“…Until the age of 3 years, female donkeys intended for dairy production also do not have much contact with human subjects. This may explain the higher plasma adrenaline concentrations in younger animals, considering that adrenaline plays a predominant role in the phases preceding exercise, whereas it seems that noradrenaline has a predominant role in sustaining physical activity [24]. Although a jugular catheter was inserted at least 12 h before the blood sampling and the younger animals did not show any particular fright or fear behaviour in the [1,21] in order to prepare the body for a "fight-orflight" reaction [15].…”

“…Donkeys have a natural propensity to freeze when threatened [23]. This may explain the higher plasma adrenaline concentrations in younger animals, considering that adrenaline plays a predominant role in the phases preceding exercise, whereas it seems that noradrenaline has a predominant role in sustaining physical activity [24]. Dopamine is also involved in many biological processes in mammals, involved in cognition, emotions [25,26], control and coordination of motor activity and in brain reward systems [27].…”

“…O aumento esperado do cortisol sérico frente a um exercício físico, conforme também foi constatado neste estudo, desencadeia uma cascata de eventos endócrinos, tendo em grande parte a participação conjunta das catecolaminas (Baragli et al 2011). Estas alterações fisiológicas incluem a redução na ação da insulina, hiperglicemia e aumento de triglicérides séricos, visando a produção eficiente de energia para manutenção dos esforços musculares (Mircean et al 2007).…”

“…Hyyppä (2005) relatou que o exercício físico desencadeia a liberação de diversos hormônios, principalmente as catecolaminas, cuja principal função é a mobilização e utilização do substrato energético, através da quebra de glicogênio e lipólise, com consequente liberação de ácidos graxos livres. A liberação das catecolaminas no exercício ocorre tanto em equinos treinados quanto em não treinados (Baragli et al 2011).…”

O presente estudo teve por objetivo avaliar a influência do exercício físico de intensidade submáxima (provas de marcha) sobre as variáveis bioquímicas sanguíneas usadas na avaliação do metabolismo energético em equinos da raça Mangalarga Marchador criados no Estado do Espírito Santo. Para tal foram obtidas amostras de soro e plasma de 15 equinos, da raça Mangalarga Marchador, em quatro momentos assim definidos: antes (T0) e com 5 minutos (T1), 30 minutos (T2) e 2 horas (T3) após o término do exercício. A análise dos resultados demonstrou a não influência do exercício físico imposto sobre a glicose plasmática, com valores médios de 117,1±35,8mg/dL, 122,6±59,6mg/dL, 124,8± 48,6mg/dL e 112,9±49,1mg/dL, e sobre a insulina sérica, com valores de mediana de 6,50mUI/mL, 2,00mUI/mL, 5,85mUI/mL e 11,60mUI/mL, respectivamente, nos tempos T0, T1, T2 e T3. De forma oposta, foi possível observar uma influência significativa sobre triglicérides séricos, com valores médios de 25,4±14,9mg/dL, 42,3±17,8mg/dL, 31,4±17,7mg/dL e 25,1±15,1mg/dL, e sobre o cortisol sérico, com valores médios de 7,46±4,37mg/dL, 12,45±3,08mg/dL, 11,40±2,52mg/dL e 6,89±1,78mg/dL, respectivamente nos tempos T0, T1, T2 e T3. A interpretação destes resultados permitiu concluir que a marcha elevou as concentrações séricas de triglicérides e cortisol. Também foi possível destacar que, por tais valores encontrarem-se dentro de intervalos fisiológicos, os equinos usados estavam aptos ao nível de exercício físico imposto na ocasião.

“…Adrenaline and noradrenaline in horses have been investigated, especially in various diseases and following surgery [ 46 ], exercise [ 45 ], and as a possible emotional component in equine exercise physiology [ 47 ]. Cortisol is an indicator of the extent of acute stress, and it is widely utilized in veterinary research to evaluate the short-term stress due to handling or husbandry procedures: cortisol is a time-dependent measure with a circadian rhythm that takes 10 to 20 min to reach peak values [ 48 ].…”

Equine assisted interventions (EAIs) are recently facing an increasing popularity, and are characterized by a wide diversity of practices. However, information on the welfare of animals involved in this kind of activity is often lacking. Horses are highly susceptible to work stressors related to physical constraints and/or to the need to control emotions while interacting with humans. Considerations of the emotional state of horses involved in EAIs have multiple valences: for the safety of humans and animals involved, for the quality and efficacy of interventions, as well as for ethical reasons. The aim of this unsystematic narrative review is to summarize the different approaches used for the evaluation of horses’ stress responses, investigate their application in the context of EAIs, and discuss some methodological considerations for researchers and practitioners involved in EAI. The sources of information are mostly based on electronic databases (i.e., Medline, Scopus and Google scholar), as well as on hand searches of the references of retrieved literature, and discussions with experts in the field. At present, a few studies have investigated horses’ stress responses during EAIs, and further studies are recommended, with the final aim to derive a reliable multidimensional method for assessing a horse’s reaction during therapeutic programs, ultimately helping professionals to better develop interventions by taking into consideration the animal’s perspective.
