bouts of moderate-intensity exercise 3x/week for 8 weeks.
Sham tDCS and Aerobic Exercise
Each participant will undergo a 20-minute session of sham transcranial direct current stimulation (tDCS) delivered to the dorsolateral prefrontal cortex (DLPFC). Each session of tDCS will be immediately followed by a supervised 30-minute, moderate-intensity bout of exercise. These procedures will occur 3x/week for 8 weeks. Sham tDCS: Participants in sham transcranial direct current stimulation (tDCS) will receive shame tDCS over the dorsal-lateral prefrontal cortex for 20 minutes, 3 times per week for 8 weeks. Aerobic Exercise (AE): Participants will engage in supervised, 30-minute bouts of moderate-intensity exercise 3x/week for 8 weeks.

PRIMARY outcome

Timeframe: 8 week assessment

Population: The numbers analyzed include only individuals that provided valid wear-time data on the primary outcome measure, using accelerometry. Specifically, only participants that provided 3 days of 8 hours/day valid wear time were included in the analysis of the primary outcome.
