About

The purpose of this randomized, double-blind, crossover study is to investigate the effects of Bang® Keto Coffee on resting and post-exercise metabolism and muscular performance during lower body resistance exercise.

Full description

Resistance-trained males and females will be recruited for participation in a randomized, double-bind, crossover trial. After providing informed consent, each participant will undergo a familiarization session to become accustomed to the study procedures. Following familiarization, each participant will complete two laboratory visits consisting of metabolism and exercise performance assessments. In both visits, a baseline assessment of resting metabolic rate (RMR) and respiratory exchange ratio (RER) will be conducted using indirect calorimetry. Following the initial RMR assessment, each participant will ingest a coffee flavored beverage, either VPX Bang® Keto Coffee or a flavor-matched placebo. After beverage consumption, the participant will return to the supine position and rest prior to initiation of the second RMR assessment. Immediately following the second RMR assessment, the participant will begin a 5-minute dynamic bodyweight warm up. Participants will then begin squat testing procedures on a mechanized squat device. After completing the squat testing, participants will complete a standard 1-repetition maximum and repetitions to failure using a plate-loaded hip sled machine. Following the hip sled testing, participants will repeat the mechanized squat testing. Following completion of the exercise testing, a third and final RMR assessment will be performed. Following successful completion of the first condition, each participant will enter a wash out period, after which the visit will be repeated with ingestion of the alternative beverage.

Volunteers

Accepts Healthy Volunteers

Inclusion criteria

Between the ages of 18 and 40
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 supplement of performance of exercise, including but not limited to musculoskeletal or cardiovascular diseases).
Resistance-trained, defined as completing 3+ resistance training sessions per week for at least one year and including at least weekly training of the lower body through a multi-joint exercise such as the squat or leg press.
Regular caffeine consumption, defined as an average self-reported daily intake of 200+ mg of caffeine, which is equivalent to approximately 2 cups of coffee.

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 lower body resistance exercise due to injury or medical condition
Self-reported caffeine sensitivity, as indicated by unwanted side effects when caffeine is consumed.
Allergy to any of the ingredients in the commercially available dietary supplement
Self-reported claustrophobia (due to metabolism testing)
