FITLIGHT Reliability and Acute Training Effects

Participants will receive the intervention in person once within in the study for 30 minutes. During the intervention, participants will receive a cognitive training session consisting of an upper extremity, lower extremity, and whole-body reaction time task. The device (5 LED) will be placed in front of participants in all tasks, and participants will be asked to deactivate lights that illuminate for a period of 30 seconds with 30 seconds of rest. For the upper and lower extremity tasks, these will be repeated on both limbs. The purpose of the tasks are to pre-train reaction time in an isolated fashion, requiring participants to use either hands or feet to deactivate the lights, as well as incorporate whole-body movement in the third task along with a decision-making (color-matching) component.

Participants will receive the intervention in person once within the study for 30 minutes. During the intervention, participants will watch, while seated, a 30-minute segment of a nature documentary. The purpose of this intervention is to ensure no additional cognitive or movement training that would improve performance on the dual-task test occurs during the intended rest period.
