Dileucine and Resistance Training Adaptations — DTS  

Hypertrophy Clinical Trial

Official title:
A Pilot Study to Examine Changes in Resistance Training Adaptations After Leucine and Dileucine Ingestion

Clinical Trial Summary

This study seeks to compare the observed changes in resistance training adaptations after supplementation of isomolar amounts of leucine or dileucine in healthy resistance-trained men. This will provide a better understanding of supplementation with leucine versus dileucine over a 10-week period in regards to increasing muscular performance.

Clinical Trial Description

The study will be conducted using a randomized, double-blind approach with individuals being provided daily 2-gram doses of leucine, 2-gram doses of dileucine, or a placebo. Daily blinded supplementation will occur each day for a 10-week period of time while completing a heavy resistance training program. Participants follow the resistance training program for a total of 10 weeks. To compare the efficacy of leucine in form of amino acid or dipeptide supplementation on resistance training adaptations, changes in fat-free, lean, and fat mass will be determined using a 4-compartment body composition model. Skeletal muscle cross-sectional area will be assessed using ultrasound. Maximal strength, muscular endurance, and power will also be assessed. Participants will be required to provide weekly compliance and complete one supervised workout per week. After 2, 6, and 10 weeks of following the supplementation and resistance training regimens, participants will return to the laboratory to complete testing bouts consisting of identical assessments of body composition, muscular strength, muscular endurance, lower-body power, and anaerobic capacity. Adverse events related to each supplementation group will be recorded and assessed. ;
