Study Details

Study Description

Brief Summary

Protein requirements in active individuals have been suggested to be greater than the current recommended dietary allowance (RDA).

Nutritional requirements for dietary amino acids in adolescents have traditionally been determined utilizing the nitrogen balance technique, which is prone to underestimating protein requirements. As a result, there is a need to re-evaluate recommendations in order to characterize how dietary amino acid needs may be modulated by physical activity.

Recent studies using the minimally invasive indicator amino acid oxidation (IAAO) technique have suggested that protein requirements in young men are at least 50% higher than the RDA based on nitrogen balance data.

The purpose of this study is to measure the protein requirement in adolescent, males using the IAAO technique in the presence of a variable intensity exercise stimulus.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Active, Adolescent males

Subjects will receive different levels of amino acid intakes, varying from 0.2-2.67 g/kg/d

Dietary Supplement: Amino Acid Intake
Amino acid intakes will be varied at 0.2-2.67 g/kg/d

Outcome Measures

Primary Outcome Measures

  1. 13CO2 ([13]Carbon Dioxide) Excretion (µmol/kg/h) [4 hours per study day]

    Each trial day will assess a different protein intake with 13CO2 excretion defining the level of protein adequacy. Each trial day will be separated by ~1wk washout with all trial being completed in approximately 3 months.

Secondary Outcome Measures

  1. [13C]Phenylalanine Oxidation (µmol/kg/h) [4 hours per study day]

    Each trial day will assess a different protein intake with 13CO2 excretion defining the level phenylalanine oxidation being used as a secondary marker of protein adequacy. Each trial day will be separated by ~1wk washout with all trial being completed in approximately 3 months.
