Outcome Measures

Primary Outcomes (1)

  • Maximum strength of knee extensor muscles

    Strength testing will be repeated every two weeks for 12 weeks

    12 weeks

Secondary Outcomes (1)

  • Fat-free mass

    12 weeks

Study Arms (2)

Not essential amino acid

SHAM COMPARATOR

Non essential amino acid: The subjects will have a regimen of high-intensity progressive resistance training of the knee extensors 3 days per week for 12 weeks. The subjects will receive 1 unit of an equivalent quantity of nonessential amino acids (alanine, aspartate, glycine, serine, histidine and proline in equimolar quantity) isonitrogenous to 10 g of citrulline, once in the morning for 12 weeks.

Dietary Supplement: Non essential amino acid

Citrulline

EXPERIMENTAL

The subjects will have a regimen of high-intensity progressive resistance training of the knee extensors 3 days per week for 12 weeks. The subjects will receive citrulline 10 g/day orally in the morning for 12 weeks.

Dietary Supplement: Citrulline

Interventions
