Study summary

This project investigates the effects of a bicycling exercise at three levels of exercise intensity (low, moderate, and high) on attention deficit/hyperactivity disorder (ADHD) in college students. Specifically, the outcomes of interest in this study are self-reported executive functioning, self-reported functional impairment, and ADHD symptom severity. The hypothesis is that exercise will improve executive functioning, while reducing functional impairment and ADHD symptom severity, and that this response will be most pronounced in the high-intensity exercise group.

Study arms

  • Experimental
    Low Intensity

    The low intensity arm will perform 20 minutes of steady-state cycling on an airdyne bike. Intensity will be confirmed with continuous heart rate measurement, and heart rate should not exceed 65% of maximal heart rate (220-age) in this arm.

    Behavioral: Cycling Exercise

  • Experimental
    Moderate Intensity

    The moderate intensity arm will perform 20 minutes of steady-state cycling on an airdyne bike, maintaining heart rate between 65-85% of maximal heart rate.

    Behavioral: Cycling Exercise

  • Experimental
    High-Intensity

    The high-intensity arm will perform a 3-minute steady-state cycling warm up on an airdyne bike, followed by 16 minutes of high intensity interval training (HIIT) cycling. The HIIT protocol consists of alternating periods of 20 seconds of high-intensity effort and 120 seconds of return to low-intensity steady-state cycling. The heart rate goal to ensure high-intensity effort is to maintain heart rate \> 85% maximal heart rate during the 20 second high-intensity bursts.

    Behavioral: Cycling Exercise

Interventions

  • BehavioralCycling Exercise

    Each arm will perform a 20-minute cycling intervention on an airdyne bike at different exercise intensity levels. Participants will perform the intervention three times over the course of one week.

What researchers measure

Primary outcomes

  1. Self-Reported Executive Function

    Self-reported executive function will be measured using a modified version of the Barkley Executive Function Scale (BDEFS)

    Time frame: The BDEFS will be assessed on the first day of participation in an exercise intervention (session 1) and again on the last day of the intervention (session 3). Session 1 occurs on a Monday, session 2 on a Wednesday, and Session 3 on a Friday.

  2. Self-Reported Functional Impairment

    Self-Reported Functional Impairment will be measured using a modified version of the Barkley Functional Impairment Scale (BFIS)

    Time frame: The BFIS will be assessed on the first day of participation in an exercise intervention (session 1) and again on the last day of the intervention (session 3). Session 1 occurs on a Monday, session 2 on a Wednesday, and Session 3 on a Friday.

  3. Self-Reported ADHD Symptom Severity

    Self-Reported ADHD Symptom Severity will be measured using the Barkley Adult ADHD Rating Scale IV (BAARS-IV)

    Time frame: The BAARS-IV will be assessed on the first day of participation in an exercise intervention (session 1) and again on the last day of the intervention (session 3). Session 1 occurs on a Monday, session 2 on a Wednesday, and Session 3 on a Friday.
