Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 26
Sex Male
Age Range 18-29

Notes for this study:
4g (based on 50mg/kg) leucine daily to untrained men participating in a resistance training protocol was able to enhance the increase in power output from 31.0% to 40.8% without affecting the rate of lean mass or fat mass changes. Diet was not controlled in this study, but protein reported to be 0.88-0.90g/kg and no significant differences between groups.
