Study type | Interventional |
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.

Eligibility | 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 eligible or this study. Exclusion Criteria: - Failing to meet any of the aforementioned inclusion criteria. - Pregnant or breastfeeding (for female participants) - Taking prescription medication which could reasonably make participation unsafe for the participant or influence study outcomes - An inability to complete resistance exercise due to injury or medical condition - Inability to complete a 16 hour fast. - Allergy to any of the ingredients in the provided breakfast and lunch. - Current use of anabolic steroids - Presence of a pacemaker or other implanted electrical device. - Inability to perform the exercises with safe and proper form as determined by members of the research team. |
