• 1 other identifier: IRB-19-L0043
• Study Type: interventional
• Target: 24
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to compare the ability of isocaloric and isonitrogenous (2 x 15-gram) doses of rice protein or whey protein to stimulate resistance training adaptations in young, healthy, resistance-trained men.

Outcome Measures

Primary Outcomes (2)

• Changes in upper- and lower-body strength via Dual-Energy X-ray Absorptiometry

  Examining how much strength each participant gains (or loses) from Day 1 to Final day

  Eight weeks

• Changes in fat-free mass via Dual-Energy X-ray Absorptiometry

  Examining the differences in fat-free mass from Day 1 to Final day

  Eight weeks

Secondary Outcomes (2)

• Changes in muscular endurance by counting repetitions for each exercise test

  Eight weeks

• Changes in resistance training volume by tracking how many pounds were lifted during each exercise

  Eight weeks

Eligibility Criteria

• Age: 18 Years - 50 Years
• Sex: male
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Between the ages of 18-50 years, although it is anticipated that the majority of participants will be between 18 and 35 years of age.
• Participants will be healthy and free of disease as determined by evaluation of a medical history
• All participants will be required to abstain from taking any additional forms of nutritional supplementation (preworkouts, creatine, beta-alanine, etc.) for four weeks prior to beginning this study and for the entire duration of the study.

You may not qualify if:

• Those individuals with less than 12 months of structured resistance training experience will be excluded from the study.
• Individuals whose maximal relative upper body strength is below 1.0 will be excluded.
• Individuals whose maximal relative lower body strength is below 1.50 will be excluded.
• As indicated on a medical history form they complete, any individual who is currently being treated for or diagnosed with a cardiac, respiratory, circulatory, musculoskeletal, metabolic, obesity (defined as body mass index \> 30 kg/m2 and body fat greater than 30%), immune, autoimmune, psychiatric, hematological, neurological or endocrinological disorder or disease will be excluded.
• Those individuals who present with any previous injury or illness that would prevent them from appropriately completing all exercise lifts will be excluded from the study.
• Participants who are not able to fit onto the DEXA table will not be able to participate in the research due to size restrictions of the equipment. This typically includes individuals exceeding 300 pounds or those greater than 6 feet 6 inches.
• Those individuals less than 18 and greater than 50 years of age will be excluded. Participants younger than 18 are excluded due to necessity of parental consent. Participants greater than 50 years old lie outside of the target demographic for the current study.
• Participants who are determined to not be weight stable defined as week 0 and week 2 body mass levels deviating by 2% or more.

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: DOUBLE
• Who Masked: PARTICIPANT, INVESTIGATOR
• Masking Details: The supplements were delivered in identical containers with rather an "A" or "B" marked on the outside of the bag. Once data collection, data entry, and statistical analysis was completely finished, the study code was broken.
