Use of infrared thermography in Quarter Horse submitted to team roping

Abstract

This study aimed to verify whether the body and local temperatures change after high-intensity, short-duration exercise (team roping) and whether different pieces of training influence these changes. To this end, twelve animals, males and females, aged 3-6 years, with an average weight of 450 kg, were used. The horses were divided into two groups: regular training (RTG) and sporadic training (STG). The surface temperatures were assessed using a specific thermal camera. Temperatures of the ocular, thoracolumbar, distal tendon (thoracic and pelvic limbs) and croup regions were measured 30 min before, immediately after, and one, two, six and 24 hours after competition simulation. In the RTG, there was an increase in surface eye temperature two hours after exercise, returning to baseline level 24 hours later. In the STG, increase in eye temperature occurred immediately after exercise and returned to baseline level two hours later. Temperature of the pelvic limb tendons and croup (right side) rose immediately after exercise and did not return to baseline level 24 hours later. Team roping exercise increased the surface temperature of the distolateral thoracic and pelvic limb, croup and thoracolumbar regions in both groups and the eye temperature in the STG. Training frequency influenced the surface temperature profile in the distolateral pelvic limb, croup and thoracolumbar regions.

Correlation between Ocular and Rectal Temperature with Intra Ocular Pressure in Horse during Exercise

“…Furthermore, our results showed a significant statistical decrease in IOP after exercise, in contrast to other findings [ 3 , 23 ]. No statistical effect was found on IOP between the a.m. and p.m. hours, suggesting that IOP is not affected by changes in the thermoregulation system which is activated between morning and afternoon as the body temperature increases after exercise [ 3 , 38 ]. The decrease in IOP observed after physical exercise may be associated with cardiovascular, systemic and hemodynamic adaptations intra- and post-exercise (such as changes in the heart rate, elevated systolic and diastolic blood pressure), which may be necessary to ensure the proper supply of oxygen and blood-transported substrates to activate the muscular system during exercise, along with the release of metabolites [ 22 , 24 , 29 ].…”

Changes in surface temperature of upper fore and hindlimbs of horses submitted to four beat gait exercise determined by thermography

“…Although some authors reported significant temperature increases in hindlimb muscle surface right after different exercises (Simon et al, 2006;Yarnell et al, 2014;Gerardi, et al, 2019), others could not detect forelimb muscle temperature variation in Quarter horses (Oliveira et al, 2018).…”

“…In addition, IRT could be used during training programs to ensure muscles are working symmetrically and indicate which terrains or training programs cause an increase in muscle workload (Yarnell et al, 2014;Gerardi, et al, 2019).…”

Efeitos da pasta a frio sobre parâmetros clínicos e termográficos em equinos

“…Segundo a Associação Brasileira de Vaquejada -ABVAQ, o mercado vinculado a atividade era de aproximadamente R$ 600 milhões de reais por ano em 2017, o que justifica os altos investimentos feitos na manutenção desses animais em bom estado clínico em busca da garantia de que estarão aptos a competir com seu máximo rendimento atlético (GERARDI et al, 2019).…”
