Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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 Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type EXPERIMENTAL

Cycling Exercise

Intervention Type BEHAVIORAL

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.

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.

Group Type EXPERIMENTAL

Cycling Exercise

Intervention Type BEHAVIORAL

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.

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.
