For this study, 11\u00a0352 participations, belonging to 1085 horses grouped by age (4\u2010, 5\u2010 or 6\u2010year olds), were analysed. repeatability animal models (\n                    <jats:styled-content style=\"fixed-case\">RAM<\/jats:styled-content>\n                    ) and multiple trait animal models (\n                    <jats:styled-content style=\"fixed-case\">MTAM<\/jats:styled-content>\n                    ) were compared.\n                    <jats:styled-content style=\"fixed-case\">RAM<\/jats:styled-content>\n                    assumed the same covariance components for all age groups, whereas\n                    <jats:styled-content style=\"fixed-case\">MTAM<\/jats:styled-content>\n                    considered the results of every animal at every age group as different (but correlated) traits. The age, sex, starting order and training level were included as fixed effects. The random effects were the animal, the individual permanent environment, the competition and the rider. Six models were compared, and the rider\u2013horse interaction was added as a random effect; furthermore, heterogeneous residual variance was taken into consideration only for\n                    <jats:styled-content style=\"fixed-case\">MTAM<\/jats:styled-content>\n                    .
