The purpose of this study was to analyse the intake of leucine as a determinant of muscle strength and gait speed in the elderly. This research is a cross-sectional study that involved 132 elderly people in the community (34 men and 98 women), aged 60–69 years. Data were obtained from interviews, physical examinations (body weight, body height, muscle mass, muscle strength, and gait speed), as well as food recall 3x24 hours. The statistical analysis employed Pearson’s correlation coefficient and multiple linear regression. Intake of leucine was positively correlated with muscle strength (r=0.3; p<0.001) and gait speed (r=0.244; p<0.05). It was not inta
