The Effect of Breakfast Consumption on Afternoon Resistance Training Performance
United States39 participantsStarted 2021-11-17
Plain-language summary
This study is a randomized crossover trail examining the effect of breakfast consumption or omission on afternoon resistance training performance. Resistance-trained adults will complete a resistance training workout comprised of barbell back squat, barbell bench press, and barbell conventional deadlift following either consuming breakfast and lunch, or the same amount of food consumed solely at lunch. For each testing session the participants will be provided with all food to consume prior to arriving at the laboratory. Major performance outcomes will be total repetition volume completed for each exercise (i.e. bench press, squat, and deadlift) and the entire workout (each individual trial), along with barbell kinematics for each exercise.

Inclusion Criteria:
* Between the ages of 18 and 40
* Body mass between 50 - 110 kg (110-242 lb)
* Generally healthy (defined as an absence of any disease or medical condition which could potentially be negatively affected by consumption of the commercially available dietary supplements or performance of exercise, including but not limited to musculoskeletal or cardiovascular diseases).
* Resistance-trained, defined as completing 2+ resistance training sessions per week for at least three months prior to screening.
* Participants must self-report either consuming or skipping breakfast ≥ 5 times per week for three months prior to screening.
* Participants must have reported regular training of the lower body through a multi-joint exercise such as the squat or leg press at least once weekly during the three-month period prior to screening.
* Participants must have reported regular training of the bench press or chest press variation at least once weekly during the three-month period prior to screening.
* Participants must have reported regular training of the deadlift or deadlift variation at least once weekly during the three-month period prior to screening.
* Female participants will be required to bench press ≥ 0.5 x body mass, barbell back squat ≥ 0.75 x body mass, and deadlift ≥ 1.0 x body mass to be eligible or this study.
* Male participants will be required to bench press ≥ 1.0 x body mass, barbell back squat ≥ 1.375 x body mass, and deadlift ≥ 1.75 x body mass to be e…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
