No results posted yet for this study

Summary

Our objective is to determine the dietary requirement of protein for strength and endurance exercise trained (more than 4 months training experience) individuals between 18 - 30 years of age using the indicator amino acid oxidation (IAO) method. This study will be the first to determine the required quantity of protein need per day in strength- and endurance trained young adults using the IAO method.

Measuring protein requirement

a repeated measures design will be used on each athlete receiving eight graded intakes of protein on separate days in the form of AA in random order ranging from 0.2 to 3.5 g/(kg/d). Three baseline samples of breath and urine will be collected at 60, 45 and 30 min before the stable isotope is given orally. During a period of 150 to 270 min. after stable isotope ingestion, 5 breath and urine samples (every 30 min) will be collected to determine an isotopic plateau in breath and urine. The rate of release of 13CO2 from the oxidation of L-\[1-13C\] phenylalanine (F 13CO2) in breath will be measured and a breakpoint analysis will determine total protein requirement
