FITLIGHT Reliability and Acute Training Effects

September 6, 2025 updated by: Zachary Ripic, University of Miami

Reliability of the FITLIGHT System and Acute Effects of Cognitive Training on Dual-task Performance in Hopping and Cutting Assessments

The purpose of this study is to assess the reliability of outcomes collected using a speed and cognitive light training system. This study will also be used to understand the effects of brain training on athletic performance using the FITLIGHT System.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Acute Cognitive Training Followed by Non-stimulating Rest Group
Participants will be in this group for approximately 11-14 days
Device: Acute Cognitive Training
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.
Other Names:
  • FITLIGHT
Other: Non-stimulating Rest
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.
