ABSTRACT The objective of this study was to evaluate the effect of the trainer and the adopted daily work on the behavior and performance of horses of the Mangalarga Marchador breed on a horse farm and in racetracks in northern Minas Gerais State, Brazil. Twenty equines and nine trainers from four farms and three competition events of the breed were observed. The experiment was divided into two stages. In the first stage, the animals were observed together with their trainer on the farm, during the daily work, and the behavior reactions were recorded based on scores. The duration of training and the behavior told by the trainer of the animal were recorded in scores. The second stage happened in three competitions of the breed in agricultural fairs. The same observations were made on horse farms, including the behavior of the animal, before and after the trial, as well as the emotional state in the same period. For data analysis, multivariate statistics were used based on the principal components and factor analysis, using the statistical software R (version 3.3.2). From the data analyzed, it was verified that the variables embouchure, behavior and voice of the presenter, and reward and incentive in the competition influenced the reactivity of the animal. Variables of human behavior in training influenced the animal behavior variables in training. The behavior of the trainer and the form of the training, as well as the fact that the trainer is the presenter, interfered in the behavior of the horses on the horse farm and in the competitions, resulting in safer animals. However, the need for time adaptation and training management is necessary for the whole man × animal relation to get better rankings in the race competitions.

O transtorno da compulsão alimentar periódica (TCAP) foi descrito pela primeira vez nos anos 1950. Contudo, sua elevação à categoria diagnóstica apenas ocorreu em 1994, quando foi incluído no apêndice B do DSM IV, com critérios provisórios para seu diagnóstico. Trata-se de uma síndrome caracterizada por episódios recorrentes de compulsão alimentar, sem qualquer comportamento de compensação para evitar um possível ganho de peso. Incertezas quanto a seus parâmetros diagnósticos como caracterização da quantidade de alimentos ingeridos, duração de um episódio de comer compulsivo, ou mesmo o valor da perda de controle sobre a ingestão alimentar, tornam difíceis uma homogeinização de um grupo sindrômico. Desta forma, estudos epidemiológicos podem revelar diferentes dados de caracterização da população portadora deste transtorno. Isto reforça a necessidade da manutenção de estudos para avaliação desta patologia.

Binge eating disorder was first described in 1955. However, its upgrade to a diagnostic category only occurred in 1994, when it was included in appendix B of DSM IV, with provisory criteria. It is characterized by recurrent episodes of binge eating, without any compensatory behavior to prevent a possible weight gain. Uncertainties about the diagnostic criteria like the amount of food ingested, the duration or the value of the loss of control during a binge eating episode make its characterization difficult. Then, epidemiological studies may reveal the characterization of this disorder. This means that more studies are needed for an appropriate evaluation of this pathology.
